According to the recent years’ review of international and domestic relating journals and collections, the conception, mechanism, and treatment of sympathetic cervical spondylosis are summarized.All authors have agreed that posterior cervical nerve syndrome proposed by Barre-Lieou and addressed in this paper, whose mechanism mainly is cervical vertebral degeneration stimulus, or oppression upon sympathetic nervous fiber, or spasm of vertebral artery, is generally treated by non-operative methods and cautious operative methods.The main cause of sympathetic cervical spondylosis is cervical vertebral instability, which stimulates sympathetic nervous fiber to make vertebral artery to convulse. And its treatment is mainly conservative treatment and supplementary operation. But it is usually subject to reoccurrence. Operative methods include cervical disk excision, cervical inter-body fusion and bone grafting and inner fixation, instable factor elimination. But eligible condition is relatively short.

[Objective]To analyse the operative complications in total hip arthroplasty.[Method]Sixty-two patients (62 hips) undergone total hip arthroplasty from March 1998 to November2009,were grouped according to the different causes of the operative complications.[Result]Based on the analysis of all cases,it was found that the most common causes resulting in the failure of the surgery were surgical technichque and fracture,anesthesia,osteoporosis,diabetes mellitus,and cerebral hemorrhage.Complications in all 5 cases were sudden death in 1,femural fracture in 1,unequal-length lower timbs in 1,and postoperative dislocation in 2.[Conclusion]Total hip arthroplasty has been extensively used as an effective procedure for the reconstruction of hip joint.Long-term excellent clinical results are related to preoperative preparation,patient matched fact,and the experience and surgical technique of the surgeon are also of importance to the final outcome.

Objective To develop the scale to measure online intimate relationship and test its validity and reliability for college students.Methods A total of 1 105 subjects were recruited in this investigation for 6 times.Based on literatures,open-ended questionnaire investigations,semi-structured interview and experts' opinions,item analyses,exploratory factor analyses,validity and reliability analysis were conducted to develop the scale.Results The self-made scale showed a second-order structure,including intimacy,passion and commitment dimension.Confirmatory factor analysis showed that the model had good fit (χ2/df=3.47,GFI=0.92,NFI=0.90,CFI=0.92,TLI=0.90,IFI=0.92,RMSEA=0.08).The 3 dimensions had good internal reliability with Cronbach's α coefficients from 0.73 to 0.89 and retest reliability coefficients from 0.80 to 0.91.In addition,the scale had good external validity and convergent validity.ConclusionThe self-made scale has acceptable reliabilities and validities,which can be used to measure online intimate relationship for college students.

Objective:To explore the relationship among childhood psychological maltreatment,online aggressivebehavior and trait anger in college students.Methods:Totally 442 college students (226males,216 females,aged 16-25 years) were surveyed with the Psychological Maltreatment Scale (PMS),Adolescent Online Aggressive Behavior Scale (AOABS) and Trait Anger Scale (TAS).The bias-corrected percentile bootstrap method was used to analyze the mediating effect of trait anger between childhood psychological maltreatment and online aggressive behavior.Results:The scores of PMS,AOABS and TAS were positively correlated each other(r =0.44,0.37,0.48,Ps ＜0.01).The PMS scores had a significantly direct effect on the AOABS scores,its estimate was 0.27.The PMS scoreshad a significantly indirect effect on the AOABS scores through TAS scores(95％ CI:0.15-0.34).Conclusion:It suggests that the trait anger may be related to childhood psychological maltreatment and online aggressive behavior,and trait anger may play a partial mediating role between childhood psychological maltreatment and online aggressive behaviorin college students.

Objective:To observe modulation of gut functions and intestinal mucosal immune barrier by ShengJiangXieXinTang in rats receiving Irinotecan(CPT-11).Methods:Sprague Dawley male rats(n=18)were randomly assigned to three groups:(1)herb group (using ShengJiangXieXinTang by oral administration once a day from day 1 to day 9 and being injected with 150 mg/kg?d CPT-11 on day 4 and 5 into the tail vein); (2)diarrhea control group: using distilled water instead of ShengJiangXieXinTang,with the same treatment of CPT-11 as the herb group; (3)normal control group: using normal saline instead of CPT-11, distilled water instead of ShengJiangXieXinTang,and with the same treatment of as the CPT-11 herb group.The animals were scored in terms of delayed-onset of diarrhea. Rats were killed on day 10,collecting ileum,cecum and colon for pathological examination.The damages in intestinal mucosa were assessed under light microscope according to the criterion of chiu's score.CD4+,CD8+T-lymphocytes and SIgA were enumerated by immunohistochemical staining and calculated by imaging analyzer.Results:Compared with diarrhea control group,the incidence of diarrhea and the damage in intestinal mucosa of the herb group was milder(P

