Methods: The PC12 cell were treated with terminal concentrations of 0, 25, 50, 100, 200, 300 and 400 μmol/L PQ for 24 hours, and the cells were induced by 300 μmol/L PQ for different time (6, 12, 24, 48 h) . MTT was used to detect the relative survival rate of cells, and the dose/time-effect relationship was determined respectively. The cells were treated with PQ at concentrations of 0, 100, 200 and 300 μmol/L PQ for 24 hours, the lactate dehydrogenase (LDH) activity in the culture supernatant was detected by spectrophotometry. The expression and distribution of autophagic lysosomes were observed by MDC staining. The intracellular reactive oxygen species (ROS) was detected by dichlorofluorescein diacetate (DCFH-DA) . The expression of microtubule-related protein 1 light chain 3 (LC3) was measured by immunofluorescence. The protein level of LC3Ⅱ, p62, Beclin1 and p-AMPK, p-mTOR were detected by Western blot.

Compared with the control group, the activity of LDH in 100, 200, 300 μmol/L PQ-treated group were significantly higher while The fluorescence intensity of ROS was significantly increased (P<0.05) . MDC staining showed the density of autophagic lysosomes and fluorescence intensity in PQ-treated group significantly decreased (P<0.05) . Immunofluorescence results showed the LC3 fluorescence intensity of PQ-treated group decreased which was consistent with MDC staining results. Western blot showed that compared with the control group, the expression levels of autophagy related proteins LC3Ⅱand Beclin1 in PQ-treated group were significantly lower, while the expression level of p62 protein was higher (P<0.05) . p-AMPK protein level decreased and p-mTOR protein expression increased in 200 and 300μmol/L PQ-treatd groups, with statistically significant difference (P<0.05) .

Objective To explore the application value of vacuum sealing drainage (VSD) in wound repair after resection of pilonidal sinus.Methods The retrospective cross-sectional study were conducted.The clinical data of 11 patients with pilonidal sinus who were admitted to the China-Japan Union Hospital of Jilin University from April 2015 to June 2016 were collected.All the patients received resection of pilonidal sinus after preoperative antibiotic therapy,and then received postoperative VSD and regular treatments of anti-infection and dressing changes.Observation indicators:(1) treatment situations:surgical procedures,operation time,volume of intraoperative blood loss,gross specimens,results of postoperative pathological examination,postoperative treatment (VSD),growth condition of granulation tissue,duration of hospital stay and treatment expenses;(2) follow-up situations:cases with follow-up,follow-up time,wound healing,postoperative complications and disease recurrence.Follow-up using outpatient examination and telephone interview was performed to detect the wound healing,postoperative complications and disease recurrence up to July 2017.Measurement data with normal distribution were represented as (x)±s.Measurement data with skewed distribution were described as M(range).Results (1) Treatment situations:all the 11 patients underwent successful surgery for pilonidal sinus.The operation time and volume of intraoperative blood loss were respectively (79 ± 19) minutes and (10 ± 4) mL.Observation of gross specimens of 11 patients:hairs were scattered within the resected lesions in 7 patients,and hairs didn't found in 4 patients.Results of postoperative pathological examination of 11 patients:there were acute and chronic inflammation accompanied with granulation tissues in the subepithelial fibrous tissues,and discrete multinucleated giant cell reaction.Of 11 patients undergoing VSD,9 received VSD material changes for 3 times,2 received VSD material changes for once,and wounds were not sutured after VSD removal.The new granulation tissues of 11 patients were found at (5.9±1.3) days postoperatively.The duration of hospital stay and treatment expenses were respectively (33.3±8.3) days and (37 790± 8 811) yuan.(2) Follow-up situations:11 patients were followed up for 12-18 months,with a median time of 14 months.The wound healing time was (41.0±9.0)days.Of 11 patients with follow-up,10 were in the primary healing,1 who was complicated with wound infection and abscess of wound deep surface underwent sacral wound incision and drainage,gauze packing and routine dressing change,and then wound healed completely.There was no recurrence in 11 patients during the follow-up.Conclusions The VSD has great application value in managing wounds after resection of pilonidal sinus,with a lower incidence of wound infection and smaller scar,and it is worth recommending to patients with wide wounds,high tension and serious infection.

