ABSTRACT

Objective: To compare the effects and safety of dydrogesterone (DG) and medroxyprogesterone acetate (MPA) on the treatment in patients with endometrial hyperplasia without atypia (EH). Methods: This was a single-center, open-label, prospective non-inferior randomized controlled phase Ⅲ trial. From February 2019 to November 2021, patients with EH admitted to the Obstetrics and Gynecology Hospital of Fudan University were recruited. Enrolled patients were stratified according to the pathological types of simple hyperplasia (SH) or complex hyperplasia (CH), and were randomised to receive MPA or DG. Untill May 14, 2022, the median follow-up time after complete response (CR) was 9.3 months (1.1-17.2 months). The primary endpoint was the 6-month CR rate (6m-CR rate). The secondary endpoints included the 3-month CR rate (3m-CR rate), adverse events rate, recurrence rate, and pregnancy rate in one year after CR. Results: (1) A total of 292 patients with EH were enrolled in the study with the median age of 39 years (31-45 years). A total of 135 SH patients were randomly assigned to MPA group (n=67) and DG group (n=68), and 157 CH patients were randomly assigned to MPA group (n=79) and DG group (n=78). (2) Among 292 patients, 205 patients enrolled into the primary endpoint analysis, including 92 SH patients and 113 CH patients, with 100 patients in MPA group and 105 in DG group, respectively. The 6m-CR rate of MPA group and DG group were 90.0% (90/100) and 88.6% (93/105) respectively, and there were no statistical significance (χ2=0.11, P=0.741), with the rate difference (RD) was -1.4% (95%CI:-9.9%-7.0%). Stratified by the pathology types, the 6m-CR rate of SH patients was 93.5% (86/92), and MPA group and DG group were respectively 91.1% (41/45) and 95.7% (45/47); and the 6m-CR rate of CH patients was 85.8% (97/113), and MPA group and DG group were 89.1% (49/55) and 82.8% (48/58) respectively. The 6m-CR rates of the two treatments had no statistical significance either (all P>0.05). A total of 194 EH patients enrolled into the secondary endpoint analysis, including 88 SH patients and 106 CH patients, and 96 patients in MPA group and 98 in DG group, respectively. The 3m-CR rate of SH patients were 87.5% (77/88), while the 3m-CR rates of MPA group and DG group were 90.7% (39/43) and 84.4% (38/45), respectively; the 3m-CR rate of CH patients was 66.0% (70/106), and MPA group and DG group had the same 3m-CR rate of 66.0% (35/53). No statistical significance was found between the two treatments both in SH and CH patients (all P>0.05). (3) The incidence of adverse events between MPA group and DG group had no statistical significance (P>0.05). (4) A total of 93 SH patients achieved CR, and the cumulative recurrence rate in one year after CR were 5.9% and 0 in MPA group and DG group, respectively. While 112 CH patients achieved CR, and the cumulative recurrence rate in one year after CR were 8.8% and 6.5% in MPA group and DG group, respectively. There were no statistical significance between two treatment groups (all P>0.05). Among the 93 SH patients, 10 patients had family planning but no pregnancy happened during the follow-up period. Among the 112 CH patients, 21 were actively preparing for pregnancy, and the pregnancy rate and live-birth rate in one year after CR in MPA group were 7/9 and 2/7, while in DG group were respectively 4/12 and 2/4, and there were no statistical significance in pregnancy rate and live-birth rate between the two treatment groups (all P>0.05). Conclusions: Compared with MPA, DG is of good efficacy and safety in treating EH. DG is a favorable alternative treatment for EH patients.

