Cancer Research and Clinic 2015;27(1):64-66
Selective killing effect of Newcastle disease virus (NDV) on tumor cell makes it a potential anti-cancer agent that is widely studied.In recent years,NDV has become a research hotspot in anti-tumor medicine,while the ability to specifically kill tumor cells is the basis of antitumor drug.The tumor-specific killing characteristics and related mechanisms of NDV are reviewed.
2. Research progress in influence factors of excretion delay of high-dose methotrexate
Chinese Pharmaceutical Journal 2013;48(22):1892-1896
OBJECTIVE: In order to make a more rational clinical use of methotrexate and reduce adverse reactions, we summarize the factors that might cause excretion delay of high-dose methotrexate. METHODS: After consulting relevant domestic and overseas documents published recently, we summed up some factors that might cause excretion delay of high-dose methotrexate. RESULTS AND CONCLUSION: Physiological states of patients, drug interactions, drug-metabolizing enzymes, and many other factors all may lead to excretion delay of methotrexate. Therefore, we should pay attention to these factors to reduce the incidence of excretion delay and ensure safe medication in clinical application of methotrexate.

Objective To investigate the in-hospital death-related factors for acute encephalocele in patients with craniocerebral injury for craniotomy in order to provide evidence for clinical treatment and prognosis determina-tion.Methods The clinical data of 105 patients with craniocerebral injury occurring acute encephalocele during cra-niotomy were analyzed retrospectively.The correlations of the factors including sex,age,preoperative Glasgow coma scale(GCS)scores,preoperative intracranial pressure(ICP),postoperative pupil status,causes of encephalocel,post-operative GCS scores,postoperative ICP,coagulation mechanism,brain swelling,preoperative hypoxia,preoperative blood pressure and blood glucose were analyzed.Results The prognosis was assessed according to the Glasgow out-come scale(GOS)scores after procedure.There were 77 patients in death group(namely death cases)and 28 patients in survival group.Logistic regression analysis showed that postoperative GCS scores (Wald =14.127,Exp(B)=0.044,95%CI:0.032,0.448),causes of encephalocel(Wald =7.748,Exp(B)=8.183,95%CI:1.825,10.251), postoperative ICP(Wald =7.637,Exp(B)=7.637,95% CI:1.969,8.028),postoperative pupil status(Wald =4.001,Exp(B)=2.499,95%CI:1.019,5.122)and blood glucose(Wald =7.915,Exp(B)=8.891,95% CI:1.790,9.337)were closely associated with the in-hospital death in patients with acute encephalocele in craniocere-bral injury operation(P <0.05).Conclusion The postoperative GCS scores,causes of encephalocel,postoperative ICP,postoperative pupil status and blood glucose could be used as the important indexes for predicting in-hospital death of acute encephalocele in craniocerebral injury for craniotomy.To prevent the intraoperative encephalocele and reduce the intracranial pressure are the important measures to reduce the mortality rate of the patients with acute encephalocele.

Objective To understand the house-dust mite fauna in the school dormitory in Guangzhou city.Methods With the direct smear method and saturation solution of NaCl floatation method,a total of 970 bed-dust samples collected from the five school dormitory buildings were examined,from Oct.to Dec.in 2006.The house-dust mite in the samples were counted and classified.Results The prevalence rate of mite was 98.76%.About 72% of the samples,the number of mites was 500 and 3 000/g dust.Mean number of the mites in bed-dust samples showed a significant difference between the male and female student dormitory,and among five dormitory buildings.The mean number of mites usually decreased as the floor increased.Dermatophagoides pteronyssinus,Dermatophagoides farinae,gamasid mites,scab mites and pyemotidae etc were found in the samples.Conclusion House-dust mites universally exist in bed-dust of the school dormitory in Guangzhou city and the number is larger.Dermatophagoides pteronyssinus,Dermatophagoides farinae are the dominant kinds among the mites.

