OBJECTIVETo observe the effect of Fengshi No. 1 (FS1) in treating patients with active stage of rheumatoid arthritis (RA).

METHODSPatients with RA were randomly divided into two groups, the 40 patients in the treated group were treated with combined therapy of methotrexate (MTX), sulfasalazine (SSZ) and FS1, and the 20 in the control groups were treated with MTX and SSZ alone.

RESULTSIn the treated group, the total effective rate was 97.5%, the clinical controlled and markedly effective rate 95.0% and the occurrence rate of side-toxic reaction 10.0%, as compared with those in the control group, 60.0%, 20.0% and 45.0% respectively, the difference was significant (chi 2 = 11.91, 32.23 and 7.67 respectively, all P < 0.01). The effect in the treated group was superior to that in the control group in abating joint swelling and pain, improving function of joint, reducing immune indices and ameliorating iconographic features (P < 0.01 or P < 0.05).

CONCLUSIONFS1 not only has the effects of anti-inflammation, analgesis, regulating immune reaction, but also could retard the occurring of bone destruction, reduce the toxic-side effects of MTX and SSZ.

Abstract: Objective To analyze the effect of nutrition package on the nutritional status and prevalence of children in rural areas of Hainan Province, and provide scientific basis and suggestions for further improving the nutritional and health status of children in this region. Methods　Four cities and counties were randomly selected as the intervention group, and four cities and counties matched with the intervention group in terms of population, economy, social culture, maternal and child health work foundation of township health centers, physical nutrition and health status were selected as the control group.With the combination of monitoring and prospective cohort study, infants in the intervention group and the control group were studied from June 1, 2020, and they were intervened for 12 months with supplementary food nutrition package. Before and after intervention, the nutrition and health status of infants aged 6-24 months in the intervention group and the control group were investigated to evaluate the nutritional and health effects of supplementary food nutrition package for infants aged 6-24 months in rural Hainan Province. Results　A total of 999 infants were investigated, including 427 in the intervention group and 572 in the control group. After 12 months of nutritional intervention, there was no significant difference in weight-for-age Z-score (WAZ) and height-for-age Z-score (HAZ) and weight-for-height Z-score (WHZ) between the intervention group and the control group (P>0.05). The rate of emaciation of the intervention group was 1.64%, which was significantly lower than 3.67% of the control group (P<0.05). There were no significant differences in the rate of growth retardation (2.81% and 3.32%, respectively) and underweight (0.47% and 1.92%, respectively) between the intervention group and the control group (P>0.05). The rate of respiratory infection and diarrhea in the intervention group were 9.13% and 1.17%, which were significantly lower than corresponding 23.25% and 3.15% in the control group (P<0.05). The hemoglobin of the intervention group and the control group were 117.24 g/L and 114.51 g/L respectively, and the rates of anemia were 11.11% and 22.84% respectively, the differences were statistically significant (P<0.05). Conclusions　The intervention of nutrition package in rural areas of Hainan Province has achieved the expected results, and supplementary food nutrition package has reduced the incidence of malnutrition and respiratory infection and diarrhea in recent two weeks in infants and anemia to a certain extent. We should attach great importance to the supplementary nutrition package for right-age children and promote the growth and health of children in rural areas through supplementary nutrition package, and continuously improve the nutrition and health level of children in Hainan Province.

BACKGROUNDThe prognosis for patients with gastric cancer and synchronous liver metastases is very poor. However, a standard therapeutic strategy has not been well established. The clinical benefit and prognostic factors after hepatic surgical treatment for liver metastases from gastric cancer remain controversial.

METHODSRecords of 105 patients who underwent gastrectomy regardless of hepatic surgical treatment for gastric cancer with synchronous liver-only metastases in our center between 1995 and 2010 were retrospectively reviewed.

