Objective: To understand the effects of remuneration incentive and their influences on job satis-faction in county public hospital. Methods: Stratified random sampling was adopted. Six county public hospitals in county level in Heilongjiang province were selected as the sample. Exploratory factor analysis was used to ana-lyze the remuneration incentives, descriptive statistical analysis and logistic regression analysis were used to ana-lyze the effects and their influences on work satisfaction. Results: remuneration incentives are divided into four dimensions that comprised a total of 16 items, which including direct material rewards, indirect material re-wards, occupational rewards and social rewards. The surgeon’s job satisfaction is higher than the physician, and is lower than the obstetrics and gynecology and pediatrics. Technician and nurses’ satisfaction is lower than the general practitioner. The medical staff who worked less than5 years has the lowest satisfaction. Authorized staff’s satisfaction is lower than off-staff. Direct material rewards and occupational rewards are related to job satisfac-tion. Conclusions:Material rewards were in low level, and non-economic incentive was insufficient. The salary incentive for highly educated talents should be strengthened.

Two new polyesters, talapolyesters G-H (1-2) were isolated from the wetland soil-derived fungus Talaromyces flavus BYD07-13, and their structures were determined by NMR and MS spectroscopic data. The absolute configurations of the residues were determined by alkaline hydrolysis. The cytotoxicity against five tumor cell lines (HL-60, SMMC-7721, A-549, MCF-7 and SW480) of 1-2 was examined.

Objective To examine supine fulcrum pressurized radiograph to predict spinal flexibility in adolescent idiopathic scoliosis (AIS). Methods 1. Empirical study: put two points (A and B) on one side of the plastic stick and one point on the other side ( C), pressurize on the plastic stick when point C is in the middle of A and B, and then measure the projection shifting of point A. Repeat the pressure test when the distance between A and C doubled. Analyze the effect of increasing distance on diminishing pressure. 2.Clinical study :45 patients ( 16 males and 29 females) underwent standing anteroposterior radiograph ,fulcrum lateral flexion radiograph, supine lateral flexion radiograph. The Cobb's angles were measured and the flexibility ratio was determined on preoperative fulcrum radiograph. Results (1) If the length of A and C was 25 cm, pressurize on point C, when pressure quantitative scale number located 1 scale and 2 scale of the rule, projection shifting of point A were 5 cm and 10 cm. If the length of A and C was 50 cm, pressurize on point C, when pressure quantitative scale number located 1 scale and 2 scale of the rule, projection shifting of point A were 8 cm and 15 cm. The longer the distance, the lesser the pressure force of plastics stick. (2)The Cobb angles and curve flexibility provided by fulcrum lateral flexion radiograph had significant difference from that provided by supine lateral flexion radiograph in male group and female group. Cobb angles of male group was 28. 6°± 4. 1 °, 16. 7°± 4. 6° respectively (t= 7. 438, P ＜ 0. 01 )and curve flexibility was 47. 6% ±8. 1% ,69. 4% ± 8. 5% respectively( t = 7. 438, P ＜ 0. 01 ). Cobb angles of female group was 24.5°± 2. 7°,12. 6°±2. 4° respectively(t = 17. 540,P ＜0. 01 )and curve flexibility was 53.4% ±5.2% ,76. 0% ±4. 7% respectively(t = 17. 54, P ＜ 0. 01 ). The flexibility of spinal main curve of female patients was obviously higher than male patients. Conclusions Supine fulcrum pressurized technique can make up for the insufficiency of supine lateral flexion technique, and provide a convenient, safe, precise and useful method for evaluation of spinal flexibility in AIS.

Objective To investigate the association between donor complement factor component 7 (C7) rs6876739 gene polymorphisms and risk of early bacterial infection following orthotopic liver transplantation (OLT).Methods A total of 113 patients who had undergone OLT in Shanghai General Hospital between July 2007 and January 2011 were included.A single nucleotide polymorphism (SNP),donor C7 rs6876739 was genotyped and analyzed together with clinical data.Results We demortstrated that donor C7 rs6876739 CC genotype had higher risk of early bacterial infection than TT genotype following OLT (55.6％ vs.26.5％,P =0.021).The multivariate logistic regression analysis revealed that gender (P =0.018),biliary complications (P =0.018),ICU stay after LT (P＜0.001) and donor C7 rs6876739 genotype (P =0.001) were identified as independent factors of early bacterial infection.Conclusion Donor C7 rs6876739 genotype polymorphism is associated with early bacterial infection following OLT and may be a new marker of risk for the development of potentially serious bacterial infection after liver transplantation.

BACKGROUNDTo determine the relationship between human papillomavirus infection, cervical carcinoma, pre-cancerous lesion and condyloma acuminatum.

METHODSFrom January 2004 to August 2005, 1086 inpatients in department of dermatology and department of gynaecology and obstetrics in Southwest Hospital and No. 302 Hospital with cervical lesions and condyloma were reviewed. All specimens were detected for HPV-DNA using techniques of Gene Array and fluorogenic quantitative polymerase chain reaction (FQ-PCR). All detections of HPV-DNA were performed in the first admission before the patients underwent any examination or treatment.

