Objective To investigate the mechanism of treatment of lung cancer with Bacillus Calmette-Guerin Polysaccharides nucleic acid (BCG-PSN) combined with Cyclophosphamide(Cy). Methods 130 mice were divided into three groups (A,B and C groups). Gruop A was further divided into four subgroups . Subgroup A-1 was given normal saline orally 0.25mg/10g?d -1 ; Subgroup A-2 was given levomisole PO. 0.25mg/10g?d -1 ; Subgroup A-3 was given BCG-PSN PO.0.325mg/10g?d -1 and subgroup A-4 was given BCG-PSN by intra-abdominal injection 0.25mg/10g?d -1 . Group B was given identical drugs with group A, after fifth day given 20% sheep red blood cell 0.2ml by intra-abdominal injection for five days . Gruop C divided into five subgroups;Subgroup C1-4 were given same drugs with group A,then given 0.4% Cy by subcutaneous injection 0.25mg/10g?d -1 from fifth day to tenth day.Subgroup C-5 was normal contral group, was given normal saline 0.25mg/10g?d -1 PO and subcutaneous injection 0.25mg/10g?d -1 .Results Oral administration alone or intra-abdominal injection in subgroup A-4 obviously enhanced the phagocytosis of macrophages.The subcutaneous injection of Cy could obviously decrease anti-tumour immunity, including activity of interleukin-2 (IL-2),natural killer(NK) cell, lyphocyte trasformation, and macrophages phagocytosis. BCG-PSN could increase and rehabilitate above anti-tumour immunological function. Conclusions Combinative treatment of BCG-PSN with Cy could remarkable enhance the immunocompetence.This experiment may provide a theoretical evidence for BCG-PSN combined with chemotheapeutic agents applied to treat the lung cancer.

Objective To explore the value of laparoscopic diagnosis and treatment for Meckel’s diverticulum in children. Methods Laparoscopic exploration was performed in 11 children with suspected intestinal Meckel’s diverticulum. In other 2 children, the diverticulum was encountered during laparoscopic appendectomy, and then the umbilical incision was prolonged to take out the corresponding intestine for resection. Results No conversions to laparotomy were required in all the 13 children. The operation time lasted 30~90 min (mean, 75 min). The children were discharged at 5~6 postoperative days without complications. Conclusions Laparoscopic diagnosis and treatment for Meckel’s diverticulum in children is effective.

OBJECTIVE:To establish a method for simultaneous determination of valsartan and hydrochlorothiazide in Valsar-tan hydrochlorothiazide tablets. METHODS:UPLC was adopted. The determination was performed on Phenomenex C18 column with mobile phase consisted of [0.1% phosphoric acid solution-acetonitrile(95 : 5,V/V)]-[0.1% phosphoric acid solution-acetonitrile (5 : 95,V/V)](gradient elution)at the flow rate of 0.25 mL/min. The detection wavelength was set at 272 nm,and the column tem-perature was 35 ℃. The sample size was 1.5 μL. RESULTS:The linear range were 8.1-324.2 μg/mL for valsartan(r=0.9999)and 1.2-50.1 μg/mL for hydrochlorothiazide(r=0.9999). The limits of quantitation were 0.24,0.04 ng,and the limits of detection were 0.06,0.01 ng.

Objective:To investigate the risk factors and predictive effect of lateral cervical lymph node metastasis of papillary thyroid carcinoma (PTC) by applying the concept of central lymph node metastasis intensity.Methods:This study retrospectively analyzed integrated clinic data of 106 cases with PTC undergoing treatment of cervical lymph node dissection in Department of Thyroid and Breast Surgery of the Affiliated Hospital of Inner Mongolia Medical University from Dec. 2009 to Jan. 2014. Based on whether lateral cervical lymph nodes had metastasis, patents were classified into lymph node metastasis positive group ( n=75 cases) , lymph node metastasis negative group ( n=31 cases) . This study explored metastasis-associated risk factors of age, gender, triiodothyronine (T3) , thyroxine (T4) , free triiodothyronine (FT3) , free thyroxine (FT4) , thyroid stimulating hormone (TSH) , thyroglobulin antibody (TGAb) , thyroid peroxidase antibody (TPOAb) , whether combined with Hashimoto’s disease, tumor location, infringing the membrane, mulifocality, tumor glands distribution, tumor diameter, number of central lymph node metastases, central lymph node metastasis ratio, and analyzed the effects of central lymph node metastasis intensity on lateral cervical lymph node metastasis. SPSS 21.0 software was used for data analysis, the metering data of normal distribution was expressed as ± s, and t test was used for comparison between groups. Count data was expressed as a rate (composition ratio) , and comparisons between groups were performed by χ2 test or Fisher exact probability method. Results:Univariate analysis found that whether combined with Hashimoto’s disease ( P=0.087) , tumor location ( P=0.249) , tumor glands distribution ( P=0.219) and tumor diameter ( P=0.224) had no correlation with lateral cervical lymph node metastasis, which showed no statistical significant differences ( P>0.05) . Infringing the membrane ( P=0.030) , mulifocality ( P=0.031) , number of central lymph node metastases ( P=0.022) and central lymph node metastasis ratio ( P=0.001) had correlation with lateral cervical lymph node metastasis, which showed statistical significant differences ( P<0.05) . The number of central lymph node metastases and the increase of central lymph node metastasis ratio had positive correlation with the occurrence of lateral cervical lymph node metastasis; when the number of central lymph node metastases was ≥4 or (and) the central lymph node metastasis ratio was ≥20%, the incidence of lateral cervical lymph node metastases increased significantly, and the difference was statistically significant ( P<0.05) . Conclusion:Infringing the membrane and mulifocality are risk factors for lateral cervical lymph node metastasis. When central lymph node metastasis intensity: number of metastases ≥4 or (and) metastasis ratio ≥20%, lateral cervical lymph node dissection is recommended.

?AlM: To investigate theprotective effect of melatonin against hydrogen peroxide ( H2 O2 )-induced oxidative damage to human lens epithelial cells.
?METHODS: Sub-culture human lens epithelial cells preprocessed with different concentrations of melatonin for 12h and then 100 μmol/L H2 O2 for 24h. The impact of melatonin on H2 O2-induced lens epithelial cell viability was detected by MTT assay, rate of apoptosis was detected by flow cytometry instrument and activity of apoptosis-related factors, Caspase-3 and Caspase-9, were detected by colorimetric method.
?RESULTS: MTT assay showed that melatonin had no effect on the activity of lens epithelial cells, and the drug can inhibit the decrease of H2 O2-induced cell activity, as well as flow cytometry showed that melatonin can inhibit H2 O2-induced apoptosis. ln addition, melatonin can also reduce H2 O2-induced Caspase-3 and Caspase-9 activity in lens epithelial cells, and their activity decreased with effect of melatonin along with extending time.
?CONCLUSlON: Melatonin can obviously inhibit H2 O2 -induced apoptosis of human lens epithelial cells, which provide reliable experimental basis for drug on treatment of cataract.