RESULTSThe overall survival rate for the 105 patients was 42.1%, 17.2%, and 10.6% at 1, 2, and 3 years, respectively, with a median survival time of 11 months. Multivariate survival analysis revealed that the extent of lymphadenectomy (D) (P < 0.001), lymph node metastases (P < 0.001), extent of liver metastases (H) (P = 0.008), and lymphovascular invasion (P = 0.002) were significant independent prognostic factors for survival. Among patients who underwent D2 lymphadenectomy, those who underwent hepatic surgical treatment had a significantly improved survival compared with those who underwent gastrectomy alone (median survival, 24 vs. 12 months; P < 0.001). However, hepatic surgical treatment was not a prognostic factor for patients who underwent D1 lymphadenectomy (median survival, 8 vs. 8 months; P = 0.495). For the 35 patients who underwent gastrectomy plus hepatic surgical treatment, D2 lymphadenectomy (P < 0.001), lymph node metastases (P = 0.015), and extent of liver metastases (H1 vs. H2 and H3) (P = 0.017) were independent significant prognostic factors for survival.

CONCLUSIONSD2 lymphadenectomy plus hepatic surgical treatment may provide hope for long-term survival of judiciously selected patients with hepatic metastases from gastric cancer. Patients with a low degree of lymph node metastases and H1 liver metastases would make the most appropriate candidates. However, if D2 dissection cannot be achieved, hepatic surgical treatment is not recommended.

Objective To analyze the fertility rate and to estimate the future population size of Shaanxi province,based on data from the sixth national population census.Methods Fertility rate curve was used to analyze the fertility model and the abbreviated life table.The actual fertility rate was used as the main way to predict the future population size.General fertility rate was analyzed by factor analysis approach.Results The total fertility rate of Shaanxi province was 1.05 in 2010 while age-specific fertility rate contributed 101.27％ to the general fertility rate.The expected population sizes would be 38 122 474 in 2015,38 432 931 in 2020 and 38 121 904 in 2025 respectively.Conclusion Birthrate would become lower and the population size appearing a negative increase in the year 2020,in Shaanxi province.

OBJECTIVETo investigate the toxicity of cationic liposome Lipofectamine 2000 (Lipo) in human pancreatic cancer Capan-2 cells.

METHODSCapan-2 cells were cultured in the presence of Lipo at toxic concentrations, and the cell growth, apoptosis and cell cycle changes were evaluated by cell counting and flow cytometry.

RESULTSThe concentrations of both Lipo and siRNA affected the transfection efficiency. In a transfection volume of 2 ml, the presence of 5 microl Lipo resulted in slowed growth of Capan-2 cells, which was especially obvious after 3 days (P<0.001). Prolonged culture of the transfected cells caused significant increases in early apoptotic cells (P<0.05) and in the damaged or necrotic cells (P<0.001), and resulted in reduced viable cells (P<0.01); these changes became obvious after a 48-hour culture, which also increased the ratio of G(0)/G(1) phase cells (P<0.05) and decreased those of G(2)/M phase cells (P<0.01), S phase cells (P<0.01), and the late apoptotic cells (P<0.05).

CONCLUSIONToxic concentrations of Lipo can affect the growth, apoptosis and cell cycles of Capan-2 cells in vitro, and this urges careful concentration selection when using Lipo for gene transfer into different cells.

OBJECTIVECastrated rats exhibit significant shrinkage of the ventral prostate and apoptosis of prostatic cells, which can be attributed to the reduced blood supply to the prostate. But what causes the blood decrease in the prostate remains unknown. This study aims to explore the molecular mechanism of the changes in the microcirculation of the ventral prostate of rats following castration.

METHODSWe randomized 24 male adult rats into 6 groups of equal number, and collected their ventral prostates at 0, 1/2, 1, 2, 3 and 7 d, respectively, after castration. Then we observed the changes of the microvessels under the transmission electron microscope, detected the apoptosis of endothelial cells by TUNEL, and determined the expressions of VEGF, endostatin, angiostatin and angiopoietin-2 by Western blot.

RESULTSThe castrated rats showed dramatic changes in the microvessels of the ventral prostate, obvious apoptosis of the endothelial cells, down-regulated expression of VEGF, and up-regulated expressions of endostatin and angiostatin, while angiopoietin-2 remained unchanged.

