Background
Osteoporosis is a systemic metabolic bone disease characterized by a decrease in bone mass and destruction of the bone microstructure. It is manifested by increased bone fragility and susceptibility to fracture. Currently about 2 million people worldwide suffer from osteoporosis. The incidence of hip fractures due to osteoporosis is increasing worldwide, and the elderly population is mostly affected by the risk of fractures. The total number of disabilities per year is 580 million counted worldwide. 51% of this number are due to fractures, occurring primarily in europe and america. Thus, osteoporotic fractures are considered to be a significant cause of mortality and morbidity in developed countries. The most common type of osteoporosis is associated with postmenopausal women aged 50 and older. Of the elderly over age 50, 1/3 women and 1/5 men are threatened by osteoporosis. The survey results of the Ministry of health of China from 2002 to 2005 show that the prevalence rate of osteoporosis is 8.8%, and the prevalence rate of chronic diseases of famous Chinese residents is the third place. Therapeutic agents for osteoporosis are generally drugs such as injections of hormones, calcium supplements, and bone resorption inhibitors. After long-term administration of drugs or hormones, the drugs or hormones can cause obvious side effects on the organism.
Bifidobacterium lactis (Bifidobacterium lactis) has been reported to have various health effects such as immunomodulation and intestinal health, and has been reported to be used for solid beverages.

4. Detection of efficacy of preventing and treating osteoporosis
4.1 Deovariectomized rat animal models and probiotic intervention
Culturing Bifidobacterium lactis BL-99 strain in MRS liquid culture medium at 37 deg.C for 16 hr, centrifuging at 4 deg.C and 2500rpm for 10min, collecting thallus, washing with Phosphate Buffer Solution (PBS), freeze drying, and storing at-18 deg.C or below. Is used for the experimental study of the efficacy of preventing and treating osteoporosis.
85 adult female SD rats with the age of 17 weeks with the body weight of 200-300 g. The rats were randomly divided into 3 groups of 10 rats each. 20 rats were subjected to ovariectomy, and the remaining 10 rats were subjected to sham surgery. Rats were exposed to light/dark for 12h daily at room temperature around 25 ℃ with free access to water. After 12 weeks of surgical intervention, animals in the model investigation group are sacrificed, samples of uterus, thighbone, shinbone and the like are collected, and osteoporosis related indexes such as uterus coefficient, bone microstructure morphology, bone structure model parameters and the like are measured.
After the animal after operation has a rest for two weeks, the animal begins to be administered by gavage, and the treatment course is once a day for 12 weeks continuously. Feeding BL-99 probiotics to ovariectomized rats, and feeding distilled water to a sham operation group and an ovariectomized blank control group; the animals were dosed as follows:
the specific grouping of animals is as follows:
group 1-sham blank control (sham), 10, blank solvent;
group 2-ovariectomized blank control group (OVX), 10, blank solvent;
group 3-Deovariectomized + Probiotics BL-99 group, 10, Probiotics dose 109CFU/mL。
The body weight changes of the animals before and after the intervention are shown in fig. 1A. After successful model establishment, the weight of the sham-operated group was significantly lower than that of each of the other ovariectomized groups, consistent with significant weight gain in postmenopausal women. Each intervention group had some increase in body weight during the 12 week intervention period. Compared with the ovariectomized blank group and the ovariectomized probiotic BL-99 intervention group, the weight of the ovariectomized blank group has no significant difference before and after the intervention.
After 12 weeks of dry prognosis, the animals were sacrificed, the weight of the uterus was collected, weighed and recorded, and the uterine coefficient (i.e., the ratio of the weight of the uterus to the weight of the body) was calculated. The experimental results (fig. 1B) show that there is a very significant difference in uterine coefficients between the ovariectomized OVX group and the sham operated group (P <0.001vs. sham operated), indicating significant atrophy of the uterus following ovariectomy with a decrease in vivo estrogen. And the ovariectomized blank group and the ovariectomized + probiotic BL-99 intervention group have no influence on the weight of the uterus, which indicates that the ovariectomized blank group and the ovariectomized + probiotic BL-99 intervention group have no estrogen-like side effect.
4.2 bone histomorphometry
The proximal tibia 1/3 is cut along the sagittal plane and the material is selected at 1X 0.5cm3Soaking in 10% EDTA/PBS (PH7.4) decalcifying liquid for about 1 week, changing liquid once every 3 days, dehydrating conventionally, embedding paraffin, staining by HE along sagittal plane (thickness 4 μm), determining total tissue area, trabecular area and total girth of trabecular, and calculating trabecular area percentage, trabecular number, trabecular thickness and trabecular separation degree by calculation formula. The bone tissue slices are also used for observing the appearance, arrangement, morphological structure integrity and the like of the trabeculae.
