Objective: To compare the effects of the China Children's Asthma Action Plan (CCAAP)-based remote joint management model with traditional management model on the control of childhood asthma. Methods: A retrospective cohort study was conducted to analyze the general data and asthma control assessment data of 219 children with asthma who attended the respiratory department of Guangzhou Women's and Children's Medical Center from April 2021 to October 2021 and were followed up for 1 year or more. According to the follow-up management model, the CCAAP-based remote joint management model was used in the observation group and the traditional management model was used in the control group, and the propensity score matching method was applied to match the data of children in the two management models for comparison. Paired-samples t-test, Wilcoxon signed-rank test, McNemar χ²-test or χ²-test or nonparametric tests were used to compare the general data and asthma control assessment data between the two matched groups of children. Results: Among 219 children with asthma, 145 were male and 74 were female, aged at consultation (7.2±2.4) years. There were 147 cases in the observation group and 72 cases in the control group, and 27 cases in each of the observation and control groups were successfully matched. The number of asthma exacerbation aura, acute exacerbations, and emergency room visits or hospitalizations for asthma exacerbations were lower in the observation group than in the control group after pairing (1 (0, 2) vs. 3 (1, 5) times, 0 (0,0) vs. 0 (0, 1) times, 0 (0,0) vs. 1 (0, 1) times, Z=-3.42, -2.58, -3.17, all P<0.05). The use of peak flowmeters was higher in children aged 5 years and older in the observation group than in the control group after pairing (100% (22/22) vs. 13% (3/23), χ²=54.00,P<0.001). The ratio of actual to predicted 1st second expiratory volume of force after follow-up in the observation group after pairing was higher than that before follow-up in the observation group and after follow-up in the control group ((95±11)% vs. (85±10)%, (95±11)% vs. (88±11)%, t=-3.40, 2.25, all P<0.05). The rate of complete asthma control after follow-up was higher in both the observation and control groups after pairing than before follow-up for 12 months in both groups (93% (25/27) vs. 41% (11/27), 52% (14/27) vs. 41% (11/27), H=56.19, 45.37, both P<0.001), and the rate of complete control of asthma in children in the observation group was higher than that in the control group at 3 and 12 months of follow-up management (56% (15/27) vs. 25% (5/20), 93% (25/27) vs. 52% (14/27), χ²=47.00, 54.00, both P<0.001). The number of offline follow-up visits, inhaled hormone medication adherence scores, and caregiver's asthma perception questionnaire scores were higher in the observation group than in the control group after pairing (6 (4, 8) vs. 4 (2,5), (4.8±0.3) vs. (4.0±0.6) score, (19.3±2.6) vs. (15.2±2.7) score, Z=6.58, t=6.57, 5.61, all P<0.05), and the children in the observation group had lower school absences, caregiver absences, asthma attack visit costs, and caregiver PTSD scores than the control group (0 (0,0) vs.3 (0, 15) d, 0 (0,0) vs. 3 (0, 10) d, 1 100 (0, 3 700) vs. 5 000 (1 000, 10 000) yuan, 1.3 (1.1, 1.9) vs. 2.0 (1.2, 2.7) score, Z=-2.89, -2.30, 2.74, 2.73, all P<0.05). Conclusion: The CCAAP-based joint management model of asthma control is superior to the traditional management model in the following aspects: it can effectively improve asthma control, self-monitoring, and lung function in children; it can improve treatment adherence and caregivers' asthma awareness; and it can reduce the duration of absenteeism from school, the cost of asthma exacerbation visits, and caregiver's negative psychology.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

BACKGROUNDWith the progress of perinatal medicine and neonatal technology, more and more extremely low birth weight (ELBW) survived all over the world. This study was designed to investigate the short-term outcomes of ELBW infants during their Neonatal Intensive Care Unit (NICU) stay in the mainland of China.

