It is believed that patients with cirrhotic ascites exhibit a pathological mechanism characterized by the decline of healthy qi and the accumulation of pathogenic factors. Clinically， treatment should be based on the theory of tonification and purging， with a staged approach distinguishing between the active phase and the remission phase. The balance between tonification and purging should be adjusted according to the progression of pathogenic and healthy actors. In the acute phase， purging should take precedence over tonification， using purging as a means of tonification to facilitate the flow of water and qi through the triple energizer. The severity of water retention， dampness， blood stasis， and heat should be carefully assessed to ensure thorough elimination of pathogenic factors while avoiding harm to healthy qi. Medication adjustments should be made once the pathogenic factors are significantly weakened. In the remission phase， an integrated approach combining both tonification and purging should be adopted， incorporating purging within tonification to clear residual pathogens and prevent recurrence. Concurrently， proactive treatment of the underlying disease is essential to achieve complete recovery and prevent the recurrence of ascites.

Objective To analyze the diagnostic quality of imported malaria in Hubei Province from 2019 to 2022, and to further improve the diagnostic level and consolidate the achievements in eliminating malaria. Methods The samples of reported malaria cases in Hubei were collected by the provincial reference laboratory (PRL) from 2019 to 2022. The microscopy and fluorescent PCR were performed to confirm the infection of plasmodium species of each case．The positive coincidence rate and species coincidence rate were analyzed and compared． Results A total of 257 imported malaria cases were reported in Hubei Province from 2019 to 2022. Among 229 malaria cases were confirmed, the overall coincidence for malaria diagnosis was 91.24% (229/251), and the overall coincidence rate for parasite species identification was 86.03% (197/229). The difference in species coincidence rate among different years was statistically significant (χ²=10.458, P<0.05). The coincidence rates of malaria diagnosis and parasite species identification in different cities (prefectures) of Hubei Province were 71.43% to 100.00% and 50.00% to 100.00%, respectively, with significant differences among different regions (χ²=29.283, P<0.05). The coincidence rates of malaria diagnosis and parasite species identification were 72.73% to 100.00% and 0.00% to 100.00% in different diagnostic institutions, and the coincidence rate of species identification in hospitals (87.61%) was higher than that in Centers for Disease Control institutions (54.55%) (χ²=81.275, P<0.05). The coincidence rates of Plasmodium falciparum, P. vivax, P. malariae, and P. ovale identification were 91.50%, 88.57%, 80.00%, and 58.06%, respectively (χ²=19.777, P<0.05). Conclusion The quality of the qualitative diagnosis of malaria cases reported online from 2019 to 2022 is generally high. However, the ability of Plasmodium typing needs to be improved. In the future, technical training and quality control should be strengthened to improve the malaria surveillance capability during the post-elimination stage.

Background: Genetic defects in the human thyroid-stimulating hormone (TSH) receptor (TSHR) gene can cause congenital hypothyroidism (CH). However, the biological functions and comprehensive genotype–phenotype relationships for most TSHR variants associated with CH remain unexplored. We aimed to identify TSHR variants in Chinese patients with CH, analyze the functions of the variants, and explore the relationships between TSHR genotypes and clinical phenotypes. Methods: In total, 367 patients with CH were recruited for TSHR variant screening using whole-exome sequencing. The effects of the variants were evaluated by in-silico programs such as SIFT and polyphen2. Furthermore, these variants were transfected into 293T cells to detect their Gs/cyclic AMP and Gq/11 signaling activity. Results: Among the 367 patients with CH, 17 TSHR variants, including three novel variants, were identified in 45 patients, and 18 patients carried biallelic TSHR variants. In vitro experiments showed that 10 variants were associated with Gs/cyclic AMP and Gq/11 signaling pathway impairment to varying degrees. Patients with TSHR biallelic variants had lower serum TSH levels and higher free triiodothyronine and thyroxine levels at diagnosis than those with DUOX2 biallelic variants. Conclusions We found a high frequency of TSHR variants in Chinese patients with CH (12.3%), and 4.9% of cases were caused by TSHR biallelic variants. Ten variants were identified as loss-of-function variants. The data suggest that the clinical phenotype of CH patients caused by TSHR biallelic variants is relatively mild. Our study expands the TSHR variant spectrum and provides further evidence for the elucidation of the genetic etiology of CH.