RESULTSThe positive rates of HPV-DNA detection were 100% in cervical intraepithelial neoplasia (CIN) I, and II and cervical carcinoma. Among these, the main subtype was HPV 16. But some of the patients were found to be positive for more than 2 subtypes of HPV. While the commonest HPV subtype was HPV 18 in endometrial cancer. Some of the patients were detected to be positive for more than 2 subtypes of HPV. In 636 female patient with condyloma acuminatum, the infection rates of HPV6, HPV11 accounted for 44.97% and 29.40%, respectively, HPV 16 and/or HPV 18 infection constituted a small percentage. In a few cases, infection with more than 2 subtypes was detected.

CONCLUSIONCervical carcinoma including pre-cancerous lesion differs from condyloma acuminatum in dominate infectious subtype of HPV. The former is mainly associated with HPV 16 and HPV 18 infections, and the latter mainly associated with HPV 6 and HPV 11 infections. But in both of the above lesions, a mixed infection with more than 2 types may occur and make the pathological changes and clinical treatment more complicated. The early diagnosis and supervision of HPV infection may be of great value for improvement of prognosis and quality of life.

OBJECTIVETo investigate the protective effect and mechanism of Shenqi Compound on diabetic angiopathy modeled rats.

METHODSTotally 18 SD rats were randomized into 3 groups, i.e., the normal control group, the diabetic mellitus (DM) group, and Shenqi Compound group, 6 in each group. The DM rat model was established by feeding high-fat diet (to induce hyperlipidemia) +intraperitoneal injection of small dose streptozotocin (STZ). Shenqi Compound was given to rats in the Shenqi Compound group at the daily dose of 2 g/kg. Equal volume of normal saline was given to rats in the model group and the normal control group by gastrogavage. All treatment was lasted for 12 weeks. Then 2-D and ultrasonic integrated backscatter technique were used to evaluate structural and functional changes of abdominal aorta in the progression of diabetic macroangiopathy. The fibrosis degree of the aorta vessel and myocardium capillaries were observed by using HE and Masson trichrome staining. The tension of the aortic vascular ring was determined. The transforming growth factor beta (TGF-beta) mRNA expression was detected by real time PCR (RT-PCR). The protein expression of TGF-beta, collagen I, collagen III, connective tissue growth factor (CTGF), and phosphorylation P38 MAPK were detected by Western blot.

RESULTSCompared with the normal control group, abdominal aortic systolic inner diameter, diastolic inner diameter, Peterson elastic modulus, stiffness index, and backscatter integral significantly increased; the rangeability of integral backscatter and the extension coefficient of cross section significantly decreased in the DM group (all P < 0.05). After 12 weeks aforesaid indices were obviously improved in the Shenqi Compound group (P < 0.05). Results of HE and Masson staining showed that the fibrosis degree of the aorta vessel and myocardium capillaries was obviously alleviated in rats of the Shenqi Compound group (P < 0.05). Results of the aortic vascular ring tension showed that acetylcholine induced vasodilatation and maximum diastolic percent were obviously elevated in the Shenqi Compound group (P < 0.05). Compared with the normal control group, the mRNA expression of TGF-beta, and the protein expression of TGF-beta, collagen I, and collagen III, and phosphorylation of P38 MAPK all significantly increased in the DM group (P < 0.05). Compared with the DM group, the mRNA expression of TGF-beta, and the protein expression of TGF-beta, collagen I, and collagen III, and phosphorylation of P38 MAPK all decreased (P < 0.05).

CONCLUSIONSShenqi Compound could effectively improve the arterial function in diabetic marcoangiopathy and microvascular dysfunction. The mechanism might be due to the down-regulating the expression of TGF-beta, and further suppressing the phosphorylation of P38 MAPK, reducing the synthesis of collagen I and collagen III, therefore, ameliorating arterial and myocardial interstitial fibrosis.

Ligustrazine, one of the major effective components of the Chinese traditional medicinal herb Ligusticum Chuanxiong Hort, has been reported plenty of biological activities, such as protect cardiovascular and cerebrovascular, neuroprotection and anti-tumor, et al. Because of its remarkable effects, studies on structural modification of ligustrazine have attracted much attention. Ligustrazine synthetic derivatives reported in recent decades are mainly derived from four primary intermediates (TMP-COOH, TMP-OH, TMP-NH2, HO-TMP-OH). To explore the neuroprotection activitiy of ligustrazine intermediates, six ligustrazine intermediates (2, 5, 8, 11, 12, 13) were synthesized and their protective effects against CoCl2-induced neurotoxicity in differentiated PC12 cells were studied. The target compounds were prepared via different chemical methods, including oxidation, substitution, esterification and amidation without changing the structure nucleus of ligustrazine. Compared with TMP (EC50 = 56.03 micromol x L(-1)), four compounds (2, 5, 12 and 13) exhibited higher activity (EC50 < 50 micromol x L(-1)) respectively, of which, compound 2 displayed the highest protective effect against the damaged PC12 cells (EC50 = 32.86 micromol x L(-1)), but target compounds 8 and 11 appeared lower activity (EC50 > 70 micromol x L(-1)). By structure-activity relationships analysis, the introduction of carboxyl, amino to the side chain of ligustrazine and appropriately increase the proportion of ligustrazine may contribute to enhance its neuroprotective activity, which provides a reference for the design, synthesis and activity screening of relevant series of ligustrazine derivatives in the future.
