Objective: To understand the development of nasopharyngeal carcinoma researches in worldwide, and to study the development feasibility of professional journal on nasopharyngeal carcinoma.Methods: The literatures on nasopharyngeal carcinoma were systematically retrieved from databases of SCI (Science Citation Index) from 1999 to 2012, and the data of publishing time, journal title, article type, language, research area, first author, correspondence author, district, and fund, etc were collected and bibliometricly analyzed.Results: An increasing trend of paper publication was detected, corresponding with linear and exponential growth pattern. Journal distribution was accordance with Brad Ford’s law; the literatures of nasopharyngeal carcinoma were assembling and parting distribution. The first author distribution conformed to Lotka’s law; whereas, the correspondence author distribution did not. Mainland China, Hong Kong and Taiwan occupied an important position in respect of first author, correspondence author and fund.Conclusion: Nasopharyngeal carcinoma study needs professional journals bearing a larger number of scientific research achievements, and journals run in China, where the Nasopharyngeal carcinoma incidences was reported the highest in the world, may promote the development of this subject.

Autoradiography of nicotinic acetylcholine receptors (N-AChR) with the application of histochemical staining location of cholinesterase was used to observe the effect of soman on junctional and extrajunctional N-AChR. Testing with the diaphragms and extensor digitorum longus muscles of mice and rats, we found that soman mainly increased the number of extrajunctional N-AChR. It did pot alter the number of junctional N-AChR significantly, nor did it have any pronounced effects on the glycoprotein property and isoelectric point (pI) of junctional and extrajunctional N-AChR. The change of extrajunctional N-AChR number caused by soman is similar to the phenomenon of increased extrajunctional N-AChR number and sensitivity resulting from denervation, but the mechanism of action is different from the latter. The increase of N-AChR number is one of the important characteristics of soman poisoning which make it different from other nerve agents. To maintain the metabolic balance of N-AChR may be an important new approach to the treatment of soman poisoning.

Extended liver resection may provide longterm survival in selected patients with hilar cholangiocarcinoma.In May 2013,a patient with hilar cholangiocarcinoma received right hemihepatectomy combined with caudate lobectomy under the guidance of precision hepatectomy technique.The porta hepatis was clamped in the operation for 3 times intermittently.The operation time was 8 hours,and the volume of intraoperative blood loss was 600 mL.The patient was discharged at postoperative day 14.The results of pathological examination confirmed that the patient had moderately-highly differentiated adenocarcinoma with full-thickness infiltration of the bile duct and tumorfree margins.No tumor recurrence was detected during the followup which was lasted for 6 months.The operation was carried out based on the three dimensional reconstruction,liver reserve function evaluation,intraoperative controlled low central venous pressure and precision hepatectomy technique,and the results were satisfactory.

Objective To evaluate safety and efficacy of a fractional microneedle radiofrequency device in the treatment of axillary osmidrosis.Methods A total of 24 patients with moderate to severe axillary osmidrosis were enrolled from Department of Dermatology of Peking Union Medical College Hospital between June 2015 and June 2016,and treated with the Body TiteTM fractional microneedle radiofrequency device for 1 session.Visual analogue scale (VAS) was used to evaluate the intensity of axillary odor in patients,36-item short-form health survey (SF-36) to assess health-related quality of life (HRQoL),and axillary skin tissues were resected for histopathological examination before and after the treatment.Results VAS showed that 22 of 24 patients achieved persistent remission for more than 12 weeks,and rates of decrease in odor score ranged from 50％ to 100％.However,1 patient experienced recurrence at 12 weeks after the treatment,and another 1 patient did not achieve clinical remission.SF-36 revealed that scores of social functioning (SF),role-emotional (RE) and mental health (MH) scales were all significantly increased after the treatment [M (P0-P100):100.00 (62.00-112.50),100.00 (33.30-110.00),68.00 (48.00-80.00),respectively] compared with those before the treatment [77.50 (62.50-100.00),66.67 (33.30-100.00),55.00 (48.88-72.00),respectively,all P ＜ 0.05].Histopathological examination showed obvious degeneration and necrosis of sweat gland cells in 22 cases,and epidermal damages in 2 patients after the treatment.Unilateral upper-limb pain occurred in 1 case,and small-area burn-like skin changes were observed in 2 cases after the treatment.The postoperative recovery time ranged from 7 to 14 days.Conclusion The fractional microneedle radiofrequency device has shown high clinical response rate,good safety,and favorable application prospects in the treatment of axillary osmidrosis.

