Objective: To observe the clinical effects of pediatric tuina plus Chinese medicine for exogenous fever in children. Methods: A total of 150 children withexogenous fever were randomly divided based on the random digital table into a control group (75 cases) and a treatment group (75 cases). The control group was treated with oral Xiao'er Chaigui Tuire Keli (<1 year old, 0.5 bag/time; 1-3 years old, 1 bag/time; 4-6 years old, 1.5 bags/time), 4 times/day. The treatment group was treated with pediatric tuina plus the intervention of the control group. The amount and usage of Chinese medicine were the same as those of the control group; tuina was conducted 1 time/day. The clinical effects and adverse reactions were observed after 3 d of treatment in both groups. The recurrence was observed within 7 d after the end of treatment. Results: The total effective rate was 92.0％ in the treatment group and 81.3％ in the control group. The difference between the two groups was statistically significant (P<0.05). There were no obvious adverse reactions in the two groups after treatment. The recurrence rate was 1.5％ in the treatment group and 13.1％ in the control group. The difference in the recurrence rate between the two groups was statistically significant (P<0.05). Conclusion: Pediatric tuina plus Chinese medicine is effective in treating children with exogenous fever.

A total of 144 patients with Graves disease were divided into 3 groups according to their disease courses (≤ 1 year,1 year ＜ course ≤ 5 years,＞ 5 years).The bone metabolic biochemical markers and bone mineral density (BMD) of 144 patients with Graves disease and 26 normal controls were observed.Compared with control group,serum levels of calcium,phosphate,alkaline phosphatase and urinary levels of phosphate and magnesium in Graves disease patients were significantly increased(P ＜ 0.01 or P ＜ 0.05),but serum levels of magnesium and 25 (OH) D3,1,25 (OH)2D3 were significantly decreased (P ＜ 0.01 or P ＜ 0.05).BMD of all sites in patients were significantly lower than that of normal controls (P ＜ 0.01 or P ＜ 0.05).

OBJECTIVETo observe the effect of Wenyang Huoxue Lishui Recipe (WHLR) containing serum on the expression of cathepsin L (CatL) in puromycin aminonucleoside-induced injury of mouse glomerular podocytes.

METHODSMouse podocyte cells (MPCs) in vitro cultured were divided into the normal control group, the model group, the dexamethasone (DEX) group, 10% WHLR containing serum group, 20% WHLR containing serum group, the vehicle serum control group. MPCs in the normal control group were cultured at 37 degrees C culture solution for 24 h. 45 mg/L puromycin was acted on MPCs in the model group for 24 h. On the basis of puromycin intervention, 1 limol/L DEX was co-incubated in MPCs of the DEX group for 24 h; 10% or 20% WHLR containing serum was co-incubated in MPCs of the 10% WHLR containing serum group and 20% WHLR containing serum group for 24 h. The vehicle serum control group was also set up by incubating with WHLR containing serum alone for 24 h. The expression of CatL and its substrate Synaptopodin in podocytes were detected by cell immunofluorescence staining. FITC-conjugated phalloidin was used to stain F-actin. A cortical F-actin score index (CFS index) was designed to quantify the degree of cytoskeletal reorganization in cultured podocytes.

RESULTSCompared with the normal control group, the expression of synaptopodin significantly decreased and the expression of CatL significantly-increased in the model group. F-actin arranged in disorder, gradually forming pericellular F-actin ring. CFS index was obviously elevated (P < 0.01). Compared with the model group, the epression of synaptopodin increased, the expression of CatL decreased, and CFS index also decreased in the DEX group, 10% WHLR containing serum group, and 20% WHLR containing serum group (P < 0.05, P < 0.01). Compared with the DEX group, the expression of synaptopodin decreased in 10% WHLR containing serum group, CFS index also decreased in 20% WHLR containing serum group (P < 0.05).

CONCLUSIONSWHLR could up-regulate the expression of synaptopodin, down-regulate the expression of CatL, and alleviate cytoskeletal reorganization of F-actin. It was helpful to stabilize the cytoskeleton of F-actin and improve the merging of podocytes.

SD rats were sampled and spiperone binding to serotonin2A receptors on brain and platelets were tested before and after a section training or long-term(3 weeks) intensive training using radiolabeled receptor assay. Results showed that there were significant increment of concentration of 5-HT in brain and decrease of 5-HT 2A R density in specific binding sites(B max ) on membranes of brain and platelets post acute intensive exercise. The downregulation of B max of 5-HT 2A R could be prevented by the supplement of BCAA+CHO during 3 weeks' intensive training. There was a positive effect on the delay of central fatigue with the supplement of BCAA+CHO during long-term intensive exercise.

