Objective:To analyze the interim clinical efficacy of laparoscopic and open distal gastrectomy for gastric cancer in elderly patients.Methods:The prospective randomized controlled study was conducted. The clinicopathological data of 102 patients aged ≥65 years who underwent distal gastrectomy for gastric cancer in the Nanfang Hospital of Southern Medical University from September 2014 to May 2018 were collected. After excluding 6 patients, 96 patients were finally included. Based on random number table, patients were allocated into two groups. Patients undergoing laparoscopic distal gastrectomy were allocated into laparoscopic group, and patients undergoing open distal gastrectomy were allocated into open group, respectively. Obser-vation indicators: (1) grouping situations of the enrolled patients; (2) intraoperative situations; (3) postoperative situations; (4) follow-up. Follow-up using outpatient examination and telephone interview was conducted to detect complications in the postoperative 30 days up to July 2018. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M( P25, P75) or M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Comparison of ordinal data was analyzed using the non-parameter Mann-Whitney U test. Results:(1) Grouping situations of the enrolled patients: a total of 96 patients were selected for eligibility. There were 66 males and 30 females, aged from 65 to 85 years, with a median age of 69 years. There were 49 of 96 patients in the laparoscopic group and 47 patients in the open group. (2) Intraoperative situations: patients in the two groups underwent distal gastrectomy successfully with D 2 lymphadenectomy, without intra-operative conversion to laparotomy. The volume of intraoperative blood loss and surgical incision length were 50 mL(50 mL,100 mL) and (7.1±1.7)cm for the laparoscopic group, respectively, versus 100 mL(100 mL,200 mL) and (19.1±1.7)cm for the open group, showing significant differences between the two groups ( Z=?3.779, t=?34.880, P<0.05) . (3) Postoperative situations: the number of lymph node dissected, time to postoperative initial out-of-bed activities, time to postoperative first flatus, time to postoperative first liquid food intake, time to postoperative first semi-liquid food intake, time to drainage tube removal, duration of postoperative hospital stay were 49(35,62), 1.9 days(1.3 days,2.9 days), 2.6 days(2.2 days,2.9 days), 3.4 days(2.7days,4.0 days), 5.9 days(4.7 days,7.7 days), 4.9 days(3.5 days,6.8 days), 7.7 days(6.7 days,8.9 days) for the laparoscopic group, respectively, versus 40(27,51), 2.5 days (1.8 days,3.3 days), 2.6 days(2.2 days,2.9 days), 3.9 days(2.9 days,5.7 days), 4.9 days(3.9 days, 5.9 days), 6.3 days(4.7 days,8.9 days), 8.7 days(6.9 days,11.7 days), showing significant differences between the two groups ( Z=?2.354, ?2.210, ?2.743, ?2.474, ?2.906, ?2.503, ?2.359, P<0.05). (4) Follow-up: patients in the two groups received 30 days of follow-up. During the follow-up, 8 patients in the laparoscopic group had postoperative complications, including 1 case with Clavien-Dindo grade Ⅰ complications, 7 cases with Clavien-Dindo grade Ⅱ complications, and no patient with Clavien-Dindo grade Ⅲ complications. Thirteen patients in the open group had postoperative complications, including 2 cases with Clavien-Dindo grade Ⅰ complications, 10 cases with Clavien-Dindo grade Ⅱ complications, and 1 case with Clavien-Dindo grade Ⅲ complications. There was no significant difference in the above indicators between the two groups ( χ2=1.135, 1.973, 1.054, P>0.05). The overall complication rate was 16.3%(8/49) and 27.7%(13/47) for the laparoscopic group and open group, respectively, showing no significant difference between the two groups ( χ2=1.803, 99.7% confidence interval as ?∞ to 2.4%, P>0.05). The upper limit of 99.7% confidence interval was less than non-inferiority level of 15%, interim analysis of which showed that the complication rate of the laparoscopic group was non-inferior to the open group. Conclusion:For elderly patients undergoing laparoscopic or open distal gastrectomy for gastric cancer, laparoscopic surgery does not increase intraoperative or postoperative complications, and has advantages of minimally invasiveness, fine operation, quicker recovery, and shorter hospital stay. Registry: this study was registered at clinicaltrials.gov in United States, with the registry number of NCT02246153.

