The paper introduces the diagnostic and therapeutic ideas and clinical experience of Professor LIU Zhibin in treatment with acupuncture for Parkinson's disease with mild cognitive impairment. Professor LIU believes that the basic pathogenesis of Parkinson's disease with mild cognitive impairment refers to the deficiency of liver and kidney, and the loss of mind control. Therefore, the treatment focuses on nourishing the liver and kidney, regulating the governor vessel, opening the brain orifice, and regulating the mind. The point prescription is composed of Tongdu Tiaoshen zhen (the points for promoting the circulating of the governor vessel and regulating the mind, i.e. four-mind needles [Extra], Shenting [GV24], bilateral Benshen [GB13] and Fengfu [GV16]), xiusanzhen (three-olfaction needles, including bilateral Yingxiang [LI20] and Yintang [GV24⁺]) and zhichan bazhen (eight anti-tremble needles, i.e. Baihui [GV20], Lianquan [CV23], and Hegu [LI4], Waiguan [TE5], Taichong [LR3], Zusanli [ST36], Sanyinjiao [SP6] and Taixi [KI3] on the affected side). Besides, the prescription is modified according to the syndrome, and the special technique of bone-touching needling is combined to enhance the therapeutic effect.

Objective:To assess the goal fulfillment in terms of blood glucose, blood pressure, blood lipid, and the composite indicator of these three in patients with diabetes who received intensified treatment at Peking Union Medical College Hospital and regular follow-up for 12 months, analyze the influencing factors, and explore the comprehensive management model for intensive diabetes treatment outpatient services.Methods:This study was a prospective, observational cohort study. The diabetes patients who received long-term regular follow-up at the intensive diabetes treatment outpatient clinic of Peking Union Medical College Hospital from 2012 to 2023 were selected as the research subjects. They were followed up and clinical data were collected at the 1st, 3rd, 6th, 9th, and 12th months of follow-up. The study assessed the goal fulfillment rates in terms of blood glucose, blood pressure, blood lipid, and the composite indicator of these three, with the goals of glycated hemoglobin (HbA1c)<7%, blood pressure<130/80 mmHg, and low-density lipoprotein cholesterol (LDL-C)<2.6 mmol/L. The study also analyzed the impact of factors, including gender, age, type of diabetes, duration of diabetes, body mass index, comorbidities, complications, and treatment regimens, on the outcomes of comprehensive diabetes management.Results:A total of 232 patients were included in the study, of whom 210 were with type 2 diabetes (90.5%), 13 with type 1 diabetes (5.6%), 5 with latent autoimmune diabetes of the adult (2.2%), 3 with diabetes after total pancreatectomy (1.3%), and 1 with mitochondrial diabetes (0.4%). After 3 months of intensified management, the goal fulfillment rates of blood glucose (67.7% vs. 34.1%, Kappa=0.336, P<0.001), blood pressure (53.4% vs. 37.5%, Kappa=0.159, P=0.001), blood lipid (59.1% vs. 39.2%, Kappa=0.198, P<0.001), and the composite indicator (20.7% vs. 3.0%, Kappa=0.177, P<0.001) were significantly increased. Continued treatment at 6, 9, and 12 months showed stable and sustained increases in the goal fulfillment rates of blood glucose, blood pressure, blood lipid, and the composite indicator. Logistic regression analysis showed that baseline hyperglycemia ( P=0.002), disease duration ≥5 years ( P<0.001), smoking ( P=0.009), alcohol consumption ( P=0.038), presence of diabetic complications ( P=0.001), combination therapy with oral antidiabetic drugs and insulin ( P<0.001), and use of antiplatelet drugs ( P=0.037) were risk factors for uncontrolled HbA1c. Baseline hypertension ( P<0.001), alcohol consumption ( P=0.030), and comorbid dyslipidemia ( P=0.028) were risk factors for uncontrolled blood pressure. Baseline uncontrolled LDL-C ( P=0.020) and non-use of statins ( P<0.001) were risk factors for uncontrolled blood lipid. Conclusions:Among patients with the long-term follow-up at our intensive diabetes treatment clinic, the goal fulfillment rates of blood glucose, blood lipid, blood pressure, and the composite indicator of these three are relatively higher. However, it is still necessary to improve patient compliance as much as possible, emphasize weight management, and persist on the comprehensive diabetes treatment.

