OBJECTIVE: To investigate the clinical features of fungal rhino-sinusitis. METHOD: Clinical data of 189 patients suffering from fungal rhino-sinusitis treated by functional endoscopic sinus surgery was analyzed retrospectively. The analyzed data included clinical type, age of onset, predilectionsite, reason, and surgical outcome. RESULT: Among the 189 patients with fungal rhino-sinusitis,181 cases were fungal ball,6 cases were allergic fungal rhino-sinusitis, 1 case was acute invasive fungnal rhino-sinusitis, 1 case was chronic invasive fungnal rhino-sinusitis. One hundred and twenty-eight cases were in the maxillary sinus (123 cases were unilateral, 5 cases were bilateral). Nineteen cases were in the ethmoid sinus. 31 cases were in the sphenoid sinus. Two cases were both in the maxillary sinus and ethmoid sinus, 1 case was both in the maxillary sinus and sphenoid sinus. Two cases invasive fungnal rhino-sinusitis had diabetes history. All the patients treated by functional endoscopic sinus surgery, 184 cases without recurrence, 5 cases suffered re-operation. CONCLUSION The incidence of fungal rhinosinusitis is showing a rising trend, fungal ball is the highest. The sinusitis patients whom we highly doubt for fungal infection should be confirmed by using sinonasal secretion smear, cultivation and histopathological examination. Surgical treatment should completely remove the fungal masses, to avoid reoperation.

OBJECTIVE To investigate drug resistance characteristice of Escherichia coli and Klebsiella pneumoniae producing extended-spectrum?-lactamases(ESBLs) in our hospital so as to instruct rational use of antibiotics in clinic. METHODS The ESBLs were determined by the sensitivity and confirming tests according to NCCLS(1999) standard. RESULTS The isolated ratio of ESBLs producing E. coli and K. pneumoniae increased from 28.6% and 29.2% in 2005 to 48.5% and 49.2% in 2007. Extended-Spectum ?-Lactamases germs showed high resistance to cephalosporins-1G, 2G, 3G, to Penicillin and to Am Aztreonam. The rate of sensitivity to imipenem was 100.0%. CONCLUSIONS There is an increasing trend of ESBLs producing E. coli and K. pneumoniae. The imipenem is the best drug for treatment the bacterium producing ESBLs.

Objective To understand the schistosomiasis control progress and endemic situation,so as to provide the evi?dence for formulating the strategy of schistosomiasis elimination in Sichuan Province. Methods The schistosomiasis history da?ta,working reports of schistosomiasis prevention and control,schistosomiasis surveillance data,and data of schistosomiasis pre?vention and control capacity were collected and analyzed for the schistosomiasis control progress and epidemic situation in Sich?uan Province from 2004 to 2015. Results There were 63 schistosomiasis endemic districts in 11 cities in Sichuan Province, and the standard of schistosomiasis transmission interruption was achieved in the whole province in 2015. Currently,the area with Oncomelania hupensis snails was 2 537.54 hm2,and there were 1 769 advanced schistosomiasis patients. From 2004 to 2015,the accumulated survey area with snails was 433 065.80 hm2,and the area of snail control by molluscicides was 251 259 hm2. There were 26.017 144 million person?times of schistosomiasis blood tests and 7.89 million person?times of chemotherapy. There were 1.276 117 million head?times of cattle that received the schistosomiasis examinations. The schistosomiasis patients and livestock and the area with snails were decreased year by year. Since 2010,there were no local schistosome?infected resi?dents and livestock and since 2004,there were no schistosome?infected snails. However,in some area,the professional person?nel were less,the technology and hardware lagged behind,and the schistosomiasis prevention and control capacity was weak. Conclusions Sichuan Province achieved the standard of schistosomiasis transmission interruption in 2015. In the future,the comprehensive schistosomiasis prevention and control strategy still should be strengthened,including the promotion of schistoso?miasis prevention and control capacity,establishment of sensitive early?warning surveillance system,and implementation of ac?curate schistosomiasis prevention and control,in order to consolidate the control achievements and realize the aim of schistoso?miasis elimination as soon as possible.