Objective: To evaluate the anti-fatigue effects of different extracts from Cistanche tubulosa (Schenk) Wight (C. tubulosa, Rou Cong Rong), focusing on central and exercise-induced fatigue in mice. This study investigated the pharmacological effects of the total oligosaccharides, polysaccharides, and phenylethanoid glycosides (CPhGs) extracted from C. tubulosa. Methods: Models of sleep deprivation and forced swimming fatigue were established to simulate central and exercise-induced fatigue. The mice were treated with different extracts of C. tubulosa, and their effects were assessed using behavioral tests to measure exercise capacity, learning, and memory function. Biochemical analyses were performed to evaluate the changes in serum and brain neurotransmitter levels, liver and muscle glycogen storage, and various fatigue-related biomarkers. Results: This study found that treatment with C. tubulosa extract improved exercise capacity, learning, and memory in mice. Total oligosaccharides from C. tubulosa enhanced adrenocorticotropic hormone, cholinesterase, and thyroid-stimulating hormone levels, reduced cortisol levels in central fatigue models, and ameliorated biochemical markers of exercise-induced fatigue, including lowering lactic acid, blood urea nitrogen, and malondialdehyde levels. Among the tested extracts, the total oligosaccharides showed the most comprehensive anti-fatigue effects. Conclusion The anti-fatigue effects of C. tubulosa, particularly those of its total oligosaccharides, are pronounced in both central and exercise-induced fatigue. These effects are mediated by the regulation of neurotransmitter levels, enhancement of glycogen storage, and improvement of antioxidant enzyme activity, suggesting potential therapeutic benefits in fatigue-related conditions.

Aim To establish the fingerprint of raw bupleurum and vinegar bupleurum,investigate the difference in their anti-liver fibrosis effects,and ex-plore the relationship between the chemical composition of raw bupleurum and vinegar bupleurum and their an-ti-liver fibrosis efficacy.Methods The fingerprints of 10 batches of raw bupleuri and 10 batches of bupleuri were established by UPLC method.The liver fibrosis cell model in vitro was established by TGF-β induced LX-2 hepatic stellate cells.The liver fibrosis cell mod-el was analyzed with collagen type Ⅰ(col1a1)and α-smoothmuscleactin.The expression of α-SMA protein was used as the pharmacodynamic index.MetaboAna-lyst5.0 was used to screen the difference markers af-fecting the quality of raw bupledges and vinegar bu-pledges with VIP value＞1 as the criterion.Orthogo-nal partial least squares discriminant analysis(OPLS-DA)was used to screen the main components of raw bupleurum and vinegar bupleurum against liver fibro-sis.Results There were 18 peaks in the UPLC fin-gerprints of raw bupleurum and vinegar bupleurum,and the analysis results showed that there were nine main differences between raw bupleurum and vinegar bupleurum,among which peaks 9,7 and 6 could be considered as bupleurin d,bupleurin a and bupleurin f.The results of spectral effect relationship showed that the main components of bupleurum anti-liver fibrosis were peaks 11,12,14,15 and 18.Conclusions The established fingerprint method of raw bupleurum and vinegar bupleurum is simple and feasible,and the important components of anti-liver fibrosis activity are screened through the spectrum effect relationship,which provides a basis for clarifying the material basis of anti-liver fibrosis effect of raw bupleurum and vine-gar bupleurum.

