Primary squamous cell carcinoma of the thyroid gland is a rare malignant tumor with strong invasive ability and high malignancy.It is difficult to early diagnose and the radical surgery is hard.The prognosis is very poor with the median survival of six months approximately.The surgery is a primary treatment.For patients who can not be treated by surgery radiotherapy which is a feasble way.Respectively at a certain extent can improve the control rate,however chemotherapy does not show obvious advantages.

Objective To summarize the experience of surgical of complete pulmonary venous connection in neonates,and analyze the risk factors.Methods Between June 2010 to June 2016,21 consecutive neonates under went surgical correction of total anomalous pulmonary venous connection.There were 15 males and 6 females at mean age 20d,and the mean weight was 3.5kg.There were 10 patients with supracardiac,of which 6 patients with intracardiac,4 patients with infracardiac,and 1 patients with mixed.Clinical variables possibly associated with death were examined using Logistic regression analysis.Results There were 4 operative deaths(19％),2 patients with supracardiac,1 patient with intracardiac,1 patient with infracardiac.2 were died of low cardiac output syndrome,and 2 died of pneumonia.Logistic regression analysis showed that preoperative pulmonary infection,anatomic classification,aortic clamping time,weight were risk factors of operation.Conclusion Total anomalous pulmonary venous connection operation in neonates can obtain satisfactory results.Preoperative pulmonary infection,anatomic classification,aortic clamping time,weight are risk factors for operation.

Objective To analyze effects of different anesthesia procedures on heart rate variability(HRV) as an index of autonomic nervous activity and hemodynamics during CO2 pneumoperitoneum pressure in laparoscopic cholecystectomy(LC).Methods 45 patients of ASA I or II phage scheduled for LC were divided into general anesthesia group(Group I,Control Group),general anesthesia combined with esmolol group(Group II) and general anesthesia combined with epidural block group(Group III) according to operation date.HRV,HR and MAP were measured before anesthesia(T1),before pneumoperitoneum(T2) and at 5 min(T3),10 min(T4),20 min(T5),30 min(T6) after pneumoperitoneum.Results As compared with pre-pneumoperitoneum(T2),low frequency(LF),low frequency/high frequency(LF/HF) in the Group I increased significantly(P0.05).Comparisons among the three groups,LF,LF/HF in the Group I at all time points after pneumoperitoneum were significantly higher than those in the II and III Group(P0.05).Conclusions Esmolol can relieve stress reaction induced by pneumoperitoneum,but it can't completely block increasing of sympathetic nerve activity;using general anesthesia combined with epidural block in LC can inhibit sympathetic nerve excitation,sustain automatic never stability.

Objective To evaluate the predictive performance of the target controlled infusion (TCI) system for propofol using Marsh pharmacokinetic parameters in the elderly patients. Methods Sixteen ASA grade I - Ⅱ patients of both sexes (9 male, 7 female) aged 65-75 yr weighing 49-76 kg scheduled for elective lower abdominal surgery were enrolled in this study. The patients were unpremedicated. Right internal jugular vein was cannulated for drug and fluid administration and left radial artery was cannulated for BP monitoring and blood sampling. Anesthesia was induced with TCI propofol (target plasma concentration was set at 3 ?g?ml-1 ) and TCI fentanyl (target plasma concentration set at 2 ng?ml-1 ) . Tracheal intubation was facilitated with succinyl choline 1.5mg?kg-1 . The patients were mechanically ventilated ( VT 8 ml?kg-1 , RR 10 bpm) . Anesthesia was maintained with TCI propofol and fenlanyl and intermittent i.v. boluses of vecuronium. The target plasma concentration of propofol and fentanyl were the same as that for induction. MAP, HR, SpO2 and BIS were continuously monitored during operation. Blood samples were taken at 5, 10, 15, 20, 30, 45, 60, 90, 120 min during TCI of propofol for determination of plasma propofol concentration with HPLC. The predictive performance was evaluated by PE% [measured concentration (Cm) - predicted concentration (Cp)] /Cp ? 100% , MDPE, MDAPE and wobble. Results BIS was maintained between 38-55. The MDPE was 6%, MDAPE 14% and wobble 18 % with this TCI system incorporating Marsh pharmacokinetic parameters for propofol. Conclusion The TCI system incorporating Marsh pharmacokinetic parameters for propofol is acceptable for elderly patients.

Methods A multicenter, prospective and open-labeled trial was conducted. A total of 1522 patients were enrolled at the beginning, and only 1324 were evaluabled at the endpoint. The duration of treatment was 7-14 days. During the treatment and follow-up periods, we recorded any unexpected symptoms and abnormal laboratory tests. At last,we evaluated its efficacy and safety. Results The total effective rate of cefmetazole was 79. 8% (1056/1324). The total bacterial eradication rate was 75.0% ( 342/456 ) . The bacterial eradication rates of klebsiellar pneumonia, escherichia, staphyloccocus aureus and anaerobic bacteria were 78.2% (97/124), 80.8% (80/99), 89.0% (81/91), 9/11,respectively. Conclusions Cefmetazole is effective and safe in the treatment of aspiratory pneumonia.

