Objective To observe the clinical efficacy of Qingre Liangxue Recipe (QLR), a herbal prescription with the actions of clearing heat and cooling blood, for the treatment of gouty arthritis. Methods Sixty-five cases of gouty arthritis patients were randomly divided into treatment group (N=32) and control group (N=33). Both groups were given oral use of colchicine during the acute stage and being suspended when the pain was relieved, and then were given oral use of allopurinol tablets during the remission stage. Additionally, the treatment group was given oral use of QLR all through the acute stage and remission stage. The treatment lasted for 4 weeks in both groups. After treatment, clinical efficacy was evaluated in the two groups. The number of acute relapse cases and the changes of blood uric acid level were observed. Results At the end of the first treatment week, the treatment group had a total effective rate of 96.9%, significantly higher than that (81.8%) of the control group. At the end of the fourth treatment week, the treatment group had a total effective rate of 100.0%, significantly higher than that (90.9%) of the control group. The treatment group had better therapeutic effect than the control group at the end of the first or the fourth treatment week, the difference being significant ( P<0.01). The number of acute relapse cases and the serum uric acid level were lower in the treatment group than those in the control group during 4 treatment weeks or 12 weeks after treatment suspension, the difference being significant ( P<0.01). Conclusion QLR combined with anti-gout medicines can effectively relieve symptoms of gouty arthritis, reduce incidence of acute relapse, and have long-term effect on lowering blood uric acid level.

Objective To investigate the influence of acupuncture on promoting rat blastocyst nidation with Cx43 expression at the acupoints silenced, and to relate Cx43 with acupuncture's effects. Methods Ma-ted female rats were randomly divided into five groups: normal control, model, acupuncture, interference-control and interference. Mifepristone was used to induce a model of nidation disorder, and RNA interference technology was used to silence the expression of Cx43 at acupoints. P-Cx43-shRNA (1) was injected locally into the acu-points of rats in the interference group, and P-con-shRNA was injected in the interference-control group. Acu-puncture was administered to the acupuncture, interference-control and interference groups for 7 days. On the 8th day of pregnancy, the quality of blastocysts, pregnancy rates, and the average amount of blastocysts in each group were observed. Results ①The mRNA and protein level of Cx43 at the zusanli (ST36) acupoints in the interference group were significantly lower than in the acupuncture group ( P<0.05, P<0.01). There was no significant difference between the interference-control group and the acupuncture group. ② Compared with the normal control group, the quality of blastocysts in the model and interference groups was bad, and the amount was less. Their size was comparatively small, they were inhomogeneous, poorly distributed and had poor blood supply. The results improved in the acupuncture group and the interference-control group compared with the model group. ③The pregnancy rates in the normal control, model, acupuncture, interference-control and inter-ference groups were 100% , 50% , 75% , 75% , and 50% respectively, but these differences were not statisti-cally significant. ④The average amount of blastocysts in the model and interference groups was significantly less than in the normal group (P≤0.01). Compared with the acupuncture group, the average amount of blastocysts in the interference group was lower (P≤0.05). Conclusion Acupuncture can improve the quality and quan-tity of blastocysts in a rat model of nidation disorder. Local injection of Cx43 shRNA expression vector can si-lence the expression of Cx43 in acupoints and markedly influence acupuncture's effect. This demonstrated that Cx43 was involved in acupuncture's effects.

Objective To study the expression of Toll-like receptor-2 (TLR-2) and caspase-3 in the intestine of premature rats with necrotizing enterocolitis (NEC),and to explore the protective effects and possible regulatory mechanism of glutamine (Gln) in the NEC.Methods Sixty premature rats (gestational age 21 d) were divided into three groups (n = 20 each) according to the random number table: control group,model group and Gln intervention group.Rats in model group were given formula feeding,hypoxia and cold stress.Rats in Gln intervention group were given Gln 0.3 g/kg to the formula feeding,hypoxia and cold stress.All the premature rats were sacrificed and the intestine tissues were obtained on the third day after birth.The histological changes of ileal tissues were scored after HE staining.The expression of TLR-2 and caspase-3 in jejunum,ileum and colon were detected by inmunohistochemistry,and the expression of TLR-2 mRNA in jejunum,ileum and colon were detected by real-time fluorescence quantitative reverse transcription-polymerase chain reaction.Results Pathology score of ileum in model group,Gln intervention group and control group were 3.10 ±0.99,2.40 ± 0.69 and 0.30 ±0.48,respectively.The expressions of TLR-2 protein in ileum were 2.53±0.94,2.15±0.82 and 1.57 ± 0.62 in the three groups respectively,and the expression of caspase-3 protein were 2.83 ± 0.45,2.70 ± 0.04 and 0.91 ± 0.29.The content of TLR2 mRNA in model group was 1.46 times higher than that of Gln intervention group and was 2.10 times higher than that of control group.Compared with the control group,the pathology score,expression of TLR-2 and caspase-3 protein,and TLR-2 mRNA in model group were significantly higher,P＜0.01.However,compared with the model group,those changes were improved in Gln intervention group,P＜0.05.Expression of TLR-2 mRNA positively correlated to the expression of caspase-3 protein (r=0.71,P＜0.01) and pathology score (r = 0.69,P＜ 0.01).Expression of caspase-3 protein positively correlated to the intestine injury pathology score (r=0.81,P＜0.01).Conclusions TLR-2 may be involved in the pathogenesis of NEC.Gln might reduce the expression of TLR-2 in the intestine,and decrease the apoptosis of intestinal epithelial cells to protect the intestine of preterm birth rats.

Objective To investigate the effects of laporoscopic resection applied to colorectal cancer patients on metabolism. Methods According to patients' choice of operation, either laparoscopic-assisted (n = 22, experimental group) or open(n = 27, control group) resection of colorectal cancer was performed. The levels of electrolyte were assayed preoperatively, postoperatively and on the time of 24 hours after opera-tion. Rseults There was no significant difference in the level of electrolyte before operation between the two groups (P > 0. 05). Compared with the preoperative period, the level of serum potassium in the both groups were significantly increased after operation(P < 0. 05), and 24 hours later, the levels of electrolyte was not significantly different in both the two groups (P > 0. 05). During the postoperative period, the level of serum potassium in the experimental group was lower than the control group(P <0. 05), while the level of HCO_3~- was higher than the control group(P <0. 05), and there were no significant differences in the level of serum sodium, chloride and calcium between the two groups(P > 0. 05). Conclusions Laparoscopic-assisted re-section of colorectal cancer gives lower levels of stress responses compared to open surgery. However, it shows higher effect on the level of HCO_3~- , and must be paid more attention during operative and postopera-tive period.
