The content of the asarone submicro emulsion injection was determind by HPLC method, and thereby a quality evaluation method was established based on indexes of pH value, particle size, peroxide value, methoxy aniline values, free fatty acid, lysophosphatidylcholine, visible foreign substances, insoluble particle, sterility, bacterial endotoxin and impurities, etc. The results showed that the injection exhibited uniform physical appearance and all the products were in milkwhite liquid. The content of the three batches products were respectively 102.9%, 100.8%, 97.70% of the labeled amount, with mean particle size of 210-250 nm, and other indexes all met with the standards. The reserved samples showed no obvious change in terms of detection indexes and indicated good stability after the accelerated stability test and long-term stability for 12 months. The quality evaluation method established in this study could be applied to quality control and stability investigation of asarone submicron emulsion injection, which laid a basis for further clinical research and application.

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 explore the influence of fluorine on mRNA and protein expression of the insulin-like growth factor-1 (IGF-1) and its receptor of rat osteoblasts.Methods Osteoblasts were isolated from rat bone by enzyme digestion.Different fluorine concentration [0 (control),10-7,10-6,10-5,10-4,10-3 mol/L] was add to the second generation osteoblasts.The IGF-1 in the culture medium was determined by radioimmunoassay (RIA) at different fluorine concentration and different time (24,48 h).The expression of IGF-1 receptor was measured by the method of fluorescent quantitation PCR and the expression of protein IGF-1 receptor was measured by Western blotting.Results ①With increased dose of fluoride exposure,IGF-1 concentration in the osteoblastic culture medium increased first and then decreased at 24,48 h,respectively.Compared to the control group [(38.83 ± 3.48)ng/L],IGF-1 concentration of the 24 h 10-6 mol/L group[(65.45 ± 4.84)ng/L] was higher,and the difference was statistically significant(P ＜ 0.05).The same result was also shown in the 48 h 10-5 mol/L group [(59.14 ± 1.53)ng/L] to its corresponding control group [(33.79 ± 1.84)ng/L,P ＜ 0.05].②The mRNA expression of IGF-1 receptor of the 24,48 h 10-5 mol/L groups (0.0055 ± 0.0004,0.0262 ± 0.0040) was significantly higher than their corresponding control groups (0.0022 ± 0.0001,0.0073 ± 0.0008,all P ＜ 0.05).③With increased dose of fluoride exposure,the protein expression of IGF-1 receptor increased first and then decreased ;the expression of 24 h 10-5 mol/L group (1.39 ± 0.16) was compared with the corresponding control group (0.86 ±0.12),and the difference was statistically significant (P ＜ 0.05) ; the expression of 48 h every fluorine group was also compared with the corresponding control group,and the difference was not statistically significant(all P＞ 0.05).Conclusions Fluorine can affect the mRNA and protein expression of osteoblastic IGF-1 and its receptor.It indicates that IGFS signal transduction pathways play an important role in fluorine regulation of bone metabolism.

OBJECTIVETo evaluate the application of side-to-side anastomosis of the lesser curvature of stomach and jejunum in laparoscopic Roux-en-Y gastric bypass (LRYGB).

METHODSClinical data of 29 patients with type 2 diabetes mellitus (T2DM) undergoing side to side anastomosis of the lesser curvature of stomach and jejunum in LRYGB from May 2012 to November 2012 in Department of General Surgery, Beijing Tiantan Hospital, Capital Medical University were analyzed retrospectively.

RESULTSAll the procedures were successfully completed without conversion to laparotomy. The side-to-side anastomosis of the lesser curvature of stomach and jejunum avoided the laparoscopic suture. No gastrojejunostomy anastomotic bleeding, fistula, obstruction and other complications occurred after operation and no complications of gastrojejunostomy anastomosis were found during a follow up of 1 to 7 months.

CONCLUSIONSSide-to-side anastomosis of the lesser curvature of stomach and jejunum in LRYGB can manipulate the size of anastomosis accurately and avoid the laparoscopic suturing. It is simple and easy to learn.

OBJECTIVETo observe the effect of recombinant human erythropoietin (rHuEPO) on immune function of premature rats.

METHODSRHuEPO of 250 IU/(kg.t) or 500 IU/(kg.t) was administered to premature rats every other day for nineteen days. The control premature rats were received normal saline. The changes of hemoglobin (Hb), serum erythropoietin (EPO), red blood cell (RBC) immune function, T lymphocyte proliferative responsiveness, and production of tumor necrosis factor alpha (TNF-alpha) were observed.

RESULTSPremature rats showed lower levels on Hb, RBC immune function, T cell responsiveness and production of TNF-alpha compared with mature rats at birth. The postnatal declines of Hb and RBC immune function were lessened in the treated groups of premature rats, the higher dosage group of 500 IU/(kg.t) was more significant than the lower dosage group of 250 IU/(kg.t). When experiments were over, Hb of control premature rats was (7.72 +/- 0.89) g/dl, Hb of premature rats received 500 IU/(kg.t) was (10.08 +/- 0.90) g/dl (P < 0.01). C3b-R% of control premature rats was (11.00 +/- 0.95)%, C3b-R% of premature rats received 500 IU/(kg.t) was (17.75 +/- 1.04)% (P < 0.01). IC-R% in control premature rats was (12.83 +/- 1.33)%, IC-R% of premature rats received 500 IU/(kg.t) was (10.50 +/- 1.67)% (P < 0.01). The postnatal rise of T cell responsiveness and the production of TNF-alpha in premature rats increased in the treated groups, which was more significant in the higher dosage group of 500 IU/(kg.t) than in the lower dosage group of 250 IU/(kg.t). The OD index of control premature rats was 0.159 +/- 0.014, the OD index of premature rats received 500 IU/(kg.t) was 0.354 +/- 0.050 (P < 0.01). TNF-alpha in control premature rats was (0.270 +/- 0.014) ng/ml, TNF-alpha of premature rats received 500 IU/(kg.t) was (0.415 +/- 0.010) ng/ml (P < 0.01).

CONCLUSIONS(1) Premature rats had lower RBC immune function and T cell responsiveness and underproduction of TNF-alpha at birth. (2) Premature rats had an improvement with the RBC immune function after rHuEPO administration. (3) Premature rats had improvements with T cell responsiveness and TNF-alpha after rHuEPO administration, and there was a positive correction between the RBC immune function and T cell responsiveness with the production of TNF-alpha.
