ABSTRACT

Photothermal therapy (PTT) is a highly effective anti-tumor method. However, when laser radiation was used to ablate tumors, it usually triggers a series of inflammatory reactions, promoting the further development of tumors and affecting the effect of anti-tumor therapy. Therefore, it is an effective method to improve the anti-tumor effect by suppressing the inflammatory response through the precise targeted delivery of anti-inflammatory drug while realizing the photothermal treatment of tumors. To this end, the redox-responsive linker 3,3'-dithiodipropionic acid was used to bond the classic hydrophobic anti-inflammatory drug 18β-glycyrrhetinic acid (18β-GA) and the hydrophilic fragment methoxy-polyethylene glycol (mPEG-NH2) to obtain redox-responsive amphiphilic polymer PEG-DA-GA in this study. Then, photothermal agent IR-780 was encapsulated to prepare redox-responsive polymer micelle PDG/IR-780 NPs. The PDG/IR-780 NPs exhibited uniform particle size of 80.2 ± 5.3 nm and the polydispersity index (PDI) was 0.215 ± 0.079. All animal experiments followed the ethical requirements formulated by the Ethics Committee of Sichuan University. The results showed that PDG/IR-780 NPs could respond to the abundant glutathione (GSH) in tumor cells to promote the disintegration of nanoparticle and the release of 18β-GA, thus significantly improved the killing efficiency on 4T1 cells, when compared with the non-redox-responsive control PSG/IR-780 NPs. When the concentration of 18β-GA was 50 μg·mL-1, the cell viability of 4T1 cells in the PDG/IR-780 NPs group was only (19.29 ± 1.80) %, which was significantly lower than the result of in PSG/IR-780 NPs group (29.30 ± 1.37) %. The results of frozen sections of tumor tissues showed that the designed PDG NPs can promote the tumor-targeted distribution of drugs compared with the free drug group. Eventually, PDG/IR-780 NPs achieved wonderful anti-tumor efficacy on 4T1 triple-negative breast cancer model, revealing the new possibility of the combined therapy strategy of photothermal and anti-inflammatory therapy.

ABSTRACT

Objective@#This study aimed to analyze the temporal trends and characteristics associated with waist circumference (WC) among elderly Chinese people.@*Methods@#We used data from 3,096 adults ≥ 65 years who participated in the China Health and Nutrition Survey (CHNS), an ongoing cohort study, between 1993 and 2015. We used longitudinal quantile regression models to explore the temporal trends and characteristics associated with WC.@*Results@#WC increased gradually among the elderly Chinese population during the survey. The WC curves shifted to the right with wider distributions and lower peaks in men and women. All WC percentile curves shifted upward with similar growth rates in the 25th, 50th, and 75th percentiles. The WC means increased from 78 cm to 86 cm during the 22 years of our study. WC significantly increased with age and body mass index and decreased with physical activity (PA). These associations were stronger in the higher percentiles than in the lower percentiles.@*Conclusions@#WC is rising among Chinese adults ≥ 65 years. Factors affecting WC in elderly people may have different effects on different percentiles of the WC distribution, and PA was the most important protective factor in the higher percentiles of the WC distribution. Thus, different interventional strategies are needed.

ABSTRACT

This article aims to comprehensively review the concept, etiology, classification, classical cortical mapping, assessment, a proposed flowchart for the diagnosis and differential diagnosis, treatment, rehabilitation, mechanisms of development and recovery, prognosis, and influencing factors for post-stroke aphasia(PSA)types in the Chinese language.We emphasize the necessity and significance of neuroimaging assessment of the brain and blood vessels and neuropsychological assessment in the diagnosis and differential diagnosis of PSA in Chinese.We also recommend and encourage the use of the dichotomies of internal vs.external and anterior vs.posterior as a starting point, based on the association of anatomical locations of the brain and blood vessels with brain language areas and language disorders.A classification system of PSA in Chinese developed from this approach in the form of a flowchart is well-suited for guiding the clinical treatment of cerebral stroke.Incorporating the "four elements" , the flowchart enables convenient diagnosis, classification and differential diagnosis of PSA in Chinese and facilitates targeted and personalized rehabilitation planning to benefit the patient.This article introduces the use of memantine, piracetam, donepezil and other drugs for PSA treatment, evaluates clinical trials on memantine conducted in China and abroad and its mechanisms of action for the treatment of PSA, and discusses how rehabilitation therapy achieves therapeutic effects.For the treatment of PSA, clinical research and practice using drugs such as memantine, piracetam and donepezil in combination with non-pharmacotherapy and rehabilitation training should be promoted.

