Objective:To explore the clinical application of mobile-intelligent medical management system for gout patients.Methods:This study was a randomized controlled trial. One hundred and two patients with gout who visited rheumatology department of the First Hospital of Jilin University from January 2022 to October 2023 were randomly divided into study group ( n=53) and the control group ( n=49). Patients in the study group were managed by the mobil-gout(M-G) health management system which consists of a distant management plateform and an App. The body weight and blood uric acid levels were regularly self-tested by patients, and the information was sent to the system, the doctor gave feed-back advice on medication adjustment and dietary management every 2 weeks. While patients in the control group were managed following the conventional outpatient consultation mode. The serum uric acid levels, liver and kidney function tests and physical examinations were conducted on the day of enrollment and 3 and 6 months after treatment. The number of affected joints and the frequency of attacks were evaluated, and pain was assessed using the visual analog scale (VAS). The efficacy of treatment were compared between two groups. Results:After 3 and 6 months of treatment, the serum uric acid levels in study group were significantly lower than those in control group (408.0 (345.0, 450.0)μmol/L vs. 458.0 (409.0, 482.0)μmol/L, 371.0 (338.5, 409.0) μmol/L vs. 412.0 (368.5, 445.0)μmol/L; Z=3.37, 4.61, P<0.01); and VAS scores were also significantly lower than those in control group (6.66±1.46 vs. 4.68±1.80, 7.45±1.06 vs. 5.88±1.52; t=14.12, 13.72, P<0.01). After 6 months of treatment, the frequency of gout attacks in the study group was significantly lower than that in the control group ( χ2=9.30, P<0.05). As the follow-up period was extended, the average number of joints affected by gout attacks and the frequency of gout attacks in the study group showed a reducing trend compared to the control group, but the differences were not statistically significant ( P>0.05). Conclusions:The M-G medical management system can more effectively control uric acid levels and alleviate symptome for gout patients.

Objective: To explore the clinical characteristics and prognostic factors of female patients with Stanford type B aortic dissection. Methods: This is a single-centre retrospective study. Consecutive patients diagnosed with Stanford type B aortic dissection in General Hospital of Northern Theater Command from June 2002 to August 2021 were enrolled, and grouped based on sex. According to the general clinical conditions and complications of aortic dissection tear, patients were treated with thoracic endovascular aortic repair, surgery, or optimal medication. The clinical characteristics and aortic imaging data of the patients at different stages were collected, adverse events including all-cause deaths, stroke, and occurrence of aortic-related adverse events were obtained during hospitalization and within 30 days and at 1 and 5 years after discharge. According to the time of death, death was classified as in-hospital death, out-of-hospital death, and in-hospital death was divided into preoperative death, intraoperative death and postoperative death. According to the cause of death, death was classified as aortic death, cardiac death and other causes of death. Aortic-related adverse events within 30 days after discharge included new paraplegia, post-luminal repair syndrome, and aortic death; long-term (≥1 year after discharge) aortic-related adverse events included aortic death, recurrent aortic dissection, endoleak and distal ulcer events. The clinical characteristics, short-term and long-term prognosis was compared between the groups. Logistic regression analysis was used to explore the association between different clinical factors and all-cause mortality within 30 days in female and male groups separately. Results: A total of 1 094 patients with Stanford type B aortic dissection were enrolled, mean age was (53.9±12.1) years, and 861 (78.7%) were male and 233 (21.3%) were female. (1) Clinical characteristics: compared with male patients, female patients were featured with older average age, higher proportion of aged≥60 years old, back pain, anemia, optimal medication treatment, and higher cholesterol level; while lower proportion of smoking and drinking history, body mass index, calcium antagonists use, creatine kinase level, and white blood cell count (all P<0.05). However, there was no significant difference in dissection tear and clinical stage, history of coronary heart disease, diabetes, hypertension, and cerebrovascular disease between female and male patients (all P>0.05). (2) Follow-up result: compared with male patients, female patients had a higher rate of 30-day death [6.9% (16/233) vs. 3.8% (33/861), P=0.047], in-hospital death (5.6% (13/233) vs. 2.7% (23/861), P=0.027), preoperative death (3.9% (9/233) vs. 1.5% (12/861), P=0.023) and aorta death (6.0% (14/233) vs. 3.1% (27/861), P=0.041). The 1-year and 5-year follow-up results demonstrated that there were no significant differences in death, cerebrovascular disease, and aorta-related adverse events between the two groups (all P>0.05). (3) Prognostic factors: the results of the univariate logistic regression analysis showed that body mass index>24 kg/m² (HR=1.087, 95%CI 1.029-1.149, P=0.013), history of anemia (HR=2.987, 95%CI 1.054-8.468, P=0.032), hypertension (HR=1.094, 95%CI 1.047-1.143, P=0.040) and troponin-T>0.05 μg/L (HR=5.818, 95%CI 1.611-21.018, P=0.003)were associated with an increased risk of all-cause mortality within 30 days in female patients. Conclusions: Female patients with Stanford type B aortic dissection have specific clinical characteristics, such as older age at presentation, higher rates of anemia and combined back pain, and higher total cholesterol levels. The risk of death within 1 month is higher in female patients than in male patients, which may be associated with body mass index, hypertension, anemia and troponin-T, but the long-term prognosis for both female and male patients is comparable.

