Objective To explore the relationship between life events and depression of patients with primary sjgren's syndrome (PSS).Methods 80 patients with PSS complicating depressive disorder were tested by self-rating depression scale(SDS) and life event scale (LES),and compared with the control group including 80 PSS patients with non-depressive disorder matched with age and sex.Then the correlation between SDS and LES were analyzed.Results The total score of life events (32.72 ± 13.93),the score of negative life events (24.36 ±11.24),the score of SDS(58.60 ± 16.78) and the frequency of life events(91.3％) in the research group were higher than those in control group(P ＜ 0.05),but the positive life events score (7.15 ± 5.84) was lower than that in control group (9.76 ± 7.29),and there was statistically significant difference between the two groups (P ＜ 0.05),there were more negative life events,especially on the aspects of family,work and study in the research group.There was positive correlation among the negative life events score,total score of life events and SDS score in the research group(P＜ 0.01),meanwhile,negative correlation was revealed between the score of positive life events and SDS score in the research group(P ＜ 0.05).Conclusion Patients with PSS complicating depressive disorder experienced more negative life events which play an important role in depression of patients with PSS.

Objective To characterize the inheritance of erythropoietic protoporphyria (EPP) by detecting the mutations of ferroehelatase (FECH) gene in a Chinese family with EPP. Methods Peripheral blood samples were obtained from 4 patients and 3 unaffected individuals in a family with EPP, as well as from 50 unrelated healthy human controls. PCR was performed to amplify all the 11 exons and flanking sequence of FECH gene followed by direct sequencing. Results A splicing mutation,I.e., IVS3+1G→A, was identified in the proband as well as his symptomatic sister, cousin, grandfather and asymptomatic mother, but not in his asymptomatic father, grandmother, or unrelated healthy controls. The genotypes IVS1-23 T/C and IVS3-48 C/T were noted in the proband, his father, sister, cousin and grandfather, but absent in his mother or grandmother who carried IVS1-23 C/C and IVS3-48 T/T genotypes. Conclusions A novel splicing mutation is found in the FECH gene in a Chinese EPP family, which, together with two lowly expressed alleles IVS1-23T and IVS3-48C, is likely to be responsible for the clinical phenotype of EPP in this family.

Background and purpose: Paclitaxel is believed to be efficient in treating malignant ascites in gastric cancer. However, researches are still needed to get more evidence. The aim of this study was to discuss the efficacy and safety of the treatment of malignant ascites in gastric cancer with paclitaxel. Methods: Six cases of late phase gastric cancer patients were enrolled into the study, paclitaxel 60 mg/m~2 and 1 500-2 000 mL natural solution were administered via intraperitoneal injection, qw, for a of total 2-4 weeks. Efficacy and toxicity were determined according to WHO criteria. Results: Five (5/6) had complete response, and one (1/6) with partial response. The malignant ascites recession time was 0.5-10 months, overall survival time 2-10 months, 4 cases suffered grade Ⅰ-Ⅲabdominal pain, 4 cases grade Ⅰ leucopenia, 3 cases grade Ⅰ hair loss, 1 case grade Ⅰ liver injury (with past history of hepatitis). Conclusion: Paclitaxel is effective and relatively safe to treat malignant ascites of gastric cancer.