ABSTRACT

Objective@#This study aimed to determine the independent and joint associations of sedentary time (ST) and physical activity (PA) with metabolic syndrome (MetS) and its components among Chinese adults.@*Methods@#The study analyzed data from 4,865 adults aged ≥ 18 years who participated in the 2009 and 2015 China Health and Nutrition Surveys (CHNS). Four types of leisure ST and three types of PA self-reported at baseline were collected. Multivariable logistic regressions were used to determine the independent and joint associations of ST and PA with the odds of MetS or its components.@*Results@#For independent effects, higher levels of television time and total leisure ST was associated with higher MetS risk [odds ratio ( @*Conclusions@#MVPA and total PA have independent preventive effects, and sedentary behavior (mainly watching TV) has an unsafe effect on MetS and its components. Strengthening the participation of MVPA and combining the LPA to replace the TV-based ST to increase the total PA may be necessary to reduce the prevalence of MetS in Chinese adults.

ABSTRACT

Spinocerebellar ataxias (SCAs), formerly known as autosomal dominant cerebellar ataxia, are a group of hereditary heterogeneous neurodegenerative disease that contains many subtypes. Spinocerebellar ataxia type 23 (SCA23), one type of SCAs, is caused by mutant prodynorphin (PDYN) gene. A 22-year-old patient was diagnosed with sporadic SCA23 due to gene detection, with a novel identified mutation, PDYN c.647C>T (p.P216L). Located in the dynorphin A-coding-region of PDYN gene, the pathogenic mechanism of the mutation may be relevant to the pathological changes caused by the variant including neurological dysfunction and death of cells. Mild improvement with the patient has been witnessed after active balance and speaking exercise.

ABSTRACT

Objective: Explore the usage of anti-hypertension drugs and the rationality of hypertension prescription among the primary health centers in Dongcheng District, Beijing. Method: This cross-sectional and retrospective study was applied to analyze the hypertension prescriptions from the 8 community health centers in Dongcheng District. The anatomical, therapeutic and chemical classification (ATC) codes were used to determine the drug category. ATC information was used to filter data containing antihypertensive drugs, and group the number and proportion of ATC categories. The type of drug was judged by its generic name. According to the diagnosis information in the prescription, the prescription containing the Western medicine diagnosis of hypertension was screened out. The comorbidities of hypertension in the study included 7 types of diseases including diabetes, chronic kidney disease, coronary heart disease, heart failure, atrial fibrillation, stroke, and dyslipidemia. The analysis of prescription rationality included rationality of combination medication, rationality of drug dosage and rationality of drug price. The agreed daily dose (DDD) method was used to analyze the rationality of drug dosage. The drug utilization index (DUI) was used as a quantitative indicator to estimate the rationality of medication, and overdose was expressed by DUI>1. The reasonableness of the drug price was judged based on the price of the drug and whether it was a drug in the "4+7" plan. Results: A total of 658 140 prescriptions were extracted as the final data set, involving 7 categories and 60 commonly used anti-hypertensive drugs, and the corresponding cost of medication was ¥96.58 million. Drugs were prescribed according to comorbidities, and the choice followed the international guidelines. Calcium channel blockers (CCB) were the most prescribed drugs in the prescriptions of patients with comorbidities, and α-adrenergic receptor antagonists were the least prescribed drugs. The proportion of diuretics prescribed in hypertensive patients complicating with heart failure was 21.17% (505/2 385), which was much higher than that of patients complicating with other comorbidities (P<0.05). The proportion of diuretics prescribed in hypertension patients complicating with dyslipidemia was lower than that of patients with other comorbidities (2 639 (0.94%), P<0.05), and β-blockers (BB) or angiotensin Ⅱreceptor blockers (ARB) were more likely to be selected (BB: 59 348 (21.08%), ARB: 51 356 (18.24%))in these patients. The proportion of BB in prescriptions for hypertension patients with chronic kidney disease was lower than that of patients with other comorbidities (P<0.05). The proportion of BB in prescriptions for hypertension patients with coronary heart disease was higher than that of other comorbidities (P<0.05). Hypertension patients with atrial fibrillation or stroke accounted for a higher proportion of CCB prescriptions (P<0.05). Single antihypertensive drug prescriptions accounted for the highest proportion, 61.19% (402 745/658 140). Two-combination prescriptions accounted for the highest proportion of combination prescriptions, 72.19% (184 392/255 395). CCB based two-combination prescriptions accounted for the highest proportion, 122 350(66.36%). ARB-based tri-combination prescriptions accounted for the highest proportion, 48 915(89.50%),followed by CCB based tri-combination prescriptions (44 732(81.85%)).There were 2 174 (0.33%) prescriptions with unreasonable combination therapies and DUI>1 were found in 48 out of 60 commonly used drugs. In all possible antihypertensive drugs, only 40.92% (109 227/266 993)followed the "4+7" plan. Conclusions: The anti-hypertensive agents from these prescriptions in the primary health centers are diverse, and the choice is generally complied with the guidelines, but some unreasonable situations existed, especially on the combined anti-hypertensive medication, overdose, and"4+7"plan is not followed completely.

