Pancreatic adenosquamous carcinoma is a rare exocrine pancreatic cancer,and surgical treatment is the only promising method in survival time extension and life quality enhancement.In July 2013,1 patient with pancreatic adenosquamous carcinoma and sarcomatoid change was admitted to the Shaoxing People's Hospital.A cauda pancreatis cystic nidus was detected by computed tomography 1 year ago,and no any other clinical symptoms were detected.The left upper quadrant of the patient was glutted and unwell,and the levels of CA19-9 and CA125 were 3 630 kU/L and 645 kU/L,respectively.The results of computed tomography and magnetic resonance imaging showed that a huge cystic and solid tumor was located between the cauda pancreatis,the stomach and the spleen;the tumor was mainly cystic and rooted in the tail of the pancreas;the spleen,stomach and surrounding tissues were infiltrated by the tumor.The results of postoperative pathological examination showed that the tumor was pancreatic adenocarcinoma with squamous epithelial differentiation and sarcomatoid change;the invasive squamous carcinoma dominated stomach wall,and the sarcomatoid change dominated spleen and lymph nodes with partial squamous epithelial differentiation and surrounding lymph nodes metastases.Although the surgical resection was complete and the postoperative thymosin injection and traditional Chinese medicine were implemented,tumor recurred at postoperative month 5,and the patient was dead due to cachexia and pernicious anemia at postoperative month 8.The prognosis of patients with pancreatic adenosquamous carcinoma is poor,early detection and surgery are key points for curative effect enhancement.

Objective To investigate the feasibility and technique in laparoscopic cholecystectomy and exploration of common bile duct (CBD) in patients who have previous subtotal gastrectomy.Methods From January 2001 to October 2010,22 patients who had a history of subtotal gastrectomy received laparoscopic cholecystectomy and CBD exploration in our hospital.In addition,these patients received cholangioscopic lithotomy,electrohydraulic lithotripsy,T-tube drainage,or primary suturing of the CBD wound.Results The procedures were completed successfully in 18 patients.In 4 patients,conversion to laparotomy was necessary because of multiple stones in a stenosed CBD (n=1),severely congested CBD wall with edema (n=1),CBD carcinoma associated with impacted stones (n=1) or Mirzzi syndrome (n =1).T tube drainage was employed in 16 patients,and primary suturing in 2 patients at the end of the operation.There was no hemorrhage,biliary leakage or abdominal infection.At a mean follow-up of 13 (range 3 to 60) months there was no residual stone,biliary stenosis or cholangitis.In 3 patients Stone recurred,and another 3 patients were lost to follow-up.Conclusions A history of subtotal gastrectomy is not a contradiction to laparoscopic cholecystectomy and CBD exploration.With choledocoscopy,surgery can be safe and feasible even for patients with previous gastectomy.

Objective To explore the bias between the real pressure and the measured values when handheld pressure gauge (HPG) was used to monitor intermittently the pressure in the intubation balloon,so as to provide some measures for the correct use of HPG.Methods In the first part of the study,HPG was used to measure the pressure with the balloon connected with a three-way tube with which to control the inflation and deflation in a laboratory to measure the pressure in the air bag.After gaining the deviation in this in vitro experiment,it was tested and verified in vivo in adult patients undergoing endotracheal intubation.Results After 132 times of measurements,it was found that measurement with a HPG might result in an inherent loss (3.928 ± 0.291) cmH2O (1 cmH2O=0.098 kPa,t =155.273,P =0.000) between inflation value [(30.000 ± 0.000) cmH2O] and measured value [(26.072 ± 0.291) cmH2O].In addition,after 214 times repeated measurements,the pressure loss during disconnection of the gauge was as high as (1.196 ± 0.954) cmH2O (t=18.348,P=0.000) between filled values [(30.000 ± 0.000) cmH2O] and measured values [(28.804 ± 0.954) cmH2O] and it was named as error loss.At last,the total error was verified by clinical test,and it was (5.270 ± 2.583) cmH2O (t=29.632,P=0.000) between pressure of filled value [(30.000 ± 0.000) cmH2O] and measured value [(24.730 ± 2.583) cmH2O].Conclusions When the balloon pressure was Monitored intermittently with HPG,the real value should be the measured value plus the error.In addition,subglottic aspiration should be done before the connection of the balloon to the gauge to prevent the secretions on the cuff falls into the deeper airway,and to maintain the cuff pressure at 30 cmH2O.