Objective:To investigate the characteristics of gut microbiota in patients with type 2 diabetes (T2DM) complicated by nonalcoholic fatty liver disease (NAFLD).Methods:A total of 74 patients first diagnosed with T2DM at the Endocrinology Department of Peking Union Medical College Hospital from April 2021 to October 2023 were included. Among them, 28 patients had concurrent NAFLD while 46 patients did not. Additionally, 51 healthy controls were matched (HC group). Clinical laboratory parameters were collected, and 16S rRNA sequencing with fecal samples was conducted to compare the differences in gut microbiota across the groups.Results:Compared to the group with T2DM, patients with concurrent T2DM and NAFLD were younger, had higher level of insulin resistance as assessed by the homeostatic model assessment of insulin resistance, higher body mass index (BMI), and higher triglyceride levels. There was no difference in α-diversity across the three groups ( P>0.05), while there was a significant difference in β-diversity ( P=0.03). The Eubacterium coprostanoligenes, Fusicatenibacter, Parasutterella and Tyzzerella 3 were enriched in the group with concurrent T2DM and NAFLD as shown by the relative abundance, while the relative abundance of Flavonifractor was decreased in this group. Tyzzerella 3 abundance was positively correlated with triglyceride and albumin levels and negatively correlated with high-density lipoprotein cholesterol (HDL-C) levels. Conclusion:Patients with T2DM complicated by NAFLD exhibit dysbiosis in gut microbiota composition and specific genera abundance, with Flavonifractor identified as a potential protective factor for T2DM complicated by NAFLD.

Objective:To investigate the predictive performance of triglyceride and triglyceride glucose (TyG) index in the first trimester for the onset of gestational diabetes mellitus (GDM).Methods:Pregnant women who visited Beijing Chaoyang Maternal and Child Health Care Hospital and Beijing Haidian Maternal and Child Health Care Hospital from 2019 to 2022 were prospectively included. Concurrently, 78 healthy non-pregnant women who visited the Department of Endocrinology of Peking Union Medical College Hospital were included. The clinical characteristics and laboratory biomarkers including fasting blood glucose and blood lipid profiles were collected at the first visit in early pregnancy. Oral glucose tolerance test (OGTT) was performed at 24-28 weeks of gestation for GDM screening. Multivariate Logistic regression analysis was used to determine the association between biomarkers in early pregnancy and the risk of GDM. The receiver operating characteristic curve was used to evaluate the predictive performance and to identify the optimal cut-off value of triglyceride and TyG index in the first trimester for the risk of GDM.Results:A total of 1 677 pregnant women were included in this study, and the prevalence of GDM in our cohort was 19.6%. Compared with women who did not develop GDM, women with GDM showed an older maternal age, higher pre-pregnancy body mass index, and increased levels of laboratory biomarkers including fasting blood glucose, fasting insulin, total cholesterol, triglyceride, low-density lipoprotein cholesterol, TyG index, and Homeostasis Model Assessment of Insulin Resistance ( P<0.001). Logistic regression analysis showed that both triglyceride and TyG index in the first trimester were independent risk factors for GDM. The optimal cut-off values of triglyceride and TyG index for predicting the risk of GDM were 0.93 mmol/L and 8.10, respectively. The predictive performance can be further improved if maternal age and pre-pregnancy BMI are included. Conclusion:Triglyceride and TyG index in early pregnancy are closely associated with the risk of GDM, and can be used as early predictors of GDM.

There are few reports in China on the laparoscopic Burch procedure in the treatment of female stress urinary incontinence. Twenty-two female stress urinary incontinence patients admitted to our hospital were treated with laparoscopic Burch procedure, with an overall effective rate of 100%. The score of the International Continence Advisory Committee Urinary Incontinence Questionnaire-Short Form (ICI-Q-SF) at one month after treatment was lower compared to that before the procedure. There were no complications during two months of follow-up.

