Objective To evaluate the safety and feasibility of single-port laparoscopic surgery (SPLS) for chronic appendicitis.Methods Data of patients who had undergone either conventional threeport surgery (n =58) or SPLS (n =63) for chronic appendicitis between January 2010 and November 2012 were analyzed retrospectively.The short-term outcomes of these 2 operative modalities were compared.Results The overall satisfaction score of SPLS group was significantly higher than that of the three-port group (4.5 ±0.7) vs.(3.0 ±0.6),t =13.50,P =0.00,there was less frequent use of parenteral narcotics in SPLS patients (1.2 ± 0.5) vs.(2.1 ± 0.7) times,t =-8.25,P =0.00,length of operation time was the same in SPLS group (40 ± 10) vs.(37 ±9) minutes,t =1.94,P =0.055.There was not different in postoperative recovery (1.4 ± 0.6) vs.(1.6 ± 0.7) d,t =-1.82,P =0.072,nor different in perioperative complications and intraoperative blood loss between groups (12 ± 6) vs.(13 ± 6) ml,t =-1.50,P =0.137.Conclusions SPLS is both safe and feasible in the treatment of chronic appendicitis.

Objective To study the protective effects of taurine on liver and kidney injury induced by intestinal ischemia-reperfusion(I/R) in rats.Methods Male Wistar rats were randomly assigned into Sham,I/R,and taurine groups.Thirty min before operation,2% taurine(200 mg/kg) was injected via dorsal vein of the rat′s penis.Intestinal ischemia-reperfusion was produced by occlusion of superior mesenteric artery for one hour later,then the blood flow was restored by removing the clamps.Blood samples were taken from rats in I/R and taurine groups at 1.5,3,6 and 12h after reperfusion,and the serum levels of ALT,AST,BUN and Cr were measured to evaluate the functions of liver and kidney.Tissues from livers and kidneys were cryostated and stained with hematoxylin and eosin to observe changes in histological pathology.TUNEL was also performed to examine apoptotic cells and the average light density levels were measured.Results The serum levels of ALT,AST,BUN and Cr in I/R group were significantly higher than those in Sham group(P

Objective:To explore the value of transapical catheter of mitral valve repair (MVR) with Memoclip device in the management of moderate to severe and severe mitral regurgitation (MR) guided by transesophageal echocardiography (TEE).Methods:Fifteen patients with moderate to severe and severe MR in Hefei High-tech Cardiovascular Hospital from December 2021 to October 2022 were prospectively selected. Mitral valve morphology and length, regurgitation severity, left ventricular ejection fraction and pulmonary venous Doppler spectra were carefully evaluated before MVR by TEE.Intraprocedural TEE was performed to guide the MVR including transseptal catheterization, alignment of the clip delivery system, assessment of leaflet capture, clip deployment, post-clip deployment assessment, and withdrawal of the clip delivery system. The position and coaptation length of the clips, the mitral orifice morphology, residual mitral valve regurgitation and pressure gradient were evaluated after MVR.Meanwhile, the complications were monitored throughout the procedure.Results:Among the 15 patients, 12 were implanted with 1 clip and 3 were implanted with 2 clips, respectively. No complications occurred. There were 13 patients with mild regurgitation and 2 showed to moderate mitral regurgitation 1 month later after MVR, and 13 remained mild and 2 maintained moderate regurgitation 3 months later. Significant differences were found in maximal MR area (MRA-max), maximal and mean mitral valve pressure gradient (MVPG-max, MVPG-mean) and mitral valve area (MVA) among the 5 observation time points (all P<0.05). MRA-max, MVA and MVPG-mean were significantly decreased immediately and 3 months after the procedure ( P<0.001). No significant stenosis was found in mitral valve after MVR. Conclusions:MVR with Memoclip is safe, effective, easy to operate in treating patients with moderate to severe and severe MR. TEE plays a key role in perioperative MVR with Memoclip through apical catheterization.

