The low survival rate of stem cells in the ischemic myocardium microenvironment is the bottle neck in treating ischemic diseases with stem cell transplantation.It is able to increase anti-apoptotic ability of the stem cells and promote their effective differentiation towards myocardial cells directly and indirectly by pretreating the stem cells with cytokines,drugs or chemical compounds,or modifying gene expression to promote cell adhesion,survival or angiogenesis for repairing ischemic myocardium and improving heart function after transplantation of the stem cells.

General practice is a clinical practice which integrates a variety of disciplines and aims at providing basic health care services for individuals, families and communities. General prac-tice in China is now experiencing increasing development. In 2011, the Academic Degrees Committee of the State Council approved of the addition of general practice under the category of clinical medicine, initiating the education of postgraduates with professional degree majoring in general prac-tice. Through analyzing supervisor instruction, curriculum, skill training and assessment of postgrad-uates majoring in general practice, this paper thoroughly explored its training mode.

Objective To investigate the characteristics and risk factors of abdominal lymph node metastasis in thoracic esophageal squamous cell cancer.Methods The clinical data of 586 patients with thoracic esophageal cancer who underwent surgery via transabdominal and transthoracic approaches between June 2009 and June 2014 at the Sichuan Cancer Hospital were retrospectively analyzed.All the patients received resection of esophageal cancer and lymph node dissection, and the transabdominal right thoracic approach or cervico-thoracicabdominal triple incision was selected according to the condition of patients.No.18, 19, 20 lymph nodes were dissected seperately and No.16, 17 and lesser curvature lymph nodes were separated.All the specimens of lymph nodes were detected by regular pathological examination.Measurement data with normal distribution were presented as x ± s and count data were described as rate.Comparisons of rate between 2 specimens and among the multiple specimens were respectively analyzed using the chi-square test and partition of chi-squared.The multivariate analysis was done using the logistic regression.Results The number of lymph node dissected in 586 patients was 12 524 with an average number of 20 ± 11 per case, and the rate of lymph node metastasis was 55.63％ (326/586).The number of mediastinal lymph node dissected was 7 012 with an average number of 12 ± 5 per case, and a rate of mediastinal lymph node metastasis was 40.96％ (240/586).The number of abdominal lymph node dissected was 5 512 with an average number of 9 ± 8 per case, and a metastasis rate was 31.74％ (186/586).The abdominal lymph node metastasis rate of the upper, middle and lower thoracic esophageal cancer were 13.73％ (14/102), 31.51％ (92/292) and 41.67％ (80/192), respectively, showing a significant difference among the above 3 indexes (x2 =25.91, P ＜ 0.05).The lymph node metastasis rate in No.16, 17, 18,19, 20 and lesser curvature lymph nodes were 12.80％ (75/586), 16.89％ (99/586), 1.71％ (10/586),0.68％ (4/586), 1.71％ (10/586) and 2.05％ (12/586), respectively, with a significant difference among the above 6 indexes (x2 =287.95, P ＜ 0.05).The results of univariate analysis showed that the tumor location,surgical procedure, T stage, N stage, G stage, pathological stage and mediastinal lymph node metastasis were risk factors affecting abdominal lymph node metastasis of thoracic esophageal cancer (x2 =24.02, 23.97, 37.87,136.85, 38.79, 7.70, 154.27, P ＜ 0.05).The tumor in the lower thoracic portion, N3 stage and stage Ⅳ were independent risk factors affecting abdominal lymph node metastasis of thoracic esophageal cancer in the multivariate analysis (RR =5.80, 2.36, 2.76, 95％ confidence interval: 1.022-1.813, 1.317-3.950, 1.652-12.351, P ＜ 0.05).Conclusions Abdominal lymph node metastasis is common in thoracic esophageal cancer in which No.16 and 17 lymph nodes predominate, and it is easy to occur in patients with lower thoracic esophageal cancer, and advanced N stage and pathological type.

Objective To analyze the clinical features, recurrent characters in patients with recurrent Tolosa-Hunt syndrome (THS). Methods The clinical data of 24 hospitalized patients with recurrent THS from January 2006 to May 2016 were collected The general features, clinical manifestations, disease courses, recurrent features, lab and imaging studies, treatment measures and outcoming of recurrent THS patients was investigated , and compared with 69 patients with first attack THS in corresponding period. Results Recurrent THS patients were 25.8%(24/93) of total THS. The male rate in recurrent group was significantly higher than that in first attack group: 66.7%(16/24) vs. 42.0%(29/69), P<0.05. The involved rate of trigeminal nerves in recurrent group was significantly lower than that in first attack group:16.7%(4/24) vs. 33.0%(23/69), P<0.05. The disease courses were from 3 months to 20 years. The total recurrent frequencies were from 2 to 10 times. The recurrence occurred in the same side in 18 patients, and in contralateral in other 6 patients. The intervals were from 3 months to 6 years, and average intervals were 1.9 years. Two patients recurred in hormone reduction, and 22 patients recurred in hormone withdrawal. All cases received MRI examination. Nineteen patients (79.2%) of them had lesions in cavernous sinus. 16 patients had one side lesions and 3 patients had bilateral lesions. The recurrent patients still had good responds to corticosteroids treatment. Conclusions Recurrences in THS are common, taking place in about 26%total patients, and usually at an interval of months or years from the initial attack. These recurrences may be ipsilateral, contralateral, or rarely, bilateral. Corticosteroids are still effective to recurrent cases.

