[Abstract ] Objective Clinically, the necessity of acid suppression treatment in vocal leukoplakia is still controversial .This paper aims to investigate the roles of LPR in the pathogenesis and pathological process of vocal leukoplakia , and to clear the signifi-cance of acid suppression in the treatment of this disease through observing the influence of laryngopharyngeal reflux ( LPR) on the symptoms of postoperative vocal leukoplakia . Methods We collected 97 cases underwent vocal leukoplakia surgery from June 2013 to December 2015 in the Department of Otorhinolarygology Head and Neck Surgery , Nanjing General Hospital of Nanjing Military Re-gion.According to the results of ambulatory 24-hour double probe ( simultaneous esophageal and pharyngeal ) pH monitoring ( pH-me-try), the patients with vocal leukoplakia were divided into LPR group (n=26, laryngopharyngeal reflux) and non-LPR group(n=71, non-laryngopharyngeal reflux).Meanwhile, the patients in LPR group were then randomly divided into acid-suppressing group(n=13, oral esomeprazole ) and non-acid-suppressing ( n=13, oral placebo ) . All patients received evaluation and compared by electrolaryngendo-scope, voice handicap index-10 ( VHI-10), reflux symptom index ( RSI) and reflux finding score ( RFS) before operation and 8 weeks after operation, and observe the effect of laryngopharyngeal reflux and acid suppression on the symptoms of postoperative vocal leukoplakia . Results RSI and RFS after operation were significantly lower than before operation in LPR group[(13.6±5.8) vs (18.2±6.2), (9.2±2.4) vs (10.6±2.8), P<0.05].The difference of RSI and RFS between before and after operation in LPR group was higher than the non-LPR group[(5.8±1.4) vs (2.3±0.8), (1.2±0.6) vs (0.5±0.2), P<0.05].The difference of RSI and RFS between before and after operation in acid-suppressing group was higher than the non-acid-suppressing group[(6.6±1.2) vs (0.8±0.6), (2.6±0.6) vs (0.5±0.3), P<0.05].VHI-10 after operation was significantly lower than before operation in acid-suppressing group[(12.6±3.6) vs (15.2±4.2), P<0.05] Conclusion Standard PPI administration to patients suffering from vocal leukoplakia accompanied with LPR can alleviate the symptoms of LPR and improve hoarseness .

OBJECTIVETo analyze and summarize the clinical features and experience in surgical treatment of deep sternal infection (DSWI).

METHODSThis was a retrospective study. From January 2008 to December 2013, 189 patients with secondary DSWI after cardiac surgery underwent the pectoralis major muscle flap transposition in our department. There were 116 male and 73 female patients. The mean age was (54 ± 21) years, the body mass index was (26. 1 ± 1. 3) kg/m2. The incidence of postoperation DSWI were after isolated coronary artery bypass grafting (CABG) in 93 patients, after other heart surgery plus CABG in 13 patients, after valve surgery in 47 patients, after thoracic aortic surgery in 16 patients, after congenital heart disease in 18 patients, and after cardiac injury in 2 patients. Clean patients' wound and extract secretions, clear the infection thoroughly by surgery and select antibiotics based on susceptibility results, and then repair the wound with appropriate muscle flap, place drain tube with negative pressure. Of all the 189 patients, 184 used isolate pectoralis, 1 used isolate rectus, and 4 used pectoralis plus rectus.

RESULTSThe operative wounds of 179 patients were primary healing (94. 7%). Hospital discharge was postponed by 1 week for 7 patients, due to subcutaneous wound infection. Subcutaneous wound infection occurred again in 8 patients 1 week after hospital discharge, and their wounds healed after wound dressing. Nine patients (4. 7%) did not recover, due to residue of the sequestrum and costal chondritis, whom were later cured by undergoing a second treatment of debridement and pectoralis major muscle flap transposition. Eight patients died, in which 2 died of respiratory failure, 2 died of bacterial endocarditis with septicemia, 2 died of renal failure, 1 died of intraoperative bleeding leading to brain death and the 1 died of heart failure. The mortality rate was 4. 2% . The average length of postoperative hospital stay was (14 ± 5) days. The longest postoperative follow-up period was 40 months, the median time was 26 months, the follow-up rate was 83. 9% . Totally 179 patients were no-reinfected, 2 patients were reinfected because of artificial vascular rejection.

CONCLUSIONTo perform surgical debridement and then reconstruct the sternal defect with pectoralis major muscle flap actively for the patient is an effective measure to improve patient's survival rate.

