This study examined the change of reported incidence rate for viral hepatitis in Hubei province, China, between 2004 to 2010 to provide scientific evidence for viral hepatitis control. Reported viral hepatitis infection cases were queried from Centre for Disease Control of Hubei Province, China. The incidence of viral hepatitis A decreased steadily across the study period. Viral hepatitis B composed 85% of the viral hepatitis cases. When reported incidence rates for chronic hepatitis B increased, the rates of acute and unclassified cases dropped from 2005 to 2010. The reported viral hepatitis B incidence rate for males was around 1.5-2 times higher than for females. The average annual percentage change of reported viral hepatitis B incidence rates was 4%. The same index for viral hepatitis C was 28%. The reported viral hepatitis B incidence rate of people under 20 years old declined over the period. This decrease was mainly attributed to the recent implementation of vaccination plan. Reported incidence rate of viral hepatitis E also rose in those years. Having a better understanding on reported incidence rates of the present surveillance system is important for developing strategies for further prevention of viral hepatitis. In addition, the data showed that a surveillance system that differentiates new and former infected cases will be more effective in providing evidence for disease control.

Objective To investigate the clinical features of Crohn's disease(CD)and ulcerative colitis(UC)according to the Montreal classification.nethods The clinical data of 110 cases of CD or UC were reviewed.The age at diagnosis.location and clinical behavior were assessed with the Montreal criteria.Results CD patients diagnosed at an age younger than 16 years were rare(3.6%),the majority of the CD patients was diagnosed at 17-40 years old(65.5%).Although ileocolon lesions were most common in the patients diagnosed at 17-40 years old(37.3%),yet ileum lesions were a little more than those of other parts of digestive tract in the patients diagnosed after 40 years old(14.5%),the difference was not significant(P=0.054).Stricture frequently occurred(50.4%),especially when the lesions were located at ileum or ileocolon.Perforation rarely happened(5.3%).There was no significant difference between different location groups for clinical behaviors(P=0.096).The incidence of stricture or perforation was almost same among different age groups(P=0.984).UC patients mostly presented with mild or moderate symptoms even in the group with extensive lesion.UC patients with severe symptoms were rare(6.8%).There was no significant difference in severity between the groups with different extent of lesion (P=0.056).Conclusions The majority of CD patients was diagnosed at 17-40 years old.Stricture is much more than perforation,penetrating,occurring mostly at ileum.UC patients mostly present mild or moderate symptoms,no matter how extensive the lesion is.The extent of the lesion detected with coloscopic examination is not correlated to the severity of clinical manifestations.

ObjectiveTo investigate the effect of N-acetylcysteine on lung injury induced by cardiopulmonary bypass(CPB) in dogs.MethodsThirty-six healthy adult mongrel dogs of both sexes weighing 15-16 kg were randomly assigned into 2 groups (n =18 each):CPB group (group C) and N-acetylcysteine group(group N).Lung injury was produced by CPB.In group N N-acetylcysteine 150 mg/kg was injected iv immediately before CPB,followed by infusion at 20 mg· kg-1 · h-1 until 60 min after termination of CPB.Blood samples were taken from femoral artery before CPB (T0,baseline),30 and 60 min after termination of CPB (T1,T2 ).Oxygenation index ( OI =PaO2 ÷ FiO2 ) and respiratory index (RI =PA-(a) DO2 ÷ PaO2 ) were calculated.Six animals were sacrificed at each time point.Lung specimens were obtained for microscopic examination,and determination of transforming growth factor-β1 (TGF-β1) mRNA expression,MDA content and SOD activity.ResultsCPB significantly increased RI,MDA content and TGF-β1 mRNA expression and decreased OI and SOD activity at T1 and T2 as compared with the baseline values at T0 in group C.N-acetylcysteine administered before and during CPB significantly attenuated CPB-induced above changes in OI,RI,MDA content,SOD activity and TGF-β1 mRNA expression.Microscopic examination showed that N-acetylcysteine significantly ameriorated CPB-induced lung damage.ConclusionsN-acetylcysteine administered before and during CPB can attenuate CPB-induced lung injury by inhibiting lipid peroxidation response and down-regulating TGF-β1 expression.