Objective:To investigate the expression of complement C3 in serums and tissues of lung adenocarcinoma patients with brain metastases and the mechanism of complement C3 in inducing epithelial mesenchymal transition (EMT).Methods:The retrospective case-control study, cell experiments and animal experiments were conducted. The serum samples from 20 healthy examinees, 20 advanced lung adenocarcinoma patients without brain metastases and 20 advanced lung adenocarcinoma patients with brain metastases at the First People's Hospital of Yancheng from January 2021 to January 2023 were collected, and the expression of complement C3 in serum samples was detected by immunoturbidimetry. At the same time, lung tissue samples were collected from 10 lung adenocarcinoma patients without brain metastases, and lung tissue and brain tissue samples were collected from 10 lung adenocarcinoma patients with brain metastases in the First People's Hospital of Yancheng. Immunohistochemistry was used to detect the expression of complement C3, C3aR, Kruppel like factor 5 (KLF5), and N-cadherin (N-cad) in the tissue samples. Using lentivirus to construct a human lung adenocarcinoma with brain metastases cell line PC14-C3 with stable overexpression of complement C3, with cells infected with empty vector virus as the control group (PC14-Ctrl). Western blotting was used to detect the expression of complement C3, KLF5, N-cad, and E-cadherin (E-cad) in PC14-C3 and PC14-Ctrl cells, and scratch assay was used to assess cell migration ability. Using the random number table method, 12 BALB/c nude mice were evenly divided into PC14-C3 group and PC14-Ctrl group. PC14-C3 cells and PC14-Ctrl cells were subcutaneously inoculated on the ventral side, and the body mass and tumor volume of the nude mice were recorded. Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression of KLF5, N-cad and E-cad mRNA in various tumor cells and tumor tissues of nude mice.Results:The serum complement C3 levels in healthy individuals, lung adenocarcinoma patients without brain metastases and lung adenocarcinoma patients with brain metastases were (1.14±0.17) g/L, (1.20±0.15) g/L and (1.61±0.21) g/L, respectively. The serum complement C3 level in lung adenocarcinoma patients with brain metastases was higher than that in lung adenocarcinoma patients without brain metastases and healthy individuals, and the differences were statistically significant (both P < 0.001). The results of immunohistochemical testing showed that the proportions of positive expression areas of complement C3, C3aR, KLF5, and N-cad proteins in the lung primary lesions of lung adenocarcinoma patients with brain metastases were higher than those of patients without brain metastases, and the differences were statistically significant (all P < 0.05). The mRNA ( P < 0.05) and protein expression levels of complement C3 in PC14-C3 cells were higher than those in PC14-Ctrl cells, indicating successful transfection. The scratch assay results showed that the migration rate of PC14-Ctrl cells was (37.5±4.1)%, and the migration rate of PC14-C3 cells was (60.4±2.9)%, and the difference was statistically significant ( t = 7.86, P < 0.01). The relative expressions of EMT promoting molecules KLF5 and N-cad mRNA in PC14-C3 cells were higher than those in PC14-Ctrl cells, while the relative expression of EMT inhibiting molecule E-Cad mRNA was lower than that in PC14-Ctrl cells, and the differences were statistically significant (all P < 0.05). On the 26th day of tumor loading, the tumor volume of nude mice in PC14-C3 group was (610±10) mm 3, while that of PC14-Ctrl group was (321±30) mm 3; the body mass of nude mice in PC14-C3 group was lower than that in PC14-Ctrl group [(21.6±0.6) g vs. (23.2±0.6) g], and the differences were statistically significant (both P < 0.05). At the end of the experiment, 5 nude mice died and 1 survived in the PC14-C3 group; 1 nude mouse died and 5 survived in the PC14-Ctrl group. The relative expressions of KLF5 and N-cad mRNA in the tumor tissues of nude mice in PC14-C3 group were higher than those in PC14-Ctrl group, while the relative expression of E-Cad mRNA was lower than that in PC14-Ctrl group, and the differences were statistically significant (all P < 0.05). Conclusions:Lung adenocarcinoma patients with brain metastases have high levels of complement C3 in their serums and primary lesions. Complement C3 may induce EMT and promote the occurrence of lung adenocarcinoma brain metastases by affecting the expressions of KLF5, N-cad and E-cad.

