Objective:To improve the quality standard for Shengji ointment. Methods:A TLC method was used to identify Resina draconis and Olibanum. An HPLC method was used to determine the content of silver sulfadiazine. The detection wavelength was set at 254 nm. The determination was performed on a Wondasil C18 column(250 mm × 4. 6 mm, 5 μm) with the mobile phase consisting of acetonitrile-0. 1% phosphoric acid(8: 92). The injection volume was 5 μl. Results:The TLC spots were clear, specific and repro-ducible. A good linear relationship was obtained between the peak areas and the concentrations of sulfadiazine within the range of 40. 97-1024. 18 μg·ml-1(r=0. 9999). The average recovery was 100. 17% (RSD=0. 64%,n=6). Conclusion: The methods are easy-operated, specific, reproducible and accurate, which can be used for the quality control of the preparation.

Objective:To establish a GC method for determining the content of amantadine hydrochloride in pediatric paracetamol and amanatadine hydrochloride granules. Methods:The ingredients were separated on an Agilent DB-5 quartz capillary column (30 m ×0.25 mm, 0.25 μm), the carrier gas was N2,and the flow rate was 1 ml·min-1. The column temperature was maintained at 130℃, the injection temperature was 250℃,the detection temperature was 280℃ with an FID as the detector , the injection volume was 2 μl, and the split ratio was 20∶1. Results:A good linear relationship was obtained between the peak area and the concentration of amantadine hydrochloride within the range from 0.103 2 to 6.456 0 mg·ml-1(r =0.999 9). The average recovery was 100.18%(RSD=0. 11%, n=6). Conclusion:The method is specific, accurate, reliable and reproducible, which can be used in the quality control of pediatric paracetamol and amanatadine hydrochloride granules.

Objective: To examine the association of maternal dietary patterns during pregnancy with the risk of ventricular septal defect (VSD) in offspring. Methods: Seventy-three children with VSD were selected as cases from June 1, 2016 to December 1, 2016; another 73 children without congenital heart or other defects were selected as controls during the corresponding period. VSD was diagnosed by clinical examination and echocardiography figure. Both cases and controls were recruited from Shanghai Children's Medical Center. All the children's mothers were interviewed using a structured questionnaire, which includes information on demographic characteristics and food frequency during pregnancy. Dietary patterns were defined by the factor analysis module of SPSS 23.0. The association between dietary patterns during pregnancy and VSD risk was analyzed by Logistic regression model. Results: Four dietary patterns were obtained by the factor analysis, i.e. vegetable-fruit-high-quality protein pattern, animal food pattern, high sodium and high fat pattern and aquatic product pattern. After adjusting for possible confounding factors, it was demonstrated that the vegetablefruit- high-quality protein pattern and aquatic product pattern were negatively associated with VSD risk in offspring (P<0.05). Conclusion: Maternal dietary patterns during pregnancy that are rich in high-quality protein, vegetables, fruit and aquatic products may be helpful for decreasing VSD risk in offspring.

In this paper,a maxillary molar retractor was introduced.It could control the direction of orthodontic force and provide a quick and easy solution for reposition of the tooth and correction of scissors-bite.

Objective To evaluate abdominal imaging in AIDS.Methods The imaging examinations(including US,CT and MR)of 6 patients with AIDS associated abdominal foci were analysed retrospectively.All the cases were performed US,and CT scan,of which 4 performed enhanced CT scan and 1 with MR.Results Abdominal tuberculosis were found in 4 patients,including abdominal lymph nodes tuberculosis(3 cases)and pancreatic tuberculosis(1 case).The imaging of lymph nodes tuberculosis typically showed enlarged peripheral rim enhancement with central low-attenuation on contrast-enhanced CT. Pancreatic tuberculosis demonstrated low-attenuation area in pancreatic head and slightly peripheral enhancement.Disseminated Kaposi's sarcoma was seen in 1 case:CT and MRI scan demonstrated tumour infiltrated along hepatic portal vein and bronchovascular bundles.Pelvic tumor was observed in 1 case:CT scan showed large mass with thick and irregular wall and central low attenuation liquefacient necrotic area in the pelvic cavity.Conclusion The imaging findings of AIDS with abdominal foci is extraordinarily helpful to the diagnosis of such disease.Tissue biopsy is needed to confirm the diagnosis.

