Objective To verify that traditional Chinese medicines have certain price advantages compared with western medicines,and to estimate the rational increase in the compensation proportion of traditional Chinese medicine in the new rural cooperative medical system.Methods Using stratified sampling survey and literature review,the average outpatient and hospitalization expenses in the treatment of common diseases in rural areas were calculated and compared among traditional Chinese medicine,western medicine,and integrated traditional and western medicine.Results For average outpatient and hospitalization expenses,traditional Chinese medicine was lower than western medicine,integrated traditional and western medicine was lower than western medicine.and traditional Chinese medicine was lower than integrated traditional and western medicine.For hospitalization expense,traditional Chinese medicine had a 25.2%lower expense compared with western medicine.The ratios of expenses were statistically calculated,and the mathematical model for the compensation proportions of traditional Chinese medicine and western medicine in the new rural cooperative medical system was put forward.Conclusions In the implementation scheme of new rural cooperative medical system,the compensation proportion of traditional Chinese medicine in outpatient and hospitalization expenses should be increased by 25%and 33%respectively compared with western medicine.

Ojective To investigate the relationship between the serum adiponectin concentration and insulin resistance in patients with obesity and diabetic patients. Methods Fasting serum adiponectin concentration was measured by RIA in 19 normal subjects, 23 obese subjects, 31 diabetic patients without obesity and 26 diabetic patients with obesity. Results There was no significant difference in serum adiponectin concentration between nomal and obese subjects, and between type 2 diabetics without obesity and type 2 diabetics with obesity . The serum adiponectin concentrations was significantly higher in type 2 diabetics without or with obesity than that in nomal and obese subjects. There was significant difference in serum adiponectin concentration between female and male subjects. Body mass index (BMI), waist circumference(WC), waist-hip ratio (WHR), body fat percentage (BF%), fasting plasma glucose (FPG), insulin sensitivity index (ISI), triglyceride (TG) and high density lipoprotein-C (HDL-C) were significantly correlated with serum adiponectin concentration. A stepwise mulitiple linear regression analysis showed that HDL-C, FPG, WC, BF% entered the regression equation. Conclusion Serum adiponection level was associated with sex, obesity, type 2 diabetes mellitus and insulin resistance.

[Summary] To investigate the difference in serum pigment epithelium-derived factor ( PEDF) among type 2 diabetic patients before and after use of dipeptidyl peptidase-4 inhibitors linagliptin for treatment, and to explore the correlation of serum PEDF with lipids, body mass index, and HbA1C . 39 patients with recently diagnosed type 2 diabetes and 30 healthy individuals were enrolled. Baseline weight, waist circumference, body mass index, fasting plasma glucose, HbA1C , serum glutamic-pyruvic transaminase, glutamic oxaloacetic transaminase, total cholesterol, triglyceride, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol ( LDL-C) , and PEDF measured by enzyme linked immunosorbant assay were determined both in the diabetic and control subject. The treatment group was treated with oral linagliptin 5 mg/d for six month, serum PEDF and clinical parameters were determined in the diabetic group during 6 months of treatment. ( 1 ) PEDF levels were found to be comparable with the controls ( P=0. 584);LDL-C and waist circumference showed positive correlation with PEDF(P<0. 05 or P<0. 01). (2) PEDF level was significantly increased in patients with type 2 diabetes after linagliptin treatment [(3. 21 ± 1. 91 vs 2. 45 ± 1.53)μg/ml,P<0.01]. SerumPEDFlevelinpatientswithtype2diabeteswassimilartothatofhealthycontrolswith associated LDL-C and waist circumference. After linagliptin treatment, serum PEDF level was raised, suggesting that it may have certain protective effect for diabetic vascular complications.

