ObjectiveTo study the effects of placental transfusion of umbilical cord milking on very low birth weight (VLBW) infants. Methods Fifty-seven VLBW infants born from September 2011 to May 2014 who had umbilical cord milking at birth were selected as experimental group. Sixty-one VLBW infants born from January 2008 to August 2011 who had normal cord clamping at birth were selected as control group. The complications of VLBW infants, blood transfusion, frequency of using pulmonary surfactant (PS), the duration of mechanical ventilation, the duration of oxygen and mortality were compared between two groups.Results The incidence of severe asphyxia, IVH and anemia was signiifcantly lower in experimental group than in control group (P< 0.05). The blood transfusion and transfusion volume, duration of mechanical ventilation, and duration of oxy-gen were signiifcantly lower in experimental group than in control group (P< 0.05).Conclusions Umbilical cord milking can reduce the incidence of severe asphyxia, IVH and anemia. It also can reduce the blood transfusion, the duration of mechanical ventilation, and the duration of oxygen in VLBW infants.

Objective     To share the clinical experience of video-assisted thoracoscopic surgery (VATS) anatomic basal segmentectomy by single-direction method. Methods     The clinical data of 352 patients who underwent VATS anatomic basal segmentectomy in West China Hospital between April 2015 and April 2021 were retrospectively reviewed, including 96 males and 256 females with a median age of 50 (range, 26-81) years. All basal segmentectomies were performed under thoracoscopy, through the interlobar fissure or inferior pulmonary ligament approach, and following the strategy of single-direction and the method of "stem-branch". Results    All patients underwent basal segmentectomy successfully (49 patients of uniportal procedure, 3 patients of biportal procedure and 300 patients of triportal procedure) without addition of incisions or conversion to thoracotomy and lobectomy. The median operation time was 118 (range, 45-340) min, median intraoperative blood loss was 20 (range, 5-500) mL, median drainage time was 2 (range, 1-22) d and median postoperative hospital stay was 4 (range, 2-24) d. The postoperative complications included pneumonia in 6 patients, prolonged drainage (air leakage duration>5 d or drainage duration>7 d) in 18 patients, cerebral infarction in 1 patient and other complications in 2 patients. All patients were treated well and discharged without main complaints. No perioperative death happened. Conclusion    VATS anatomic basal segmentectomy is feasible and safe. It can be performed in a simple manner following the strategy of single-direction.

OBJECTIVETo explore the effect of compound qizhu granule (CQG) on cellular immunity of chronic hepatitis B (CHB) patients.

METHODSTotally 103 CHB patients treated with lamivudin (LAM) for 6 months, who had partial virological response (HBeAg positive) were randomly assigned to two groups, 50 in the treatment group and 53 in the control group. All patients took LAM 100 mg (once a day) plus ADV 10 mg (once a day). Patients in the treatment group additionally took CQG, one dose per day. After one-year treatment hepatitis B virus (HBV) DNA negative rates, HBeAg seroconversion, levels of HBV specific cytotoxic T lymphocyte (CTL), non-specific CTL and natural killing (NK) cells were compared between the two groups.

RESULTSAfter 1-year treatment, HBV DNA negative rate of the treatment group was 88: 0% in 44 cases, slightly higher than that of the control group (41 cases, 77.4%), but with no statistical difference (P >0.05). HBeAg seroconversion of the treatment group was 32.0% in 16 cases, higher than that of the control group (8 cases, 15.1%), with statistical difference (P <0.05). Levels of HBV specific CTL (0.79%±0. 07%), non-specific CTL (19.4%±1.8%) and NK cells (14. 1%± 1.5%) of the treatment group were higher than those of the control group (0.58% ± 0.08%, 17.5% ± 1.7%, and 11.1%±1.5%, respectively; allP <0.01).

CONCLUSIONTreating CHB patients with partial virological response by ADV plus CQG could improve specific and non-specific cellular immunity, thereby elevating HBeAg seroconversion rate.

