Objective To investigate the efficacy of Bushen Tiaojing Decoction,a prescription derived from Daying Decoction which recorded in Jing Yue Quan Shu(The Complete Works of ZHANG Jing-Yue)and with herbs added,combined with human recombinant interferon-α-2b for the treatment of endometriosis(EMs)and to observe its effects on humoral immunity,serum carbohydrate antigen 125(CA125)and anti-endometrial antibody(EMAb)levels of EMs patients.Methods A total of 86 cases of EMs patients with kidney deficiency and blood stasis syndrome were randomly divided into observation group and control group,with 43 cases in each group.The control group was treated with human recombinant interferon-α-2b alone,and the observation group was treated with Bushen Tiaojing Decoction combined with human recombinant interferon-α-2b.The course of treatment covered one month.The changes of humoral immune factors of immunoglobulin A(IgA),complement 3(C3)and complement 4(C4),endometrial ectopic mass diameter,and the levels of pathology-relevant factors of CA1 25 and EMAb in the two groups before and after treatment were observed.Moreover,the clinical efficacy and safety of the two groups were evaluated.Results(1)After one month of treatment,the total effective rate of the observation group was 97.67％(42/43),and that of the control group was 81.40％(35/43).The intergroup comparison(tested by chi-square test)showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the serum IgA level of the two groups was significantly higher than that before treatment(P＜0.05),and the serum C3 and C4 levels were significantly lower than those before treatment(P＜0.05).The increase of serum IgA level and the decrease of serum C3 and C4 levels in the observation group were significantly superior to those in the control group(P＜0.01).(3)After treatment,the serum CA125 and EMAb levels and the diameter of endometrial ectopic mass in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease of serum CA125 and EMAb levels and the diameter of endometriosis mass in the observation group was significantly superior to that in the control group(P＜0.01).(4)The total incidence of adverse reactions in the observation group was 6.98％(3/43)and that in the control group was 11.63％(5/43),and the difference between the two groups was not significant(P＞0.05).Conclusion Bushen Tiaojing Decoction combined with human recombinant interferon-α-2b has a significant clinical effect for the treatment of EMs patients with kidney deficiency and blood stasis syndrome.The combined therapy is effective on improving the levels of humoral immune factors,serum CA125 and EMAb,and reducing endometrial ectopic mass,with high safety.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Objective:To analyze the source of infection， clinical symptoms and epidemiological characteristics of pertussis surveillance cases in Minhang District of Shanghai from 2017 to 2019，so as to provide the basis for pertussis surveillance and immunization strategy. Methods:Descriptive epidemiological method was used to analyze the pertussis surveillance cases. Results:A total of 334 cases were included in the pertussis active surveillance system， 237 cases were confirmed cases. There were 13 towns or streets in Minhang District， except for Pujin Street， all the other 12 towns or streets had cases. The high risk group （131/237， 55.27% of the cases） were the infants under five months old who did not reach the age of immunization or did not complete the basic immunization of diphtheria， tetanus， and acellular pertussis combined vaccine （DTaP）. The cases mainly occurred in March to July， accounting for 71.31% （169/237）. The highest culture-positive rate of Bordetella pertussis was in August （82.76%， 24/29）； the highest positive rate of polymerase chain reaction （PCR） detection was in March （58.82%， 20/34）. All the monitored cases had cough symptoms with an average cough days of 22.05±9.81 in confirmed cases. A total of 64 clustered outbreaks were detected， with an attack rate of 37.45% （94/251）. 32.91% （78/237） of the cases had contact history with coughing patients 21 days before the onset， and 94.87% （74/78） of them were family members. The aggregation of pertussis was mainly transmitted from adults to infants and infants to adults. Conclusion:Children under five months old are the high incidence population of pertussis， and family members are the main source of infection. It is suggested that pertussis monitoring and prevention should be carried out in adolescents and adults.

We investigated the potential hepatoprotective effect of Radix Bupleuri (RB) by inducing acute liver injury (ALI) in an animal model using acetaminophen (APAP) after pretreatment with RB aqueous extract for three consecutive days. Compared to those of the APAP group, the biochemical and histological results of the RB pretreatment group showed lower serumaspartate transaminase (AST) and alanine transaminase (ALT) levels as well as less liver damage. Pharmacokinetic study of the toxicity related marker acetaminophen-cysteine (APC) revealed a lower exposure level in rats, suggesting that RB alleviated APAP-induced liver damage by preventing glutathione (GSH) depletion. The results of cocktail approach showed significant inhibition of CYP2E1 and CYP3A activity. Further investigation revealed the increasing of CYP2E1 and CYP3A protein was significantly inhibited in pretreatment group, while no obvious effect on gene expression was found. Therefore, this study clearly demonstrates that RB exhibited significant protective action against APAP-induced acute live injury via pretreatment, and which is partly through inhibiting the increase of activity and translation of cytochrome P450 enzymes, rather than gene transcription.

