Objective:To study the effects of group counseling which based on interpersonal activities and aimed at the college students with computer gaming addiction in China.Methods:Seventeen college students with computer game addiction were chosen as the experimental group,and 10 college students from another college were chosen as the control group.The two groups had no difference in the scores of Computer Gaming Addiction Invention(CGAI)and several other scales before group counseling.There were a pre-test and a post-test separately set when the group counseling was started and finished,focused on CGAI and negative emotions and cognitions.Results:In post-test,the score of CGAI in experimental group was significantly lower than that in control group[(92.6±16.7)vs.(105.9±13.0)] and lower than that in pre-test(98.9±16.4)by analysis of covariance(Ps<0.01).The scores of Beck Depression Inventory(BDI),Self-Rating Anxiety Scale(SAS),and the negative cognition of oneself in socical settings in experimental group were also lower than those in control group [(6.4±7.9)vs.(13.5±5.6),(39.7±6.4)vs.(49.9±10.3),(15.1±4.3)vs.(19.9±3.0),Ps<0.01],while the score of Rosenberg Self-Esteem Scale(SES)was higher than that of the control group [(29.3±2.9)vs.(24.6±4.8),P<0.01].Conclusion:Group counseling based on interpersonal activities has obvious effects on the college students with computer gaming addiction.

Objective To explore the experience of emergency operation for patent ductus arteriosus (PDA) in neonates and to assess the therapeutic effect.Methods The clinical data of 31 PDA neonates(15 male,16 female) treated in our department from July 2012 to February 2015 were reviewed retrospectively.Of these cases,28 were preterm infants and 3 were full term infants.Mean gestational age was 30+4 weeks ranging from 26+2 to 39 +3 weeks.Mean birth weight and weight at operation was(1 159.0 ± 729.2) g and (1 522.0 ± 644.5) g,respectively.We operated with left transaxillary straight incision in 6 cases and posterolateral minimal incision in 25 cases,and the pleural cavity was entered via the 4th intercostal space.All the neonates were divided into ＜ 1 500 g group(n =24) and ＞ 1 500 g group(n =7) by weight,the clinical prognosis were analysized.Results All 31 operations were finished successfully.No deaths occurred as a result of surgery.Average time of operation was (62.7 ± 29.9) min.Mean time of mchanical ventilation after the operation among survivors was (5.5 ± 4.7) d.The time of mechanical ventilation between ＜ 1 500 g group and ＞ 1 500 g group were (7.2 ± 2.3) d and (4.9 ± 2.4) d respectively,and there was significant difference between two groups(P ＜ 0.001).The time of hospital stay were (45.3 ± 11.0) d and (20.4 ± 14.5) d respectively between two groups (P ＞ 0.05).Twenty-eight cases recovered and released from the hospital successfully.Two cases quited the treatment themselves and 1 succumbed to death because of heart failure,hyperkalemia and arrhythmia.ConclusionEmergency surgical closure is a safe and effective method for the treatment of neonatal large PDA,especially with congestive heart failure,a variety of complications,long time ventilator dependence,medical treatment failure,which should be ligatured timely as it can have severe influence on the cardiopulmonary function.After ligation the abnormal shunt will disappear and the cardiopulmonary function will be better.It is helpful to extubate ventilators and improve the survival rates.

BACKGROUND: Peripheral nerve injuries are hoped to promote the regeneration of nerve repair by elevating brain-derived neurotrophic factor (BDNF) concentration in local injury regions. OBJECTIVE: To observe the recanalization of nerve fiber and motor function in sciatic nerve injury rats following BDNF gene-modified bone marrow mesenchymal stem cells (BMSCs). DESIGN, TIME AND SETTING: The randomized, controlled animal study was performed at the Fujian Institute of Neurology from May 2007 to May 2008. MATERIALS: Femur and tibia of F344 male rats aged 2 months were sterilely harvested to prepare BMSCs. BDNF gene-modified BMSCs were prepared using constructed chronic viral vector PNL-BDNF-IRES2-EGFP. METHODS: The right sciatic nerve injury models were made using 60 adult Sprague Dawley rats. All models were randomly assigned into phosphate buffer saline (PBS) group, BMSC group and BDNF gene-modified BMSC group. 2 ?L BPS, 2 ?L BMSC solution and 2 ?L BDNF modified BMSC solution were separately transfered into injury site of each group. MAIN OUTCOME MEASURES: The retrograde horseradish peroxidase tracing was practiced to observe neural cell number in the Lumbar 4 and 5 spinal cord anterior horn at 2 and 4 weeks after microinjection. Sciatic nerve function index was used to observe rat motor function of injured limbs. Fluorescence excitation and immunohistochemistry were employed to detect BMSC survival and BDNF expression. RESULTS: Cell number was more, and nerve function recovery was better in the Lumbar 4 and 5 spinal cord anterior horn in the BDNF gene-modified BMSC group than in the PBS and BMSC groups. BMSC survival was found in the injured sites in the BMSC and BDNF gene-modified BMSC groups. BDNF expression was significantly more in the BDNF gene-modified BMSC group than in the BMSC group. CONCLUSION: BDNF gene-modified BMSCs have promotion effects on the recanalization and functional recovery of nerve fiber following peripheral nerve injury.

