Objective To investigate the morphological and functional alterations of peritoneum in uremic rats undergoing peritoneal dialysis(PD). Methods Thirty-five male Wistar rats were randomly divided into control group(sham operated group,n=6),uremia group(5/6 nephrectomy,n=6) and uremia with PD group(n=18).Uremia with PD group was subdivided into three subgroups according to different dialysis period(10 d,4 weeks and 8 weeks,n=6).Omenta were obtained for morphological examination,and peritoneal equilibration tests(PET) were performed to assess the transport function of peritoneal membrane. Results The number of blood vessels per high-power field in the uremia group,uremia with PD group and uremia with PD subgroups(5?3,10?5,17?5 and 19?4) were significantly increased compared with the control group(1?1),and that was much bigger in the uremia with PD group than the uremia group(P

AIM: To explore the effect of L-carnitine on nuclear factor of activated T-cells, cytoplasmic 3 (NFATc3) in cardiomyocytes under H2O2 stimulation.METHODS: Primary cultured neonatal rat myocardial cells were stimulated by H2 O2 at concentration of 200μmol/L for 12 h to induce oxidative stress injury.In treatment group, L-carni-tine and cyclosporin A ( CsA) , a specific inhibitor of calcineurin ( CaN) , were administered 30 min prior to H2 O2 stimula-tion.After treatment, total, cytoplasmic and nuclear NFATc3 protein levels were determined by Western blotting.The method of immunofluoresence was used to evaluate the distribution of NFATc3.RESULTS: H2 O2 treatment produced no effect on the expression of total NFATc3, but caused its translocation from the cytosolic to nuclear compartment, which was greatly blunted by L-carnitine pretreatment.CONCLUSION:L-carnitine antagonized oxidative stress injury via alleviating NFATc3 nuclear translocation.

Objective:To investigate the differences in efficacy, survival outcomes, and acute and late toxicities for patients with local/regional advanced nasopharyngeal carcinoma (NPC) treated by intensity-modulated radiotherapy (IMRT) in combination with che-motherapy (CT) and by IMRT alone. Methods:A total of 72 newly diagnosed local/regional advanced NPC patients were randomly subjected to IMRT/RT+adjuvant CT (after radiotherapy, RT) (n=42) or IMRT+adjuvant CT (after RT) (n=30). The Kaplan-Meier meth-od was used to analyze the two-year local/regional control rates, distant metastasis-free survivals, and overall survivals. The acute and late radiation toxicities were evaluated based on the toxicity criteria of the Radiation Therapy Oncology Group and European Organiza-tion for Research and Treatment of Cancer. Results:A median follow up period of 13.5 months was included in the study. The one-year and two-year local/regional control rates, distant metastasis-free survivals, and overall survival in the IMRT group were 95.0%, 80.0%, and 95.0%, and 80%, 60.0%, and 75.0%, respectively. For the IMRT+CT group, such rates were 100%, 96.4%, and 96.4%, and 100%, 92.9%, and 92.9%, respectively. The two-year local/regional control rate and distant metastasis-free survivals in the IMRT+CT group were higher than those in the IMRT group (P<0.05). Most patients had grade 1 to grade 2 acute radiation toxicities and grade 0 to grade 1 late radiation toxicities (P>0.05). No patient showed a grade 4 acute or late toxicity. The blood and gastrointestinal toxicity rates were high in the IMRT+CT group (P<0.05). Conclusion:The IMRT+CT treatment has potential advantages over the IMRT in the treatment of local/regional advanced NPC patients in terms of local/regional control and overall survival. The blood and gastrointestinal toxicity rates in the IMRT+CT group were higher than in the IMRT group but still within a tolerable range.

OBJECTIVETo evaluate the clinical effects of single posterior debridement, bone grafting, internal fixation and local chemotherapy in treating thoracolumbar spinal tuberculosis.

