Objective To establish a methodological study pattern of quantitative analysis of multi-components by single marker ( QAMS) , and examine its feasibility and technical applicability in the quality control of compound preparation of traditional Chinese medicine-Jinhoujian spray. Methods Gas chromatographic method ( GC) was used and naphthalene served as the internal standard. Menthol was used as the reference substance. The relative correlation factors ( RCF) of 1,8-Cineole, camphor and borneol to menthol were calculated and established to carry out QAMS.The accuracy of this method was confirmed by comparison of internal standard method. Results The reproducibility of relative correction factor was perfect. The two methods did not show significant difference in 10 bathes of samples. Conclusion The QAMS method is feasible, credible, and can be used to determine active ingredients in Jinhoujian spray.

Objective:To explore bromodomain and extra-terminal (BET) inhibition in the regulation of vascular endothelial cells activation and early atherosclerosis formation and its potential molecular mechanisms.Methods:1.Human umbilical vein endothelial cells (HUVEC) and mouse heart endothelial cells (MHEC) were isolated,and tumor necrosis factor α (TNFα) was used to activate in flammatory genes transcription in the presence or absence of JQ1,a specific BET inhibitor.The groups are as follows:(1)Normal control group;(2) TNFα(25 ng/mL)group;(3) TNFα+JQ 1 group.The gene mRNA and protein expression of inflammatory cytokines were measured by both real-time PCR and flow cytometry (FCM).2.LDL receptor-deficient (LDLR-/-) mice were randomly divided into 2 groups:JQ1 group (n=8,JQlintraperitoneal,50 mg/kg,daily) and control group (n=8,DMSO,daily).After 8 weeks feeding with high cholesterol diet,vascular cell adhesion molecule-1 (VCAM-1) expression in aortic arch was measured by immunohistochemistry.The activity of nuclear factor kappa B (NF-κB) signaling was monitored by 5XκB luciferase reporter assay in HEK293.Results:TNFα dramatically induced the mRNA and protein expression of inflammatory genes and JQ 1 significantly downregulated the induction of them (E-selectin,P-selectin,VCAM-1,IL-8)(P＜0.01).Immunohistochemistry detection indicated that JQ1 significantly downregulated the expression of VCAM-1 in aortic arch induced by 8 weeks high cholesterol diet feeding comparing to control group.In addition,BET bromodomain inhibition downregulated TNFα upregulated NF-κB transcriptional activity (P＜0.01).Conclusions:Our study demonstrated that BET bromodomain was involved in NF-κB mediated inflammatory genes expression;inhibition of BET bromodomain suppressed vascular endothelial activation in vitro,and attenuated early atherogenesis in vivo.

OBJECTIVETo study curative effect of chronical hepatitis B with treatment of integrative traditional Chinese and western medicine.

METHOD115 cases of HBeAg and/or HBVDNA positive chronical hepatitis B were randomly divided into two groups in control. The first group treated by traditional Chinese medicine (TCM)-Fufang Huangqi granule and the second treated by intergrative traditional Chinese and western medicine (ICWM)-Fufang Huangqi granule and lamivudine for at least 24 weeks.

RESULTThe positive rate of HBVDNA at 12, 24 weeks, and the positive rate of HBeAg at 24 weeks in TCM are markedly lower than those of before treatment (P < 0.01). The positive rate of HBeAg and the positive rate of HBVDNA in ICWM are markedly lower than those of before treatment both at 12, 24 weeks (P < 0.01). The average values of HBVDNA are markly lower than before treatment in two groups at both 12,24 weeks (P < 0.01). At 12 weeks, the negative-turning rate of HBVDNA in the ICWM group is 79.17%, which shows significant difference in comparision with 40.00% in the TCM group (P < 0.01). The negative-turning rate of HBeAg in the ICWM group is 26.92%, which shows no significant difference in comparision with 32. 08% in the TCM group. At 24 weeks, the negative-turning rate of HBVDNA in the ICWM group is 85.71%, which shows significant difference in comparision with 50.00% in the TCM group (P < 0.01). The negative-turning rate of HBeAg in the ICWM group is 36.36%, which shows no significant difference in comparision with 28.57% in the TCM group. At 12 weeks,the total effective rate of the ICWM group is 96. 43%, which shows significant difference in comparision with 71.26% in the TCM group (P<0.01). At 24 weeks, the total effective rate of the ICWM group is 88. 00%, which shows significant difference in comparision with 67.61 % in the TCM group (P < 0.01). The average values of ALT and AST are markly improved than those of before treatment in two groups (P < 0.01). The average values of ALB is markly higher than before in TCM groups after 24 weeks treatment (P < 0.01).

CONCLUSIONFufang Huangqi granule integrated with lamivudine possesses a better effect for counteracting the hepatitis B virus and improving the liver functioin than only itself.

Objective To seek a rational method of estimating the demands for medical services so as to work out regional health planning in a scientific way. Methods A metropolis including 19 counties and districts was selected as a region and demands for medical services were forecasted via retrospective analysis and the econometric model. Results A model of the demands for outpatient and inpatient services was obtained based on the impact of many social and economic factors on medical health services, and illustrations were given to indicate the demands for medical health services in the 19 counties and districts in future when prices should rise by 15% and 20%. Conclusion The econometric model can be used as a tool for estimating the demands for medical health services, and yet improvements need to be made.

