AIM: To explore the efficacy of preoperative intravitreal injection of conbercept combined with 25G+ pars plana vitrectomy(PPV)in the treatment of proliferative diabetic retinopathy(PDR).METHODS: The clinical data of 154 patients(176 eyes)with PDR admitted to our hospital from January 2019 to June 2021 were collected for retrospective analysis. According to the treatment methods, 80 patients(92 eyes)in combined treatment group were treated with preoperative intravitreal injection of conbercept combined with 25G+PPV, and 74 patients(84 eyes)in control group were given 25G+PPV only. The postoperative clinical efficacy and levels of adipokines [adiponectin(APN), retinol binding protein 4(RBP4)] before and after surgery were compared between both groups of patients.RESULTS: The combined treatment group showed better clinical efficacy than the control group at 1mo after surgery(P<0.05). Both groups had lower RBP4 levels at 3mo after surgery(P<0.05), with the combined treatment group showing a lower level than the control group(P<0.05). Serum APN levels significantly increased in both groups after surgery(P<0.05), with the combined treatment group having a higher level than the control group(P<0.05). The combined treatment group had lower incidence rates of retinal proliferation and postoperative complications after than the control group 3mo of follow-up(P<0.05).CONCLUSION: Preoperative intravitreal injection of conbercept combined with 25G+PPV is beneficial in improving the therapeutic effect of PDR and reducing the incidence rates of complications, which may be related to the regulations of the expressions of adipokines.

Exposure level of neonicotinoid pesticides and their metabolites in pregnant women in the suburb of Shanghai / 中华预防医学杂志

In 2021, a total of 151 pregnant women were selected from the suburb of Shanghai. A questionnaire survey was conducted to obtain data about maternal age, gestational week, total annual household income, education level and passive smoking among pregnant women and one spot urine was collected. The concentrations of eight neonicotinoid pesticides and four metabolites in urine were measured by ultra-high performance liquid chromatography-tandem quadrupole time-of-flight mass spectrometry. The differences in detection frequencies and concentrations of neonicotinoid pesticides and their metabolites among pregnant women with different characteristics were compared, and the influencing factors of the detection of neonicotinoid pesticides in urine were analyzed. The results showed that at least one neonicotinoid pesticide was detected in 93.4% (141 samples) of urine samples. The detection frequencies of N-desmethyl-acetamiprid, clothianidin, thiamethoxam, and N-desmethyl-clothianidin were high, about 78.1% (118 samples), 75.5% (114 samples), 68.9% (104 samples), and 44.4% (67 samples), respectively. The median concentration of the sum of all neonicotinoid pesticides was 2.66 μg/g. N-desmethyl-acetamiprid had the highest detection concentration with a median concentration of 1.04 μg/g. A lower urinary detection frequency of imidacloprid and its metabolites was seen in pregnant women aged 30-44 years [OR (95%CI): 0.23 (0.07-0.77)]. A higher detection frequency of clothianidin and its metabolites was seen in pregnant women with per capita annual household income≥100 000 yuan [OR (95%CI): 6.15 (1.56-24.28)]. There was widespread exposure to neonicotinoid pesticides and their metabolites in pregnant women from the suburb of Shanghai, which might pose potential health risks to pregnant women, and maternal age and household income were potential influencing factors of the exposure to neonicotinoid pesticides.

There was no significant difference in the incidence rate of adverse reactions between the two groups (OR=1.28, 95%CI: 0.85-1.92, P=0.24).@*CONCLUSIONS@#The addition of rituximab to the treatment regimen for children and adolescents with mature B-cell non-Hodgkin's lymphoma can bring significant survival benefits without increasing the incidence of adverse reactions.