Objective: To explore the combination of metabolism-related chronic diseases associated with the prevalence of non-alcoholic fatty liver disease (NAFLD) in community residents in Shanghai. Methods: The baseline data of Shanghai Suburban Adult Cohort and Biobank were used to understand the prevalence of five metabolism-related chronic diseases, including obesity, hypertension, hyperlipidemia, gout and diabetes, based on questionnaire survey, physical examination and blood biochemical detection. NAFLD was diagnosed by B-ultrasound detection and questionnaire. Multivariable logistic regression model was used to analyze the association of 31 metabolism-related chronic diseases combinations with the prevalence of NAFLD. Results: The median age (Q₁, Q₃) of 65 477 subjects was 60 (51, 66) years, and men accounted for 40.6%. The overall prevalence of NAFLD was 38.2%, and the prevalence of HAFLD in patients without any of the five metabolism-related chronic diseases was 12.0%. The chronic disease combination with the strongest association with NAFLD was obesity + hypertension + hyperlipidemia + gout + diabetes in the total population (OR=37.94, 95%CI: 31.02-46.41), in women (OR=36.99, 95%CI: 28.78-47.54) and in age group ≥60 years (OR=36.19, 95%CI: 28.25-46.36). The chronic disease combination with the strongest association with NAFLD was obesity + hyperlipidemia + gout + diabetes in men (OR=50.70, 95%CI: 24.62-104.40) and in age group <60 years (OR=49.58, 95%CI: 24.22-101.47). Conclusions: The prevalence of NAFLD in community residents in Shanghai was high. Attention needs to be paid to health of obese people and weight loss should be promoted for them. Community health education should be strengthened for patients complicated with gout, diabetes, hyperlipidemia and hypertension and it is necessary to correct abnormal serum uric acid, blood sugar, blood lipids and blood pressure in a timely manner to reduce the risk of NAFLD.

Objective: To investigate the clinical manifestations and genetic features of 2 children with Smith-Kingsmore syndrome caused by MTOR gene variation and review the literature. Methods: The clinical data of 2 children carrying MTOR gene variant, diagnosed at Xi'an Children's Hospital from April 2018 to April 2021, were retrospectively summarized."MTOR"and"Smith-Kingsmore syndrome"were used as key words to search at China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, PubMed and OMIM up to August 2021. The characteristics of MTOR gene variation and the clinical phenotype of children with Smith-Kingsmore syndrome were summarized. Results: Two children were both females, aged 1.5 years and 2 years respectively, the onset age were both in infancy. They both had developmental delay, megalencephaly and abnormal face. Both whole exome sequencing revealed a de novo heterozygous missense variant in MTOR gene. One case carried c.5395G>A (p.Glu1799Lys) and the other case carried c.7234G>C (p.Asp2412His). There was no literature of MTOR gene variation in Chinese. So far, a total of 45 cases were reported worldwide with detailed clinical information. Eleven variations in MTOR gene were involved, which were all heterozygous missense mutations. Among them, p.Glu1799Lys was the most common sites (28 cases,62%). Another case carried c.7234G>C (p.Asp2412His) was not reported before. Summarizing the 47 cases (including these 2 cases), 46 cases had developmental delay or intellectual disability, 9 cases had developmental regression,42 cases had megalencephaly, 30 cases had facial malformation,16 cases had hypotonia, 17 cases had autism spectrum disorders, 3 cases had hyperactivity, 3 cases had obsessive compulsive disorder, 13 cases had eye diseases, 11 cases had cutaneous vascular malformation, and 9 cases had hypoglycemia. Conclusions: The main clinical features of Smith-Kingsmore syndrome include megalencephaly, developmental delay or intellectual disability, and facial malformation, which can be combined with epilepsy, autism spectrum disorder, hypotonia, hypoglycemia and so on. The variation of MTOR gene is the cause of Smith-Kingsmore syndrome.

