OBJECTIVETo investigate the effect of Busheng Huoxue Capsule (BHC) on the quality of life (QOL) in senile male osteoporosis (OP) patients, and to explore its mechanisms.

METHODSTotally 200 senile primary OP patients were randomly assigned to two groups according to random digit table method, 100 in each group. Patients in the treatment group took BHC plus caltrate-D (600 mg CaCO3), while those in the control group took alendronate (70 mg per week) plus caltrate-D. The therapeutic course was 12 months for all. Chinese medical symptom score and quality of life (QUALEFFO-41) score, bone mineral density (BMD) of lumbar vertebra (L2 -L4) and left femoral neck were compared between the two groups before and after treatment. Serum free testosterone (FT) and estradiol (E2) were also measured.

RESULTSChinese medical symptom scores and QUALEFFO-41 scores, serum FT and E2 levels increased in the two groups after treatment (P < 0.05, P < 0.01). The therapeutic effect was superior in the treatment group (P < 0.05, P < 0.01). After treatment the BMD of lumbar vertebra (L2 -L4) and the left femoral neck were somewhat improved (P < 0.05), but with no statistical difference between the two groups (P > 0.05).

CONCLUSIONBHC could effectively improve the QOL of senile male OP patients, which might be correlated with elevating the BMD levels and regulating the levels of sex hormones.

OBJECTIVETo compare the effect between mini-traumatic bone-grafting and non-bone-grafting in percutaneous K-wire fixation for treating the calcaneal fractures.

METHODSFrom 2002 to 2006, 112 patients with the type II (Paley type) fractures of calcaneus were studied. There were 56 cases in bone-grafting group involving 36 males and 20 famales,aged from 21 to 65, averaged (42.0 +/- 2.3) years; 11 cases were in type II a and 45 were in type II b; the course was from 3 to 14 days, averaged (6.0 +/- 1.2) days. And there were 56 cases in non-bone-grafting group involving 38 males and 18 famales,aged from 22 to 67, averaged (43.0 +/- 2.5)years; 13 cases were in type II a and 43 were in type II b; the course was from 2 to 15 days, averaged (5.0-2.1) days. All the cases were treated by closed reduction and percutaneous K-wire fixation, and bone-grafting group(56 cases) were treated by mini-traumatic bone-grafting, but the other group (56 cases) were not. The collapsing rate and fineness rate were compared.

RESULTSAll the cases were followed up from 5 to 52 months. There were no collapsing cases in the bone-grafting group after operation, but 3 cases occurrenced re-collapsing in the non-bone-grafting group. According to the Zhang Tie-liang's evaluation criterion, in the bone-grafting group,the results were excellent in 43 cases, good in 12, fair in 1, the fineness rate was 98.2%. In the non-bone-grafting group,the results were excellent in 37 cases, good in 16, fair in 2, poor in 1, the fineness rate was 94.7%.

CONCLUSIONTreatment of the type II fracture of calcaneus with closed reduction, percutaneous K-wire fixation and mini-traumatic bone-grafting can prevent the posterior talar articular surface of caltaneus from collapsing again after operation, enhance the union of fracture, elevate the curative effect, thus it should be taken with the standard therapeutic regimen.

OBJECTIVETo investigate the effect of allitridin injection on the expression of human cytomegalovirus (HCMV) immediate-early antigens (IEAs including IE72 and IE86) in human embryonic lung cells.

METHODHCMV AD 169 Virus strain infected cell model (MOI = 2.5 and 0.25, respectively) were established, and then treated with ICm5 and MTC doses of allitridin. Western blot was used to analyze the of IE72 and IE86 expression after the treatment, ganciclovir(GCV, IC50 and 2.3 x IC50) treatment as control.

RESULTNo matter what kind of MOI was used, both IE86 and IE72 antigens' expression was effectively suppressed by allitridin treatment, and the inhibitory rate of IE86 was almost twice of IE72's. Compared with GCV, allitridin had stronger inhibitory effect on IE86 expressing, although its efficacy on IE72 was weaker than GCV.