Objective:The decline in nutritional status in patients with severe pneumonia may contribute to an increase in in-hospital mortality. Enteral nutrition support can improve the nutritional status of patients, and is relatively easy to manage, with low cost and fewer serious complications. On the other hand, adverse reactions such as gastric retention and gastric microbiota translocation may increase the incidence of nosocomial pneumonia and increase the uncertainty of patient prognosis. There is no predictive model for in-hospital death in severe pneumonia patients receiving enteral nutrition support. The objective of this study was to investigate the risk factors of in-hospital death in patients with severe pneumonia receiving enteral nutrition support and to establish a prognostic model for such patients.Methods:This was a single-center retrospective study. Patients with severe pneumonia who were hospitalized in Peking Union Medical College Hospital and received enteral nutrition support were included from January 1, 2015 to December 31, 2020. The primary endpoints were in-hospital mortality rate and unordered discharge rate. The independent risk factors were determined using univariate and multifactorial logistic regression analysis, the nomogram scoring model was constructed, and the decision curve analysis (DCA) was performed.Results:A total of 632 severe pneumonia patients who received enteral nutrition support were included. Patients were divided into death and survival groups according to the presence or absence of in-hospital death, and 24 parameters were found with significant differences between groups. Nine parameters were independent predictors of mortality, namely the duration of ventilator use, the presence of malignant hyperplasia diseases, the maximal levels of platelet and prothrombin during hospitalization, and the nadir levels of alanine aminotransferase, serum albumin, sodium, potassium, and blood glucose. Based on these variables, a risk prediction scoring model was established (ROC = 0.782; 95% CI: 0.744 to 0.819, concordance index: 0.772). Calibration curves, DCA, and clinical impact curve were plotted to evaluate the goodness of function, accuracy, and applicability of the predictive nomogram, using the training and test sets. Conclusion:This study summarized the clinical characteristics of patients with severe pneumonia receiving enteral nutrition support and developed a scoring model to identify risk factors and establish prognostic models.

Objective:To explore the relationship between respiratory mechanics and right heart function during ARDS mechanical ventilation through the establishment of Beagle dogs acute respiratory distress syndrome (ARDS) animal model and the application of different levels of mechanical ventilation, which will provide theoretical basis for right heart protective ventilation strategy of ARDS.Methods:Beagle dogs were anesthetized successfully and then pulmonary artery floating catheter, esophageal manometric catheter and femoral artery catheter were inserted. Under the pressure control mode, the driving pressure was fixed. After adjustment, PEEP gradually increased from 2 cmH 2O to 14 cmH 2O. The changes of respiratory mechanics, hemodynamics and right heart function were observed. ARDS model was established by injecting oleic acid into central vein, and mechanical ventilation with the same parameters was given after the model was established successfully. In contrast to itself, the changes of respiratory mechanics, hemodynamics and right heart function indexes of experimental dogs before and after modeling were analyzed. In the group, the indexes of different PEEP were compared by ANOVA, and then compared by Student-Newman-Keuls. The difference was statistically significant at a P value <0.05. Results:Before modeling, the peak airway pressure (P peak) and plateau pressure (P plat) increased with the increase of PEEP ( F=232.733,196.33, P<0.05). However, P trans-I, P trans-E, C stat and Vt decreased significantly ( F=4.524, 6.499, 64.803, 2.31, P<0.05). The area of change of right ventricle (FAC) became smaller ( F=3.09, P<0.05); SV first increased and then decreased ( F=3.24, P<0.05), and CVP and MPAP increased ( F=19.07,14.81, P<0.05). There was no significant difference in TAPSE, MAP, HR and SpO 2 ( P>0.05). After modeling, as PEEP increased, P peak, P plat, P ES-I and P ES-E increased significantly ( F=24.829, 41.95, 9.78, 87.86, P<0.05). Vt, P trans-I, P trans-E, C stat and Vt first increased and then decreased ( F=2.91, 4.29, 5.84, 48.890, P<0.05). TAPSE and SV first increased and then decreased ( F=6.22,6.54, P<0.05). CVP and MPAP increased ( F=5.23, 19.24, P<0.05). MAP increased first and then decreased ( F=5.02, P<0.05). SpO 2 increased ( F=2.77, P<0.05). FAC and HR had no statistical significance ( P>0.05). Conclusions:Trans pulmonary pressure and lung compliance can reflect the effectiveness of ARDS lung recruitment, and have good synergy; with the increase of PEEP, the right ventricular systolic function TAPSE is first affected, and SV compensatory increase, but with the increase of PEEP, TAPSE and SV decrease; pulmonary blood flow distribution is more important in improving alveolar oxygenation. Therefore, real-time monitoring of trans pulmonary pressure, TAPSE and intrapulmonary blood flow should be performed in ARDS treatment.

