Objective:This study aimed to examine the prevalence of comorbid generalized anxiety disorder (GAD) among adult patients with major depressive disorder (MDD) in China and explore its potential risk factors.Methods:This is a multicenter, cross-sectional study, involving 1 086 patients in 9 clinical settings. The diagnosis of MDD and GAD were confirmed by the MINI. Life events were evaluated by the Life Events Scale (LES), and early life stress was assessed by the Childhood Trauma Questionnaire (CTQ). The severity of depression, social support, coping style and personality traits were assessed by Hamilton Depression Rating Scale-17 item (HAMD 17), Simplified Coping Style Questionnaire (SCSQ), and Eysenck Personality Questionnaire, short scale for China (EPQ-RSC), respectively. Pearson correlation analysis, univariate regression analysis and Logistic regression analysis were used to explore the association of clinical characteristics, life stress, social factors and comorbidity of MDD and GAD. Results:Among 1 086 MDD patients, 276 of them (25.4%) were diagnosed with comorbid GAD. Patients with comorbid GAD were more likely to report adulthood adversity then those without (60.2% （165/276） vs. 39.9%（321/810）, χ2=33.993， P<0.01). However, there was no difference in social support and coping styles between the two groups. Furthermore, patients with comorbid GAD had higher levels of neuroticism, and lower levels of extraversion. After controlling for confounders, logistic regression results showed that adulthood adversity ( OR=1.720, 95% CI 1.262-2.343, P<0.01) and higher neuroticism levels (O R=1.211, 95% CI 1.141-1.286, P<0.01) were significantly associated with comorbid GAD in patients with MDD. Conclusion:Adulthood adversity and high levels of neuroticism were potential risk factors of comorbidity of MDD and GAD. This finding provides empirical evidence for developing targeted interventions for this subgroup population with MDD.

This pilot study aimed to investigate the feasibility of trans-oral ultrasonography of the temporomandibular joint (TMJ) in oblique sagittal plane. Six volunteers who were receiving residency training at Hainan Hospital of General Hospital of Chinese PLA were recruited into this study, five of them had normal TMJ and one had anterior displaced disc all of which had been confirmed by MRI. A hockey-stick-shaped ultrasound probe was placed between the cheek and maxilla to push against the mucosa lateral to posterior maxillary tuberosity, and every volunteer underwent bilateral scans. The sonographic imaging were completed successfully on the six volunteers; the condyle, the superior and the inferior head of the lateral pterygoid muscle, the disc and the maxillary vein were clearly identified in all the twelve ultrasonographic scans. The feasibility of trans-oral ultrasonography of TMJ in oblique sagittal plane was confirmed.

Submandibular gland excision was performed on two patients using trans-oral robotic surgery (TORS). Complications such as the injury of marginal mandibular branch of facial nerve, ranula in the floor of the mouth, and postoperative hemorrhage were not observed. Visible cervical scar can be avoided and esthetic outcome can be expected by using this surgical modality.

Objective: To explore the feasibility of using da Vinci Surgical System to perform supraomohyoid neck dissection (SOND) to avoid visible scar and reduce trauma. Methods: Between September 2017 and December 2018, twenty patients (two females and 18 males, mean age, 54.8 years) with oral cancer treated in the Department of Stomatology, Hainan Hospital of General Hospital of Chinese PLA were enrolled in this study. Eight patients were assigned into robotic surgery group, and received robot-assisted SOND with retroauricular hairline incision. After the da Vinci Surgical System robotic platform was positioned, the neck dissection was performed in level Ⅱb, Ⅱa, Ⅲ, Ⅰb and Ⅰa orderly from the near region to far region. The other 12 patients were assigned into traditional surgery group, and received SOND with a traditional incision. The operation time, bleeding and amount of lymph node dissected were compared between two groups. Results: All the 8 cases of robot-assisted SOND were completed smoothly. Operation time [(4.5±1.0) h] was significantly longer in robotic surgery group than that [(2.5±1.0) h] in traditional surgery group (P<0.05). The amount of bleeding in robotic surgery group [30.0 (27.5) ml] was significantly lower than that in traditional surgery group [(100.0 (87.5) ml, P<0.05]. There′s no difference in the number of lymph nodes dissected between robotic surgery group (23.6±5.2) and traditional surgery group (22.8±6.0)(P>0.05). No postoperative hemorrhage, symptoms of nerve injury, flap necrosis and secondary healing were observed in robotic surgery group. Conclusions SOND through retroauricular hairline incision is feasible with the assistance of da Vinci Surgical System. The main advantage of this method is superior esthetic effects due to a hidden incision with minimal bleeding. There was no obvious differences in the amount of lymph nodes dissected and postoperative complications between two methods. However, robotic surgery costs a significantly longer operation time than traditional neck dissection.

