OBJECTIVES: Platelet-to-lymphocyte ratio (PLR) has recently been investigated as a new inflammatory marker in many inflammatory diseases, including systemic lupus erythematosus and immunoglobulin A vasculitis. However, there were very few reports regarding the clinical role of PLR in patients with anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis. This study was thus undertaken to investigate the relationship between inflammatory response and disease activity in Chinese patients with myeloperoxidase-anti-neutrophil cytoplasmic antibody (MPO-ANCA) associated vasculitis. Furthermore, we evaluated whether PLR predicts the progression of end stage of renal disease (ESRD) and all-cause mortality. METHODS: The clinical, laboratory and pathological data, and the outcomes of MPO-ANCA associated vasculitis patients were collected. The Spearman correlation coefficient was computed to examine the association between 2 continuous variables. Cox regression analysis was used to estimate the association between PLR and ESRD or all-cause mortality. RESULTS: A total of 190 consecutive patients with MPO-ANCA associated vasculitis were included in this study. Baseline PLR was positively correlated with CRP (r=0.333, P<0.001) and ESR (r=0.218, P=0.003). PLR had no obvious correlation with Birmingham Vasculitis Activity Score (BVAS). Patients having PLR≥330 exhibited better cumulative renal survival rates than those having PLR<330 (P=0.017). However, there was no significant difference in the cumulative patient survival rates between patients with PLR≥330 and those with PLR<330 at diagnosis (P>0.05). In multivariate analysis, PLR is associated with the decreased risk of ESRD (P=0.038, HR=0.518, 95% CI 0.278 to 0.963). We did not find an association between PLR with all-cause mortality using multivariate analysis (HR=1.081, 95% CI 0.591 to 1.976, P=0.801). CONCLUSIONS PLR is positively correlated with CRP and ESR. Furthermore, PLR may independently predict the risk of ESRD.

Objective:To analyze the characteristics of the molecular transmission network of newly-diagnosed human immunodeficiency virus type 1 (HIV-1) infected individuals in Shaoxing City, Zhejiang Province, and to provide evidence for epidemic trend and prevention.Methods:The plasma samples from 423 antiretroviral-naive HIV-1/acquired immunodeficiency syndrome patients from August 2018 to December 2019 were collected, and the pol gene fragments of HIV-1 from 375 samples were amplified by reverse transcription polymerase chain reaction (PCR) and nested PCR. The phylogenetic tree was constructed to analyze the molecular transmission network for subtypes and different gene distances by MEGA 6.0 software, HyPhy software and Cytoscape 3.7.2. Mutations on drug resistance was analyzed by online software tool of the HIV drug resistance database of Stanford University. Results:Eight subtypes were found in the 375 samples. Circulating recombinant form (CRF)07_BC(215/375, 57.33%) and CRF01_AE(103/375, 27.47%) were the major subtypes, followed by CRF85_BC, CRF55_01B, B, C, and CRF01_AE/B subtypes. One hundred and ninety-four individuals (51.73%) were connected to the transmission network at 1.50% genetic distance with 24 clusters. One hundred and twenty-nine individuals (34.40%) were connected to the transmission network at 0.75% genetic distance with 30 clusters, and 35 elderly patients were clustered in CL1.Forty-two cases had surveillance drug resistance mutation (SDRM), the prevalence of transmitted drug resistance was 11.20%(42/375). Thirty-eight cases had the drug mutations to non-nucleoside reverse transcriptase inhibitor, including K103 N(32/375, 8.53%), K103 S(4/375, 1.07%), Y188 L(1/375, 0.27%) and G190 A(1/375, 0.27%); four cases had the mutations to protease inhibitor, including M46 I(3/375, 0.80%) and V82 A(1/375, 0.27%). The cluster C2 sequences carried a high proportion of resistant mutations (94.29%, 33/35). Conclusions:HIV-1 subtypes in Shaoxing City are diverse and the CRF07_BC subtype spreads rapidly. The elderly patients with drug resistance genes in cluster CL1 at 0.75% gene distance need to be intervened immediately to prevent the drug resistance virus spread.

