Objective To investigate the clinical features and effective treatment of patients with severe type A H1N1 flu in Wenzhou. Methods The clinical data of 42 hospitalized patients with severe type A H1N1 flu were analyzed and the clinical features were summarized. Results A total of 42 patients with severe type A H1N1 flu all began with fever and cough. The symptoms of expectoration, pharyngalgia, chilly accounted for 92. 9%, 90. 5% and 42. 9%, respectively. The peripheral leucocyte counts were normal or reduced. C-reactive protein and erythrocyte sedimentation rate levels both increased in 30 patients (71.4%). About 95.2% (40/42) patients had changes of pulmonary imaging. All of the patients were treated with oseltamivir and effective antibiotic drugs as well as symptomatic management. No patients was treated with glucocorticoid. The patients with underlying diseases were given proper treatment. Three cases were treated with antifungal therapy and 3 pregnant patients were timely terminated of pregnancy. Conclusions Severe type A H1N1 flu progresses rapidly and the lower respiratory tract is involved soon after onset. Therefore, the patient should be diagnosed early and treated promptly after presenting fever, which will lead to good prognosis.

Objective To investigate the isolation rate, distribution and trend of nontuberculous mycobacteria (NTM) in Wenzhou during 2014 to 2016.Methods Sputum or alveolar lavage specimens of patients with suspected pulmonary tuberculosis were collected for mycobacteria culture from January 2014 to December 2016.Mycobacterium culture positive strains were further identified by gene chip, 16S rRNA and hsp65 gene sequencing.SPSS 19.0 software was used to analyze the data.Results After excluding repetitive strains, 3 295 mycobacteria strains (MTB) were isolated from respiratory specimens, included 3 032 mycobacterium tuberculosis complex strains, 238 NTM strains, 20 Gordon genera strains, 3 Nocardia genera strains and 2 Tsukamurella genera strains.The proportion of NTM among confirmed mycobacteria was 8.5％ (86/1 006), 6.7％ (72/1 079) and 6.8％ (80/1 185) in 2014, 2015 and 2016, respectively (x2 =2.459,P ＞ 0.05).The overall prevalence of NTM was 7.3 ％ (238/3 270).There were 15 species of NTM, and the most common NTM strain was Mycobacterium intracellulare (52.5％,125/238), followed by Mycobacterium abscessus (22.7％, 54/238) and Mycobacterium avium (10.1％, 24/238), other species were only accounted for 14.7％ (35/238).The ranking of Mycobacterium avium went up rapidly from the fifth in 2014 to the second in 2016 (x2 =18.259, P ＜ 0.01), while proportion of Mycobacterium abscess, dropped from 34.9％ (30/86) in 2014 to 17.5％ (14/80) in 2016 (x2 =7.335, P＜0.01).Among patients from whom the NTM strains were isolated, 56.7％ (135/238) were male and most of them were aged 45 years or above (79.8％, 190/238).Conclusions In the past three years, the trend of NTM isolation rate in Wenzhou is steady.The most prevalent NTM species is Mycobacterium intracellulare, followed by Mycobacterium abscessus and Mycobacterium avium.Mycobacterium avium shows a continuously upward trend, while the separation of Mycobacterium abscessus shows a downward trend.

OBJECTIVE To observe the effect of natrin from Naja naja atra(Chinese cobra)on intracellular free calcium overload,and to discuss the protective effect and the possible mechanism of natrin on myocardium calcium(Ca2+)and potassium(K+)ion channels in the primary cardiomyocytes of SD neonatal rats. METHODS The primary cardiomyocytes of SD neonatal rats were used,which were respectively pretreated with natrin 5,25 and 125 mg · L-1 for 24 h before injury was induced by H2O2 0.3 mmol · L- 1. The dynamic variation of intracellular calcium was monitored by laser confocal microscopy using Fluo-3 as Ca2+fluorescence probe. Additionally,the cardio myocytes of neonatal rats were pretreated for 24 h using different concentrations of natrin 5,25,125 mg · L-1 and verapamil 5 nmol · L-1,followed by exposure to H2O2 0.3 mmol · L-1 for 15 min. Then,the mRNA expressions of calcium channels subunits Cav1.2,Calm,RyR2 and potassium channel Kir6.2 were analyzed by FQ-PCR method. RESULTS Laser confocal microscopy revealed that H2O2 obviously caused calcium overload in cardiomyocytes, giving rise to 49.37% fluorescence increase in intracellular calcium compared with the control group(P<0.01). However,natrin 5,25 and 125 mg·L-1 resulted in 27.52%, 12.71% and 5.15% fluorescence increase in intracellular calcium,respectively,compared with the control group(P<0.01). Moreover, the PCR results showed that the mRNA expressions of Cav1.2, Calm and RyR2 in the myocardial cells treated with H2O2 were increased 2.78,2.26,and 5.34 times as compared with the control group,while Kir6.2 displayed a 1.79-fold expression level(P<0.01). By contrast, the combination of natrin and verapamil significantly decreased the mRNA expression of Cav1.2,Calm and RyR2,compared to the H2O2-treated group(P<0.01). Meanwhile,the expression of Kir6.2 was considerably higher than that of the H2O2-treated group(P<0.05). CONCLUSION Natrin can reduce the intracellular calcium overload of cardiomyocytes induced by H2O2 and shows a protective effect against oxidative damage for cardiomyocytes. The possible mechanism is that natrin can decrease the mRNA expression of Cav1.2,Calm,RyR2 and increase the expression of Kir6.2 of the H2O2-induced cardiomyocytes.