Objective To investigate changes in serum sclerostin (SO) in postmenopausal women before and after treatment with recombinant human parathyroid hormone (1-34) [rhPTH (1-34)],and to explore the relationship of serum SO with estradiol (E2),and bone mineral density (BMD).Methods Ninety-five postmenopausal women were divided into normal BMD group (n =41) and osteoporosis group (n =54).Body mass index,alkaline phosphatase (ALP),serum E2,calcium,phosphate,and SO were determined in both groups.The patients in osteoporosis group were treated with rhPTH (1-34) 20 μg/d by subcutaneous injection and oral calcium 500 mg/d for 12 months.Serum calcium,serum phosphate,BMD,serum ALP,serum E2,and sclerostin were determined in osteoporosis group by 6 months and 12 months of treatment.Results (1) Serum level of SO in osteoporosis group was raised significantly as compared with normal BMD group (P ＜ 0.05) ; E2 and BMD were negatively correlated with SO; age and postmenopausal years were positively correlated with SO (P ＜ 0.05).(2) Serum SO was reduced gradually with treatment of rhPTH (1-34) by 6 months and 12 months (P ＜ 0.05).Conclusions Serum SO was increased in postmenopausal women,which was related to E2 and BMD,and was reduced gradually with treatment of rhPTH (1-34).SO may participate in the development of postmenopausal osteoporosis.

Objective To explore the effect of antimicrobial use density (AUD) on the detection rate of methicillin-resistant Staphylococcus aureus (MRSA) and antimicrobial resistance rate of healthcare-associated Staphylococcus aureus (HA-SA) half a year later.Methods From 2012 to 2015,all types of AUD,detection rate of MRSA,and antimicrobial resistance rate of HA-SA were calculated semiannually,correlation between antimicrohial resistance rate of HA-SA and all types of AUD in the same first half of year were analyzed with correlation analysis and multiple linear regression.Results From the first half of 2012 to the latter half of 2015,the total AUD declined from 128.2 to 49.0,except the AUD of carbapenems rose,AUD of other antimicrobial agents declined.From the latter half of 2012 to the latter half of 2015,104 249 patients were admitted to the hospital,and 1 008 strains of SA were isolated from 40 884 specimens,857 (85.02％) of which were community-associated SA(CA SA) and 151 (14.98％) were HA-SA.Isolation rate of HA-MRSA declined from 31.25％ in the latter half of 2012 to 12.50％ in the latter half of 2015;isolation rate of CA-MRSA rose from 7.08％ to 16.08％,resistance rate of HA-SA was generally higher than that of CA-SA.Antimicrobial resistance rate of HA-SA to ciprofloxacin remained the same,to levofloxacin increased,to 8 other antimicrobial agents all declined;resistance rates of CA-SA to oxacillin,ciprofloxacin,clindamycin,gentamicin,and levofloxacin increased,but to other antimicrobial agents declined;no SA strains was found to be resistant to vancomycin and linezolid.The resistance rate of HA-SA to azithromycin and erythrocin was correlated with the AUD of macrolides,resistance rate of HA-SA to clindamycin was correlated wvith the AUD of aminoglycosides,to gentamicin was correlated with the AUD of macrolides and the total AUD.Conclusion The selective pressure of antimicrobial agents is still the important cause of the occurrence of antimicrobial resistance,decreasing the AUD of antimicrobial agents will help for reducing the detection rate of HA-MRSA and drug resistance rate of HA-SA.

