Objective To investigate the effect of Zheng's 4C suspension transumbilical laparoendoscopic single-site surgery(TU-LSSS)in the treatment of cervical cancer,and analyze its prognosis.Methods A total of 92 patients with cervical cancer admitted to our hospital were selected and randomly divided into the control group(traditional laparoscopic surgery)and the observation group(Zheng's 4C suspension TU-LSSS),with 46 cases in each group.The perioperative related indicators of patients between the two groups were compared.The patients were followed up for 3 years,the progression-free survival(PFS)and overall survival(OS)were recorded,and the influencing factors of prognosis were analyzed.Results Compared with the control group,patients in the observation group had longer surgical time(P<0.05),less intraoperative bleeding(P<0.05),shorter recovery time for postoperative bowel sounds and hospital stay(P<0.05),higher postoperative 3-year PFS rate and 3-year OS rate(P<0.05).During 3-year follow-up,there were 11 cases of disease progression or death.The univariate analysis results showed that there were statistically significant differences in tumor diameter,clinical stage,lymph node metastasis,vascular infiltration,and treatment methods of patients between the good prognosis group and the poor prognosis group(P<0.05).The binary Logistic regression results showed that tumor diameter(≥4 cm),clinical stage(≥stage ⅠB2),lymph node metastasis,and vascular infiltration were the risk factors for the prognosis of patietns with cervical cancer(P<0.05),while Zheng's 4C suspension TU-LSSS was the protective factors(P<0.05).Conclusion Zheng's 4C suspension TU-LSSS can effectively promote the recovery of patients with cervical cancer,and improve 3-year PFS rate and 3-year OS rate.The prognosis is related to many factors,and targeted treatment should be performed according to different risk factors.

This study aims to examine the effect of superfine powder and aqueous extract of Polygonati Rhizomaon on natural perimenopausal syndrome in rats and explore the underlying mechanism. To be specific, a total of 60 female SD rats(14-15 months old) with estrous cycle disorder were screened by the vaginal smear and randomized into model control group, β-estradiol 3-benzoate group(0.1 mg·kg~(-1)), superfine powder of Polygonati Rhizoma group(0.25, 0.5 g·kg~(-1)) and aqueous extract of Polygonati Rhizoma group(0.25, 0.5 g·kg~(-1)), and another 10 female SD rats(14-15 months old) were selected as the youth control group. The administration lasted 6 weeks. Then the perimenopausal syndrome-related indexes such as body temperature, microcirculatory blood flow of face and ear, vertigo period, salivary secretion, grip force, and bone strength were determined and open field test was conducted. The immune system-related indexes such as the wet weight and index of thymus and spleen, percentage of T lymphocytes and subgroups in peripheral blood, and hematological indexes were measured. In addition, the ovary-related indexes such as estrous cycle, the wet weight and index of uterus and ovary, ovarian tissue morphology, and cell apoptosis were determined. Moreover, hypothalamus-pituitary-ovary axis(HPO)-related indexes such as serum sex hormone levels, cytochrome P450 family 11 subfamily A member 1(CYP11A1), cytochrome P450 family 19 subfamily A member 1(CYP19A1), and cytochrome P450 family 17 subfamily A member 1(P450 17A1) in ovarian tissue were measured. The results showed that the superfine powder and aqueous extract of Polygonati Rhizoma significantly decreased body temperature(anal, facial and dorsal temperature), microcirculatory blood flow in the ear, and vertigo period, increased salivary secretion, grip force, bone strength, total distance and total speed in the open field test, wet weight and index of thymus and spleen, lymphocyte ratio, CD3~+ level, and CD4~+/CD8~+ ratio, reduced neutrophil number and ratio, estrous cycle disorder ratio, and number of ovarian apoptotic cells, raised wet weight and index of uterus, wet weight of ovary, levels of inhibin B(INHB), estradiol(E_2), anti-müllerian hormone(AMH), and ovarian CYP11A1 and CYP19A1, decreased follicle-stimulating hormone(FSH) and luteinizing hormone(LH) content, and improved ovarian tissue morphology. It is suggested that the superfine powder and aqueous extract of Polygonati Rhizoma can improve the symptoms associated with natural perimenopausal syndrome in rats and enhance ovarian function and immune function. The mechanism is that they regulate HPO axis function by increasing estrogen synthesis.

