Objective To investigate the influence of primary caesarean section on re -caesarean operation of advanced pregnant women.Methods 251 advanced pregnant women were chosen to research,and they were divid-ed into research group(traditional abdominal longitudinal incision)and control group (novel abdominal transverse incision)by primary caesarean section.The clinical indicators,abdominal adhesion and complication occurrence between the two groups were compared.Results Operation time[(57.98 ±12.26)min vs.(78.39 ±17.54)min], amount of bleeding during operation[(248.59 ±17.32)mL vs.(377.18 ±56.04)mL],anal exhaust time[(40.26 ± 7.25)h vs.(56.02 ±8.23)h]and length of stay[(7.21 ±2.06)d vs.(9.94 ±3.13)d]of the research group were all lower than the control group,the differences were statistically significant (t =10.576,24.018,16.129,8.069,all P <0.05).The severity of abdominal adhesion of the research group was lighter than the control group,and the differ-ence was statistically significant (U =2.601,P <0.05).No severe complications such as asphyxia occurred in the two groups.Postpartum hemorrhage and abdominal adhesion occurrence in the research group were lower than the control group ,there was significant difference in abdominal adhesion between the two groups (χ2 =1 8 .8 6 2 ,P <0.05).Conclusion Primary caesarean section has influence on clinical indicator,abdominal adhesion severity and complications in re -caesarean operation of advanced pregnant women,and novel abdominal transverse incision has greater influence,traditional abdominal longitudinal incision little.

Mantle cell lymphoma (MCL) is a group of highly aggressive non-Hodgkin lymphoma (NHL) in small B-cell lymphoma, accounting for 6 % of NHL incidence. MCL is characterized with its concealed onset, strong aggression, high malignancy and poor prognosis. Therefore, more attention should be paid to the diagnosis and differential diagnosis of MCL in clinic. Recently, diagnostic models of molecular pathology, researches on cyclin D1 protein negative MCL, staging prognosis and stratification treatment of MCL are worthy of attention.

Objective To explore the relationship between complications and prognosis of chronic severe hepatitis(CSH).Methods The clinical data of 520 patients with CSH treated in our hospital were retrospectively analyzed.Results The most common complications of CSH were ascites,electrolyte disturbance and spontaneous peritonitis,and their total occurring rate was over 50%.Among all the complications,cerebral edema and cerebral hernia had the worst prognosis,failure in treatment and mortality were 100%.Secondary were followed by hepato-renal syndrome,upper digestive tract hemorrhage and hepatic encephalopathy that resulting to effectless rate and mortality of 90% .The effectiveless rate and mortality rose along with increase in number of complications .Meanwhile,the severity of hepatic encephalopathy was closely related to mortality in the patients.Conclusions Effective treatment of complications of CSH and reduction of occurring rate of the complications are very important for decreasing mortality of patients with CSH.

Objective To study features and significance of clinical stages and types of severe acute respiratory syndrome (SARS). Methods The clinical features of 330 patients with SARS were analyzed by SPSS 11.0 and SDAS software packages, and the standard for classification of clinical stages and types of SARS were studied. Results The disease course of SARS could be divided into four stages, namely, incubation stage, initial stage, climax stage and convalescence stage. The period of incubation stage was 1~12 (5.70?2.45) days. The initial stage was the pathoformic phase during 1 st~10 th (3.98?2.48) days after the onset. The fever was the first symptom and there were usually no catarrhal symptoms. Meanwhile, no abnormality was found in the chest X-ray examination. The climax stage included 3 sequential phases of pulmonary inflammatory exudation, pulmonary tissue consolidation and ARDS or multi-organ failure. In the phase of pulmonary inflammatory exudation, there were serious cough, mild shortness of breath and hypoxemia. Furthermore, chest X-ray examination showed that there was exaggeration of lung markings, haziness or patchy opacity. In the phase of pulmonary tissue consolidation, type I respiratory failure was usually seen in the patients. Shortness of breath and hypoxemia became more serious. Chest X-ray examination showed that the area of consolidation continued to enlarge to include the entire lung. The convalescence stage usually appeared 3 weeks after the onset and lasted for 5～56 (24.37?8.81) days. This stage could further be divided into phase I (complete recovery) and phase II (possible existence of pulmonary fibrosis). SARS could be clinically classified into mild type (ordinary type), severe type and extremely severe type (fulminant type) with a mortality of zero, 5.76% and 61.54%, respectively. There were very great differences in clinical features in three types of SARS. Conclusions SARS could be divided into the incubation stage, initial stage, climax stage and convalescence stage. The climax stage included 3 phases, i.e. pulmonary inflammatory exudation, pulmonary tissue consolidation, and ARDS or MOF. The convalescence stage could be divided into phase I (complete recovery) and phase II (possible existence of pulmonary fibrosis). SARS could be classified as mild type, severe type and extremely severe type.

Objective To analyze the clinical features of severe acute respiratory syndrome(SARS) in order to look for premonitory signs of deterioration of patients suffering from SARS. Methods Three hundred and thirty patients with SARS referred to the Chinese Disease Center(CDC) in Beijing were studied retrospectively by SPASS and SDAS software. The data reviewed included clinical manifestations, laboratory findings, and X-ray pictures. Results The prognosis of mild SARS was good with a cure ratio of 100%. Chest radiography revealed opacity or small subtle opacity in lung periphery in 53.1%, there were no signs of acute lung injury in 67.2%, and the opacity disappeared rapidly. In patients with severe SARS, the disease course was longer(41.3?5.6day), the duration of high fever was longer (8.66?3.22day), with the highest temperature reaching 39.04?0.71℃. The duration of respiratory insufficiency was also longer(8.80?4.56day), and 71.8% of them manifested acute lung injury, involving a large area of the lung, with central lesions in 21.8% or mixed in 50%. The opacity was denser, and it took a longer period to resolve. The levels of LDH, HBDH, ESR and CK-MB were high, with HBDH/LDH ratio ranged from 0.8 to 1.0. The mortality was high(14.54%). Logistic regression analysis showed that the premonitory mode of deterioration of the disease was P y=1=? s /(1+? s)(S=-10.598+0.102A+0.592B+0.077C+0.494D), with sensitivity of 86.67%, and specificity 80%, and it was correlated with age, duration of respiratory insufficiency, ESR, and duration of high temperature. Conclusions The premonitory mode of deterioration of SARS is a new, simple, low-cost, biomathematically and pathophysiogically based index. It allows the prediction of deterioration and severity of SARS.
