Objective To study role of MDC/CCI22-CCR4 axis in mouse milky spots with peritoneal carcinomatosis of gastric cancer. Methods We examined the expression of CCR4 in 615 Mouse gastric cancer cell (MFC) lines by RT-PCR and Western-blot; Peritoneal metastasis model on the 615mouse was established by intraperitoneal injection of 0.2 ml MFC cells(1×104 cells). Dil fluorescence was used to observe the transfer process and section of MFC. Immunohistochemistry was conducted to detect the expression of CCR4 and CCL22 in omental milky spot; the structure of Milky spot was observed by scanning electron microscopy. Mice were randomly divided into 2 groups, namely, the saline control group (received saline) and MFC group. The concentration of CCL22 in ascitic fluid was measured in the 615 mice injected MFC after 6,8,10 days and in the saline group. Results MFC first metastasizes to the milky spot on the omentum, the expression of CCR4 and CCL22 were observered in the milky spot. The surface layer cells in milky spot consisted of discontinuous mesothelial cells and mainly macrophages and lymphocytes. The average value of CCL22 was 43 pg/ml and 364 pg/ml respectively in saline control group and MFC group.Conclusions MDC/CCL22-CCR4 axis plays an important role in the development of peritoneal carcinomatosis in mouse gastric cancer.

Objective To investigate the quality of life and analyze related factors of all the disabled at the entry of the Home Service Program in Zhabei district, Shanghai. Methods All the disabled were surveyed using the Chinese version of Short-Form 36 Health Survey(SF-36). Results 280 disabled people finished the survey, the total score was (59.72±20.03). There were significant differences in the scores among different ages, types of disabilities and status of subsistence allowances (P<0.01). The age was negatively correlated with quality of life (P<0.01). The education degree and the status of subsistence allowances were positively correlated with quality of life (P<0.05, P<0.01).Conclusion People with disability have poor quality of life in Zhabei district, Shanghai.

Objective To find out the cerebral blood flow velocity and its relationship with attention and execu?tion function in patients with major depressive episode. Methods A total of 70 patients with major depressive episode and 65 healthy controls were included. The 24 items Hamilton depression scale (HAMD-24) was adopted for patients' depressive symptoms assessment. The Cancellation Test (CT) and Wisconsin Card Sorting Test (WCST) were adopted for cognitive function assessment. And the blood flow velocity of cerebral arteries were detected by transcranial Doppler ul?trasonography (TCD). Results Compared with the controls, the patients showed significantly slower average blood flow ve?locity in basilar artery, left middle cerebral artery, right middle cerebral artery, left anterior cerebral artery and right ante?rior cerebral artery (P<0.05). Compared with those in the controls, the net score of each stage and the total net score of CT were significantly lower in the patients, while the total number of responses, response errors, perseverative errors and the necessary response number to complete the first category of WCST were significantly higher (P<0.01). The blood flow velocity in the cerebral basilar artery (r=0.25), left middle cerebral artery (r=0.46), right middle cerebral artery (r=0.25) and right posterior cerebral artery (r=0.26) showed positive correlations with total net score of CT (P<0.05), and the cere?bral artery average blood flow velocity showed negative correlations with the total number of responses, response errors and perseverative errors of WCST in the patients (P<0.05). Conclusions Compared with healthy controls, patients with major depressive episode suffer from lower average cerebral artery blood flow velocity, bad attention and executive func?tion. The change of average cerebral artery blood flow velocity may be responsible for impaired cognitive function in epi?sode major depression patients.

Objective To establish an effective and stable rat model of skin-infection for evaluating the therapeutic effects of topical anti-infection drugs.Methods SD rats were subcutaneously injected with cyclophosphamide to induce immunosuppression,and then surgical incisions were made on both sides of the spine.The rat model of skin-infection was established by applying methicillin-resistant Staphylococcus aureas suspension to the incisions for two consecutive days,and evaluated by analyzing infection status,pathological changes and healing time.Results The development of pyogenic infection was detected in all of the rats.Compared with the non-cyclophosphamide treated group,the cyclophosphamide treated group showed a more severe infection both from the visual inspection and the microscopic observation,moreover,its healing time was delayed more than 10 days.Conclusion The skin-infection model was successfully established in immunosuppressed rats induced by cyclophosphamide,which could be applicable to the efficacy evaluation of anti-infection drugs for external use on skin infection.

Objective To summarize the experiences in using Bio-Gide and Bio-Oss for guided bone regener- ation in dental implantation.Methods In 28 cases of bone deficiency,Bio-Gide membranes were applied to cover alveolar defects filled with the Bio-Oss bone powder.In postoperative periodic follow-.up,the bone regeneration effect was observed by successive clinical and X-ray examination.Results 38 implants were inserted in the 28 patients and Bio-Gide membranes were used in the sites of the 38 implants.Alveolar bone defects were filled with new bone in 27 patients,1 implant loosed because of inflammation.37 implants had ideal osseointegration at stageⅡsurgery and were prosthetic rcconstructed successfully.No implant loosed during the observed period of 15 months to 4 years. Conclusion Bio-Gide and Bio-Oss have ideal effect of guided bone regeneration in dental implantation.