CONCLUSIONThe decreased level of VEGF and increased levels of endostatin and angiostatin might underlie the mechanism of the changes in the microcirculation of the ventral prostate of rats following castration.

OBJECTIVETo probe into the mechanism of electroacupuncture intervention for lipid metabolism of metabolic syndrome patients.

METHODSEighty cases of metabolic syndrome were randomly divided into an electroacupuncture combined with western medicine group (observation group) and a simple western medicine group (control group), 40 cases in each group. The observation group was treated with electroacupuncture at Back shu points, Zusanli (ST 36),Zhongwan (CV 12),Sanyinjiao (SP 6) etc. as main combined with oral administration of Simvastatin, Glipizide XL, and Felodipine sustained-release tablets for lipid-lowering, glucose-lowering and antihypertensive treatment; the control group was treated with oral administration of western medicine only (the medicine was the same with observation group). The Body Mass Index (BMI) and the blood lipid of the patients were detected respectively before and after treatment.

RESULTSThe BMI, Three Acids Glyceride (TG), Total Cholesterol(TC), Low Density Lipoprotein Cholesterol (LDL-C) and High Density Lipoprotein Cholesterol (HDL-C) were compared respectively before and after treatment, there were significant differences between them in observation group (all P < 0.01); while in control group, there were significant differences of TG,TC,LDL-C and HDL-C before and after treatment (all P < 0.01), and with no significant difference in BMI before and after treatment. There were significant differences of BMI,TG,TC,LDL-C and HDL-C between two groups after treatment (P < 0.01, P < 0.05).

CONCLUSIONThe electroacupuncture has an obvious effect to reduce body mass, and acupuncture combined with medication has a better effect of improving the lipid metabolism than simple medication.

OBJECTIVETo evaluate the diagnostic value and safety of flexible bronchoscopy in congenital great vessel diseases complicated with airway compression.

METHODThe medical records of patients with great vessels abnormalities who were admitted to the neonatal intensive care unit (NICU) from October 2005 to June 2009 were retrospectively reviewed; 34 cases were diagnosed as airway compression by flexible bronchoscopy, 10 cases as vascular ring, 24 cases as aortal arch obstruction. The age of the patients was 6 d - 11 m, body weight 2.2 - 8.7 kg [(4.6 +/- 1.4) kg]. Recorded airway abnormalities detected by bronchoscopy and CT, cardiac vascular defects and airway compression were consistent with the findings on operation. The relation between the airway compression and cardiac vascular abnormalities, treatment of the airway compression and outcome were analysed.

RESULTBronchoscopic assessment was successfully performed in NICU or operating room for all the patients. (1) Initial presentation of the 34 cases were tachypnea, stridor, refractory lung infection and prolonged mechanical ventilation. (2) Extrinsic compression was found in all the 10 cases with vascular ring by bronchoscopy initially which indicated vascular ring, airway compression was mainly of lower part of trachea. Diagnosis of 9 cases was consistent with CT diagnosis and in 1 case the diagnosis was confirmed by surgery; among these cases, 7 had congenital tracheal stenosis. (3) In the 24 cases with aortic obstructive lesion, 5 were detected to have tracheal stenosis by CT before correction of vascular abnormality, among whom one case was indicated to have tracheal stenosis by bronchoscopy, the other 19 cases were found with airway compression by bronchoscopy during or after vascular correction. Among the 24 cases, 21 had left main bronchial stenosis, 2 had congenital tracheal stenosis. Airway compression diagnosed by bronchoscopy agreed with the findings of CT. Two cases developed transient decrease of oxygen saturation, 5 cases developed transient tachycardia.

CONCLUSIONFlexible bronchoscopy plays an important role in assessment of the airway compression complicated with great vessel abnormalities. Bronchoscopy is an accurate, convenient, safe and rapid way for airway assessment, but further examination of the peripheral structure and vascular malformation need combined examination with CT.