METHODSAll infants admitted to 26 NICUs with a birth weight (BW) < l000 g were included between January l, 2011 and December 31, 2011. All the data were collected retrospectively from clinical records by a prospectively designed questionnaire. The data collected from each NICU transmitted to the main institution where the results were aggregated and analyzed. Categorical variables were performed with Pearson Chi-square test. Binary Logistic regression analysis was used to detect risk factors.

RESULTSA total of 258 ELBW infants were admitted to 26 NICUs, of whom the mean gestational age (GA) was 28.1 ± 2.2 weeks, and the mean BW was 868 ± 97 g. The overall survival rate at discharge was 50.0%. Despite aggressive treatment 60 infants (23.3%) died and another 69 infants (26.7%) died after medical care withdrawal. Furthermore, the survival rate was significantly higher in coastal areas than inland areas (53.6% vs. 35.3%, P = 0.019). BW < 750 g and GA < 28 weeks were the largest risk factors, and being small for gestational age was a protective factor related to mortality. Respiratory distress syndrome was the most common complication. The incidence of patent ductus arteriosus, intraventricular hemorrhage, periventricular leukomalacia, bronchopulmonary dysplasia, retinopathy of prematurity was 26.2%, 33.7%, 6.7%, 48.1%, and 41.4%, respectively. Ventilator associated pneumonia was the most common hospital acquired infection during hospitalization.

CONCLUSIONSOur study was the first survey that revealed the present status of ELBW infants in the mainland of China. The mortality and morbidity of ELBW infants remained high as compared to other developed countries.

OBJECTIVETo investigate the frequencies of chemokine (C-C motif) receptor 5 gene (CCR5)Δ32 deletional mutation of in Han and Dai populations from Yunnan province. Immortalized cell lines were derived from a family carrying the CCR5Δ32 mutation.

METHODSBlood samples of 346 Han and 355 Dai individuals were collected for genotyping. The coding regions of CCR5 gene were amplified with PCR followed by agarose gel electrophoresis. Suspected mutations were verified with DNA sequencing. Immortalized cell lines were constructed by using Epstain Barr virus and cyclosporine A. The difference between the cell lines and original blood samples was verified with PCR.

RESULTSOne ethnic Han individual was confirmed to be heterozygous for a deletional mutation by sequencing, which has led to discovery of a family with CCR5Δ32. Nine immortalized cell lines were established from this family, and no difference between the cell lines and original blood samples was detected by PCR.

CONCLUSIONTogether with previous reports, this study has indicated a significant difference in CCR5Δ32 among different ethnic groups in China. Established immortalized cell lines can also provide material for future research.

OBJECTIVETo compare the treatment results of three-dimensional conformal radiotherapy (3D-CRT) and conventional radiotherapy (2D) for patients with locally advanced non-small-cell lung cancer (NSCLC).

METHODSFive hundred and twenty seven patients with stage III NSCLC treated between Jan 2000 and Dec 2006 were included in this study. Among them, 253 cases were treated with 3D-CRT, and 274 with conventional radiotherapy. In the 3D group, 159 (62.8%) patients received chemoradiotherapy, 77 with total radiotherapy dose of > 60 Gy, 49 with 50 - 60 Gy. In the 2D group, 127 (46.4%) patients received chemoradiotherapy, 48 with total radiotherapy dose of > 60 Gy, 75 with 50 - 60 Gy.

RESULTSThe 1-, 3-, 5-year overall survival rates (OS) and median survival time for patients treated with 3D-CRT were 73.3%, 26.1%, 14.4% and 20.1 months, respectively, and that of patients treated with 2D radiotherapy were 61.0%, 13.8%, 8.0% and 15.6 months, respectively (P = 0.002). The 1-, 3-, 5-year cause-specific survival rates (CSS) were 79.0%, 33.3%, and 20.8% for the 3D group and 65.1%, 16.7%, 11.2%, respectively, for the 2D group (P = 0.000). The 1-, 3-, and 5-year locoregional control rates were 71.6%, 34.3% and 31.0% for patients treated with 3D radiotherapy and 57.3%, 22.1% and 19.2%, respectively, for patients treated with 2D treatment (P = 0.002). The results of multivariate analysis showed that 3D-CRT, KPS, clinical tumor response and pretreatment hemoglobin level were independently associated with increased OS and CSS. No statistically significant differences were found between the radiation complications in the two groups.