Objective To investigate the influence of intraoperative thermostasis over respiratory burst of polymorphonuclear neutrophils (PMNs) in patients undergoing radical operation for lung cancer.Methods Thirty-two ASA Ⅱ or Ⅲ patients scheduled for radical operation for lung cancer under general anesthesia were randomized into two groups ( n = 16 each): control group (Group C) and warming group (Group W). The patients in Group C were kept warm by routine measures such as using woollen blankets, while the patients in Group W were kept warm by force-air warming system and fluid warming device as soon as the patients were admitted to the operation room. Rectal and axillary temperatures were continuously monitored as the core and surface temperature, respectively. The core temperature was maintained at the preoperative level (baseline). Anesthesia was induced with midazolam, fentanyl and propofol. Tracheal intubation was facilitated with rocuronium. Anesthesia was maintained with isoflurane and nitrous oxide and intermittent i.v. boluses of fentanyl, midazolam and vecuronium. Venous blood samples were obtained before, during and at the end of surgery for normal blood analysis and respiratory burst of PMNs which included activated PMNs count and reactive oxygen species (ROS) production.Results (1) WBC and PMN counts were significantly increased during and after operation as compared with the baseline values before operation in both groups and there was no significant difference in WBC and PMN counts between the two groups. (2)Phorbol-12-myristate-13-acetate (PMA) stimulation resulted in higher intraoperative and postoperative activated PMN counts in both groups and higher postoperative ROS production in Group W. Postoperative ROS production was significantly higher in Group W than in Group C. (3) The PMN counts without stimulation activation during operation and intra- and post-operative ROS production were significantly decreased as compared with the baseline values before operation in Group C, while in Group W there was no significant difference in pre-, intra- and post-operative activated PMN counts and ROS production. The intraoperative PMN counts and intra- and post-operative ROS productions were significantly higher in Group W than in Group C.Conclusion Intraoperative thermostasis can effectively maintain activated PMN count and ROS production without stimulation and enhance ROS production with stimulation in patients undergoing radical operation for lung cancer.

Objective:To investigate the inhibiting and apoptosis-effects inducing of the recombinant Ganoderma Lucidum immunoregulatory protein(rLZ-8) on HL60 cells.Methods:HL60 cells were cultured and the inhibited rate of HL60 cells was measured by means of MTT assay.Apoptosis rate was detected with annexinV/PI.The Calcium ion level was analyzed by Fluo-3/AM stain.Caspase-3 activity was assessed by caspase-3 colorimetric assay.Results:The experiments indicated that rLZ-8 could induce the HL60 cells apoptosis.The calcium ion level was increased and caspase-3 activity elevated in HL60 cells after treated by rLZ-8.Conclusion:rLZ-8 could inhibit the proliferation and induce apoptosis of HL60 cells efficiently.The mechanism may be related to increased calcium ion level and elevation of caspase-3 activity.

Objective To compare the clinic characteristics, recurrences and prognosis in patients with stage Ⅰ bronchioloalveolar carcinoma (BAC) and adenocarcinoma of the lung. Methods The data of 56 patients with stage Ⅰ BAC and 169 patients with stage Ⅰ adenocarcinoma were analyzed retrospectively. Results The overall 1-, 3-, 5- year survival rates were 94.7%, 83.5% and 61.2%, respectively. Compared with adenocarcinoma of the lung, BAC showed a better survival rate(x2 =6.36, P =0.012). After surgery patients with BAC were prone to develop intrathoracic recurrence, and adenocarcinoma was equal between intrathoracic recurrence and extrathoracic metastasis. The rate of intrathoracic recurrence and extrathoracic metastasis between BAC and adenocarcinoma was significantly different (14/16 vs. 27/59, x2 =8.85, P=0.004). In both group, preoperative asymptomatic patients had better survival rate(x2 = 7.28, P = 0.007; x2 = 6.07, P = 0. 014). Univariate analysis indicated that sex, age(< 60 years and ≥60 years), location of tumor and smoking history did not significantly influence survival in patients with stage Ⅰ BAC or adenocarcinoma (P > 0.05). Conclusion The prognosis of stage Ⅰ BAC is superior to that of stage Ⅰ adenocarcinoma. BAC is prone to develop intrathoracic recurrence, and adenocarcinoma is equal between intrathoracic recurrence and extrathoracic metastasis. Early diagnosis of lung cancer could improve long-term survival.

Traditional Chinese medicine (TCM) is considered an important complementary therapy with beneficial effects for cancer patients. Elderly patients with non-small-cell lung cancer (NSCLC) are a complex patient group with increasing co-morbidity and shrinking physiological reserve, and may derive substantial benefit from the supportive aspects of TCM. Researchers from Shanghai Longhua Hospital found that qi and yin deficiency is a common syndrome in patients with stage III or IV lung cancer. This project was designed to study the combination of single-agent chemotherapy with TCM methods of benefiting qi and yin in elderly patients with advanced NSCLC.