CONCLUSIONAllitridin could suppress the expression of IE72 and IE86, especially for IE86 expressing, maybe it is ore of key role in the mechanism of allitridin against HCMV.

A new type of floating osmotic pump of dipyridamole was designed in this paper. Apparatus three (Chinese Pharmacopeia 2005, appendix XD) was employed for in vitro dissolution test in order to evaluate the release and floating behavior in a same experiment. The system was optimized using central composite design-response surface methodology; where similarity factor (f2) between the dissolution profile of prepared formulation and the target dissolution profile was taken as dependent factor, usage amount of polyoxyethylene (X1, mg), NaCl (X2, mg) and pore former (PEG4000, X3, %) were taken as independent factors. The optimization model was f2 = -29.3 + 2.35X3 - 0.123X1(2) - 0.046X2(2) + 0.145X1X2 (R = 0.996). It was found that the dissolution profile could match the target dissolution profile under the condition of weight gain 8%-9%, X1 (20-34), X2 (30-57), X3 = 50. It is also found that the minimum usage percentage of pore former is 35.1%. The prediction results of the optimization model were good in the experiments.

Objective To optimize antimicrobial use process,ensure the rational use of preoperative antimicrobial prophylaxis during consecutive operations.Methods Antimicrobial use process in a hospital in December 2015 was optimized,6 072 cases of consecutive operations in May-November 2015 were selected as control group,5 832 cases of consecutive operations in December 2015-May 2016 were as trial group,the qualified rate of rational use of antimicrobial agents was compared between two groups,causes for delayed/prior use was analyzed.Results Before and after the optimization of antimicrobial use process,rates of antimicrobial use were 77.16％ and 78.80％ respectively,there was significant difference between two groups(x2 =8.305,P =0.004).After the optimization of antimicrobial use process,rate of antimicrobial use within 0.5-1 hour was significantly higher than that before the optimization (82.36％ vs 41.11％);rate of antimicrobial use ＜0.5 hour before skin incision decreased from 57.11％ before optimization to 4.32％ after optimization;but rate of antimicrobial use ＞1 hour before skin incision increased from 1.78％ to 13.32％.Causes for delay/prior use of antimicrobial agents was due to the lack of effective communication between doctors and nurses,which resulted in circuit nurses' inaccurate assessment on interval of consecutive operations(62.13％),the duration of intubation or puncture was too long for anesthesiologists (13.57％).Conclusion Optimizing antimicrobial use process in consecutive operations can improve prophylactic antimicrobial use rate within 0.5-1 hour,and is helpful for ensuring the efficacy of antimicrobial prophylaxis.

To observe the change of quantity and quality of platelets preserved in a full-sealed bag, and explore the difference of platelets preserved in oscillating and static conditions at (22 +/- 2) degrees C, the platelet concentrates were prepared with a CS-3000-plus blood cell separator, the platelet counts were performed with automatic blood cell analyzer and P-selectin in supernatant of platelet concentrates was detected by ELISA. The results showed that both of platelet count and P-selectin content in the platelet concentrates had no significant difference between oscillating and static preservation condition. With prolongation of preserved time, the platelet count decreased and P-selectin content increased gradually in both preserved conditions. There was no difference in the platelet counts during 0 - 72 hours preservation in both conditions, and significant difference was seen in 96 - 120 hours preservation. It was concluded that the expired date for platelet product preserved in CS-3000-plus blood cell separator full-sealed system should be 3 days. Under the condition of (22 +/- 2) degrees C, the quality of the platelet preserved in oscillating state is not superior to static preservation.

OBJECTIVETo compare the difference of polycyclic aromatic hydrocarbons (PAHs) levels in the urban air and the scores of Neonatal Behavioral Neurological Assessment (NBNA) between Taiyuan and Changzhi cities and to explore the effects of PAHs in the urban air during pregnancy on neonatal behavioral neurological development.

METHODSHigh-performance liquid chromatography (HPLC) with subsequent fluorescence detection was used to determine the PAHs levels in the cooperational hospitals in Changzhi and Taiyuan cities and the urinary 1-hydroxypyrene levels of the 297 pregnant women living Changzhi and Taiyuan cities during Nov. 2009 to May 2010. NBNA was used to determine the development of neonatal neural behavior. The differences of PAHs levels in the urban air, the pregnant women urinary 1-hydroxypyrene levels and NBNA scores between Taiyuan and Changzhi were compared.

