ABSTRACT
Objective:To explore the clinical effect and safety of intrinsic-nourishing exercise and oral Chinese medicine combined with conventional western medicine therapy in the treatment of perimenopause with insomnia.Methods:Prospective cohort study. A total of 60 perimenopause with insomnia visiting the Hebei Medical Qigong Hospital were enrolled as the research objects between June 2019 and June 2021. According to random number table method, they were divided into the control group and the observation group, 30 in each group. The control group was treated with oral estazolam tablets, while the observation group was treated with intrinsic-nourishing exercise combined with oral Chinese medicine on basis of the control group. All the patients were treated for 4 weeks as a course, and totally 2 courses. The levels of serum estradiol (E 2), FSH, and LH were detected by automatic chemiluminescence immunoassay analyzer. Pittsburgh sleep quality Index (PSQI) was used to evaluate sleep quality, and the quality of life was evaluated by the MOS 36-item Short Form Health Survey (SF-36). And the responsive rates, sleep quality, scores of TCM symptoms, and adverse reactions were compared before and after treatment. Results:The total response rate of observation group was significantly higher than that of the control group (90.0% vs. 66.7%; χ2=4.81, P<0.05). After treatment, PSQI scores of sleep quality, time to fall asleep, sleep duration, sleep efficiency, sleep disturbance, use of hypnotics, and daytime function in the observation group were significantly lower than those in the control group ( t=14.11, 12.49, 9.88, 13.54, 9.47, 14.11, 17.91, P<0.01). After treatment, the TCM symptom scores of insomnia with more dreams, waist and knee soreness, five upsets, fatigue and forgetfulness in the observation group were significantly lower than those in the control group ( t=9.51, 13.08, 16.17, 12.81, P<0.01). After treatment, the E 2 [(35.16±3.61) mmol/L vs. (31.06±3.12) mmol/L, t=4.71] in the observation group was significantly higher than that of the control group ( P<0.01), while the FSH [(69.61±6.04) U/L vs. (73.26±7.41) U/L, t=2.09], and LH [(32.21±3.35) U/L vs. (36.04±3.49) U/L, t=4.34] in the observation group were significantly lower than those in the control group ( P<0.05 or P<0.01). At 4 and 8 week after treatment, the SF-36 scores in the observation group were significantly higher than those in the control group ( t=6.30, 4.36, P<0.01). During treatment, 16.7% (5/30) adverse reaction happened in the observation group, while 10.0% (3/30) in the control group, but there was no statistical significant difference between two groups ( χ2=0.56， P=0.448). Conclusion:The intrinsic-nourishing exercise and oral Chinese medicine combined with conventional western medicine therapy can significantly improve clinical curative effect, improve sleep quality and TCM symptoms, regulate hormones and quality of life in perimenopause with insomnia.

ABSTRACT
【Objective】 To explore the technical methods and clinical efficacy of transvaginal or transrectal repair in the treatment of iatrogenic bladder fistula. 【Methods】 The clinical data of 7 cases of iatrogenic bladder fistula patients treated during 2016 and 2019 were retrospectively analyzed, including 6 cases of vesicovaginal fistula (VVF) and 1 case of vesicorectal fistula (VRF). The operation was conducted 3 to 10 months after the diagnosis of urinary fistula, and the vagina or rectum was fully cleaned before operation. Modified Latzko technique was employed to separate the gap between the bladder wall and vaginal or rectal wall along the fistula, the fistula scar was sharply removed, and the fistula, bladder wall, vaginal or intestinal wall, and vaginal or intestinal mucosa were sutured in layers. The urinary catheter was indwelled for 4 weeks. 【Results】 All 7 cases were successfully repaired at one procedure. No urine leakage was found after the urinary catheter was removed. There was no recurrence after 6 to 12 months of follow-up. 【Conclusion】 Selective application of the modified Latzko technique to repair iatrogenic urinary fistula through the natural lumen is an advantageous treatment scheme, which simplifies the operation and reduces trauma.
ABSTRACT
Purpose@#Invasive ductal carcinoma (IDC) accounts for 90% of triple-negative breast cancer (TNBC). IDC is mainly derived from the breast ductal epithelium which is innervated by the 4th to 6th thoracic sympathetic nerves. However, little is known about the contribution of the interactions between sympathetic nerves and breast cancer cells to the malignant progression of TNBC. @*Methods@#The expression levels of the β2 -adrenergic receptor (β2 -AR, encoded by ADRB2 gene), nerve growth factor (NGF), and tropomyosin receptor kinase A (TrkA) were determined using immunohistochemistry (IHC). NGF expression levels in the serum were compared by enzyme-linked immunosorbent assay (ELISA). Cell proliferation was assessed using the Cell Counting Kit-8 assay. The β2 -AR, NGF, p-ERK, and p-CERB expression levels were determined using western blotting. TNBC cells and neuronal cells of the dorsal root ganglion (DRG) in 2-day-old Sprague Dawley rats were co-cultured. Using norepinephrine (NE), NGF, and β2 -AR, NGF/TrkA blocker pretreatments, the axon growth of each group of DRG neuron cells was detected by immunofluorescence analysis. @*Results@#The sympathetic adrenergic neurotransmitter NE activated the ERK signaling pathway in TNBC cells. NE/β2 -AR signaling promotes NGF secretion. NGF further facilitates the malignant progression of TNBC by increasing sympathetic neurogenesis. In the coculture assay, the sympathetic adrenergic NE/β2 -AR signal pathway also enhanced NGF secretion. NGF binds TrkA in DRG neurons and promotes axonal growth. @*Conclusion@#These results suggest that NE/β2 -AR pathway promotes cell proliferation and NGF production in triple-negative breast cancer.