Objective: To investigate the effect of Liuwei Dihuangwan on connexin 32 (Cx32) in hepatoma cell line CBRH7919 and its gap junction intercellular communication (GJIC), and furthermore study its mechanism of enhancing the bystander killing effect of suicide gene therapy. Method: Liuwei Dihuangwan (32 g·kg·d^-1) and the same volume of normal saline were given to the rats by intragastrical administration. Blood was taken to prepare the medicated serum of Liuwei Dihuangwan and blank control serum, respectively. The hepatoma cell line CBRH7919 were treated by control serum and medicated serum of Liuwei Dihuangwan in different concentrations. There were four groups in experiment:the blank control group (volume fraction of 10%), medicated serum high dose group of Liuwei Dihuangwan (the volume fraction of 10%), medicated serum middle dose group of Liuwei Dihuangwan (the volume fraction of 5%), and medicated serum low dose group of Liuwei Dihuangwan (the volume fraction of 2.5%). The expression levels of Cx32 protein and mRNA in hepatoma cell line CBRH7919 were detected by indirect immunofluorescence assay (ⅡA) and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) assay. The fluorescence redistribution after photobleaching (FRAP) method was used to detect the function of GJIC of hepatoma cell line CBRH7919. Result: ① The indirect immunofluorescence assay (ⅡA) analysis indicated that as compared with the blank control group, the cx32 expression of CBRH7919 cells was up-regulated in a concentration-dependent manner in each dose group of the serum containing Liuwei Dihuangwan (P<0.05 in low dosage group; P<0.01 in middle dosage and high dosage group), especially on cell membrane.② The results of Real-time PCR assay indicated that as compared with the blank control group, the expression of Cx32 mRNA was increased in each dose group (P<0.05 in low dose group, P<0.01 in middle and high dose group) in a dose-effect relationship. ③ The result of fluorescence redistribution after photobleaching (FRAP) analysis indicated that the average fluorescence recovery rates of drug groups were significantly higher than that in blank control group, and also showed a certain concentration-dependent trend. Conclusion: The mechanism of medicated serum of Liuwei Dihuangwan in enhancing the bystander killing effect of suicide geneis related to gap junction. Liuwei Dihuangwan may enhance the function of GJIC by increasing the localization of cx32 on the cell membrane of CBRH7919 cells and increasing the expression of cx32 mRNA and protein to achieve the synergistic action.

Background: With the publication of Sepsis-3 definition, epidemiological data based on Sepsis-3 definition from middle-income countries including China are scarce, which prohibits understanding of the disease burden of this newly defined syndrome in these settings. The purpose of this study was to describe incidence and outcome of Sepsis-3 in Yuetan sub-district of Beijing and to estimate the incidence rate of Sepsis-3 in China. Methods: The medical records of all adult residents hospitalized from July 1, 2012 to June 30, 2014 in Yuetan sub-district of Beijing were reviewed. Patients with sepsis-3 and severe sepsis/septic shock were identified. The incidence rates and mortality rate of sepsis-3 and sepsis/septic shock were calculated, incidence rates and in-hospital mortality rates were normalized to the population distribution in the 2010 National Census. Population incidence rate and case fatality rate between sexes were compared with the Z test, as the data conformed to Poisson distribution. Results: Of the 21,191 hospitalized patients, 935 patients were diagnosed with Sepsis-3, and 498 cases met severe sepsis/septic shock criteria. The crude annual incidence rate of Sepsis-3 in Yuetan sub-district was 363 cases per 100,000 population, corresponding to standardized incidence rates of 236 cases per 100,000 population per year, respectively. The overall case fatality rate of Sepsis-3 was 32.0%, the crude population mortality rates of Sepsis-3 was 116 cases per 100,000 population per year, the standardized mortality rate was 67 cases per 100,000 population per year, corresponding to a speculative extrapolation of 700,437 deaths in China. The incidence rate and mortality rate of Sepsis-3 were significantly higher in males, elderly people, and patients with more comorbidities. The 62.1% of patients with Sepsis-3 had community-acquired infections, compared with 75.3% of infected patients without Sepsis-3 (P < 0.001). The most common infection in patients with Sepsis-3 was lower respiratory tract infection. When compared with patients with Sepsis-3, patients diagnosed as severe sepsis/septic shock were more likely to have higher case fatality rate (53.4% vs. 32.0%, P < 0.001) Conclusions: This study found the standardized incidence rate of 236 cases per 100,000 person-year for Sepsis-3, which was more common in males and elderly population. This corresponded to about 2.5 million new cases of Sepsis-3 per year, resulting in more than 700,000 deaths in China.

PURPOSETo investigate effects of neuro-immuno-modulation on wound healing by observing changes of cytokines and hypothalamic-pituitary-adrenal (HPA) axis hormones in acute stress reaction in rats with wound and combined local radiation injury.

METHODSSixty female Wistar rats (weighting 200 ± 20 g) were randomly divided into normal control group, wound group and combined wound-local radiation (CWR) group (25 Gy local radiation post wound), 20 rats in each group. Contents of IL-1β, IL-6 and IFN-γ and IL-4 in serum were measured and changes of adrenocorticotropic hormone (ACTH) and glucocorticoid (GC) in serum were analyzed by using enzyme-linked immunosorbent assay and radioimmunologic assay, respectively at different time points post wound and radiation.