Efficacy of partial nephrectomy in patients with localized renal carcinoma: a 20-year experience of 2 046 patients in a single center / 中华外科杂志

Objectives: To analyze the long-term survival of patients with localized renal cell carcinoma after partical nephrectomy. Methods: The clinicopathological records and survival follow-up data of 2 046 patients with localized renal cell carcinoma, who were treated with partial nephrectomy from August 2001 to February 2021 in the Department of Urology, Sun Yat-sen University Cancer Center, were retrospectively analyzed. There were 1 402 males and 644 females, aged (M(IQR)) 51 (19) years (range: 6 to 86 years). The primary end point of this study was cancer-specific survival. Survival curves were estimated using the Kaplan-Meier method, and the difference test was performed by Log-rank test. Univariate and multivariate Cox analysis were fitted to determine factors associated with cancer-specific survival. Results: The follow-up time was 49.2 (48.0) months (range: 1 to 229 months), with 1 974 patients surviving and 72 dying. The median cancer-specific survival time has not yet been reached. The 5- and 10-year cancer specific survival rates were 97.0% and 91.2%, respectively. The 10-year cancer-specific survival rates for stage pT1a (n=1 447), pT1b (n=523) and pT2 (n=58) were 95.3%, 81.8%, and 81.7%, respectively. The 10-year cancer-specific survival rates of patients with nuclear grade 1 (n=226), 2 (n=1 244) and 3 to 4 (n=278) were 96.6%, 89.4%, and 85.5%, respectively. There were no significant differences in 5-year cancer-specific survival rates among patients underwent open, laparoscopic, or robotic surgery (96.7% vs. 97.1% vs. 97.5%, P=0.600). Multivariate analysis showed that age≥50 years (HR=3.93, 95%CI: 1.82 to 8.47, P<0.01), T stage (T1b vs. T1a: HR=3.31, 95%CI: 1.83 to 5.99, P<0.01; T2+T3 vs. T1a: HR=2.88, 95%CI: 1.00 to 8.28, P=0.049) and nuclear grade (G3 to 4 vs. G1: HR=2.81, 95%CI: 1.01 to 7.82, P=0.048) were independent prognostic factors of localized renal cell carcinoma after partial nephrectomy. Conclusions: The long-term cancer-specific survival rates of patients with localized renal cancer after partial nephrectomy are satisfactory. The type of operation (open, laparoscopic, or robotic) has no significant effect on survival. However, patients with older age, higher nuclear grade, and higher T stage have a lower cancer-specific survival rate. Grasping surgical indications, attaching importance to preoperative evaluation, perioperative management, and postoperative follow-up, could benefit achieving satisfactory long-term survival.

Clinical diagnosis and treatment of multiple pulmonary nodules / 中华肿瘤杂志

CT screening has markedly reduced the lung cancer mortality in high-risk population and increased the detection of early-stage pulmonary neoplasms, including multiple pulmonary nodules, especially those with a ground-glass appearance on CT. Multiple primary lung cancer (MPLC) constitutes a specific subtype of lung cancer with indolent biological behaviors, which is predominantly early-stage adenocarcinoma. Although MPLC progresses slowly with rare lymphatic metastasis, existence of synchronous lesions and distributed location of these nodules still pose difficulty for the management of such patients. One single operation is usually insufficient to eradicate all neoplastic lesions, whereas repeated surgical procedures bring about another dilemma: whether clinical benefits of surgical treatment outweigh loss of pulmonary function following multiple operations. Therefore, despite the anxiety for treatment among MPLC patients, whether and how to treat the patient should be assessed meticulously. Currently there is a heated discussion upon the timing of clinical intervention, operation mode and the application of local therapy in MPLC. Based on clinical experience of our multiple disciplinary team, we have summarized and commented on the evaluation, surgical treatment, non-surgical local treatment, targeted therapy and immunotherapy of MPLC in this article to provide further insight into this field.

The relationship among pubertal timing, overweight and obesity and eating disorders in adolescents / 中国学校卫生