ObjectiveTo explore the beliefs and attitudes about sleep in patients with comorbid depressive disorder and insomnia， and to explore its influence on sleep quality. MethodsPatients with comorbid depressive disorder and insomnia （n=61） and patients with primary insomnia （n=62） who met criteria specified in the Diagnostic and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） in Beijing Anding Hospital Affiliated to Capital Medical University were enrolled， meantime， another 64 healthy controls were recruited. All subjects were assessed using Dysfunctional Beliefs and Attitudes about Sleep （DBAS） and Pittsburgh Sleep Quality Index （PSQI）. Additionally， patients with comorbid depressive disorder and insomnia were evaluated using Hamilton Depression Scale-17 item （HAMD-17）. The PSQI and DBAS scores were compared among three groups using analysis of covariance， and multiple linear regression analysis was used to screen the factors affecting PSQI score in patients with comorbid depressive disorder and insomnia. ResultsCompared with healthy controls， higher scores of PSQI （t=18.932， 18.610， P<0.01） along with lower scores of DBAS （t=-5.561， -5.791， P<0.01） were observed in patients with comorbid depressive disorder and insomnia and patients with primary insomnia. Taking the PSQI score of patients with comorbid depressive disorder and insomnia as the dependent variable， statistically significant equations were generated using multiple linear regression analysis （F=14.095， R²=0.327， P<0.05）， and the predictive and control factors of sleep in DBAS and age were found to be the influencing factors of PSQI score in patients （B=-0.100， -0.279， P<0.05 or 0.01）. ConclusionCompared with the normal，depression patients with insomnia have more dysfunctional beliefs and attitudes towards sleep，and dysfunctional cognition may be the influencing factor of their sleep quality.

ObjectiveTo study the prevalence of depression and the related influencing factors among the frontline healthcare professionals in the prevention and control of risk of imported COVID-19 cases， so as to provide references for improving their mental health status. MethodsBased on Wenjuanxing platform， a total of 984 frontline healthcare professionals participating in the screening and treatment of imported COVID-19 cases in Beijing Xiaotangshan hospital were assessed using Patients’ Health Questionnaire Depression Scale-9 item（PHQ-9）. ResultsA total of 770 questionnaires were collected with a valid rate of 78.3%， among which 344 cases （44.7%） had depressive symptoms. Logistic regression analysis showed that great changes in work content （OR=2.206， P<0.01）， sleep deprivation （OR=2.359， P<0.01）， six hours or less of sleep （OR=2.032， P<0.05）， focusing on epidemic information more than 1 hour per day （OR=1.095， P<0.05） were risk factors for depression， and regular exercise （OR=0.473， P<0.01） was a protective factor for depression relief. ConclusionThe frontline healthcare professionals in the prevention and control of risk of imported COVID-19 cases suffer a high risk of depression， while measures including scientific shift system， adequate sleep， less attention to the epidemic， and regular exercise may be effective in maintaining their physical and mental health.

OBJECTIVETo explore the primary site and pathological feature of neuroendocrine neoplasm (NEN), especially the NEN of digestive system.

METHODSClinicopathological data of NEN patients at China-Japan Friendship Hospital from January 2012 to December 2016 were retrospectively analyzed. Tumor primary sites were summarized. Association between tumor site and pathological grading in gastroenteropancreatic neuroendocrine neoplasm(GEP-NEN) was examined.

RESULTSThere were a total of 903 cases of NEN. Sites of primary tumor included the digestive system in 699 cases(77.4%), the thorax(including lung, thymus and mediastinum) in 87 cases(9.6%), other sites in 60 cases (6.6%), unknown in 57 cases(6.3%). Among 699 GEP-NEN cases, the primary sites included the stomachin in 207 cases (29.6%), pancreas in 201 (28.8%), rectumin in 185 (26.5%), duodenum in 43(6.2%), jejunum and ileum in 18(2.6%), appendix in 15 (2.1%), gallbladder in 11(1.6%), esophagus in 10(1.4%), and the colon in 9 cases (1.3%). Pathologically, the tumor grading was neuroendocrine tumor (NET) G1 in 336 cases(48.1%), NET G2 in 203 cases (29.0%), neuroendocrine carcinoma (NEC) G3 in 139 cases (19.9%). All the esophagus NEN(10/10), most gallbladder NEN(9/11) and colon NEN(6/9) were poorly-differentiated NEC (G3), while all appendix NEN(15/15), most stomach NEN(147/207, 71.0%), pancreas NEN (156/201, 77.6%), rectum NEN (169/185, 91.4%), duodenum NEN (31/43, 72.1%), jejunum and ileum NEN(16/18, 88.9%) were well-differentiated NET G1 or G2.

CONCLUSIONSThe most common primary site of NEN is the digestive system. The stomach, pancreas and rectum are most common primary sitesof GEP-NEN. Difference in pathological grading is quite greatin different primary sites of GEP-NEN. Most NENs fromesophagus, colon and gallbladder are poorly-differentiated NEC.
