Objective To compare the clinical results of the ureteral reimplantation with the traditional open approach and laparcocopic pneumovesical approach. Methods A retrospective review of 108 patients who underwent ureteral reimplantation from December 2004 to October 2010 was conducted.The patients were divided into open and pneumovesical groups according to the surgical approach.Perioperative results were compared between the two groups in terms of operative time,postoperative intravenous antibiotics duration,catheterization duration,postoperative stay,average total cost and surgical cost,respectively.And the pneumovesical group was divided into two stages by time,compared the operative time of the two stages and between the later stage and the open group. Results The postoperative hospital stay of pneumovesical group was shorter than the open group (6.8 ± 1.9 d and 8.9 ± 2.9 d,P =0.002 ).For catheterization duration,the pneumovesical group was shorter than the open group as well (5.2 ± 1.2 d and 6.2 ±2.2 d,P=0.057).For the postoperative intravenous antibiotics duration,the pneumovesical group was 5.0 ± 1.3 h,the open group was 5.4 ±1.6 h (P =0.159).For the total cost,the pneumovesical group was 16 067.9 ±4 295.8 RMB,the open group was 15 617.7 ± 5 486.5 R MB (P =0.168).For the surgical cost,the pneumovesical group was 9369.4 ± 1366.6 RMB,the open group was 7397.9 ± 1797.3 RMB ( P =0.083 ).Operative duration of the pneumovesical group and open group were 3.2 ± 1.1 h and 2.3 ± 1.1 h ( P =0.003).For pneumovesical group,the mean operative durations of the two stages were 3.6 h and 2.8 h (P =0.286).And the later stage of pneumovesical group was a little longer than the open group,but no significant difference ( P =0.234 ).No major complication was found in the 2 groups during the operative time and the postoperative hospital stay.Twenty-four patients (38 ureters) of the pneumovesical group were followed up with micturating cystourethrography ( MCU),ureterovesical reflux recurred in 3 patients.Two patients changed from grade Ⅲ to grade Ⅰ and 1 patient changed from grade Ⅴ to grade Ⅲ after the surgery.Five patients (9 ureters) of the open group were followed up,1 patient found bladder diverticulum; 1 patient found ureteral stricture 6 months after the surgery and got improved after secondary ureteral relimplantation surgery. Conclusions The pneumovesical approach is shorter than the open group in postoperative hospital stay and catheterization reserved duration.The pneumovesical approach is a safe and effective option for ureteral reimplantation.

Objective:To summarize the clinical characteristics of patients with coronavirus disease 2019 (COVID-19) infected with Delta variant, so as to provide further references for clinical diagnosis and treatment.Methods:A real-world study was conducted to analyze the characteristics of 166 COVID-19 patients infected with Delta variant at Guangzhou Eighth People’s Hospital, Guangzhou Medical University.Results:The study enrolled 5 asymptomatic cases, 123 non-severe cases (mild and moderate type), and 38 severe cases (severe and critical type). Among these patients, 69 (41.6%) were male and 97 (58.4%) were female, with a mean age of 47.0±23.5 years. Thirty-nine cases (23.5%) had received 1 or 2 doses of inactivated vaccine. The incidence of severe COVID-19 cases was 7.7% in 2-doses vaccinated patients, which was lower than that of 11.5% in 1-dose and 26.8% in unvaccinated patients. The proportion of severe cases in 2 dose-vaccinated patients was 7.7%, which was lower than that of 11.5% in 1-dose vaccinated patients and 26.8% in unvaccinated patients, but the difference was not significant ( P>0.05). The most common clinical symptom was fever (134 cases, 83.2%), and 39.1% of cases presented with high-grade fever (≥39 °C); other symptoms were cough, sputum, fatigue, and xerostomia. The proportion of fever in severe cases was significantly higher than that of non-severe cases (97.4% vs. 76.4%, P<0.01). Similarly, the proportion of severe cases with high peak temperature (≥39 ℃) () was also higher than that of non-severe cases (65.8% vs. 30.9%, P<0.01). The median minimal Cycle threshold (Ct) values of viral nucleic acid N gene and ORFlab gene were 20.3 and 21.5, respectively, and the minimum Ct values were 11.9 and 13.5, respectively. Within 48 h of admission, 9.0% of cases presented with decreased white blood cell counts, and 52.4% with decreased lymphocyte counts. The proportions of increased C-reactive protein, serum amyloid A, interleukin 6, and interleukin 10 were 32.5%, 57.4%, 65.3%, and 35.7%, respectively. The proportions of elevated C-reactive protein, serum amyloid A and interleukin-6 in severe cases were significantly higher than those in non-severe cases ( P<0.01). Logistic regression analysis showed that older age and higher peak temperature were associated with a higher likelihood of severe cases ( OR>3, 95% CI: 2-7, P<0.01). In terms of treatment, traditional Chinese medicine (TCM) was used in 97.6% of non-severe cases and 100% in severe cases. Other treatments included respiratory and nutritional support, immunotherapy (such as neutralizing antibodies and plasma of recovered patients). The median times from admission to progression to severe cases, of fever clearance, and of nucleic acid conversion were 5 days, 6 days and 19 days, respectively. No deaths were reported within 28 days. Conclusions:The symptoms of Delta variant infection in Guangzhou are characterized by a high proportion of fever, high peak temperature, long duration of fever, high viral load, a long time to nucleic acid conversion, and a high incidence of severe cases. The severe cases exhibit a higher percentage of elderly patients, a longer duration of fever and have a higher fever rate and a higher hyperthermia rate than non-severe cases. Age and hyperthermia are independent risk factors for progression to severe disease. The combination of TCM and Western medicine can control the progression of the disease effectively.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.