Objective To investigate the clinical and image features of cerebral venous sinus thrombosis (CVST) presented as isolated intracranial hypertension.Methods The medical records of patients with diagnosis of CVST presented as isolated intracranial hypertension were reviewed.Clinical features and imaging data were retrospectively analyzed.Results Twenty cases of CVST were included,all these patients were clinically presented as isolated intracranial hypertension.The male to female ratio was 13:7,and the average age was (38.3 ± 11.7) years old.None of the patients was obesity.The visual acuity was lower than 0.1 in 42.5％ (17/40)of the eyes.Possible risk factors relevant to CVST were found in 11 cases (55％),including head trauma for 4 cases,autoimmune disease for 2 cases,and other causes of single case including spontaneous abortion,phlebitis,otitis media postoperative,trigeminal nerve microvascular decompression surgery and obstructive sleep apnea syndrome.Image analysis showed that lateral sinus thrombosis was involved in 85％ (17/20) of the patients,while superior sagittal sinus was involved in 35％ (7/20),and 65％ (13/20) of the patients were isolated lateral sinus thrombosis.Conclusions Young male predominance is found in CVST patients which presented as isolated intracranial hypertension but severe visual function loss.Risk factors such as head trauma are commonly found in these patients.Most of the patients are isolated lateral sinus thrombosis,with lateral sinus narrowing as the most common abnormal findings in magnetic resonance venogram.

To clone overexpressed gene from human gastric carcinoma cell SGC-7901, DDRT-PCR technique is used with human gastric epithelial cell GES-1 as control. After cloned into pGEM -T vector, YA61, one of the overexpressed genes, was analyzed by dot blot and was sequenced then. The sequence gotten was then compared to GenBank data and analyzed by NCBI ORF Finder. Dot blot results showed that the gene YA61 was overexpressed in human gastric carcinoma cell SGC-7901. NCBI's sequence similarity search indicated that the gene YA61 was a new gene sequence. Open reading frame analysis demonstrated that the gene YA61 had one complete open reading frame. In conclusion, the gene YA61 was a new gene sequence that was overexpressed in human gastric carcinoma cell SGC-7901.

BACKGROUND:C-reactive protein has been shown to rapidly increase during the occurrence of inflammation and tissue injury, and can indicate the degree of inflammatory reaction.
OBJECTIVE:To analyze the correlation between survival time and C-reactive protein in rabbits after transplantation of polytetrafluoroethene artificial trachea with support ring.
METHODS:The cervical trachea of rabbits was replaced by polytetrafluoroethene artificial trachea with support ring. Survival time of the rabbit, and the changes in serum C-reactive protein at 1-7 days after transplantation were observed. Linear regression was used to assess the univariate association between serum C-reactive protein and survival time.
RESULTS AND CONCLUSION:The linear correlation was observed between changes of serum C-reactive protein and survival time in rabbits with artificial trachea replacement operation. C-reactive protein levels in rabbits with<13 days of survival time were increased and positively associated with the number of days after transplantation. However, C-reactive protein levels in rabbits with>13 days were decreased and negatively associated with the number of days after transplantation. In rabbits with positive correlation and negative correlation, the median survival time and 95%confidence interval (CI) were respectively 10 days (95%CI 8.614-11.386 days) and 27 days (95%CI 23.970-30.030 days). The survival rate in negative correlation group was significantly higher than positive correlation group (x2=29.364, P<0.01). Results suggested that the prolonged survival time of rabbits after artificial trachea replacement operation was related to the decreased concentration of serum C-reactive protein.

Two hundred and four patients with diabetic nephropathy and depressive disorder were randomly assigned to the control group (40 cases), St.John's Wort extract (SWE) group(40 cases) ,SWE +psychotherapy group ( 40 cases), SWE + physicotherapy group ( 40 cases ) and SWE + psychotherapy +physicotherapy group (44 cases), all patients were treated for 12 weeks.The therapeutic effects were evaluated with Hamilton Rating Scale for Depression-17 (HAMD-17).The percentage reduction in HAMD scores in SWE + psychotherapy + physicotherapy group was the highest ( 86% ), and those for SWE, SWE +psychotherapy, SWE + physicotherapy and control groups were 47%, 55%, 60% and 13%, respectively (x2 =47.331, P =0.000).After 12 weeks of treatment, glycosylated hemoglobin(HbA1c) and urinary albumin excretion rate (UAER) were reduced in all 4 treatment groups compared with the control group.The levels of HbA1 c and UAER in SWE + psychotherapy + physicotherapy group were significantly lower than those in others ( F = 15.754,74.025, all P = 0.000).St.John' s Wort extract with psychotherapy and physicotherapy can efficiently improve the depressive disorder in type 2 diabetic patients with nephropathy, as well as control blood glucose and reduce UAER of patients.

Objective To investigate the effects of hypercholesteremia on the motor function of sphincter of Oddi (SO). Methods Thirty-two rabbits were divided into control group and experimental groups. In the control group, the rabbits were fed with normal diet. In the experimental groups, the rabbits were fed with normal diet + cholesterol for 4, 6 and 10 weeks. Myoelectric activity and pressures of SO were detected. All data were analyzed by t test. Results The serum total cholesterol and low density lipoprotein cholesterol were at a high level in rabbits which were fed with normal diet + cholesterol for 10 weeks (t=9.63, 11.38, P <0.05); basal pressure, pike pressure and amplitude of SO were significantly elevated (t=5.23, 6.34, 3.24, P < 0.05) ; the spike potential of SO changed to myoelectronic activity, with prolonged time period of myoelectronic activity, while the discharge rate was decreased (t=13.68, 10.18, P < 0.05). Conclusion Hypercholesteremia may change the motor function of SO and enhance its peristalsis to speed up the excretion of bile.