Objective To establish a new model of cardiac arrest (CA) in rats by transcutaneous electrical epicardium stimulation. Method Two acupuncture needles connected to the anode and cathode of a stimulator were transcutaneously inserted into the epicardium as electrodes. The stimulating current was steered to the epicardium and the stimulation was maintained for 3 minutes to induce CA. Cardiopulmonary resuscitation (CPR) was performed at 6 minutes after a period of nonintervention. Results The success rate of induction was 12/20 at the current intensity of 1 mA; and reached 20/20 when the current intensity was increased to 2 mA. The average time from the electrical stimulation to CA induction was (5. 10 ± 2. 81) seconds. When the electrical stimulation stopped, 18/20 rats had ventricular fibrillation and 2/20 rats had pulseless electrical activity. CPR was performed for averagely 207.4 ( ± 148.8) seconds. The restoration of spontaneous circulation was 20/20. The death rate within 4 hours after CA was 5/20, and the 72-hour survival rate was 10/20. There were only two cases of complications, a minor muscle contraction and a minor lung lobe injury. Conclusions The model of CA in rats induced by transcutaneous electrical epicardium stimulation is a stable model that requires low-intensity current and has fewer complications.

Objective To explore the clinical efficacy of laparoscopic transabdominal preperitoneal (TAPP) hernia repair and risk factors affecting postoperative complications.Methods The retrospective casecontrol study was conducted.The clinical data of 595 patients who received laparoscopic TAPP hernia repair in the First Affiliated Hospital of Soochow University from February 2008 to August 2016 was collected.Operations were performed by the same doctors' team.Observation indicators:(1) surgical situations;(2) postoperative situations;(3) follow-up situations;(4) risk factors affecting complications after laparoscopic TAPP hernia repair.Follow-up using outpatient examination and telephone interview was performed to detect the recovery time of non-restricted activity,postoperative complications and hernia recurrence up to February 2017.Measurement data with normal distribution were represented as (x)±s.The univariate analysis and multivariate analysis were done using the chi-square test and Logistic regression model.Results (1) Surgical situations:595 patients underwent laparoscopic TAPP hernia repair using the heavy meshes.Overall operation time and overall volume of blood loss were (55±25) minutes and (7±5)mL,including operation time of (50±20)minutes in 502 unilateral hernias and operation time of (81 ± 29)minutes in 93 bilateral hernias.Of 595 patients,34 had incarcerated hernia,the contents of hernia:greater omentum,small intestine and sigmoid colon were detected in 21,11 and 2 patients,respectively,with an incarcerated time of 2-21 hours;4 with incarcerated hernia induced small intestinal necrosis received laparoscopy-assisted small intestinal resection ± anastomosis,1 with sigmoid colon necrosis received necrotic sigmoid canal resection ± sigmoidostomy and 29 received repair after the contents restoration of hernia.Operation time and volume of intraoperative blood loss in 34 patients with incarcerated hernia were (84 ± 39)minutes and (12±6) mL.Thirteen of 595 patients (10 with indirect hernia and 3 with direct hernia) had recurrent hernia,and operation time and volume of intraoperative blood loss were (75±-26)minutes and (10± 5)mL.(2) Postoperative situations:time to initial exsufflation of 595 patients was (19± 12)hours.Of 595 patients,590 took fluid diet at 6 hours postoperatively and 5 undergoing enterectomy took fluid diet at 24 hours postoperatively.The pain score at 1 day postoperatively and duration of hospital stay were respectively 2.5± 1.4 and (2.1± 1.9)days.(3) Follow-up situations:of 595 patients,593 recovered non-restricted activity at 2 weeks postoperatively and 2 didn't recover non-restricted activity at 2 weeks postoperatively.Of 595 patients,542 were followed up for 6-60 months,with a median time of 31 months.Fifty-seven,25,13 and 1 patients were respectively complicated with seroma,surgical pain,urinary retention and enteroparalysis,they were improved by symptomatic treatment,and the same patient can have multiple complications.There were no severe complications which needed surgical intervention,such as vascular injury,damnify of intestinal canal and poke hole hernia.Of 2 patients with recurrence of hernia,1 with right indirect hernia had recurrence of direct hernia and then received Lichtenstein tension-free hernia repair,and 1 received treatment in other hospital.(4) Risk factors affecting complications after laparoscopic TAPP hernia repair:results of univariate analysis showed that age,diameter of hernia sac,incarcerated hernia,recurrent hernia,operation time and volume of intraoperative blood loss were related factors affecting complications after laparoscopic TAPP hernia repair (x2 =6.657,55.296,44.305,5.253,117.461,100.722,P＜0.05).Results of multivariate analysis showed that diameter of hernia sac ≥ 4 cm,incarcerated hernia,operation time ≥ 100 minutes and volume of intraoperative blood loss ≥ 10 mL were independent risk factors affecting complications after laparoscopic TAPP hernia repair (OR =3.610,11.315,12.401,7.346,95％ confidence interval:2.009-6.486,3.579-35.772,5.408-28.437,3.739-14.434,P＜ 0.05).Conclusion Laparoscopic TAPP approach for inguinal hernia is safe and effective,and diameter of hernia sac ≥4 cm,incarcerated hernia,operation time ≥ 100 minutes and volume of intraoperative blood loss ≥ 10 mL are independent risk factors affecting complications after laparoscopic TAPP hernia repair.
