ObjectiveTo investigate the menstrual conditions of women infected with COVID-19 in Shanghai and analyze the influencing factors. MethodsFrom December 2022 to March 2023， menstrual data from 281 women infected with COVID-19 in Shanghai were collected with a questionnaire survey， including usual menstrual characteristics， the most recent menstrual period post-infection， symptoms of infection， and medication usage. According to the crossover period between the menstrual period and the infection period of the respondents， the samples were divided into two groups for comparative analysis： those whose menstrual and infection periods overlapped （positive group） and those whose menstruation started after conversion to virus-negative （negative conversion group）. ResultsAmong the 281 respondents， 196 （65.8%） experienced menstrual changes. Among them， 145 （51.6%） had changes in menstrual volume， color and texture， and 109 （38.8%） had changes in menstrual duration or cycle. Decreased menstrual volume （22.1%）， darker color （23.49%）， thicker texture （21.0%）， increased blood clots （16.7%）， and prolonged duration （21.8%） were observed in both groups. The rate of changes in menstrual volume， color， and texture was higher in the positive group （56.8%， 69/110） than that in negative group （37.3%， 76/171） （P<0.05）. Regarding the menstrual cycle changes， the rate of early onset was higher in the positive group （14.5%） compared to the negative conversion group （3.5%）（P<0.05）， while the rate of delayed menstruation was higher in the negative conversion group （25.1%） than that in the positive group （5.5%） （P<0.05）. Correlation analysis showed a weak association between sore throat and menstrual changes （r=0.154， P<0.05）. ConclusionSome women infected with COVID-19 experience short-term changes in their menstrual conditions， characterized by reduced volume， darker color， thick texture， increased clots， and prolonged menstrual duration， reflecting a pathogenesis of blood stasis. Menstruation during the infection period tends to occur earlier， while delayed menstruation is more prevalent at post-conversion.

Objective:To understand the epidemiological characteristics and spatiotemporal distribution of viral encephalitis in children and adolescents in Henan Province from 2012 to 2023.Methods:The information about viral encephalitis cases from October 1, 2012 to July 26, 2023 were collected from Zhengzhou Children's Hospital (National Children's Regional Medical Center),Henan Provincial Children's Hospital for the analyses on temporal distribution the cases, the severe illness rate, age distribution, pathogen type and imaging findings of the cases.Results:A total of 6 276 cases of viral encephalitis were included in this study after excluding cases with incomplete information. The cases mainly originated from Zhengzhou (38.96%), followed by Zhoukou (9.93%), Xuchang (8.68%), Zhumadian (7.90%) and Pingdingshan (7.39%). The cases in boys accounted for 62.13% and the cases in girls accounted for 37.87%. Most cases (72.45%) occurred in age group 7-13 years. The overall rate of severe illness cases was 4.51% from 2012 to 2023. There were significant differences in severe illness cases among different areas and years ( χ2=5.33, P=0.021; χ2=48.14, P<0.001). Enteroviruses were mainly detected (31.57%), in which Coxsackie virus was predominant (58.37%). Imaging findings showed that cerebral hemisphere damage was most common in children and adolescents with viral encephalitis (54.93%). Conclusions:From 2012 to 2023, more cases of viral encephalitis occurred in boys in Henan. Children and adolescents aged 7-13 years were the main affected group. The prevention of enteroviruses infection, especially Coxsackie virus, needs to be strengthened. Special attention should be paid to the prevention of cerebral hemisphere damage after viral encephalitis diagnosis.