Objective To discuss the clinical value of bidirectional quantitative detection of MSCT in the diagnosis of diabetic lung injury.Methods From May 2016 to July 2017,120 patients with diabetes in Wenzhou Hospital of Traditional Chinese Medicine were selected as diabetic group,and 50 healthy people were selected as control group.The two groups received the pulmonary function test ( PFT) and the MSCT bidirectional quantitative detection,the test results of the two groups were analyzed.And the correlation of indicators of MSCT bidirectional detection and PFT detection indicators was analyzed.Results After examination,the maximum inspiratory lung volume (Vin),maximum expiratory volume (Vex),respiratory volume (EVvin,EVvex)-emphysema,EIvin (%),EIvex (%) in the diabetic group were (3 627.64 ±867.43)mL,(3 785.34 ±835.64)mL,(476.95 ±326.25)mL,(236.53 ±86.18)mL,(9.26 ±4.85)%,(4.11 ±2.58)%,respectively,which were significantly lower than those in the control group (t＝11.151,13.809,21.317,21.623,24.76,26.708,all P＜0.05).The Vin,Vex,EVvin,EVvex,EIvin(%),EIvex(%) in the patients with ≤5 years of diabetes were (3 627.64 ±867.43)mL,(3 785.34 ± 835.64)mL,(326.25 ±56.95) mL,(236.53 ±86.18) mL,(9.26 ±4.85)%,(4.11 ±2.58)%,respectively,which were significantly higher than those in the patients with ＞5-10 years of diabetes mellitus (t＝129.09,36.01,21.03,12.38,22.17,19.48,all P＜0.05).Conclusion MSCT bidirectional quantitative detection is of great signif-icance for patients with diabetes lung injury,and plays a significant role in clinical treatment.

Objective:To analyze the supervision mode and problems of intensive countywide medical communities and explore the methods and strategies to improve their supervision system.Methods:From March 2022 to May 2022, a stratified random sampling method was used and the intensive countywide medical communities in the province were selected for field study. In-depth interviews were made with the staff of the healthcare administration departments and health insurance agencies affiliated with intensive countywide medical communities, directors of general hospitals, directors of township hospitals, and heads of functional departments. These interviews mainly covered the principal entities of countywide medical community supervision, supervision measures and contents, supervision effects, supervision weaknesses, and how to improve internal and external supervision mechanisms. The interviews results were analyzed using thematic framework analysis and the data were subject to a descriptive analysis.Results:23 persons of five intensive countywide medical communities were selected for key person interview. The finalized framework of regulatory elements of intensive countywide medical communities consists of such five general themes as regulatory subjects, regulatory content, regulatory measures, regulatory effectiveness and existing problems, comprising 14 level-1 indicators and 52 level-2 indicators. The main regulatory bodies were mainly government departments (15 times), the regulatory content was focused on medical resources (10 times), the regulatory measures cover specific regulations (4 times), specific activities (4 times) and assessment and evaluation (4 times). And the regulatory effectiveness demonstrated a currently strong regulation strength of medical communities (5 times), and the existing problems were insufficient government supervision (12 times), difficulties encountered by social forces in their supervision (11 times) and internal governance (5 times).Conclusions:The supervision system of intensive countywide medical communities should be optimized by improving the governmental supervision mechanism, inviting supervision of social forces and building an effective internal governance.

Objective To explore the effect of transcutaneous electrical acupoint stimulation bracelet at Neiguan acupoint on the postoperative nausea and vomiting after thyroidectomy under general an-esthesia.Methods Seventy-two female patients underwent thyroidectomy,aged 18-50 years,ASA physical status Ⅰ or Ⅱ,were enrolled.The patients were assigned 1 ∶ 1 to two groups by permuted block randomization:the electrical stimulation group and the control group,36 patients in each group.Before an-esthesia induction,patients in both groups wore domestic transcutaneous electrical acupoint stimulation bracelets,and the electrodes were aimed at Neiguan acupoint.The electrical stimulation group started to stimulate Neiguan acupoint,and adjusted the proper intensity to make the patient feel tingling in the related area of the hand.When the bracelet was fixed firmly,turned it off.At the end of the operation,the bracelet was turned on with the stimulation intensity set before induction for 24 hours.Patients in the control group also wore the bracelet for 24 hours,but it was never turned on.The number of cases of postoperative nausea and vomiting(PONV)and the number of remedial cases of antiemetic drugs were recorded.Results Compared with the control group,the incidence of PONV and postoperative vomiting in the electrical stimula-tion group were significantly reduced within 24 hours after surgery(P＜0.05),and the differences were mainly in 1-6 hours after surgery(P＜0.05).There was no significant difference in the rate of remedial ca-ses of antiemetic drugs between the two groups at different time periods.Conclusion Transcutaneous electri-cal stimulation bracelet at Neiguan acupoint can effectively reduce the incidence of PONV within 24 hours after thyroidectomy.