ABSTRACT

To obtain the difference of the fungal and bacterial community diversity between wild Cordyceps sinensis, artificial C. sinensis and their habitat soil, Illmina Hiseq high-throughput sequencing technology was applied. The results show that Proteobacteria was the dominant bacterial phylum in C. sinensis, Actinobacteria was the dominant bacterial phylum in soil microhabitat, Ophiocordyceps sinensis was the predominant dominant fungus of C. sinensis. The α diversity analysis showed that the fungal diversity of stroma was lower than other parts, and the fungal diversity of wild C. sinensis was lower than that of artificial C. sinensis. The β diversity analysis showed that the fungal and bacterial community diversity of soil microhabitat samples was significantly different from that of C. sinensis. The fungal community diversity was less different between wild and artificial C. sinensis, especially in sclerotia. LEfSe analysis showed a lot of species diversity between wild and artificial C. sinensis. Those different species between wild C. sinensis, artificial C. sinensis and their habitat soil provide ideas for further research on breed and components of C. sinensis.

ABSTRACT

Objective:To summarize the clinical features and pathological changes of peripheral tissues from patients with neuronal intranuclear inclusion disease (NIID) diagnosed by genetic tests.Methods:Repeat-primed polymerase chain reaction was used to confirm the GGC repeated expansion in the 5′ untranslated region of the NOTCH2NLC gene in patients with suspected NIID who had visited the Department of Neurology of Peking University First Hospital from January 2018 to February 2020. The clinical data and pathological changes of peripheral tissues from patients with genetically diagnosed NIID were collected retrospectively and analysed. Immunostaining with anti-p62 and anti-ubiquitin antibody was performed on peripheral biopsy specimens.Results:Totally nine patients with NIID who had GGC repeated expansion in the NOTCH2NLC gene were found. Five patients were familial (from three faimilies), and four patients were sporadic. The age of onset was 36-61(51.33±7.12) years. The most common symptoms in this NIID group were episodic emotion and personality change (8/9), paroxysmal disturbance of consciousness (6/9) and intermitant head discomfort (6/9). Other symptoms included cognitive dysfunction, limb weakness, limb sensory disturbance, bladder dysfunction, ataxia, seizures and psychiatric symptoms. Brain magnetic resonance imaging showed high signals along the corticomedullary junction on diffusion-weighted image in eight out of nine patients. Skin biopsied samples from nine patients demonstrated the presence of eosinophilic intranuclear inclusions (IIs), appearing in the nucleus of fibroblasts, fat cells and ductal epithelial cells of sweat glands on hematoxylin-eosin staining. IIs were positive on anti-p62 and anti-ubiquitin immunostaining. Electron microscopy indicated the IIs were composed of a pile of filament materials without membrane. Muscle biopsies from two patients showed no obvious neurogenic or myogenic pathologic changes, except in one patient several rimmed vacuoles fibers were found. In one patient sural nerve biopsy showed severe demyelinating pathological changes. No IIs were found in the muscles and peripheral nerve tissue either by histological examination or by immunohistochemical staining with anti-p62 or anti-ubiquitin, while IIs were found by immunofluorescence staining with both anti-p62 and anti-ubiquitin in three patient′s tissue. Conclusions:The phenotype of this NIID patient group is adult-onset NIID, with episodic encephalopathy as the main clinical manifestation. Skin biopsy has high pathological diagnostic value for NIID. The immunofluorescence staining with anti-p62 and anti-ubiquitin is easier to detect the presence of IIs than histological staining and immumohistochemical staining.

ABSTRACT

Objective:To understand the vancomycin dose, therapeutic drug monitoring(TDM) situation and therapeutic effect of children after liver transplantation.Methods:A retrospective analysis of the data of 98 children who received intravenous vancomycin treatment after liver transplantation were conducted in the Department of Critical Care Medicine of Beijing Friendship Hospital from January 2017 to June 2019, including demographic data, vancomycin dose, serum trough concentration, drug-related adverse reactions and clinical outcome data.Results:A total of 98 children received intravenous vancomycin treatment and at least one steady-state TDM blood sample was collected.Among them, 53 cases (54.1%) were male, and the median age was 9 months(5 months to 14 years old). The median first daily dose of vancomycin treatment was 50(30-60)mg/(kg·d), and the median duration of treatment was 14(3-54)days.Only 27.5%(27/98)of the children′s initial trough concentration reached the target concentration (10-20 mg/L), while 26 cases(26.5%) did not reach the target after adjusting the treatment.Six children(6.1%)had renal toxicity caused by vancomycin, and two children had skin rash.The effective treatment rate accounted for 51.7%(15/29). The initial trough concentrations of vancomycin in the effective and ineffective groups were(5.92±3.82)mg/L and(10.43±5.37)mg/L, respectively.The difference was statistically significant ( P=0.041). Conclusion:The rate of intravenous vancomycin in children after liver transplantation is low, and the dose needs to be adjusted individually.