CONCLUSIONSThe results of our study demonstrate that 3D-conformal radiotherapy improves the survival rate in patients with stage III NSCLC compared with that of 2D radiation therapy.

Objective To explore the clinical treatment efficacy of punch drainage combined with ventricle puncture in patients with senile hypertensive hemorrhage. Methods One hundred and sixty-eight patients with senile hypertensive hemorrhage, admitted to our hospital from March 2002 to February 2009, were treated by punch drainage combined with ventricle puncture and hematoma dissolution with urokinase. Meanwhile, follow-up for 6-12 months was performed to every patient; the postoperative treatment effects and complications were evaluated by Glasgow Outcome Scale; the relations between the prognosis and both the amount of intracerebral hemorrhage and grades of consciousness situation were statistically analyzed. Results Good prognosis was noted in 91 patients,mild disability in 41, severe disability and vegetative state in 13, and death in 23; few postoperative complications were noted. The prognoses were significantly different in patients with different amounts of intracerebral hemorrhage; so are those in patients with different grades of consciousness situation (P＜0.05); the prognosis of patients under grade Ⅰ-Ⅱ consciousness situation was better than that of patients under grade Ⅲ-Ⅳ consciousness situation and the prognosis of patients with hemorrhage between 30-70 mL was obviously better than that of patients with hemorrhage above 70 mL. Conclusion The punch drainage combined with ventricle puncture and hematoma dissolution with urokinase is an effective treatment method for patients with senile hypertensive intracerebral hematoma.

Objective To determine the survival rate of HIV/AIDS patients after receiving free antiretroviral treatment in Dehong prefecture, Yunnan province. Methods A retrospective cohort analysis was conducted on all the HIV/AIDS patients aged over 16 years who had started antiretroviral treatment during January 2007 throughout December 2009 in Dehong prefecture.Results A total of 3103 HIV/AIDS patients had received antiretroviral treatment during the study period. Among them, the mean age was (36.0 ± 9.9) years and 62.4% were males. 66.2% of them were infected with HIV through heterosexual transmission, and the mean treatment follow-up time was 21.7 months. Most patients well complied with the treatment, i.e., the average times of not taking the medicine were less than 5 per month. The cumulative survival rate of antiretroviral treatment after 1, 2, 3, 4, and 5 years were 0.95, 0.94, 0.93, 0.92, and 0.92, respectively. Data from the Cox proportional hazard regression model analysis indicated that, after adjustment for age, gender, and marital status, the baseline CD4+T cell counts and transmission route could significantly predicate the rates of survival. Those who were with baseline CD4+T cell counts as 200-350/mm3 were less likely to die of AIDS than those with CD4+T cell counts ＜200/mm3 (Hazard Ratio or HR=0.16, 95%CI:0.09-0.28), and HIV-infected through mother-to-child transmission or routes other than heterosexual transmission were less likely to die of AIDS than through injecting drug use (HR=0.35, 95% CI:0.13-1.00). Conclusion Free antiretroviral treatment had significantly improved the survival of HIV/AIDS patients. Earlier initiation of antiretroviral treatment was likely to have achieved better survival effects.