AIM: To study effect of extract of ginkgo biloba(EGb) on the lipid metabolism and the function of macrophages from diabetic rats.METHODS: Sprague-Dauley rats were divided into four groups: normal control group,high-fat group,diabetic group and EGb treatment group.At the end of experiment,the rats were sacrificed,the blood glucose,blood insulin and serum lipid were measured.The activity of superoxide dismutase(SOD),content of malondialdehyde(MDA),nitric oxide(NO) in alveolar macrophages(AM) and peritoneal macrophages(PM) were assayed.In addition,peroxisome proliferator activated receptor ?(PPAR?),CD36 mRNA expression in AM was measured by RT-PCR.RESULTS: The concentration of the blood glucose,blood insulin and total cholesterol(TC),total triglycerides(TG),low-density lipoprotein-cholesterol(LDL-C) in blood increased significantly in type 2 diabetic group.The supplement of EGb decreased blood glucose,blood insulin and TC,TG,LDL-C levels.The activity of SOD decreased,while the content of NO,MDA increased in the diabetic macrophages,the activity of SOD became increased,but the content of NO and MDA decreased in EGb-treated group.The mRNA expression level of CD36 and PPAR? in alveolar macrophages from diabetic group increased,while expression level of CD36 and PPAR? mRNA in EGb treated rats continued to rise.CONCLUSIONS: EGb corrected insulin resistance and ameliorated disturbance of lipid metabolism caused by type2 diabetes in rats.Adjustment of PPAR? and CD36 mRNA expression of as well as reduction of lipid peroxidation and NO level may be involved in this process.

Objective To study the correlation between non-alcoholic fatty liver disease (NAFLD)and glycosylated hemoglobin (HbA1 c) in middle-aged and aged population.Methods A total of 4 127 inservice workers and retirees aged 45 years old or above from one petrochemical enterprise in Ningbo were enrolled in our study.The waistline,body mass index,blood pressure,fasting blood-glucose,blood lipid profile,glutamyltranspeptidase,HbA1c and epigastrium B ultrasound were investigated.According to the quartile of HbA1c level,participants were divided into four groups,namely,Q1 group ≤5.2％,Q2 group ＞ 5.2％-5.4％,Q3 ＞ 5.4％-5.6％ and Q4 group ＞ 5.6％.The prevalence of NAFLD and clinical characteristics of each group were analyzed.Logistic regression was used to predict independent risk factors of NAFLD.Results The morbidity of NAFLD was 27.2％ with 31.9％ in male and 21％ in female,which was significantly higher in men.In Q1,Q2,Q3 and Q4 group,the prevalence of NAFLD were 18.5％ (178/961),22.8％ (185/812),25.6％ (280/1 095),38.1％ (480/1 259) respectively.With the increase of HbA1 c level,the morbidity of NAFLD increased synchronously.The age,systolic pressure,total cholesterol,low densitylipoprotein cholesterin and fasting blood-glucose were all elevated according to the increase of HbA1 c in 1 123 NAFLD patients.Multi-factor logistic regression analysis indicated that high HbAlc level was the risk factor of NAFLD (OR =1.67,95％ CI 1.15-2.43,P =0.007).Conclusion HbA1c is an independent risk factor of NAFLD and both of these are closely related to blood lipid metabolism disorder.

Objective To study the regiments of continuous subcutaneous insulin infusion (CSII) in admitted type 2 diabetic patients, and to analyse the factors related to its effectiveness and insulin dosage. Methods A total of 1 276 type 2 diabetic patients were treated by CSII. The total efficacy of CSII was evaluted. The use of CSII was also analysed in the newly diagnosed patients, elderly patients, and patients with obese or infectious disease. Results The excellent control of blood glucose were achieved in (5.7±2.6)days in the dosage more early and quickly in the newly diagnosed group than that in the previously diagnosed group after the blood glucose levels achieved good control. The percentage of the patients reached the clinical relieve was also higher in the newly diagnosed group. The incidence of hypoglycemia was significantly higher in the elderly patients with lower basal insulin dosage at night. The bolus insulin dosage in the obese patients was higher than that in the non-obese patients. The patients with infectious disease usually have a higher basal insulin dosage than those without infectious disease. The days needed for achieving good control of blood glucose and the insulin dosage were related to infectious factors, the basal blood glucose and obesity. Conclusion The application of CSII among the patients is varied with different conditions. Blood glucose level, body mass index and infection factors are important to determine the initial insulin dosage.