Objective: Subthreshold attention-deficit/hyperactivity disorder (ADHD) has been suggested to be a “morbid condition” which also needs medical attention. Methods: The present study recruited 89 children with subthreshold ADHD (sADHD), 115 children with diagnosed ADHD (cADHD), and 79 healthy controls (HC) to explore the clinical manifestation, executive functions (EFs) of sADHD, and the caregiver strain. The clinical manifestation was evaluated through clinical interviews and parent-reports. Executive functions were assessed both experimentally and ecologically. Caregiver strain was measured by a parent-reported questionnaire. Results: For the clinical manifestation, both sADHD and cADHD indicated impairments when compared with HC. The comorbidities and the scaled symptoms indicated that the externalizing behaviors were relatively less serious in sADHD than cADHD, whereas the internalizing behaviors between two groups were comparable. For ecological EFs, sADHD scored between cADHD and HC in inhibition and working memory. For experimental EFs, sADHD was comparable to cADHD in inhibition, shifting, and was worse than cADHD in verbal working memory. For the caregiver strain, all scores of sADHD were between that in cADHD and that in HC. Conclusion Our present findings supported the suggestion of subthreshold ADHD as “morbid condition,” which should be treated with caution in clinical practice, especially for the internalizing behaviors and some key components of EFs.

Objective: To analyze the short-time efficacy of empagliflozin in the treatment of glycogen storage disease type Ⅰb (GSD Ⅰb). Methods: In this prospective open-label single-arm study, the data of 4 patients were collected from the pediatric department in Peking Union Medical College Hospital from December 2020 to December 2022. All of them were diagnosed by gene sequencing and had neutropenia. These patients received empagliflozin treatment. Their clinical symptoms such as height and weight increase, abdominal pain, diarrhea, oral ulcer, infection times, and drug applications were recorded at 2 weeks, 1 month, 2 months, 3 months, 6 months, 9 months, 12 months, and 15 months after treatment to assess the therapeutic effect. The liquid chromatography-tandem mass spectrometry method was used to monitor the changes in 1, 5-anhydroglucitol (1, 5AG) concentration in plasma. At the same time, adverse reactions such as hypoglycemia and urinary tract infection were closely followed up and monitored. Results: The 4 patients with GSD Ⅰb were 15, 14, 4 and 14 years old, respectively at the beginning of empagliflozin treatment, and were followed up for 15, 15, 12 and 6 months, respectively. Maintenance dose range of empagliflozin was 0.24-0.39 mg/(kg·d). The frequency of diarrhea and abdominal pain decreased in cases 2, 3, and 4 at 1, 2 and 3 months of treatment, respectively. Their height and weight increased at different degrees.The absolute count of neutrophils increased from 0.84×10⁹, 0.50×10⁹, 0.48×10⁹, 0.48×10⁹/L to 1.48×10⁹, 3.04×10⁹, 1.10×10⁹, 0.73×10⁹/L, respectively. Granulocyte colony-stimulating factor was gradually reduced in 1 patients and stopped in 3 patient. Plasma 1, 5 AG levels in 2 children were significantly decreased after administration of empagliflozin (from 46.3 mg/L to 9.6 mg/L in case 2, and from 56.1 mg/L to 15.0 mg/L in case 3). All 4 patients had no adverse reactions such as hypoglycemia, abnormal liver or kidney function, or urinary system infection. Conclusion: In short-term observation, empagliflozin can improve the symptoms of GSD Ⅰb oral ulcers, abdominal pain, diarrhea, and recurrent infection, also can alleviate neutropenia and decrease 1, 5AG concentration in plasma, with favorable safety.

OBJECTIVES: To examine the changes of intestinal flora in children newly diagnosed with acute lymphoblastic leukemia (ALL) and the influence of chemotherapy on intestinal flora. METHODS: Fecal samples were collected from 40 children newly diagnosed with ALL before chemotherapy and at 2 weeks, 1 month, and 2 months after chemotherapy. Ten healthy children served as the control group. 16S rDNA sequencing and analysis were performed to compare the differences in intestinal flora between the ALL and control groups and children with ALL before and after chemotherapy. RESULTS: The ALL group had a significant reduction in the abundance of intestinal flora at 1 and 2 months after chemotherapy, with a significant reduction compared with the control group (P<0.05). Compared with the control group, the ALL group had a significant reduction in the diversity of intestinal flora before and after chemotherapy (P<0.05). At the phylum level, compared with the control group, the ALL group had a significant reduction in the relative abundance of Actinobacteria at 2 weeks, 1 month, and 2 months after chemotherapy (P<0.05) and a significant increase in the relative abundance of Proteobacteria at 1 and 2 months after chemotherapy (P<0.05). At the genus level, compared with the control group, the ALL group had a significant reduction in the relative abundance of Bifidobacterium at 2 weeks, 1 month, and 2 months after chemotherapy (P<0.05); the relative abundance of Klebsiella in the ALL group was significantly higher than that in the control group at 1 and 2 months after chemotherapy and showed a significant increase at 1 month after chemotherapy (P<0.05); the relative abundance of Faecalibacterium in the ALL group was significantly lower than that in the control group before and after chemotherapy and showed a significant reduction at 2 weeks and 1 month after chemotherapy (P<0.05). The relative abundance of Enterococcus increased significantly at 1 and 2 months after chemotherapy in the ALL group (P<0.05), and was significantly higher than that in the control group (P<0.05). CONCLUSIONS The diversity of intestinal flora in children with ALL is significantly lower than that in healthy children. Chemotherapy significantly reduces the abundance of intestinal flora and can reduce the abundance of some probiotic bacteria (Bifidobacterium and Faecalibacterium) and increase the abundance of pathogenic bacteria (Klebsiella and Enterococcus) in children with ALL.