Objective:To investigate the clinical effect of cluster nursing on the prevention of perioperative urinary catheter associated urinary tract infection (CAUTI) in patients with spinal fracture.Methods:A retrospective case-control method was used to select 160 patients with spinal fracture admitted to the department of spinal cord injury in emergency care from January 2018 to March 2020 in the Department of Orthopaedics General Hospital of Chinese People′s Liberation Army as study subjects, 80 patients admitted to the department of spinal cord injury from January to December 2018 were set as the control group, and 80 patients admitted from January 2019 to March 2020 as the observation group. The control group was given standardized clinical nursing measures during the perioperative period, while the observation group was given cluster nursing measures. The duration of indwelling of catheters, the incidence of catheter reinsertion and the incidence of CAUTI were compared between the two groups.Results:The catheter indwelling time in the observation group was (3.37±0.64) days, lower than that in the control group (6.35±1.52) days. The incidence of catheter insertion and CAUTI was 5.00%(4/80), 3.80%(3/80) in the observation group, lower than 11.30%(9/80), 11.60%(13/80) in the control group. The differences were statistically significant ( χ2 values were -2.927, -2.654, all P<0.05). Conclusions:Cluster nursing intervention for patients with spinal fracture in the perioperative period can effectively shorten the catheter indwelling time, reduce the incidence of catheter re-insertion and the incidence of patients with CAUTI, significantly improve the quality of clinical care in the department, and have positive significance for the treatment and rehabilitation of patients.

Objective:To investigate the effect of complete decongestive therapy in the treatment of severe grade Ⅲ lower limb lymphedema.Methods:From January 2018 to December 2018, The patients were admitted to the lymphedema clinic of the cancer prevention and treatment center of Sun Yat-sen University, seven patients with severe gradeⅢ lower limb lymphedema were intervened with complete decongestive therapy, including problem skin care, special techniques of unarmed lymphatic drainage, foam block bandage combined with air wave pressure therapy, filled elastic bandage pressure bandage, functional exercise combined with home bare-handed lymphatic drainage and weight loss management. The intervention had two courses, and 20 times was a course of treatment. Perimeter measurement and weight measurement were used to evaluate the therapeutic effect at the 0, 5, 10, 15, 20, 30, 40 times of treatment.Results:After two courses of treatment, the circumference value of each measurement point on the affected side was lower than that before treatment, and the difference was statistically significant ( F values were 7.449-23.073, P < 0.05). The circumference value of the affected side decreased by 7.10 - 24.53 cm, and the weight after treatment was 9.0 - 20.5 kg less than that before treatment. During the follow-up period, it was found that the lower extremity diameter value at 3 months of follow-up at 5 sites increased and tended to be stable compared with that at 1 year of follow-up. Conclusion:Step 6 comprehensive swelling treatment can obviously improve the symptoms of patients with lower limb lymphedema of this research, and in the subsequent follow-up found that self-therapy at home, no recurrence or aggravate the limb swelling degree, and can reduce or stability treatment effect, enhance confidence in the treatment of patients, so as to improve the quality of life of patients and treatment compliance.

Objective:To explore the effect of dynamic multi-dimensional management model based on informatization on improving the home self-care of lymphedema patients.Methods:A total of 80 patients who received lymphedema combined detumescence treatment from January 2018 to June 2018 were selected as the control group.From July 2018 to December 2018, 80 patients were treated as the intervention group, and the whole process was managed on the basis of the control group using the dynamic multidimensional management mode based on informatization. Patients' compliance and quality of life were compared between the two groups.Results:The intervention group patients' compliance was better than control group, correctly measure the circumference of limbs, the law of life that occupy the home was good, correct manual lymph drainage direction, bandages, functional exercise, 18 standards compliance, respectively, 95.0%(76/80), 87.5%(70/80), 97.5%(78/80), 95.0%(76/80), 100.0%(80/80), 87.5%(70/80), better than that of control group were 77.5%(62/80), 75.0%(60/80), 80.0%(64/80), 70.0%(56/80), 75.0%(60/80), 50.0%(40/80), difference was statistically significant ( χ2 values were 4.103-26.182, P<0.05 or 0.01). After a course of treatment and 3 months of home-based self-care, the scores of role function, physical function, emotional function and social function of the quality of life in the intervention group were (75.44 ± 2.78), (80.11 ± 3.01), (78.25 ± 2.78), (79.93 ± 5.43), which were better than those of the control group (66.25 ± 2.58), (75.88 ± 3.57), (65.16 ± 2.47), (62.78 ± 4.01), with statistically significant differences ( t values were 8.09, 31.50, P<0.01).