ABSTRACT

Objective: To observe the clinical efficacy of mind-refreshing and balance-restoring needling method combined with Frenkel exercises in treating ataxia after cerebral stroke. Methods: The recruited 120 patients were randomized into an observation group and a control group, with 60 cases in each group. The control group was intervened by mind-refreshing and balance-restoring needling method, while the observation group was given additional lower-limb Frenkel exercises. Before and after treatment and at the follow-up, the ataxic lower-limb function was scored using Berg balance scale (BBS) and international cooperative ataxia rating scale (ICARS), and Barthel index (BI) was adopted to score the activities of daily living (ADL). Results: After treatment, the markedly effective rate was 70.2% and the total effective rate was 96.5% in the observation group, versus 39.7% and 87.9% in the control group, and the differences in the markedly effective rate and the total effective rate were statistically significant (P<0.01, P<0.05). The intra-group comparisons showed that the BBS, ICARS and BI scores after treatment and at the follow-up were significantly different from those before treatment in both groups (all P<0.01).There were significant differences in the BBS score between the two groups after treatment and at the follow-up (P<0.05, P<0.01); the between-group differences in the ICARS and BI scores were statistically insignificant after treatment (both P>0.05), while the between-group differences in the ICARS and BI scores were statistically significant at the follow-up (both P<0.05). The interaction effects between the scoring time of BBS and BI and the group factor were statistically significant (P<0.01, P<0.05). Conclusion: Mind-refreshing and balance-restoring needling can effectively improve the lower-limb ataxic symptoms and ADL after stroke; when combined with Fenkel exercises, this needling method can produce more significant efficacy.

ABSTRACT

One hundred and nine consecutive coronary heart disease (CHD) patients with obstructive sleep apnea (OSA) undergoing percutaneous coronary intervention (PCI) during February 2016 to August 2018 were enrolled in the study. After treatment the quality of sleep was improved in 35 cases (observation group) and was not improved in 74 patients (control group). The basic characteristics, coronary lesions of patients were compared between two groups. Compared with the control group, patients in observation group had significant higher proportion of males [80.0%(28/35) vs. 59.5%(44/74), χ 2=4.471, P=0.035], smoking history [85.7% (30/35) vs. 63.5% (47/74), χ 2=5.647, P=0.018], lower body mass index [(25.8±3.1) kg/m 2vs. (27.4±3.2) kg/m 2, t=2.461, P=0.033]. Compared with control group, the observation group had lower coronary Gensini score[(35.4±5.7) vs. (38.7±6.5), t=2.571, P=0.011], less number of stent[ (1.4±0.4) vs. (1.6±0.4), t=2.427, P=0.016]. And the lesions were mostly distributed in the right coronary artery in observation group (61.9%, 26/35) (χ 2=11.759, P=0.003). Conclusion:The improvement of sleep quality by PCI depends on the clinical features and coronary artery lesions of CHD patients with OSA.

ABSTRACT

Objective:To evaluate the effect of VX-765 on cognitive function in acute rapid eye movement (REM) sleep-deprived juvenile rats.Methods:Thirty-six clean-grade healthy male Sprague-Dawley rats, aged 3-4 weeks, weighing 52-101 g, were divided into 3 groups ( n=12 each) using a random number table method: control group (group C), acute REM group (group AREM) and VX-765 group (group V). Sleep deprivation model was established by modified multi-platform water environment method.In group V, VX-765 solution 10 mg/kg was intravenously injected via the tail vein at 9: 00 a. m.every day for 4 consecutive days.The equal volume of normal saline was given instead in C and AREM groups.Morris water maze and novel object recognition tests were performed for 4 consecutive days during sleep deprivation.The rats were then sacrificed after the end of Morris water maze and novel object recognition tests on 5th day, and hippocampi were removed for determination of the expression of interleukin-1beta (IL-1β) and IL-18 by Western blot. Results:Compared with group C, the latency of novel object recognition was significantly prolonged, the percentage of novel object exploration was shortened, and the number of head exploration was decreased, the percentage of novel object exploration and discrimination index were decreased, the number of crossing the original platform in Morris water maze test was reduced, the time of staying at the target quadrant was shortened, and the expression of IL-1β and IL-18 was up-regulated in AREM and V groups ( P<0.05). Compared with group AREME, the latency of novel object recognition was significantly shortened, the percentage of novel object exploration was prolonged, and the number of head exploration was increased, the percentage of novel object exploration and discrimination index were increased, the number of crossing the original platform in Morris water maze test was increased, the time of staying at the target quadrant was prolonged, and the expression of IL-1β and IL-18 was down-regulated ( P<0.05). Conclusion:VX-765 can improve the cognitive function in acute REM sleep-deprived juvenile rats, which is related to inhibiting hippocampal inflammatory responses.

