OBJECTIVE: To screen the optimal regimen of acupuncture and moxibustion for obstructive sleep apnea hypopnea syndrome (OSAHS), so as to provide the evidences for clinical decision-making. METHODS: From 7 databases in Chinese and English i.e. the Full-Text Database of China Journal Network (CNKI), Wanfang Data Knowledge Service Platform (Wanfang), VIP Information Chinese Journal Service Platform (VIP), Chinese Biomedical Literature Database (SinoMed), PubMed, Web of Science (WOS) and Cochrane Library, randomized controlled trial (RCT) articals of OSAHS treated with acupuncture and moxibustion were searched. The quality of evidence was evaluated with the modified Jadad scale, the evaluation index was established and the optimal regimen of acupuncture and moxibustion for OSAHS was screened by multi-index decision analysis. RESULTS: A total of 10 RCTs were included, and the filiform needling therapy was optimal in treatment of OSAHS. The acupoints included Lianquan (CV23), Danzhong (CV17), Zhongwan (CV12), and bilateral Kongzui (LU6), Pishu (BL20), Fenglong (ST40), Zusanli (ST36), Yinlingquan (SP9) and Zhaohai (KI6). Zusanli (ST36) received the reinforcing method, Pishu (BL20) and Fenglong (ST40) were stimulated with the reducing technique, and the rest acupoints with the uniform reinforcing-reducing. Each acupoint was manually manipulated once every 10 min during the needle retention for 30 min. Acupuncture was delivered once a day, 5 times a week and for consecutive 4 weeks. Among the included literature, the severity of disease was not reported in detail, the filiform needling was the dominant intervention, the local acupoints such as Lianquan (CV23) and Panglianquan (Extra) were mainly selected. The apnea-hypopnea index and the minimum oxygen saturation were taken as the evaluation indexes, and the effect was evaluated in reference to the generally accepted standards. The attention to safety evaluation was insufficient, the report on methodology was not adequate and the quality was low. CONCLUSION Filiform needling is the dominant therapy of acupuncture and moxibustion for OSAHS, and the local acupoints are considered specially. But the quality of clinical research should be improved.

Objective:To evaluate the correlation between ultrasound parameters of internal carotid artery blood flow and regional cerebral oxygen saturation (rScO 2) in elderly patients undergoing coronary artery bypass grafting (CABG) under cardiopulmonary bypass (CPB). Methods:Sixty-four elderly patients undergoing elective CABG under CPB, aged 60-80 yr, regardless of gender, with body mass index of 18.1-28.9 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, with New York Heart Association class Ⅱ or Ⅲ, with left ventricular ejection fraction≥50%, were selected. The rScO 2 and ultrasonic parameters of internal carotid artery including peak systolic velocity (PSV-ICA), end-diastolic velocity (EDV-ICA), diameter (D-ICA) and blood flow volume (Q-ICA) were recorded before anesthesia induction (T 0), at surgical skin incision (T 1), at 30 and 60 min of CPB (mean value was calculated, T 2), and at 30 and 60 min after termination of CPB (mean value was calculated, T 3). The ratio of unilateral internal carotid artery blood flow to cardiac output (Q/CO) was calculated. The receiver operating characteristic curve was used to analyze the accuracy of ultrasound parameters of internal carotid artery blood flow in predicting rScO 2 < 60%. Results:PSV-ICA was positively correlated with rScO 2 at T 0, T 1 and T 3 ( P<0.05), but no correlation was found between PSV-ICA and rScO 2 at T 2 ( P>0.05). There was no correlation between EDV-ICA and rScO 2 at each time point ( P>0.05). Q-ICA was positively correlated with rScO 2 at each time point ( P<0.05). Q/CO was not correlated with rScO 2 at T 1 ( P>0.05), but Q/CO was positively correlated with rScO 2 at T 2 and T 3 ( P<0.05). During the non-CPB period (T 0, T 1, T 3), the cutoff values of PSV-ICA and Q-ICA in predicting rScO 2< 60% were 51.35 cm/s and 283.5 ml/min respectively, the sensitivity was 0.900 and 0.900 respectively, and the specificity was 0.610 and 0.857 respectively (AUC=0.761, P=0.006; AUC=0.903, P< 0.001). During the CPB period, the cutoff values of Q-ICA and Q/CO in predicting rScO 2<60% were 296.5 ml/min and 5.84% respectively, the sensitivity was 0.900 and 0.800, and the specificity was 0.545 and 0.659 (AUC=0.764, P=0.001; AUC=0.748, P=0.002), respectively. Conclusions:PSV-ICA and Q-ICA are positively correlated with rScO 2 during the non-CPB period, and Q-ICA and Q/CO are positively correlated with rScO 2 during the CPB period in elderly patients undergoing CABG. PSV-ICA, Q-ICA and Q/CO can accurately predict rScO 2<60%.

