To investigate the curative effect of minimally invasive sclera buckling on single retinal detachment.METHODS:Totally, 100 cases of patients with retinal detachment ( 106 eyes ) enrolled in our hospital were randomly divided into observation group and control group, 53 eyes in each group. Patients in observation group were treated with minimally invasive sclera buckling, while patients in control group received traditional limbal conjunctival incision. After surgery, patients were all followed up for 6 ~18mo, during which the retinal recurrence situation, degree of vision enhancement and compliance occurrence rate was recorded. RESULTS: The retinal reattachment rate once of observation group (96. 22%) was significantly higher than that of control group (88. 68%), there was statistically significance (P<0. 05). The vision enhancement rate of observation group (84. 90%) was significantly higher than that of control group (71. 70%), there was statistically significance (P<0. 05). The compliance occurrence rate of observation group (11. 32%) was significantly lower than that of control group (32. 08%), there was statistically significance (P<0. 05).CONCLUSlON: The improved minimally invasive sclera buckling can significantly enhance the curative effect for retinal detachment, decrease the compliance occurrence rate, improve vision function, and is a scientific, practical and rigorous tool for retinal detachment treatment.

Influenza virus hemagglutinin (HA) is a key factor in the virus's invasion of host cells, involving the binding of the virus to target cells and the fusion of membranes. The proteolytic cleavage and activation of HA by host proteases are prerequisites for the virus to recognize host cells and initiate membrane fusion, and are also essential for viral infection of the host. This article summarizes the proteolytic activation of different subtypes of influenza virus HA by type II transmembrane serine proteases, human tissue kallikreins, and other host proteases, and discusses their potential as targets for antiviral therapy.

The challenge of the emergence of drug-resistant influenza strains, which is caused by wide spread utilization of direct-acting antivirals (DAAs), accelerates the research and exploration towards host targeted agents. In contrast to DAAs targeting viral replication components, host targeted agents, which regulate host factors and pathways linked to viral replication, can interfere the replication of influenza. Additionally, the innate immune system is activated by influenza during the early stage of infection, so manipulating the innate immune response may prevent the viral infection. However, the excessive inflammatory response induced at the late phase of influenza infection would lead to severe tissue injures. Thus, it is very important to explore drugs with anti-inflammatory actions to suppress these immune imbalances and tissue injures. Here we overview the current progresses about host targets related to anti-influenza drugs.

Objective To understand human rhinovirus (HRV) etiology of acute lower respiratory tract infection (ALRTI) in children in Shanghai area and establish a nested reverse transcription- polymerase chain reaction (nested RT-PCR) assay.Methods Three hundred and forty-two naso- pharyngeal secretion (NPS) samples from ALRTI cases who were hospitalized were collected during January 2005—December 2005.Nested RT-PCR techniques were used to detect HRV-specific RNA.The PCR products were sequenced and data of nucleotides were analyzed.The proportion of HRV infection in children with ALRTI,the distribution of gender,age and season,and clinical char- acteristics were also investigated.Results Forty-six (13.5%) of 342 samples were HRV positive detected by nested RT-PCR.The sequences of 15 positive samples shared high homology of 83%- 97% with HRV sequence in GenBank.Within the 15 positive samples,nucleotide homology varied from 64.4% to 98.4%,and the ratio of genetic variation was from 1.6% to 48.3%./00.These 15 ampli- cons attribute to the two branches of HRV cladogram.The sequences of 15 amplieons were highly varied,in which single nucleotide mutation and several nearby nueleotides mutations were found. Ribonucleotide deletion and insertion in the nucleotide sequence was also found.HRV positive sam- ples were detected in 33 boys and 13 girls,respectively.The ratio of infection cases between boys and girls was 2.5:1.Of 46 HRV infected cases,27 (58.7%) were less than 12 months of age and 38 (82.6%) were less than 3 years old.HRV infected ALRTI occured all the year round and peaked from March to May.Of the patients whose NPS samples were HRV positive detected by nested RT-PCR,45 patients were diagnosed with bronchopneumonia and 1 was diagnosed with asthmatic bronchitis.Fever of most patients was moderate.The peripheral blood leukocyte counts in thirty-nine (84.8%) patients were less than 10?10~9/L.Neutrophil percentages in thirty-seven (80.4%) patients were less than 0.50.C-reactive protein of thirty-six (78.3%) patients were less than 8 mg/L. All of these features were the characteristics of viral pneumonia.The complications were not common and conditions of most patients were not severe.All the children were cured.Conclusions This nes- ted RT-PCR technique is highly specific,rapid and convenient for the detection of HRV RNA in NPS of patients with ALRTI and the genome of HRV viruses is highly variable.The incidence of HRV infection predominates in children in Shanghai area.ALRTI of HRV is short of specificity and condi- tions of most patients are not severe and their prognoses are fine.

Objective To investigate the clinical characteristics, diagnosis and treatment of placenta increta.Methods A retrospective analysis was carried out on 13 admitted cases of placenta increta from 1989～2006. Results Among the 13 cases analysed, 5 cases with a history of Caesarian section had a 0% success rate of treatment with conservative care (0/5), 100% less than that of cases with no history of Caesarian section (8/8), P＜0.05; the success rate of treatment of partial placenta increta with methotrexate with Jia Wei Sheng Hua Tang was 100%. Conclusion Caesarian section is a risk factor of placenta increta, and its prognosis is poor; however, Jia Wei Sheng Hua Tang has proven satisfactory as a supplementary treatment for placenta inereta.

OBJECTIVE To intensify the management of the acupuncture department and prevent and control nosocomial infection.METHODS During the course of the management of the acupuncture department,the causes of nosocomial infection were found through analyzing the possible reasons of nosocomial infection and a series of relevant measures were taken to improve the control of nosocomial infection.RESULTS In order to control nosocomial infection in acupuncture department we needed to strength the disinfection management in the following aspects:air in the room,medical procedures and implement,medical staff hands and medical disposals.CONCLUSIONS Strict management is the important measures to reduce the nosocomial infection.

Objective To study the impact of postoperative aerobic exercise on the cardiac function of breast cancer patients during anthracyclines-based chemotherapy. Methods Sixty cases of female breast cancer pa-tients, from June 2014 to December 2015 for anthracyclines-based chemotherapy, were randomly divided into ex-perimental group (n = 30) and control group (n = 30). Four cycles of conventional anthracyclines-based chemotherapy were conducted in control group, while three times of aerobic exercise per week were added in exper-imental group until the end of treatment course apart from conventional treatment. The peak oxygen consumption (VO2max) and maximum heart rate (HRmax) were measured before and after chemotherapy in both groups, ac-companied by ECG monitoring and blood collecting to measure the changes in their N-terminal pro-brain natriuretic peptide (NT-proBNP), serum creatinine (SCr) and kinase isoenzyme (CK-MB). Results No significant differ-ences in various indicators before chemotherapy were reported between two groups (P>0.05). After chemotherapy, VO2 max/kg [(21.9 ± 3.6) vs. (14.5 ± 2.8) mL/(min·kg)], VO2 max [(1 523 ± 186) vs. (911 ± 185) mL/min] and HRmax[(115 ± 15) vs. (129 ± 16) beats/min] in experimental group were significantly improved when com-pared with those in control group; significant differences in hematological levels and ECG changes were also ob-served between two groups. Conclusion Aerobic exercise during chemotherapy can mitigate the cardiotoxicity of anthracyclines to patients, which provides a new idea and therapy to reduce the incidence of clinical cardiovascular events induced by anthracyclines-based chemotherapy.