ABSTRACT
Gardeniae Fructus (GF) and Semen Sojae Praeparatum (SSP) are both medicine food homologies and widely used in Chinese clinical prescriptions together. The research investigated the pharmacokinetics of four iridoids in normal rats and isolfavones-fed rats, which were administered with isolfavones from SSP for 7, 14, 21 and 28 consecutive days. A validated LC-MS/MS method was developed for determining shanzhiside, genipin-1-gentiobioside, geniposide and their metabolite genipin in rat plasma. Plasma samples were pretreated by solid-phase extraction using paeoniflorin as the internal standard. The chromatographic separation was performed on a Waters Atlantis T3 (4.6 mm × 150 mm, 3μm) column using a gradient mobile phase consisting of acetonitril and water (containing 0.06％acetic acid). The mass detection was under the multiple reaction monitoring (MRM) mode via polarity switching between negative and positive ionization modes. The calibration curves exhibited good linearity (r>0.997) for all components. The lower limit of quantitation was in the range of 1-10 ng/mL. The intra-day and inter-day precisions (RSD) at three different levels were both less than 12.2％ and the accuracies (RE) ranged from -10.1％ to 16.4％. The extraction recovery of them ranged from 53.8％ to 99.7％. Pharmacokinetic results indicated the bioavailability of three iridoid glycosides and the metabolite, genipin in normal rats was higher than that in rats exposed to isoflavones. With the longer time of administration of iso-flavones, plasma concentrations of iridoids decreased, while genipin sulfate, the phase II metabolite of genposide and genipin-1-gentiobioside, appeared the rising exposure. The pharmacokinetic profiles of main iridoids from GF were altered by isoflavones.
ABSTRACT
Objective:To investigate the clinical characteristics and related risk factors of sarcopenia in elderly patients undergoing maintenance hemodialysis.Methods:This was a retrospectively study involving 135 elderly hemodialysis patients aged(70.6±7.7)years, with 46(34.1%)females and a mean hemodialysis duration of(3.2±2.9)years, at Shanghai Sixth People's Hospital.The incidence of sarcopenia in patients was examined by measuring handgrip strength, walking speed and muscle mass of the limbs using bioelectrical impedance analysis.Related risk factors were analyzed with univariate and multivariate logistic regression analysis.Results:Among 135 elderly hemodialysis patients, the incidence of sarcopenia was 62.9%(85 cases), and severe sarcopenia cases accounted for 44.4%(60 cases). Compared with the non-sarcopenia group, patients with sarcopenia were older, had lower body mass index(BMI)and handgrip strength, walked more slowly and had less muscle mass in their limbs.Advanced age, low BMI and long dialysis duration were correlated with the high incidence of sarcopenia in elderly dialysis patients.The odds ratio( OR)for sarcopenia increased by 12% per year, and the OR decreased by 32% with an increase of 1.0 kg/m 2 in BMI.Advanced age and lower BMI were also correlated with a high incidence of severe sarcopenia( OR=1.12, 95% CI: 1.05~1.18; OR=0.84, 95% CI: 0.74~0.95; all P<0.01). Conclusions:The incidence of sarcopenia is high in elderly hemodialysis patients and is closely related to advanced age and low body weight.Improving nutritional status and avoiding low body weight will help reduce the occurrence and development of sarcopenia in elderly hemodialysis patients.