Objective:To study the survival and prognostic factors for the recurrent extracranial malignant germ cell tumors (MGCTs) in children, and to explore feasible salvage treatment.Methods:A retrospective study.Pediatric patients with recurrent extracranial MGCTs diagnosed in Shanghai Children′s Medical Center between January 2010 and January 2020 were retrospectively recruited.Comprehensive treatment regimens included surgery, chemotherapy and radiation.Kaplan-Meier survival analysis and Cox regression model were employed to analyze the survival and prognostic factors for children with recurrent extracranial MGCTs.Results:A total of 172 children with extracranial MGCTs were treated, including 21 (12.2%) recurrent cases.The median time of MGCT recurrence after the end of the first treatment was 11 months.Finally, 19 patients were recruited after excluding 2 non-eligible cases, including 10 boys and 9 girls with the age at recurrence of 26 (8-170) months.The follow-up time was 57 (13-122) months.Salvage chemotherapy, complete resection and radiotherapy were performed in 16, 14 and 4 patients, respectively.The 4-year overall survival (4yr-OS) rate was (82.5±9.2)%(19 cases). The 4yr-OS rate was significantly higher in patients managed with surgery but without adjuvant chemotherapy at the initial treatment (13 cases) than those managed with chemotherapy at the initial treatment (6 cases)[(92.3±7.4)% vs.(60.0%±21.9)%, P=0.002]. Univariant and Cox multivariant regression analyses showed that failure to achieve the normal range of alpha fetoprotein after 3 cycles of chemotherapy significantly influenced the survival of recurrent extracranial MGCTs. Conclusions:For patients with recurrent extracranial MGCTs, comprehensive treatment approaches like complete surgical resection, chemotherapy, and radiotherapy offer a favorable survival rate.Specifically, recurrent and re-treated patients who initially received surgery alone without adjuvant chemotherapy have a higher survival rate compared to those who received chemotherapy during the initial treatment.

Objective To explore the differences of regional homogeneity(ReHo)between overweight and normal weight male patients with type 2 diabetes mellitus(T2DM)during rest and their correlations with clinical features.Methods Twenty-five untreated male overweight T2DM(OW-T2DM)patients,25 untreated male normal weight T2DM(NW-T2DM)patients and 25 healthy controls(HC)were enrolled.The brain structure and resting-state functional magnetic resonance imaging(rs-fMRI)data were collected from all subjects.The brain structure and rs-fMRI data were preprocessed,and ReHo values of all brain regions were calculated for all subjects.ReHo values were compared among three groups and between groups respectively via the methods of one-way analysis of variance and two-sample t-test.To address the problem of multiple comparisons,the method of AlphaSim was performed(the threshold was set at P<0.005,the number of voxel clusters was>12).In addition,Pearson correlation analysis was performed to explore the relationships between ReHo values of the abnormal brain regions and clinical features in patients.Results(1)The brain regions showed differences of ReHo values among three groups were mainly distributed in the right hemisphere,including the superior parietal gyrus,superior marginal gyrus and superior occipital gyrus;(2)Compared with HC,NW-T2DM patients showed significantly decreased ReHo values in the right medial superior frontal gyrus,right middle cingulate gyrus and left anterior cingulate gyrus;(3)Compared with HC,OW-T2DM patients showed significantly decreased ReHo values in the bilateral postcentral gyrus and bilateral middle cingulate gyrus;(4)Compared with NW-T2DM patients,OW-T2DM patients showed significantly decreased ReHo values in the right superior parietal gyrus,right superior occipital gyrus and left cuneus;(5)ReHo values of the right medial superior frontal gyrus and right superior parietal gyrus were negatively correlated with hemoglobinA1c(HbA1c)level and body mass index(BMI),respectively,in all patients.Conclusion The occurrence of T2DM in male patients may lead to the declined activity of brain regions located in the default mode network(DMN),while overweight may further lead to decreased brain activity within the attention and visual recognition network in male T2DM patients.