AIM: To investigate the effects of metallothionein (MT) induced by zinc on doxorubicin (DOX)-treated mice and to explore the potential mechanisms. METHODS: Male C57BL/6J mice were divided randomly into 4 groups (n = 6) following control, DOX, Zn and Zn plus DOX. Mice were pretreated with eikg-1, ip) or equal volume of saline, and were killed on d 4 after the last injection. Serum and hearts were collected for examination. RESULTS: Zinc pretreatment elevated cardiac MT levels significantly while other antioxidants in heart including glutathione (GSH), glutathione peroxidase (GSHpx) , superoxide dismutase (SOD), and catalase (CAT) were not altered. Severe oxidative injury occurred in the mice treated with DOX as myocardial lipid peroxidation and morphological changes manifested by myocardial fibers swelling and vacuolization and nuclear condensation or dissolution, with increased activities of serum creatine kinase and lactate dehydrogenase and depletion of GSH, GSHpx, and SOD while CAT activity was increased in compensation. However, pre-induction of MT with zinc attenuated all of these toxic changes significantly. Furthermore, DOX induced elevation of hydrogen peroxide in heart tissues was greatly inhibited by zinc pretreatment. CONCLUSION: Preinduction of MT by zinc protects the heart from DOX-induced cardiotoxicity, and this effect is possibly correlated with the property of MT on scavenging free radicals in vivo.

ObjectiveTo investigate the effect of rhPTH (1-34) and elcatonin on bone metabolism and serum secreted protein acidic and rich in cysteine ( SPARC ) in postmenopausal women with osteoporosis.Methods One hundred and twenty-four postmenopausal women with osteoporosis were randomly divided into 2 groups:One group was treated with recombinant human parathyroid hormone ( 1-34 ) [ rhPTH ( 1-34 ) ] 200 U/d by subcutaneous injection (PTH group,n =89 )and another group was treated with elcatonin 20 U/week by intramuscular injection (CT group,n =35 ) for 12 months.All patients received a basic therapy with oral calcium ( Ca 600 mg+ Vit D3125 U,q..d.).The bone mineral density ( BMD ) of lumbar spine( L2-4 ),the left femoral neck,greater trochanter,and Ward's triangle,serum calcium and phosphate were measured by baseline,6 months' and 12 months.Levels of serum bone-specific alkaline phosphatase( BSAP),serum secreted protein acidic and rich in cysteine (SPARC)were determined by an ELISA assay.ResultsBy 12 months,rhPTH ( 1-34 ) treatment significantly increased the lumbar spine L2-4 BMD 7.9％ (P＜0.05),serum calcium 8.3 ％ ( P＜ 0.05 ),serum BSAP 93.4％ ( P＜ 0.05 ),serum SPARC by 12.6％[ ( 195.68±59.57 vs 173.81 ±81.33 ) pμg/L,P＜0.05 ].Elcatonin therapy increased the lumbar spine L2-4 BMD by 3.2％ (P＜0.05) at the end of 12 months,but elcatonin did not influence serum calcium,BSAP and SPARC.The rhPTH( 1-34 ) increased lumbar spine L2-4 BMD more than elcatonin did at 12 months( P＜0.05 ).ConclusionrhPTH (1-34) could promote the bone anabolism more effectively than elcatonin did.Serum SPARC may play an important role in promoting osteogenesis by rhPTH.

Objective:To investigate the effect and safety of the hi-channel in one-stage of minimally invasive pereutaneous nephrolithotomy (mPCNL) in management of complicated renal calculi, compared with single chan-nel in two-stage of mPCNL. Methods: 57 patients underwent mPCNL in treatment of complicated renal calculi were retrospectively reviewed. 31 eases in group A underwent bi-channel in one-stage of mPCNL;26 eases in group B underwent single channel in two-stage of mPCNL. Results= The mean bleeding in the group A was 146. 4 m1(75-262.5 ml), compared with the group B 154.3 ml(75-300 ml), there was no statistically difference between the two groups (P>0.05). The mean operation time in the group A was 88. 4 rain(65-136 min), compared with the group B 123.1 min(70-180 min), there was statistically difference between them(P<0.05). Compared of the clearance rate of stone in the group A 83.9 % (26/31) and B 57.8% (15/26), there was statistically difference be-tween them (P<0.05). Conclusions:According the treatment of complicated renal calculi, the bi-ehannel in one-stage of mPCNL has shorter operation time, higher clearanee rate of stone, compared with single channel in two-stage of mPCNL. The patients need less expenses and shorter time staying in hospital. It is an ideal method.

