Objective To investigate the effect of the heroin addicts on rat's thyroid C cells, the secretion of calcitonin(CT) and serum FT_3, FT_4, TSH. Methods Adulthood 55 male SD rats were randomly divided into normal control group(NCG), saline control group(SCG) and heroin dependence group(HDG). Heroin-dependent rat models were set up by the way of subcutaneous injection of heroin and the thyroid glands were excised on the 10th, 17th, 24th, 31st, and 38th days after models were set up. Tissues were assessed by immunohistochemical SABC method, cell counting, image analysis method and chemiluminescence techniques. ResultCompared with the normal control group(NCG)and saliane control group( SCG), the immune staining intensity was weakened;the number of CT positive cells was reduced(P<0.05);the average gray value was significantly higher(P<0.05) and showed a gradual increase in the CT positive cells of heroin dependence group(HGD). The concentration of TSH in HDG was not statistically significant as compared with the NCG. The concentration of FT_3 in HDG decreased gradually on the 10th day and the 17th day as compared with the NCG.(P<0.05). The concentration of FT_4 in HDG increased gradually on the 24th day and the 38th day as compared with the NCG.(P<0.05). Conclusion During heroin dependence period, the number and functional of CT positive cells has decreased. The changes of concentration of FT_3 and FT_4 suggest that the function of thyroid gland has changed.

Objective: To investigate the effects of dendritic cells(DCs) loaded with tumor antigens on the proliferation and antitumor activity of tumor-infiltrating lymphocytes(TILs) from hepatocellular carcinoma (HCC) in vitro . Methods:DCs derived from the peripheral blood of patients with HCC were loaded with autologous tumor lysate(Tuly) to generate DC-Tuly and then the DC-Tuly was co-cultured with autologous TILs in low concentration of IL-2. TILs were counted, and the phenotypes of DCs and TILs were assayed by FCM and the cytotoxicity of TILs was determined with LDH method. The concentration of cytokines in TILs culture supernatant such as IFN-? and TNF-? was detected by ELISA . Results: The expression levels of CD1a, CD80, CD83,CD86, CD40, HLA-DR molecules on the DC-Tuly are notably increased( P

Objective To evaluate the molluscicidal effect of 2 kinds of shamingdan in lab. Methods Under constant temperature (25?1) ℃, the studies were carried out by using different concentrations(dosages) of molluscicide, shamingdan, in various methods of immersing, spraying and dusting power, and the molluscicidal effects were compared with 50% wettable powder of niclosamide ethanolamine salt(WPN). Results The 48-hour's LC_ 50(s) of 4% shamingdan granular formulation and 50% shamingdan soluble powder were 0.1752 mg/L and 0.2713 mg/L, respectively, which were similar to that of 50% WPN. In spraying and dusting powder experiment, the 7-day's LC_ 50(s) were 3.0418, 0.1623 g/m~2 and 2.8752, 1.1101 g/m~2, respectively, and the 50% shamingdan soluble powder was better than 4% shamingdan granular formulation and 50% WPN. Conclusions The molluscicidal effect of 2 kinds of shamingdan using immersing is better than that using spraying and dusting. The molluscicidal effect of the 50% shamingdan soluble powder is remarkably better than that of the 4% shamingdan granular formulation and 50% WPN.

With the aid of scientific research management information system, we established an in-formation management for the scientific research funds. The structure,function and application of the system were introduced in this paper.

OBJECTIVETo investigate the therapeutic effect of heating and bandage treatment for chronic lymphedema of extremities accompanied with erysipelas.

METHODSFrom March 2004 to March 2013, 80 patients with chronic lymphedema of extremities accompanied with erysipelas were analyzed retrospectively. The patients underwent heating treatment (42 degree centigrade) with infrared light machine made by Shanghai Ninth People's Hospital, 2 hours a day, 20 hours for a session. Bandage treatment was adopted after heating treatment. 1 or 2 sessions were performed for each patient every year. The erysipelas occurring frequency, patients subjective feeling, treatment sessions and elastic material usage was recorded during the follow-up period. The erysipelas occurring frequency was tested by the method of rank and inspection. SPSS 17. 0 was used for statistical analysis.

RESULTSAfter heating and bandage treatment, the occurrence frequency of erysipelas was obviously controlled (Z = 7.598, P = 0.000). Erysipelas was not occurred any more in 60 (75%)patients. Remarkable reduction of occurrence frequency of erysipelas caused by various reasons was showed after treatment. Primary and secondary lymphedema after treatment were compared with those before treatment respectively, showing statistical difference (Z = 3.417 and 5.009, P = 0.001 and 0.000). Most of patients felt better subjectively. The relapse rate of erysipelas and lymphedema was lower if keeping using elastic material to give more pressure on extremities after therapy.

CONLUSIONSHeating and bandage treatment can obviously reduce the occurrence frequency of erysipelas. It can improve the quality of patients' lives. Simultaneously, the subsequent elastic material pressure therapy is essential.

Objective To verify whether cervical vestibular evoked myogenic potential (cVEMP) can be used as an effective method to assess vestibular functions in diabetic rats ,we examined and analyzed cervical vestibular e-voked myogenic potential (cVEMP) in different duration diabetic rats and normal rats .Methods A total of 220 male SD rats were randomly divided into control group (n=20) and diabetes group (n= 200) .The diabetic rats were further divided into 4 ,6 ,8 ,10 ,and 12 week groups (40 rats each group) according to the diabetes duration . Diabetes was induced by STZ .The general situation ,ABR and cVEMP were conducted in all the groups .Results All diabetic groups appeared typical diabetic symptoms including polydipsia ,polyuria ,more food ,weight loss (P<0 .01) and blood glucose elevation (P<0 .01) .The threshold of ABR was significantly elevated (P<0 .05) in the 6 , 8 ,10 ,and 12 week diabetic group .Compared to the normal group ,the threshold of cVEMP was significantly elevat-ed in 8 week(53 .87 ± 11 .16 dB nHL) ,10 week(67 .00 ± 12 .74 dB nHL) ,12 week(67 .00 ± 9 .23 dB nHL) diabetes groups(P<0 .01) and the mean latency of P1 peak was significantly prolonged (P<0 .01) in 8 week(5 .01 ± 0 .33 ms) ,10 week(5 .37 ± 0 .45 ms) ,and 12 week(5 .39 ± 0 .24 ms) .The mean latency of N1 peak was significantly pro-longed (P<0 .01) in 10 week (8 .98 ± 0 .86 ms) ,and 12 week (9 .08 ± 0 .45 ms) compared to the control group .As to P1 - N1 amplitudes ,there was no significantly difference among all groups (P> 0 .05) .Conclusion In the cVEM P test ,the threshold increased ,the PI peak latency and N1 peak latency prolonged from the 8 th week of diabe-tes rats models .Vestibular functions were descent gradually due to different degrees of vestibular end -organ impairment . All data indicated that VEM P could be used as an early diagnostic method .

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.