Objective To explore the clinical effects of stereotactic radiofrequency multitarget lesion on the treatment of senile dementia in patients with mental disorder. Methods Under the CT localization, 18 patients with mental retardation were treated by stereotactic surgery of multi-target lesion.Their therapeutic effects were evaluated by Scale and National Psychosurgery Cooperation Request on Modern Psychosurgery Operation Cure (protocol) in 1990. Results Postoperative follow-up was performed for 12-36 months; 9 patients progressed remarkably; 6 got improvement and only 3 showed no changes; the total effective rate was 83.3%. The scores of brief psychiatric rating scale, social disability screening schedule and scale for assessment of positive symptoms after the treatment were significantly lower than those before the treatment (P＜0.05). Mini-mental state examination showed no changes on the intelligence before and after the treatment (P＞0.05). Conclusion The stereotactic surgery of multi-targets lesion is an effective method in treating senile dementia in patients with mental disorder,with few complications and little influences on the intelligence.

OBJECTIVETo investigate the association between survival and postoperative three-dimensional conformal radiotherapy (3DCRT) in patients with resected non-small cell lung cancer (NSCLC).

METHODSEighty-four patients were treated with surgery and postoperative 3DCRT for NSCLC. Sixty-five (77.4%) patients received lobectomy, and 19 (22.6%) received pneumonectomy. Fifty-four (64.3%) patients achieved R0 resection and 30 cases (35.8%) received R1/R2 resection. Fifty-two patients were of stage IIIA and 24 patients were of stage IIIB. Photon energy of 6 MV was used for all the patients. The median 3DCRT dose was 60 Gy (40 - 70 Gy) with a fraction size of 2 Gy. Thirty-seven patients received median 3 cycles of adjuvant chemotherapy. The median follow-up was 35.5 months for survivors.

RESULTSThe overall 3-year survival rate was 58.6%, and the 4-year overall survival rate was 43.9%. Of the 43 patients who had treatment failure, only 8 (9.9%) patients showed intrathoracic recurrence, but 38 (46.9%) patients had distant metastasis. The univariate analysis for all patients showed that sex, age, weight loss, tumor size, pathology and stage were not correlated with prognosis. R1/R2 resection was associated with a significantly worse survival. Toxicities were acceptable, with 9 (11.1%) patients appeared higher than NCI CTC grade 2 radiation pneumonitis.

CONCLUSIONIn a population-based cohort, postoperative 3DCRT for NSCLC provides a good prognosis, and the radiation-related pneumonitis is acceptable.

OBJECTIVETo summarize our experience and evaluate the prognostic factors of locally advanced non small cell lung cancer (LA-NSCLC) treated with three dimentional conformal radiotherapy (3D-CRT).

METHODS118 patients with stage IIImA/IIIB non small cell lung cancer were treated with 3D-CRT from Nov. 2001 to Mar. 2005. 113 patients with complete clinical data were eligible for analysis, 45 of them received radiotherapy alone; 39 were treated by concurrent chemoradiation with paclitaxol plus carboplatin in 32 patients and topotecan in 7 patients, and 29 by sequential chemoradiation with platinum-based regiment in most of them. The dose of radiation for the thoracic field ranged from 26 Gy to 75 Gy with a median dose of 60 Gy. GTV and PTV were collected from the 3D treatment plans in 79 and 101 patients, respectively. Overall survival (OS) was calculated using the Kaplan-Meier method. Comparisons among the curves were made using a two-tailed long-rank test. The Cox model was used for multivariate analysis.

RESULTSThe 1-, 2- and 3-year overall survival rate was 60.7%, 31.6% and 22.4%, respectively, with a median survival time of 17 months. In univariate analysis, the following characteristics were significantly associated with longer survival: absence of chest pain, good karnofsky performance status (KPS), albumin > 4.2 g/L, hemoglobin > or = 140 g/L (male) or 130 g/L (female), response to radiotherapy and GTV < 100 cm3. However, multivariate analysis revealed that only good KPS was an independent risk factor predicting the survival.

CONCLUSIONThree-dimensional conformal radiotherapy is effective in the treatment of locally advanced non-small cell lung cancer with acceptable complications. Karnofsky performance status is the only independent prognositic factor.