ABSTRACT

OBJECTIVE@#To explore the incidence of azoospermia factor c (AZFc) microdeletion among patients with azoospermia or severe oligospermia, its association with sex hormone/chromosomal karyotype, and its effect on the outcome of pregnancy following intracytoplasmic sperm injection (ICSI) treatment.@*METHODS@#A total of 1 364 males with azoospermia or severe oligospermia who presented at the Affiliated Maternity and Child Health Care Hospital of Jiaxing College between 2013 and 2020 were subjected to AZF microdeletion and chromosome karyotyping analysis. The level of reproductive hormones in patients with AZFc deletions was compared with those of control groups A (with normal sperm indices) and B (azoospermia or severe oligospermia without AZFc microdeletion). The outcome of pregnancies for the AZFc-ICSI couples was compared with that of the control groups in regard to fertilization rate, superior embryo rate and clinical pregnancy rate.@*RESULTS@#A total of 51 patients were found to harbor AZFc microdeletion, which yielded a detection rate of 3.74%. Seven patients also had chromosomal aberrations. Compared with control group A, patients with AZFc deletion had higher levels of PRL, FSH and LH (P < 0.05), whilst compared with control group B, only the PRL and FSH were increased (P < 0.05). Twenty two AZFc couples underwent ICSI treatment, and no significant difference was found in the rate of superior embryos and clinical pregnancy between the AZFc-ICSI couples and the control group (P > 0.05).@*CONCLUSION@#The incidence of AZFc microdeletion was 3.74% among patients with azoospermia or severe oligospermia. AZFc microdeletion was associated with chromosomal aberrations and increased levels of PRL, FSH and LH, but did not affect the clinical pregnancy rate after ICSI treatment.

ABSTRACT

Purpose@#Cerebral ischemia is related to insufficient blood supply and is characterized by abnormal reactive oxygen species (ROS) production and cell apoptosis. Previous studies have revealed a key role for basic helix-loop-helix family member e40 (Bhlhe40) in oxidative stress and cell apoptosis. This study aimed to investigate the roles of miR-494-3p in cerebral ischemia/reperfusion (I/R) injury. @*Materials and Methods@#A mouse middle cerebral artery occlusion (MCAO/R) model was established to mimic cerebral ischemia in vivo. Brain infarct area was assessed using triphenyl tetrazolium chloride staining. Oxygen-glucose deprivation/reoxygenation (OGD/R) operation was adopted to mimic neuronal injury in vitro. Cell apoptosis was analyzed by flow cytometry. The relationship between miR-494-3p and Bhlhe40 was validated by luciferase reporter and RNA immunoprecipitation assays. @*Results@#Bhlhe40 expression was downregulated both in MCAO/R animal models and OGD/R-induced SH-SY5Y cells. Bhlhe40 overexpression inhibited cell apoptosis and reduced ROS production in SH-SY5Y cells after OGD/R treatment. MiR-494-3p was verified to bind to Bhlhe40 and negatively regulate Bhlhe40 expression. Additionally, cell apoptosis and ROS production in OGD/ R-treated SH-SY5Y cells were accelerated by miR-494-3p overexpression. Rescue experiments suggested that Bhlhe40 could reverse the effects of miR-494-3p overexpression on ROS production and cell apoptosis. @*Conclusion@#MiR-494-3p exacerbates brain injury and neuronal injury by regulating Bhlhe40 after I/R.

ABSTRACT

Clinical trials of anti-tumor drugs is not only the important way to develop new drugs, but also the most advanced treatment methods for malignant tumors, bringing survival benefits to patients. There are a large number of new anti-tumor drug clinical trials for lung cancer patients, covering a wide variety of anti-tumor drugs, and with rapid progress and high efficiency of clinical transformation. These trials could not be carried out successfully without the joint efforts of the research team, in which the research nurses also played a role that should not be underestimated. Combined with the work content of clinical research nurses, this paper introduced the post management, role function, core competence and career development prospect of clinical research nurses in the process of carrying out clinical trial of lung cancer drugs in detail. In order to provide reference for more medical institutions to carry out related work, and promote the further development of clinical research nurses to standardization and specialization.

ABSTRACT

Periodontal diseases are inflammatory diseases caused by oral pathogens around the periodontal supporting tissues, leading to systemic and chronic inflammatory conditions. The continuous chronic systemic inflammation may be a trigger of neuroinflammation, which is the prominent feature of a variety of neurological disorders. It implies that there may be a causal link between periodontal diseases and neurological disorders. This article presents epidemiological and biological evidences that periodontal diseases can induce or exacerbate neurological disorders, including Alzheimer's disease, Parkinson's disease, multiple sclerosis and major depressive disorder, and analyzes the possible mechanisms. The importance of maintaining oral health as well as preventing and treating periodontal diseases are emphasized. At the same time, this may provide novel approaches to study the relationship between periodontal diseases and neurological disorders in the prevention and treatment strategies of neurological disorders.