Objective To investigate the role of cell adhesion molecule L1 like (CALL) in the genesis and development of esophageal squamous cell carcinoma (ESCC).Methods From July 2007 to December 2010,a total of 100 patients with ESCC who received radical resection of esophageal cancer were enrolled.The ESCC tissues and corresponding tumor-adjacent normal tissues were obtained.The expression of CALl was determined by tissue microarray technology and immunohistochemical staining.The CALL over-expressed esophageal cancer cell line was established.The effects of CALL on cell migration and invasion were detected by wound-healing assay and Transwell assay,respectively.The effects of CALL on actin microfilament was analyzed by filamentous actin (F-actin) staining.Chi square test,Fisher's exact test,multivariate analysis and t test were performed for statistical analysis.Results The positive expression rate of CALL in ESCC tissues was 56 ％ (56/100),which was lower than that of tumor-adjacent normal tissues (95％,95/100),and the difference was statistically significant (x2=41.114,P＜0.01).There were statistically significant differences in CALL expression at protein level among patients with ESCC of different differentiation degree,different pathological T stage,lymph node metastasis and different TNM stage (x2=13.702,5.317,21.453,Fisher's exact test;all P＜ 0.05).The five year disease related survival rate of ESCC patients with down-regulated expression of CALL was 0(0/49),which was lower than those with normal CALL expression (25.5％,13/51),and the difference was statistically significant (x2 =43.338,P＜0.01).The median survival time of CALL expression down-regulated group was 17 months,and that of normal expressed group was 38 months.CALL expression was an independent risk factor of disease special survival rate (hazard ratio (HR) 0.353,95％ confidence interval (CI) 0.188 to 0.666,P=0.001).The results of wound-healing assay showed that the migration ability of CALL overexpressed CALL-k30 cells was lower than that of Vec-k30 cells in control group on 24 hours after wound.The results of Transwell invasion test showed the number of migrating cells penetrating CALL k30 cells attached to the inferior surface of the membrane was 44.000±13.748,which was less than that of the Vec k30 cells (154.333±25.007),and the difference was statistically significant (t=5.136,P=0.036).The results of F-actin staining demonstrated that actin filaments of CALL-k30 cells was 234.667 ± 65.118,which was lower than that of Vec-k30 cells (597.000± 119.929),and the difference was statistically significant (t=4.707,P=0.042).Conclusions CALL lowers the migration and invasion abilities of esophageal cancer cells by inhibiting F-actin microfilaments.Its abnormal expression may play an important role in the genesis,development and prognosis of ESCC.

Objective: To observe the clinical efficacy of apatinib combined with chemotherapy for advanced gastric cancer as secondline and above treatment, and to analyze the survival of patients. Methods: Seventy-two patients with advanced gastric cancer that treated at Department of Oncology, the First Affiliated Hospital of Zhengzhou University from March 2016 to April 2017 were included in this study according to the inclusion and exclusion criteria; patients were randomly divided into chemotherapy group, apatinib group, apatinib combined with chemotherapy group. And the clinical efficacy and the survival of patients were investigated. Results: For chemotherapy group, apatinib group, apatinib combined with chemotherapy group, the disease control rate (DCR) and objective response rate (ORR) were 48.3%, 61.1%,72.0% (P>0.05) and 13.8%, 16.7%, 28.0%(P>0.05), respectively; and the incidence rate of adverse reaction at grade three-four was 17.1%, 16.8% and 24.0% (P>0.05), respectively. Compared with the chemotherapy group (93 d), the median progress-free survival (mPFS) time in the apatinib group and apatinib combined with chemotherapy group was 117 d (P=0.128) and 160 d (P=0.001). Furthermore, univariate and multivariate analyses showed that TNM staging (P=0.036), ascites (P=0.041) and treatment regimen (P=0.001) were the independent factors affecting PFS. Conclusion: As the second-line or above treatment in advanced gastric cancer, compared with single chemotherapy and single apatinib group, apatinib combined with chemotherapy displays more satisfactory achievement in remission rate, accompanied by controllable adverse reactions and considerable survival benefit.

Objective:To explore the role and molecular mechanism of hepatocyte nuclear factor 4γ (HNF4γ) in proliferation and stemness of gastric cancer.Methods:A total of 102 cases of paraffin-embedded gastric cancer tissues and matched adjacent gastric tissues and 42 cases of fresh-frozen tissues derived from gastric patients who received radical gastrectomy were collected from the First Affiliated Hospital of Zhengzhou University between 2012 to 2015. The expression of HNF4γ was tested by immunohistochemical staining, quantitative real-time polymerase chain reaction (qRT-PCR). HNF4γ overexpressed (AGS-HNF4γ) and shRNA silenced (HGC27-shHNF4γ) gastric cell lines were established. The effects of HNF4γ on cell proliferation and stemness were verified by XTT, clone formation and sphere formation assay. The expression of CD44 was detected by western blot.Results:The mRNA expression level of HNF4γ in fresh-frozen gastric cancer tissue was (12.43±2.702), which was significantly higher than (3.639±1.109) in normal tissue ( P<0.001). The high protein expression rate of HNF4γ in paraffin-embedded gastric cancer tissues was 41.2% (42/102), which was significantly higher than 8.8% (9/102) in normal gastric mucosa tissue ( P< 0.001). The protein expression of HNF4γ was closely related to the tumor differentiation, infiltration depth, lymph node metastasis and tumor stage ( P<0.05). The median survival interval of patients with HNF4γ high expression was 25 months, the 3-year survival rate was 4.8% (2/42), significantly lower than 38 months and 51.7% (31/60) of patients with normal HNF4γ expression ( P<0.001). The proliferation and CD44 protein expression of AGS-HNF4γ cells were significantly higher than those of the AGS-Vector cells. The number of clone formation, sphere formation rate of AGS-HNF4γ cells were 243.5±24.5 and (83.5±3.9)%, significantly higher than 81.0±16.0 and (21.8±5.6)% of AGS-Vector cells ( P=0.030 and P=0.010, respectively). The proliferation and CD44 protein expression of HGC27-shHNF4 cells were significantly lower than those of the HGC27-vector cells. The number of clone formation, sphere formation rate of HGC27-shHNF4 cells were 26.0±1.0 and (20.8±8.4)%, significantly higher than 83.5±4.5 and (72.5±4.8)% of HGC27-vector cells ( P=0.006 and P=0.030, respectively). Conclusions:HNF4γ is upregulated in the gastric cancer tissues and related with the poor prognosis of patients with gastric cancer. Overexpression of HNF4γ promotes the proliferation and remains the stemness of gastric cancer cells by upregulating the expression of CD44.