Objective@#To understand the relationship among pubertal timing, overweight and obesity, and eating disorders among Bengbu adolescents, and to provide a reference for obesity prevention.@*Methods@#Two nine year schools were conveniently selected in Bengbu, with 683 students from grade 5 to grade 8. Puberty Development Scale (PDS) and Eating Disorders Inventory of Children (EDI-C) subscale were used, height and weight were measured. The associations between obesity, pubertal timing and eating disorders were analyzed.@*Results@#The prevalence of overweight and obesity was higher in boys than that in girls, and the rate of early pubertal timing, drive for thinness score, body dissatisfaction score and total eating disorder score were higher in girls than that in boys( χ 2/t =28.69, 57.99, 3.47, 2.59, 3.30, P <0.05). The differences in rate of overweight and obesity, bulimia score and total eating disorder score were statistically significant by grade( χ 2/F =28.39, 5.11, 3.95, P ＜0.01). There was a positive correlation among overweight obesity and early pubertal timing and eating disorder, and a positive correlation between early pubertal timing and eating disorder( r =0.18, 0.17, 0.14, P < 0.01 ). The mediating effect of early pubertal timing between overweiht, obesity and eating disorders partially contributed 14.25% to the total effect.@*Conclusion@#Overweight and obesity is associated with eating disorders, and early pubertal timing partially mediate the association between overweight obesity and eating disorders. Healthy lifestyle should be advocated in family and school to effectively prevent adolescents obesity, pubertal timing, and eating disorders.

Objective:To investigate the efficacy of different treatment modes for locoregional recurrence after nephrectomy in patients with renal cell carcinoma.Methods:A total of 106 patients with locoregional recurrence after nephrectomy without distant metastasis (77 males and 29 females) admitted to Sun Yat-sen University Cancer Center from October 2001 to July 2020 were retrospectively analyzed. The median age was 51 (40, 60) years old. Radical nephrectomy was performed in 90 patients with primary tumor and partial nephrectomy was performed in 16 patients. Pathological diagnosis showed that 54 cases were clear cell carcinoma and 52 cases were non-clear cell carcinoma. 53 cases were in stage T 1-2 and 53 cases in stage T 3-4. The median diameter of recurrent lesions was 3.2 (2.0, 6.3) cm, and the median number was 2 (1, 4). The recurrence sites were divided into renal fossa recurrence (33 cases), renal fossa±retroperitoneal lymph node recurrence (38 cases), and intra-abdominal spread (35 cases). The median duration from primary surgery to local recurrence was 14.8 (7.3, 35.8) months. Two treatment groups were identified as systemic therapy alone (Group A) and local therapy with or without systemic therapy (Group B). The Kaplan-Meier method was used to compare the progression free survival (PFS) and overall survival (OS) between Group A and Group B. The Cox model was used to perform univariate and multivariate analysis. Results:Of all the 106 patients, 33 patients were in Group A and 73 patients were in Group B. In Group A, 29 patients (87.9%) received targeted therapy, and 4 patients (12.1%) received targeted therapy combined with immunotherapy. In Group B, 34 patients (46.6%) received surgery or ablation and 39 patients (53.4%) received SBRT, of which 62 patients (84.9%) received concurrent systemic therapy. Among them, 58 patients (93.5%) received targeted therapy, and 4 patients (6.5%) received targeted therapy combined with immunotherapy. The median follow-up period was 29.0 (15.4, 45.9) months, 64 patients progressed on tumor including 28 patients died. The median PFS and OS were 15.6 (7.1, 35.2) months and 66.9 (37.8, not reached) months. The median PFS of Group A and Group B were 7.6(5.0, 17.2)months and 22.2(9.6, 63.9)months respectively ( P=0.001), median OS of Group A and Group B were 45.7 (23.4, 62.8)months and 71.0(50.6, not reached)months respectively, and the 2-year OS were 70.6% and 85.5% in Group A and Group B respectively ( P=0.023). The univariate analysis showed local therapy with or without systemic therapy was significantly reduced 56% risk of tumor progression ( HR=0.44, P=0.003) and reduced 60% risk of death ( HR=0.40, P=0.028). The multivariate analysis showed that the OS was associated with ECOG score( HR=10.20, 95% CI 4.13-25.30, P<0.001)and local therapy( HR=0.23, 95% CI 0.09-0.58, P=0.002). Conclusion:Compared with systemic therapy alone, local therapy with or without systemic therapy can effectively improve the PFS and OS of patients with locoregional recurrence after nephrectomy.

