Objective To evaluate the effects of ginsenoside Rg3 combined with XELDX regimen on advanced carcinoma of stomach.Methods Totally 93 postoperative patients with advanced gastric cancer were randomly divided into two groups:control group(n ＝ 53) who received only XELDX regimen,and study group (n＝ 40) who were treated with ginsenoside Rg3 + XELDX.The objective response rate,KPS score and serum VEGF levels in the two groups were detected.Results (1) Before treatment,treatment group and control group showed that serum VEGF levels were (387.63±159.74) μg/L and (378.56± 169.36) μg/L,respectively (P＜0.05).After 8 weeks of treatment,serum VEGF of the treatment group decreased to (207.74 ± 115.71) μg/L,the level of the control group VEGF decreased to (246.53 ±107.63) μg/L(P＜0.05).(2) The efficacy rate was 57.5％ (23/40) in treatment group and 45.3％(24/53) in the control group (P＞0.05).(3) KPS score increasing rate was higher in treatment group (65.0％) than in control group (39.6％)(x2＝5.87,P＜0.05).Conclusions Ginsenoside Rg3 combined with chemotherapy in advanced gastric cancer patients can reduce serum VEGF levels and improve the quality of life of patients.

Objective To investigate the causes, characteristics, diagnosis and treatment of severe acute pancreatitis (SAP) complicated with mental disorders. Methods The clinical data of 86 patients with SAP complicated with mental disorders who had been admitted to Union Hospital of Tongji Medical College from 2000 to 2007 were retrospectively analyzed. The causes, clinical manifestations, treatment and prognosis were analyzed. Results Of the 86 patients, 38 were caused by internal milieu disorder, 9 by pancreatic encephalopathy, 23 by infectious-toxic encephalopathy, and 16 by Wernicke encephalopathy. The manifestation of the patients with SAP complicated with mental disorders was complex, varied and nonspecific. Individualized treatment was applied to all patients after the analysis of the causes, and most patients recovered except 14 who died of hemorrhage or multiple organ dysfunction syndrome. Conclusions Internal milieu disorder should be first considered when patients have mental disorders which occurred at the early phase of SAP, then pancreatic encephalopathy should be considered. The infectious-toxic encephalopathy and Wernicke encephalopathy should beware of when the mental disorders occur in the late phase of SAP. Individualized treatment according to the causation and comprehensive treatment are effective in preventing and treating mental disorders which occurred in the course of SAP.

Objective To evaluate the effectiveness of domestic exogenous pulmonary surfactant (EPS)-Calsurf in treating full-term neonatal respiratory distress syndrome (RDS).Methods (1) From January 2011 to June 2012,154 full-term neonates with RDS were divided into Calsurf group (74 cases) and Curosurf group (80 cases),comparing differences in changes of arterial blood gas,the length of hospital stay,hospitalization expenses,duration of mechanical ventilation,inspired oxygen time,the incidences of complications and repeated EPS use rates between two groups.(2) In order to compare the effectiveness of different doses of Calsurf in treating full-term neonatal RDS,from July 2012 to March 2013,80 RDS patients who received Calsurf were divided into mild-moderate group (grade Ⅱ ～ Ⅲ on chest X-ray,50 cases) and severe group (grade Ⅳ on chest X-ray,30 cases).Furthermore,each group was divided into two subgroups,which were low-dosage(per-time 30 ～40 mg/kg) and high-dosage group (per-time 30 ～40 mg/kg).Results (1) Before administrating Calsurf and after administrating it at 0.5 h and 6 h,the pH,PaCO2 and PaO2 of RDS patients were no significant difference in two groups (P ＞ 0.05).(2) There were no significant difference between the duration of mechanical ventilation,inspired oxygen time,length of hospital stay in two groups (P ＞ 0.05).But the hospitalization expenses in Calsurf and Curosurf groups were 28.778 versus 31.827 thousand yuan,respectively,with the average reduction of 9.6％ in Calsurf group (P ＜ 0.05).(3) There were no significant difference between the morbidities and mortalities of multiple organ failure,persistent pulmonary hypertension,acute renal failure and pneumothorax in two groups (P ＞ 0.05).(4) In mild-moderate grade RDS patients,the low-dosage or high-dosage of Calsurf had similar effectiveness in improving bloog gas (P ＞ 0.05),the repeated Calsurf use rates of both subgroups were 16.0％ (4/25) and 20.0％ (5/25) (P ＞ 0.05).While in severe RDS patients,high-dosage Calsurf got a better effectiveness in improving bloog gas than low-dosage Calsurf(P ＜ 0.05).Meanwhile,the repeated Calsurf use rates of the low-dosage and high-dosage subgroups were 20.0％ (3/15) and 33.3％ (5/15),with a 40％ reduction in high-dosage subgroup.Conclusion (1) Both Calsurf and Curosurf can significantly improve the conditions of hypoxemia and hypercapnia,moreover,the length of hospital stay and duration of mechanical ventilation of both groups are similar,with less hospitalization expense in Calsurf group.(2) Both low and high-dosage Calsurf have similar curative effect on mild-moderate RDS,but for severe RDS,high-dosage Calsurf works better,reducing the repeated EPS use rate to some extent.

