Endometriosis is a common, estrogen-dependent, inflammatory, gynecologic disease process in which normal endometrial tissue is abnormally present outside the uterine cavity. [1] Endometriosis is a common cause of chronic pain, dyspareunia, dysmenorrhea, and infertility. Most commonly, endometriosis is found within the pelvis, specifically on the ovaries. Because of rupture, bleeding, infection, or torsion, ovarian endometriosis (OMA) may cause acute abdominal pain, which is similar to acute abdominal pain caused by other reasons and is not easy to diagnose.[2,3] Determining the clinical and pathological features of OMA is crucial for accurate assessment, diagnosis, and treatment.

Objective: To determine the inhibitory effects of pachymic acid on lung adenocarcinoma (LUAD) cells and elucidate its underlying mechanism. Methods: CCK-8, wound healing, Transwell, Western blot, tube formation, and immunofluorescence assays were carried out to measure the effects of various concentrations of pachymic acid on LUAD cell proliferation, metastasis, angiogenesis as well as autophagy. Subsequently, molecular docking technology was used to detect the potential targeted binding association between pachymic acid and protein tyrosine phosphatase 1B (PTP1B). Moreover, PTP1B was overexpressed in A549 cells to detect the specific mechanisms of pachymic acid. Results: Pachymic acid suppressed LUAD cell viability, metastasis as well as angiogenesis while inducing cell autophagy. It also targeted PTP1B and lowered PTP1B expression. However, PTP1B overexpression reversed the effects of pachymic acid on metastasis, angiogenesis, and autophagy as well as the expression of Wnt3a and β-catenin in LUAD cells. Conclusions: Pachymic acid inhibits metastasis and angiogenesis, and promotes autophagy in LUAD cells by modulating the Wnt/ β-catenin signaling pathway via targeting PTP1B.

The early life period is a rapid period, as well as a critical/sensitive period for brain development. Proteins, long-chain polyunsaturated fatty acids (LCPUFAs), iron, zinc, iodine, folate, choline, vitamins A, D, B6, and B12, all play a role in key neural development processes and thus influence brain development. Different brain regions or circuits have specific critical periods during different stages of development that depend on specific nutrients. Any nutrient deficiency during this period, even if corrected with supplementation, may still affect the trajectory of brain development and result in long-term cognitive and behavioral impairment. This article elucidates the effects of major nutrient deficiencies during early life on brain development, the possible sensitive/critical timing, and the impacts on long-term cognitive and behavioral development, providing insights for the prevention and intervention of nutritional diseases and psychiatric developmental disorders, and the promotion of early childhood development.

Objective To investigate the effect of programmed death ligand-1(PD-L1)overexpression on epithelial mesenchymal transformation(EMT)in endometrial cancer cells and its possible mechanism.Methods Ishikawa/PD-L1,a PD-L1 stable overexpression cell line constructed in the laboratory and the control Ishikawa/EV were used.The efficiency of PD-L1 overexpression was detected by qPCR and Western blot assay.The cell migration ability and invasion activity were detected by scratch assay and Transwell assay.The EMT-related protein and the phosphorylation level of nuclear transcription factor-κB(NF-κB)were detected by Western blot.Results Compared with the control group,the migration ability and invasion activity of Ishikawa/PD-L1 were significantly enhanced,and the expression of E-cadherin was significantly down-regulated,whereas vimentin,N-cadherin and p-p65 were significantly increased.Conclusion PD-L1 can promote EMT by inducing the activation of NF-κB pathway,and thus enhance the migration and invasion ability of endometrial cancer cells.