A N-acetylneuraminate lyase gene (shnal) from Staphylococcus hominis was cloned into pET-28a and expressed in Escherichia coli BL21 (DE3) host cells. The recombinant enzyme was purified and characterized. It is a homotetrameric enzyme with the optimum pH at 8.0 for the cleavage direction and the optimum pH and temperature were 7.5 and 45 degrees C for the synthetic direction. The activity of ShNAL is stable when incubated at 45 degrees C for 2 h but decreased rapidly over 50 degrees C. ShNAL showed high stability in a wide range pH from 5.0 to 10.0 with the residual activity being > 70% when the enzyme was incubated in different buffers at 4 degrees C for 24 h. Its K(m) towards N-acetylneuraminic acid, pyruvate and ManNAc were (4.0 +/- 0.2) mmol/L, (35.1 +/- 3.2) mmol/L and (131.7 +/- 12.1) mmol/L, respectively. The k(cat)/K(m) value of Neu5Ac, ManNAc, and Pyr for ShNAL were 1.9 L/(mmol x s), 0.08 L/(mmol x s) and 0.08 L/(mmol x s), respectively.

The aim of this research was to estimate the bioactivity of nano-hydroxyapatite/poly (L-lactic acid) composites in simulated body fluid. In vitro test showed that the pH value of simulated body fluid (SBF) declined gradually and the existence of hydroxyapatite (HA) particles neutralized the acid degradation product of poly (L-lactic acid) (PLLA). Bone-like apatite deposited on the surface, and silkworm-like crystals and plate-like clusters appeared after soaking. At the same time, there were many honeycomb-like pores caused by nano-composite degraded. The results indicated that the hydroxyapatite/poly (L-lactic acid) nano-composites have good bioactivity and degradation characteristics.

Objective:To evaluate the effect of combined teaching of optical laryngoscope and general laryngoscope on anesthesia undergraduate practice.Methods:A total of 40 anesthesia undergraduate students were randomly divided into group A (using the optical laryngocope only in the first month and the general laryngoscope only in the second month, n=20), and group B (using the general laryngocope only in the first month and the optical laryngoscope only in the second month, n=20). The teaching effect was evaluated through the first month and the second month of tracheal intubation assessment and questionnaire survey results. SPSS 23.0 was used for t test and chi-square test. Results:In the first month, the success rate was 90% in group A and 60% in group B, which showed that the success rate of group B was lower, with significant differences ( P < 0.05). The time for tracheal intubation in group A was (61.8±5.0) s, and that in the group B was (83.0±4.9) s, showing that the time of group B was longer, with significant differences ( P < 0.05). The complications in group A was 5%, and that in group B was 14%, showing that the group B had more cases of implications, with significant differences ( P < 0.05). In the second month, there was no significant difference in the one-time success rate, the time for tracheal intubation, and complications between the two groups ( P > 0.05). There was no significant difference in one-time success rate and complications between groups. Both groups showed that the time for general laryngoscope intubation was longer, with significant differences ( P < 0.05). All of the students believed that applying optical laryngoscope teaching was beneficial and could enhance the interest of learning, and the combination of the two methods was better. Conclusion:Using the optical laryngoscope first and then the general laryngoscope teaching is more beneficial for students to master the two methods of tracheal intubation, improve the success rate, reduce complications, and cultivates their self-confidence.

Objective To summary the hospitalization costs of lung cancer patients, and analyze the influence factors in these patients, and provide basis for controlling hospitalization costs of lung cancer patients. Methods The hospitalization costs data of hospitalized lung cancer cases in Wuhan from 2018 to 2020 were collected from medical records. Nonparametric test was used to analysis the data for single factor analysis. The patients were divided into two groups according on the upper quartile value of hospitalization cost, that is high-cost group (the cost ≥ the upper quartile value) and normal cost group (the cost “four major hospitals in Hubei^” respectively. The hospital type is an independent influencing factors, compared with specialized hospital, the OR is 4.726 for general hospital. The hospitalization days is the independent influencing factors, more hospitalization days has high cost. The treatment mode is the independent influencing factors, compared with non-operative treatment, the OR is 556.129, 18.156 and 5.212 for surgical model, radio therapy model and interventional model respectively. Conclusion The age, hospital level, hospital type, hospitalization days and treatment mode are the independent influencing factors of hospitalization costs. To reduce the hospitalization cost of lung cancer patients, we should standardize the diagnosis of lung cancer patients, and focus on standardizing the treatment mode, also considering other influencing factors, such as hospital level, hospital type.