RESULTS(1) The level of IFN-γ, one of the Th1 cell cytokines increased significantly at 14 d post CWR, which was markedly higher than that in control group and wound group. However, the level of IL-4, IL-1β and IL-6, one of the Th2 cell cytokines, did not show obvious change. (2) Ratio of Th1/Th2 (IFN-γ/IL-4) in wound group and CWR group increased significantly at 7 d after wound and radiation, which suggested that Th1/Th2 balance drifted to Th1 immune response. The ratio of Th1/Th2 in wound group returned to the normal level up to 14 d after the wound and radiation, while the Th1/Th2 ratio in CWR group increased persistently and was much higher than that in control and wound groups. (3) Level of serous ACTH and GC in CWR group increased at 3 d post wound and radiation, and among them, level of GC showed statistically significant increase, which was much higher than that in control and wound groups.

CONCLUSIONLevel of serous neurohormone GC in rats increased significantly immediately after wound and radiation; while the level of IFN-γ showed significant increase only up to 14 d after wound and radiation, and the Th1/Th2 imbalance sustained till 28 d post wound and radiation. In order to reduce acute damage caused by CWR, organic immune system and nerve system showed up a marked regulate effects simultaneously and mutually. Nonetheless, the excessive stress induced by CWR causes disturbance of immunoregulation, which is one of the key reasons for delayed wound healing in CWR.

Objective To investigate the efficacy of Kuntai capsules combined with tibolone in treating menopausal syndrome. Methods 80 cases of gynaecology patients from January 2014 to December 2016 were selected and randomly divided into the treatment group and the control group, 40 cases in each group. The treatment group was given Kuntai capsules combined with tibolone, the control group was given tibolone. Results After treatment,the Kupperman scores of the two groups were better than before treatment (P<0.05), the total effective of the treatment group was significantly higher than that of the control group (P<0.05). The number of women who reduced dosage of tibolone in the treatment group was more than in the control group (P<0.05). Conclusion Kuntai capsules combined with tibolone is better in treating menopausal syndrome than tibolone treatment.

Objective To investigate the application of the fluorescein diacetate (FDA) microplate assay in cell viability detection. Methods Cells were seeded in a 96-well culture plate until detection. After incubated with FDA,the plate was detected by fluorescence microplate analyzer. The effects of FDA incubation duration,concentration,and other factors on the assay's accuracy and stability were assessed. We also compared the results of FDA with methyl thiazolyl(MTT) in terms of cell numbers and HOinjury. Results Within 0-30 minutes,the fluorescence-cell number coefficient of FDA assay increased with duration and reached 0.99 in 27-30 minutes. The optimum concentration of final FDA in this study was 10-30 μg/ml. On cell viability detection,the result of FDA method was equivalent to MTT method. As to HOinjury assay,the sensitivity of FDA method was superior to MTT on the higher concentration HOtreatment due to a relative shorter duration for detection. Conclusion As a stable and reliable method,FDA is feasible for cell variability detection under varied conditions.

BACKGROUNDThis study evaluated the efficacy of percutaneous nucleoplasty using coblation technique for the treatment of chronic nonspecific low back pain (LBP), after 5 years of follow-up.

METHODSFrom September 2004 to November 2006, 172 patients underwent percutaneous nucleoplasty for chronic LBP in our department. Forty-one of these patients were followed up for a mean period of 67 months. Nucleoplasty was performed at L3/4 in 1 patient; L4/5 in 25 patients; L5/S1 in 2 patients; L3/4 and L4/5 in 2 patients; L4/5 and L5/S1 in 7 patients; and L3/4, L4/5, and L5/S1 in 4 patients. Patients were assessed preoperatively and at 1 week, 1 year, 3 years, and 5 years postoperatively. Pain was graded using a 10-cm Visual Analogue Scale (VAS) and the percentage reduction in pain score was calculated at each postoperative time point. The Oswestry Disability Index (ODI) was used to assess disability-related to lumbar spine degeneration, and patient satisfaction was assessed using the modified MacNab criteria.

RESULTSThere were significant differences among the preoperative, 1-week postoperative, and 3-year postoperative VAS and ODI scores, but not between the 3- and 5-year postoperative scores. There were no significant differences in age, sex, or preoperative symptoms between patients with effective and ineffective treatment, but there were significant differences in the number of levels treated, Pfirrmann grade of intervertebral disc degeneration, and provocative discography findings between these two groups. Excellent or good patient satisfaction was achieved in 87.9% of patients after 1 week, 72.4% after 1 year, 67.7% after 3 years, and 63.4% at the last follow-up.

CONCLUSIONSAlthough previously published short- and medium-term outcomes after percutaneous nucleoplasty appeared to be satisfactory, our long-term follow-up results show a significant decline in patient satisfaction over time. Percutaneous nucleoplasty is a safe and simple technique, with therapeutic effectiveness for the treatment of chronic LBP in selected patients. The technique is minimally invasive and can be used as part of a stepwise treatment plan for chronic LBP.
