Objective To observe the effect of intravenous administration of dexamethasone on airway complications after laparoscopic cholecystectomy (LC). Methods 66 patients who were treated with laparoscopic cholecystectomy in Wenling hospital of traditional Chinese medicine were divided into the control group and the observation group, 33 cases in each group. The control group were injected with saline 2 mL and the observation group were received dexamethasone 10mg by intravenous infusion. The incidence of complications and complications were observed in the two groups at different times after treatment. Results At 1 hours, 4 hours, 12 hours and 24 hours after extubation, the differencesof the incidence of sore throat and throat pain degree between the two groups was not statistically significant. Conclusion Dexamethasone intravenous administration has no obvious effect on reducing airway complications after laparoscopic cholecystectomy.

Objective To study and analyze the effect of small dose dexamethasone on the prevention of throat pain at perioperative period of thyroid tumor resection. Methods 112 cases with thyroid cancer treated by resection in Wenling hospital of traditional Chinese medicine from July 2014 to July 2016 were selected as the study subjects which were divided into the study and the control group. The control group were given saline by intravenous injection, The study group were given small dose of dexamethasone intravenous injection. The preventive effect of postoperative throat pain and postoperative blood glucose level were compared between the two groups. Results Statistical analysis showed that the postoperative VAS score in the study group was better than that in the control group. The blood glucose level in the study group was better than that in the control group, the difference was statistically significant (P<0.05). Conclusion Perioperative treatment with small doses of dexamethasone is excellent for patients with thyroid tumors treated with resection. It can help patients prevent postoperative sore throat and has excellent application value and is worthy of clinical promotion.

Objective T_O analyze the electrophysiological features of shoulder-hand syndrome(SHS)fol- lowing stroke and investigate the relationships between peripheral nerve damage and the factors causing SHS.Meth- ods Fifty-eight stroke patients were divided into an SHS group(39 patients with shoulder-hand syndrome)and a model group(19 patients without shoulder-hand syndrome).Standard sensory and motor nerve conduction studies were performed with 58 of the patients,including sensory nerve conduction velocity(SCV),amplitude of the sensory nerve action potential(SNAP),distal motor latency(DMI)and the amplitude of the compound muscle action poten- tial(CMAP)of the median nerve.A needle electromyogram(EMG)test was performed on the abductor pollicis of the affected side with both groups.Results The needle EMG showed abnormal insertion potential,fibrillation po- tential and positive sharp waves in all 39 cases of the SHS group,which was significantly higher than in the model group.The amplitude of the sensory nerve action potential(7.77?4.34 mV)and the amplitude of the compound muscle action potential(10.13?3.15 mV)were significantly lower than those of the model group.Abnormal ampli- tude was more severe in sensory nerves than in motor nerves.Conclusion Peripheral nerve damage was found in the shoulder-hand syndrome patients,and this damage was mainly the dystrophy of axonal neuropathy.The damage severity was more in sensory nerves than in motor nerves.The study could offer an useful clue of prevention and treat- ment of shoulder-hand syndrome.

Objective:To introduce a modified method for umbilical reconstruction after single-incision laparoscopic surgery.Methods:Between June 2012 and June 2015,173 patients underwent single-incision laparoscopic cholecystectomy at our institution.All the patients adopted our modified method for umbilical reconstruction.Results:All the surgeries were successful.The umbilical incision healed well with good cosmetic result.Conclusion:The modified method for umbilical reconstruction can improve cosmesis and decrease the possibility of incision hernia after single-incision laparoscopic surgery.More studies are needed to evaluate definitive clinical advantages of this technique.

Objective To investigate the effect of radiotherapy on carotid plaque ulcer formation by using ultrasound imaging.Methods Totally 93 cases diagnosed with head and neck cancers which had complete carotid ultrasound data and other baseline data before and after radiotherapy (RT) were retrospectively enrolled.The total number of plaques,average intima-media thickness,maximum plaque area,total number of ulcer plaques,maximum ulcer plaque area and the maximum area of the ulcer pit were compared in RT side and non RT side before and after RT respectively.Results The average interval time was 6.1±1.9 years between twice RT.Before RT,there were no statistical differences between RT side and non-RT side in the total number of plaques,the average intima-media thickness,maximum plaque area,total number of ulcer plaques,maximum ulcer plaque area and maximum area of the ulcer pit.After RT,compared with those of non-RT side,there were more lesions of the total number of plaques,the thicker average intima-media thickness,the larger maximum plaque area,the more maximum number of ulcer plaques,the larger maximum ulcer plaque area and maximum area of the ulcer pit in RT side,which had statistical defference (all P＜0.05).Conclusion RT can lead to the formation and progression of carotid atherosclerotic plaque in patients with head and neck cancers,and the plaque has a vulnerability characteristics.

