Objective To understand cognition level and treatment intention of patients with endometriosis(EMs);To evaluate the effects of TCM chronic disease management on EMs patients.Methods The disease cognition level and treatment intention of 1 895 EMs patients from October 2020 to December 2021 in 19 provinces,autonomous regions and municipalities were analyzed through cross-sectional investigation.The cognitive effect of chronic disease management of TCM on 801 patients with EMs from 6 Grade A hospitals in Beijing was evaluated by self-control study.Results The cognition level of EMs patients for the disease was improved with the increase of educational background.Patients generally believed that EMs was a chronic disease,requiring regular review and long-term management.The proportion of patients with high school education or below,junior college education,bachelor degree or above who knew the possibility of malignant changes in EMs was less,only 32.3%,41.6%and 47.7%,respectively.The awareness rate of patients with high school education or below for recurrence after EMs conservative surgery was 46.9%,lower than that of those with junior college education(66.8%)and bachelor degree or above(72.7%).Among the patients with dietary contraindications,the proportion of patients with high school education or below,junior college education,bachelor degree or above who knew the contraindication of the forest frog oil was less,only 20.7%,30.3%and 32.9%,respectively.In the aspect of life adjustment,the awareness of patients was generally high.EMs patients mainly recognized the disease through face-to-face communication with gynecologists.Only 34.4%of patients with high school education or below learned about EMs through WeChat public accounts,APPs and other new media,which was lower than those with junior college education(48.6%)and bachelor degree or above(55.4%).EMs patients generally tend to be treated in comprehensive hospitals,with high acceptance of TCM treatment,mainly TCM decoction,and low acceptance of TCM appropriate technology.After 1 year of TCM chronic disease management,the disease awareness of EMs patients was significantly improved compared with before management,with statistical significance(P<0.05).Conclusion EMs patients with different educational backgrounds have different cognition of the disease,and each has different emphasis.Education and popularization should be carried out according to their knowledge blind spots.Chronic disease management of TCM can improve the disease cognition level of EMs patients.

Delayed gastric emptying (DGE) is a common complication after pancreaticoduodenectomy (PD). The etiology and pathogenesis of DGE have not been fully elucidated in China and globally, and the majority of patients can be cured after general symptomatic treatment. This article reviews the risk factors and pathophysiological mechanisms of DGE after PD, in order to provide a reference for the effective management of DGE after PD in clinical practice.

OBJECTIVE: To investigate the role of hippocampal neurodevelopment in the antidepressant effect of baicalin. METHODS: Forty male Institute of Cancer Research mice were divided into control, corticosterone (CORT, 40 mg/kg), CORT+baicalin-L (25 mg/kg), CORT+baicalin-H (50 mg/kg), and CORT+fluoxetine (10 mg/kg) groups according to a random number table. An animal model of depression was established by chronic CORT exposure. Behavioral tests were used to assess the reliability of depression model and the antidepressant effect of baicalin. In addition, Nissl staining and immunofluorescence were used to evaluate the effect of baicalin on hippocampal neurodevelopment in mice. The protein and mRNA expression levels of neurodevelopment-related factors were detected by Western blot analysis and real-time polymerase chain reaction, respectively. RESULTS: Baicalin significantly ameliorated the depressive-like behavior of mice resulting from CORT exposure and promoted the development of dentate gyrus in hippocampus, thereby reversing the depressive-like pathological changes in hippocampal neurons caused by CORT neurotoxicity. Moreover, baicalin significantly decreased the protein and mRNA expression levels of glycogen synthase kinase 3β (GSK3β), and upregulated the expression levels of cell cycle protein D1, p-mammalian target of rapamycin (mTOR), doublecortin, and brain-derived neurotrophic factor (all P<0.01). There were no significant differences between baicalin and fluoxetine groups (P>0.05). CONCLUSION Baicalin can promote the development of hippocampal neurons via mTOR/GSK3β signaling pathway, thus protect mice against CORT-induced neurotoxicity and play an antidepressant role.