Objective To analyze the distribution of common allergens in children with allergic rhinitis(AR)in Hangzhou,and to provide reference for its prevention and treatment.Methods From January 2020 to December 2022,13 521 children who were diagnosed with AR and underwent in vitro serum specific immunoglobulin E(sIgE)detection in Affiliated Hangzhou First People's Hospital,School of Medicine,Westlake University were selected as the research objects.The positive rates of allergens in children with AR of different genders,ages and seasons were compared.Results Among 13 521 children,the positive rate of sIgE was 54.49%(7367/13 521),of which 64.82%were allergic to only one allergen.Among the 19 common allergens,the top three overall positive rates were household dust mite(44.27%),milk(14.62%),and mixed grass(4.82%).The positive rates of allergens of house dust mites,cat hair dander,mulberry,mold combination,tree pollen combination,amaranth,cockroach,milk,shrimp,crab,pineapple,shellfish and mango in male children were significantly higher than those in female children(P<0.05).The positive rates of allergens of house dust mite,mixed grass,cat hair dander,mulberry,mold combination,egg white,shrimp,crab,pineapple,cashew nuts and shellfish in different age groups were statistically significant(P<0.05).July and August were the two months with the highest allergen positive rate.The allergen positive rates of house dust mite,dog and cat hair dander were the highest in summer,and the allergen positive rate of plants was consistent with the flowering season.The sIgE concentration of house dust mite(77.87%)was mainly grade 3 and above.The sIgE concentration of other allergens was mainly grade 1 and 2.Conclusion Dust mites and milk are the most common allergens in children with AR in Hangzhou,and the distribution of allergens varies with gender,age and season.Allergen detection can provide a more accurate plan for the diagnosis,prevention and treatment of AR.

Disseminated intravascular coagulation (DIC) is a clinical syndrome caused by various etiologies and characterized by systemic activation of blood coagulation, leading to vessel thrombosis, organ dysfunction, and severe bleeding.[1] DIC represents a life-threatening condition that is the endpoint of uncontrolled systemic activation of the disease. Once it enters the stage of malignant DIC, the patient’s death becomes unavoidable. DIC always occurs as a secondary disorder and is commonly associated with postpartum hemorrhage, followed by hypertensive disorders, acute fatty liver of pregnancy, sepsis, and amniotic fluid embolism (AFE).[2] In clinical obstetrics, DIC often occurs during delivery or postpartum, while cases of prenatal acute DIC as the first manifestation are uncommon. Patients with DIC have higher rates of multiple organ dysfunction syndrome, including acute renal failure (ARF), respiratory failure, and disturbance of consciousness.

OBJECTIVE To explore the practice mode of cough and asthma pharmacy clinic in Affiliates Hangzhou First People's Hospital, Zhejiang University, School of Medicine. METHODS To set up a cough and asthma pharmacy clinic, equipped with corresponding hardware and software facilities, and establish a cough and asthma pharmaceutical care mode. From December 1, 2020 to August 31, 2022, 2 357 patients in the hospital cough and asthma pharmacy clinic were collected, and their general data were analyzed. The patients learned by themselves according to the inhalation video, and then were guided by pharmacists to evaluate the differences in the use skills of patients before and after the intervention of pharmacists. The 345 patients with chronic obstructive pulmonary disease who were treated in the cough and asthma pharmacy clinic from December 1, 2020 to July 31, 2021 were collected. They were divided into 30 d follow-up group(n=173) and 15 d follow-up group(n=172) according to the blind sampling method. The score difference of Morisky medication Compliance Scale(MMAS-8) at 1, 3, 6 and 12 months of follow-up was compared. RESULTS Among 2 357 patients, 1 213(51.46%) were males and 1 144(48.54%) were females, 1 309 cases(55.54%) aged ≥60 years old, 563 cases(23.89%) aged 40-59 years old, 402 cases(17.06%) aged 20-39 years old, 32 cases(1.36%) aged 14-20 years old, and 51 cases(2.16%) aged＜14 years old. The main diseases of the patients were chronic obstructive pulmonary disease(55.38%) and asthma(20.73%). Budesonide and Formoterol Fumarate powder for inhalation(37.08%) and Budesonide, Glycopyrronium Bromide and Formoterol Fumarate Inhalation Aerosol(25.84%) were frequently used. On the basis of patients' video teaching, pharmacists' mastery of inhaler use skills was better than that of patients' self-learning through video. The score before intervention was 5.360±1.208 and that after intervention was 7.890±0.356. There was significant difference between the two groups(P＜0.05). At a month of follow-up, the MMAS-8 score of the 15-day follow-up group was 6.310±1.079. The MMAS-8 score of the 30 d follow-up group was 5.250±0.977, there was a significant difference between the two groups(P＜0.05), but there was no significant difference in the MMAS-8 score of the two groups at 3, 6, 12-month follow-up. CONCLUSION The establishment of cough and asthma pharmacy clinic promotes the integration of pharmacy and respiratory clinical discipline, and improves the medication compliance of patients.