ABSTRACT

With the aging process of population in the society, the prevalence of cardiovascular diseases (CVD) in China is increasing continuously and the number of dental patients with CVD is increasing gradually too. Due to the lack of guidelines for dental patients with CVD in our country, how to implement standardized preoperative evaluation and perioperative risk prevention remains a problem to be solved for dentists at present. The present expert consensus was reached by combining the clinical experiences of the expert group of the Fifth General Dentistry Special Committee, Chinese Stomatological Association and respiratory and cardiology experts in diagnosis and treatment for CVD patients, and by systematically summarizing the relevant international guidelines and literature regarding the relationship between CVD and oral diseases and the diagnosis and treatment of dental patients with heart failure, hypertension and antithrombotic therapy. The consensus aims to provide, for the dental clinicians, the criteria on diagnosis and treatment of CVD in dental patients in China so as to reduce the risk and complications, and finally to improve the treatment levels of dental patients with CVD in China.

ABSTRACT

Background@#A patient’s infectivity is determined by the presence of the virus in different body fluids, secretions, and excreta. The persistence and clearance of viral RNA from different specimens of patients with 2019 novel coronavirus disease (COVID-19) remain unclear. This study analyzed the clearance time and factors influencing 2019 novel coronavirus (2019-nCoV) RNA in different samples from patients with COVID-19, providing further evidence to improve the management of patients during convalescence.@*Methods@#The clinical data and laboratory test results of convalescent patients with COVID-19 who were admitted to from January 20, 2020 to February 10, 2020 were collected retrospectively. The reverse transcription polymerase chain reaction (RT-PCR) results for patients’ oropharyngeal swab, stool, urine, and serum samples were collected and analyzed. Convalescent patients refer to recovered non-febrile patients without respiratory symptoms who had two successive (minimum 24 h sampling interval) negative RT-PCR results for viral RNA from oropharyngeal swabs. The effects of cluster of differentiation 4 (CD4)+ T lymphocytes, inflammatory indicators, and glucocorticoid treatment on viral nucleic acid clearance were analyzed.@*Results@#In the 292 confirmed cases, 66 patients recovered after treatment and were included in our study. In total, 28 (42.4%) women and 38 men (57.6%) with a median age of 44.0 (34.0–62.0) years were analyzed. After in-hospital treatment, patients’ inflammatory indicators decreased with improved clinical condition. The median time from the onset of symptoms to first negative RT-PCR results for oropharyngeal swabs in convalescent patients was 9.5 (6.0–11.0) days. By February 10, 2020, 11 convalescent patients (16.7%) still tested positive for viral RNA from stool specimens and the other 55 patients’ stool specimens were negative for 2019-nCoV following a median duration of 11.0 (9.0–16.0) days after symptom onset. Among these 55 patients, 43 had a longer duration until stool specimens were negative for viral RNA than for throat swabs, with a median delay of 2.0 (1.0–4.0) days. Results for only four (6.9%) urine samples were positive for viral nucleic acid out of 58 cases; viral RNA was still present in three patients’ urine specimens after throat swabs were negative. Using a multiple linear regression model (F=2.669, P=0.044, and adjusted R2=0.122), the analysis showed that the CD4+ T lymphocyte count may help predict the duration of viral RNA detection in patients’ stools (t=-2.699, P=0.010). The duration of viral RNA detection from oropharyngeal swabs and fecal samples in the glucocorticoid treatment group was longer than that in the non-glucocorticoid treatment group (15 days vs 8.0 days, respectively; t=2.550, P=0.013) and the duration of viral RNA detection in fecal samples in the glucocorticoid treatment group was longer than that in the non-glucocorticoid treatment group (20 days vs 11 days, respectively; t=4.631, P <0.001). There was no statistically significant difference in inflammatory indicators between patients with positive fecal viral RNA test results and those with negative results (P >0.05).@*Conclusions@#In brief, as the clearance of viral RNA in patients’ stools was delayed compared to that in oropharyngeal swabs, it is important to identify viral RNA in feces during convalescence. Because of the delayed clearance of viral RNA in the glucocorticoid treatment group, glucocorticoids are not recommended in the treatment of COVID-19, especially for mild disease. The duration of RNA detection may relate to host cell immunity.

