The therapeutic effects and mechanisms of traditional Chinese kidney-tonifying drugs in treating osteoporosis have become the focus under study. Pharmacological studies have shown that traditional Chinese kidney-tonifying drugs are promoters for the proliferation of osteoblasts, inhibitors for the activity of osteoclasts, regulators for the estrogen level and its receptor, plays important roles in promoting osteogenesis and suppressing adipogenesis of marrow mesenchymal stem cells (MSCs), modulating the function of OPG/RANK/RANKL system and the metabolism of calcium and phosphorus, as well as antioxidation. The anti-osteoporotic active ingredients and pharmacological action mechanism of traditional Chinese kidney-tonifying drugs are summarized from the perspective of molecular and cell biology in this paper, so as to provide references for the study of their mechanism of anti-osteoporosis and for the development of traditional Chinese kidney-tonifying and bone-strengthening drugs.

Objective To investigate the correlation between human leukocyte antigens-A,-B,-DRB1 (HLA-A,-B,-DRB1) high resolution alleles and chronic renal failure (CRF) caused by immunoglobulin-a nephropathy (IgAN).Method The polymerase chain reaction-sequence-based typing (PCR-SBT) method was used to investigate the genotypes of HLA-A,-B and-DRB1 high-resolution alleles in 191 cases of CRF caused by IgAN (experimental group) and 503 healthy blood donors (control group).The alleles frequencies between two groups were compared and the association between CRF caused by IgAN and the polyrnorphism of HLA was analyzed.Result (1) There were 25 alleles at A locus,48 alleles at B locus and 32 alleles at DRB1 locus in experimental group.(2) The genetic frequency of HLAA * 2901 [Pc =0.033,OR =10.738,95％ CI (1.193,96.691)],HLA DRB1 * 1106 [Pc =0.0001,OR =0.969,95％ CI (0.944,0.994)],HLA-DRB1 * 1202[Pc =0.002,OR =1.859,95％ CI (1.259,2.745)],HLA-DRB1 * 1401 [Pc =0.021,OR =0.984,95％ CI (0.967,0.998)],HLA-DRB1 * 1602[Pc=0.015,OR=1.915,95％ CI (1.157,3.17)] in experimental group was higher than in control group (P＜0.05).Conclusion There is susceptibility association of HLA-A * 2901,HLA-DRB1 * 1106,HLA-DRE * 1202,HLA-DRB1 * 1401,HLA-DRB1 * 1602 with CRF caused by IgAN.It is concluded that there is a close genetic and immunological correlation between HLA alleles and the pathogenesis of CRF caused by IgAN.

Objective To explore the method and effect of checklist tool implemented in the safety management of clinical blood transfusion in intensive care unit. Methods A checklist was specially designed according to the technical standard and check system of clinical blood transfusion. 379 patients prescribed a blood transfusion enrolled in ICU from January to May 2013 were conducted as the control group before the checklist was designed. After the application of checklist during the blood transfusion process, 846 patients prescribed a blood transfusion enrolled in ICU from June to December 2013 were conducted as the experimental group. The incidence of blood transfusion safety related adverse events between the two groups was compared. Results The incidence of adverse events was 1.32% (5 of 379 patients) in the control group, and there was no sign of adverse events occurred in the experimental group. The difference had statistical significance (χ2=11.21, P<0.05). Conclusion The application of checklist reduced the incidence of blood transfusion safety related adverse events,and effectively improved the quality of nursing safety and patient satisfaction.