Traditional Chinese medicine treatment is the key to restore the balance of Yin and Yang through gasification. So it is important to discuss the mode of gasificaiton of Qi and Chinese medicine and their relationship in the machanism of the Chinese medicine for diseases. Life is a mode of Qi and Qi movement and gasificaiton make people alive. The Chinese medicine works on the Qi gasification to balance the Yin and Yang to keep the peace inner and outsides.

Soil archaea and fungi play important roles in the greenhouse soil ecosystem. To develop and apply rich microbial resources in greenhouse ecological environment, and to understand the interaction between microbes and plants, we constructed archaeal 16S rRNA and fungal 18S rRNA gene libraries to analyze the compositions of archaeal and fungal communities. Total greenhouse soil DNA was directly extracted and purified by skiving-thawing-lysozyme-proteinase K-SDS hot treatment and treatment of cetyltriethylammnonium bromide (CTAB). After PCR amplification, retrieving, ligating, transforming, screening of white clones, archaeal 16S rRNA and fungal 18S rRNA gene libraries were constructed. The sequences of archaea and fungi were defined into operational taxonomic units (OTUs) when 97% similarity threshold for OTU assignment was performed by using the software DOTUR. Phylogenetic analysis showed that crenarchaeota and unidentified-archaea were the two major sub-groups and only a few of euryarchaeota existed in the archaeal clone library, total 45 OTUs. All the crenarchaeota belonged to thermoprotei; except for Basidiomycotina, the other four sub-group fungi were discovered in the fungal library, total 24 OTUs. The diversities of archaea were very abundant and a few euryarchaeota (methanebacteria) existed in the archaeal clone library, it might be directly related to the long-term high temperature, high humidity, and high content of organic matter. The limitation of oxygen was the other reason for causing this phenomenon; Ascomycotina (over 80%) was the dominant sub-groups in fungal library. It was because most of the plant fungal diseases belonged to soil-borne diseases which gone through the winter by the ways of scierotium or perithecium and became the sources of primary infection.

Objective:To summarize the ultrasound manifestations of submucosal cleft palate, and explore the diagnostic value of prenatal ultrasound for submucosal cleft palate.Methods:A total of 21 146 pregnant women who underwent fetal ultrasound examination in the second and third trimesters in the Affiliated Hospital of Jining Medical University from January 2013 to May 2018 were collected. They were all singleton pregnancy. The ultrasound image which was the horizontal plate of the palatine bone at the posterior border of the fetal hard palate was routinely obtained. The presence of bone loss at the posterior border of the hard palate was defined as a positive case. Then the palate targeted ultrasound examinations of the positive cases were performed to observe the continuity of the soft palate. The ultrasound images of positive cases were compared with the results of induction or delivery, and their postpartum diagnosis and treatment were tracked.Results:A total of 44 simple cleft palate were detected in 21 146 fetuses, including 23 dominant cleft palate and 21 submucosal cleft palate. Two cases of 21 submucosal cleft palate were induced because of other deformities, the other 19 cases were born. The follow-up of the 19 submucosal cleft palate cases showed that 15 cases visited to stomatology department before 3 years of age, and 2 cases of newborns with dominant cleft palate were misdiagnosed as submucosal cleft palate by prenatal ultrasound, and the other13 of them were clinically diagnosed as submucosal cleft palate. The ultrasound of the submucosal cleft palate showed there was no inverted "V" -shaped bone in the posterior edge of the hard palate which was connected by a membranous connection, and the soft palate was complete, but the center of soft palate was thinner or even present membranous hyperechoic in ultrasound.Conclusions:Submucosal cleft palate has characteristic ultrasound features, and prenatal ultrasound make a diagnosis and provide some basis for obtaining early diagnosis and treatment after birth.