AIM:To examine how the variation of the β1-adrenergic receptor gene affects the occurrence of ventricular arrhythmias and the prognosis over a 6-month period in individuals suffering from acute ST-segment elevation myocardial infarction(STEMI).METHODS:A study was conducted retrospectively,where patients diagnosed STEMI and treated at Yunfu City People's Hospital between January 2021 and February 2023 were included based on predefined criteria.The patients were then divided into three groups according to their genotypes of the β1-adrenergic receptor Arg389Gly gene polymorphism:CC group(Arg389Arg),CG group(Arg389Gly),and GG group(Gly389Gly).Discrep-ancies in initial clinical data upon admission[such as Killip classification,heart rate,systolic and diastolic blood pres-sure,left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVDD),and serum tumor necro-sis factor alpha(TNF-α),N-terminal pro-B-type natriuretic peptide(NT-proBNP),creatine kinase MB(CK-MB)and high-sensitivity C-reactive protein(hs-CRP)],and outcomes gathered during a 6-month follow-up via telephone after dis-charge(heart rate,NT-proBNP,CK-MB,LVEF,LVDD,and occurrences of major adverse cardiac events)were com-pared across the three groups.RESULTS:The study enrolled a total of 178 STEMI patients with ventricular arrhythmias,comprising 87 cases in CC group(48.9％),73 cases in CG group(41.0％),and 18 cases in GG group(10.1％).There were no notable variances in demographic characteristics such as age,sex,weight,BMI,smoking history,alcohol con-sumption history,comorbidities,blood pressure,heart rate,Killip classification(III amd IV),TNF-α,NT-proBNP,CK-MB,hs-CRP,LVEF and LVDD across the three groups(P>0.05).Following a 6-month monitoring period,the cardiac function parameters in CG and GG groups exhibited significant improvement compared to those in CC group(P<0.05),with noteworthy lower levels of NT-proBNP and CK-MB in GG group in contrast to CG group(P<0.05).Notably,there were significant discrepancies in the incidence of major adverse cardiac events during the follow-up period among the study groups,with 17 cases in CC group(19.5％),5 cases in CG group(6.9％),and 1 case in GG group(5.6％)(χ2=6.887,P<0.05).CONCLUSION:There is no correlation between the severity of STEMI accompanied by ventricular arrhyth-mias and the β1-adrenergic receptor Arg389Gly gene polymorphism.However,this gene variant is connected with en-hancements in cardiac function and short-term prognosis post-treatment.

Objective:To explore the effect of ointment massage on the postoperative recovery of newborns who had intestinal tract operation, aim to construct an effective post-operative ointment and massage scheme and to enrich the content of enhanced recovery after surgery in the field of newborns.Methods:Delphi expert inquiry method was used to construct the ointment message scheme. A total of 64 newborns undergone intestinal surgery from May 2022 to May 2023 in Guangdong Women and Children Hospital were selected as study subjects and divided into routine group (34 cases) and ointment group (30 cases) by random number table method. In addition to routine treatment and nursing, the newborns in the ointment group also received ointment massage. The postoperative gastrointestinal drainage volume, fasting days, the first feeding time, hospital stay and the number of cases of vomiting and abdominal distension between the two groups were compared.Results:A total of 16 experts with (38.93 ± 5.13) years old were inquired, 6 males and 10 females. The effective questionnaire response rates for the two rounds of expert inquiry were 16/16 and 15/16, the expert authority coefficients were both≥0.80, the Kendall′s W coefficients were 0.117 and 0.107, with statistically significant differences (both P<0.05). A ointment message scheme consisting of 8 acupoints and 7 kinds of traditional Chinese medicines was determined. In the routine group, there were 19 males and 15 females with (268.47 ± 11.27) gestational age. In the ointment group, there were 20 males and 10 femles with (271.93 ± 10.36) gestational age. The postoperative gastrointestinal drainage volume, fasting days, the first feeding time and the hospital stay in the ointment group were 74.0 ml, 6.0 d, 158.5 h and 13.0 d, which had significant differences with the 184.5 ml, 7.5 d, 192.0 h, 16.5 d in the routine group ( Z values were 2.07-2.45, all P<0.05). The incidence of vomiting and abdominal distension in the ointment group were both 8 cases, which were lower than the 19 and 18 cases in the routine group with a statistically significant difference ( χ2 = 5.58, 4.56, both P<0.05). Conclusions:The ointment massage in this study has a positive impact on the recovery of newborn infants after intestinal surgery, with high safety, in line with enhanced recovery after surgery concept, and is worthy of promotion.

