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.

Atherosclerosis is a complex disease characterized by lipid accumulation in the vascular wall and influenced by multiple genetic and environmental factors. To understand the mechanisms of molecular regulation related to atherosclerosis better, a protein interaction network was constructed in the present study. Genes were collected in nucleotide database and interactions were downloaded from Biomolecular Object Network Database (BOND). The interactional data were imported into the software Cytoscape to construct the interaction network, and then the degree characteristics of the network were analyzed for Hub proteins. Statistical significance pathways and diseases were figured out by inputting Hub proteins to KOBAS2. 0. The complete pathway network related to atherosclerosis was constructed. The results identified a series of key genes related to atherosclerosis, which would be the potential promising drug targets for effective prevention.

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 investigate the clinical characteristics, pathogen distribution and risk factors of late-onset sepsis (LOS) in very low birth weight infants (VLBWI).Methods:In this retrospective case-control study, 107 VLBWIs diagnosed with LOS and hospitalized in Fujian Provincial Maternity and Children's Hospital from January 1, 2010 to December 31, 2015 were enrolled as LOS group. Another 107 VLBWIs without infection were assigned as control group with an allocation ratio of 1 to 1. The clinical data between groups were compared using two-independent sample t-test, Chi-square test, sum-rank test and univariate analysis of variance, and multivariate logistic regression was used to analyze the risk factors of LOS. Results:The incidence of LOS in VLBWI was 8.6% (107/1 239). Among the 107 cases with LOS, 87 recovered with a cure rate of 81.3%. Various clinical presentations were observed, and the most common included lethargy (83/107, 77.6%), abdominal distention (77/107, 72.0%) and dyspnea (76/107, 71.0%). Increased C-reactive protein (CRP) level was the most common laboratory markers (82/107, 76.6%). The blood cultures were positive in 45 (42.1%) cases and the dominant pathogen was Gram-negative bacteria (32/45, 71.1%), especially Klebsiella. The logistic regression analysis showed that mechanical ventilation ( OR=21.181, 95% CI: 1.542-290.948, P=0.022), feeding intolerance ( OR=12.480, 95% CI: 2.602-59.856, P=0.002), combined application of antibiotics before LOS occurs ( OR=22.457, 95% CI: 3.933-128.237, P<0.001), duration of antibiotic treatment before LOS occurs ( OR=1.388, 95% CI: 1.158-1.663, P<0.001) were the independent risk factors of LOS for VLBWI. Conclusions:The clinical presentation of LOS in VLBWI are diverse and non-specific. Increased CRP level is a sensitive laboratory marker. The main pathogen is Gram-negative bacteria. LOS are more prone to occur in VLBWI with mechanical ventilation, feeding intolerance, combined application of antibiotics or long duration of antibiotic treatment.

“Stasis generating deficiency” is considered to be an important pathogenesis of recurrence after catheter ablation of atrial fibrillation （AF）. Blood stasis is commonly seen after ablation together with various pathogens such as phlegm-fire， qi stagnation and retained fluid， and will lead to depletion of zang-fu （脏腑） organs and then the failure of the nourishment of the heart. Therefore， it is advised to emphasize on the importance of considering zang-fu organs depletion caused by blood stasis and various excess pathogens in dealing with the recurrence after catheter ablation. The method of dissolving stasis and supplementing deficiency simultaneously has been proposed before catheter ablation， and it is critical to calm heart and dissolve stasis， regulate and supplement internal deficiency so as to prevent the postoperative recurrence of AF. For recurrence of AF after ablation， attention should be paid to dissolving stasis and dispelling pathogens， regulating vessels and supplementing deficiency， as well as the excess pathogens such as stasis binding and phlegm fire， stasis binding and qi stagnation， stasis binding and retained fluid， and the depletion of zang-fu organs should be considered. Accordingly， the method of dissolving stasis and dispelling phlegm， subduing fire and unblocking vessels， regulating and supplementing heart and spleen； dissolving stasis and move stagnation， unblocking qi and blood， supplementing lung and boosting qi； dispelling stasis and dissolving rheum， warming yang and activating blood， consolidating the root and nourishing heart can be used respectively， so as to treat both the root and the branch simultaneously.

OBJECTIVE: To determine features of the clinical manifestation in patients with primary biliary cirrhosis (PBC), and to provide a scientific basis for diagnosis of PBC.
 METHODS: A total of 102 patients with PBC treated in the Second Xiangya Hospital, Central South University, from January 2013 to January 2015 were retrospectively analyzed. The patients' general condition, clinical manifestations, serum biochemical and immunological parameters were detected.
 RESULTS: Of the 102 PBC patients, 91 (89.21%) patients were female. The main symptoms in these patients were fatigue, poor appetite, dry mouth, nausea, vomiting, pruritus, stomachache, and abdominal distension. The major signs were jaundice, splenomegaly, hepatomegaly, edema, and ascites. The main features of serum biochemical parameters in these patients included the increase of alkaline phosphatase and gamma glutamyltranspeptidase (GGT), especially the GGT. The anti-mitochondrial antibodies-M2 (AMA-M2) in 81 and 21 patients was positive and negative, respectively. The differences between the AMA-MA positive and negative groups were not statistically significant (P>0.05). According to clinical manifestation, 102 patients were classified into 2 groups: A non-cirrhosis group (n=56) and a cirrhosis group (n=46). The positive rates in these 2 groups, such as ANA, AMA-M2, anti-gp210, anti-Sp100, anti-Ro52, anti-PML, were 54.35%, 89.13%, 41.30%, 13.04%, 43.38% and 10.87% vs 57.14%, 71.43%, 42.86%, 12.5%, 51.79% and 3.71%, respectively, with no significant difference between them (P>0.05). However, there was significant difference in the positive rate of anti-3E-EPO between the above 2 groups (86.78% vs 58.93%, P<0.05). The positive rates of AMA-M2 and anti-3E-EPO in 30 patients diagnosed by hepatic histopathological examination were higher than those of other antibodies.
 CONCLUSION PBC mainly affects middle-aged women, and its clinical manifestation is various. The autoantibody tests play an important role in diagnosis of PBC. Checking for AMA-A2 and anti-3E-BPO can improve the positive rate of PBC. Liver histopathological examination may provide useful information on disease severity, which can determine the histological stage when the patient's serum autoantibodies are negative.
