METHODS:Retrieved from VIP,Wanfang Database,CJFD,Medline,PubMed,Elsevier,Springer,Web of Science and Ovid,randomized control trials (RCT) about reinforcing kidney and invigorating spleen principle (test group) versus other meth-ods(no reinforcing kidney and invigorating spleen principle,control group)in the treatment of POP were collected. Meta-analysis was performed by using Rev Man 5.3 software provided by Cochrane after data extraction and quality evaluation modified by Jadad scale. RESULTS:Totally 28 RCTs were enrolled,involving 2849 patients. Results of Meta-analysis showed,the total effective rate [OR=3.80,95%CI(2.76,5.23),P<0.001],BGP level [MD=2.23,95%CI(1.80,2.66),P<0.001],BMD level of femoral neck [MD=0.04,95%CI(0.00,0.08),P=0.05] and BMD level of lumbar spine [MD=0.07,95%CI(0.03,0.11),P=0.001] in test group were significantly higher than control group,ALP level [MD=-5.59,95%CI(-10.51,-0.66),P=0.03] and VAS score [MD=-1.38,95%CI(-1.87,-0.89),P<0.001] were significantly lower than control group,with statistical significance. There were no significant differences in U-Ca/Cr [MD=-0.07,95%CI(-0.17,0.02),P=0.12] and serum Ca2+ level [MD=0.16,95%CI (-0.07,0.39),P=0.17] in 2 groups. CONCLUSIONS:Reinforcing kidney and invigorating spleen principle can improve patients' osteogenesis during bone metabolism,reduce the activity of the osteoclastic process and relief patients'pain in the treatment of POP.

Objective: To explore correlation between plasma oxidized low density lipoprotein (ox-LDL) and endothelial injury degree in patients with coronary heart disease (CHD).Methods: A total of 80 CHD patients were enrolled as CHD group, and 21 healthy subjects were selected as healthy control group.Plasma ox-LDL, circulatory endothelial cell count (CEC), nitric oxide (NO) levels were measured and compared between two groups, and their correlation was analyzed.Results: Compared with healthy control group, there were significant rise in plasma ox-LDL level[(350±173) μg/L vs.(687±169) μg/L]and CEC[(2.5±0.5) ×106个/L vs.(9.0±1.7) ×106个/L], and significant reduction in NO level[(77.4±21.1) μmol/L vs.(52.3±16.6) μmol/L]in CHD group, P<0.05 or <0.01.Spearman correlation analysis indicated that ox-LDL was significant positively correlated with CEC (r=0.793, P=0.019), and ox-LDL, CEC were significant negatively correlated with NO level (r=-0.782,-0.952, P=0.013, 0.021).Conclusion:There are significant positively correlation between ox-LDL and circulatory endothelial cell count(Vascular endothelial injury degree) in CHD patients, therefore, its treatment should focus on anti-inflammatory and endothelial cell function protection.

BACKGROUND:Mycobacterium tuberculosis heat shock protein 10 (r-Mt cpn10) is one of the main factors that cause bone tuberculosis dissolution and absorption as wel as inhibits the proliferation of osteoblasts. Receptor activator of nuclear factor kappa B ligand and osteoprotegerin are the important factors influencing bone metabolism.
OBJECTIVE:To observe the effect of r-Mt cpn10 on human osteoblast proliferation, alkaline phosphatase secretion, expression of receptor activator of nuclear factor-kappa B ligand mRNA and osteoprotegerin mRNA. METHODS:Human bone marrow stromal cel s were induced to differentiate into osteoblasts, and osteoblasts at passage 3 were cultured with various concentrations of r-Mt cpn10 (0.1, 1, 10 mg/L). Osteoblasts cultured without r-Mt CPN10 were assigned as controls.
RESULTS AND CONCLUSION:MTT assay results showed that, compared with control group, r-Mt cpn10 at different concentrations inhibited osteoblast proliferation and alkaline phosphatase secretion (P<0.05). RT-PCR analysis showed that, r-Mt cpn10 at different concentrations increased receptor activator of nuclear factor-kappa B ligand mRNA expression (P<0.01), and inhibited osteoprotegerin mRNA expression in a concentration-dependent manner (P<0.01). 10 mg/L r-Mt cpn10 exhibited the strongest effect (P<0.01). The r-Mt cpn10 can inhibit osteoblast proliferation and alkaline phosphatase activity, and it may influence bone metabolism by regulating the expression of receptor activator of nuclear factor-kappa B ligand mRNA and osteoprotegerin mRNA.

Objective To investigate the protective effects of aspirin on hypoxic brain neural cells of rat and the effects of extracellular calcium on the neuroprotective effect of aspirin. Methods The hypoxic cell model was established by adding Na_2S_2O_4 to the calcium or calcium free medium. Cultured primary cortical neurons of rat were pretreated with ASA in vitro. The change of intracellular free calcium and neuroglobin (NGB) were observed and analyzed by laser scanning confocal microscope. Results The expression level of [Ca~(2+)] i and NGB increased significantly in the chemical hypoxia group ( P < 0. 05 ). ASA can attenuate the increase of [ Ca~(2+) ] i and NGB in the hypoxic group and calcium-free hypoxia group(P <0. 05). Conclusion Aspirin can inhibit calcium overload and the hypoxia-induced expression of NGB, so protect rat brain cells against hypoxia.

A 46 year-old female patient underwent cholecystectomy under general anesthesia. During the preoperative preparation, pulmonary edema developed from fluid overloading in the early septic condition. Pulmonary edema contributed significantly to the acute respiratory failure, which played a major role in the pathogenesis of multiple organ failure. For this condition, early surgical intervention is most important. After preoperative evaluaion, the authors anesthetized the patient with Morphine, used Enfluane intermitently, along with pancronium and oxygen and used endotracheal semiclosed circle absorption techniques with CMV incorporated PEEP. PEEP level was 5cm H2O. Inspired oxygen fraction was 1.0. Arterial oxygen tension increased from 62 torr to 183 torr despite the overt pulmonary edema. A-aDO2 was greater than 480 mmHg during the anesthesia of 2 hrs 40 minutes. For further treatment of pulmonary edema and postoperative respiratory care, synchronized IMV with PEEP, along with conventional methods for pulmonary edema and sepsis, were used in the ICU. After 6 days of intensive care, the patient was transferred to the general ward in good cardiovascular and respiratory function.