Objective: To investigate the association of physical activity and screen time with overweight and obesity among children and adolescents with special needs in Tianjin, so as to provide scientific evidence for childhood obesity prevention and intervention measures in the population. Methods: From January 2022 to June 2024, 296 children and adolescents with intellectual disabilities and autism spectrum disorders aged 2-18 years were recruited from special education schools and institutions in Tianjin. Height and weight were measured, and a standardized questionnaire was used to assess physical activity and screen time. Binary Logistic regression analysis was carried out to investigate the association of physical activity and screen time with overweight and obesity. Results: The prevalence of overweight and obesity among children and adolescents with special needs in Tianjin were 17.2% and 21.6%, respectively, and the combined prevalence of overweight and obesity was 38.9%. The median of moderatetovigorous physical activity (MVPA) time was 0.20 h/d, and physical activity sufficiency rate was 7.8%. The median of screen time was 1.79 h/d, and the screen time compliance rate was 68.2%. The binary Logistic regression results showed that lower levels of MVPA time and increased screen time were associated with a higher risk of overweight and obesity among children and adolescents with special needs [OR(95%CI)=1.80(1.06-3.07), 2.40(1.42-4.07),P<0.05]. Conclusions Insufficient physical activity and excessive screen time are associated with an increased risk of overweight and obesity among children and adolescents with special needs. Therefore, comprehensive intervention measures should be implemented as early as possible to prevent and reduce the incidence of overweight and obesity in this population.

Objective To observe the effects of Huoxue Digui Decoction on iron accumulation and ferroptosis in renal podocytes of diabetic nephropathy(DN)mice.Methods Totally 50 C57BL/6J mice were randomly divided into normal group(6 mice)and modeling group(44 mice).The DN model was established by streptozotocin injection.Mice conforming to DN model were randomly divided into model group(8 mice),and sulforaphane group,Huoxue Digui Decoction low-,medium-and high-dosage groups(6 mice for each group).The sulforaphane group was injected with sulforaphane intraperitoneally,while Huoxue Digui Decoction low-,medium-and high-dosage groups were orally administered with corresponding solution for 12 consecutive weeks.The fasting blood glucose,blood urea nitrogen,serum creatinine,24 h urinary albumin were detected,HE staining was used to observe the morphology of renal tissue,PAS staining was used to observe glycogen deposition in renal tissue,Masson staining was used to observe fibrosis in renal tissue;transmission electron microscopy was used to observe the ultrastructure of renal tissue,immunohistochemistry was used to detect the expressions of Podocin and Nephrin in renal tissue,Western blot was used to detect the protein expressions of glutathione peroxidase 4(GPX4),ACSL4,nuclear factor E2 related factor 2(Nrf2)and ferroportin 1(FPN1)in renal tissue,Prussian blue staining was used to observe the deposition of ferric ion in renal tissue.Results Compared with the normal group,the fasting blood glucose,blood urea nitrogen,serum creatinine and 24 h urinary albumin in model group significantly increased(P<0.01),with renal tissue capillary atrophy,increased glycogen deposition,and worsening fibrosis,the expressions of Podocin and Nephrin in renal tissue were down-regulated,while the expressions of GPX4,Nrf2 and FPN1 protein were significantly decreased(P<0.01),the expression of ACSL4 protein significantly increased(P<0.01),and the deposition of ferric ion in renal tissue increased.Compared with the model group,the fasting blood glucose,blood urea nitrogen,serum creatinine and 24 h urinary albumin in sulforaphane group and Huoxue Digui Decoction groups were reduced to different degrees(P<0.05,P<0.01),renal tissue pathological damage was reduced to varying degrees,glycogen deposition was reduced,and fibrosis was alleviated,the expressions of Podocin and Nephrin in renal tissue were up-regulated,while the expressions of GPX4,Nrf2 and FPN1 protein significantly increased(P<0.01),the expression of ACSL4 protein significantly decreased(P<0.05,P<0.01),and the deposition of ferric ion in renal tissue was reduced.Conclusion Huoxue Digui Decoction can alleviate renal pathological injury,reduce blood glucose and delay the progression of DN mice.The mechanism may be related to regulating the expressions of Nrf2 and FPN1,inhibiting iron accumulation and ferroptosis in renal podocytes of DN mice.

Chronic HBV infection is an important phase in the natural history of HBV, but there are still controversies over the treatment of this stage. Traditional Chinese medicine has had unique advantages in the prevention and treatment of viral hepatitis since ancient times and plays an important role in prevention and treatment of viral hepatitis in China. Based on the pathological process of chronic HBV infection, the team of Department of Hepatology in Shenzhen Hospital of Traditional Chinese Medicine believes that the core pathogenesis of chronic HBV infection is "kidney deficiency and epidemic toxin lurking in liver blood" and established kidney-tonifying therapy for the treatment of chronic HBV infection. Under the support of the project of Prevention and Treatment of Major Infectious Diseases such as AIDS and Viral Hepatitis in The Eleventh Five Year Plan, The Twelfth Five Year Plan, and The Thirteenth Five Year Plan, the team has conducted studies on the regularity of syndromes and a series of clinical studies and investigated the clinical efficacy of kidney-tonifying therapy through multicenter, randomized, double-blind, placebo-controlled studies, thereby exploring the application and mechanism of traditional Chinese medicine treatment in patients with chronic HBV infection. However, there are still difficulties in the pathogenesis and treatment of chronic HBV infection, and with the inheritance, innovation, and modernization of traditional Chinese medicine, it is believed that traditional Chinese medicine can provide reliable regimens for the treatment of chronic HBV infection.