Objective:To explore the latent profiles of intellectual humility in primary colorectal cancer (CRC) postoperative patients and analyze the correlation between their intellectual humility and self-management.Methods:A total of 250 patients with primary CRC who underwent radical tumor surgery in anorectal department of Qinghai Provincial Hospital of Traditional Chinese Medicine from October 2021 to June 2023 were selected to accept a cross-sectional survey through convenient sampling method. They were surveyed by basic information questionnaire, comprehensive intellectual humility scale and cancer patient self-management assessment scale.Results:Finally, 243 valid questionnaires were obtained, it contained 125 males and 118 females with age 32- 68 (52.45 ± 10.24) years old. The score of primary CRC postoperative patients′intellectual humility was (67.59 ± 13.26) points, it could be divided into low-level intellectual humility type with 30 cases(12.34%), confident intellectual humility type with 36 cases (14.82%), mid-level intellectual humility type with 93 cases (38.27%), and high-level intellectual humility type with 84 cases (34.57%). Disordered multi-classes Logistic regression analysis showed that gender(female, OR=2.465), education level (high school or vocational school, OR=0.012) and diagnosis time(1-3 months, OR=15.289) were significant influencing factors to primary CRC postoperative patients from confident intellectual humility type (all P<0.05), gender (female, OR=5.354) and education level (high school or vocational school education, OR=0.012) were significant influencing factors to primary CRC postoperativepatients from mid-level intellectual humility type (both P<0.05), gender (female, OR=11.253), age (<45 years old, OR=7.532), education level (high school or vocational school, OR=0.017) and diagnosis time (<1 month, OR=0.054) were significant influencing factors to primary CRC postoperative patients from high-level intellectual humility type (all P<0.05). The score of primary CRC postoperative patients′self-management was (142.03 ± 19.83) points. There were statistically significant differences among scores of self-management, daily life management, symptom management and other six dimensions in patients from different categories of intellectual humility ( F values were 25.42-490.55, all P<0.05). There were positive correlation between the CRC patients′inteilectual humility and postoperatice self-managemeat ( r values were 0.373 - 0.749, all P<0.05). Conclusions:Primary CRC patients have a moderate level of knowledge humility and postoperative self-management. Their knowledge humility can be divided into low knowledge humility type, confident knowledge humility type, medium knowledge humility type, and high knowledge humility type. Knowledge humility can enhance postoperative self-management, and targeted interventions should be carried out for CRC patients with different types of knowledge humility to provide them with better cancer care and enhance their self-management level.

Purpose To investigate the characteristics of 18F-Florbetaben(18F-FBB)β-amyloid(Aβ)PET imaging in different brain regions of Alzheimer's disease(AD)patients with different degrees of cognitive impairment,and to explore the correlation between Aβ deposition and cognitive dysfunction.Materials and Methods A total of eighteen patients with a clinical diagnosis of probable AD from August 2022 to October 2023 were retrospectively included in Huashan Hospital.All patients had Aβ abnormal deposition in the brain as confirmed by 18F-FBB PET imaging.According to the severity of symptoms,they were divided into the AD-induced mild cognitive impairment(MCI)group(8 cases)and the dementia group(10 cases).In addition,12 healthy controls were included.First,the standardized uptake value ratio of abnormal Aβ deposition in the frontal lobe,lateral parietal lobe,lateral temporal lobe,anterior and posterior cingulate gyrus,and compound cortex was semi-quantitatively calculated and compared among the three groups based on the subjects'brain MRI and automated anatomical labeling template.The correlation between the degree of Aβ deposition in the brains of AD patients and cognitive scale scores(mini-mental state examination,Montreal cognitive assessment)was then further analyzed.Results The standardized uptake value ratio values of Aβabnormal deposition in the frontal lobe,lateral temporal lobe,lateral parietal lobe,anterior and posterior cingulate cortex and compound cortex in the AD-induced MCI and dementia groups were significantly higher than those in the healthy controls(t=7.442-9.151,all P＜0.05).However,there was no significant difference in the standardized uptake value ratio values of Aβ abnormal deposition in the above brain regions between the MCI and dementia groups(t=0.312-0.996,all P＞0.05).In addition,there was no significant correlation between the degree of Aβ deposition in the brain and the cognitive scale scores(mini-mental state examination,Montreal cognitive assessment)in the AD-induced MCI and dementia groups(r=-0.049-0.050,all P＞0.05).Conclusion Aβ deposition in the brains of AD-induced MCI and dementia is significantly higher than in the healthy controls.However,Aβ deposition cannot identify AD patients with different degrees of cognitive impairment,reflecting that Aβ deposition has certain limitations in assessing the severity of clinical symptoms of AD.