Objective： The aim of this study was to investigate the best choice of the three treatment modalities of preserving laryngeal functions in T3 laryngeal carcinoma. Methods： There were 94 cases with T3 laryngeal carcinoma (Stage Ⅲ and Ⅳ ) who were treated by three kinds of modalities of preserving laryngeal functions： definitive radiotherapy, salvage surgery for the failures of definitive radiotherapy, partial laryngectomy. We compared their survival curve, recurrence rate of the primary and secondary site, and the complications. Results： The survival curve of the partial laryngectomy groups was better than that of the definitive radiotherapy group in supraglottic carcinoma (P=0.0248). In glottial carcinoma, the survival curve of partial laryngectomy group and salvage surgery group were insignificantly different, both of them were better than that of definitive radiotherapy group (P=0.0075). The complication rate of the salvage surgery group was significantly higher than that of partial laryngectomy group (60％ Vs 16.7％ ); We regarded the definitive radiotherapy group and salvage surgery group as one group, it's primary site recurrence rate was significant higher than that of partial laryngectomy group (45.8％ Vs 19.4％ ). Conclusion： Partial laryngectomy is the most effective way among the three modalities of preserving laryngeal functions to treat T3 laryngeal carcinoma.

Background Thymectomy is an established treatment for myasthenia gravis (MG),and video-assisted thoracoscopic surgery (VATS) thymectomy has become an acceptable surgical procedure.This study aimed to compare the results of VATS thymectomy and open thymectomy and to identify the prognostic factors after thymectomy.Methods The clinical data of 187 consecutive thymectomies performed between July 2000 and December 2009 were retrospectively reviewed; 75 open thymectomies and 112 VATS thymectomies.Clinical efficacy and variables influencing outcome were assessed by Kaplan-Meier survival curves and Cox proportional hazards regression analysis.Results The operative blood loss in the VATS group was significantly less than that in the open group ((62.14±55.43)ml vs.(137.87±165.25) ml,P ＜0.05).The postoperative crisis rate increased with the severity of preoperative MG and the prescription dose of anticholinesterase.Complete follow-up information of patients more than 12 months after the thymectomy was obtained on 151 cases,89 cases from the VATS group and 62 cases from the open group,with a mean follow-up period of 59.3 months,range from 12 to 117 months.Complete stable remission (CSR) was the end point for evaluation of the treatment results.The overall five-year CSR rate was 57.5％ Two good prognostic factors were identified; preoperative prescription of anticholinesterase alone (P=0.035) and non-thymomatous MG (P=0.003).The five-year CSR rate of the ocular type of MG reached a high level of 67.4％.Conclusions Thymectomy can achieve good long-term CSR in MG,and VATS is an ideal alternative method.High-dose prescription of anticholinesterase and the advanced stage by Myasthenia Gravis Foundation of America (MGFA) classification have higher risks of postoperative crisis.Preoperative prescription of anticholinesterase alone and non-thymomatous MG are good prognostic factors.Thymectomy should also be considered for the ocular type of MG.

Objective To evaluate the left ventricular (LV) radial and longitudinal systolic function in hypertrophic cardiomyopathy (HCM) patients by 3.0 T MR.Methods Sixteen HCM (HCM group) and twenty normal adults (normal group) were examined with fast imaging employing steady-state (FIESTA) acquisition sequence of cardiac MRI.LV ejection fraction (LVEF),longitudinal shortening (LS)and fractional shortening (FS)in three standard levels were measured to analyze LV radial and longitudinal systolic function.Results Asymmetric hypertrophy was detected in all HCM patients.The LVEF and FS were significantly higher while LS was significantly lower in HCM group than those in normal group(P ＜ 0.05or 0.01).FS at basal and middle levels were significantly higher in HCM group than in normal group (both P ＜0.01).FS in apex level was similar in the two groups(P =0.057).Pearson correlation analysis showed that LS was negatively related with the number of hypertrophy segments in HCM patients (r =-0.537,P =0.032).But there was no correlation between FS and the number of hypertrophy segments as well as FS and LS in HCM patients (r =-0.090,P =0.739 ; r =0.049,P =0.856).Conclusion The LV longitudinal systolic function was reduced but the LV radial systolic function remained unchanged in HCM patients,thus,LS changes could better reflect myocardial systolic function in HCM patients.