Objective To study the outcome of ureterocele trated by open surgery and by endoscopic manipulation. Methods We reviewed 29 cases of ureteroceles, including 16 intravesical ureteroceles and 13 extravesical ureteroceles. 19 cases were treated by open surgery and 10 by endoscopic procedure. Results 11 cases of intravesical ureteroceles and 8 cases of extravesical ureteroceles under went open surgery, The reoperation rate was 18.1% and 12.5%, respectively. 5 cases of intravesical ureteroceles and 5 cases of extravesical ureteroceles underwent endoscopic treatment,the reoperation rate being 40.0% and 80.0% respectively. Conclusions Endoscopic approach might be the primary management for intravesical ureteroceles, but open surgery is a favorable alternative for extravesical ureteroceles.

OBJECTIVE:To determine the concentration of clindamycin in woman milk by RP-HPLC.METHODS:The concentration of clindamycin(with tinidazole served as internal standard) was determined by liquid-liquid extraction-HPLC.The chromatographic column was Luna C18 and the mobile phase consisted of acetonitrile-tetrahydrofuran-phosphate buffer (pH 5)(30∶1∶70) at a flow rate of 0.8 mL?min-1.The temperature of the column was kept at 40 ℃ and the detection wavelength was set at 205 nm.RESULTS:The linear range of clindamycin was 0.529~10.580 ?g?mL-1(r=0.996 7) with a lowest detectable limit of 0.2 ?g?mL-1.The average methodological recovery rate of clindamycin was 98.84%;both the inter-day RSD and intra-day RSD of clindamycin(at low,medium and high concentrations) were all less than 5%.CONCLUSION:The method is simple,rapid,sensitive,accurate and reproducible,and it is applicable for the determination of clindamycin concentration in woman milk.
9.Influencing factors for lean non-alcoholic fatty liver disease
Journal of Preventive Medicine 2024;36(11):953-957
Abstract:
To investigate the factors affecting lean non-alcoholic fatty liver disease (NAFLD), so as to provide the reference for the prevention and treatment of lean NAFLD.
Methods:
Individuals who underwent physical examination at Huzhou Central Hospital from January 1, 2023 to March 31, 2024 and had a body mass index (BMI) <23 kg/m2 was selected. Demographic information, lifestyle behaviors, dietary habits and physical examination data were collected through questionnaire surveys. Lean NAFLD was assessed using abdominal ultrasonography combined with BMI. Factors affecting lean NAFLD were analyzed by using a multivariable logistic regression model.
Results:
A total of 627 individuals were surveyed, with a mean BMI of (20.83±2.01) kg/m2. There were 349 males (55.66%) and 278 females (44.34%). Lean NAFLD was detected in 74 cases, with a detection rate of 11.80%. Multivariable logistic regression analysis identified BMI (OR=1.830, 95%CI: 1.165-2.869), gender (male, OR=2.615, 95%CI: 1.402-4.875), triglycerides (OR=3.062, 95%CI: 1.613-5.812), alanine aminotransferase (OR=1.587, 95%CI: 1.106-2.277), vegetable and fruit intake (150-300 g/d, OR=0.416, 95%CI: 0.230-0.752; >300 g/d, OR=0.303, 95%CI: 0.141-0.649), dairy product intake (≥300 mL/d, OR=0.369, 95%CI: 0.195-0.701) and sugared beverage intake (1-250 mL/d, OR=1.601, 95%CI: 1.071-2.393; >250 mL/d, OR=2.438, 95%CI: 1.363-4.354) as factors affecting lean NAFLD.
Conclusion
The risk of lean NAFLD is associated with BMI, gender, triglyceride, alanine aminotransferase, and the vegetable and fruit, dairy product and sugared beverage intake.

Objective To investigate the variation in the position of conus medullaris in Chinese adult population in order to avoid hitting conus during spinal puncture. Methods Eight hundred patients suffering from back pain, aged 18-91 yr, were enrolled in this study. The position of conus medullaris was determined using Siemens 1.5 T magnetic resonance imaging system. According to the method described by Reimann, the vertebral body was used as mark of reference to the level of the end of conus. Results There were 190 patients in whom the position of the end of conus medullaris was lower than L1,2 . The incidence of the position of the end of conus medullaris lower than L1,2 was higher in patients 30-60 or older than in those under 30, and in those over the age of 60 than in those 30-60 (P < 0.05). Conclusion Spinal puncture should be performed cautiously at L2,3. CT or MRI is recommended before operation for the patients to locate the position of conus medullaris and avoid injury to the spinal cord.
