Objective To analyze the clinical effect of comprehensive intervention on bone loss in postmenopausal women, and to provide reference for the prevention of osteoporosis in postmenopausal women .Methods 152 cases of postmenopausal bone mass in our hospital from March 2014 to March 2015 were selected as the research object, all patients were randomly divided into intervention group and control group,76 cases in each group.The control group was treated with HRT hormone replacement therapy and calcium supplement treatment , the intervention group based on the treatment in control group by alendronate treatment,supplemented by health guidance, two patients were treated for 1 years.Comparison of two groups of patients before and after treatment, N (N-MID), osteocalcin, procollagen type I amino terminal peptide (PINP), beta crosslinking degradation products (β-CTX), alkaline phosphatase (ALP), bone mineral density L2-L4 (BMD), E2, Serum Osteocalcin (sOC) and calcitonin (CT), parathyroid hormone (PTH), the incidence rate of fracture, osteoporosis, adverse drug reaction.Results There were no significant differences in BMD (L2-L4),β-CTX, N-MID, PINP, ALP and sOC between the two groups; After one year of treatment, BMD and sOC of the two groups were significantly higher than those before treatment (P<0.05), and the levels of β-CTX, N-MID, PINP and ALP were significantly decreased (P<0.05), and the difference between the two groups was statistically significant (P<0.05).There was no significant difference in E2, PTH and CT between the two groups before treatment.After one year of treatment, the above indexes of the two groups were significantly higher than those before treatment (P<0.05), and there was no statistically significant difference between the two groups.In the comprehensive intervention group, one patient ( 1.32%) was diagnosed as osteoporosis and two cases (2.63%) fractured after one year of treatment,In the control group, 11 cases (14.47%) were osteoporosis, 9 cases%). The fracture rate and osteoporosis rate in the intervention group were significantly lower than those in the control group (P<0.05).In the course of treatment,six patients in the comprehensive intervention group had adverse drug reactions, and the alendronate dosage decreased by half,and no adverse drug reaction was found in the control group.Conclusion hormone,Caltrate,alendronate and health guidance comprehensive intervention program to improve the hormone level in patients with osteopenia, bone reconstruction of women physical level and promote the bone tissue of patients with anti absorption to enhance the role of postmenopausal bone balance favorable development, for postmenopausal bone loss in women with a high clinical value.

Purpose:To investigate the influence of MRI on the Chinese 1992 staging system of nasopharyngeal carcinoma(NPC).Methods:From Oct.1992 to Jan.1996,86 patients with NPC who had MRI and CT prior to radiotherapy were retrospectively analyzed.The total dose to the primary tumor was 60.4～85.0 Gy(median,72.5 Gy).The fractionation schedule used was five daily fractions of 1.8～2.0 Gy per week.The survival rates were estimated by the Kaplan-Meier method.Log-rank was used to identify the prognostic factors.Results:The loco-regional control rate at 5 year was 84.2%,distant metastasis-free survival 80.1%,disease-free survival 73.9% and overall survival 82.7% with a median follow-up interval of 65.5 months(range 2～108 months).According to the Chinese 1992 staging system,there were 25 vs 14(25 by CT and 14 by MRI) patients with T_(1),21 vs 8 with T_(2),31 vs 42 with T_(3) and 9 vs 22 with T_(4) lesions.As a result,42.9%(12/28) of cervical nodal and 28.6%(8/28) of retropharyngeal lymphadenopathy alone should downstage from N_(0) to N_(1).Conclusions:The influence of MRI on the Chinese 1992 staging system was significant and the authors observed a worse distribution of patient numbers as well as poorer separation of survival curves among different stage groups.

