OBJECTIVE: To detect the expression of NGF, BDNF, NT-3 mRNA in the peripheral blood of patients with allergic rhinitis (AR). And to analyze the correlation between NGF, BDNF, NT-3 mRNA expression and the epidsode of rhinitis through Th-2 Hypothesis. METHOD: This study was a group controlled trial. The expression of NGF, BDNF and NT-3 mRNA were tested by real-time quantitative RT-PCR and the concentrations of IL-4, IL-6, IL-10 and INF-alpha were tested by ELISA. RESULT: The expression of NGF, BDNF and NT-3 mRNA in AR patients were 2.44, 4.46 and 1.78 times the amount of those in the healthy adults, respectively. The increased expression of NT-3 correlated positively with the scores of visual analog scale of AR. The concentrations of IL-4, IL-6 and IL-10, which were 2198 +/- 472 pg/mL, 9407 +/- 703 pg/mL and 3917 +/- 323 pg/mL respectively, were higher than those in the healthy adults. The concentration of INF-alpha was 2198 +/- 472 pg/mL and less than the healthy adults. The increased expressions of NGF, NT-3 were positively related to the increase of IL-4, IL-6 and IL-10. CONCLUSION The expressions of NGF, BDNF and NT-3 mRNA in AR patients are higher than those in the healthy adults. NGF, BDNF and NT-3 may contribute to the pathogenesis of AR. Moreover, NGF and NT-3 may induce the episode of rhinitis through Th-2 Hypothesis.

Objective To analyze the different approaches and their indications in the laparo-scopic treatment of upper urinary tract transitional cell carcinoma. Methods 94 patients with upper urinary tract transitional cell carcinoma were divided to two groups. Group A (63 cases) with renal pelvic and ugper ureteral carcinoma were treated with retroperitoneal approach laparoscopic surgery and transurethral reseetoscope surgery. Group B (31 cases) with middle ureteral carcinoma including 6 cases with ureteral local infiltration were treated through 70° recumbent position transperitoneal ap-proach laparoscopic surgery combined with bladder cuff resection. The operative time, blood loss, the intestinal functional recovery time and post-operative complications were recorded. Results All 94 procedures were successfully completed, with no complication during the surgery. The mean operation time of A and B group was 156.5 and 160.8 min;the mean blood loss was 80 and 86 ml; the mean hos-pital stay was 8 and 8. 5 d; the time of bowel functional recovery of group A and group B was 24-48 and 24-72 h, respectively. 84 cases were followed-up with mean follow-up time of 23 months. Three eases and 5 cases were found having bladder tumor in the group A and group B. The incision and port metastasis was not found. Conclusions It is safe and feasible to treat the upper urinary tract transi-tional cell carcinoma laparoscopically. The selection of operating approach is mainly based on the loca-tion and local infiltration status of the tumor.

Objective To evaluate the efficacy and safety of percutaneous nephrolithotomy (PCNL) under ultrasonic guidance for the treatment of upper urinary calculus. Methods From June 2004 to July 2009, 1289 patients with upper urinary tract calculi were treated with PCNL under ultrasonic guidance, 386 cases of them were upper ureteral calculi, 463 cases were single renal calculi,355 cases were multiple renal caculi, 85 cases were staghorn calculi. Calculus size was 0.8 cm× 1.2cm-9.0 cm× 5.3 cm,mean 2. 1 cm× 3.1 cm. Nine hunderd and thirty-five cases were with hydronephrosis. Results All patients were performed PCNL successfully, without conversion to open surgery or death. Mean operation time was 90(55-220)min, mean operative blood loss was 175(60-800)ml. Thirty-one cases were given blood transfusion during operation or post operation, 14 cases were given super-selective renal artery embolism for bleeding control. 1105 cases were treated with single tract, 108 cases with double tracts, 76 cases with three tracts. Calculus clearance rate of onestage PCNL was 85.03%(1096/1289);193 cases were found with residual calculi, 67 of them were given extracorporeal shock-wave lithotripsy, 126 of them were given two-stage PCNL, calculi were removed complelety in 85 cases. Total calculus clearance rate was 91.62%(1181/1289). Conclusions PCNL under ultrasonic guidance is an effective and safe method for the treatment of upper urinary calculus with advantages of accurate positioning, high calculus clearance rate, minimal trauma, and fewer complications. The key of successful PCNL is selection of patients, grasp of operation technique, and availability of other equipements.