ABSTRACT

Objective:To evaluate the effect of exogenous carbon monoxide (CO) on cell apoptosis during acute renal injury induced by hemorrhagic shock and resuscitation (HSR) in rats.Methods:Forty-eight clean-grade healthy male Sprague-Dawley rats, aged 9-10 weeks, weighing 350-400 g, were divided into 4 groups ( n=12 each) by a random number table method: sham operation group (S group), HSR group (H group), HSR plus CORM-3 group (HC group) and HSR plus iCORM-3 group (HiC group). Mean arterial pressure was maintained at 30-35 mmHg for 45 min by withdrawing blood from the femoral vein, and the shed blood was re-transfused within 15 min to reach the initial blood pressure for resuscitation.Normal saline was infused when necessary, and the model of HSR was established.CORM-3 4 mg/kg and iCORM-3 4 mg/kg were added during resuscitation in HC group and HiC group, respectively.Only femoral vein and artery puncture was performed in S group.Blood samples were obtained from the tail vein at 3 h after resuscitation for measurement of serum urea nitrogen (BUN) and creatinine (Scr) concentrations.Rats were sacrificed at 12 h after resuscitation, and renal tissues were obtained for determination of the expression of Bcl-2 and Bak protein and cleaved caspase-3 (by Western blot) and cell apoptosis (by TUNEL). The damage to the renal tubules was assessed by paller assay after HE staining.Bcl-2/Bak ratio and apoptosis rate were calculated. Results:Compared with group S, the serum BUN and Scr concentrations, paller scores, and apoptosis rate were significantly increased, Bcl-2/Bak ratio was decreased, and the expression of cleaved caspase-3 was up-regulated in H, HC and HiC groups ( P<0.05). Compared with group H, the serum BUN and Scr concentrations, paller scores, and apoptosis rate were significantly decreased, Bcl-2/Bak ratio was increased, and the expression of cleaved caspase-3 was down-regulated in group HC ( P<0.05). Compared with group HC, the serum BUN and Scr concentrations, paller scores, and apoptosis rate were significantly increased, Bcl-2/Bak ratio was decreased, and the expression of cleaved caspase-3 was up-regulated in group HiC ( P<0.05). There was no significant difference in the indexes mentioned above between group H and group HiC ( P>0.05). Conclusion:The mechanism by which exogenous CO improves acute kidney injury may be related to inhibiting cell apoptosis in a rat model of HSR.

ABSTRACT

Objective:To evaluate the effect of selective inhibitor of caspase-1 VX-765 on cognitive function in a rat model of hemorrhage shock and resuscitation (HSR).Methods:Forty-eight clean-grade healthy male Sprague-Dawley rats, aged 9-10 weeks, weighing 350-400 g, were divided into 4 groups ( n=12 each) using a random number table method: sham operation group (S group), HSR group (H group), VX-765 group (V group), and solvent control group (C group). The rats in H, V and C groups were subjected to hemorrhage by bleeding from femoral vein to achieve mean arterial pressure of 25-35 mmHg which was maintained at this level for 60 min followed by resuscitation with shed blood within 15 min to restore blood pressure, and normal saline was infused when needed.VX-765 1 mg/kg and 0.4% polyethylene glycol 1 mg/kg were intravenously injected via the femoral vein immediately after the end of resuscitation in V and C groups, respectively.Six rats in each group were selected and sacrificed at 12 h after the end of resuscitation, and the cerebral cortex was removed for determination of neuronal pyroptosis (by immunofluorescence) and degree of cortical edema (using T2-weighted imaging). Cognitive function was measured by open field test on day 7 after resuscitation in the rest 6 rats in each group. Results:Compared with S group, the pyroptosis rate in cortical neurons at 12 h after resuscitation and degree of cortical edema were significantly increased, the distance in the central square and the number of standing on the back legs were decreased on day 7 after resuscitation, and the time spent in the central square was shortened in H, V and C groups ( P<0.05). Compared with H and C groups, the pyroptosis rate in cortical neurons at 12 h after resuscitation and degree of cortical edema were significantly decreased, the distance in the central square and the number of standing on the back legs were increased on day 7 after resuscitation, and the time spent in the central square was prolonged in V group ( P<0.05). Conclusion:VX-765 can improve the cognitive function, and the mechanism may be associated with inhibiting pyroptosis in cortical neurons in a rat model of HSR.

