Objective To evaluate the effect of the water-saving irrigation project on Oncomelania hupensis snail control in hilly regions of Yixing City, Jiangsu Province. Methods A retrospective survey combined with cross-sectional investigation was employed. The implementation of the water-saving irrigation development project in Yixing City from 2005 to 2007 was retrospectively collected, and the snail status was collected in regions where the water-saving irrigation project was located and the project-affected regions from 2003 to 2018, to examine the effect of the project on snail control. In addition, a cross-sectional survey was performed to investigate the destruction of the water-saving irrigation project in 2018. Results A total of 22 water-saving irrigation projects were implemented in 5 townships in hilly regions of Yixing City from 2005 to 2007, where snail habitats were treated covering 266.97 hm2. Before the implementation of the project from 2003 to 2006, cumulative 47.87 hm2 snail habitats were detected in regions where the project was located, and no snails were found in regions where the project was located from the implementation of the project in 2006 to 2018. However, a few snails were found in the project-affected regions in 2017 and 2018. In addition, there were problems found in the later-stage maintenance and management of the project. Conclusions The water-saving irrigation projects shows a high efficiency on snail control in hilly regions of Yixing City. The later-stage maintenance of the project and monitoring of snails remain to be intensified to enhance the snail control efficiency of the water-saving irrigation project.

Surveillance of echinococcosis in Yixing City from 2011 to 2018 / 中国血吸虫病防治杂志

Objective To analyze the results of echinococcosis surveillance in Yixing City from 2011 to 2018, so as to provide insights into echinococcosis control in the city. Methods All echinococcosis cases reported in Yixing City since 2007 that were captured from the China National Notifiable Infectious Disease Reporting Information System of Chinese Center for Disease Control and Prevention received a case study, and serological test and transabdominal B-mode ultrasound screening were performed among permanent residents and mutton market workers in Fangdong and Fangzhuang villages of Yixing City from 2011 to 2018. The cyst, mass and tubercle were detected in the liver and lung of the sheep from the mutton markets, and the Echinococcus coproantigen was detected in the canine stool samples from Fangdong and Fangzhuang villages. In addition, the awareness of echinococcosis prevention and control knowledge was investigated in the two villages using a questionnaire survey from 2011 to 2018. Results A total of 7 cases with echinococcosis had been reported in Yixing City since 2007, with prevalence of 0.56/100 000, and all cases were E. granulosus-infected patients, including 2 cases with a history to travel to echinococcosis-endemic areas and 5 cases with a history of working in local mutton markets or dog contacts. From 2011 to 2018, a total of 1 861 residents received serological tests, with 0.54% seropositivity, and no seropositives were detected since 2016. Among the 1 807 individuals receiving transabdominal B-mode ultrasound screening, suspected cysts were found in 143 individuals (7.91%), and 1.40% (2/143) seropositivity was detected in these individuals. The mean positive rate of the Echinococcus coproantigen was 0.67% (3 /446) in the canine stool samples. Among the 4 010 sheep liver and lung specimens sampled from the mutton markets, 7 specimens (0.17%) were detected with cysts or tubercles. In addition, the mean awareness rate of echinococcosis prevention and control knowledge was 76.95% among the 538 subjects receiving questionnaire surveys from 2011 to 2018, and the overall awareness appeared a tendency towards a rise year after year. Conclusions Although the prevalence of echinococcosis and the seropositivity of anti-Echinococcus antibodies are low, there is still a risk of transmission of echinococcosis in Yixing City. The surveillance of echinococcosis should continue to be intensified and related control interventions are required.

Combination of single-port thoracoscopy and laparoscopy for the treatment of esophageal carcinoma: report of 6 cases / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To study the feasibility and early results of radical resection of esophageal carcinoma using single-port thoracoscopy combined with laparoscopy.</p><p><b>METHODS</b>From March 2010 to December 2010, 6 patients with esophageal carcinoma underwent radical resection by single-port thoracoscopy combined with laparoscopy in the General Hospital of People's Liberation Army. With the patients at a supine position, laparoscopy was performed to complete stomach mobilization and abdominal lymph node dissection. Thoracoscopy was then carried out with the patients lying on the left to mobilize the esophagus and dissect thoracic lymph nodes. Finally, the stomach was pulled into the thoracic cavity via the hiatus of the diaphragm to construct a tube-like stomach, which was then anastomosed to the esophagus using the OrVil system.</p><p><b>RESULTS</b>No patient was converted to open surgery during the operation. The total operative time ranged from 200 to 320 min. The mean laparoscopic time was 75(range, 45-90) min, and the mean thoracoscopic time 160(120-240) min. The mean intraoperative blood loss was 220(160-300) ml. The mean lymph node retrieval was 12(9-18). No anastomotic fistula, chylothorax, lung infection were found postoperatively.</p><p><b>CONCLUSION</b>After esophageal resection using single-port thoracoscopic and laparoscopy, reconstruction using OrVil system is safe and feasible.</p>