Objective To evaluate the indications and intraoperative management of nephron-spar- ing surgery (NSS) for renal cell carcinoma (RCC).Methods A total of 53 patients (32 men and 21 women;age range,21 -76 years) with unilateral RCC and a normal contralateral kidney underwent NSS.The disease course ranged from 1 week to 13 months.The unilateral RCCs were detected by B-uhrasonography. Partial nephrectomy was performed on 38 cases of polar RCC and wedge nephrectomy was performed on 15 cases of central RCC.Both renal vein and artery were blocked for 10 - 15 min,and unclamped for 1 -2 min if necessary.The resections were finished within 7 -21 min (mean,12 min).No inosine and regional hypo- thermia were used during operation.Absorbable hemostatic gauze and terylene flake were used to suture renal wound surface.After operation all patients were treated with interferon hypodermic injection of 5 000 000 U every other day for 3 months.Results The diagnosis of RCC with negative cutting margin was confirmed by pathological examination in all patients.The greatest dimension of the renal cancers were＜4 cm except for one of 6 cm.The clinical stage was T_1N_0M_0 in all patients.During the follow-up of 6 -48 months,all pa- tients were alive without recurrence and had normal renal function.Conclusions NSS can be rapidly per- formed for T_1 stage renal cancer＜4 cm or single clearly localized cancer＞4 cm in diameter.The follow-up results are satisfactory.

Nucleobindin2protein(NUCB2)isanewlydiscoveredneuropeptideprecursorprotein, which has a comprehensive cytology function and is expressed in the hypothalamus nucleus and many peripheral tissues.There aren′t many studies about its signaling pathway,where neuroendocrine regulation,cell survival growth,tumor suppressor,cytokine secretion were found to involve in it.Besides,it has also been confirmed that breast cancer,lung cancer,ovarian cancer and prostate cancer are closely related to NUCB2.Therefore, several downstream pathways of NUCB2 may be related to the formation and progression of tumor.Further stud-ies are still needed to clarify the signal pathways of NUCB2 to provide a reliable basis for clinical cancer preven-tion.

Objective To investigate the diagnostic value of MRI in the infantile developmental dislocation of the hip.Methods Forty-five cases of preoperative hip MRI data of DDH (patient group)and 40 cases of normal hip (control group)MRI data were retrospectively analyzed.Three types were classified according to the standard of Dunn.Then the bony acetabular index (BAI),cartilaginous acetabular index (CAI)were measured on coronal MRI and all the intra-articular structures (articular cartilage,labrum, teres ligament and iliopsoas)in the acetabulum that impeded the reduction of the femoral head were observed.Results There were normal hips (80 hips)and dislocated hips (73 hips).In dislocated hips typeⅠ (30 hips),typeⅡ (20 hips),and typeⅢ (23 hips) were found.The values of BAI were (26.13±2.19)°and (35.87±4.42)°,CAI (13.84±1.07)°and (21.92±4.70)°for patient group and control group.The values of BAI were (31.80±1.74)°,(37.80±3.40)°and (39.17±4.11)°,CAI (17.20±2.68)°,(20.91±2.02)°and (27.50±2.78)°for the typesⅠ,Ⅱ,Ⅲ respectively.Differences of BAI and CAI between patient group and control group were showed (t=-11.048 and -9.188,P =0.000).Statistically significants were found among the typeⅠ,Ⅱ,Ⅲ(F=22.159 and 47.241,P =0.000).There were linear correlations for patient group ,control group,and the typeⅠ,Ⅱ,Ⅲ (r= 0.964,0.844,0.953,0.931 and 0.870,P =0.000).Some pathological changes such as varus labrum,thick teres ligament,iliopsoas spasm,articular cartilage hyperplasia,fat hyperplasia,joint effusion were observed in the type Ⅱand Ⅲ.Conclusion MRI is not only used for measuring the values of BAI and CAI,and a linear correlation among all kinds of DDH,but also some factors hindering the reduction of the femoral head can be found clearly.It can provide an important reference basis for the diagnosis and treatment of DDH.

Objective To investigate the influence of total progressively motile sperm count(TPMSC) after treatment on clinical outcomes of intrauterine insemination(IUI) with the husband′s sperm in ovulation-promoting cycles.Methods The clinical data in 4179 cases undergoing IUI with the husband′s sperm in ovulation-promoting cycles were retrospectively analyzed.The correlation between clinical pregnancy rate and TPMSC was analyzed.Results Among all the clinical data,TPMSC was to 100×106 in occasional live sperm.TPMSC<0.15×106 was in 15 cases,1 case had pregnancy (live sperm was occasionally seen on IUI day after sperm processing).Ten cases of TPMSC >60×106 had no pregnancy.A total of 4 154 cases of TPMSC (0.15-60.00)×106 were analyzed.The female age,duration of infertility,number of follicles and endometrial thickness(EDM) had no statistical differences among various groups.The clinical pregnancy rate was 13.5%(576/4 154),the group with the highest clinical pregnancy rate was (5.00-<10.00)×106.But there was no statistically significant difference in clinical pregnancy rate among groups(P=0.133).Conclusion Performing IUI in PMSC (0.15-60.00)×106 after processing can get preferable pregnancy rates.

Objective To evaluate the effect of rehabilitation nursing with movement getting out of bed in early period after operation on the patients undergone the total hip replacement (THR).Methods The rehabilitation nursing was performed to 47 patients undergone THR including movement getting out of bed in early period; prepared sufficiently pre-operatively (evaluation and rehabilitation training); avoided the complications post-operatively; monitored the vital signs; trained standardizely; relieved pain sufficiently; took off the tubing as early as possible; rehabilitated with the walking aid.Results None had DVT, dislocation, fracture around the prosthesis, infections, death etc, all patients got out of bed in the 1st day after operation, the average time in hospital was 19 days, and the average Harris scores were 54.26, 62.55, 73.58, 91.17 and 93.35 at pre-operation, and in 14th day, 1st month, 3rd month and 6th month post-operation respectively.Conclusion Rehabilitation nursing with early movement getting out of bed to exercise after THR operation can promote the recovery of the hip function, reduce the complications, shorten the hospital stay.