[Objective] To understand the resistance mechanisms, virulence characteristics, and pathogenicity of hypervirulent Klebsiella pneumoniae (hvKp), which causes pyogenic liver abscess (PLA), and to provide related data for clinical treatment of infection caused by this type of bacteria. [Methods] We collected three strains of Klebsiella pneumoniae isolated from the liver abscess fluid of patients with liver abscesses in various departments of The First Affiliated Hospital of Xi’an Jiaotong University. The hypervirulent phenotypes were determined by the wire test, and drug sensitivity was assessed using the VITEK 2 compact automatic microbiological analyzer. Molecular characteristics such as podocarp serotypes, multi-locus sequence typing (MLST), virulence genes, and drug resistance genes were identified through whole-genome sequencing. Additionally, a mouse infection model was established to evaluate pathogenicity. [Results] The isolates were sticky, with mucous thread pulling length >5 mm, all of which exhibited high viscosity phenotypes. Except 146007, which is a multidrug-resistant bacterium, the other two strains had higher antibiotic sensitivity. Whole genome sequencing revealed that the isolates were of high-virulence type, carrying the toxin plasmid rmpADC/rmpA2, iron uptake system, bacterial hairs, secretion system, and other virulence factors. All the three isolates tested positive for rmpA/rmpA2 combined with iucA/iutA, indicating they could be classified as hvKp. Multiple resistance genes were detected, such as β-lactamase like blaTEM, blaSHV, and blaCTX-M. The isolates were highly pathogenic to mice, as evidenced by the diseased organs of the deceased mice observed on autopsy. [Conclusion] The three strains of hvKp isolated in this study carried multiple drug-resistant genes and were highly pathogenic, which suggests that in laboratories and clinical practices it is imperative to promptly identify and adopt necessary disposal strategies to prevent further spread of hvKp.

Objective To compare the differences in the levels of lactate dehydrogenase(LDH),creatine kinase(CK),and neuron-specific enolase(NSE)in the cerebrospinal fluid(CSF)between the patients with purulent meningitis(PM)and those with tuberculous meningitis(TBM)and evaluate the utility of the three biomarkers in the differentiation of PM and TBM.Methods Thirty-five PM patients and 45 TBM patients who attended the Department of Neurology from December 2019 to December 2021 were enrolled in this study.The CSF samples were collected from the patients before treatment.The levels of LDH,CK,NSE,and glucose,protein,and chloride in CSF were measured and compared between PM and TBM patients.The correlation between the biomarkers in CSF was analyzed by Pearson correlation coefficient.Linear regression analysis was performed to analyze the risk factors for the occurrence of TBM.Receiver operating characteristic(ROC)curves were plotted to evaluate the discriminative value of CSF LDH,CK,NSE alone or in combination in differential diagnosis of PM and TBM.Results Patient age,gender,clinical features such as fever,pathological signs,vomiting,limb twitching,and CSF levels of glucose and protein did not show significant difference between TBM patients and PM patients(P＞0.05).TBM was associated with significantly higher LDH and NSE levels in CSF and significantly lower CK level and chloride in CSF compared to PM(P＜0.05).Pearson correlation analysis showed that LDH level in CSF was negatively correlated with CK and chloride(r＜0,P＜0.05),and positively correlated with NSE(r＞0,P＜0.05).CK was negatively correlated with NSE(r＜0,P＜0.05),and positively correlated with chloride(r＞0,P＜0.05).NSE was negatively correlated with chloride(r＜0,P＜0.05).Linear regression analysis showed that LDH,CK,NSE,and chloride levels in CSF were all associated with the occurrence of TBM(P＜0.05).ROC curves demonstrated that the AUCs of CSF levels of LDH,CK,NSE alone and in combination for differentiation between PM and TBM were 0.849(95％CI:0.768-0.930),0.858(95％CI:0.779-0.937),0.851(95％CI:0.771-0.931),and 0.954(95％CI:0.911-0.996),respectively.Conclusions The clinical features are similar for PM and TBM patients.However,the levels of LDH,CK,and NSE in CSF are different between PM and TBM.LDH,CK,NSE in combination may improve the differential diagnosis between PM and TBM.