ABSTRACT

Objective:To investigate the surgical complications in the treatment of stage Ⅰ endometrial cancer by robotic-assisted laparoscopy, the risk degree of Clavein-Dindo complications and the main risk factors affecting the occurrence of surgical complications.Methods:A retrospective case-control study was conducted in the First Affiliated Hospital of Zhengzhou University from October 2014 to June 2019. The patients were divided into robotic-assisted laparoscopy group and traditional laparoscopy group according to the operation mode, including 131 cases in robot group and 290 cases in traditional laparoscopy group. To compare the complications during and after operation and the risk degree of complications between the two groups by Clavein-Dindo classification standard, the age, body mass index (BMI), comorbidities, past history of pelvic surgery, American Society of Anesthesiologists (ASA) grade, preoperative anemia, number of pelvic lymph node resection, number of abdominal aortic lymph node resection, the total number of lymph node resection, operation time, surgical methods (robot surgery or traditional laparoscopic surgery) and other clinicopathological data were analyzed by logistic regression analysis.Results:(1) Complications of operation: the incidence of operative complications (including intraoperative and postoperative complications) in robot group was significantly lower than that in traditional laparoscopy group [(20.6%, 27/131) vs (34.8%, 101/290); χ 2=8.620, P=0.003)]. The incidence of intraoperative complications in robot group was lower than that in traditional laparoscopy group [1.5% (2/131) vs 6.2% (18/290); χ 2=4.368, P=0.037]. The incidence of intraoperative vascular injury in robot group was significantly lower than that in traditional laparoscopy group [0.8% (1/131) vs 5.2% (15/290); χ 2=4.798, P=0.022]. The incidence of postoperative complications in robot group was also lower than that in traditional laparoscopy group [19.1% (25/131) vs 28.6% (83/290); χ 2=4.303, P=0.038], but the incidence of postoperative lymphatic leakage in robot group was higher than that in traditional laparoscopy group [10.7% (14/131) vs 5.2% (15/290); χ 2=4.279, P=0.039]. (2) Clavein-Dindo classification: the incidence of Clavein-Dindo Ⅰ, Ⅲ, Ⅲ, Ⅳ and Ⅴ grade between two groups were respectively 3.8% (5/131) vs 11.0% (32/290), 13.7% (18/131) vs 14.5% (42/290), 3.1% (4/131) vs 8.6% (25/290), 0 (0/131) vs 0.3% (1/290), 0 (0/131) vs 0.3% (1/290), and the incidence of grade Ⅰ (χ 2=5.684, P=0.015) and Ⅲ (χ 2=4.361, P=0.037) complications were statistically significant. The incidence of severe complications in robot group (grade Ⅲ and above) was lower than that in traditional laparoscopy group [3.1% (4/131) vs 9.3% (27/290); χ 2=5.179, P=0.023]. (3) Analysis of influencing factors of surgical complications: univariate analysis showed that BMI (χ 2=15.801, P=0.000), preoperative anemia (χ 2=14.299, P=0.000), total number of lymph node resection (χ 2=10.425, P=0.001), surgical methods (χ 2=8.620, P=0.003) were related to the occurrence of surgical complications of endometrial carcinoma. Multivariate analysis showed that BMI ( OR=0.289, 95% CI: 0.097-0.864, P=0.026), preoperative anemia ( OR=0.309, 95% CI: 0.129-0.740, P=0.008), the total number of lymph node resection ( OR=0.624, 95% CI: 0.403-0.966, P=0.034) and surgical methods ( OR=3.491, 95% CI: 1.030-11.840, P=0.045) were independent risk factors for surgical complications of endometrial carcinoma. Conclusions:Compared with traditional laparoscopic surgery, robot-assisted laparoscopic surgery has fewer complications and lower incidence of severe complications. BMI, preoperative anemia, the total number of lymph node resection and surgical methods are independent risk factors for the occurrence of surgical complications of stage Ⅰ endometrial cancer.