Rhinoplasty in Chinese: management of lower dorsum and bulbous nasal tip / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Bulbous nasal tips and lower dorsa are common facial features in Chinese people, and surgery to reshape these is frequently requested. The use of silicone implants in rhinoplasty has been widely used in China for many years, but is not suitable for patients seeking Caucasian tip shapes. The creation of an excessively high tip supported only by a silicone implant inevitably leads to implant extrusion. Although many rhinoplasty techniques have been used in Caucasian patients, there is currently no suitable method for Chinese patients, whose anatomy differs from that of Caucasians. The present study was aimed to investigate the clinical outcome of a novel method of rhinoplasty in Chinese people.</p><p><b>METHODS</b>Eighty patients underwent rhinoplasty using our method between 2002 and 2006. We classified the patients into three types, according to the distance between tip defining points, and used different techniques accordingly. Furthermore, an innovative cartilage carving method and a tip fibro-fatty tissue flap were designed and combined with traditional techniques, such as insertion of silicone implant, cartilage grafts, suture techniques and cephalic trimming to reshape the nasal contours. The followup period was 10 - 60 months (average, 21 months).</p><p><b>RESULTS</b>Remarkable modifications in nasal contours were achieved. No complications developed in any of the 80 patients. Seventy-eight patients were satisfied with the results. The outcomes remained unchanged over time.</p><p><b>CONCLUSION</b>Our method is effective and suitable for the treatment of Chinese patients with lower dorsa and bulbous nasal tips.</p>

Clinical characteristics and outcome of myasthenia gravis with and without thymoma after operation / 中华外科杂志

<p><b>OBJECTIVE</b>To explore the clinical characteristics and outcome of myasthenia gravis with and without thymoma after operation.</p><p><b>METHODS</b>Two hundred and forty-three patients with myasthenia gravis surgically treated in our department from 1978 to 2003 were studied retrospectively. The clinical characteristics, complication, remission and survival were compared between myasthenia gravis with and without thymoma.</p><p><b>RESULTS</b>The patients of myasthenia gravis with thymoma were significantly older (t = 6.138, P = 0.000), had shorter duration of symptom (t = 3.783, P = 0.000), and also had higher myasthenia crisis rates after operation (chi(2) = 64.77, P = 0.000) than those of myasthenia gravis without thymoma. No differences of Osserman classification was found between the two groups (chi(2) = 7.678, P = 0.104). The complete remission rates and partial remission rates of myasthenia gravis with thymoma were significantly lower than those of myasthenia gravis without thymoma at 1 and 3 years (P = 0.049, P = 0.000; P = 0.015, P = 0.010), but no differences at 5 year (P = 0.457; P = 0.699). The survival rates of MG with thymoma were lower than that of MG without thymoma (Log-rank = 18.58, P = 0.000).</p><p><b>CONCLUSIONS</b>The clinical characteristics are different between myasthenia gravis with and without thymoma. The remission of symptom of myasthenia gravis with thymoma is worse than that of myasthenia gravis without thymoma in the near future, but is similar in the long future. The death rates of MG with thymoma is significantly higher than that of MG without thymoma.</p>

Expression of epidermal growth factor receptor in thymoma and its clinical significance / 第三军医大学学报

Objective　To study the effect of epidermal growt h factor receptor(EGFR) on the development and progress of thymoma. Me thods Expression of EGFR was detected by immunohistochemical stain in t he tissues of 11 cases of normal thymus and 29 cases of thymoma. Result s　 The positive expression of EGFR was 75.9%(22/29) in thymomas and 18.2%(2/11) in normal thymus. The difference was significant(P<0.01). The positive rate of EGFR was higher in invasive thymomas than in non-invasive ones (P<0.01). T he positive rate of EGFR increased with Masaoka stage with a significant increm ent in Ⅲ-Ⅳ stage compared with I stage (P<0.01). EGFR was strongly expre ssed in 5 cases of invasive thymomas, in which recurrence or metastasis occurred in 3 during the follow-up period after operation. But there was no statistical correlation with whether complicated with myasthenia gravis (MG) and histolog ical type. Conclusion　EGFR might be related to the tumori genesis and development of thymoma. There is high risk of recurrence and metast asis in case of EGFR over-expression and radiotherapy, chemotherapy and follow up should be enhanced.