ABSTRACT

Cardiac dysfunction (CD) combined with sepsis leads to increase in mortality in intensive care unit (ICU). Currently, the clinical treatment of CD with sepsis is the combination of delaying heart failure and anti-sepsis therapeutics. Mild therapeutic hypothermia (MTH) may decrease the body temperature to 32-35 ℃, improve symptom and decrease mortality in patients with CD and animal with sepsis. MTH has been used in animal models of heart failure and sepsis with pronounced outcomes and reduced mortality. However, it remains controversial if MTH can be used in treating patients with CD and sepsis due to its side effects, although the effectiveness of MTH on CD and sepsis has been testified. The present article reviews the application of MTH on animal researches, clinical use for treatment of patients with CD and sepsis, the effect and possible mechanisms of temperature on heart and sepsis, as well as the effect of MTH onto other organs and coagulation function.

ABSTRACT

OBJECTIVES: Although patients with grade I and II endometrioid endometrial adenocarcinoma (EEA) are considered with good prognosis, among them 15%–25% died in 5 years. It is still unknown whether integrating estrogen receptor (ER) and progesterone receptor (PR) into clinical risk stratification can help select high-risk patients with grade I–II EEA. This study was to investigate the prognostic value of ER and PR double negativity (ER/PR loss) in grade I–II EEA, and the association between ER/PR loss and The Cancer Genome Atlas (TCGA) classification. METHODS: ER and PR were assessed by immunohistochemistry on hysterectomy specimens of 903 patients with grade I–II EEA. ER and PR negativity were determined when < 1% tumor nuclei were stained. Gene expression data were obtained from the TCGA research network. RESULTS: Compared with ER or PR positive patients (n=868), patients with ER/PR loss (n=35) had deeper myometrial infiltration (p=0.012), severer FIGO stage (p=0.004), and higher rate of pelvic lymph node metastasis (p=0.020). In univariate analysis, ER/PR loss correlated with a shorter progression-free survival (PFS; hazard ratio [HR]=5.25; 95% confidence interval [CI]=2.21–12.52) and overall survival (OS; HR=7.59; 95% CI=2.55–22.60). In multivariate analysis, ER/PR loss independently predicted poor PFS (HR=3.77; 95% CI=1.60–10.14) and OS (HR=5.56; 95% CI=1.37–22.55) for all patients, and poor PFS for patients in stage IA (n=695; HR=5.54; 95% CI=1.28–23.89) and stage II–IV (n=129; HR=5.77; 95% CI=1.57–21.27). No association was found between ER/PR loss and TCGA classification. CONCLUSION: Integrating ER/PR evaluation into clinical risk stratification may improve prognosis for grade I–II EEA patients.

ABSTRACT

The implementation of knowledge management (KM) in hospitals affects efficiency and outcomes of hospitals.However,few studies explored the implementation of KM in China.Twenty-two questions were designed concerning KM implementation status in over 50 hospitals.In order to understand the KM level and attitude to KM of the hospital's managers,a random sampling survey was conducted among 138 managers from 50 different scales of hospitals in 15 provinces of China.The survey showed that overall level of KM implementation in Chinese hospitals was still low and differed among different scales of hospitals (P<0.05,or P<0.01).In all the hospitals investigated,63.8% did not implement KM yet,among which 46% even had not planned for that.49.8% of the hospitals investigated had no training program about KM ever and the main source of hospital staff to get knowledge was iuternet.It suggested that hospital managers should make much more efforts to get to know and understand theories on KM,so that hospital KM could be promoted more rapidly.

ABSTRACT

Glioblastoma is a common brain tumor and the overall survival rate of the patients is very low, so it is an effective way to develop the potential chemotherapy or adjuvant chemotherapy drugs in glioblastoma treatment. As a well-known antimalarial drug, artesunate(ARTs) has clear side effects, and recently it has been reported to have antitumor effects, but rarely reported in glioblastoma. Different concentrations of ARTs were used to treat the glioblastoma cells, and then the inhibitory effect of ARTs on glioblastoma proliferation was detected by MTT assay; Ki67 immunofluorescence assay was used to detect the proliferation of cells; Soft agar experiment was used to explain the clonal formation abilities ; Flow Cytometry was used to detect the cell cycle; and Western blot assay was used to determine the expression of key cell cycle protein. MTT assay results indicated that ARTs-treated glioblastoma cell A172, U251, U87 were significantly inhibited in a time-and-dose dependent manner as compared to the control group(DMSO treatment group). Soft agar experiment showed that ARTs could significantly reduce the clonal formation ability of glioblastoma. Furthermore, Flow cytometry analysis showed that ARTs could obviously increase the cell proportion in G₀/G₁ phase and reduce the cell proportion in S phase. Western blot results showed that the expressions of cell cycle-related proteins CDK2, CDK4, cyclin D1 and cyclin B1 were all obviously down-regulated. Above all, ARTs may inhibit the proliferation of glioblastoma cells by arresting cell cycle in G₀/G₁ phase through down-regulating the expression of CDK2, CDK4, cyclin D1, cyclin B1. These results may not only provide a novel method for rediscovering and reusing ARTs but also provide a new potential drug for treating glioblastoma.