  Objective  To understand the current status of surgical treatment for hemophilia osteoarthropathy (HO) in China.  Methods  Using an online questionnaire, select domestic hospitals that partici-pated in the compilation of the 'Guideline for perioperative management of hemophilia patients undergoing orthopaedic surgery in China ', in addition to members of the National Joint Surgery Group, and the Orthopedic Branch of the Chinese Medical Association for targeted investigation and analysis.  Results  A total of 17 domestic hospitals were included, all of which were general hospitals. Hospitals that started HO surgery treatment before 2000 accounted for 35.29%. A total of 3057 surgical cases of HO were reported by those hospitals. The most commonly performed surgical procedures were hip and knee joint replacement. The most commonly used coagulation factor replacement regimen was recombinant coagulation factor preparation. Ten hospitals reported finding patients with transfusion-related infectious diseases. Bleeding and hematoma formation were the most frequently reported surgical complications. Excessive length of hospital stay and high economic costs were the most frequently reported problems.  Conclusions  Surgical treatment for HO in 17 hospitals is mainly carried out in some large comprehensive medical centers in the eastern region. Compared with the patient base, the popularity and number of surgeries are still relatively insufficient. It is necessary to further standardize the treatment system by standardizing factor replacement and strengthening rehabilitation to improve surgical treatment outcomes.

We aimed to evaluate the effectiveness and safety of single-course initial regimens in patients with low-risk gestational trophoblastic neoplasia (GTN). In this trial (NCT01823315), 276 patients were analyzed. Patients were allocated to three initiated regimens: single-course methotrexate (MTX), single-course MTX + dactinomycin (ACTD), and multi-course MTX (control arm). The primary endpoint was the complete remission (CR) rate by initial drug(s). The primary CR rate was 64.4% with multi-course MTX in the control arm. For the single-course MTX arm, the CR rate was 35.8% by one course; it increased to 59.3% after subsequent multi-course MTX, with non-inferiority to the control (difference -5.1%,95% confidence interval (CI) -19.4% to 9.2%, P = 0.014). After further treatment with multi-course ACTD, the CR rate (93.3%) was similar to that of the control (95.2%, P = 0.577). For the single-course MTX + ACTD arm, the CR rate was 46.7% by one course, which increased to 89.1% after subsequent multi-course, with non-inferiority (difference 24.7%, 95% CI 12.8%-36.6%, P < 0.001) to the control. It was similar to the CR rate by MTX and further ACTD in the control arm (89.1% vs. 95.2%, P =0.135). Four patients experienced recurrence, with no death, during the 2-year follow-up. We demonstrated that chemotherapy initiation with single-course MTX may be an alternative regimen for patients with low-risk GTN.