ABSTRACT
OBJECTIVE： To screen and characterize effective components of immunopotentiating activity in Senecionis cannabifolii Herba. METHODS： The polysaccharide components were obtained by water extraction and alcohol precipitation method to yield 50％ alcohol precipitation sample （SCHE-1） and 80％ alcohol precipitation sample （SCHE-2）. The cells from mice mononuclear macrophage line RAW264.7 were divided into blank group （medium without serum）， negative control group （medium with serum）， lipopolysaccharide group （LPS， positive control drug， 1 μg/mL）， SCHE-1 and SCHE-2 low-dose and high-dose groups （0.5， 1 mg/mL）. The cell viability of RAW264.7 cells was detected by MTT assay. The levels of IL-1β， IL-6 and TNF-α in RAW264.7 were detected by ELISA. These were used to investigate the effects of SCHE-1 and SCHE-2 on the immunological enhancing activity of RAW264.7 cells. The molecular weight and distribution of SCHE-1 were determined by size exclusion chromatography； the monosaccharide composition of SCHE-1 was determined by HPLC pre-column derivatization. Methylation analysis of SCHE-1 was conducted by NaOH method. RESULTS： Compared with negative control group， the activity of RAW264.7 cells was enhanced significantly in SCHE-1 groups and LPS group， which also significantly increased the levels of IL-1β， IL-6 and TNF-α in cell culture fluids （P＜0.01）. SCHE-1 was an effective component with immunopotentiating activity. The neutral sugar content of SCHE-1 was 40.05％， the uronic acid was 35.62％， and the protein was 8.89％. SCHE-1 was a mixture， molecular weight of which was 62-6 119 Da； monosaccharide was mainly composed of galacturonic acid， arabinose （Ara） and galactose （Gal）. The results of methylation analysis showed that the backbone was composed of 1→3， 1→4 and 1→6 linked Gal， and branches were on the O-6 position of the 1→3 linked Gal， and the non-reducing terminals were Ara. CONCLUSIONS： SCHE-1 may be the effective component of immuno potentiating activity， and main component of SCHE-1 is polysaccharide. SCHE-1 may regulate the immune function by activating macrophages to release IL-1β， IL-6 and TNF-α.

ABSTRACT
Depression is a serious health hazard and the World Health Organization predicts that depression will be the second leading cause of abnormal death and disability by 2020.Currently,most antidepressants are tricyclic antidepressants (TCA),tetracyclic antidepressants and selective 5- HT reuptake inhibitors.Long term use of those medications will develop resistance and adverse reactions.In addition,drugs that block a single target are often hard to achieve therapeutic outcomes due to the biological abnormalities involving multiple systems in the body.Traditional Chinese Medicine(TCM)can simultaneously act on multiple targets to influence the disease network in many aspects at the same time.This approach has higher efficacy and lower side effects than a single chemical medication.Recently,there are increasing numbers of research papers on antidepres-sant mechanism of TMC,mainly focused on the release level of neurotransmitters,hippocampus brain derived neurotrophic fac-tor(BDNF)expression and cytokines,etc.The latest researches also indicated that the gut microbiota has involved the devel-opment of emotional diseases and the diseases related to central nerves system.This paper reviews the mechanism studies of TMC as antidepressants and neuroprotection agents in order to shed new light on the study of depression pathogenesis and de-velopment of new antidepressant medications.

Staphylococcus aureus(S.aureus) secretes a variety of pathogenic toxins and one of the most prominent toxins is α-hemolysin,which is considered as the main virulence factor in skin necrosis and severe infections caused by S.aureus infection. α-hemolysin is so named because of its ability to dissolve red blood cells. However,it has a wide range of effects on various cells and may cause different pathogenic re-sponses in different host cells. This review summarizes recent studies on the structure of α-hemolysin and its interaction with different cells in order to better understand the role of α-hemolysin in the process of S.aureus infection,which may provide a reference for developing new approaches to the prophylaxis and treatment of S.aureus infection.
ABSTRACT
Objective To investigate the continuous ambulatory peritoneal dialysis (CAPD) and daytime ambulatory peritoneal dialysis (DAPD) on sleep and quality of life. Methods In this is a multi-center cross-sectional survey, we used the Pittsburgh Sleep Index Scale (PSQI) and the Chinese version of peritoneal dialysis patient quality of life scale, the unified investigating time, the organized trained peritoneal dialysis nurses qualified to conduct research full-time. Survey content includes general information, sleep and quality of life, laboratory tests, dialysis adequacy and other indicators, and the results were pooled analysis. Results A total of 325 hospitalized peritoneal dialysis patients were included in the study, including 177 patients in CAPD, 148 patients in DAPD. The total scores of QOL, physical function, physical factors, psychological status, social function and life satisfaction were (72.61± 10.94), (19.44±3.65), (59.69±7.31), (32.65±5.65), (24.82±6.03), (15.42±5.47)and (74.06±13.59), (20.16± 2.95), (58.99 ± 5.86), (34.58 ± 6.17), (25.10 ± 5.01), (15.36 ± 4.28). The score of CAPD in the mental state dimension was significantly lower than that in DAPD patients (t=-3.715, P 0.05). Conclusions Sleep and quality of life in peritoneal dialysis patients are lower than normal adults. Dialysis modes have an impact on sleep andquality of life of patients, health care workers should fully assess the physical and mental state of the patients in order to select the appropriate mode of dialysis.
