Objective: To understand the situation of neglect of preschool children in the urban area of Xi an under the background of multi child policy, so as to provide a reference for making effective prevention. Methods: In Novmber 2022, according to the multi stage stratified cluster sampling principle, 2 450 parents of children aged 3-6 years were randomly selected from 7 urban areas of Xi an to participate in the questionnaire survey. A questionnaire survey was conducted using the "Neglect Evaluation Norms of 3-6 Years Old (Preschool) Children in Urban Areas of China". SPSS 18.0 software was used for statistical description, Chi square test and variance analysis. Results: The total neglect rate of preschool children in the urban area of Xi an was 29.0% and the total neglect score was (37.58±8.44). There was no statistical difference in the neglect status of children in different grade groups ( χ 2/ F =1.61, 2.98, P >0.05). The neglect score of boys was higher than girls ( t =2.45, P <0.05). There was no statistical difference in the neglect rate and neglect score of boys and girls in other levels ( P >0.05); except for the significant difference in the neglect degree of medical treatment, education and safety ( t =2.01, 2.28, 2.02, P <0.05). The rate and score of neglect in multi-child families were higher than only-child families ( χ 2/ t = 13.68, -4.54, P <0.05). There were significant differences in the rate and degree of neglect of children with different birth order, which were "third and fourth-born>second-born>first-born" ( χ 2/ F = 10.84 , 2.79, P <0.05). The neglect rate and score of "single parent family" were significantly higher than that of "nuclear family" and "three-generation family" ( χ 2/ F =4.78, 2.79, P <0.05). Conclusion The neglect situation of preschool children in urban area of Xi an is still serious, especially in multi-child families. It should actively explore the risk factors and formulate effective intervention measures.

ObjectiveTo compare the safety and efficacy of penehyclidine hydrochloride （PHC） and atropine in modified electroconvulsive therapy （MECT） under general anesthesia， and to provide a reference for clinical preoperative medication of MECT. MethodsA total of 104 patients treated with MECT were randomly divided into observation group and control group， with 52 cases in each group. The observation group was given PHC， the control group was given atropine before operation and other anesthesia methods were the same. The changes of hemodynamic indexes， the content of oral secretions and the occurrence of adverse reactions within 48 hours after electrotherapy were observed， monitored and recorded. ResultsSystolic blood pressure （SBP）， diastolic blood pressure （DBP）， mean arterial pressure （map） and heart rate （HR） of the two groups increased significantly after electrical stimulation （P<0.05）. There was no significant difference in hemodynamic indexes before and after drug injection in PHC group （P> 0.05）， and the HR increased significantly after drug injection in atropine group （P< 0.05）. The HR of atropine group after drug injection and electrical stimulation was significantly higher than that of PHC group （P< 0.05）， and there was no significant difference in blood pressure， the content of oral secretions and the occurrence of adverse reactions between the two groups （P > 0.05）. ConclusionCompared with atropine， the application of PHC in MECT has higher safety index， better effect of stabilizing hemodynamic indexes， and can be generalized clinically.