ObjectiveTo investigate the dynamic change of monocyte-derived macrophages （MDMs） in chronic hepatitis B （CHB） during the treatment by ETV or TDF， and the association between the polarization of monocyte-derived macrophages （MDMs） and HBV DNA， HBeAg in CHB. MethodsPeripheral blood of 101 patients with chronic hepatitis B and 20 healthy donors were enrolled. MDMs were purified from 86 patients with CHB and 12 healthy donors by peripheral blood mononuclear cell （PBMC）. Flow cytometry was use to analyze the expression of specific markers on polarized macrophages to further evaluate the polarization of MDMs （M1/M2 MDMs）， including CD80， HLA-DR， CD163 and CD206. Additionally， qPCR was used to evaluate the mRNA expression of inflammatory factors of MDMs in 15 patients with chronic hepatitis B and 8 healthy controls. ResultsThe proportion of CD163⁺CD206⁺MDMs （M2 MDMs） were reduced in patients with CHB （P = 0.030）， compared with healthy controls. Correspondingly， the mRNA expression of anti-inflammatory factor， IL-10， decreased significantly （P = 0.040）. With the progress of nucleos（t）ide analogs （NAs） therapy， the proportion of CD163⁺CD206⁺MDMs （M2 MDMs） increased gradually （P < 0.001）， while the proportion of CD80⁺HLA-DR⁺MDMs （M1 MDMs） decreased gradually （P = 0.005）. In addition， M2 MDMs were negatively associated with both HBeAg （P = 0.019）， HBV DNA （P = 0.002）， AST （P = 0.048） and ALT （P = 0.030） in patients with CHB. ROC curve analysis showed that CD163⁺CD206⁺MDMs （M2 MDMs） had high predicting value for the virologic response of CHB during NA therapy， and could be used to predict undetectable HBV DNA ［ROC 95％CI： 0.705 （0.594，0.815）］ and HBeAg seroconversion ［ROC 95％CI： 0.740 （0.634，0.847）］. ConclusionsThere are dynamic changes of MDMs polarization in patients with CHB during NA therapy， and the negative correlation between the proportion of M2 MDMs and HBV DNA， HBeAg indicates that M2 MDMs could have a high predicting value in the virologic response of CHB during NA therapy.

Objective:To analyse the clinical features of encephalitis patients with antibodies against the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR).Methods:Three anti-AMPAR encephalitis patients diagnosed in Tangdu Hospital, the Air Force Military Medical University between January 2020 and May 2021 were retrospectively reviewed. The clinical symptoms, supplementary examination, treatment options and outcomes with knowledge from literature were summarized in this study.Results:Three patients aging from 12 to 70 years presented with symptoms ranging from cognitive impairment, personality change to headache and paralysis. The lung occupying lesion was pathologically proved to be small cell lung cancer in case 1. Antibody to AMPAR (AMPAR-ab) was positive in both blood and cerebrospinal fluid of case 1, with coexisting antibodies against sex-determining region of Y chromosome-related high mobility group box 1 in blood, and the symptoms persisted but did not recur following therapy with corticosteroids. AMPAR-ab was detected only in serum in case 2, with the lesion located in both frontal and temporal lobes, centrum semiovale and lateral ventricle, combined with classic imaging features of intracranial hypotension, and the syndrome was partially improved following treatment with corticosteroids. The lesions were located in the pons and middle cerebellar peduncle, accompanied by cerebellar atrophy in case 3. Spinal cord magnetic resonance imaging showed long hyperintense lesions involving the cervical and thoracic cord, extending from C 2 to Th 10 level on T 2-weighted images. AMPAR-ab was positive in both serum and cerebrospinal fluid. And the symptoms improved significantly following treatment with corticosteroids and intravenous immunoglobulin. Conclusions:The clinical manifestations of anti-AMPAR encephalitis are highly heterogeneous, and brainstem and spinal cord can also be involved in addition to the limbic system, accompanied by brain atrophy. Combining with concurrent antibodies, especially the intracellular antibodies, malignancy needs to be closely monitored; the immunotherapy is effective and the presence of tumor superimposed with multiple antibodies may be associated with poor prognosis.