Objective To observe the effects of different frequencies of electroacupuncture on the degree of atrophy of quadriceps femoris in rabbits with anterior cruciate ligament(ACL)injury model;To explore the possible mechanisms of electroacupuncture in treating ACL injury.Methods Totally 24 New Zealand rabbits were randomly divided into blank group,model group,low-frequency electroacupuncture group and high-frequency electroacupuncture group,with 6 rabbits in each group.Except for the blank group,ACL injury models were established in the other groups.On the 7th day after modeling,the low-frequency electroacupuncture group and the high-frequency electroacupuncture group performed electroacupuncture treatment(continuous wave,frequency of 2 Hz and 100 Hz respectively,and left the needle in place for 20 min)at"Xuehai"and"Liangqiu"of the operation side,and the remaining groups were only grasped and immobilized,for 21 days.The mass ratio of the quadriceps femoris was calculated,the histopathological morphology of the quadriceps femoris tissue of the rabbits in each group was observed by HE staining,the expressions of NO,iNOS in quadriceps femoris tissue were detected by ELISA,the content of ROS in quadriceps femoris tissue was detected by fluorescent probe,the protein expressions of PERK,ATF6,IRE1,MuRF1,MAFbx in quadriceps femoris tissue were detected by Western blot.Results Compared with the blank group,the quadriceps femoris muscle mass ratio of the model group rabbits was significantly reduced(P<0.01),with irregular arrangement of muscle cells,accompanied by swelling and atrophy,significant interstitial edema,and extensive inflammatory infiltration,the contents of NO,iNOS and ROS in quadriceps femoris tissue significantly increased(P<0.01),while the expressions of PERK,ATF6,IRE1,MuRF1 and MAFbx proteins significantly increased(P<0.01).Compared with the model group,the quadriceps femoris muscle mass ratio in the low-frequency and high-frequency electroacupuncture groups significantly increased(P<0.01),with regular arrangement of muscle cells,improved swelling and atrophy of cells,and reduced interstitial edema and inflammation,the contents of NO,iNOS and ROS in quadriceps femoris tissue were significantly reduced(P<0.01),and the expressions of PERK,ATF6,IRE1,MuRF1 and MAFbx proteins significantly decreased(P<0.01).Moreover,the low-frequency electroacupuncture group had better effects than the high-frequency electroacupuncture group(P<0.05).Conclusion Different frequencies of electroacupuncture intervention in ACL injury rabbits can better delay the degree of quadriceps femoris atrophy,and its mechanism may be related to reducing the expressions of oxidative metabolites NO,iNOS,ROS,and reducing the expressions of endoplasmic reticulum stress-related proteins PERK,ATF6,IRE1 in quadriceps fermoris,which in turn inhibit the expressions of quadriceps atrophy factors MuRF1,MAFbx,and delaying the degradation of quadriceps muscle proteins.The effect of low-frequency electroacupuncture is superior to the high-frequency electroacupuncture.

Objective To analyze and summarize the acupoint selection law of acupuncture and moxibustion for the treatment of temporomandibular joint dysfunction syndrome(TMD)using data mining technology.Methods Clinical literature about acupuncture and moxibustion for the treatment of TMD was retrieved from CNKI,Wanfang Data,VIP,CBM,PubMed,Web of Science,Embase and Cochrane Library from the establishment of the databases to March 1,2024.Excel 2021 was used to establish a prescription database of acupoints.SPSS Modeler 18.0 and SPSS Statistics 27.0 were used to analyze the frequency of use of acupoints,meridians,locations,specific acupoints,and the analysis of association rules,factor analysis,and clustering analysis.Results A total of 480 articles and 480 prescriptions were included in the study,containing 90 acupoints,with a total frequency of 2 290 times.The high-frequency acupoints were Xiaguan,Hegu,Jiache,Tinggong and Ashi point;the commonly used meridians were the stomach meridian,large intestine meridian,small intestine meridian,bile meridian,and triple-energizer meridian;the most frequently chosen acupoints were the Jiaohui acupoints,Yuan acupoints and Wushu acupoints;and mostly involved acupoints were located at the head and neck area,the upper limb area and the lower limb area.The association analysis showed that the top five combinations were"Xiaguan-Hegu","Xiaguan-Jiache","Xiaguan-Hegu-Jiache","Xiaguan-Tinggong","Xiaguan-Tinggong-Jiache";clustering analysis showed that five valid clusters were extracted;factor analysis extracted seven valid common factors.Conclusion The core acupoints of acupuncture and moxibustion for the treatment of TMD is Xiaguan-Hegu-Jiache-Tinggong,and mainly follows the principle of combining proximal and distal acupoints.

