Objective To investigate the relationship between serum matrix metalloproteinase(MMP-9) and tumor necrosis factor alpha(TNF-α) with bone turnover markers and bone mineral density(BMD) in the patients with chronic obstructive pulmonary disease(COPD) complicating osteoporosis.Methods Eighty-four cases of stable stage of COPD admitted to our hospital were selected and divided into the osteoporosis group(28 cases),low bone mass group(26 cases) and normal bone mass group(30 cases) according to the BMD detection results.ELISA was adopted to detect the MMP-9,TNF-α,bone turnover biochemical markers sBAP,sOC and sCTX levels.Results Serum MMP-9,TNF-α levels in the osteoporosis group and low bone mass group were higher than those in the normal bone mass group,which in the osteoporosis group were higher than those in the low bone mass group,the differences were statistically significant(P<0.05);the sBAP and sOC levels in the osteoporosis group was lower than those in the normal bone mass group,while the sCTX level was higher than that of the normal bone mass group;the sBAP and sOC levels in the low bone mass group were lower than those in the normal bone mass group,the sBAP level in the osteoporosis group was lower than that in the low bone mass group,the sCTX level was higher than that of low bone mass group,the differences were statistically significant(P<0.05);the lumbar vertebral BMD and its T value,femoral neck BMD and its T value in the osteoporosis group and low bone mass group were lower than those in the normal bone mass group(P<0.05),which in the osteoporosis group were lower than those in the low bone mass group(P<0.05);serum MMP-9 was negatively correlated with bone turnover biochemical markers and BMD level(P<0.05);TNF-α was negatively correlated with bone turnove biochemical markers(P<0.05).Conclusion MMP-9 and TNF-α are highly expressed in the patients with COPD complicating osteoporosis,and negatively correlated with the bone bone turnove biochemical markers,meanwhile have a certain relationship with BMD.

Autophagy is a process of self-phagocytosis of lysosomal degrading substances in cells. Under normal conditions,cells can use autophagy to remove their own garbage to provide energy,while in a state of stress,autophagy can also be activated,resulting in cell damage and death,which can seriously lead to cancer. B-cell lymphoma-2-interacting myosin-like coiled-coil protein(Beclin1) is a central node in the autophagy pathway and interacts with a variety of proteins to regulate the formation and maturation of autophagosomes. Kinase mediates the protein modification of Beclin1 during autophagy,which will affect its activity and interaction with other autophagy-related proteins. Beclin1 is closely related to the occurrence and development of tumors. Therefore,this paper focused on the research progress on the mechanism and protein modification of Beclin1 in autophagy,in view to providing a reference for the research of targeted drugs of tumor autophagy.

Objective To explore the value of Nacotrend and the degree and prognosis of disturbance of consciousness in craniocerebral injured patients. Methods Forty craniocerebral injured patients were observed and Nacotrend index (NI) and Glasgow Coma Scale (GCS) were evaluated 24 h after the operation. After followed up for 3 months, the patients with Glasgow coma scale (GOS) 4-5 scores were enrolled into in good recovery group and the patients with GOS 1-3 scores were enrolled into bad recovery group. The correlation of NI and prognosis was analyzed. Results There were 17 cases in the good recovery group, and 23 cases in the bad recovery group. Pearson correlation coefficient of NI and GCS was 0.721, P<0.01. The level of NI in good recovery group was 64.26±12.73, in bad recovery group was 29.57±8.12, and there was significant difference (P<0.05). Conclusion NI can be used in coma patients for consciousness grading assessment and also can correctly evaluate the prognosis.

Objective:To identify potentially pleiotropic genes for lean body mass ( LBM ) and age at menarche ( AAM).Methods:The discovery sample consisted of 1 692 unrelated female subjects of European ancestry.The replication sample consisted of 801 unrelated female subjects of Han Chinese ancestry.A total of 909,622 single nucleotide polymorphisms (SNPs) were genotyped in both samples with the Affymetrix genome-wide genotyping array SNP 6.0.Bivariate genome-wide association analyses were then performed to the appendicular LBM and AAM.Results: Two SNP rs1860547 and rs11030746 identified by the bivariate GWAS were significant at the genome-wide significance (GWS) level;their P-values were <0.05 after replications.In the upstream of rs1860547, two genes KCNA1 and KCNA5 were found to be important for both LBM and AAM.In the downstream of rs11030746, one gene KCNA4 was found.Univariate GWAS also identified both SNPs to be significant at the GWS level; their P-values were <0.05 after replications.In the upstream of rs1860547 , two genes KCNA1 and KCNA5 are found to be important for LBM.In the downstream of rs11030746 , one gene KCNA4 was found.Conclusion:KCNA1, KCNA4 and KCNA5 are likely to be pleiotropic genes closely related to both LBM and AAM in European females.