Objective To evaluate the changes of platelet-derived growth factor(PDGF) and vascular endo-thelial growth factor(VEGF) in infectious and autoimmunity diseaases. Methods The growth factors were measured by ELISA in 149 patients for seven times in different periods,and the levels and duration were compared. Results PDGF was (6.32±2.54) μg/ml and (2.57±1.65) μg/ml (P<0.05), and VEGF was (179.5±53.30) ng/ml and (221.4±70.04) ng/ml(P<0.05) in the two groups before treatment;There was statistical significance in dif-ferent time points between groups and within groups for PDGF(P<0.05) and significant difference for time chan-ging to the peak and changed duration between two groups for VEGF(P<0.05). For the two groups,the peak time of PDGF were (2.6±1.1) and (5.4±3.3) days;The peak time of VEGF were (2.4±0.7) and (7.2±3.3) days respectively(P<0.05 for each). However in the two groups, the change duration were (6.7±3.1) and (15.4±6.1) days for PDGF and (8.1±3.4) and (16.7±7.2) days for VEGF (P<0.05 for each). Conclu-sions There is significant difference for serum levels of PDGF and VEGF and the level change duration as well in the two groups, which maybe correlated with inflammatory nature and outcome.

Objective To investigate the peripheral blood cytopenias in patients with portal hypertension complicated with splenomegaly. Methods The clinical data of 309 patients with portal hypertension who had been admitted to our department from January 1991 to December 2006 were retrospeetively analyzed. Results Of all patients, 278 showed peripheral blood cytopenia, ineluding 71 with paneytopenia, 48 with leukocyte and platelet decrease, 25 with erythroeyte and platelet decrease, 33 with leukocyte and erythroeyte decrease, 28 with platelet decrease, 26 with leukocyte decrease, and 47 with erythrocyte deerease. The number of blood cells increased significantly after splenectomy ( t=6.53, P<0.01). The whole blood cells of the remaining 31 patients without hematocytopenia were normal. Conclusions Patients with portal hypertension eomplieated with splenomegaly do not always accompany peripheral blood eytopenia. Peripheral blood cytopenia is one of the complications of splenomegaly, hut it dose not always appear. Splenectomy is effective in the treatment of hematocytopenia. The reason for some patients do not have peripheral blood cytopenia may be related to the slight pathological changes of spleen and severe hyperplasia of bone marrow.

OBJECTIVE: To study the clinical value of polysomnography (PSG) and ApneaGraph (AG200) in the diagnosis evaluation of obstructive sleep apnea hypopnea syndrome (OSAHS). METHOD: From January to December in 2012, 67 OSAHS patients diagnosed by PSG were examined by AG200. The apnea hypopnea index (AHI), hypopnea index (HI), apnea index (AI), the lowest oxygen saturation (LSaO2) was were detected and the results were analyzed statistically. RESULT: Significant differences were observed in AI, AHI, LSaO2 between AG200 and PSG (P < 0.05, respectively). No statistically significant difference was found in HI. The differences in HI between AG200 and PSG were not significant (P > 0.05). AHI, HI and LSaO2 was were significantly correlated between AG200 and PSG (r = 0.870, 0.743, 0.374, 0.716, P < 0.01). CONCLUSION AG200 could not replace PSG but could identify the level of upper airway obstruction.

Objective To explore the efficacy and safety of 980 nm diode laser therapy for treatment of benign prostatic hyperplasia (BPH). Methods Data of 170 patients with BPH treated with 980nm diode laser system were reviewed. The mean operative time, blood loss, surgical complications, the international prostate symptom score (IPSS), bladder residual urine volume and flow rate changes were collected and analyzed. Results One hundred and seventy cases were safe during the perioperative period. The average operation time was (74 ± 11) min, surgical removal of prostate tissue mass of (54±12) g, blood loss (72±11) ml. There was no TUR syndrome occurred. 170 patients were followed up 2 to 24 months. The IPSS decreased from preoperative 25.0±5.5 to 9.0±2.5. The maximum flow rate increased from preoperative (6.2±2.3)ml/s to post-operative (17.4±3.5) ml/s. The residual urine volume decreased from preoperative (210.0±25.6) ml to postoperative (25.2±4.6) ml. All the differences were statistically significant (P＜0.05). Conclusion Transurethral vaporization of 980 nm diode laser could be a safe and effective treatment modality for BPH.