Objective To evaluate the intervention effect of Yi?Han bilingual health education of schistosomiasis control. Methods Baimiao Village in Daqing Town,Xichang City,where Yi Nationality inhabited,was chosen as a pilot to carry out Yi?Han bilingual health education of schistosomiasis control from 2012 to 2015. The villagers and students in the pilot area were in?vestigated by questionnaires before and after the intervention to understand their awareness and correct behavior status on schis?tosomiasis control. Results After the intervention of Yi?Han bilingual health education of schistosomiasis control for 3 years, the awareness rate and the correct rate of behavior on schistosomiasis control of the villagers in the pilot area improved from 45.79%and 51.12%in 2012 to 97.80%and 98.78%in 2015. As for the students,the two rates mentioned above improved from 64.16%and 60.83%in 2012 to 100%and 98.89%in 2015 respectively,and all the differences between the rates before and af?ter the intervention were statistically significant( all P<0.01). Conclusion The intervention of Yi?Han bilingual health educa?tion of schistosomiasis control can obviously improve the knowledge awareness rates and the correct rates of behavior of the resi?dents and students in the gathering area of Yi Nationality.

OBJECTIVE To investigate the clinical efficacy of microwave ablation in treating snoring and obstructive sleep apnea hypopnea syndrome(OSAHS). METHODS Eight patients with snores and 48 with OSAHS were included in the study. They all received micro-surgeries including plastic operations on the uvula and soft palate,tonsil ablation and tonsillectomy,inferior nasal concha and adenoid ablation,and de-volume of the tongue root. Symptoms six months before and after surgery were monitored by Polysomnography(PSG). RESULTS In 56 cases, the patients’ throats were widened. The mean values of the apnea hypopnea index(AHI), the lowest saturations (LSaO2) and the snoring index were significantly different before and after surgery(P

Objective:To investigate the preparation methods and quality control of 177Lu-labeled radiopharmaceuticals, and conduct preliminary clinical application research. Methods:177Lu-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (DOTA)- D-Phe1-Tyr3-octreotide (TOC) and 177Lu-prostate specific membrane antigen (PSMA)-I&T were labeled by manual labeling and automatic labeling, respectively. Factors such as the amount of precursor and nuclide, reaction temperature, pH value, reaction time, labeling yield and specific activity were investigated. Quality control of the products were carried out, such as clarity, pH value, sterility, bacterial endotoxin and stability in vitro. 177Lu-PSMA-I&T was applied to the treatment of prostate cancer patients, and the efficacy was evaluated by SPECT/CT imaging. Paired t test was used to analyze the data. Results:The amount of precursor and nuclide, reaction temperature, pH value and reaction time of the two methods were basically the same, both with high yield and specific activity. The yield of 177Lu-DOTA-TOC automatic labeling was significantly higher than that of manual labeling (99.2±0.4)% vs (95.3±1.5)% ( t=7.17, P<0.001), and the specific activity were (91.6±13.7) vs (89.1±13.2) GBq/μmol. The yield of 177Lu-PSMA-I&T automatic labeling was also significantly higher than that of manual labeling (99.6±0.3)% vs (95.7±1.3)% ( t=8.24, P<0.001), and the specific activity were (96.1±14.3) vs (93.2±13.8) GBq/μmol. The labeled products were colorless clear solution with pH value of 6.5-7.0. The sterility and bacterial endotoxin met the requirements. The radiochemical purity of the labeled products was more than 95% after 48 h, which showed good stability. The clinical application of 177Lu-PSMA-I&T in patients with prostate cancer showed that both primary and metastatic lesions had good uptake. Conclusions:The labeling of 177Lu radiopharmaceuticals is simple and has high yield and stability. The application of automatic labeling can simplify the process, improve the yield and reduce irradiation.
