2.The relation between Helicobacter pylori infection and the amount of interleukin-8 and granulocyte clolny-stimulating factor
Chinese Journal of Digestive Endoscopy 2001;0(01):-
Objective To evaluate the relationship between Helicobac ter pylori (Hp) related gastritis and gastric mucosa content of interleukin - 8 (IL-8) and granuloeyte colony-stimulating factor ( G-CSF). Methods ELISA was used to detect the amount of IL-8 and G-CSF in supernate fluid of gastromucosal tissue culture from 60 patients, and to examine the difference between Hp infected and non-Hp infected cases. These 60 cases include normal gastric mucosa (n =20) , chronic gastritis mucosa (n = 14) , gastric ulcer mucosa (n = 13) , duodenal ulcer mucosa ( n = 13 ). Results The amounts of IL-8 and G-CSF in cases with Hp infection were significantly higher than those without infection (P

Objective It has been shown that ketamine can effectively suppress expression of cell adhesion molecules in vitro. The purpose of this study was to investigate the effect of ketamine on plasma adhesion molecules in vivo during cardiac valve replacement.Methods Twenty ASA Ⅲ-Ⅳ patients (7 males, 13 females) aged 23-65 yrs, weighing 31-77 kg undergoing cardiac valve replacement were randomly divided into two groups of 10 patients each : ketamine group received ketamine 2 mg?kg-1 i.v. before induction of anesthesia and at the start of CPB and control group received normal saline instead of ketamine. Blood samples were taken from radial artery for determination of plasma P-selectin, L-selectin, ICAM-1, IL-6 and cTnI concentrations before induction of anesthesia (T0 ,baseline) , 20 min after initiation of CPB (T1) , 30 min after aortic declamping (T2) 4 h and 24 h after CPB (T3, T4) . Results There was no significant difference between the two groups in age, weight, operation time, CPB time and aortic cross-clamping time. The concentrations of P-selectin, L-selectin, ICAM-1 and IL-6 at T1-4 and cTnI at T2-4 increased significantly compared to baseline (T0) in both groups ( P

Two isomers of nitrochlorobenzene (o-, and p-NCB) were treated by a Pd/Fe catalyst in aqueous solutions through catalytic amination and dechlorination. Nitrochlorobenzenes are rapidly converted to form chloroanilines (CAN) first through an amination process, and then rapidly dechlorinated to become aniline (AN) and Cl(-), without the involvement of any other intermediate reaction products. The amination and dechlorination reaction are believed to take place predominantly on the surface site of the Pd/Fe catalysts. The dechlorination rate of the reductive degradation of the two isomers of nitrochlorobenzene (o-, and p-NCB) in the presence of Pd/Fe as a catalyst was measured experimentally. In all cases, the reaction rate constants were found to increase with the decrease in the Gibbs free energy (correlation with the activation energy) of NCBs formation; the activation energy of each dechlorination reaction was measured to be 95.83 and 77.05 kJ/mol, respectively for o- and p-NCB. The results demonstrated that p-NCBs were reduced more easily than o-NCBs.

OBJECTIVETo compare the clinical therapeutic effects on intractable facial paralysis among acupuncture, acupoint catgut embedding and PDS embedding.
METHODSTwo hundred and seventy-nine patients of intractable facial paralysis were randomized into an acupuncture group, a catgut embedding group and a PDS embedding group, 93 cases in each one. Cuanzhu (BL 2), Yuyao (EX-HN 4), Taiyang (EX-HN 5), Xuanlu (GB 5), Dicang (ST 4), Jiache (ST 6), Quanliao (SI 18), Qianzheng (Extra), Xiaguan (ST 7) and Fengchi (GB 20) on the affected side and bilateral Hegu (LI 4) and Zusanli (ST 36) were selected in the three groups. In the acupuncture group, acupuncture was applied to those acupoints, once every two days; 10 treatments made one session; the successive three sessions were required. In the catgut embedding group and the PDS embedding group, catgut and PDS were embedded separately, once every 10 days; 3 treatments made one session and the successive two sessions were required. The therapeutic cycle was 2 months in the three groups. The therapeutic results were analyzed statistically 2 months later. The scores of Sunnybrook facial nerve grading system and the facial nerve electroneurography (ENoG) were used for the efficacy assessment before and after treatment in the three groups.
RESULTSAfter treatment, the score of Sunnybrook facial nerve grading system was improved apparently after treatment as compared with that before treatment in any of the three groups (all P < 0.05). The score in either of the embedding groups was better than that in the acupuncture group (both P < 0.05). The difference was not significant between the catgut embedding group and the PDS embedding group (P > 0.05). After treatment, ENoG wave ampli tude values in the frontal muscle and orbicularisoris muscle on the affected side were improved as compared with those before treatment in the three groups (all P < 0.05). Those in the catgut embedding group and the PDS embedding group were better than those in the acupuncture group (all P < 0.05), and had no significant difference as compared with those on the healthy side (P > 0.05). In the acupuncture group, ENoG wave amplitudes on the affected side were lower than those on the healthy side (both P < 0.05).
CONCLUSIONAcupuncture, catgut embedding and PDS embedding at acupoints all achieve the therapeutic effects on intractable facial paralysis. However, the acupoint embedding therapy presents more advantages on the recovery of facial nerve function. The efficacy is similar between the catgut embedding and the PDS embedding.

Objective To investigate the clinical effect of azithromycin on ankylosing spondylitis (AS). Methods Sixty-four AS patients with active disease were enrolled in this study. Among them, thirty-two AS patients (treatment group)received Azithromycin treatment at a dose of 0.5 g once a day for a period of 5~7 days , and another thirty-two patients receiving conventional treatment served as control (control group). BASDAI, CRP and ESR served as the disease activity evaluation index. Results Activity indexes in two groups of in the first 4~ 20 weeks of the treatment were decreased compared with those before the treatment (P < 0.05), while a rise was found in the 20 ~ 24 week and activity indexes gradually returned to pretreatment levels. At 0 ~ 16 weeks , the disease activity index of treatment group was below normal levels but that of control group was higher than the normal level with significant difference (P < 0.05). Conclusion The treatment of Azithromycin can control the disease activity of AS in the long term, which would be a new proposal in AS treatment.