Objective: To explore the promotion effect of laparoscopic standardized surgery for gastric cancer observational in some regional medical centers in Shanghai. Methods: A retrospective cohort study was carried out. Eleven regional medical centers in Shanghai received the promotion program of laparoscopic standardized surgery for gastric cancer, which was led by Ruijin Hospital, Shanghai Jiaotong University School of Medicine (Shanghai Minimally Invasive Surgery Center) from January to December 2020. Clinicopathological data of gastric cancer patients treated at these 11 regional medical centers before and after the promotion program were collected. Inclusion criteria were as follows: patients undergoing laparoscopic distal gastrectomy or total gastrectomy; gastric cancer confirmed by pathology; without distant metastasis or peritoneal metastasis. Patients who did not undergo laparoscopic D2 radical resection, or received neoadjuvant chemotherapy before surgery, or without complete clinical data were excluded. Patients undergoing laparoscopic surgery from January to December 2019 were included in the pre-promotion group (46 cases). Patients undergoing laparoscopic surgery from January to December 2021 were included in the post-promotion group (102 cases). In addition, patients undergoing laparoscopic surgery at Ruijin Hospital from January 2021 to December were included in the control group (138 cases). The baseline data, perioperative measurements postoperative complications, and pathological results of the three groups were analyzed and compared. Results: There were no significant differences in baseline characteristics among the three groups (all P>0.05). Compared with the pre-promotion group, the operation time in post-promotion group was significantly shorter [(207.3±36.0) minutes vs. (254.2±47.1) minutes, t=7.038,P<0.001], and the number of harvested lymph node was significantly more (24.4±12.2 vs. 18.9±5.5, t=2.900, P=0.004). However, there were no significant differences in the extent of resection, time to fluid intake, and postoperative hospital stay between the two groups (all P>0.05). Compared with the control group, the operation time [(207.3±36.0) minutes vs (172.6±26.0) minutes, t=8.281, P<0.001], time to fluid intake [(6.3±3.2) days than (5.5±3.0) days, t=2.029, P=0.044], and the postoperative hospital stay [(14.3±5.6) days vs. (10.1±4.8) days, t=6.036, P<0.001] in the post- promotion group were still longer. Total gastrectomy was less common in the post-promotion group compared with the control group [18 cases (17.6%) vs. 41 cases (29.7%), χ²=7.380, P=0.007]. However, there was no significant difference in the number of harvested lymph node between the two groups (P>0.05). The morbidity of postoperative complication in the post-promotion group (9.8%, 10/102) was significantly lower than that in the pre-promotion group (23.9%, 11/46) (χ²=5.183, P=0.023), while above morbidity was not significantly different between the post-promotion group and the control group [9.8% vs. 6.5% (9/138), χ²=0.867, P=0.352]. Conclusion: After the promotion of laparoscopic standardized surgery for gastric cancer in regional medical centers, the standardization degree of surgery has been improved, and the morbidity of postoperative complication decreases. Laparoscopic standardized surgery for gastric cancer can be promoted to more regional medical centers.

Objective: To investigate the impact of surgical treatment on quality of life in patients with locally recurrent rectal cancer (LRRC). Methods: A descriptive case series study was performed. The complete clinical data of 62 patients who met the diagnostic criteria of LRRC and treated by surgical procedures in Huashan Hospital of Fudan University from January 2012 to November 2019 were analyzed retrospectively. All the patients were followed up at least 12 months. Assessments of urinary function, sexual function, mobility function of lower limb and quality of life were documented. Patients with distant metastasis and surgical history of the urinary system were excluded. According to the criteria of Memorial Sloan Kettering Cancer Center (MSKCC), recurrence were divided into central (n=27), anterior (n=20), posterior (n=7), and lateral (n=8) subtypes. Baseline characteristics, surgical procedures and short-term complications were analyzed. International prostate symptom score (IPSS) and grade of voiding dysfunction were used to evaluate the urinary function. Higher score of IPSS and higher grade of voiding dysfunction indicated worse voiding function. Sexual function for both genders was assessed preoperatively and postoperatively. International index of erectile function-5 (IIEF-5) was used for assessment of male patients and higher score indicated better function. Female sexual function index (FSFI) was used in females and higher score indicated better function. Short-form health survey with 36 items (SF-36), yielding an 8-scale profile of functional health (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, emotional health and mental health) was used to evaluate the quality of life. The higher score indicated the better quality of life. Results: All the operations of 62 patients completed successfully and R0 resection rate was 88.7% (55/62). Postoperative surgical complications occurred in 16 cases (25.8%), including 3 patients of Clavien-Dindo classification III. At postoperative 3-month, 42 patients without ileum cystectomy or ureterostomy suffered from different grade of voiding dysfunction. IPSS increased significantly after the surgery (before surgery: 12.36±4.75, after surgery: 18.40±4.77, t=-9.128, P<0.001). There was no significant difference among the subtypes (P>0.05). At postoperative 12-month, IIEF-5 decreased from 14 (0~25) to 9 (0~19) in males (Z=-5.174, P<0.001) and FSFI deceased from 8.4 (2.0-27.0) to 2.0 (2.0-18.4) in females (Z=-3.522, P<0.001). Scores of physical functioning and role-physical decreased significantly [physical functioning: before surgery 70 (35-85), after surgery 65 (30-80), Z=-3.685, P<0.001; role-physical: before surgery 50 (0-50), after surgery 25(0-75), Z=-4.065, P<0.001], while those of social functioning role-emotional and mental health increased significantly after the surgery [social functioning: before surgery 44 (22-78), after surgery 56 (0-89), Z=-3.509, P<0.001; role-emotional: before surgery 17 (0-100), after surgery 33 (0-100), Z=-2.439, P=0.015; mental health: before surgery 40 (36-76), after surgery 52 (24-80), Z=-3.395, P<0.001]. All surgical procedures decreased the voiding function of LRRC patients and the sexual function of male patients (all P<0.01). However, only total pelvic exenteration and posterior pelvic exenteration decreased FSFI in female patients [before surgery: 8.4 (2.0-27.0) after surgery: 2.0 (2.0-18.4), Z=-2.810, P=0.005]. Conclusions: Multi-visceral resection in LRRC patients may damage voiding and sexual function. However, successful and effective surgical treatment can improve the psychosocial health of LRRC patients.