Objective:To investigate the current status of sarcopenia and self-management in elderly patients with type 2 diabetes mellitus (T2DM), and to explore the identification of risk factors for sarcopenia by diabetes self-management ability.Methods:Using convenience sampling, 284 elderly patients with T2DM who visited a community health service center in Beijing from March to September 2023 were selected as subjects. The patients were screened for sarcopenia and received related health examinations based on Asian working group for sarcopenia (AWGS) 2019 Consensus. Surveys were conducted using general information questionnaire, the Summary of Diabetes Self-Care Activities measure, and other questionnaires. Patients were divided into groups according to the presence or absence of muscle attenuation (defined as suspected and confirmed sarcopenia).Results:The prevalence of muscle attenuation in the 284 elderly patients with T2DM was 48.9%, and the prevalence of sarcopenia was 15.9%. The proportions of females, patients who are over 70 years old, and patients with a sedentary lifestyle were significantly higher in the group with muscle attenuation compared with the group without muscle attenuation. High-quality protein intake, extremity skeletal muscle mass index, grip strength, and six-meter walking speed were significantly lower in the muscle attenuation group. Binary logistic regression analysis revealed that age, alcohol consumption, a sedentary lifestyle, and high-quality protein intake were influencing factors for sarcopenia in elderly patients with T2DM ( P<0.05). The total self-care scores and subtotals in exercise domains showed significant differences ( P<0.05) between patients with and without muscle attenuation. Univariate analysis indicated significant differences in self-management behaviors among patient groups stratified by grip strengths and 6-meter walk speeds ( P<0.05). Multivariate linear regression analysis showed that grip strength and 6-meter walk speed were influencing factors for exercise management behaviors in elderly patients with T2DM ( P<0.05). Conclusions The prevalence of sarcopenia in elderly patients with T2DM is relatively high, and their level of diabetes self-management is medium to low. Practitioners should pay extra attention to patients who are over 70 years old, with sedentary habits, with low intake of high-quality protein, and females. It's recommended to use grip strength and 6-meter walk speed tests as initial screening tools for sarcopenia in elderly patients with T2DM, in order to identify risks early and implement targeted health management to promote the development of good self-management behaviors among patients.

Objective To explore the relationship between anxiety sensitivity and psychological stress before parachuting training among parachuting trainees and the mediating role of resilience between them.Methods Anxiety sensitivity index scale(version 3),resilience scale,psychological stress self-evaluation test and self-compiled general information questionnaire were employed for 258 parachuting trainees before training.Pearson correlation analysis was used to analyze the correlations among anxiety sensitivity,resilience and psychological stress.A multiple linear regression analysis was conducted with anxiety sensitivity and resilience as independent variables and psychological stress as dependent variable to explore the relationships among these 3 factors.The mediating effect of resilience on the relationship between anxiety sensitivity and psychological stress was examined using the Hayes Process macro program and bias corrected non-parametric percentile Bootstrap method.Results Before parachuting training,the prevalence of psychological stress among parachuting trainees was 5.0%(13/258).The correlations between anxiety sensitivity,resilience and psychological stress were significant(all P＜0.01).Anxiety sensitivity was positively associated with psychological stress among parachuting trainees(b=0.412,t=7.062,P＜0.01),while resilience was negatively associated with psychological stress(b=-0.187,t=-3.722,P＜0.01).Anxiety sensitivity and resilience were found to explain 31.4%of the total variance.Resilience partially mediated the effect of anxiety sensitivity on psychological stress,accounting for 20.48%of the total effect.Conclusion Parachuting trainees are at a relatively low stress level,with good psychological adaptation.Resilience plays a partial mediating role in the association between anxiety sensitivity and psychological stress.More attention should be paid to parachuting trainees with high anxiety sensitivity,enhancing their resilience,and reducing psychological stress before parachuting training.