ABSTRACT

Objective:To explore the application effect of cardiopulmonary exercise rehabilitation in patients with type 2 diabetes.Methods:100 patients with type 2 diabetes were randomly divided into control group and rehabilitation group. Patients in the control group received routine diabetes care and follow-up after discharge. On the basis of the treatment of control group, patients in the rehabilitation group were evaluated by cardiopulmonary exercise test and received exercise rehabilitation. The fasting blood glucose (FBG), postprandial blood glucose (PBG) glycosylated hemoglobin (HbA1C), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and body mass index (BMI) of all the patients were collected.Results:After 3 months of exercise, the BMI, TG, HDL-C, PBG, FBG and HbAlC values of the patients in the rehabilitation group were significantly improved compared with those in the control group, and the differences were statistically significant (all P<0.05). Conclusions:Compared with conventional education and follow-up, cardiopulmonary exercise rehabilitation exercise has a better effect on improving blood glucose, blood cholesterol, BMI, etc. in patients with type 2 diabetes.

ABSTRACT

OBJECTIVE@#To study the value of serum procalcitonin (PCT) combined with soluble triggering receptor expressed on myeloid cells-1 (STREM-1) in the differential diagnosis of bacterial diarrhea and viral diarrhea in children.@*METHODS@#A retrospective analysis was performed on the medical data of 73 children with bacterial infectious diarrhea (bacteria group) and 68 children with viral infectious diarrhea (virus group) who were treated from February 2018 to May 2019. The receiver operating characteristic (ROC) curve was used to analyze the diagnostic efficacy of serum PCT and STREM-1 for bacterial infectious diarrhea and viral infectious diarrhea.@*RESULTS@#Compared with the virus group, the bacteria group had significantly higher detection rates of fecal red blood cells (79% vs 43%, P<0.05) and pus (51% vs 19%, P<0.05), as well as significantly higher serum levels of PCT and STREM-1 (P<0.05). The ROC curve analysis showed that in the differential diagnosis of bacterial infectious diarrhea and viral infectious diarrhea, serum PCT had a cut-off value of 0.97 ng/mL and an area under the ROC curve (AUC) of 0.792, and STREM-1 had a cut-off value of 15.66 ng/mL and an AUC of 0.889. Serum PCT combined with STREM-1 had an AUC of 0.955, which was significantly higher than that of each index alone (P<0.05).@*CONCLUSIONS@#Children with bacterial diarrhea have increased serum levels of PCT and STREM-1 than those with viral diarrhea. Both serum PCT and STREM-1 can be used as the indices for the differential diagnosis of bacterial diarrhea and viral diarrhea in children, and the combined measurement of PCT and STREM-1 can improve the efficiency of differential diagnosis.

ABSTRACT

Objective@#To investigate the surgical complications in the treatment of stage Ⅰ endometrial cancer by robotic-assisted laparoscopy, the risk degree of Clavein-Dindo complications and the main risk factors affecting the occurrence of surgical complications.@*Methods@#A retrospective case-control study was conducted in the First Affiliated Hospital of Zhengzhou University from October 2014 to June 2019. The patients were divided into robotic-assisted laparoscopy group and traditional laparoscopy group according to the operation mode, including 131 cases in robot group and 290 cases in traditional laparoscopy group. To compare the complications during and after operation and the risk degree of complications between the two groups by Clavein-Dindo classification standard, the age, body mass index (BMI), comorbidities, past history of pelvic surgery, American Society of Anesthesiologists (ASA) grade, preoperative anemia, number of pelvic lymph node resection, number of abdominal aortic lymph node resection, the total number of lymph node resection, operation time, surgical methods (robot surgery or traditional laparoscopic surgery) and other clinicopathological data were analyzed by logistic regression analysis.@*Results@#(1) Complications of operation: the incidence of operative complications (including intraoperative and postoperative complications) in robot group was significantly lower than that in traditional laparoscopy group [(20.6%, 27/131) vs (34.8%, 101/290); χ2=8.620, P=0.003)]. The incidence of intraoperative complications in robot group was lower than that in traditional laparoscopy group [1.5% (2/131) vs 6.2% (18/290); χ2=4.368, P=0.037]. The incidence of intraoperative vascular injury in robot group was significantly lower than that in traditional laparoscopy group [0.8% (1/131) vs 5.2% (15/290); χ2=4.798, P=0.022]. The incidence of postoperative complications in robot group was also lower than that in traditional laparoscopy group [19.1% (25/131) vs 28.6% (83/290); χ2=4.303, P=0.038], but the incidence of postoperative lymphatic leakage in robot group was higher than that in traditional laparoscopy group [10.7% (14/131) vs 5.2% (15/290); χ2=4.279, P=0.039]. (2) Clavein-Dindo classification: the incidence of Clavein-Dindo Ⅰ, Ⅲ, Ⅲ, Ⅳ and Ⅴ grade between two groups were respectively 3.8% (5/131) vs 11.0% (32/290), 13.7% (18/131) vs 14.5% (42/290), 3.1% (4/131) vs 8.6% (25/290), 0 (0/131) vs 0.3% (1/290), 0 (0/131) vs 0.3% (1/290), and the incidence of grade Ⅰ (χ2=5.684, P=0.015) and Ⅲ (χ2=4.361, P=0.037) complications were statistically significant. The incidence of severe complications in robot group (grade Ⅲ and above) was lower than that in traditional laparoscopy group [3.1% (4/131) vs 9.3% (27/290); χ2=5.179, P=0.023]. (3) Analysis of influencing factors of surgical complications: univariate analysis showed that BMI (χ2=15.801, P=0.000), preoperative anemia (χ2=14.299, P=0.000), total number of lymph node resection (χ2=10.425, P=0.001), surgical methods (χ2=8.620, P=0.003) were related to the occurrence of surgical complications of endometrial carcinoma. Multivariate analysis showed that BMI (OR=0.289, 95%CI: 0.097-0.864, P=0.026), preoperative anemia (OR=0.309, 95%CI: 0.129-0.740, P=0.008), the total number of lymph node resection (OR=0.624, 95%CI: 0.403-0.966, P=0.034) and surgical methods (OR=3.491, 95%CI: 1.030-11.840, P=0.045) were independent risk factors for surgical complications of endometrial carcinoma.@*Conclusions@#Compared with traditional laparoscopic surgery, robot-assisted laparoscopic surgery has fewer complications and lower incidence of severe complications. BMI, preoperative anemia, the total number of lymph node resection and surgical methods are independent risk factors for the occurrence of surgical complications of stage Ⅰ endometrial cancer.

