Objective To analyse the effects of OPG (osteoprotegerin, OPG) at different concentrations on activity of osteoclasts (osteoclasts, OC) , and the relationship between them in physiological activity and function.Methods The bone marrow cells of six weeks old female mice were collected and cultured in vitro on the basis of adding different levels of OPG(10, 20, 50, 100 μg/L).The relationship between OPG and OC were analysed by tartrate resistant acid phosphatase ( TRAP) staining, F-actin cytoskeleton staining and bone resorption pits.Results OC showed adherent growth within 1h cultured, and there were no large multicore OC.Cultured for 5 days, the smaller monocytes gradually began to fusion with each other to form multinucleated cells and showed distinctive characteristics.After three days OPG treatment, the number of multicore cells gradually reduced with OPG concentration increaseing in experimental group, and showing a negative correlation between them(r=-0.516,P<0.05).And there were only a small amount of multinucleated cells at OPG concentration of 50 μg/L.At 20,50 μg/L of OPG concentration, OC number significantly decreased compared with control group (P<0.05), and when the concentration of OPG was 100μg/L, OC number showed significant reduction (P<0 01).the experimental group OPG bone resorption lacunae area, density and decrease the degree were positively correlated with concentration of OPG (r=0.459;r=0.426;r=0.389,P<0.05), and the area had a significant difference when two groups compared.Conclusion The inhibitive effects of OPG on OC function and activation increase with concentration increasing.

Objective To compare effects between the laparoscopic surgery and open surgery for the bigger adrenal adenoma(＞4cm) patients in Qinghai.Methods Altogether 57 cases of bigger adrenal adenoma patients(＞4cm)in the affiliated hospital of Qinghai university and Qinghai People's Hospital from 2012 to 2016 were selected and divided into two groups (A and B) according to surgical programs difference.Group A (23 cases)wcre givcn laparoscopic surgcry and Group B (34 cases)were given open surgery (And 2 cases in group A turned into open surgery were out of statistics).The operative time,blood loss,hospital stay and drainage tube removal time were compared.Results The operative time,blood loss,hospital stay and draiuage tube removal time in Group A were significantly better than those in Group B,with statistical significance (P ＜ 0.05).Conclusion The use of laparoscopic surgery for the bigger adrenal adenoma(＞4cm) patients is safer and more effective than open surgery.

Objective To evaluate the risk factors of gallstone occurrence after gastrectomy for gastric cancer.Methods Relevant documents published from 1990 to 2014 were retrieved through Pubmed,Cochrane Library,Embase,Web of Science CNKI,Wan Fang and VIP databases search.The Meta-analysis was applied with RevMan 5.3 software for Odds ratio and 95％ CI.Results 24 studies were selected for this Meta-analysis which included 3 randomized controlled trials,13 cohort studies and 8 case-controlled studies.These 24 studies included patient number which ranged from 32 to 893.The pooled OR (95％ CI) and P values of OR (95 ％ CI) for physiologic digestive tract reconstruction were 0.53 (0.44 ～ 0.65,P ＜ 0.05) ;amount of resection of stomach,1.98 (1.29 ～ 3.04,P ＜ 0.05) ; lymphadenectomy,0.38 (0.21 ～ 0.72,P ＜ 0.05) ; vagotomy,0.24 (0.13 ～ 0.45,P ＜ 0.05) ; and pylorus preservation,0.70 (0.48 ～ 1.02,P ＞ 0.05).Conclusions Physiologic digestive tract reconstruction and vagus nerve preservation reduced occurrence of gallstones after gastrectomy.On the other hand,total gastrectomy and extensive lymph node dissection increased the occurrence.There was no significant difference in the occurrence of gallstones whether there was pylorus preservation or not.

OBJECTIVE: To establish a RP-HPLC method by pre - column derivatization to determine the contents of mi-cronomicin sulfate.METHODS:Kromasil C18 column( 150mm X 4.6mm,5u),mobile phasewater-ice acetic acidmethanol(30 5 : 65) in 0.02mol/L sodium -heptanesulfonate. The detection wavelength was set at 330nm.RESULTS:The linear range was 0.0 976mg/ml-0.9 760mg/ml,(r = 0.9 999),the RSD of the replicate test was 1.0%(n = 6) .CONCLUSION:The method is specific,accurate and sensitive.

The mechanism of the development of sporadic renal cell carcinomas is complicated,which is different from that of hereditary renal-cell carcinoma.Genetics abnormality such as loss of 3p,VHLgene mutations may help differentiate pathological subtype of renal cell carcinoma and some gene markers may be useful predictors for prognosis.The current status of genetic study in renal cell carcinomas is reviewed in this article.

OBJECTIVETo observe the clinical effect of Lingtong Capsule (LC) in treating primary dysmenorrhea (PD).

METHODSTotally 59 PD patients took LC, while 59 patients in the placebo group took placebo capsule, two pills immediately when they felt dysmenorrhea. Their pain levels were quantitatively classified. The pain score was assessed at an interval of 30 min using visual analogue scale/score (VAS) while taking medicine and within two h after taking medicine. It was assessed as effective when the pain level was reduced by more than or equal to 50% within 2 h.

RESULTSThe total effective rate was 69.49% (41/ 59) in the LC group and 20.34% (12/59) in the placebo group (P < 0.01). The analgesia effect was obviously superior in the LC group 60 min after taking medicine (P < 0.01). LC showed better effect in treating mild, moderate, and severe PD (P < 0.05).

CONCLUSIONLC showed obvious analgesia effect on PD.

Objective To study the reliability of clinic diagnosis of hepatitis B virus(HBV)-associated glomerulonephritis.Met- hods Renal biopsy was carded out in 103 cases with clinically-diagnosed HBV-associated glomerulonephritis. The diagnostic consistency and clinical difference were evaluated.Results Sixty nine cases with clinically-diagnosed HBV-associated glomerulonephritis were confirmed through renal biopsy, 29 cases were excluded from HBV-associated glomerulonephritis. The pathologic diagnosis and clinical diagnosis methods were highly correlated and has significant difference(P

BACKGROUND: Studies regarding synthesizing composite bone repair materials with organic macromolecules as mineralizers template are the hot research spot. However, reports concerning using agar as bone repair materials are few. OBJECTIVE: To synthesize a novel agar-hydroxyapatite composite material, and to evaluate its physical and chemical properties as well as cytocompatibility.METHODS: ①A certain amount of the non-nano-hydroxyapatite in hydrochloric acid solution was added into a certain amount of agar sol, and the reaction system was adjusted with PH value of 7-8. And then the precipitate was lyophilized to obtain the composite of agar-hydroxyapatite.②The third generation of rat bone marrow stromal cell (BMSC) was co-cultured with agar-hydroxyapatite. And the growth of cells was observed at days 1, 3 and 5 after culture. RESULTS AND CONCLUSION: The results of X-ray diffraction patterns, Fourier transform infrared spectrometer (FTIR), thermal analyzer, transmission electron microscope, and scanning electron microscope showed that agar could manipulate the growth of hydroxyapatite, and hydroxyapatite nanocrystals was equably formed on the agar-fibers with high porosity. The BMSC grew well in the composite and form a clear cytoskeletal at days 3 and 5 after culture. The results reveal that agar-hydroxyapatite composite has good physical and chemical properties and cytocompatibility.