Objective To explore the effect of the use of flap transplantation combined with Masquelet tech-nique in the repair of long bone accompanied with soft tissue defect. Methods The retrospective study includes 16 cases of bone defects over 6.0 cm combined with soft tissue defect from March,2013 to March,2016,13 males and 3 females, of which the ages range from 16 to 65 years. The length of bone defect ranged from 6.0 to 12.0 cm, with an average of 8.5 cm,while the wound defect ranged from 5.2 cm×3.5 cm to 16.0 cm×7.5 cm. There were 8 cases out of 16 involve an infection:3 cases of Staphylococcus aureus(including 1 MRSA),2 cases of Staphylococcus epidermidis, 2 cases of Enterobacter cloacae, and 1 case of Acinetobacter baumannii. The 1 stage surgery in all patients admitted to hospital after complete debridement and external fixation, the clean wounds with bone defect received antibiotic-impregnated bone cement filling operation and a flap transplantation or transposition directly after the debridement, but the infected wounds received vacuum sealing drainage treatment firstly, associated with adequate use of antibi-otics for 1-2 weeks and then the bone cement filling and flap transplantation with infection totally controlled.After 8-12 weeks, we conducted the secondary internal fixation surgery replacing antibiotic-impregnated bone cement with autogenic cancellous bone, vancomycin artificial bone as well as rhBMP-2. All the cases were followed for 6 to 18 months. Results All patients with primary surgery are effectively controlled after 1-4 weeks of anti-infection treat-ment exclusive of the case with MRSA.As the condition of the patient with MRSA relapse,we changed to convention-al treatment: placed a continuous irrigation and suction equipment instead of the bone cement filling, the wound healed completely without fistula formation of osteomyelitis in 6 months after the treatment of Ilizarov technique. All transplantation and transposition flaps survived. As for those who received a secondary bone graft operation, all achieved a bony union in a period of 4-6 months. Conclusion The combination of flap transplantation and Masquelet technique is an effective method to repair limb long bone and soft tissue defect currently.

Objective To compare internal fixation with hallow compression screws combined vascularized bone graft(observation group) with only three hallow compression screws(control group) in young patients' Garden III and IV femoral neck fractures. Methods The patients with femoral neck fracture were treated from January, 2004 to December, 2013 were retrospectively reviewed. A total of 417 displaced femoral neck fractures in young and mid-dle-aged patients were long term followed-up. One hundred and thirty-seven patients were underwent open reduction and internal fixation with 3 hallow compression screws combined with a greater trochanter bone graft supported by the profound branch of medial circumflex femoral artery;280 patients were treated by closed reduction with 3 hallow com-pression screws. Results Patients had been followed-up for 5-12 years. At the last follow-up point, the Harris score of flap in observation group(93.68±5.12) were higher than that in control group(92.53±6.12), while it was no sta-tistical difference(P>0.05). It was 0.7％of nonunion incidence rate in the observation group, and incidence of avascular necrosis of femoral head was 6.6％, and incidence of femoral neck shortening was 8.8％. In the control group, inci-dence of avascular necrosis of femoral head was 14.6％, nonunion incidence rate was 4.6％, and incidence of femoral neck shortening was 22.5％. The differences between two groups was statistically significance( P<0.05). Conclusion The open reduction and internal fixation which is hallow compression screws in combination with a greater trochanter bone graft supported by the profound branch of medial circumflex femoral artery is an optimal treatment for young adults with Garden III and IV femoral neck fractures.

Stroke at the acute stage is a major cause of disability in adults, and is associated with dysfunction of brain networks. However, the mechanisms underlying changes in brain connectivity in stroke are far from fully elucidated. In the present study, we investigated brain metabolism and metabolic connectivity in a rat ischemic stroke model of middle cerebral artery occlusion (MCAO) at the acute stage using F-fluorodeoxyglucose positron emission tomography. Voxel-wise analysis showed decreased metabolism mainly in the ipsilesional hemisphere, and increased metabolism mainly in the contralesional cerebellum. We used further metabolic connectivity analysis to explore the brain metabolic network in MCAO. Compared to sham controls, rats with MCAO showed most significantly reduced nodal and local efficiency in the ipsilesional striatum. In addition, the MCAO group showed decreased metabolic central connection of the ipsilesional striatum with the ipsilesional cerebellum, ipsilesional hippocampus, and bilateral hypothalamus. Taken together, the present study demonstrated abnormal metabolic connectivity in rats at the acute stage of ischemic stroke, which might provide insight into clinical research.