Objective:To demonstrate the clinical effect of latissimus dorsi musculocutaneous flap with primary closure in V-Y suture in the repair of major lesions in the anterior chest wall that was left after mastectomies with locally advanced breast cancer (LABC) surgery.Methods:From September 2018 to February 2021, the technique was employed on 14 female cancer patients who had LABC surgery in the Department of Breast Surgery of the First Affiliated Hospital of Kunming Medical University. The patients received radical mastectomies with major resection of cutaneous tegument. The defect areas in chest wall were 15.0 cm×15.0 cm-22.0 cm×35.0 cm. The sizes of flap were 12.0 cm×28.0 cm-18.0 cm×35.0 cm. The sizes of musculocutaneous flap were 12.0 cm×28.0 cm×2.0 cm~18.0 cm×35.0 cm×3.5 cm. All patients were entered the postoperative follow-up through out-patient clinic and telephone interviews.Results:The flap provided an efficient coverage in closing the defects among all 14 patients. Three patients presented small areas (1.0-3.0 cm) of superficial necrosis in Y-cross area of the flap. None of the patient had back swelling. The average operation time was 6.3 hours. Postoperative follow-up varied from 4 to 41 months(18 months in average). The colour, texture, elasticity of the flaps were acceptable, with good shapes. Function of upper limbs was normal in 13 cases without lymphedema, except 1 who had lymphedema of affected limb at 3 years after surgery. Eleven cases had radiotherapy after surgery with good tolerance. None of the cases had local recurrence of breast cancer. Five cases had metastasis, 3 cases died of metastasis.Conclusion:The latissimus dorsi musculocutaneous flap with primary closure in V-Y suture is easy to perform and an reliable and efficient technique in repairing large defects in the anterior chest wall left after a LABC surgery.

This study is to provide the basis of establishing a quality evaluation system, based on the differences in appearance and internal components of Astragali Radix from different sources. The diameter of 18 batches of Astragali Radix, the content of alcohol(water) extract and 7 kinds of flavonoids were determined. The peak area ratio of flavonoid aglycon to aglycone was calculated. PCA and CA were carried out by synthesizing various indexes. The results of PCA and CA showed that Astragali Radix was obviously clustered into three types. Alcohol extract, formononetin/formosan glycosides,(pilose isoflavones+astragalus flavonoid A)/pilose isoflavone glucoside are the most significant differences in the variable importance projection index(VIP) of Astragali Radix. Combining the diameter, alcohol(water) extract, flavonoid aglycon to aglycone peak area ratio can provide an analysis method for the establishment of the grade evaluation system of Astragali Radix.

Objective:To observe the clinical efficacy of the modified Buzhong Yiqitang combined with Erxian decoction in treating stress urinary incontinence （SUI） of perimenopausal women due to spleen and kidney Qi deficiency. Method:One hundred and six patients were randomly divided into a control group （52 cases） and an observation group（54 cases）. Patients in both groups received lifestyle intervention and pelvic floor muscle training （PFMT）. On this basis， patients in the observation group were further treated with the modified Buzhong Yiqitang combined with Erxian decoction， 1 bag/day， while those in the control group were provided with Suoquan pills， 6 g/time， 2 times/day， for eight weeks. Following the international consultation on incontinence questionnaire-short form （ICIQ-SF） scoring before and after treatment， the urodynamic parameters such as maximum urinary flow rate （Q_max）， maximum urethral closure pressure （MUCP）， residual urine volume （RUV）， abdominal pressure leakage point pressure （ALPP）， and bladder capacity （BC） were measured. The number of incontinence episodes per 24 h， the degree of urinary incontinence， the amount of 1 h urine leakage， and the spleen and kidney Qi deficiency syndrome score were recorded before and after treatment. The levels of estradiol （E₂）， follicle stimulating hormone （FSH）， pituitary adenylate cyclase activating peptide （PACAP）， and vasoactive intestinal peptide （VIP） were measured before and after treatment. Result:The ICIQ-SF sub-scores of the urinary incontinence frequency， severity， and impact on quality of life as well as the total score in the observation group were all lower than those in the control group （P<0.01）. Q_max， MUCP， ALPP and BC in the observation group were elevated in contrast to those in control group （P<0.01）， while the RUV declined （P<0.01）. Compared with the control group， the observation group exhibited a decreased number of incontinence episodes per 24 h， milder degree of urinary incontinence， reduced amount of 1 h urine leakage， and lower spleen and kidney Qi deficiency syndrome score （P<0.01）. The E₂， PACAP， and VIP in the observation group were up-regulated as compared with those in the control group （P<0.01）， whereas the FSH was down-regulated （P<0.01）. The cure and effective rates of the observation group were （29/50） 58.00% and （47/50）94.00%， respectively， significantly better than （18/48）37.50% and （38/48）79.17% of the control group （χ²=4.124， χ²=4.683， P<0.05）. Conclusion:On the basis of the lifestyle intervention and PFMT， the modified Buzhong Yiqitang combined with Erxian decoction obviously alleviates urinary incontinence， adjusts sex hormones， PACAP and VIP， ameliorates urodynamic parameters， and enhances the quality of life of patients with SUI due to spleen and kidney Qi deficiency. The resulting cure and effective rates are superior to those of the positive control.