Objective To investigate the clinical efficacy of hemocoagulase for severe hemorrhagic cystitis (HC) following allogeneic hemotopoietic stem cell transplantation (HSCT). Methods Twenty patients undergoing allogeneic HSCT developed severe HC with an onset time of 14 to 70 days, all patients received the treatment of hemocoagulase (1 U ivgtt q12 h × 5 d). The urine speciments reserved before and after hemocoagulase were examined by naked eye and microscope to evaluate the efficacy. Results Twenty patients received the treatment of hemocoagulase. The HC was cured in 18 patients, improved in 1 patient and uncontrolled in 1 patient. For the patients with response, macroscopic hematuria disappeared at a median of 28 days (4-127 days) after the treatment. All procedures were tolerated well and no severe adverse effect was observed. Conclusion Hemocoagulase seems to be a safe and effective drug for severe HC following HSCT.

Objective To evaluate the clinical results of femoral-deep femoral crossover bypass in the treatment of long-segment unilateral iliac artery occlusive disease.Methods From July 1995 to December 2010,40 patients (28 males,12 females,aged from 66 to 90,with mean age of 73) with comprehensive unilateral iliac-superficial femoral arteriosclerosis obliterans were enrolled in this procedure.All patients suffered from unilateral common iliac,external iliac,common femoral,and superficial femoral arteriosclerosis obliterans.These patients were treated with femoral-deep femoral crossover bypass.Postoperative ankle-brachial index,blood flow velocity and patency rates in 5,7 and 10 years and limb salvage rates in 5,7 and 10 years were evaluated.Results There was no perioperative mortality nor extremity amputation.35 (87.5％ ) patients were followed-up from 1 to 13 years (mean 5.7 y).Anklebrachial index rose from preoperative 0.23 ± 0.10 to postoperative 0.55 ± 0.11 (t =15.91,P =0.000 ).Popliteal arterial velocity rose from preoperative ( 14 ±6) cm/s to postoperative (34 ± 10) cm/s (t =15.63,P =0.000) ; Tibial arterial velocity rose from ( 10 ±4) cm/s to (22 ±7) cm/s (t =15.71,P =0.000).The primary and secondary patency rates were 60.1％,44.3％,25.3％,and 93.5％,86.8％,57.9％ at 5,7 and 10 years,respectively.Limb salvage rates were 97.5％,95％,and 90％,at 5,7 and 10 years,respectively.Conclusions Femoral-deep femoral crossover bypass is safe and reliable in treating certain unilateral iliofemoral occlusive disease,especially for high-risk old patients or those who are not indicated for endovascular therapies or direct aortic approaches.

OBJECTIVETo study the variations of protein concentration in saliva stimulated and its effect on clinical diagnosis.

METHODSThe saliva from 33 normal controls and 73 patients with Sjögren syndrome (SS) who were stimulated with acid and not were collected. The concentration of beta 2 microglobulin (beta 2-mG), secretory immunoglobulin A (SIgA), and pH were measured by Radioimmunoassay, Rate Nephelometry and pH Detection Paper, respectively. SPSS 10.0 was used to determine the mean statistical differences among these groups.

RESULTSIn patients with SS, the concentration of beta 2-mG in saliva stimulated with Vc was significantly lower compared with that in saliva not stimulated (P < 0.01); In saliva stimulated with Vc, the concentration of beta 2-mG in patients with SS was higher than that in normal controls (P < 0.05). In normal controls, compared with that in saliva not stimulated, flow rate in saliva stimulated with 3% acetic acid and Vc was significantly higher (P < 0.01) and pH, concentration of beta 2-mG and SIgA were significantly lower (P < 0.01 and P < 0.05 respectively); there was a significant difference of flow rate, beta 2-mG, SIgA and pH in saliva between the subjects stimulated with 3% acetic acid and with Vc (P < 0.01).

CONCLUSIONSThe reason for the decrease of protein concentration in saliva stimulated may be the increase of flow rate caused by the decrease of pH or the decrease of pH itself. Protein detection of saliva stimulated in patients with SS is helpful in diagnosis, but the criterion is different between the saliva stimulated and not stimulated.