A Comparative Study of Licochalcone A Moisturiser versus Topical Hydrocortisone in Treating Mild-to-Moderate Atopic Dermatitis

Background@#Topical corticosteroids are the mainstay of treatment for patients with atopic dermatitis. However, adverse effects associated with long-term steroid use often limit its use. This interventional study compared the efficacy of a proprietary moisturiser containing licochalcone A, omega-6 fatty acids, and ceramide 3 against 1% hydrocortisone cream in treating patients with mild-to-moderate atopic dermatitis.@*Methods@#Patients with mild-to-moderate atopic dermatitis affecting either the cubital fossa or popliteal fossa symmetrically were given twice-daily applications of the moisturiser and hydrocortisone on opposite sides of the body and monitored for a total of three weeks in a non-randomised half body, doubleblind study. Hydrocortisone was switched to aqueous cream after two weeks, whereas the application of the moisturiser continued until study completion. The assessment of SCORing Atopic Dermatitis (SCORAD) index and Dermatology Life Quality index was performed at baseline and every subsequent follow-up visit to measure patients’ response to treatment. @*Results@#The licochalcone A (LA) moisturiser and 1% hydrocortisone (HC) cream both demonstrated significant reduction in sign and symptom scores after only 1 week of treatment (percentage of reduction in sign and symptom scores: 52.8% [LA] vs 58.5% [HC]). Further reduction in mean sign and symptom scores for both treatments was observed at week 2 (61.3% [LA] vs 56.8% [HC]) and also at week 3 when HC was switched to aqueous cream (70.5% [LA] vs 63.5% [HC→aqueous cream]) (p<0.001 vs baseline within the same treatment arm at weeks 1, 2 and 3). When comparing the mean difference in SCORAD index for both individual as well as total skin signs and symptoms between LA and HC (i.e. inter-arm comparison), there was no significant difference between the two treatments for all the assessed parameters. Patients reported improvements in itching, sleeplessness, and overall quality of life over the course of treatment.@*Conclusion@#The licochalcone A moisturiser can be considered as an effective steroid-sparing alternative to topical corticosteroids in managing mild-to-moderate atopic dermatitis.

Baseline left ventricular ejection fraction associated with symptom improvements in both children and adolescents with postural tachycardia syndrome under metoprolol therapy / 中华医学杂志(英文版)

BACKGROUND@#Postural tachycardia syndrome (POTS) is a common childhood disease that seriously affects the patient's physical and mental health. This study aimed to investigate whether pre-treatment baseline left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) values were associated with symptom improvement after metoprolol therapy for children and adolescents with POTS.@*METHODS@#This retrospective study evaluated 51 children and adolescents with POTS who received metoprolol therapy at the Peking University First Hospital between November 2010 and July 2019. All patients had completed a standing test or basic head-up tilt test and cardiac echocardiography before treatment. Treatment response was evaluated 3 months after starting metoprolol therapy. The pre-treatment baseline LVEF and LVFS values were evaluated for correlations with decreases in the symptom score after treatment (ΔSS). Multivariable analysis was performed using factors with a P value of  0.050). However, responders had significantly higher baseline LVEF (71.09% ± 4.44% vs. 67.17% ± 4.88%, t = -2.789, P = 0.008) and LVFS values (40.00 [38.00, 42.00]% vs. 36.79% ± 4.11%, Z = -2.542, P = 0.010) than the non-responders. The baseline LVEF and LVFS were positively correlated with ΔSS (r = 0.378, P = 0.006; r = 0.363, P = 0.009), respectively. Logistic regression analysis revealed that LVEF was independently associated with the response to metoprolol therapy in children and adolescents with POTS (odds ratio: 1.201, 95% confidence interval: 1.039-1.387, P = 0.013).@*CONCLUSIONS@#Pre-treatment baseline LVEF was associated with symptom improvement after metoprolol treatment for children and adolescents with POTS.