OBJECTIVETo study the clinical characteristics and the treatment of periorbital injuries.

METHODS61 cases were treated, including 30 cases orbitozygomatic fracture, 6 cases of frontal-orbital fracture, 8 cases of naso-ethmoid-orbital fracture, 7 cases of blow -out fracture and 10 cases of complicated fracture. The patients were diagnosed after physical examination and other examination, like CT. Through bicoronal or local mini incision at the end of eyebrow, combined with subciliary incision and local wound approach, the fractured sites were exposed completely. Then the fractured fragments were repositioned and fixed rigidly. The orbital wall was reconstructed with titanium net and Medpor.

RESULTSThe wounds healed primarily. Good cosmetic and functional results achieved in most of the patients. 4 cases underwent second-stage ophthalmectomy. 2 patients had diplopia after operation, but improved gradually. 3 cases of blepharoptosis needed further treatment.

CONCLUSIONSEarly diagnosis and treatment is very important for periorbital injuries. Fracture reposition and orbital wall reconstruction should he performed at early period.

Objective: To explore the relationship between handgrip strength (HGS) and pulmonary function (PF) in college students with sedentary lifestyle, so as to provide a reference for taking HGS as an essential factor of PF. Methods: In March 1-5, 2023, a total of 44 college students were recruited and were divided into the sedentary group (22) and exercise group (22) according to the International Physical Activity Questionaire (IPAQ), with 22 students in each group. Independent sample t-test was used to compare the indexes between groups, pearson correlation coefficient was used to determine the correlation between HGS and PF. Multiple linear regression analysis was used to determine the predictive model of PF. Results: There were statistical significance of the correlations between HGS and FVC, MEP, PEF, FEV1, FIVC, MIP, and PIF ( r=0.79, 0.47, 0.44, 0.60, 0.72, 0.53 , 0.49, P <0.01). When gender, physical activity, age, height, weight, and HGS were included as predictors in the regression model, height and HGS had significant effects on FVC ( R 2=0.75, F= 60.55 , P <0.01), weight and HGS had a good predictive effect on FIVC ( R 2=0.67, F=41.77, P <0.01). Conclusion HGS is significantly associated with PF in college students with sedentary lifestyle. Therefore, HGS can be used as an important indicator to predict the PF status of habitual sedentary college students.

Objective To explore the characteristic of fractional amplitude of low frequency fluctuation (fALFF) and the relationship with the severity of depression, suicidal ideation and suicide risk in depression patients with suicidal ideation with resting-state functional magnetic resonance imaging (rs-fMRI). Methods Resting state functional magnetic resonance imaging maps were conducted using fractional amplitude of low frequency fluctuation (fALFF) in 52 depression patients (30 with suicidal ideation and 22 without) and 21 healthy controls (HCs). The severity of depression was evaluat-ed by using Hamilton Depression scale(HAMD). The suicidal ideation, the suicide risk in depression patients with sui-cidal ideation were both assessed by the Beck Scale for Suicide Ideation. The correlation between the fALFF value and the score of HAMD and the Beck Scale for Suicide Ideation was analyzed. Results MRI revealed significant differences in fALFF in the left superior/middle occipital gyrus and the right middle/inferior occipital gyrus (P<0.05, AlphaSim cor-rected)between depression patients with suicidal ideation and the HCs. Compared to the HCs, depression patients with-out suicidal ideation showed a higher fALFF in the left middle occipital gyrus (P<0.05, AlphaSim corrected). MRI re-vealed significant differences in fALFF in the left middle occipital gyrus (P<0.01, AlphaSim corrected)and the right mid-dle occipital gyrus (P<0.01, AlphaSim corrected) between depression patients with suicidal ideation and without. The fALFF of left middle occipital gyrus (r=0.366, P=0.046) and right middle occipital gyrus (r=0.513, P=0.004) were posi-tively correlated with the scores of HAMD, respectively whereas were not correlated with suicidal ideation and suicide risk. Conclusions Depression patients with suicidal ideation have an abnormal spontaneous activity in their left and right middle occipital gyrus. The increased activity in these brain areas are probably associated with the severity of de-pression whereas are not associated with suicidal ideation or suicide risk.