To observe the changes in serum interleukin-22 (IL-22) level and its correlation with other clinical indexes in patients with essential hypertension and hypertensive renal damage, and to investigate its effects and clinical significance.
 Methods: A total of 97 essential hypertension (EH) patients and 40 healthy control were enrolled in this study. The EH patients were divided into a simple hypertension (SH) group (n=45) and a hypertensive renal damage (HRD) group (n=52) according to 24 h urinary protein (24 h-UPRO) level. Basic clinical data were collected; serum IL-22 level was detected by enzyme-linked immunosorbent assay (ELISA); the proportion of Th22 cells in peripheral blood was evaluated by flow cytometry (FCM); and serum high sensitivity C-reactive protein (hs-CRP) concentration was measured by immune turbidimetry. Correlation analysis was applied between serum IL-22 level and other indexes.
 Results: Serum IL-22 level and Th22 cell proportion in patients with hypertension were significantly higher than those in the healthy controls (all P<0.01). Compared with the SH group, serum IL-22 level and Th22 cell proportion were significantly elevated in the HRD group (P<0.01, P<0.05, respectively). Bivariate linear correlation analysis revealed that serum IL-22 level was positively correlated with systolic blood pressure (SBP), diastolic blood pressure (DBP), and hsCRP (r=0.367, P<0.01; r=0.402, P<0.01; r=0.329, P<0.05); there was also a positive correlation between serum IL-22 concentration and Th22 cell proportion (r=0.478, P<0.01) in the SH group. Serum IL-22 level was positively correlated with 24 h-UPRO level (r=0.318, P<0.05) in the HRD group.
 Conclusion: Serum IL-22 level and peripheral blood Th22 cells are significantly increased in the HRD group compared with the SH group. Serum IL-22 level is closely correlated with extent of hypertensive renal damage, indicating that serum IL-22 level may involve in the pathogenesis of hypertensive renal damage.

Objective To evaluate the efficacy of pivot-regulating manipulations applied in traditional Chinese medicine (TCM) clinical nursing for infantile anorexia based on the meridian and acupoint theory. Methods One hundred and twenty children with anorexia were randomly divided into trial group and control group , 60 cases in each group. The control group was given spine-pinching therapy based on the conventional nursing care. The trial group was given pivot-regulating manipulations based on the conventional nursing care , and the pivot-regulating manipulations covered manipulating spleen -stomach meridian , regulating Neibagua, kneading Banmen, kneading abdomen, manipulating acupoints of Zhongwan, Tianshu and Zusanli, and pinching spine according to the deficiency-excess differentiation, once every other day and 3 times constituting one course of treatment. After treatment for 2 courses, the clinical efficacy of the two groups was evaluated. The changes in TCM symptom scores and physical examination indexes of body height, body mass, head circumference, chest circumference, height-for-age (HT/A), weight-for-age (WT/A) in the two groups were observed before and after treatment. Results(1) Five cases(3 differentiated into excess syndrome and 2 into deficiency syndrome) of the trial group dropped out and quitted from the trial, and 6 cases of the control group dropped out and quitted from the trial. (2) After two courses of treatment, the total effective rate of the trial group was 94.55％, and that of the control group was 87.04％, the difference being significant (P < 0.05). (3) After treatment, the scores of appetite and food-intake amount, complexion and lip color, water intake, restlessness, and urination as well as TCM symptom scores in both groups were improved; the WT/A of the trial group was also improved (P < 0.05 compared with those before treatment). The trial group had better effect on improving the scores of appetite and food-intake amount, complexion and lip color, and restlessness as well as TCM symptom scores than the control group (P < 0.05 or P < 0.001). The trial group also showed better effect on improving body mass, body height, head circumference, and HT/A than the control group(P<0.05). Conclusion As a nursing method based on the meridian and acupoint theory as well as syndrome differentiation and treatment, pivot-regulating manipulations are effective for the treatment of infantile anorexia by quickly starting an effect and obviously relieving the symptoms.

Objective To explore the effects of seven-step complex decongestion therapy (CDT) on post-operative upper limb lymphede-ma of breast cancer. Methods From August, 2015 to September, 2016, 71 patients with upper limb lymphedema after breast cancer surgery accepted CDT for 20 days, including skin care, opening of lymphatic pathway, relief of scar tissue, manual lymphatic drainage, bandage compression, air pressure wave therapy and functional exercise. The circumference of eight sites of both limbs was measured and the differ-ences were calculated before treatment, and one, five, ten, fifteen and twenty days of the treatment. Results The differences of circumfer-ence increased one to 15 days of the treatment (Z>2.03, P<0.05), and decreased 20 days of the treatment (Z=3.01, P<0.01). Conclusion CDT is effective on lymphedema after breast cancer surgery for 20 days of a course, but may worsen in the first 15 days, which may be relat-ed to acute stress response or redistribution of lymph.