Objective: To investigate the analgesic mechanism of Tuina (Chinese therapeutic massage) by observing the effect of the N-methyl-D-aspartate receptor subunit 2B (NR2B)/postsynaptic density-95 (PSD-95) pathway on the dendritic structure of spinal cord dorsal horn in rats with lumbar disc herniation. Methods: Fifty Sprague-Dawley rats were randomly divided into a blank group, a model group, a Tuina group, a blocker agent group, and a blocker agent + Tuina group. The sciatic nerve chronic constriction injury (CCI) model was prepared by the sciatic nerve ligation method. From the 4th day after modeling, rats in the Tuina group and the blocker agent + Tuina group were subject to daily Tuina intervention, and those in the blocker agent group and the blocker agent + Tuina group were daily intrathecally injected with NR2B blocker agent (MK-801). The spontaneous pain score was used to observe the pain behavior of all rats. The expression levels of NR2B and downstream PSD-95 were measured by immunohistochemistry, and the dendritic structure changes were observed by Golgi staining for rat spinal cord dorsal horn after 14 d of continuous intervention. Results: Compared with the blank group, the degree of rat spontaneous pain after CCI was elevated in both the model and the Tuina groups (P<0.01) and was reduced in the Tuina group after the Tuina intervention compared with the model group (P<0.05). Compared with the model group, the rat spontaneous pain level after blocking NR2B was reduced in both the blocker agent group and the blocker agent + Tuina group (P<0.05). The NR2B and PSD-95 protein levels were significantly higher in the model group compared with the blank group (P<0.01); the total number of dendritic branches was increased (P<0.01), and the total dendritic length became longer (P<0.01) in the spinal cord dorsal horn. The rat NR2B and PSD-95 protein levels were significantly decreased in the Tuina group compared with the model group (P<0.01); the total dendritic branch number was reduced (P<0.01) and the total length was shortened (P<0.01) in the spinal cord dorsal horn. After blocking NR2B, the expression levels of NR2B and downstream PSD-95 protein were significantly lower in both the blocker agent group and the blocker agent + Tuina group compared to the model group (P<0.01). The total branch number was significantly reduced (P<0.01), and the total length was significantly shortened (P<0.01) of the dendrites in the spinal cord dorsal horn. Conclusion: Tuina may exert an analgesic effect by remodeling the dendritic structure in the spinal cord dorsal horn in rats with lumbar disc herniation, and its mechanism may be related to the inhibition of NR2B/PSD-95 signaling pathway.

Objective To investigate the possible risk factors for the progression of abdominal aortic calcification (AAC) in MHD patients.Methods Total of 170 patients on MHD between June 2014 and October 2014 in the dialysis center of the Second Hospital of Tianjin Medical University were included prospectively.Lateral lumbar radiography were applied to evaluate patients' AAC score (AACs) at baseline and after two-years of follow-up respectively.According to the change of AACs,the patients were divided into rapid AAC progression group and non-rapid AAC progression group.Multivariable Logistic regression models were used to determine the risk factors for the progression of AAC in MHD patients.Results At baseline,the presence of AAC (AACs≥1) was 43.5％(74/170).The mean follow-up duration was 27.6(24.7,28.0) months.AACs were available in 111 patients,and the presence of AAC was 78.4％(87/111).During the follow up,36 patients developed new AAC;rapid AAC progression was seen in 54 patients,and non-rapid AAC progression was seen in 57 patients.Multivariate Logistic regression analysis demonstrated that hyperphosphatemia (OR=4.373,95％ CI 1.562-7.246,P=0.005) and high density lipoprotein (HDL) (OR=0.031,95％CI 0.003-0.338,P=0.004) were independent risk factors for AAC progression in MHD patients.Conclusions Hyperphosphatemia and low HDL may promote the progression of AAC.Well-controlled serum phosphate and lipid metabolism may slow the progression of vascular calcification,reducing cardiovascular morbidity and mortality.

Objective To study the prevalence and related risk factors of type 2 diabetes with coronary heart disease(CHD) and cerebral infarction after long-term treatment.Methods Two hundred and eighty-five patients with type 2 diabetes who had a hospitalization interval for four to twelve years between the first and second hospital stays were included in group A.Among them,85 patients (about 4 to 7 years) with a hospitalization interval about 5 years (4 to 7 years) between the first and second hospital stays(group B).100 patients with a hospitalization interval about 10 years (8 to 12 years) between the first and second hospital stays(group C).Blood pressure,blood glucose,HbA1c,blood lipids,myocardial enzymology,electrocardiogram,coronary angiography,cranial CT or MRI were tecorded.The prevalence of CHD and cerebral infarction were compare,regression analysis was conducted between coronary heart disease,cerebral infarction and the risk factors.Results DBP,FBG,PBG2h,TC,LDL-C of the second hospitalization were significantly lower than those of the first hospitalization.The morbidity of CHD and cerebral infarction increased along with the extension of the course.The morbidity of cerebral infarction in CHD patients were significantly higher than those in non-CHD patients with the interval about 10 years.Logistic regression analysis proved that age was risk factor and HDL-C was protective factor of CHD,SBP,FBG were risk factors of cerebral infarction.Conclusion The morbidity of CHD and cerebral infarction increased along with the extension of the course and there were significantly relationship between CHD and cerebral infarction in T2DM patients after about 10 years treatment.