The present study clarified the molecular mechanism of curcumol against liver fibrosis based on its effects on the autopha-gy and apoptosis of hepatic stellate cells. The hepatic stellate cells were divided into a blank control group, a transforming growth factor-β1(TGF-β1)(10 ng·mL~(-1)) group, and low-(12.5 mg·L~(-1)), medium-(25 mg·L~(-1)), and high-dose(50 mg·L~(-1)) curcumol groups. The effect of curcumol on the viability of hepatic stellate cells induced by TGF-β1 was detected by the MTT assay kit. The apo-ptosis in each group was determined by flow cytometry. Real-time fluorescence-based quantitative PCR(RT-PCR) was employed for the detection of mRNA expression of α-smooth muscle actin(α-SMA), type Ⅰ collagen(collagen Ⅰ), and type Ⅲ collagen(collagen Ⅲ). Western blot was used to detect the protein expression of p62, microtubule-associated protein 1 light chain 3(LC3), beclin1, B cell lymphoma 2(Bcl-2), and Bcl-2-associated X protein(Bax). Transmission electron microscopy(TEM) was used to observe cell morphology and autophagosome formation in each group. The autophagic flux was observed after cell infection with adenovirus under double fluorescence labeling. The cell viability assay revealed that compared with the TGF-β1 group, the curcumol groups showed significantly decreased cell viability. The apoptosis assay showed that the apoptosis rates of the curcumol groups were significantly higher than that of the TGF-β1 group. RT-PCR indicated that the mRNA expression of α-SMA, collagenⅠ, and collagen Ⅲ in the curcumol groups was significantly lower than that of the TGF-β1 group. Western blot showed that the expression of p62, LC3, beclin1, Bcl-2, and Bax in the curcumol groups was significantly different from that in the TGF-β1 group. As demonstrated by TEM, compared with the TGF-β1 group, the curcumol groups showed significantly increased autophagosomes. The detection of autophagic flow by the adenovirus under double fluorescence labeling showed that autolysosomes in the curcumol groups were significantly increased compared with those in the TGF-β1 group. Curcumol can induce the autophagy and apoptosis of hepatic stellate cells, which may be one of its anti-liver fibrosis mechanisms.

Weeds is one of the important parts of agricultural ecosystem of Chinese materia medica. Weeds is a double-edged sword with advantages and disadvantages for the cultivated medicinal plants. In this study, we firstly analyzed the positive and negative effects of weeds on the yield and quality of Chinese materia medica. We then explored the possible mechanisms for the weeds' positive effects from the aspects of interspecific relationship, soil microecological environment, light environment, natural control of pests and so on. We also summarized three basic principles of weed control, that is, "making medicinal plants and weeds coexist harmoniously, achieving the overall optimum growth of medicinal plants", "prevention first, integrated control" and "preserving beneficial weeds and increasing their beneficial effects, removing harmful weeds and control their adverse effects". Finally, we introduced several common weed ecological control technology in field of the cultivated medicinal plants in China, including technology of controlling weeds by no-tillage, stral mulch, rotation, alternative herbs, competitive crops, and allelopathy. This study is aimed to apply the ecology theory to guide weed management and control, so as to achieve the goal of advantages promotion and disadvantages elimination of weeds to cultivated medicinal plants, making weeds into treasure and to promote the sustainable and healthy development of Chinese medicinal materials production and the protection of weed diversity.