Objective To summarize the experience ofmultidisciplinary team (MDT) in diagnosis and treatment of complicated and refractory thyroid tumors.Methods A retrospective review was performed on clinical data of 46 cases with complicated and refractory large thyroid tumors admitted to our hospital from Jan.2010 to Dec.2016.There were 23 cases in MDT group and 23 cases in the control group,respectively.The MDT group received diagnosis and treatment provided by multidisciplinary team during perioperative period whereas the control group received conventional surgery.Results Short-term complications such as trouble breathing and thyroid crisis were not observed in 46 patients after surgery.In the control group,the mean durations were (52±11.5)minutes for anesthesia,(159±38.1) minutes for surgery and (11 ±3.5) days for hospital stay,respectively.After surgery,bleeding occurred in 5 cases,hoarseness in 5 cases,irritating cough when drinking in 7 cases,transient hypocalcemia in 8 cases,permanent hypocalcemia in 6 cases,and neck tracheotomy due to tracheomalacia during surgery in 2 cases.In MDT group,the mean durations were (37±8.5) minutes for anesthesia,(134±28.5) minutes for surgery and (7±1.5) days,respectively.After surgery,bleeding occurred in 0 case,hoarseness in 0 case,irritating cough when drinking in 1 case,transient hypocalcemia in 2 cases,permanent hypocalcemia in 0 case,and neck tracheotomy due to tracheomalacia during surgery in 4 cases.Conclusion Application of multidisciplinary team in diagnosis and treatment of complicated and refractory thyroid tumors can reduce duration of preoperative endotracheal anesthesia as well as surgery,decrease postoperative complications,shorten duration of hospitalization and improve life quality after surgery.

Objective To evaluate the efficacy of Disposcope endoscope(DE)-guided nasotrache-al intubation in patients with difficult airway by comparing with fiberoptic bronchoscope(FOB). Methods One hundred and twenty American Society of Anesthesiologists physical statusⅠ-Ⅲ patients of both se-xes, with body mass index<25 kg∕m2, aged 18-64 yr, with mouth opening<3 cm, of Mallampati classifi-cation Ⅲ or Ⅳ, undergoing maxillofacial surgery requiring nasotracheal intubation were divided into DE group(n=60)and FOB group(n=60)using a random number table.Nasotracheal intubation was per-formed under the guidance of DE or FOB after induction of anesthesia.Glottis exposure was evaluated using Cormack-Lehane grade.Epistaxis during intubation, successful intubation, time and degree of glottis expo-sure, intubation time and development of tachycardia and hypertension and requirement for assisted ventila-tion with face mask during intubation were recorded.The patients were followed up postoperatively, and the development of intubation-related complications was also recorded.Results Compared with group FOB, glottis exposure time and incubation time were significantly shortened(P<0.05), and no significant change was found in Cormack-Lehane grade, rate of successful incubation, rate of successful intubation at first attempt or intubation-related complications in group DE(P>0.05). Hypertension and tachycardia were not found and no patients required assisted ventilation with face mask during intubation in the two groups.Conclusion DE-guided nasotracheal intubation provides similar efficacy to that of FOB with shorter time and is an optimal selection for the patients with difficult airway.