Changes in neuronal structure of rat hippocampal CA1 area were observed by hematoxylin-eosin （HE） staining， and the neuronal apoptosis in hippocampus by terminal deoxynucleotidyl transferase （TdT）-mediated dUTP nick end labeling （TUNEL） staining. Western blot assay was used to detect the expression levels of glial fibrillary acidic protein （GFAP）， ionized calcium-binding adapter molecule 1 （Iba-1）， phosphorylated p38 mitogen-activated protein kinase （p38 MAPK）， and phosphorylated nuclear factor <italic>κ</italic>B （NF-<italic>κ</italic>B）， followed by the measurement of interleukin-1<italic>β</italic> （IL-1<italic>β</italic>） and tumor necrosis factor-<italic>α</italic> （TNF-<italic>α</italic>） in the brain by enzyme-linked immunosorbent assay （ELISA）. Result:Compared with the sham operation group， the model group displayed obviously decreased spatial learning and memory ability and memory retention ability （<italic>P</italic><0.05， <italic>P</italic><0.01）， neuronal damage in hippocampal CA1 area， enhanced neuronal apoptosis （<italic>P</italic><0.01）， up-regulated GFAP and Iba-1 （<italic>P</italic><0.01）， elevated phosphorylation of p38 MAPK and NF-<italic>κ</italic>B （<italic>P</italic><0.01）， and increased IL-1<italic>β</italic> and TNF-<italic>α</italic> （<italic>P</italic><0.01）. Compared with the model group， NC at each dose significantly improved the spatial learning and memory ability and memory retention ability of VCI rats （<italic>P</italic><0.05， <italic>P</italic><0.01）， ameliorated the neuronal damage in hippocampus CA1 area， reduced the apoptosis rate of nerve cells （<italic>P</italic><0.05， <italic>P</italic><0.01）， down-regulated the expression of GFAP and Iba-1 （<italic>P</italic><0.01）， decreased the phosphorylation levels of p38 MAPK and NF-<italic>κ</italic>B （<italic>P</italic><0.05， <italic>P</italic><0.01）， and lowered TNF-<italic>α</italic> and IL-1<italic>β</italic> levels （<italic>P</italic><0.01）. Conclusion:NC alleviates the inflammatory damage of the central nervous system caused by activated p38 MAPK and NF-<italic>κ</italic>B and improves chronic cerebral hypoperfusion-induced VCI in rats by inhibiting the activation of microglia and astrocytes.

Pollution， human exposure and harmful effects of neonicotinoid pesticides / 上海预防医学

Neonicotinoid is a kind of neuroactive pesticide， and it has become the most widely used pesticide in the world. In recent years， neonicotinoid has been detected in the environment and food， suggesting that human can be exposed to this kind of pesticide through drinking water， ingestion and respiration， which poses potential health hazards to human. However， there is no comprehensive report on the pollution level of neonicotinoid pesticides in the environment and food and the impact on human health. In this paper， the pollution status， population exposure level and potential health risks of neonicotinoid pesticides in water， air and food were reviewed. We found that neonicotinoid residues are widespread in fruits and vegetables， of which imidacloprid has the highest detection rate. Except for a few samples with excessive neonicotinoid detection， the detection level in most samples did not exceed national food safety standards. A variety of neonicotinoid pesticides have been detected in the air， surface water， tap water and drinking water. External exposure studies in the population have shown that ingestion is the main route of exposure to neonicotinoid， and the external exposure level is much lower than its chronic reference dose. The internal exposure study mainly detected the concentration of neonicotinoid pesticides and their metabolites in urine. A variety of neonicotinoid pesticides and their metabolites are detected in urine， and the concentration range is ng/ml level. Internal exposure studies found that the detection rate of thiamethoxam and dinotefuran in urine is higher， and the detection rate of neonicotinoid in Asian countries is higher than that in European and American countries. Occupational exposure studies found that neonicotinoid exposure levels increased after pesticide spraying， and the exposure levels in rural areas where pesticides were commonly used were higher than those in neighboring urban areas. Animal experiments have found that neonicotinoid pesticides have reproductive toxicity， genetic toxicity， neurotoxicity， immunotoxicity， liver toxicity and nephrotoxicity to non-target organisms. Cell experiments suggest that neonicotinoid is an endocrine disruptor. The symptoms of acute exposure in humans are related to the exposure dose， route and physical condition of the exposed person， which ranges from mild symptoms （nausea， vomiting， headache and diarrhea） to death. Population epidemiological studies have shown that chronic exposure to neonicotinoid pesticides is associated with adverse health effects in humans such as neonatal tetralogy of Fallot， anencephaly， and adverse mental symptoms.