Objective To compare the clinical therapeutic effects of continuous veno-venous hemofiltration (CVVH) and continuous veno-venous hemodiafiltration (CVVHDF) for treatment of patients with multiple organ dysfunction syndrome (MODS).Methods A prospective observation was conducted, seventy patients with MODS admitted to the Department of Critical Care Medicine of the Affiliated Hospital of Zunyi Medical College from September 2013 to December 2016 were enrolled, and they were divided into a CVVH group and a CVVHDF group according to different treatment, 35 cases in each group. In the CVVH group, the ultrafiltration fluid flow rate was set at 1800 mL/h, while in the CVVHDF group, the flow rate was set at 2000 mL/h for both substitution fluid and dialysate, and the blood flow of the two groups was 150-180 mL/min. The changes of creatinine (SCr), urea nitrogen (BUN), pH value, HCO3-, helper T cell (Th1, Th2) and Th1/Th2 ratio were compared between the two groups before and after treatment for 24, 48 and 72 hours.Results With the extension of time, SCr, BUN were reduced in both groups after treatment compared to those before treatment, 72 hoursafter treatment they reached the lowest value, and the degree of change in CVVHDF group was more significant than that in CVVH group [SCr (μmol/L): 150.62±32.09 vs. 180.41±30.52, BUN (mmol/L): 7.31±2.19 vs. 9.06±2.36. allP < 0.05], after treatment; the pH value, HCO3- level in the two groups had a tendency at first elevated and then lowered, 48 hours after treatment they reached the peak values, compared with those before treatment, the differences were statistically significant [CVVH group: the pH value 7.42±0.08 vs. 7.25±0.10, HCO3- (mmol/L) was 22.49±5.11 vs. 15.65±4.16; CVVHDF group: pH value 7.41±0.04 vs. 7.24±0.11, HCO3- (mmol/L) 23.24±4.78 vs. 15.65±4.16, allP < 0.05], 72 hours after treatment, they began reduced (CVVH group: pH value, HCO3- were 7.39±0.09, 22.35±4.91 respectively, CVVHDF group: pH value, HCO3- were 7.38±0.06, 23.13±4.61 respectively), but they were still significantly higher than those before treatment, and at each time point compared between the two groups, no statistical significant difference was seen (allP > 0.05). With the extension of therapeutic time, Th1, Th1/Th2 in two groups were gradually elevated after treatment, and 72 hours after treatment they reached the peak values; Th2 showed a trend of gradual decrease and after 72 hours of treatment it reached the lowest value, and the changes in CVVHDF group were more significant than those in CVVH group [Th1 (×10-2): 1.51±0.12 vs. 1.21±0.11, Th2 (×10-2): 1.64±0.65 vs. 1.70±0.18, Th1/Th2: 0.91±0.14 vs. 0.71±0.15, allP < 0.05].Conclusion Both CVVH and CVVHDF can effectively remove inflammatory mediators and metabolic products, adjust the balance of acid and base, regulate immune system in the body of patients with MODS, and the CVVHDF is more effective than CVVH.

AIM: To investigate the influence of dialysate on the cell morphology and the peritoneal membrane function in chronic peritoneal dialysis rats. METHODS: 40 SD rats were divided randomly into 4 groups. Except control group, other groups daily received infusion of 20 mL dialysate (4.25% dialysate(HG), 1.50% dialysate(LG), Riger's solution(RG)) respectively for 8 weeks. The peritoneal membrane function was investigated by peritoneal transport test, and the rat peritoneal mesothelial cells(PMCs)morphology was analyzed by the cell imprints. RESULTS: The intraperitoneal volume and net ultrafiltration in HG and LG groups were significantly lower, with D/P_(urea) significantly higher, and C_(urea) after 4 h of dialysis significantly lower than that in RG and control groups. The density of cell population from analysis of cell imprints in HG and LG groups was significantly lower, but the mean surface area were significantly larger than that in RG and control groups. These change had no difference between HG and LG group. Using the high glucose dialysate for 8 weeks significantly decreased the ultrafiltration volume ,which was significantly relate to the increasing of cell surface area (r=-0.896,P

OBJECTIVETo evaluate effects of different treatments on patients with osteoporotic vertebral fracture after percutaneous kyphoplasty in pain and function.

METHODSFrom March 2010 to March 2012,138 patients (165 vertebrae) with thoracic and lumbar vertebral osteoporotic fracture were randomly divided into three groups (control group, treatment group and comprehensive group), 46 cases in each group, and all patients were treated by PKP. Control group were treated with calcium and calcitriol after operation, treatment group added salmon calcitonin see calcimar based on control group, comprehensive group added incrementality waist musculi dorsi function exercise based on treatment group. VAS, ODI scores and BMD before operation, 3 d, 2 weeks, 1 month, 6 months and 12 months after operation were detected and compared.

RESULTSAll operation were performed successfully,38 cases (45 vertebrae) in control group, 36 cases (44 vertebrae) in treatment group and 40 cases (49 vertebrae) were obtained complete following up, there was no significant meaning in following time among three groups (P>0.05). Postoperative VAS and ODI scores at 3 d, 2 weeks and 1 month among three groups were lower than that of before operation (P<0.01). Compared with control group, postoperative VAS score at 3 d, 2 weeks and 1 month were decreasedin treatment group and comprehensive group, but there was no significant meaning in ODI scores (P>0.05). At 6 and 12 months after operation,there was no significant differences in VAS and ODI between control group and treatment group (P>0.05), while VAS score in comprehensive group decreased much than other two groups,decreased continuously (P<0.01). At 12 months after operation, BMD among three groups were increased more than preoperative,and BMD in comprehensive group was more obviously than that of in control and treatment group.

CONCLUSIONPKP, an effective method for the treatment of thoracic and lumbar vertebral osteoporotic fracture, could improve short-term clinical effects by adding calcitonin with calcium supplements and activated vitamin D. Waist musculi dorsi function exercise could improve long-term clinical effects of PKP and improve quality of life.