ABSTRACT

OBJECTIVE: Our previous study showed that insulin resistance (IR) was related to endometrial hyperplasia as well as endometrial cancer. But the exact impact of IR on fertility-sparing treatment in endometrial hyperplasic disease is unclear. This study investigated how IR affects fertility-sparing treatment in endometrial atypical hyperplasia (EAH) patients. METHODS: The 151 EAH patients received fertility-sparing treatment were retrospectively investigated. All patients received high-dose progestin combined with hysteroscopy. Therapeutic effects were evaluated by hysteroscopy every 3 months during the treatment. RESULTS: The median age was 33.0 years old (range, 21–54 years old). Sixty-one patients (40.4%) were insulin resistant. Three patients were excluded from the analysis because they chose hysterectomy within 3 months after initiation of progestin treatment. The 141 out of 148 (95.3%) patients achieved complete response (CR). No difference was found in cumulative CR rate between those with or without IR (90.2% vs. 95.6%, p=0.320). IR significantly affected therapeutic duration to achieve CR (8.1±0.5 months with IR vs. 6.1±0.4 months without IR, p=0.004). Overweight (body mass index [BMI]≥25 kg/m2) was associated with higher risk of treatment failure (odds ratio=5.61; 95% confidence interval=1.11–28.35; p=0.040) and longer therapeutic duration to achieve CR (7.6±0.5 months vs. 6.3±0.4 months, p=0.019). EAH patients with both IR and overweight (IR+BMI+) had the longest therapeutic time compared with other patients (8.8±0.6 months vs. 5.6±0.7, 6.3±0.4, and 6.4±0.8 months for IR−BMI+, IR−BMI−, and IR+BMI−, respectively, p=0.006). CONCLUSION: IR and overweight were associated with longer therapeutic duration in EAH patients receiving progestin-based fertility-sparing treatment.

ABSTRACT

Objective: To establish an HPLC method for the simultaneous determination of 3 active components in compound he-mostatic capsules and investigate the content changes before and after 60Co-γ ray irradiation. Methods: An Agilent-C18column (250 mm×4. 6 mm, 5 μm) was adopted and the flow rate was 1. 0 ml·min-1. The mobile phase consisted of acetonitrile-0. 5% phosphor-ic acid solution (triethylamine was used to adjust pH to 6) with gradient elution, the detection wavelength was 254 nm (0-35 min) and 281 nm (35-55 min), and the column temperature was 35℃. The compound hemostatic capsules were irradiated at 5, 8 and 10 kGy, respectively, and the contents of the 3 active components in compound hemostatic capsules were compared before and after the radia-tion,and the t-test was applied to investigate the significance. Results: Typhaneoside,isorhamnetin-3-O-neohesperidin and tetrahydro-palmatine respectively within the concentration range of 0. 018-0. 11 mg·ml-1,0. 020-0. 120 mg·ml-1and 0. 011-0. 066 mg·ml-1 showed a good linear relationship with the peak area. The average recovery was 97. 7% , 98. 7% and 99. 3% with the RSD of 0. 9% , 0. 9% and 0. 5% , respectively (n=6). After the irradiation, the contents of the three active components in compound hemostatic capsules all showed changes. Under the dose of 8 kGy, the content changes of typhaneoside and isorhamnetin-3-O- neohesperidin showed no statistical significance (P>0. 05),and when the dose increased to 10 kGy,the content of tetrahydropalmatine exhibited sig-nificant difference (P<0. 05). Conclusion: The established determination method for compound hemostatic capsule shows such ad-vantages as high recovery, good repeatability, simple operation and promising separation, which can be used as a quality control meth-od for compound hemostatic capsules. The sterilization effect of 60Co-γ ray irradiation on compound hemostatic capsules is significant without notable changes in the active components. When the irradiation dose is equal to or below 5 kGy,the change of each component is not obvious,which can provide reference for the radiation sterilization of compound hemostatic capsules.