Objective To investigate the effect of two kinds of permeation enhancers,azone and clove bud oil,on transdermal permeation of Shuxiong cataplasm. Methods Cataplasm containing azone and clove bud oil,at different concentrations were prepared,with ferulic acid as the index,the role of enhancing permeation of azone and clove bud oil for the main active component were studied by in vitro permeation experiments. Results Both azone and clove bud oil at different concentrations could increase permeation. Clove bud oil was better than azone and the best concentration of Clove bud oil is 3%. Meanwhile,the permeation enhancing multiple of clove bud oil group was the highest which was 3.68. Conclusion With the cumulative permeation quantity of ferulic acid as the index,3% clove bud oil is more suitable to act as a permeation enhancer of Shuxiong cataplasm.

Objective To summarize the experience in diagnosis and treatment of ectopic ureter in children. Methods A total of 22 cases (21 females and 1 male;mean age of 4 years,range from 1 month to 12 years) of ectopic ureter were analyzed retrospectively.Of them,17 cases had unilateral ectopic ureters and 5,bilateral.Normal,divided urination accompanied by abnormal leakage of urine occurred in 18 cases;completely continous leakage of urine in 3;and obstruction of upper urinary tract with infection of urinary system in 1.Fourteen cases had opening of ectopic ureters in vaginas,4 in urethras,3 in vestibula and 1 in bladder necks. Results Of the 22 cases 20 underwent surgical procedures.Of the 20 cases,11 had total nephrectomy and 7,partial nephrectomy.After the operation,leakage of urine disappeared,but 3 cases had syndrome of ureteral stump remnant.One case who underwent bilateral ureter-bladder reimplantation had mild urinary incontinence after the operation.One case who had vesica replaced with rectum was followed up for 5 years,the post-operative result was excellent. Conclusions It is of critical importance to establish definite diagnosis and to select appropriate mode of operation for the successful treatment of ectopic ureter in children.

Objective To analyze the cognition, utilization and satisfaction on pregnancy health management of basic public health services. and to find out potential problems and provide suggestions for promoting equality in rural basic public health. The Weishan Lake area was selected as the sample point and the left behind pregnant women in the countryside as control. Methods In the period from May 2016 to July, questionnaires were designed for the pregnancy health management of basic public health services, 330 left-behind pregnant women and 300 rural immigrating pregnant women were selected as our target interviewees. The average age of rural immigrating pregnant women and the left-behind pregnant women was (28.6 ± 3.7) years, and (28.3 ± 3.4) years old, respectively; the degree of education of rural immigrating pregnant women and the left-behind pregnant women was secondary specialized school or high school and junior middle school, respectively. The occupation of rural immigrating pregnant women was mainly workers;accounting for 31.4%, while the occupation of the left-behind pregnant women was farming, accounting for 36.7%. Results The awareness rate ofgeneral pregnancy examination and gynecological examinationin health management items of rural immigrating pregnant women and left-behind pregnant women was the highest, which were 77.7% and 78.3%, respectively, and the lowest awareness rate of the 2 prenatal follow-up was the lowest in the third trimester, which was 22.6% and 23.0%, respectively. The difference was not statistically significant. The maternal health management service understanding rate of rural immigrating pregnant women and left-behind pregnant women were 24.7% and 17.9% respectively , the difference was statistically significant (Z=-1.993, P=0.046);the awareness rate of delivery and breastfeeding in late pregnancy were 36.2% and 47.6% respectively, and the difference was statistically significant (χ2=7.933, P=0.005). The rate of the registering of the maternal health care handbook of rural immigrating pregnant women and left-behind pregnant women were 40.4%and 54%respectively, and the difference was statistically significant (χ2=11.065, P=0.001), Among them, the rate of registering in township hospitals was 46.6% and 73.3% respectively, and the difference was statistically significant (χ2=21.104, P=0.0000); the utilization rate of 3 or more antepartum examination and follow-up services was 8.4%and 23%respectively, and the difference was statistically significant (χ2=23.878, P=0.000). The growth and development of the health of pregnant women and fetal assessment and utilization rates were 9.8% and 23.6%, the difference was statistically significant (χ2=20.460, P=0.000); prenatal guidance (childbirth preparation, breastfeeding) utilization rate were 8%, 13.7%, the difference was statistically significant (χ2=5.011, P=0.027);abnormal or critical maternal referral utilization rate were 22%and 34.8%, the difference was statistically significant (χ2=12.133, P=0.001). Conclusion Imbalance exists in acquiring basic public health services of the two pregnant women cohort, the left-behind pregnant women are better than the rural immigrating pregnant women. Therefore, the government should propagate this service by multi-channel to improve their cognition and utilization of this policy implemented, and to promote the development of the services.