Preliminary clinical observation of efficacy and safety of stereotactic body radiation therapy in combination with targeted therapy for metastatic renal cell carcinoma / 中华放射肿瘤学杂志

Objective:To evaluate the preliminary clinical efficacy and safety of stereotactic body radiation therapy (SBRT) in combination with targeted therapy for metastatic renal cell carcinoma (mRCC).Methods:Clinical data of 58 patients with mRCC who were treated with SBRT in combination with targeted therapy in Sun Yat-sen University Cancer Center from June 2013 to December 2018 were retrospectively analyzed. Among them, 79.3% patients were classified as intermediate or high risk according to International Metastatic Renal Cell Carcinoma Database Consortium Criteria. The median biologically equivalent dose (BED) was 147 Gy (67 to 238 Gy).Results:Overall, 32, 13, 7, 5 and 1 patients received SBRT for 1, 2, 3, 4 and 6 metastatic sites (105 lesions) and 71.4% of them were bone lesions. Targeted therapy was continued during SBRT. With a median follow-up of 9.4 months (range 2.7 to 40.1 months), 18 patients died. The 1-year local control rate was 97.4%. The 1-year progression-free survival was 50.3%. The 1-and 2-year overall survival was 72% and 53%. Approximately 85% patients experienced pain relief after SBRT. Patients who achieved complete or partial response after SBRT obtained better overall survival than those with stable disease or disease progression (1-year overall survival: 83% vs. 48%, P=0.021). In the whole cohort, 6 cases developed Grade Ⅲ adverse events, 4 of which were Grade Ⅲ myelosuppression, 1 case of Grade Ⅲ neuropathy and 1 case of radiation-induced skin injury. Conclusion:Preliminary study reveals that combined use of targeted therapy and SBRT is an efficacious and safe treatment of advanced mRCC.

Effect of Chinese reading aloud training on cognitive function in patients with vascular cognitive impairment no dementia / 中华行为医学与脑科学杂志

Objective:To investigate the effect of Chinese reading aloud training (c-RAT) on cognitive function and activities of daily living in patients with vascular cognitive impairment no dementia (VCIND).Methods:From January 2018 to January 2019, totally 80 patients with VCIND in the General Hospital of Xingtai Mining Group were enrolled.Subjects were randomized grouped into c-RAT group ( n=43) and control group ( n=37). The c-RAT group was asked to read aloud the Chinese paper for 5 days a week for 12 weeks.At the time of enrollment and 12 weeks after the intervention, the Montreal cognitive assessment (MoCA), trail making test (TMT), auditory verb learn test (AVLT), digit symbol substitution test (DSST) and modified Barthel index (MBI) were filled out. Results:Compared with control group, the difference of D-value in c-RAT group was statistically significant in MoCA total scores(4.00(2.00), 1.50(0.50), Z=3.012, P=0.003), scores of MoCA-Visual space execution (2.00(1.00), 0.00(2.00), Z=2.787, P=0.008), MoCA-attention (1.00(1.00), 0.00(0.50), Z=2.369, P=0.022), MoCA-language (1.00(1.00), 0.00(0.75), Z=3.049, P=0.000)and MoCA-delayed recall(2.00(2.00), 0.00(1.00), Z=2.043, P=0.014), TMT-A scores (-8.00(23.00), 10.50(30.25), Z=2.120, P=0.039), AVLT scores (1earning)(3.00(2.00), 0.50(0.75), Z=2.266, P=0.039) , AVLT scores (recall)(2.00(1.00), 0.00(1.00), Z=2.974, P=0.003)、AVLT scores (recognition) (2.00(0.00), 0.50(1.50), Z=3.054, P=0.000)and DSST scores ((4.96±0.71), (2.39±0.78), t=2.572, P=0.014), while there were no significant differences in the rest parts of MoCA, TMT-B and MBI( P>0.05). The increased scores in DSST were positively correlated ( r=0.205, P=0.006) with the number of reading aloud tasks finished. Conclusion:C-RAT can improve general cognition, especially in information processing speed, executive function, attention and auditory memory.
