AIM\ To observe the effect of methionine enkephalin(Met Enk) on proliferation and mechanism involved by opiate receptor of peripheral blood lymphocyte(PBL) from patients with systemic lupus erythematosus(SLE). METHODS\ Lymphocyte proliferation assay. RESULTS\ Naloxone (Nal,1?10 -6 mol?L -1 )could block the increasing effect of Met Enk(1?10 -8 ～1?10 -6 mol?L -1 )on the PBL proliferation of normal humans,but there was no direct effect on that. However,Nal could not only block the promotive action of Met Enk on PBL proliferation of SLE patients,but there was a direct decreasing effect on it. CONCLUSION\ Endogenous Met Enk may participate in the abnormal regulation with SLE PBL via opiate receptor.

Objective To evaluate the efficacy of itopride hydrochloride combined with alpha-lipoic acid in treatment of diabetic gastroparesis.Methods One hundred and ten patients with diabetic gastroparesis were randomly assigned to two groups.Sixty patients received α-lipoic acid plus itopride (α-lipoic acid 0.6 g intravenously for 14 d plus itopride 50 mg orally t.i.d), and 50 cases received oral itopride only.The clinical symptoms including postprandial abdominal fullness, belching, acid reflux, anorexia, nausea and vomiting were observed;the gastric emptying rate was tested, and plasma motilin and serum ganstrin levels were measured groups, before and after two weeks of treatment.Results The clinical symptom scores of combination therapy group (4.62 ± 3.46 vs.12.26-± 3.43) and control groups (5.43-± 3.65 vs.12.31-± 3.37) were improved after treatment.The overall effective rate of combination group was 91.6％ and that of itopride therapy group was 78.0％ (x2 =4.098, P ＜ 0.05).Gastric emptying rate of combination group [(76.9 ± 9.7) ％ vs.(37.3 ± 10.2) ％] was increased more markedly than that ofitopridegroup[(57.2-± 10.4)％ vs.(36.8-± 11.2)％] (t =10.221, P ＜0.05).Plasma motilin and serum ganstrin levels in combination group [(640.2 ± 64.4) ng/L vs.(554.0 ± 67.6) ng/L, (152.6 ± 20.3)ng/L vs.(96.8 ± 22.2)ng/L] were reduced more markedly than those in itopride group [(636.3 ±66.4)ng/L vs.(589.4 48.3)ng/L, (153.5-± 19.4) ng/L vs.(120.9 ± 19.7)ng/L] respectively (t =3.100, 5.959, all P ＜ 0.05).Conclusion For patients with diabetic gastroparesis, α-lipoic acid and itopride combination therapy can significantly improve symptoms and gastric emptying rate, decrease motlin and gastrin levels;and the efficacy of combination therapy is better than that of itopride monotherapy.

With the development of functional genomics, high throughput analysis of genes’ function has been the mainstream of research, and exogenous gene's over expression via Agrobacterium-mediated transformation is the most commonly used method in gene functional analysis.The versatile plant expression vector cassette named pBHT-5 was constructed by the method of site-specific mutagenesis based on pBI121. First of all, the restriction enzyme SfiI recognition site in trfA gene (X00713) which was relevant to plasmid replication and stability was replaced without changing its amino acid composition. And then the SfiIA,SfiIB sites were added between promoter CaMV35s and terminator NOS. The versatile plant expression vector cassette can be directly used to construct plant expression vector containing the full-length genes cloned by Clontech SMARTTM technology, which will raise the efficiency of vector construction. The result will provide basis of new genes’ high throughput screening and functional analysis, then get the new genes functioning in plant osmotic stress resistance.