Objective: To estimate the incidence of HIV-1 infection in men who have sex with men (MSM) in key areas of China through HIV-1 limiting antigen avidity enzyme immunoassay (LAg-Avidity EIA), analyze the deviation from the actual results and identify influencing factors, and provided reference for improving the accuracy of estimation results. Methods: Based on the principle of the cohort randomized study design, 20 cities were selected in China based on population size and the number of HIV-positive MSM. The sample size was estimated to be 700 according to the HIV-1 infection rate in MSM. MSM mobile phone app. was used to establish a detection appointment and questionnaire system, and the baseline cross-sectional survey was conducted from April to November 2019. LAg-Avidity EIA was used to identify the recent infected samples. The incidence of HIV-1 infection was calculated and then adjusted based on the estimation formula designed by WHO. The influencing factors were identified by analyzing the sample collection and detection processes. Results: Among the 10 650 blood samples from the participants, 799 were HIV-positive in initial screening, in which 198 samples (24.78%) missed during confirmation test. Only 621 samples were received by the laboratory. After excluding misreported samples, 520 samples were qualified for testing. A total of 155 samples were eventually determined as recent infection through LAg-Avidity EIA; Based on the estimation formula , the incidence of HIV-1 infection in MSM in 20 cities was 4.06% (95%CI:3.27%-4.85%), it increased to 5.53% (95%CI: 4.45%-6.60%)after the adjusting for sample missing rate. When the sample missing rate and misreporting rate were both adjusted, the incidence of HIV-1 infection in the MSM increased to 5.66% (95%CI:4.67%-6.65%). The actual incidence of HIV-1 infection in MSM in the 20 cities might be between 4.06% and 5.66%. Conclusions: Sample missing and misreporting might cause the deviation of the estimation of HIV-1 infection incidence. It is important to ensure the sample source and the quality of sample collection and detection to reduce the deviation in the estimation of HIV-1 infection incidence.

Objectives: To investigate the clinical value of adjuvant chemotherapy(ACT) in patients with intrahepatic cholangiocarcinoma(ICC) who underwent radical resection and to explore the optimal population that can benefit from ACT. Methods: A retrospective cohort study method was adopted. The clinical and pathological data of 685 patients with ICC who underwent curative intent resection in 10 Chinese hepatobiliary surgery centers from January 2010 to December 2018 were collected;There were 355 males and 330 females. The age(M(IQR)) was 58(14) years (range: 22 to 83 years). Propensity score matching(PSM) was applied to balance the differences between the adjuvant and non-adjuvant chemotherapy groups. Log-rank test was used to compare the prognosis of the two groups of patients. A Bayesian network recurrence-free survival(RFS) prediction model was constructed using the median RFS time (14 months) as the target variable, and the importance of the relevant prognostic factors was ranked according to the multistate Birnbaum importance calculation. A survival prognostic prediction table was established to analyze the population benefiting from adjuvant chemotherapy. Results: Among 685 patients,214 received ACT and 471 did not receive ACT. A total of 124 pairs of patients were included after PSM, and patients in the ACT group had better overall survival (OS) and RFS than those in the non-ACT group(OS: 32.2 months vs. 18.0 months,P=0.003;RFS:18.0 months vs. 10.0 months,P=0.001). The area under the curve of the Bayesian network RFS prediction model was 0.7124. The results of the prognostic factors in order of importance were microvascular invasion (0.158 2),perineural invasion (0.158 2),N stage (0.155 8),T stage (0.120 9), hepatic envelope invasion (0.090 3),adjuvant chemotherapy (0.072 1), tumor location (0.057 5), age (0.042 3), pathological differentiation (0.034 0), sex (0.029 3), alpha-fetoprotein (0.028 9) and preoperative jaundice (0.008 5). A survival prediction table based on the variables with importance greater than 0.1 (microvascular invasion,perineural invasion,N stage,T staging) and ACT showed that all patients benefited from ACT (increase in the probability of RFS≥14 months from 2.21% to 7.68%), with a more significant increase in the probability of RFS≥14 months after ACT in early-stage patients. Conclusion: ACT after radical resection in patients with ICC significantly prolongs the OS and RFS of patients, and the benefit of ACT is greater in early patients.