Observation indicators: (1) the incidence of POPF after radical gastrectomy; (2) treatment of grade B POPF after radical gastrectomy; (3) analysis of clinicopathological data; (4) analysis of surgical data; (5) risk factors for grade B POPF after radical gastrectomy. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using ANOVA. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate analysis was conducted using the t test or chi-square test based on data excluding missing data of clinico-pathological and surgical data. Multivariate analysis was conducted using the Logistic regression model based on factors with P<0.20 in univariate analysis. Results: There were 2 089 patients screened for eligibility, including 1 512 males, 576 females and 1 without sex information, aged (62±11)years. The body mass index (BMI) was (23±3)kg/m². (1) The incidence of POPF after radical gastrectomy: the total incidence rate of POPF in the 2 089 patients was 20.728%(433/2 089). The incidence rates of biochemical fistula, grade B pancreatic fistula, and grade C pancreatic fistula were 19.627%(410/2 089), 1.101%(23/2 089), 0, respectively. (2) Treatment of grade B POPF after radical gastrectomy: 2 of 23 patients with grade B POPF after radical gastrectomy had drainage tube placed for more than 21 days and received anti-infective therapy. Four of 23 patients with grade B POPF after radical gastrectomy had ascites detected by imaging examination, of which 2 received peritoneal drainage guided by ultrasound, 1 received failed puncture drainage, 1 received no puncture drainage, and they were given anti-infective therapy. Eleven of 23 patients with grade B POPF after radical gastrectomy had no ascites detected by imaging examinations, and they were given anti-infective therapy and inhibitors of pancreas secretion for clinical manifestation as fever or elevated white blood cells. Six patients with no typical clinical manifestations were given somatostatin to inhibite pancreas secretion and prolonged duration of abdominal drainage tube placement (with a median time of 7 days). All the 23 patients recovered well after treatment, without reoperation. (3) Analysis of clinicopathological data: for the 2 089 patients, BMI, cases with or without neoadjuvant therapy were (23±3)kg/m^2, 1 487, 160 of patients without pancreatic fistula, (23±3)kg/m^2, 386, 22 of patients with biochemical fistula, and (24±3)kg/m^2, 22, 1 of patents with grade B pancreatic fistula, showing significant differences between the three groups (F=5.787, χ²=8.269, P<0.05). (4) Analysis of surgical data: for the 2 089 patients, cases with open surgery, laparoscopic assisted surgery, totally laparoscopic surgery (surgical method), cases with D₁ lymph lode dissection, D₂ lymph lode dissection, and other lymph lode dissection (range of lymph lode dissection), cases with no omentectomy, partial omentectomy, and total omentectomy (range of omentectomy), cases with no usage of energy facility, usage of CUSA, LigaSure, LigaSure+ CUSA as energy facility, cases with or without biological glue, the number of lymph node dissection were 737, 624, 292, 24, 1 580, 51, 418, 834, 381, 63, 1 530, 23, 16, 1 431, 201, 33±14 of patients without pancreatic fistula, 146, 189, 74, 11, 389, 9, 110, 171, 128, 35, 359, 6, 9, 378, 31, 31±14 of patients with biochemical fistula, and 14, 5, 4, 0, 20, 3, 6, 13, 4, 2, 18, 1, 2, 22, 1, 37±16 of patients with grade B pancreatic fistula, showing significant differences between the three groups (χ²=15.578, 9.397, 15.023, 28.245, 8.359, F=4.945, P<0.05). (5) Risk factors for grade B POPF after radical gastrectomy: results of univariate analysis showed that usage of energy facility was a related factor for grade B POPF after radical gastrectomy (χ²=9.914, P<0.05). Results of multivariate analysis showed that laparoscopic assisted surgery, combined evisceration, application of LigaSure + CUSA, the number of lymph lode dissection were independent factors for for grade B POPF after radical gastrectomy (odds ratio=0.168, 3.922, 9.250, 1.030, 95% confidence interval: 0.036-0.789, 1.031-14.919, 1.036-82.602, 1.001-1.059, P<0.05). Conclusions The incidence of grade B POPF after radical gastrectomy is relatively low. Laparoscopic assisted surgery, combined evisceration, application of LigaSure + CUSA, and the number of lymph lode dissection are independent risk factors for grade B POPF.