Objective To explore application value of transaxillary single-port gasless endoscopic-assisted fibroadenomas excision in adolescents.Methods A retrospective analysis was conducted on clinical data of 60 cases of fibroadenoma from June 2019 to June 2023.The patients were 17.3(range,13-19)years old.There were 54 cases of unilateral tumors and 6 cases of bilateral tumors.The average number of tumors was 2.5(range,1-13),and the mean tumor diameter was 4.0(range,3-10)cm.The fibroadenoma excision was performed by using transaxillary single-port gasless endoscopy.Results Of the 60 patients,the average operation time was 64.9(range,35-130)min and the intraoperative blood loss was less than 20 ml.Postoperative complications occurred in 5 cases(8.3％).At 3 months after surgery,the psychosocial well-being scores of BREAST-Q Scale were increased from(79.2±8.9)to(83.4±9.9)(P＜0.001).Conclusion Transaxillary single-port gasless endoscopic-assisted fibroadenomas excision is safe and effective for multiple or large fibroadenomas in adolescents,offering minimal invasion and concealed incision.

Objective:To investigate the association of total sleep time (TST) and oxygen desaturation index (ODI) with hypertension in patients with obstructive sleep apnea/hypopnea syndrome (OSA).Methods:A total of 440 OSA patients admitted to Yixing Hospital from January 2017 to December 2022 were consecutively enrolled, including 236 patients with hypertension (OSA+hypertension group) and 204 patients without hypertension (OSA group). The clinical data and polysomnograpic parameters were collected. Univariate and multivariate logistic regression was used to analyze the related factors of OSA complicated with hypertension. The multiplicative interaction between TST and ODI on OSA with hypertension was analyzed. A two-factor cross-over analysis of TST and ODI was performed and the additive interaction model was used to analyze the additive interaction between TST and ODI on OSA with hypertension.Results:Univariate logistic regression showed that male sex, smoking, diabetes, coronary heart disease, TST <7 h, age, body mass index, neck circumference, waist circumference, Epworth Sleepiness Scale (ESS) score, TST, AHI, ODI>16 times/h, triglyceride, high density lipoprotein cholesterol and fasting blood glucose were positively correlated with hypertension in OSA patients (all P<0.05). Multivariate logistic regression analysis showed that smoking ( OR=4.327, 95% CI: 2.499-2.499, P<0.001), TST<7 h ( OR=1.748, 95% CI: 1.079-2.832, P=0.023) and ODI>16 times/h ( OR=3.482, 95% CI: 2.016-6.014, P<0.001) were independently associated with hypertension in OSA patients. After introducing a multiplicative term and adjusting for confounding factors, there was a positive multiplication interaction between TST <7 h and ODI>16 times/h ( OR=2.958, 95% CI: 1.079-8.113, P<0.050). Multivariate logistic regression analysis showed that the risk of hypertension in OSA patients with TST<7 h and ODI>16 times/h was 7.196 times (95% CI: 3.421-15.137) higher than that in patients with TST≥7 h and ODI≤16 times/h. The additive interaction model showed a synergistic effect between TST<7 h and ODI>16 times/h, with S value of 4.302 (95% CI: 1.566-11.815), RERI value of 4.756 (95% CI: 0.642-8.869) and API value of 66.10% (95% CI: 43.10%-89.10%). Conclusion:Shortened sleep duration and increased ODI are independent risk factors for hypertension in OSA patients, and when they coexist, the risk of hypertension in OSA patients is further increased.