Objective To investigate early Epstein-Barr virus (EBV) reactivation and the outcome of preemptive therapy after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods From January 2007 to January 2009, totally 277 patients after allo-HSCT were studied (haploidentical 116,unrelated 75, matched sibling 86). Conditioning regimens were mainly busulfan (BU) + cyclophosphamide ( CY)/fludarabine(Flu) or total body irradiation (TBI) + CY/Flu. Antihuman thymocyte globulin (ATG)was added in haploidentical and unrelated transplants. Plasma EBV DNA was monitored once to twice weekly in the first 3 months after allo-HSCT with real time quantitative polymerase chain reaction (RQ-PCR). EBV viremia was diagnosed when EBV DNA was more than 5 × 102 copies/ml but without symptoms. Acyclovir (10 mg/kg, intravenous drip, 8 h) was used for preemptive therapy and immnuo-suppressants were decreased if possible. Results Totally 33 patients ( 11.9% ) developed EBV viremia with a median time at day 44 (day 19 to day 84). The incidences of EBV viremia in the transplants from matched sibling,haploidentical, unrelated donors were 0, 15.5%, 20. 0%, respectively. There was no significant difference between haploidentical and unrelated transplants ( P = 0. 09 ), but much less EBV viremia was seen in matched sibling transplant ( P = 0. 001 ). Twenty of 33 patients ( 60. 6% ) had complete response to preemptive therapy. The median time to reach EBV DNA negative in plasma was 11 (4-56) d. The median duration of preemptive therapy was 21 (14-60) d. Both univariate and multivariate analysis indicated that haploidentical and unrelated transplants, acute graft versus host disease (GVHD) were the risk factors for EBV viremia. Two-year overall survival in the patients with EBV viremia was significantly lower than that without EBV viremia (54. 2% vs 72. 1%, P = 0. 006 ). Conclusions Our large clinical study has demonstrated that preemptive therapy with acyclovir that is guided by EBV viremia is effective in majority of the patients with high-risk for EBV reactivation after allo-HSCT, which may further decrease the risk for developing life-threatening EBV disease or post-transplantation lymphoproliferative disorder. Haploidentical and unrelated transplants, acute GVHD are the risk factors for EBV viremia which has negative impact on survival.

To evaluate whether prostate volume (PV) would provide additional predictive utility to the prostate health index (phi) for predicting prostate cancer (PCa) or clinically significant prostate cancer, we designed a prospective, observational multicenter study in two prostate biopsy cohorts. Cohort 1 included 595 patients from three medical centers from 2012 to 2013, and Cohort 2 included 1025 patients from four medical centers from 2013 to 2014. Area under the receiver operating characteristic curves (AUC) and logistic regression models were used to evaluate the predictive performance of PV-based derivatives and models. Linear regression analysis showed that both total prostate-specific antigen (tPSA) and free PSA (fPSA) were significantly correlated with PV (all P < 0.05). [-2]proPSA (p2PSA) was significantly correlated with PV in Cohort 2 (P< 0.001) but not in Cohort 1 (P= 0.309), while no significant association was observed between phi and PV. When combining phi with PV, phi density (PHID) and another phi derivative (PHIV, calculated as phi/PV0.5) did not outperform phi for predicting PCa or clinically significant PCa in either Cohort 1 or Cohort 2. Logistic regression analysis also showed that phi and PV were independent predictors for both PCa and clinically significant PCa (all P < 0.05); however, PV did not provide additional predictive value to phi when combining these derivatives in a regression model (all models vs phi were not statistically significant, all P > 0.05). In conclusion, PV-based derivatives (both PHIV and PHID) and models incorporating PV did not improve the predictive abilities of phi for either PCa or clinically significant PCa.