Objective To explore the changes and significane of USP20 and HIF-α expression in breast cancer.Methods Following transfection of shRNA-USP20 lentivirus into breast cancer MDA-MB-231 cells,the gene and protein expression levels of USP20 were detected using fluorescence quantitative PCR and Western Blot.Subsequently,the overexpression of USP20 was observed to determine its effect on HIF-α expression.Similarly,siRNA-USP20 was used to knock down USP20 in breast cancer MDA-MB-231 cells,followed by detection of gene and protein expression levels using fluorescence quantitative PCR and Western Blot.The subsequent changes in HIF-α expression were then examined.Rusults The positive expression rates of USP20 and HIF-α in breast cancer tissues were 69.6%and 46.83%,respectively,while they were negatively expressed in the adjacent normal tissues,with statistically significant differences(P＜0.01).The positive expressions of USP20 and HIF-α were predomi-nantly observed in the cytoplasm of breast cancer tissue,with a smaller amount present in the nucleus.There was a significant positive correlation between USP20 and HIF-α in breast cancer.Following transfection of shRNA-USP20 lentivirus into MDA-MB-231 cells,both the protein and gene expression levels of USP20 significantly increased(P＜0.01).Over-expression of USP20 did not affect HIF-α mRNA levels but led to a significant increase in HIF-α protein expression(P＜0.01).Conversely,siRNA-USP20 interference resulted in a significant decrease in both the protein and gene expression levels of USP20(P＜0.01),without affecting HIF-α mRNA levels;however,it caused a notable reduction in HIF-α protein expression(P＜0.01).Conclusion The expression of USP20 exhib-ited a significant positive correlation with HIF-α in breast cancer.Overexpression of USP20 led to a substantial increase in HIF-α protein expression,while knock-down of the USP20 gene resulted in a significant decrease in HIF-α protein levels.Therefore,it can be inferred that USP20 may exert its influence on the development of breast cancer through modulation of HIF-α expression,thereby providing crucial experimental evidence for clinical treat-ment,prognosis,and further investigations.

Nociceptive sensory neurons are widely distributed throughout various parts of the body to detect harmful stimu-li and transmit pain sensations.In recent years,the interactions between nociceptive sensory neurons and the immune system have garnered increasing attention from researchers.Immune cells and inflammatory factors promote the activation of nocicep-tors and the transmission of pain;conversely,nociceptors also participate in regulating the body's immune functions.The bal-ance between these two systems is beneficial for self-protection under harmful stimuli and infection.Moreover,this neuroim-mune interaction may underlie the coexistence and mutual promotion of hyperalgesia and inflammation.This review primarily discusses the role of interactions between nociceptors in various body regions and the immune system in pain,as well as the po-tential molecular mechanisms involved.This study aims to provide insights and theoretical foundations for developing new strat-egies for pain management.