After probiotic BL-99 intervenes for 12 weeks, HE staining results (figure 2A) show that the trabecular bone of the sham operation group is closely arranged and has a complete structure; and compared with the false operation group, the area percentage of the trabecular bone is obviously reduced (P <0.001vs. the false operation). Compared with the OVX blank group, the probiotic BL-99 group can increase the trabecular bone area percentage by about 12.5% (OVX: 16.8 +/-2.5%, OVX + BL-99:18.9 +/-1.8) (P <0.05vs. OVX) (figure 2B), and the probiotic BL-99 can inhibit bone loss caused by estrogen deficiency and has a certain protection effect on bones.
Osteoclasts are the major cells responsible for bone resorption in the body and play an important role in bone development, growth, repair, and remodeling. Osteoclasts are derived from the monocyte-macrophage system and are specialized terminally differentiated cells that can be formed into large multinucleated cells from their mononuclear precursor cells by cell fusion. Osteoclasts correspond functionally to osteoblasts. The two are synergistic and play an important role in the development and formation of bones. Highly expressed Tartrate Resistant Acid Phosphatase (TRAP) is one of the major markers of osteoclasts. Results of tibial TRAP staining are shown in fig. 3A, with positive staining as a result of staining wine red to the osteoclast cytoplasm. The number of osteoclasts stained by TRAP on the surface of tibia in the rats in the OVX blank group was significantly higher than that in the sham-operated rats. Compared with OVX blank rats, the number of TRAP-stained osteoclasts in the probiotic BL-99 group is significantly reduced by about 17.9% (OVX: 22.3 + -1.1%, OVX + BL-99:18.3 + -0.6) (P <0.05vs. In vivo, estrogen can inhibit the activity of osteoclast, and induce the apoptosis of osteoclast so as to play the role of bone resorption resistance. In OVX animals, the inhibitory effect on osteoclasts was lost due to significantly lower estrogen levels, the number of osteoclasts and the ability to resorb bone were significantly increased (fig. 3B), and the final result was a significant decrease in cancellous bone mass. The results from fig. 2A, 2B and 3A, 3B suggest that BL-99 intervention inhibits OVX-induced loss of bone mass, possibly by reducing the number of osteoclasts.
4.3 measurement of Biochemical indicators
The biochemical indicators measured include blood calcium, blood phosphorus, serum Osteocalcin (OCN), type I collagen C-terminal peptide (C-terminal peptides of type I collagen, CTX-I). The method adopts atomic absorption spectrophotometry to measure the blood calcium and the blood phosphorus, and the serum sample is directly measured. The kit for detection comprises: calcum Test(REF 0155-225),Phosphorus Test (REF 0830-. However, compared with the OVX blank group, the probiotic BL-99 dry group can obviously improve high serum calcium ions (OVX: 2.28 +/-0.02 mg/dl, OVX + BL-99:2.49 +/-0.03 mg/dl) by about 10 percent and phosphorus ions (OVX: 1.02 +/-0.08 mg/dl, OVX + BL-99:1.41 +/-0.11 mg/dl) by about 40 percent.
Serum osteocalcin is an active polypeptide secreted by osteoblasts and plays an important role in regulating bone metabolism, with levels reflecting osteoblast activity. The C-terminal peptide of type I collagen is a small fragment of type I collagen after degradation, and the content and change of the C-terminal peptide can evaluate the bone resorption state. Serum osteocalcin and type I collagen C-terminal peptide were measured using an ELASA kit, and the measurement was performed according to the instructions in the kit. The kit used for detection is as follows: the Rat Osteocalcin ELISA Kit, Rat C-telopeptide of Collagen alpha-1(I) chain ELISA Kit, was manufactured as SAB (SAbiosciences, USA).
As shown in FIGS. 4A-4D, compared with the OVX blank group, the probiotic BL-99 dried group significantly increased serum osteocalcin levels by about 44.6% (OVX: 68.6 + -16.4 pg/dl, OVX + BL-99:92.6 + -24.3 pg/dl) and decreased serum type I-collagen C-terminal peptide by about 14.6%, but had no statistical significance.
4.4 detection of bone specimen PCR
This example continues to study and examine gene expression in bone specimens associated with osteoclastogenesis and osteoblastogenesis. Probiotic BL-99 intervenes in the same manner as in example 2. After total RNA was extracted from bone tissue using Trizol, the RNA was reverse transcribed into cDNA using a reverse transcription kit, followed by PCR amplification using different gene primers (see table below).