0.05).The results of Western blotting and immunohistochemical method showed that HO-1 protein expression increased in DOX group and DOX-IR group,and was negative in normal group.More distruction of ultrastructural changes of hepatic cells in IR group was found than in DOX-IR group by transmission electron microscope.Conclusion Doxorubicin pretreatment could protect the liver from ischemia-reperfusion injury,which may be related to HO-1 expression induced by doxorubicin,low dosage of doxorubicin does little harm to rat liver.

Medial pancreatectomy has been gradually used in the treatment of benign tumors in neck and body of pancreas since less removal of the pancreas and the retainment of the duodenum,spleen and functional pancreas,it is less harmful to the endocrine and exocrine function of the patients.Seventeen patients received medial pancreatectomy for benign tumors in neck and body of the pancreas in the China-Japan Union Hospital of Jilin University from November 2005 to December 2010.Fifteen patients received the closure of broken ends of pancreatic head,pancreaticojejunostomy,and the other 2 received pancreaticojejunostomy.No perioperative death was found.All the patients were followed up for 2 to 45 months,and no death was recorded.No patient got new-onset diabetes and pancreatic pseudocyst,and their tumors were not relapsed.Now the retrospective analysis was carried out to this group of patients and to further regulate the surgical operation of the medial pancreatectomy.

BACKGROUND: Amnion has been widely used in ophthalmology. Numerous studies have suggested that amnion transplantation did not induce acute immunologic rejection. These indicated that amnion transplantation can be used as a safe material for repair of dural defects.OBJECTIVE: To study the probability of freeze-dried amniotic membrane (FDAM) as a dural substitue. METHODS: Each of the guinea pigs underwent bilateral parietal craniectomy behind the coronal suture and beside the midline to expose the dura. On the right side, a piece of dura mater was removed. The dural defect was covered with a piece of FDAM. The exposed dura on the left was cut and sutured itself as control. The animals in each group were sacrificed at 15, 30, 60 and 90 days after operation, respectively. The implants were harvested and stained with hematoxylin-eosin, and histologically analyzed. RESULTS AND CONCLUSION: After operation, the behavior of all guinea pigs remained completely normal. The wound healing was achieved in all cases. No wound infection, subcutaneous effusion or cerebrospinal fluid (CSF) leakage occurred. The graft was degraded gradually and covered with a sheet of connective tissue. Dural defects repaired with FDAM showed no adhesions to the brain surface. 15 days after operation, plenty of scattered fibroblasts appeared in the dural substitute. 30 days alter dural graft implantation, parts of the implant disappeared; meanwhile the hyperplasia of fibrous connective tissue took place in the center part of the dural substitute, without the infiltration of inflammatory cells. 60 days after implantation, a majority of the dural graft was degraded, substituted by fibrous connective tissue which was of hyperplasia and low-grade degeneration, surrounded by a small quantity of giant cells. 90 days after operation, colloidal degeneration happened in the dural substitute, surrounded by ossification tissue and the degenerated fibrous connective tissue. The inflammatory cells were not discovered. The animal experiment proves FDAM to be a safe and applicable dural substitute.