Objective To compare the effect of transthoracic contrast echocardiography (cTTE) with transesophageal contrast echocardiography (cTEE) for detecting right to left shunt (RLS) in patients with patent foramen ovale (PFO). Methods The prospective study was conducted in 29 consecutive patients with PFO who suffered from cryptogenic stroke and/or migraine. Contrast echocardiography was performed in all 29 patients. The cTTE was performed using transducer with second harmonic imaging modality (transmitting frequency 1.7 MHz, receiving frequency 3.4 MHz). The cTEE was performed using transducer with frequency 7 MHz. Ten milliliter saline solution of contrast were rapidly administrated through an antecubital vein. According to whether microbubble (MB) appearing in left atrium after complete opaciifcation of right atrium within the ifrst 3 circles, the results were classiifed by a four-level semi-quantitative categorization:Level 1 (no PFO-RSL), no MB in left atrium; Level 2 (small PFO-RSL) 1-10 MBs; Level 3 (medium PFO-RSL) 10-30 MBs;Level 4 (large PFO-RSL)>30 MBs. Results The total detection rate of PFO-RSL was signiifcant different between cTTE and cTEE (86.2%vs 55.2%,χ2=5.711, P=0.017). In cTTE there were 4 cases at level 1, 1 case at level 2, 5 cases at level 3 and 19 cases at level 4. In cTEE there were 13 cases at leverl 1, 2 cases at level 2, 6 cases at level 3 and 7 cases at level 4. The comparison of semi-quantitative grading derived from cTTE and cTEE was also signiifcant different (Wilcoxon signed ranks test showed Z=-3.789, P=0.000). Conclusions The efifciency in detection of PFO-RLS with cTTE was better than with cTEE. Compared with cTEE, cTTE was easier in practice and brought less discomfort and complications to patients.

Objective To explore the status of early postoperative social relationship quality and hope level in patients with breast cancer and analyze the correlation between them. Method A questionnaire survey was conducted among 100 patients with breast cancer using the social relationship quality scale and Herth hope scale. Results The total score and expected total score of early postoperative social relationship were (47.86±6.10)and (30.81±1.86), respectively. There was a positive correlation between the two groups (r=0.324,P<0.05). Conclusions The quality of social relations in the postoperative patients with breast cancer is positively correlated with the level of hope. Nursing staff should give breast cancer patients hope and strength at the same time, helping them understand and use social relations to improve the quality of life.

In this study, pEGFP-N1 was chosen as the reporter plasmid and transferred into Ctenopharyngodon idellus kidney (CIK) cells by electroporation, and the optimal electroporation conditions were determined by testing the transfection efficiency with different voltages, pulse times, plasmid amounts, and numbers of shocks. The results showed that the maximum electroporation efficiency was achieved under the following conditions in a 0.2 cm electroporation cuvette containing CIK cells (1.5 x 10(7)/mL, 200 microl): electric voltage 200 V, pulse time 45 ms, plasmid 30 microg, and one electric shock. The total genomic RNA of grass carp reovirus (GCRV) was extracted in this experiment and reversely transcribed into cDNA, which was used to amplify the gene segment of GCRV non-structural protein NS26 using designed specific primers. The PCR product was recombined into pEGFP-N1 vector. The fusion protein EGFP-NS26 was successfully and efficiently expressed in the CIK cells by electroporation, which was confirmed by both fluorescent imaging and Western blot analysis. This experiment laid a foundation for further functional studies of the non-structural protein NS26 of GCRV.

BACKGROUND: There are no ideal substitutes for meniscus. Meniscel allograft transplantation has become a feasible method to retain maniscal function following injury. Currently, the meniscus conservancy methods include fresh meniscus, low temperature preserved meniscus; freeze-dried meniscus.OBJECTIVE: To observe the long-term effects of meniscus allograft transplantation by different methods.METHODS: A total of 70 adult New Zealand rabbits were used, and 30 were selected as meniscus donors. The remaining 40 rabbits were divided into 4 groups (n=10): after meniscectomy, control group was not treated; fresh group underwent fresh meniscus allograft transplantation; low temperature group underwent low temperature preserved meniscus allograft transplantation; freeze-dried group underwent freeze-dried meniscus allograft transplantation. Of 30 donors, 10 received fresh meniscus transplantation, and the other received temperature preserved meniscus and freeze-dried meniscus transplantation 1 week after low temperature and freeze dried preservation. The rabbits were sacrificed 12 months after surgery for gross and histological observation.RESULTS AND CONCLUSION: The meniscus allografts of rabbits healed well, and no rabbits died. Gross observation showed that the appearance and elasticity of fresh meniscus group was similar to normal meniscus; tibial plateau was covered well, with no additional wearing in the cartilage of tibial plateau or condyles of femur. In low temperature and freeze-dried preservation groups,the meniscus grafts healed well, but their volume was small and the elasticity was poor; tibial plateau was only partially covered.Pathological observation suggested that fresh meniscus group had orderly arranged collage fiber and similar chondrocyte appearance, number and distribution to normal meniscus, while sparse collagen fiber end small number of meniscus grafts were observed in the other groups. Results show that meniscal allogrefting can survive, retain certain function and structure and prevent the degenerative changes of the knee joint. Moreover, fresh meniscal grafts exhibit best effects, as the grafts following low temperature or freeze-dried preservation degenerate and their volume diminish 1 year following meniscectomy.
