AIM: To clarify the effect of the specific sodium-hydrogen antiporter HOE642 on ischemia/reperfusion(I/R) injury including apoptosis, and the relationship between its effect and the time of HOE642 administration. METHODS: The isolated rat heart model were randomly divided into group A and B. Furthermore, the rat hearts in group A were divided into four subgroups including I/R, HOE-Pr+I/R, HOE-Is+I/R and HOE-Re, also the rat hearts in group B were divided into the following subgroups including control, I/R and HOE642+I/R. The LVDP, LVEDP, arrythmia coronary flow and the enzymatic activity in myocardium were measured in group A, and TUNEL method was applied to probe apoptosis in group B. RESLUTS: It was found that the LVEDP, arrythmias and the enzymatic activity including CK-MB and LDH were significantly lower in group HOE-Pr+I/R than that in group I/R, while the LVDP was obviously higher in HOE-Pr+I/R than that in I/R. The administration of HOE642 during ischemia could decrease LVEDP, arrythmias and enzymatic activity in myocardium, but not the LVDP. Furthermore, the results showed that HOE642 could inhibit apoptosis induced by ischemic/reperfusion injury. CONCLUSIONS: HOE642 is an effective cardio-protector in case of ischemic/reperfusion injury especially when it is applied before ischemia. The inhibition of apoptosis might be involved in the mechanisms underlying the protective effect of HOE642.

This article was aimed to study the optimum technological conditions of roller compaction of FKⅣ gran-ules. This experimentation compared content of two granule preparation techniques which were the dry process gran-ulation and the wet process granulation, and adopted L9(34) orthogonal experiment to study the technological parame-ters of FKⅣ granules. The dry process granulation was selected. And factors such as roller pressure, roller speedand moisture content of power, which influence the result of granule yield were also studied in the dry process gran-ulation. The results showed that the optimum technological conditions were roller pressure at 5.0 Mpa, roller speed at 400 rpm, and moisture content of power at 3.0%. It was concluded that the roller compaction process of FKⅣ gran-ules was feasible in production which was able to meet the requirement of production.

Objective To analyze clinical characteristics of pemphigoid nodularis. Methods Seven cases of pemphigoid nodularis were included in this retrospective study. The clinicopathological features of pemphigoid nodularis were retrospectively analyzed, including patients′gender, age at onset, clinical manifestations, treatment and follow?up. Results Of the 7 patients, 4 were female and 3 were male, with the median age at onset being 59 years. Clinical manifestations mainly included markedly pruritic prurigo?like lesions and nodular lesions with or without blisters. The most common misdiagnoses were nodular prurigo and eczema. Pathology showed epidermal hyperplasia and subepidermal clefts, collagen hyperplasia in the papillary dermis, and perivascular infiltration of lymphocytes and eosinophils in the superficial dermis in all the patients. Direct immunofluorescence assay showed linear deposition of IgG and C3 in the basement membrane zone, and indirect immunofluorescence was positive in 2 patients. Glucocorticoids combined with immunosuppressants were effective in all the patients. Conclusions Pemphigoid nodularis is easy to be misdiagnosed, and immunopathology is helpful for its diagnosis. Glucocorticoids combined with immunosuppressants appear to be effective for its treatment.

Objective To investigate the age distribution and types of human papillomavirus (HPV) cervical infection in patients in Wuhan region, so as to provide scientific basis for the prevention and treatment of HPV infection and cervical cancer.Methods 9 915 exfoliated cervical cell specimens from patients in Wuhan Medical and Health Center for Women and Children between January 2015 and March 2016 were performed HPV genotyping (21 subtypes), clinical data of 1 732 HPV positive cases were statistically analyzed.Results HPV-positive rates in ≤25, 26~, 36~, 46~, and ≥56 age groups were 22.15%, 15.90%, 17.04%, 19.97%, and 17.57%,respectively (χ2=36.587,P<0.01),HPV-positive rates in ≤25 and 46~ age groups were both higher than other age groups.There were significant differences in single infection and multiple infection rates among different age groups respectively(χ2=14.39, 36.51,respectively, both P<0.05),single infection rate was highest in 46~ and ≤25 age groups (15.41% and 15.24% respectively);multiple infection rates was highest in ≤25 and ≥56 age groups (6.90% and 5.86% respectively).The percentage of single infection and multiple infection were 75.58% and 24.42% respectively, the major single infection type was HPV high-risk subtype (84.34%),the major multiple infection types were high-risk and high-risk compound subtype as well as high-risk and low-risk compound subtype, accounting for 60.52% and 38.77% respectively.The main single infection types were HPV high-risk subtypes 33, 68, 31 and 16, as well as and low-risk subtype 11, the ratios of single infection to multiple infection were 3.13, 2.03, 1.71, 1.67 and 2.00 respectively.Conclusion Cervical infection rates in women in Wuhan region is high in ≤25 and 46~ age groups, there are differences in the distribution of different HPV subtypes of single infection and multiple infection.

