The outpatient service system at Shanghai Sixth People's Hospital came into use since April 2009.Data from Jan.2010 to Oct.2010 and interviews with employees of department in question showed a rapid growth of outpatient appointments,a poor handling of outpatients absenteeism,and poor integration among the platforms of the appointments.The development of outpatient services depends on behavioral change of both medical workers and consumers.Some measures could be employed to improve outpatient appointment within the current mechanism.

Robotic system helps surgeons in performing surgery. Currently Da Vinci system is the most popular. Da Vinci system has been used for the stomach and bowel diseases in 27 cases(18 cases of stomach and 9 cases of colon and rectum) in the Zhongshan Hospital, Fudan University. Accurate preoperative staging is crucial, and Da Vinci system is advantageous in lymph node dissection, preservation of nerve plexus, and complete resection of mesorectum. Adoption of gastrointestinal tract reconstruction technique should depend on the operation and experience in surgery. Though Da Vinci system has limitations and the cost is high, it is believed to be the future trend.

ObjectiveTo observe the clinical effects of mirabilite external application and neostigmine injection at Zusanli acupoint combined with Xuebijing intravenous injection on patients with severe sepsis.Methods A history-prospective controlled study was conducted. Patients with severe sepsis admitted to the Fourth People's Hospital of Jiangsu University from January 2012 to November 2015 were enrolled. Twenty-one cases admitted from January 2014 to November 2015 were assigned as a research group and treated with application of mirabilite external application, Zusanli acupoint injection of neostigmine combined with intravenous Xuebijing injection; 22 patients with Xubijing treatment from January 2012 to November 2015 were included in a Xubijing group; 21 patients with routine therapy from January 2012 to November 2013 were included in a control group. The changes of white blood cell count (WBC), C-reactive protein (CRP), procalcitonin (PCT), mean arterial pressure (MAP), oxygenation index (OI), serum creatinine (SCr), acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) score, sequential organ failure assessment (SOFA), gastrointestinal function score, blood platelet count (PLT), plasma prothrombin time (PT), activated partial thromboplastin time (APTT), and D-dimmer in three groups before and after treatment were observed; the length of stay in ICU and the 28-day mortality were compared among the three groups. Results Compared with those before treatment, WBC, PCT, CRP, SCr, APACHE Ⅱ score, SOFA score, gastrointestinal function score, APTT, PT, and D-dimer were all obviously lower after treatment for 7 days in various groups; OI, MAP, PLT were significantly higher, and the improvement degree of WBC, PCT, CRP, SCr, APACHE Ⅱ score, SOFA score, gastrointestinal function score, OI in research group was more significant than those of control group and Xubijing group [WBC (×109/L): 7.52±0.75 vs. 12.87±4.13, 10.88±0.66, PCT (μg/L): 1.14±0.55 vs. 6.32±1.39, 3.47±1.94, CRP (mg/L): 21.0±9.2 vs. 65.0±13.6, 35.0±13.9, OI (mmHg, 1 mmHg = 0.133 kPa): 357.0±20.4 vs. 295.0±20.4, 309.0±21.4, SCr (μmol/L): 7.89±2.35 vs. 14.33±9.17, 11.27±4.65, APACHE Ⅱ score: 10.38±0.75 vs. 18.27±2.57, 13.09±4.10, SOFA score: 1.05±0.66 vs. 6.01±2.33, 3.26±1.03, gastrointestinal function score: 0.31±0.11 vs. 2.01±0.46, 1.85±0.29, all P < 0.05], the improvement of PLT, APTT, PT, D-dimer indicators in the research group was more significant than those in control group, but the above improvement compared with that in Xubijing group, no statistically significant difference was found [PLT (×109/L): 220.32±32.44 vs. 105.56±44.03, 170.56±54.03, APTT (s): 30.16±5.23 vs. 39.09±10.11, 29.56±6.85, PT (s): 10.74±1.25 vs. 13.56±4.65, 10.05±1.44, D-dimer (mg/L): 1.13±1.98 vs. 4.03±2.65, 1.13±0.54]. The length of stay in ICU was shortened in research group than that in control group and Xubijing group (days: 13.23±9.45 vs. 25.22±15.46, 18.56±10.33, P < 0.05); the 28-day mortality was significantly lower in the research group than that in the control group [28.6% (6/21) vs. 47.6% (10/21), P < 0.05], but there was no statistically significant difference compared with that in Xubijing group [28.6% (6/21) vs. 31.8% (7/22), P > 0.05]. Conclusions The treatment of mirabilite external application and neostigmine injection at Zusanli acupoint combined with Xuebijing intravenous injection can obviously improve the clinical symptoms, blood coagulation indexes and organ functions, reduce the levels of inflammatory indexes, shorten the time of the length of stay in ICU and elevate the survival rate of patients with severe sepsis.

BACKGROUND:Currently, fibroblast-like synoviocytes from the synovial tissue of patients with rheumatoid arthritis or adjuvant arthritis rats are isolated and cultured mainly using enzyme digestion method, but tissue explant adherent method is rarely reported in primary culture. OBJECTIVE:To establish a culture method of fibroblast-like synoviocytes from adjuvant arthritis rabbits and to investigate cell biological characteristics. METHODS:Rabbit models of adjuvant arthritis were prepared by injected with adjuvant at multiple sites and times, the knee synovial tissues were obtained, and fibroblast-like synoviocytes were separated and cultured by the tissue explant adherent method. Furthermore, the cell morphology was observed. The cell proliferation was measured using cell counting kit-8 assay, and the expression of Vimentin was detected by immunofluorescence.RESULTS AND CONCLUSION:The primary cultured rabbit synoviocytes were long spindle fiber-like and coincided with the fibroblast-like synoviocytes. Moreover, cells were positive for Vimentin. In conclusion, fibroblast-like synoviocytes from rabbits with adjuvant arthritis are successfully isolated and cultured by the tissue explant method.

Objective To explore the dysfunction of dendritic cells (DC) related to TGFβ reversed after blocking the TGFβ signal pathway by recombinant adenovirus vector encoding for Smad7.Methods Smad7 by recombinant adenovirus vector was transfected into dendritic cells.Expression of immunologic phenotypes was detected by FCM,and CTL activity induced by DC was compared.Results The DC modified with Smad7 still expressed high adhesiveness factor related to maturation even if existing exogenous TGFβ1,which was significant statistically compared with DC transfected with control adenoviral vector (P <0.01).Even if existing exogenous TGFβ1,the DC modified with Smad7 pulsed with soluble antigen associated with Lewis pulmonary carcinoma could still induce potent CTL activity against Lewis pulmonary carcinoma,which showed significant difference with DC-Ad-c (P <0.01).Conclusion The inhibitory effects on function of DC of TGFβ may be reversed by blocking the Smad signal of TGFβ pathway.