Aim To explore the role of endoplasmic reticulum stress (EPR) in high fatty acid induced injury in cardiomyocytes.Methods Cardiomyocytes were exposed to different concentrations of palmitic acid (0, 0.1, 0.2, 0.4 mmol·L-1) for 24 h and different time points of high palmitic acid (0.2 mmol·L-1) (12, 24, 48 h).Cell viability was measured by CCK8, and the protein expressions of EPR such as GRP78, CHOP, PERKphos, IRE1phos, ATF6 and apoptosis related proteins such as Bcl-2 and Bax were determined by Western blot.Results When the cells were stimulated with palmitic acid (0.1~0.4 mmol·L-1) for 24 h, the cell proliferation rates of 0.2 and 0.4 mmol·L-1 groups were significantly decreased.Cardiomyocytes exposured to high palmitic acid (0.2 mmol·L-1) for 24 h showed an increase in theexpression of EPR related proteins (GRP78, CHOP, PERKphos, IRE1phos and ATF6) and Bax(P<0.05), while Bcl-2 expression was significantly reduced.Pretreatmented with EPR inhibitor pravastatin(10 mol·L-1) significantly increased high palmitic acid induced Bcl-2 expression (P<0.05) and significantly decreased high palmitic acid induced Bax expression (P<0.05).Conclusion Activated EPR might play an important role in treatment of high fatty acid induced myocardial injury.

Objective To investigate the neurosurgery nurses turnover intention and the psychological contract status to analyze the relationship between them. Methods The Departure Will Scale and Questionnaire of Psychological Contract were used to survey 128 neurosurgery nurses from seven general hospitals in Lishui city. Results Of neurosurgery nurses turnover intention scale was (2.24±0.71) points, whose leaving intend was stronger;Psychological contract items was (4.17±0.67) points, which organization responsibility score wasbelow employees responsibility; Hierarchical regression analysis showed that the psychological contract in the organization responsibility (organization specification responsibility, organization, personal responsibility and organizational development responsibility) could predict neurosurgery nurses′ willingness to leave, which could be able to explain their willingness to leave 13.5%of the variation. Conclusions Neurosurgery nurses′willingness to leave is strong, and psychological contract is an important factors affecting the will of their departure.

Objective To discuss and validate which method is more effectiveness for central placenta previa through analysing the clinical outcomes of the management of hemorrhage between uterine packing and stitching hemo-stasis during cesarean section.Methods 48 pregnant women with central placenta previa was conducted in this ret-rospective study,which were all cesarean section delivery.These patients were divided into two groups.24 patients with uterine packing with gauze in the control of massive hemorrhage during cesarean section were indetified,other-wise,the other 24 patients were conducted with sewing and ligation uterine.And then,the effectiveness and outcomes were compared.Results These all patients were alive and keep the uterus.The average estimated blood loss of the stiching group was (554 ±327)mL,obviously less than the uterine packing group,which was (828 ±584)mL,and the difference was statisatically significant (t =6.689,P<0.01 ).The rate of blood transfusion during operation was 8.33% (2/24)in the group of stiching,and was 50.0%(12/24)in the uterine packing group(P<0.05).Similar-ly,the operation time of the stiching hemostasis group,which was (48.9 ±10.0)min,was evidently shorter than (68.3 ±13.3)min of the other group(t=8.126,P<0.01).The two groups had no significant difference in therate of primary healing of incision,postoperative fever and admission time(P>0.05).Conclusion The uterine stiching is an effective,rapid and simple technique in the control of hemorrhage of central placenta previa.

Objective To investigate the high risk factors of chlamydia (CT) infection in female.Methods Enzyme linked immunosorbent assay was used to detect 120 cases of gynecological clinic,including 60 cases asymptomatic patients before abortion and 60 cases patients with symptoms of mild genital itching,vaginal secretions slight increased.CT antigen in uterine cervix were detected,and the relationship between its symptoms,age,birth time,contraception,cervical condition,the number of sexual partners,mycoplasma and CT infection were analyzed.Results Among 120 cases,there were 28 cases of CT positive,positive rate was 23.3％ (28/120).CT infection rate of symptomatic and asymptomatic patients was 16.7％,30.0％ respectively,the difference was not significant(P＞0.05).The CT infection rate of patients' age younger than 30 years was 27.8％,higher than older than 30 years (10.0％),the difference was significant(x2=3.975,P＞0.05).The CT infection rate of patients had multiple sexual partners in nearly lyear was 62.5％,higher than that had one sexual partner(9.0％),the difference was significant(x2=37.42,P＞0.05).The CT infection rate of patients didn't use contraceptive tools was 29.1％,higher than that used contraceptive tools(12.2％),the difference was significant(x2=4.319,P＜0.05).Conclusion The symptoms of CT infection are no specificity,should be targeted at screening for patients have high-risk factors,such as age less than 30 years old,have multiple sexual partners nearly 1 year and don' t use contraceptive tools.