Objective: To investigate the relationship between after-school schedule and bone mineral density in middle-school students in Shanghai, to provide a reference for taking targeted measures. Methods: From November 2017 to April 2018，eighteen classes of six middle schools in Shanghai (from urban districts, urban-suburb combined districts and suburban districts, respectively) were selected based on cluster random sampling. In each school, 2-4 classes were further randomly chosen in the 6th grade. Questionnaires were completed by 518 students and their parents, as well as physical examination and bone mineral density assessment. Results: The average time spent on after-school academic learning during weekends was 4.0 (IQR: 2.0, 6.0) h. The Z-score of bone density was 0.3 (IQR: -0.7, 1.0). The smooth curve fit model showed a non-linear relationship between after-school academic learning time during weekends and the Z-scores of bone mineral densities. A two-stage multiple linear regression analysis was further applied according to the fit results, and the results showed that when total afterschool academic learning time <4.5 hours during weekends, the learning time was inversely correlated with the bone density Z-scores (β=-0.11,P=0.01), and when the learning time ≥4.5 hours, there was no significant correlation between the learning time and bone density Z-scores (β=0.02, P=0.65). Parent and student questionnaires showed that there was a non-linear relationship between students’ daily time spent on outdoor sports-related activities and bone density Z-scores. When time spent on the outdoor activities ≥45 minutes per day, outdoor activities were positively correlated with bone density Z-scores (P<0.05). However, when the time spent on outdoor activities <45 minutes per day, there was no significant relationship between outdoor activities and bone density Z-scores (P>0.05). Conclusion Too much time on after-school academic learning during weekends or limited time on outdoor activities are both related to impaired bone mineral densities. Therefore, a reasonable after-school schedule for middle-school students is important for physical development, especially during weekends.

BACKGROUNDIncreased proinflammatory cytokines and chemokines might contribute to infiltration of inflammatory cells and remodeling in airways of asthma. Although these molecules may be associated with asthma, there is lack of systemic evidence showing which and how important these events are in the disease. We aimed to analyze the concentrations of these molecules in the airways and relationships with disease severity and with airway infiltration of inflammatory cells in a large cohort of asthmatics (n = 70, including 37 mild and 33 moderate/severe asthmatics) compared with controls (n = 30).

METHODSMeso scale discovery system and commercial ELISA kits were used to measure the concentrations of proinflammatory cytokines interleukin (IL)-1β; tumor necrosis factor-alpha (TNF-α); IL-6; and IL-17 and CC and CXC chemokines CCL2, CCL4, CCL11, CCL13, CCL17, CCL22, and CCL26 and CXCL8, CXCL9, CXCL10, and CXCL11 in bronchoalveolar lavage fluid of asthmatics and controls.

RESULTSThe concentrations of IL-1, TNF-α, IL-6, CXCL8 and CXCL10, and CCL4, CCL11, CCL17, and CCL22 were significantly elevated in asthmatics compared with controls (P < 0.05). The concentrations of TNF-α and CXCL8, but not others, were negatively correlated with severity of disease (lung function forced expiratory volume in 1 s) (TNF-α vs. total: r = -0.359, P= 0.002 vs. moderate/severe: r= -0.541, P= 0.001; CXCL8 vs. total: r = -0.327, P= 0.006 vs. moderate/severe: r = -0.625, P= 0.0001, respectively). In addition, concentrations of these two molecules were also correlated with the absolute numbers of infiltrating eosinophils and neutrophils in asthmatic airways.

CONCLUSIONSIncreased concentrations of TNF-α and CXCL8 are associated with pathogenesis of asthma. Targeting these molecules might provide an alternative therapeutic for this disease.
