Objective To study the method, advantage and shortcoming of mini-laparoscopic treatment for indirect inguinal hemia in children. Methods 136 cases with indirect inguinal hernia(right:75cases,left:44 cases,bilateral:17 cases) had been treated by high ligation with mini-laparoscopy. Results The mean operation time was 10 mmin for unilateral hernia and 23 mmin for bilateral hernia. Among 119 cases with unilateral hernia,38 cases had been found with contralateral latent hernia. The mean of postoperative inhospital stay were about 1 ~ 2 day(s). All patients had been followed-up for 3 ~ 12 months,there were only 2 cases recurrence found but no complications was detected.Conclusion Mini-laparoscopic high ligation for indirect inguinal hernia in children is a single, safe, satisfactory, effective,and minimally invasive surgical method.

Objective To study medial umbilical ligament in the prevention of recurrence of indirect inguinal hernia with large sac by laparoscopic treatment in children.Methods The clinical data of 178 cases of indirect inguihal hernia with large sacs in children were retrospectively analyzed.After high suture ligation of the internal ring with pediatric laparoscopy,all of the internal tings were covered with the same side of medial umbilical ligament to further strengthen.Results All cases were discharged from hospital 1~2 days after surgery.No recurrence and no any other complications could be found after following up 3~18 months.Conclusion Pediatric laparoscopic application of medial umbilical ligament to further cover the internal ring could significantly reduce the rate of recurrence for indirect inguinal hernia with large sac.This method of operation waft safe and feasible.It Was worth promoting.

Objective To explore the application of mini-laparoscopy in the diagnosis and management of nonpalpable undescended testis in children.Methods 38 cases of impalpabal testes(46 testicular) had been operated by mini-laparoscopy in children with cryptorchidism.Results 38 children with nonpalpable undescended testis (46 testicular) had been operated by mini-laparoscope.Results After laparoscopic exploration,inguinal probe and postoperative pathology,it had been confirmed that 2 testicular were absent,34 testicular were found in high inguinal location,10 testicular were located in intraperitoneal cavity.In addition to the absent testicular,the rest had been performed with mini-laparoscope:one period descent fixation 41 testes,Fowler-Stephens (F-S) installment orchiopexy three testes.Follow-up with side testicular atrophy 2,including one period orchiopexy a testis,F-S installment fixation a testicular; Testicular rebound 1,who had been operated with one phase of testicular descent fixtion.Conclusion For inguinal failed to find the testicular,children with cryptorchidism should be done by laparoscopy because of its positioning accuracy,and most children can do a period drop fixed,but for those really intraperitoneal more exalted person,stage surgery should be needed.Its overall treatment effect is satisfactory and is worth popularizing.

Objective:To observe the morphological changes of the deep lumbar multifidus (DM) during rest and movement among persons with chronic low back pain (cLBP) using ultrasound imaging.Methods:Twenty-one cLBP patients and 30 pain-free healthy controls were studied. The resting thickness of the DM muscle was measured, and then its cross-sectional area and thickness during maximum voluntary isometric contraction (MVIC). The results were correlated with pain intensity and duration.Results:The cLBP patients showed significant reductions in the DM′s resting thickness, and in its cross-sectional area and thickness during a MVIC compared with the healthy controls. The resting thickness of the DM was positively correlated with pain duration, but not with pain intensity.Conclusions:These results suggest that cLBP patients have atrophy and less thickness change during an MVIC. This should be considered in planning clinical rehabilitation training.

Objective To explore the reasons and management of early relapse of pediatric acute intussusception after enema reduction. Methods Clinical data of 48 patients with early relapse of pediatric acute intussusception after enema reduction were retrospectively collected and analyzed, especially for X-ray data during enema. Relevant management methods were proposed. Results In the comparison of gender, age, admission time and enema pressure between the early relapse group and non-relapse group of children patients, without statistically significant differences(χ2 all <3.84,P>0.05). However, as for①whether X-ray sign of intestinal obstruction could be seen during diagnosis,②whether intus-suscepted parts could be clearly seen after reduction, ③whether intussuscepted parts became larger after pressure re-lief, and ④inflation of small intestine after reduction compared between the two groups, with statistically significant differences (χ2 all>3.84,P<0.05). Patients in the relapse group were all given a secondary enema reduction. Conclu-sion During early stage after reduction of intussusception by air enema, possibilities of relapse or multiple relapses should still be noticed. Observations of multiple repeated changes of body position during enema and special attention to changes of intussuscepted parts are one of critical factors for reducing relapses and ensuring a success for secondary enema. A secondary air enema can be carried out when mastering the indications.

Objective To study changes in immune cells and cytokines during the reactivation stage of varicella-zoster virus(VZV)in patients with herpes zoster.Methods A total of 50 patients with herpes zoster and 30 healthy individuals were selected from Xi'an Ninth Hospital between May 2022 and October 2022.Flow cytometry was used to detect the proportion of peripheral blood CD3+cells,CD4+cells,CD8+T cells,B cells and NK cells,as well as levels of cytokines IL-2,IFN-γ,IL-10 and IL-6.We analyzed the immune mechanism of VZV reactivation stage in herpes zoster patients.Results Compared with the healthy control group,the proportion of CD3+cells and CD4+T cells in herpes zoster patients decreased significantly;the proportion of NK cells significantly increased;the levels of IFN-γ,IL-10 and IL-6 significantly increased;the proportion of CD8+T cells,B cells and IL-2 content showed an increasing trend,but there was no significant difference.In addition,the severity of neurological involvement in herpes zoster patients might affect changes in cytokine levels.Conclusion During the reactivation period of VZV,changes in the proportion of immune cells and cytokine expression levels are closely related to the occurrence and development of herpes zoster.

【Objective】 To analyze the basic characteristics of whole blood donors from blood stations before and after the outbreak of COVID-19. 【Methods】 After excluding invalid data, data related to the basic characteristics of whole blood donors collected from 26 blood stations in China during 2018 to 2021 were statistically analyzed, including the trend of total whole blood donors, the number of repeated blood donors, the frequency of blood donation, the average age of donors and the recruitment of first-time blood donors. 【Results】 Affected by the epidemic, 8 out of 14 indicators were with large variations, accounting for 57%. The overall growth rate of total whole blood donors during the epidemic was higher than before the epidemic (P<0.05).The number of repeated blood donors has shown an increased trend, with a higher number during the epidemic than before (P<0.05). The frequency of blood donation was lower during the epidemic than before(P<0.05).Average ages of blood donors and female blood donors fluctuated widely during the epidemic, both higher than those before the epidemic(P<0.05).The donation rate of first-time blood donors <25 years old and ≥25 years old varied widely and irregularly during the epidemic (both P<0.05). The percentage of first-time blood donors fluctuated irregularly during the epidemic, with overall percentage lower than that before the epidemic(P<0.05). 【Conclusion】 Whole blood donors from 26 blood stations increased after the outbreak of COVID-19, and some indicators in certain areas showed significant fluctuations during the epidemic.