RESULTSThere are significant differences of levels of pyrene, benz [a] anthracene, Chrysene, benz [a] pyrene, dibenz [a, h] anthracene in the urban air between Taiyuan and Changzhi (P < 0.10). The median of urinary 1-hydroxypyrene levels in pregnant women of Taiyuan was 1.140 microg/mmolCr, (P25 was 0.457 microg/mmolCr, P75 was 2.678 microg/mmolCr), the median of urinary 1-hydroxypyrene levels in pregnant women of Changzhi was 0.761 microg/mmolCr, (P25 was 0.133 microg/mmolCr, P75 was 2.095 microg/mmolCr). There are significant differences of urinary 1-hydroxypyrene levels in pregnant women between Taiyuan and Changzhi (t = -3.140, P = 0.002). There are significant differences of the NBNA scores, capacity scores, passive muscle tension scores, active muscle tension scores and general assessment scores between Taiyuan and Changzhi (P < 0.10). There was correlation between NBNA scores and urinary 1-hydroxypyrene level in pregnant women.

CONCLUSIONThe PAHs in the urban air during pregnancy may adversely affect the neonatal neurobehavioral development.

OBJECTIVETo observe the effect of rhynchophylline on methamphetamine-dependent zebrafish and explore the possible mechanism.

METHODSZebrafish were divided into control group, amphetamine group, low- (50 mg/kg) and high (100 mg/kg)-dose rhynchophylline groups, and ketamine (150 mg/kg) group. Conditioned place preference (CPP) was induced in zebrafish with methamphetamine, and the staying time in the drug box and the tracking map of the zebrafish were observed with Noldus Ethovision XT system. The protein expressions of TH, NR2B and GLUR2 in the brain of zebrafish with CPP were detected with Western blotting.

RESULTSCompared with the control group, zebrafish in methamphetamine group showed significant variations in the staying time and swimming distance in the drug box after conditioning (P<0.05) with obvious alterations of NR2B, TH and GLUR2 expressions in the brain (P<0.05). Treatment of methamphetamine-dependent zebrafish with high-dose rhynchophylline significantly reduced the variations in the staying time and swimming distance in the drug box (P<0.05) and in the expressions of NR2B, TH and GLUR2 in the brain (P<0.05).

CONCLUSIONRhynchophylline can inhibit methamphetamine dependence in zebrafish, the mechanism of which may involve the expressions of TH, NR2B and GLUR2 proteins in the brain.

OBJECTIVETo investigate the cytotoxic effect of epigallocatechin gallate (EGCG) on human hepatocellular carcinoma cell line HepG2 cells and corresponding changes of TGF-beta1-Smad pathway.

METHODSThe cytotoxic effect of EGCG on HepG2 cells was determined by MTT assay. Cell cycle and apoptosis rate were detected by flow cytometry. RT-PCR and luciferase assay were used to verify whether TGF-beta1-Smad signaling pathway is intact in HepG2. The mRNA expression of Smad 2, Smad3, Smad4 and Smad7 was detected by real-time PCR.

RESULTSEGCG induced apoptosis in the HepG2 cells in a time- and concentration-dependent manner. The proportion of G(1) phase cells was increased gradually as the concentration increased. However, the percentage of cells in S phase was decreased gradually. Annexin V/PI assay demonstrated that early apoptosis increased as the concentration increased, and late apoptosis also increased, when treated with high-concentration EGCG. The intact TGF-beta1-Smad pathway was verified by luciferase assay and RT-PCR. There was no significant effect of EGCG on mRNA level of Smad 2, Smad 3, and Smad 4 in HepG2 cells, but downregulated mRNA level of Smad 7.

CONCLUSIONEGCG can reduce apoptosis in human hepatocellular carcinoma cell line HepG2 cells. The activation of TGF-beta1-Smad signaling pathway may be involved in its cytotoxicity mechanisms.