METHODSFrom February 2009 to September 2012,11 patients with thoracolumbar spinal tuberculosis were treated by single posterior debridement, bone grafting, internal fixation and local chemotherapy. There were 7 males and 4 females, aged from 27 to 65 years old with an average of 53.7 years. The courses of disease was from 3 months to 2 years with the mean of 9 months. According to ASIA standard of spinal cord injury, 3 cases were grade C and 8 cases D. After treatment, clinical effects were evaluated by ASIA grade, visual analogue score (VAS) and Oswestry Disability Index (ODI); kyphosis Cobb angle change was observed by X-rays.

RESULTSEleven patients were followed up from 12 to 29 months with an average of 18 months. ASIA grade of spinal cord injury, 3 patients with grade C improved to grade D in 2 cases and grade E in 1 case 8 patients with grade D improved to grade E in 7 cases and unchanged in 1 case. VAS decreased from preoperative 6.10 ± 1.30 to 1.70 ± 0.80 at 3 d after operation (P < 0.05). ODI improved from preoperative (68.36 ± 10.41)% to (14.55 ± 8.99)% (P < 0.05) at 3 d after operation. Kyphotic Cobb angle was corrected from preoperative (22.64 ± 4.84)° to (4.27 ± 1.49)° (P < 0.05) on the 3rd day after operation, and angle loss was mild at final follow-up, there was no significant difference between postoperative at 3 d and final follow-up.

CONCLUSIONSingle posterior debridement, bone grafting, internal fixation and local chemotherapy for the treatment of thoracolumbar spinal tuberculosis can effectively remove the lesion, improve nerve function and correct deformity, has advantage of single incision, little trauma, and low recurrence rate. But it still need long-term and systemic treatment with anti-TB drugs.

The mechanism of degenerative intervertebral disc is very complex, which may be associated with multiple factors such as the mechanical stress force injury of intervertebral disc, nutritional deficiency, inflammatory stimulation, etc. Recently, many studies detected propionibacterium acnes(P. acnes) in degenerative intervertebral disc and supposed P. acnes was associated with degenerative intervertebral disc. Here, the papers related to P. acnes and degenerative intervertebral disc were reviewed. Further, we deduced the approach of P. acnes enterring into the intervertebral disc as well as the mechanism of P. acnes aggravating the disc degeneration. These may provide suggestions for treating degenerative intervertebral disc.

Abstract: Objective　To analyze the distribution characteristics of the main pathogens of HIV/AIDS patients with wound infections and provide basis for clinical diagnosis and treatment. Methods　The clinical data of 294 patients with positive secretions or pus specimens from 2016 to 2020 were analyzed retrospectively. Results　A total of 357 strains of pathogenic bacteria were isolated from 294 cases, of which 123 strains of Gram-negative bacilli (G-b), accounting for 34.5%, were mainly Escherichia coli (15.4%), Klebsiella pneumoniae (3.9%), and Pseudomonas aeruginosa (3.6%); Gram-positive bacilli (G+b) 14 strains, accounting for 3.9%; 108 Gram-positive cocci (G+c), accounting for 30.3%, of which 44 strains were coagulase-positive Staphylococcus aureus (12.3%), Coagulase-negative staphylococci were mainly Staphylococcus epidermidis (4.2%) and Staphylococcus hemolyticus (2.8%); 37 strains of fungi, accounting for 10.4%, were mainly Candida albicans (5.9%); 75 strains of Mycobacterium, accounting for 21.0%, including 41 strains of Mycobacterium tuberculosis (11.5%) and 34 strains of non-tuberculosis mycobacteria (9.5%). 52 of the 294 HIV/AIDS patients had mixed infections, accounting for 17.7%. There was significant difference in the distribution of G+c, G-b, mycobacteria and mixed infection among different specimen sources (P<0.05), and there was significant difference in the distribution of mycobacteria among different CD4+T lymphocyte counts (P<0.05). There was significant difference in the level of CD4+T lymphocytes between patients of different ages (P<0.05), and there was significant difference in the level of CD4+T lymphocytes from postoperative incision and other parts (P<0.05). Conclusions　Patients with HIV/AIDS are prone to combined wound infections with various pathogenic bacteria. We should strengthen the research on wound infection in HIV/AIDS patients, and timely send patients with a low number of CD4+T lymphocytes for secretion or pus culture, so as to carry out targeted treatment and improve the prognosis of patients.