Objective To observe serum uric acid (UA) level distribution and explore risk factors of hyperuricemia (HUA) in a large cohort of active and retired employees underwent physical examination.Methods Physical examination was arranged for 21 700 active and retired employees from May 2010 to September 2011,16 416 employees were examined and complete examination data were obtained in 14 044 subjects.The distribution characteristics of UA level and correlations of UA level and HUA prevalence rate with gender,age,body mass index (BMI),systolic pressure (SBP),diastolic pressure (DBP),fasting blood-glucose (FPG),serum total cholesterol (TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C) were analyzed.Results HUA prevalence rate was 11.2％ in this cohort,which was significantly higher in males (15.8％) than in females (4.1％,P ＜ 0.05).The UA level and the HUA prevalence rate presented a “J” curve relationship with aging and positively correlated with BMI,SBP,DBP,TG,LDL-C,TC and FPG while negatively correlated with HDL-C.Multiple linear regression analysis showed that SBP,BMI,FPG,TG,and LDL-C were independent risk factors while HDL-C and female gender were the protective factors of HUA(all P ＜0.01).Aging and high DBP were independent risk factors of HUA for females (all P ＜ 0.05)and LDL-C was risk factor of HUA for males (P ＜ 0.05).Conclusions Serum UA level presents a “J” wave relationship with aging.The risk factors of HUA are increased SBP,BMI,FPG,TG,LDL-C while the protective factors of HUA are female gender and high HDL-C.

OBJECTIVESTo observe the clinical outcome of invasive thymoma, and analyze how the surgical methods, Masaoka staging, adjuvant radiotherapy and/or chemotherapy affect the prognosis.

METHODSThe clinical data of 59 surgical patients with invasive thymoma and conducted follow-up from January 2000 to December 2009 was analyzed retrospectively. There were 34 male and 25 female, aged from 18 to 72 years with a mean age of 49 years. Forty-four cases underwent radical resection while the other 15 cases underwent palliative resection or biopsy. Masaoka staging: 18 cases with stage II, 30 cases with stage III, 11 cases with stage IV. Patients with stage II didn't undergo further adjuvant radiotherapy or chemotherapy after surgery. Among the patients with stage III and stage IV, 26 patients received adjuvant radiotherapy and/or chemotherapy after surgery, while the other 15 patients did not receive any further therapy. The relationship between the prognosis and the different surgical methods, Masaoka staging, adjuvant radiotherapy and or chemotherapy was evaluated.

RESULTSFifty-nine patients had been followed up for 1 to 111 months with an average of 54 months. Three cases were lost with the rate of 6.1%. Nineteen patients suffered local recurrence or systemic metastasis, and 14 of them died. The 3-year and 5-year survival rates were 86.8% and 70.8% respectively. Univariate analysis indicated that patients with early Masaoka staging and who received radical resection, adjuvant radiotherapy and/or chemotherapy after surgery had better survival (P < 0.05). Multivariate analysis indicated that radical resection, adjuvant radiotherapy and or chemotherapy were the most significant prognostic factors which could remarkably improve the survival of patients (P < 0.05). For patients with resectable recurrence, reoperation could also improve survival.

CONCLUSIONSThe Masaoka staging is related to the prognosis of patients with invasive thymoma. Radical resection, adjuvant radiotherapy, chemotherapy can significantly improve the survival of patients with invasive thymoma. Reoperation can improve the survival of some patients with recurrence.