Through the combing of ancient books of Chinese herbal medicine in the past dynasties， a textual research of Coptidis Rhizoma involved the name， origin， medicinal parts， producing area， quality evaluation， harvesting and processing methods in famous classical formulas was conducted in this paper. After textual research， the mainstream varieties of Coptidis Rhizoma in the Ranunculaceae family before Tang and Song dynasties were Coptis chinensis and C. chinensis var. brevisepala， after the Ming and Qing dynasties， C. deltoidea， C. teeta and C. omeiensis were gradually praised. In ancient times， the authentic producing area of Coptidis Rhizoma has the characteristics of gradually moving to the west. The eastern Coptidis Rhizoma was highly praised in the early stage， while in the later stage， western Coptidis Rhizoma like chicken feet was highly praised. In the early stage， western Coptidis Rhizoma probably originated from C. chinensis and its genus， while Coptidis Rhizoma like chicken feet was cultivated， and no wild species has been found so far. As Coptidis Rhizoma has mixed use of multiple origins in ancient books of past dynasties， based on the current shortage of market resources in C. teeta and C. deltoidea， there are also endangered and protected plants of C. chinensis var. brevisepala and C. omeiensis， combined with the mainstream medicines and resources of past generations， it is recommended to choose C. chinensis as the base of the formulas. In ancient times， there were many processing methods for Coptidis Rhizoma， such as frying and wine-， ginger-， honey-processed. In the process of developing famous classical formulas， the appropriate processing specifications of Coptidis Rhizoma should be selected based on the original source records and the requirements of the medicinal material.

This study aimed to investigate the effect of microRNA-155 (miR-155) in chronic obstructive pulmonary disease (COPD) and cigarette smoke extract (CSE)-treated airway smooth muscle cells (ASMCs) by targeting phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1) to regulate the PTEN/PI3K/Akt signaling pathway. The COPD mouse model was induced by lipopolysaccharide (LPS) combined with passive smoking. After modeling, miR-155 mimics and miR-155 inhibitor were used for intervention treatment. The pulmonary function of each group was detected by an EMKA detector. Hematoxylin-eosin (HE) staining was used to observe the pathological changes and scores of lung tissues. The expression of TNF-α, IL-6, and IL-1β in bronchial alveolar lavage fluid (BALF) was detected by ELISA. Primary ASMCs were isolated and cultured in adherent tissue culture. The proliferation activity was detected by CCK-8 and EdU assays. Transwell and wound healing assays were used to measure the migration of ASMCs. The targeting relationship between miR-155 and PIK3R1 was validated by a double luciferase reporter gene assay. The expression levels of miR-155 and PIK3R1 mRNA in lung tissues of mice in each group were detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Western blot was used to detect the expression levels of Ki67, PNCA, PTEN, p-PI3K, PI3K, p85α, p-Akt, and Akt in lung tissues and ASMCs. The results showed that lung function was significantly reduced in the miR-155 mimic group, and the levels of PIK3R1 were significantly increased; while lung function in the miR-155 inhibitor group was significantly improved. The results of HE staining showed that there was obvious inflammatory cell infiltration in the miR-155 mimics group compared to that of the model group. Lung histopathological injury was significantly reduced in the miR-155 inhibitor group, accompanied by decreased expression of Ki67, PNCA, PI3K, p-Akt, increased PTEN and p85α protein levels, and reduced levels of TNF-α, IL-6, and IL-1β in BALF. The results of the double luciferase reporter gene assay showed that miRNA-155 could target bind to PIK3R1. Compared with those in the CSE+miR-155 NC group, the proliferation and migration of ASMCs were significantly increased in the CSE+miR-155 group. The proliferation and migration of ASMCs were significantly attenuated in the CSE+miR-155+pcDNA PIK3R1 group compared with those in the CSE+miR-155 group, accompanied by decreased expression of Ki67, PNCA, p-Akt and increased PTEN and p85α protein levels. These results suggest that miR-155 activates the PTEN/PI3K/Akt signaling pathway by targeting PIK3R1 to promote the occurrence and development of COPD, which provides new evidence for the use of miR-155 in the treatment of COPD.