Objective To analyze the epidemiological characteristics of norovirus infectious diarrhea in the active monitoring of foodborne diseases in Jiangsu Province from 2015 to 2020, so as to provide reference for the prevention and control of foodborne diseases caused by norovirus. Methods Norovirus positive diarrhea cases were collected from sentinel hospitals in 13 districts and cities of Jiangsu Province, and their epidemiological and clinical characteristics were analyzed. Results Atotal of 3 620 norovirus positive cases were detected and isolated from 61 489 samples. The main serotype was GII (71.97%), the onset season was winter and spring, and the onset age was 1-3 years old and 14-34 years old. There was no significant difference in norovirus positive rate between different sexes, and the main symptom was diarrhea (incidence rate was 92.10%), Meat and meat products (20.20%) were the main types of suspected exposed foods. Conclusion Norovirus infection has obvious seasonal characteristics, and the population is generally susceptible. It is high in children and young people, and meat food was the main suspicious exposure food. We should continue to improve the ability of active monitoring, identification, early warning and control of foodborne diseases, so as to reduce the occurrence of foodborne diseases.

OBJECTIVETo study the prevalence of ALK, ROS1 and RET fusion genes in non-small cell lung cancer (NSCLC), and its correlation with clinicopathologic features.

METHODSFormalin-fixed and paraffin-embedded tissue sections from samples of 302 patients with NSCLC were screened for ALK, ROS1, RET fusions by real-time polymerase chain reaction (PCR). All of the cases were validated by Sanger DNA sequencing. The relationship between ALK, ROS1, RET fusion genes and clinicopathologic features were analyzed.

RESULTSIn the cohort of 302 NSCLC samples, 3.97% (12/302) were found to contain ALK fusion genes, including 3 cases with E13; A20 gene fusion, 3 cases with E6; A20 gene fusion and 3 cases with E20; A20 gene fusion. There was no statistically significant difference in patient's gender, age, smoking history and histologic type. Moreover, in the 302 NSCLC samples studied, 3.97% (12/302) were found to contain ROS1 fusion genes, with CD74-ROS1 fusion identified in 9 cases. There was no statistically significant difference in patients' gender, age, smoking history and histologic type. One non-smoking elderly female patient with pulmonary adenocarcinoma had RET gene fusion. None of the cases studied had concurrent ALK, ROS1 and RET mutations.

CONCLUSIONSThe ALK, ROS1 and RET fusion gene mutation rates in NSCLC are low, they represent some specific molecular subtypes of NSCLC. Genetic testing has significant meaning to guide clinical targeted therapy.

Objective: To investigate the pathological features and clinical manifestation of pediatric nodal marginal zone lymphoma(NMZL). Methods: Histological morphology and immunophenotype of 7 cases of pediatric NMZL were retrospectively reviewed at Beijing Friendship Hospital Affiliated to Medical University between January 2008 to October 2018. Clonal rearrangement analysis was performed. Clinical information including patient follow-up data were analyzed. Results: All 7 patients were male with a median age of 15 years aged from 10 to 26 years. All patients presented with only lymph node enlargement without B symptoms, including cervical lymph node (5 cases), preauricular lymph node (1 case) and retroauricular lymph node (1 case). Histologically, all cases showed irregular large follicles on the edges with widened marginal areas and intervesicular areas, and lesional cells were uniform with progressive transformation of germinal center centers along with a small amount of intrinsic lymphoid tissue. All 7 cases showed diffuse CD20 positivity both follicle and interfollicular region along with 30%-40% positivity in the interfollicular region (pathological region). Markers of other B-cell lymphomas werenot expressed. All 7 cases were positive for immunoglobulin(Ig) gene rearrangement. None of the patients showed no recurrence up on after follow-up for an average of 13 months. Conclusions Pediatric NMZL is a rare type of lymphoma that has a unique morphology and occurs almost exclusively in male children and young adults and often in head and neck lymph nodes. It has an excellent prognosis. Therefore, awareness of the disease with accurate diagnosis is important.