Objective To evaluate the effect of ulinastatin (UT1) on the expression of aquaporin 1 (AQP1) and AQP5 in rats with acute lung injury induced by cardiopulmonary bypass (CPB).Methods Forty-eight clean-grade healthy adult male Sprague-Dawley rats,weighing 200-250 g,were divided into 3 groups (n=16 each) using a random number table method:sham operation group (Sham group),CPB group and UTI group.UTI 200 000 U/kg was injected intravenously at 10 min prior to CPB in UTI group.The model of CPB was established in CPB and UTI groups.The equal volume of normal saline was intravenously injected at 10 min prior to puncture or at 10 min prior to CPB in Sham and CPB groups.Rats were sacrificed,and lung tissues were excised for determination of weight to dry weight ratio (W/D ratio),expression of AQP1 and AQP5 (by immunohistochemistry),expression of AQP1 and AQP5 protein and mRNA (by real-time polymerase chain reaction or Western blot) and for examination of morphological structure (with a light microscope) and ultrastructure of lung tissues (with an electron microscope).Injured alveolar rate (IAR) and rates of AQP1 and AQP5 positive cells were calculated.Results Compared with Sham group,W/D ratio and IAR were significantly increased,rates of AQP1 and AQP5 positive ceils were decreased,and the expression of AQP1 and AQP5 protein and mRNA was down-regulated in CPB and UTI groups (P＜0.05).Compared with CPB group,W/D ratio and IAR were significantly decreased,rates of AQP1 and AQP5 positive cells were increased,and the expression of AQP1 and AQP5 protein and mRNA was up-regulated in UTI group (P＜0.05).The injury to morphological structure and ultrastructure was significantly attenuated in UTI group when compared with CPB group.Conclusion The mechanism by which UTI pretreatment reduces CPB-induced acute lung injury is related to up-regulating the expression of AQP1 and AQP5 in rats.

Objective To explore the effect of midazolam on the agitation and wake time of the postoperative resuscitation in pediatric circumcision.Methods Clinical data of 170 cases of pediatric circumcision were retrospectively analyzed.They were divided into control group and observation group according to the anesthesia scheme ,85 cases in each group.The control group was anesthetized with sevoflurane compound ketamine ,and the observation group was given trifluorothane and ketamine combined with midazolam .The effects of the two groups were compared .Results The cardiac rhythm and the central arterial pressure at first 10min of operation in the observation group were (99.64 ±5.97) times/min,(65.81 ±5.63) mmHg,respectively,which in the control group were (122.38 ± 12.54)times/min,(86.49 ±12.35) mmHg,respectively,the differences between the two groups were statistically significant(t=8.749,9.438,all P<0.05).The total amount of ketamine,waking time,pain score,Watcha score, PAED score in the observation group were (42.33 ±5.85)mg,(5.56 ±2.03)min,(2.16 ±1.05)points,(1.65 ± 0.59)points,(5.23 ±1.04) points,respectively,which in the control group were (72.53 ±16.58) mg,(13.29 ± 4.66)min,(4.29 ±2.35) points,(2.84 ±1.46)points,(8.75 ±2.19)points,respectively,the differences between the two groups were statistically significant(t=11.698,8.239,7.763,6.997,8.168,all P<0.05).The incidence rates of respiratory inhibition ,fidgety,nausea and vomiting of the observation group were 1.18％,3.53％,3.53％, respectively,which of the control group were 9.41％,15.29％,16.47％,respectively,the differences between the two groups were statistically significant(χ2 =4.174,3.589,4.281,all P<0.05).Conclusion Application of midazolam in pediatric prepuce intraoperatively has little influence on the vital signs of children ,and can relieve postoperative awaken agitation , reduce the time of awakening and anesthesia complications , and it is worthy of popularizing in clinical application .