Objective To investigate the effects of gemcetabine and LY294002 monotherapy or combination on the proliferation and poptosis of pancreatic cancer cell lines BxPc-3 and MiaPaCa-2.Methods Cell proliferation and poptosis were detected by MTT and Annexin V-FTTC,respectively.Results Both gemcetabine and LY294002 could inhabit the proliferation of the two cell lines.Their inhibitory effects were increased accompanied with increased drug concentrations and the cell survival rates was negatively correlated with logarithmic of the drug concentrations (r＜-0.95,P＜0.01).The inhibitory effects of gemcetabine and LY294002 to the BxPc-3 proliferation were significantly stronger than to the MiaPaCa-2(P＜0.05).For BxPc-3 and MiaPaCa-2,the IC50 of gemcetabine were(10.07±1.83),(36.45±2.71)μmol/L(P＜0.05),and the IC50 of LY294002 were(7.84±1.48),(17.89±1.98)μmol/L(P＜0.05),respectively.Gemcetabine and LY294002 could induce cell apoptosis(P＜0.01).Though both the concurrent or consecutive use of these two drugs could promote cell apoptosis,the effect of the concurrent group was significantly stronger(P＜0.05).The order of these two drugs in the concurrent group had no significant influence on their effects(P＞0.05).Conclusion Both gemcetabine and LY294002 could inhibit the proliferation of pancreatic cancer cell lines.Their concurrent application shows a significant inhibitory effect on the cell apoptosis.

OBJECTIVE To explore disinfection effect of ventilator circuits and monitor the best one from two methods for sampling bacterial culture of pre-and post-mechanical physical disinfection ventilator circuit as well as different culture media.METHODS Pre-and post-disinfection ventilator circuits were sampled and cultured by the direct smudge method and the dilution method respectively which simultaneously the ordinary nutrient agar and the blood cultures used.RESULTS Bacterical positive rate of the direct smudge method was significantly higher than that of the dilution method in pre-and post-disinfection ventilator circuits(P0.05).CONCLUSIONS The direct smudge method is superior to the dilution method in monitoring the disinfection effect of ventilator circuit,it can effectively reduce the false negative rate and make the disinfection effect examination to be more accurate.

Objective To determine the effect of high dose albumin on permeability of blood brain barrier (BBB) in brain of rats after ischemic-reperfusion (IR) in order to explore its possible mechanism.Methods Establishment of brain ischemic reperfusion rat model by using middle cerebral artery occlusion (MCAO).Medicine treatment was given by caudal vein injection after 2 hours of MCAO.Thirty-six healthy male SD rats were then randomly (random number) divided into 6 groups (n =6 in each):6 h and 24 h sham-operation groups (Group Sham:operation without ischemia),6 h and 24 h normal saline groups (Group NS:NS injection 5 ml/kg) and 6 h and 24 h albumin group (Group Alb:25 ％ Alb injection 1.25 g/kg).Six hours and 24 hours after the end of reperfusion,rats were measured by Zea-Longa score (neural function deficit) separately.Serum concentration of S100B was examined by the ELISA kit and Evans blue in brain tissue was detected by spectrophotometer.The level of AQP4 was examined by Western blot and immunohistochemistry.All data were analyzed by one-way analysis of variance (ANOVA),The intergroup comparisons were analyzed by the least-significant-difference (LSD) test by using SPSS version 17.0 software.Differences were considered statistically significant if P ＜ 0.05.Results Zea-Longa score significantly increased in both group NS and group Alb at 6 h and 24 h (P =0.000).However,there was no significant difference in ZEA-LONGA score of 6 h and 24 h between group Alb and group NS (P =1.000).The serum concentration of S100B in group NS 6 h was significantly lower than that in group Alb at 6h (196.67±20.11 vs 160.04±14.00,P=0.000),and at24h (2.45±0.07 vs.2.23±0.07,P=0.000).Furthermore,concentration of Evans blue in brain tissue in group Alb was significantly higher than that in group NS at both 6 h (0.97 ± 0.08 vs.0.74 ± 0.06,P =0.000) and 24 h (2.45 ± 0.07 vs.2.23 ± 0.07,P =0.000).The expression of AQP4 in brain tissue was higher in group Alb than that in group NS at both 6 h (0.72 ±.0.11 vs.0.57 ± 0.06,P ＜ 0.01) and 24 h (0.80 ± 0.03 vs 0.61 ± 0.02,P ＜0.01).Conclusions High dose albumin contribute slightly in improvement of neural deficit in rats after IR.On the contrary,it can also aggravate the IR injury,which increases brain edema then increase the permeability of BBB.The mechanism may be associated with over-expression of AQP4 in brain tissue.