OBJECTIVE To study the differences in toxicity between intravenous(iv)administration and aqueous solution exposure of Dichroa alkali salt(DAS)in zebrafish.METHODS ① Well-devel-oped zebrafish larvae of 2 d post fertilization(2 dpf)were randomly divided into the normal control(no treatment),solvent control(saline,iv),and DAS groups(0.125,0.25,0.50,1.00 and 2.00 mg·kg-1,iv)before being observed for 3 consecutive days after administration.A heart rate of 0 was determined as death of zebrafish,and the mortality rate,maximum non-lethal dose(MNLD),and 10 percent lethal dose(LD10)were calculated.The incidence of venous sinus congestion,pericardial edema,slowing heart rate and blood flow of zebrafish in the 0.50 and 2.00 mg·kg-1 groups were observed and calculated by somatoscopic microscopy at 4 h after drug administration.Zebrafish larvae were iv given DAS at doses of 0.041,0.136,0.412,and 0.452 mg·kg-1 while the malformation phenotypes of zebrafish larvae development were observed under a stereomicroscope for 3 consecutive days,including pericardial edema,abnormal heart rate,slow blood flow,loss of circulation,eye abnormalities,brain malforma-tions,jaw abnormalities,loss/degeneration of the liver,delayed yolk sac absorption,intestinal abnormal-ities,abnormal body coloration,body edema,curvature of the trunk/tail/nodal cord and muscle degener-ation before the incidence was calculated.②Zebrafish larvae were randomly divided into a normal control group and DAS aqueous solution exposure groups at concentrations of 2.5,5.0,10.0,25.0,50.0,75.0,and 100.0 mg·L-1,observed for 3 d until the mortality rate,LD10,and MNLD were calculated.Zebrafish were exposed to DAS aqueous solutions at concentrations of 0.32,1.06,3.20,and 11.00 mg·L-1,and the malformation phenotypes of zebrafish larvae development were observed under a stereomicro-scope for 3 consecutive days to calculate the incidence.RESULTS ① The MNLD and LD10 of DAS iv administered to zebrafish larvae were 0.412 and 0.452 mg·kg-1,respectively.Compared with the solvent control group,4 h after DAS iv administration,the incidence of sinus congestion,slow heart rate and pericardial edema in the 0.50 and 2.00 mg·kg-1 groups significantly increased(P<0.05,P<0.01),so was the incidence of slow blood flow in the 2.00 mg·kg-1 group(P<0.01).The rate of delayed yolk sac absorption was significantly increased in the 0.041,0.136,0.412,and 0.452 mg·kg-1 groups(P<0.05,P<0.01),so was the mortality rate in the 0.452 mg·kg-1 group(P<0.05),with pericardial edema observed in the dead zebrafish.② The MNLD and LD10 of DAS aqueous solution exposure for zebrafish larvae were 3.20 and 11.00 mg·L-1,respectively.Compared with the normal control group,the incidence of decreased heart rate and slow blood flow was significantly increased in the 3.20 and 11.00 mg·L-1 groups(P<0.01),so was the incidence of significantly darkened intestines in the 1.06,3.20,and 11.00 mg·L-1 groups(P<0.01).The incidence of delayed yolk sac absorption was significantly increased in the 0.32,1.06,3.20,and 11.00 mg·L-1 groups(P<0.05,P<0.01),so was the incidence of trunk curvature and lower jaw malformation in the 11.00 mg·L-1 group(P<0.01).CONCLUSION The toxic phenotypes of DAS are different between iv administration and aqueous solution exposure in zebrafish larvae.DAS aqueous solution exposure can not only lead to slow heart rate,slow blood rheology,delayed yolk sac absorption and intestinal blackening,but also induce neurodevelopmental toxicity.However,iv adminis-tration can effectively ward off significant gastrointestinal damage and neurodevelopmental toxicity.