The study of the anti-tumor drugs with effect of killing tumor cells, low toxicity and safety is important for cancer medicine. The silver nanoparticles(AgNP)synthesized by plant extracts have strong anti-tumor activity. The class of drugs is stable, with good curative effect and fewer side effects, which provide an important way for tumor therapy. In this paper, the recent anti-tumor studies of silver nanoparticles synthesized by active components extracted from different parts of plants are reviewed in order to provide theoretical basis for clinical antitumor applications.

BACKGROUND: Physical exercise can significantly reduce bone mass loss, relieve pain and improve bone metabolism in osteoporosis patients, but there is no evidence-based evidence. OBJECTIVE: To investigate the effect of different physical exercises on the treatment of primary osteoporosis. METHODS: Randomized controlled clinical trials regarding the therapeutic effect of physical exercise on primary osteoporosis were screened. The physical exercise group was subjected to physical exercise, and the control group had no regular exercise during the test. The main outcome measures included bone mineral density of lumbar spine L2-L4, visual analog scale score, bone metabolism index (osteocalcin, total type 1 procollagen amino terminal peptide, urine pyridinium/creatinine, blood calcium, blood phosphorus). The included outcome indicators were meta-analyzed using the Review Manager 5.3 software. RESULTS AND CONCLUSION: A total of 25 randomized controlled trials were included. Meta-analysis results showed that physical exercise could effectively improve the bone mineral density of L2-L4 segments in primary osteoporosis patients (mean difference=0.06, 95% confidence interval [0.04-0.08], P < 0.000 01, I2=89%). Subgroup analysis results revealed significant differences in the control group and five-animal exercise & Yi-Jin-Jing group, setting-up exercise group, composite exercise group, and incremental exercise group compared with control group (P < 0.05), while there was no significant difference between other exercise groups and control group (P > 0.05). Physical exercise significantly reduced the pain as determined by the visual analog scale in osteoporosis patients (mean difference=-0.93, 95% confidence interval [-1.08 to -0.79], P < 0.000 01, I2=83%). Exercise intervention could improve serum osteocalcin, total type 1 procollagen amino terminal peptide and blood phosphorus levels, and reduce urine pyridinium/creatinine and serum calcium levels. However, there was no significant difference between exercise groups and control group (P > 0.05). The results of Egger’s and Begg’s tests indicated that publication bias of the included studies was at a low level. All these findings indicate that physical exercise has significant interventional effects on bone mineral density and pain in patients with primary osteoporosis.

Objective: To investigate the effects of ATRA (all-trans-retinoicacid) combined with gamma radiation on proliferation and apoptosis of human esophageal carcinoma TE13 cells, and to explore the possible mechanism. Methods: The effect of ATRA on the proliferation of TE13 cells was detected by MTT method. When the cell growth RI (inhibitory rate) reached levels of 25%, 50% and 75%, the TE13 cells were treated with the corresponding inhibitory doses of ATRA combined with 4 Gy gamma radiation. The effects of this combination intervention on cell cycle distribution and apoptosis of TE13 cells were detected by FCM (flow cytometry). The colony-formation ability and cell viability were detected using colony-formation experiment. The expression of cyclinD1 protein was detected by FCM. Results: The inhibitory effect of ATRA on the proliferation of TE13 cells was significant in a dose- and time-dependent manner. The cell growth IRs reached 22.0%, 55.1% and 71.1% at ATRA concentrations of 0.78, 6.25 and 12.5 μmol/L, respectively. The cell viability and colony-formation efficiency were significantly decreased in TE13 cells treated with ATRA in combination with 4 Gy gamma radiation, as compared with TE13 cells receiving administration of ATRA alone. The proliferative ability of TE13 cells was significantly reduced after ATRA treatment in combination with 4 Gy gamma radiation for 24 and 48 h; furthermore, the percentage of the cells arrested at phase G0/G 1 was increased accompanying with a significantly elevated apoptotic rate. Although the combination treatment (0.78 μmol/L ATRA and gamma radiation) had a weak influence on the expression of cyclinD1 protein, which was significantly decreased in other groups (6.25 and 12.5 μmol/L ATRA). Conclusion: ATRA exerts an inhibitory influence on the proliferation of TE13 cells through down-regulating cyclinD1 expression, arresting the cells at phase G0/G1, and inducing apoptosis. A higher-concentration of ATRA combined with gamma radiation can significantly decrease the expression of cyclinD1, promote G0/G1 cell cycle arrest, accelerate apoptosis, and limit the colony formation, but a lower concentration of ATRA combined with gamma radiation exerts a little influence on cyclinD1 expression, although it may accelerate apoptosis and limit the colony-formation at some periods of time after treatment.