This study was aimed to observe the tongue image characteristics at different renal function stages among 157 chronic kidney disease (CKD) patients. Tongue images of 157 CKD cases and 30 healthy people were recorded with the instrument designed by Shanghai University of Traditional Chinese Medicine. Parameters of the tongue image were compared among different renal function stages. The results showed that compared with the control group, there were obvious decreasing on the R and L indexes in groups of different renal function stages (P < 0.05). Compared with the control group, there were obvious decreasing on the G and B indexes in groups of CKD1, CKD2, CKD3 and CKD4 stages (P < 0.05). Compared to CKD4 stage, there were obvious decreasing on the R, G, B, L indexes from group of CKD1 and CKD2 stage (P< 0.05). Compared with the group of CKD5 stage, there were obvious decreasing in the group of CKD1, CKD2, and CKD3 (P< 0.05). Compared with the control group, the cracking index was obvi-ous increased in 5 stages (P < 0.05). There was obvious difference in the greasy index between the group of CKD5 stage and the control group (P< 0.05). Compared with the control group, there was obvious difference in the peeling index from the group of CKD3, CKD 4, CKD5 stage (P < 0.05).

OBJECTIVE:To analyze the clinical efficacy of edaravone combined with Xingnaojing in the treatment of acute severe head injury.METHODS:72 patients with acute severe brain injury were collected from Nov.2008 to Nov.2009 and randomly divided into 2 groups.Treatment group were treated with edaravone and Xingnaojing and control group received edaravone alone.14 days after treatment,APACHE-Ⅱ and GCS score were collected.The overall efficacies of 2 groups were evaluated three months after suffering from injury.RESULTS:The GCS score of treatment group was increased while APACHE-Ⅱ score was decreased,there was statistical significance in difference between 2 groups(P

Objective To evaluate the clinical characteristics,treatment,outcome and complications of child and adolescent nasopharyngeal carcinoma (NPC). Methods From January 1970 to April 1997, the records of 145 NPC patients younger than 21 years of age were reviewed. The clinical stages according to 92'Chinese NPC Staging System were :stageⅠin 1, Ⅱin 8, Ⅲ in 79 and Ⅳ in 57. All patients were treated with external beam radiotherapy. Before 1988, parallel opposed lateral pre-auricular portals were chiefly used in 75 patients and after 1988, parallel opposed lateral facio-cervical portals were adopted in 70. The radiation dose to the primary tumor ranged 45-80?Gy: 70?Gy in 50 cases and 32 of them also received chemotherapy. Results Distant metastasis developed in 26 cases, while local and/or regional recurrence in 14. The actuarial overall survival rates of 1-, 3-, 5, and 10-years were 96.3%, 79.9%, 76.5% and 69.4%, respectively. Among 45 dead cases, 16 did so of metastasis, 11 of local and/or regional recurrence and 18 of other reasons. Univariate analysis suggested that clinical stage, size and site of involved lymph nodes, skull base involvement were significant prognostic factors of survival, whereas sex、age、dose、therapeutic method and chemotherapy were not. Conclusions 1. Even though the majority of pediatric and adolescent NPC were advanced, it signifies a relatively good survival. 2. As the normal tissue of pediatric and adolescent patients tolerates radiation poorly, prudence should be meticulously practiced in deciding the radiation dose and radiotherapeutic fields.