Compared with an OVX blank control group, the probiotic BL-99 intervention group can obviously improve the gene expression of Osteoprotegerin (OPG) without obviously influencing the gene expression of RANKL, so that the ratio of OPG/RANKL is increased. RANKL binds to RANK receptors on the surface of osteoclasts, promotes differentiation and activation of osteoclasts, and inhibits apoptosis thereof; osteoprotegerin OPG prevents binding of RANKL to RANK, thereby preventing osteoclast activation, inhibiting osteoclast function, reducing bone resorption, and acting as a negative regulator. The ratio of OPG/RANKL suggests that osteoclast levels are regulated in vivo. The research finds that the expression ratio of OPG/RANKL gene is increased after BL-99 intervention, the ratio is increased by about 75% from 1 to 1.75 of an ovariectomized blank group, and the result indicates that BL-99 has an obvious effect of inhibiting osteoclast formation.
In addition, as shown in fig. 5A to 5E: compared with an OVX blank group, the BL-99 intervention group can improve the gene expression level of osteocalcin by about 1.1 times (OVX: 0.908 +/-0.107, OVX + BL-99: 2.075 +/-0.643) and alkaline phosphatase by about 37.8% (OVX: 0.990 +/-0.217, OVX + BL-99: 1.364 +/-0.513), and the expression water of the two genes is closely related to the bone formation capacity, so that BL-99 intervention can promote the formation of new bone and antagonize the loss of bone mass caused by OVX by promoting the expression of related genes of the bone formation.
The results of the above studies confirm that: the bifidobacterium lactis BL-99 can obviously inhibit the loss of bone mass caused by ovariectomy or low estrogen, and improve the blood calcium and the blood phosphorus.

The BABL/c mice of 6 weeks old are raised in a clean animal room with temperature of 22 ℃, humidity of 10-60%, 12-hour illumination of alternating light and shade, and fed with standard feed and freely drinking water. Adaptive feeding was performed for 5 days, and 182 mice were randomly divided into 13 groups of 14 mice each, and the grouping is shown in Table 19.
TABLE 19 Experimental groups for regulating intestinal flora
Before beginning the gavage, the feces of each mouse were collected under sterile conditions, labeled, stored at-20 ℃ and tested for intestinal flora. The test was performed by gavage of 0.2ml/10g of each test substance, the control group was performed by PBS for 1-14 days, and the test groups were performed by gavage of test substances at the corresponding doses according to Table 19. Mice were weighed once a week and gavage was adjusted according to body weight. Collecting feces of each mouse under sterile condition after 14 days, marking, storing at-20 deg.C, and detecting intestinal flora.

At the genus level, BL-99 in the probiotic group mouse intestinal flora significantly increased the relative abundance of Lactobacillus (Lactobacillus) in the mouse intestinal tract compared to the control group, and BL-99 low dose group increased Lactobacillus (Lactobacillus) most significantly. The BL-99 dead bacteria high-dose group has obvious inhibition effect on desulfurization vibrio (Desulfovibrio) and enterobacter (enterobacter).
The inhibitory effect of BL-99 on the pathogenic bacteria helicobacter pylori, Escherichia coli-Shigella is shown in Table 21.
TABLE 21 inhibitory Effect of BL-99 on pathogenic bacteria
The pathogenic bacteria are analyzed, and the result also shows that the BL-99 low-dose group has a remarkable inhibiting effect on Helicobacter pylori (Helicobacter), all groups have an inhibiting effect on Escherichia-Shigella (Escherichia-Shigella), and the killing effect is better.
The experiment shows that the balance of intestinal flora can be adjusted by supplementing BL-99 in the low-dose group, the growth of beneficial bacteria is promoted, harmful bacteria and even pathogenic bacteria are inhibited, and the dead bacteria are also effective, so that the BL-99 or BL-99 dead bacteria in the low-dose group can play a potential health role.
Example 2: solid beverage containing bifidobacterium lactis BL-99
Referring to the fermentation process flow shown in fig. 6, bifidobacterium lactis BL-99 (i.e. bifidobacterium lactis with the preservation number of CGMCC No. 15650) provided by the invention is subjected to anaerobic culture in a TPY liquid culture medium. TPY liquid Medium (g/L): 10.0 parts of hydrolyzed casein, 5.0 parts of soytone, 2.0 parts of yeast powder, 5.0 parts of glucose, 0.5 part of L-cysteine, 2.0 parts of dipotassium phosphate, 0.5 part of magnesium chloride, 0.25 part of zinc sulfate, 0.15 part of calcium chloride, 0.0001 part of ferric chloride, and 801.0 parts of Tween, wherein the pH value is 6.5 +/-0.1. The fermentation broth after primary and secondary amplification culture is centrifuged at 2500rpm for 10min at 4 ℃ to collect the thallus. Freeze drying the collected thallus to obtain BL-99 active bacteria powder, and storing at-18 deg.c below.
The solid beverage of this example, solid beverage product specifications, were formulated according to the following ingredients in table 22: 2000 mg/bar.