ABSTRACT

One hundred and nine consecutive coronary heart disease (CHD) patients with obstructive sleep apnea (OSA) undergoing percutaneous coronary intervention (PCI) during February 2016 to August 2018 were enrolled in the study. After treatment the quality of sleep was improved in 35 cases (observation group) and was not improved in 74 patients (control group). The basic characteristics, coronary lesions of patients were compared between two groups. Compared with the control group, patients in observation group had significant higher proportion of males [80.0%(28/35) vs. 59.5%(44/74), χ2=4.471, P=0.035], smoking history [85.7% (30/35) vs. 63.5% (47/74), χ2=5.647, P=0.018], lower body mass index [(25.8±3.1) kg/m2 vs. (27.4±3.2) kg/m2, t=2.461, P=0.033]. Compared with control group, the observation group had lower coronary Gensini score[(35.4±5.7) vs. (38.7±6.5), t=2.571, P=0.011], less number of stent[ (1.4±0.4) vs. (1.6±0.4), t=2.427, P=0.016]. And the lesions were mostly distributed in the right coronary artery in observation group (61.9%, 26/35) (χ2=11.759, P=0.003).Conclusion@#The improvement of sleep quality by PCI depends on the clinical features and coronary artery lesions of CHD patients with OSA.

ABSTRACT

Objective To investigate the resistances of larva and adult of Aedes albopictus to common insecticides in a county of Jining City, after the dengue fever outbreak in 2017, and to provide scientific support for rational use of insecticides. Methods The insecticide resistance was tested with exposure tubes for adult mosquitoes and dipping method for larvae.After collecting the larvae and breeding for one generation, the resistances of larvae were determined with the late third-instar or early fourth-instar larvae, and the resistance of adults was tested with the female mosquitoes at 3-5 days post eclosion. Results The insecticides mainly used in the county of Jining City in 2018 were pyrethroids such as permethrin, β-cyhalothrin, α-cypermethrin, and organic phosphorus pesticides such as phoxim.The median lethal concentration (LC50) values in the larva to temephos, deltamethrin, permethrin, beta-cypermethrin were 0.006 mg/L(RR=3.75), 0.021 mg/L(RR=52.50)、0.209 mg/L(RR=104.50)、0.016 mg/L (RR=17.78), with the lowest resistance to temephos and the highest to permethrin.Adult mosquitoes were sensitive to permethrin, with a knockdown rate of 97.62% and a mortality rate of 100%.When exposed to propoxur and malathion, the knockdown rates were 97.06% and 91.89%, the mortality rates were 97.06% and 93.24%.Aedes albopictus larvae were resistant to deltamethrin, α-cypermethrin, β-cyhalothrin, β-cypermethrin, with the knockdown rates of 88.00%, 95.31%, 91.04%, 97.10%, and the mortality rates were all less than 80.00%. Conclusion The larvae and adult mosquitoes of Aedes albopictus in the county of Jining City have developed different degrees of resistance to commonly used insecticides.The resistance should be under regular monitoring and the use of insecticides should be scientific and rational to delay the resistance production.
