1.Comprehensive assessment of BMI cut-off point in metabolic surgery from the view of guideline
Chinese Journal of Diabetes 2015;(9):776-779
Recently ,metabolic surgery has received much concern for its notable and everlasting effectiveness on glucose control ,weight loss and other metabolic disorders and concomitant diseases. Previous clinical practice and guidelines mostly focused on surgical indications ,especially BM I cut‐off point. In recent years ,BMI cut‐off point in guidelines has shown a downtrend and BMI cut‐off value has tended to become obscure ,which harvested from that clinical staff have realized the importance of comprehensive control for long‐term multiple metabolism and risk factors and overall benefit of the patients through increased clinical evidences and no longer limited to the improvement of obesity and diabetes itself.
2.Study progress of breast milk stem cells
Chinese Journal of Applied Clinical Pediatrics 2016;31(14):1113-1115
The immense potency of bioactive molecules of human breast milk and importance of breastfeeding is known worldwide.Less attention has been paid on the cellular constituents and properties of breast milk.In the past decade,a research has been done by multidimensional approach to investigat the cells human milk.Technological advances have played an important role in this work,which has resulted in the breakthrough discovery of breast milk stem cells with self renewal and multilineage potentials.Regenerative medicine may benefit from utilizing these cells.Breast milk stem cells are transferred to the offspring during breastfeeding.This contributes substantially to infant health.This review summarizes the current knowledge on the potential of breast milk stem cells,with emphasis on their origin,properties and future applications.

Cancer Research and Clinic 2017;29(4):235-240
Objective To analyze the expression of programmed death ligand 1 (PD-L1),p16 proteins and DNA topoisomerase Ⅱ α (TOPO Ⅱ α) in cervical cancer and their clinical significances.Methods A total of 181 paraffin-embedded operating specimens and the biopsy including 106 cervical squamous cell carcinoma,30 high grade cervical intraepithelial neoplasia (CIN),30 low grade CIN and 33 normal cervical were selected from January 2014 to December 2015.An immunohistochemical EnVision method was used to detect the expression of PD-L1,p16 and TOPO Ⅱ α.Results The positive rate of PD-L1 expression in cervical squamous cell carcinoma was 66.0 % (70/106),but it was not expressed in high grade CIN,low grade CIN and normal cervical tissues,the differences were statistically significant (all P =0.000).Whereas,in squamous cell carcinoma,the positive rate of PD-L1 in poor differentiation group [77.3 % (51/66)] was higher than that in middle or high differentiation group [56.5 % (21/40)],and the difference was statistically significant (x2 =7.02,P =0.01).According to the FIGO stage,the positive rate in stage Ⅰ-Ⅱ group [54.9 % (28/51)] was lower than that in stage Ⅲ-Ⅳ group [76.4 % (42/55)],and the difference was statistically significant (x2 =5.47,P =0.02).But there was no statistical significance in lesion size or lymph node metastasis (both P > 0.05).The positive rate of p16 in cervical squamous cell carcinoma was 99.1% (105/ 106),in high grade CIN was 86.7 % (26/30),in low grade CIN was 26.7 % (8/30),and no expression in normal cervical tissues,the differences were statistically significant (all P < 0.001).The expression of p16 had no relationship with histological differentiation,FIGO stage,lesion size,and lymph node metastasis (all P > 0.05).The positive expression rate of TOPO Ⅱ α in cervical squamous cell carcinoma was 97.2 % (103/106),compared with that in high grade CIN [73.3 % (22/30)],low grade CIN [66.7 % (20/30)],and normal cervical tissues (no expression),the differences were statistically significant (all P =0.000).But there was nosignificant difference in the positive expression rate of TOPOⅡ α between high grade and low grade CIN (x2 =0.32,P =0.570).The expression of TOPO 1Ⅱ α had no relationship with histological differentiation,FIGO stage,lesion size and lymph node metastasis (all P > 0.05).Conclusion The expression of PD-L1,p16 and TOPO Ⅱ α is associated with the invasion of cervical cancer.PD-L1 may be an immune checkpoint for the treatment of patients with invasive cervical cancer.

Acyl Coenzyme A Oxidase(ACO) is the rate-limiting enzyme of the ?-oxidation of dicarboxylic acid in Candida tropicalis . Using strains with low Acyl Coenzyme A Oxidase activity to produce dicarboxylic acid on an industrial scale will facilitates the improvement of the yield and purity of dicarboxylic acid. In this research, we improved the method of Allain, so as to determine the activity of Acyl Coenzyme A Oxidase from Candida tropicalis easily and correctly. This method can be used as quantity criterion in the screen of industrial strains of dicarboxylic acid production, and this work established the basic of character study of Acyl Coenzyme A Oxidase. We determined the activities of Acyl Coenzyme A Oxidase from a series of Candida tropicalis strains with different ability of dicarboxylic acid production, and found the obvious relationship of ACO activity and ability of acid production.

ObjectiveTo explore the accuracy of judging the T-staging of rectal cancer by biplane transrectal ultrasound.MethodsPathological enteroscopic biopsy was carried out for 197 cases of rectal cancer.Cases of middle and lower rectal cancer without serious obstruction were examined by means of transrectal biplane ultrasound through which to observe the changes of the echoes and to detect the depth of the infiltration in the intestinal walls and the presence of invasions in prostate glands,seminal in male or vesicles,uterine cervix in female.On the basis of the findings,the preoperative tumor staging was made.Postoperatively,the ultrasound results were compared with the pathological examination.Their consistency was evaluated by using Kappa test.ResultsTransrectal biplane ultrasound examination showed the total accuracy rate in T-staging of rectal cancer was as high as 83.8% with the diagnostic sensitivity rate for T1to T4 as 77.8 %,73.1%,89.3% and 94.4%,while its diagnostic specificity rate degree was 97.3%,93.1 %,85.1 %,97.8% respectively,The k -value was 0.732 which suggested that the ultrasound staging was highly consistent with the pathological staging(P<0.05).ConclusionsTransrectal biplane ultrasound has a great value in the preoperative T-staging of rectal cancer and is helpful in the planning of treatment.

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 study the effect of trimetazidine on patients with unstable angina pectoris. Methods The pa-tients with unstable anglna pectoris with routine treatment were divided randomly into trimetazidine group(T) and nitro-glycerin group(N). They were given such treatment two weeks. Results There is decreased incidence of angina pectorisand less amount of nitroglycerin consumption in both groups. compared with before. There was no significant difference be-tween the two groups. Conclusion There are no signficantly. Trimetazidine has a definite effect in treating unstable angi-na pectoris,and it is similar to nitroglycerin in effects.