Objective To compare the safety of laparoscopic live donor nephreetomy(LDN) and open live donor nephrectomy(ODN), evaluate the kidney function and blood pressure of living donors during 1 year follow-up. Methods Thirty cases of LDN and 30 eases of ODN were retrospectively reviewed. The operation time, warm ischemia time, operative blood loss, time to post-operative intake and time to ambulation of the 2 grouups were compared. According to the modified Clavien classifica-tion system procedure-related complications were described and compared. Serum creatinine(SCr) le-vels, blood pressure and 24-h urine protein excretion were measured before nephreetomy and 1 d, 7 d, 3 months, 6 and 12 months after nephrectomy. Glomerular filtration rate (GFR) were measured preo-pratively and at 6 and 12 months postoperatively. These data were statistically analyzed. Results The operation time was (98. 6+13. 6)rain and (96.3+19. 5)rain in the LDN and ODN groups, re- spectively. Warm ischemia time in the LDN group was (90.6±15.1)s, in the ODN group was (86.4±12.3)s. Operative blood loss was (105.2±634.8)ml and (206.3±126.4)ml in the LDN and ODN groups(P<0.01). For the time to post-operative intake and time to ambulation, LDN group was (28.5±2.9)h and (25.8±63.8)h, ODN group was (38.6±63.3)h and (36.5±65.3)h(P<0.01). Perioperative complications rates were 6.6%(2/30) and 23.3%(7/30) for LDN and ODN, respective-ly. SCr was (109.1±7.5), (105.4±69.5), (96.6±10.7), (89.4±11.5), (91.6±69.3)/zmol/L in the LDN group and (107.3±69.6), (103.3±68.4), (95.4±69.1), (90.5±13.6), (90.3±11.7)μmol/L in the ODN group 1 day, 7 days, 3 months, 6 months and 12 months after nephrectomy. The mean GFR of LDN and ODN was 64.7 and 65.8 ml/min at 6 months after nephrectomy, 65.9 and 67.5 ml/min at 12 months postoperatively, which were significantly different comparing with preoperative mean GFR in each group(P<0.05) but no significant difference was found between 6 months and 12 months after nephrectomy and between the 2 groups at the same time point respectively(P>0.05). Mean 24 h protein excretion was elevated after either LDN or ODN during 1 year followup, but was not significantly different either between predonation and 1 year after nephrectomy or between the 2 groups at the same period. Blood pressure increased or decreased slightly with the duration of follow-up,no significant blood presure changes were found before and after nephrectomy or between the two groups at the same period postoperatively. Conclusions LDN has the advantages of minimal trauma, less operative blood loss and quicker convalescence. It is safe and and has no adverse effects regarding kidney function and blood pressure during the first year after living kidney donation comparing to ODN.

Objective To investigate the effects of same calorie intake of different enteral nutrition (EN) on blood glucose in patients with mechanical ventilation.Methods A total of 60 critically ill patients who were admitted to the Department of Intensive Care Unit (ICU) of Taizhou Combined Traditional Chinese and Western Medicine Hospital and received mechanical ventilation from January 2015 to January 2017 were selected. According to the random number table method, the patients were divided into a control group and a study group, 30cases in each group. The patients in the control group were given EN suspension (nutrison fibre), patients in the study group received EN emulsion (fresubin diabetes), on the first day, 1/3 standard calorie was supplied, if the patient had no any discomfort, on the second day 1/2 standard heat was given, from the third day to the tenth day they took the full amount and achieved complete EN (TEN).The fasting blood glucose (FBG), 2 hours postprandial blood glucose (2 h PBG) and glycated hemoglobin (HbA1) level before and after the EN for 10 days were observed, the gastrointestinal tolerance, dosage of insulin, inflammation related indexes, the incidence of ventilator associated pneumonia (VAP) and fatality were analyzed in the two groups.Results Compared with those before EN support, the FBG and 2 h PBG were decreased after the support for 10 days in both groups, the dosage of insulin used was decreased, and the degrees of decrease were more marked in the study group than those in the control group [FBG (mmol/L): 8.03±1.69 vs. 8.87±1.75, 2 h PBG (mmol/L): 8.25±1.98 vs. 10.43±2.34, dosage of insulin (U/d): 38.02±3.24 vs. 40.87±3.48, allP < 0.05], but there was no statistical significant difference in HbA1 level between the two groups [(7.36±1.53)% vs. (7.37±1.29)%,P > 0.05]. The incidence of gastrointestinal intolerance was lower in study group than that in control group [6.67% (2/30) vs. 10.0% (3/30)], but there was no statistical significant difference between the two groups (P > 0.05). Compared with those before EN support, the levels of γ-interferon (IFN-γ) were significantly increased (P < 0.05), while the tumor necrosis factor-α (TNF-α), interleukins (IL-6 and IL-8) levels were significantly decreased after 10 days of EN support, but no statistical significant differences were found (allP > 0.05) between the two groups. During the treatment in the two groups, the incidence of VAP and mortality were relatively low, and there were no statistical significant differences were seen between the two groups (bothP > 0.05).Conclusions The blood glucose control of fresubin diabetes in patients with mechanical ventilation is superior to that of nutrison fibre, fresubin diabetes can reduce the dosage of insulin, decrease the levels of inflammatory factors and conducive to the prognosis of the patients.

Objective:To evaluate the efficacy of neoadjuvant chemoimmunotherapy (NACI) combined with transoral robotic surgery (TORS) in the treatment of locally advanced oropharyngeal squamous cell carcinoma (OPSCC).Methods:This was a retrospective study of 15 patients with locally advanced OPSCC who underwent TORS after neoadjuvant therapy (NAT) at the Department of Otolaryngology-Head and Neck Surgery of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from April 2019 to February 2023. There were 12 males and 3 females, aged 31 to 74 years. Twelve cases were tonsil cancer, and 3 cases were tongue base cancer. There were 11 cases in stage Ⅲ and 4 cases in stage Ⅳ. Two patients received neoadjuvant chemotherapy and 13 patients received NACI, with 2 to 3 cycles, and all patients underwent TORS after multidisciplinary team consultation. The clinicopathological characteristics, surgical outcomes, and oncological results were summarized.Results:All surgeries were successfully completed with negative surgical margins, and no case was required conversion surgery. All patients were fed via nasogastric tubes postoperatively, with a median gastric tube stay of 7 days (range: 2-60 days). No tracheotomy was applied. There were no major complications such as postoperative bleeding. Pathological complete response (pCR) was found in 10 cases (76.9%) among the 13 patients with NACI. The follow-up time was 21 months (range: 10-47 months), and there was no death or distant metastasis. One patient with rT0N3M0 tonsil cancer had local recurrence 5 months after surgery. The 2-year overall survival and 2-year disease-free survival were respectively 100.0% and 93.3% in the 15 patients.Conclusion:NACI combined with TORS provides a safe, effective and minimally invasive treatment for patients with locally advanced oropharyngeal squamous cell carcinoma.