Total aerobic plate counts for bacterial colonies in the Bullacta exarata ranged from 7. 3?10 5 to 2. 8?10 6 cells per gram. 217 strains of bacteria were isolated from the Bullacta exarata and 88. 5% of them were Gram-negative rod . The predominant genera were composed of Enterobacteriaceae (61 strains), Aeromonas (58), Vibrio (27), Pseudomonas (21). The results indicate that total bacteria numbers exceeds state standard by 1～2 quantity level in every samples. The coliform bacteria numbers exceeds health standard in sample of seven and nine month. It should be brought to attention. The microflora were composed of ten genus , predominant Bacillus of rearing shoal were few in the Bullacta exarata that may play a special role for regulating and controlling the microbial community .

Objective To investigate the potential clinical factors associated with the prognosis and relapse of adult onset Still's disease(AOSD).Methods The factors possibly influencing the prognosis and relapse of AOSD were analyzed by logistic regression and COX regression in the cohort study.Ninety-six con- secutive inpatients of AOSD diagnosed based on Yamaguchi criteria in the hospital from March 1996 to September 2004 were included in the study.Results Nine cases(9.4%)were lost during the follow-up. Eleven patients(12.6%)were diagnosed as other diseases(5 with other rheumatic diseases,4 with tumor and 2 with infections)in the 87 follow-up cases.In 76 cases,3 patients(3.9%)died and 33 patients(43.4%) got remission over one year after treatment.Splenomegaly(OR=3.14,95%CI=1.01～9.74)and treated with methotrexate(OR=0.22,95%CI=0.07～0.67)were associated with the prognosis from the logistic regression analysis of the 76 cases.The serum ferritin(RR=I.05,95%CI=1.01～1.08)and treated with methotrexate (RR=0.13,95%CI=0.02～0.76)were associated with relapse from the COX regression analysis of the 61 remis- sion cases.Conclusion We need to be very cautious in the follow-up of AOSD patients because some of them may change to other diseases.Methotrexate may be an importent therapy of AOSD not only in improve- ment the prognosis but also in reduction of relapse.

AIMTo investigate the vasodilating effect and its mechanism of ethanol on isolated rat thoracic aorta at different resting tension.

METHODSThe tension of the isolated Sprague-Dawley rat thoracic aorta rings perfused with different concentrations of ethanol was measured using organ bath technique.

RESULTSAt different resting tension (1.0, 1.5, 2.0, 2.5, 3.0, 3.5 and 4.0 g), ethanol (0.1-7.0 per thousand) caused a concentration-dependent relaxation on endothelium-denuded aortic rings precontracted with KCl (6 x 10(-2)mol/L) or phenylephrine (PE, 10(-6) mol/L), and the vasodilating effect was the most potent when the aortic rings were at the resting tension of 3 g. Ethanol had much less vasodilating effect on endothelium-intact aortic rings. Ethanol at 3 per thousand (the maximum-effect concentration) inhibited the CaCl2 induced contraction and downward shifted concentration-response curve of endothelium-denuded aortic rings pre-contracted with KCI or PE at the resting tension of 3 g. Incubation of aorta with ruthenium red (10(-5) mol/L) or heparin (50 mg/L) decreased the vasodilating effect of ethanol (3.0 per thousand) on endothelium-denuded aorta precontracted with PE at the resting tension of 3 g.

CONCLUSIONEthanol induces endothelium-independent relaxation on rat thoracic aorta, which is concerned with the resting tension. This effect of ethanol may be mediated by the inhibition of voltage-dependent and receptor-operated Ca2+ channels in the vascular smooth muscle cells. The inhibition of the ryanodine receptor and trisphosphate inositol (IP3) pathway may also contribute to this effect.

Chinese medicine pair (CMP) was frequently applied in traditional Chinese medicine (TCM) clinic, and its significance was shown in long-term clinical practices and many accumulated experiences. It is the unique combination of two relatively fixed Chinese medicines in TCM clinic with the basic feature and principle of TCM compatibility, is the most fundamental and the simplest form of TCM formulae with certain theory basis and combinatory reason, which is proven effective. And the unique combination is frequently used for achieving mutual reinforcement or detoxication. CMP is an intermediate point between single herb and many TCM formulae, reflecting the regularity of TCM formulae compatibility and connotation of differential treatment. This paper analyzed and summarized the basic characteristics, development process and research significance of CMP, which aims to lead the modern basic and applied research on compatibility theory of CMP.