Gut microbiota is considered as the cornerstone of maintaining the health of human host, because it not only helps to obtain nutrition and energy from the food, but also regulates the energy metabolism through the metabolites produced, which plays an important role in the occurrence and development of various metabolic diseases. In recent years, with the development of science and technology, hypoglycemic treatment has been gradually promoted, safer and more efficient hypoglycemic drugs have been emerging, including sulfonylureas, biguanides, glinides, α-glucosidase inhibitors, dipeptidyl peptidase Ⅳ inhibitors, glucagon like peptide-1 receptor agonists, sodium glucose cotransporter 2 inhibitors and various types of insulin preparations. A large number of studies have proved that intestinal flora may be one of the targets for hypoglycemic drugs to control blood glucose. In this article, we aim to review the effects of hypoglycemic drugs on the composition of intestinal flora and the regulation of nutrition and energy metabolism, and provide reference for future researches on mechanism and target of new antidiabetic drugs.

Objective To explore the long-term outcome of postpartum glucose metabolism among patients with gestational hyperglycemia and its risk factors.Methods Patients with gestational hyperglycemia,diagnosed by 100 g oral glucose tolerance test (OGTT) during 24th to 28th gestation week between 2010 and 2012 and giving the childbirth in Peking Union Medical College Hospital,were included.The glucose metabolism outcomes were evaluated by 75 g OGTT.The risk factors influencing the glucose metabolism outcome and the glucose metabolism parameter changes between the pregnancy term and now were also analyzed.Results Forty patients with gestational hyperglycemia were included.The follow-up time was postpartum 5-8 years and (6.83±0.74) years on average.Among them,3 patients were diagnosed with type 2 diabetes and 9 patients were diagnosed with impaired glucose intolerance.The overall rate of abnormal glucose metabolism was 30 percent.The third-hour glucose of OGTT larger than 7.45 mmol/L and the area under the glucose curve (Glu AUC) during OGTT larger than 24.875 mmol×h/L were the risk factors for the abnormal glucose metabolism outcome,with the odds ratio of 5.769 (95％ confidence interval 1.064-31.270,P=0.042) and 12.5 (95％ confidence interval 2.226-70.187,P=0.004).Using the 2-hour glucose larger than 8.25 mmol/L and 3-hour glucose larger than 7.45 mmol/L in the OGTT of midtrimester to judge the glucose state in the follow-up visit can achieve the diagnostic efficacy with the sensitivity of 75％,specificity of 82％,positive prediction value of 64％ and negative prediction value of 88％.Comparing with now,the fasting glucose in the midtrimester was lower ([5.49±0.43] vs.[4.55±0.47] mmol/L,P＜0.001),the fasting insulin in the midtrimester was high-er (12.30 [6.35,16.55] vs.8.31 [6.79,12.00] μIU/ml,P=0.048),HOMA-β in the midtrimester was higher (202.67 [145.71,335.71] vs.85.41 [78.63,112.13],P＜0.001).Conclusion The third-hour glucose larger than 7.45 mmol/L and the glucose area under the curve larger than 24.88 mmol×h/L in the OGTT of midtrimester are the risk factors for the abnormal glucose state in the postpartum long-term follow-up.The combination of the second-hour and the third-hour glucoses in the 100 g OGTT of midtrimester can help to predict the postpartum long-term glucose state.