To summarize the clinical manifestations of a case with 46, XY sex development disorder caused by myelin regulatory factor(MYRF) gene mutation and review the literature to deepen the specialists′ understanding of the clinical disease spectrum resulting from MYRF gene variations. The child had a female phenotype with mild masculinity, chromosome 46, XY, sex-determining region of Y gene(SRY gene) positive, laboratory tests were consistent with primary hypogonadism, ultrasound did not detect the gonads, but the residual reproductive tract was visible, and echocardiography suggested coarctation of the aorta, MYRF gene c. 2518C>T(p.R840*) heterozygous variant. The father did not carry this variant. The mother was untraceable, and genetic testing had not been completed. It was analyzed as pathogenic variation according to American College of Medical Genetics and Genomics(ACMG) guidelines. Sixteen cases of disorders of sex development caused by MYRF gene variation reported from 2018 to 2021 were reviewed, MYRF gene variants, 46, XY, and 46, XX individuals can be pathogenic, can affect the gonad and reproductive tract at the same time, and can also affect multiple systems. In this case, the patient presents with 46, XY sex development disorder due to MYRF gene mutation, accompanied by rare cardiovascular complications. When encountering 46, XY primary hypogonadism without well-developed Müllerian duct structures, this condition should be considered. Following confirmation, a comprehensive assessment of multi-organ function is necessary.

Objective To investigate the inhibitory effect of ursolic acid in Hippophae rhamnoides L. on hepatocyte apoptosis in rats with alcoholic liver disease based on the mitochondria-cytochrome c pathway. Methods A total of 50 specific pathogen-free male Wistar rats were divided into normal control group, alcohol model group, and low-, middle-, and high-dose ursolic acid groups using a random number table, with 10 rats in each group. The rats in the normal control group were given normal saline by gavage once a day for 8 weeks; the rats in the alcohol model group were given alcohol at increasing concentrations by gavage for 8 consecutive weeks; the rats in the low-, middle-, and high-dose ursolic acid groups were given ursolic acid at a dose of 50, 100, and 150 mg/kg, respectively, followed by an equal volume of alcohol as the model group 1 hour later. Serum liver function parameters were measured for each group; HE staining was used to observe liver histopathology; an electron microscope was used to observe hepatocyte ultrastructure; the TUNEL method was used to measure hepatocyte apoptosis; Western Blotting was used to measure the protein expression levels of cytochrome c and activated caspase-3 in hepatocyte mitochondria and cytoplasm. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups. Results Compared with the alcohol model group, the middle- and high-dose ursolic acid groups had significant reductions in the serum level of alanine aminotransferase, aspartate aminotransferase, and cholinesterase (all P < 0.05). The rats in the alcohol model group had disordered arrangement of hepatic cords with marked hepatocyte edema and fatty degeneration, while those in the middle- and high- dose ursolic acid groups had basically normal arrangement of hepatic cords and a significant improvement in hepatocyte fatty degeneration, as well as a significant increase in the number of hepatocyte mitochondria and a significant improvement in morphology. Compared with the alcohol model group, the middle- and high-dose ursolic acid groups had significantly lower hepatocyte apoptosis rate and protein expression levels of cytochrome c and caspase-3 in cytoplasm (all P < 0.05). Conclusion Ursolic acid in Hippophae rhamnoides L. can improve the liver function and histomorphology of rats with alcoholic liver disease, possibly by inhibiting the release of cytochrome c in hepatocyte mitochondria, the activation of caspase-3, and the apoptosis of hepatocytes via the mitochondria-cytochrome c pathway.