Objective:To investigate the safety and efficacy of the TRIANGLE operation after neoadjuvant chemotherapy in locally advanced pancreatic cancer(LAPC).Methods:This study is a retrospective case series analysis. Between January 2020 and December 2022, a total of 103 patients were diagnosed as LAPC who underwent neoadjuvant chemotherapy at the Pancreas Center, the First Affiliated Hospital of Nanjing Medical University. Among them, 26 patients (25.2%) underwent the TRIANGLE operation. There were 15 males and 11 females,with a age of (59±7) years (range: 49 to 74 years). The pre-treatment serum CA19-9( M(IQR)) was 248.8(391.6)U/ml (range: 0 to 1 428 U/ml),and the serum carcinoembryonic antigen was 4.1(3.8)μg/L(range: 1.4 to 13.4 μg/L). The neoadjuvant chemotherapy regimens included: mFOLFIRINOX regimen in 6 cases(23.1%), GnP regimen in 14 cases(53.8%), and mFOLFIRINOX+GnP regimen in 6 cases(23.1%). The follow-up duration extended until June 2023 or until the occurrence of the patient′s death or loss to follow-up. The Kaplan-Meier method was employed to estimate the 1-year and 3-year overall survival rates. Results:After neoadjuvant chemotherapy,CA19-9 levels decreased by 92.3(40.1)%(range:2.1% to 97.7%). Evaluation of the response to treatment revealed 13 cases(50.0%) of stable disease,11 cases(42.3%) of partial response,and 2 cases(7.7%) of complete response. The surgical operation consisted of 12 cases(46.2%) of pancreaticoduodenectomy,12 cases(46.2%) of distal pancreatectomy,and 2 cases(7.7%) of total pancreatectomy. Margin determination was based on the “standardised pathology protocol” and the “1 mm” principle. No R2 and R1(direct) resections were observed,while the R0 resection rate was 61.5%(16/26), and the R1(1 mm) resection rate was 38.5%(10/26).The R1(1 mm) resection rates for the anterior margin,posterior margin,transected margin,portal vein groove margin,and uncinate margin were 23.1%(6/26),19.2%(5/26),12.5%(3/24),2/14, and 1/12, respectively. The overall postoperative complication rate was 57.8%(15/26),with major complications including grade B/C pancreatic fistula 25.0%(6/24,excluding 2 cases of total pancreatectomy),delayed gastric emptying in 23.1%(6/26),wound complications 11.5%(3/26),postoperative hemorrhage 7.7%(2/26), chylous fistula 7.7%(2/26) and bile fistula 3.8%(1/26). No reoperation was performed during the perioperative period(<90 days). One patient died on the 32 nd day postoperatively due to a ruptured pseudoaneurysm. A total of 25 patients were followed up,with a follow-up time of 21(24)months(range: 8 to 42 months). During the follow-up period,8 cases(32.0%) died due to tumor recurrence and metastasis,while 17 patients(68.0%) remained alive,including 11 cases of disease-free survival,5 cases of distant metastasis,and 1 case of local recurrence. The overall survival rates at 1- and 3-year after the initiation of neoadjuvant chemotherapy were 95.8% and 58.9%, respectively. The overall survival rates at 1- and 3-year after surgery were 77.7% and 57.8%, respectively. Conclusion:Performing pancreatoduodenectomy according to the Heidelberg triangle protocol in LAPC patients after neoadjuvant chemotherapy might increase the R0 resection rate without increasing perioperative mortality or the incidence of major postoperative complications.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To investigate the effect of left bundle branch area pacing(LBBaP)on new-onset atrial fibrillation(NOAF)and atrial high rate episodes(AHREs)in patients with atrioventricular block(AVB).Methods Eighty-four patients with Ⅲ°AVB for pacemaker implantaion were divided into the LBBaP group(n=42)and the RVSP group(n=42)based on the site of the ventricular leads.The two groupswere compared in terms of the pre-and post-operative QRSd,ventricular pacing parameters,complications,incidence of stroke,NOAF and AHREs.Results(1)The incidence of postoperative NOAF and AHREs in the LBBaP group was significantly lower compared with RVSP group(P<0.05).(2)The p-QRSd in the LBBaP group was significantly shorter compared with RVSP group(P<0.05).(3)The two groups showed no significant differences in ventricular pacing parameters,incidence of complications and stroke events(P>0.05).Conclusion LBBaP is superior to right ventricular pacing in reducing the incidence of postoperative AHREs and NOAF in patients after implantation and improving the prognosis of patients.