OBJECTIVETo investigate device implanted complications and corresponding therapeutic strategies of Coflex interspinous dynamic stabilization system for lumbar spine intraoperatively and postoperatively.

METHODSFrom September 2008 to August 2010, 133 cases of degenerative disease of lumbar spine including 62 males and 71 females, ranging from 35 to 81 years of age (mean 60.8 years), underwent or planed to be underwent decompression with Coflex interspinous dynamic stabilization system were reviewed retrospectively, and 13 cases including 6 males and 7 females, ranging from 41 to 71 years of age (mean 58.6 years), occurred device implanted complications. The Coflex implanted complications were analyzed, and therapeutic strategies according to different character were carried out, scores of visual analogue scale (VAS), Oswestry disability index(ODI) and effect-related data preoperatively, postoperatively, after conservative treatment and in final follow-up were evaluated with paired-samples t test.

RESULTSThirteen cases of Coflex implanted complications and treatment applied included: 3 cases occurred fracture of spinous processes intraoperatively were treated by pedicle screws instead; 2 cases occurred fracture of spinous processes postoperatively or during follow-up, including 1 case underwent revision with pedicle screws, another 1 case treated with conservative treatment; 4 cases with degenerative coronal spondylolysis in surgical segments, 1 case with sagittal instability preoperatively, and 1 case with device dislodgment in follow-up all suffered aggravated pain and received conservative treatment; 1 case suffered implanted malposition intraoperatively was underwent internal fixation with pedicle screws instead; at length, 1 case with aggravated pain postoperatively and without definite reason received revision with internal fixation of pedicle screws demolishing the Coflex. The follow-up time of 13 cases ranged from 20 to 38 months (mean 27.6 months); and 7 cases implanted Coflex with aggravated pain of lumbar and lower limb, but the position of device can still maintained, were received conservative treatment, and whose score of VAS and ODI in the final follow-up were 1.9 ± 0.7 and 23.2 ± 3.4, and comparing to 6.1 ± 1.1 and 58.1 ± 3.0 preoperatively, evident improvement was got finally (t = 8.2 and 18.2, P < 0.01). Scores of VAS and ODI of 2 cases with Coflex implanted complications underwent revision with pedicle screws were also improved correspondingly.

CONCLUSIONSCoflex interspinous dynamic stabilization system implanted should be avoided to cases who suffered with osteoporosis, too narrow interspinous space and intervertebral coronal spondylolysis or sagittal instability; and choice of device, depth of implantation and intensity of clumping should be appropriate. For patients with symptom but device still in right position, conservative treatment can be carried out; but for patients subjected to malposition of device, failure of implantation intraoperatively or intolerance to device, revisions and salvages should be underwent with internal fixation of pedicle screws.

OBJECTIVETo observe the curative effects of bone marrow stem cell (BMSC) and peripheral blood stem cell (PBSC) transplantations on the avascular necrosis of femoral head (ANFH).

METHODSTotally 122 ANFH patients (211 coxae) treated by BMSC or PBSC transplantations were enrolled from July 2004 to December 2006. All of them were classed to different stages according to the ARCO. Control group were desired as themselves before and after treatment. The puncture of femoral artery was conducted with digital subtraction angiography (DSA), and the tubes were inserted into medial femoral circumflex artery, lateral femoral circumflex artery and obturator artery with the cell suspensions were gradually poured into the arteries.

RESULTSThe joint pain, joint functions and walking distance of 122 patients were detected for the follow-up. Compared with before treatment, the calibers thickened; vessels increased and blood velocity quickened of femoral head blood-supply artery were observed in 15 patients after 6 months checked by DSA. The reduced areas of femoral head necrosis in 8 patients indicated the new bone formation between 12 and 24 months.

CONCLUSIONSAutologous BMSC and PBSC transplantation results in the new bone formation and improvement of ischemia in areas of femoral head necrosis at 6 months. The change of angiography was observed about 12 to 24 months after cell transplantation. The stem cell transplantation is convenient, safe and effective in the treatment of the ANFH with no adverse reaction, and can be considered as a new therapy of ANFH.