Objective To evaluate the efficacy of 10-day compound allantoin containing quadruple regimen in the treatment of chronic gastritis with Helicobacter pylori (H.pylori) infection,and to compare with the bismuth-containing quadruple therapy.Methods Altogether 173 patients with H.pylori positive chronic gastritis confirmed by gastric endoscope were divided into 10-day compound allantoin containing quadruple regimen group (n =43),24-day compound allantoin containing quadruple regimen group (n =46),10-day bismuth-containing quadruple regimen group (n =42) and 24-day bismuth-containing quadruple regimen group (n =42).After the treatment,the eradication rate of H.pylori,the rate of gastrointestinal symptoms (epigastric pain,bloating and belching) relief and the adverse effects of each group were observed.Intention-to-treat (ITT),per-protocol (PP) statistical analysis and chi-square analysis were performed for statistical analysis.Results H.pylori eradication rates of 10-day compound allantoin containing quadruple regimen group,24-day compound allantoin containing quadruple regimen group,10-day bismuth-containing quadruple regimen group and 24-day bismuth-containing quadruple regimen group analyzed by ITT were 90.7％ (39/43),91.3％ (42/46),90.5％ (38/42) and 88.1％ (37/42),respectively; while analyzed by PP were 90.7％ (39/43),93.3％ (42/45),90.5％ (38/42) and 90.2％ (37/41),respectively.And there were no statistical differences between groups (all P＞0.05).Ten days after the treatment,the rates of epigastric pain relief of 24-day compound allantoin containing quadruple regimen group and 24-day bismuth-containing quadruple regimen group were 81.1％ (30/37) and 78.8％ (26/33),respectively,the rates of bloating relief were 82.4％ (28/34) and 71.0％ (22/31),respectively,and the rates of belching relief were 76.9％ (20/26) and 75.0％ (21/28),respectively.There were no statistical differences between the two groups (all P＞ 0.05).However after 24-day treatment,the rates of epigastric pain relief of 24-day compound allantoin containing quadruple regimen group and 24-day bismuth-containing quadruple regimen group were 91.9 ％ (34/37) and 87.9％ (29/33),respectively,the rates of bloating relief were 94.1％ (32/34) and 87.1％ (27/31),respectively,and the rates of belching relief were 96.2％ (25/26) and 85.7％ (24/28),respectively.There were no statistical differences between the two groups (all P＞0.05).And the rates of epigastric pain and bloating relief increased after 24-day treatment compared with those of 10-day treatment,however the differences were not statistically significant between the two groups (all P＞ 0.05).In 24-day compound allantoin containing quadruple regimen group,the rate of belching relief was higher after 24-day treatment compared with that of 10-day treatment,and the difference was statistically significant (x2=4.127,P=0.042).No severe adverse effects were observed in each group,and there were no adverse effects such as oral metal odor,tongue black and melena in compound allantoin containing quadruple therapy.Conclusions Ten-day compound allantoin containing quadruple therapy as first-line approach in the treatment of chronic gastritis with H.pylori infection can get better H.pylori eradication and the efficacy is similar to bismuth quadruple therapy.Meanwhile the symptom relief rate is high and no obvious adverse effects were found.

ObjectiveTo make sure the factors of influencing supply and utilization rehabilitation service of hospitals in Beijing.MethodsFive grade A hospitals in different districts in Beijing were surveyed to realize the condition and factors of influencing supply and utilization of rehabilitation service in polyclinics in Beijing and make sure the developing situation of departments of rehabilitation medicine, and its restriction factors in their hospitals.ResultsThe departments of rehabilitation medicine in the five hospitals had not reached to requirement of administer criterion to comprehensive hospitals, issued by Ministry of Health. The factors of influencing supply and utilization of rehabilitation service in polyclinics in Beijing included: discordant cooperation between rehabilitation section and other sections in hospitals; leaders of hospitals and clinical personnel not understanding the importance of rehabilitation early intervention much; patients and their family not understanding the special curative effect to prevent and treat disability of rehabilitation; the application for reimbursement limitation to the fee for patients to accept rehabilitation treatment and/or stay in rehabilitation section in hospitalization insurance and plan as a whole, and so on.ConclusionThe factors above limit the further development of rehabilitation service of polyclinics in Beijing. Effective measures should be taken and correlative policies should be established in order to promote the rehabilitation service in Beijing.

Abstract: Objective　A survey on the plague foci in Qiaojia County of Jinsha River Basin was conducted to understand the composition of plague host vectors and the prevalence of plague among animals, to explore the occurrence and epidemic risk of plague, and to provide scientific basis for plague monitoring and control in this area. Methods　Seven villages and towns in Qiaojia County were selected as the research areas, and the cage night method and the clamp line method were used to investigate the small mammals and their surface parasitic fleas. The host animal organs, serum and surface parasitic flea's samples were collected. The plague indicator animal serum was collected simultaneously on the spot, and the collected host animal organs and flea's samples were cultured and detected for Yersinia pestis. The indirect hemagglutination test (IHA) was used to detect the fraction 1 capsular antigen (F1) antibody of the host animal and the indicator animal serum samples. Results　A total of 525 small mammals belonging to 3 orders, 6 families, 12 genera and 23 species were captured. The dominant species in farming areas were Apodemus chevrieri (31.05%), Niviventer confucianus (13.90%) and Anourosorex squamipes Milne-Edwards (11.43%). The dominant species in residential areas were Rattus norvegicus (66.67%) and Rattus tanezumi (20.00%). The rat densities in agricultural and residential areas were 20.98% and 1.00%, respectively. A total of 277 external parasitic fleas belonging to 15 species, 13 genera, 5 families were collected. The dominant species were Palaeopsylla remota (22.02%), Neopsylla specialis specialis (20.58%), Frontopsylla diqingensis (18.77%) and Ctenophthalmus (Sinoctenophthalmus) quadratus (11.55%), and the rat fleas index was 0.53. No Yersinia pestis was isolated from all rodent organs and flea samples. A total of 167 serum samples from dogs and 15 serum samples from rats were collected, and plague F1 antibody was detected by IHA. IHA detection of plague F1 antibody were negative. Conclusions　Qiaojia County has the distribution of the main host and main vector of plague, and the rat density is high, but the rat body flea index is low. There is no positive detection of plague host animals, vector fleas and indicator animals. It can be considered that the risk of plague occurrence and epidemic in the region is not high in the near future. It is necessary to further strengthen the monitoring and control of plague and other rodent-borne diseases in the region.
