Objective: The objective of this study was to present the real-world patients’ portrait, and the results of niraparib treatment in China. Methods: This study included 142 patients treated with niraparib from 8 hospitals in China between December 2018 and September 2021. Patients’ characteristics were summarized. The efficacy and safety in first-line maintenance (1L-M), platinum-sensitive recurrence maintenance (PSR-M), and treatment for ovarian cancer were evaluated. Survival outcomes and the factors influencing progression-free survival (PFS) were estimated. Results: The 93 patients received Niraparib as 1L-M, 31 as PSR-M and 18 as salvage. BRCA status was wild type or unknown in 87.3% of patients. With a median follow-up time of 8.7 months, the median PFS (mPFS) for 1L-M has not yet been reached, and the mPFS for PSR-M and salvage therapy was 10.5 and 5.7 months, respectively. Responses to last chemotherapy and cancer antigen 125 value before taking niraparib were 2 important factors affecting PFS among 1L and PSR patients. The 12.7% (18/142) of patients experienced grade ≥3 hematologic adverse events and 23.2% experienced dose adjustment. It was noteworthy that when the interval of chemotherapy and niraparib <21 days, the incidence of grade ≥3 adverse events increased significantly (p=0.0355). Conclusion Generally, niraparib was effective and well tolerated, which was consistent with the results of prospective trials. However, in real world, it was more inclined to use niraparib in late-line treatment without genetic testing.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

OBJECTIVE To investigate the effects of total flavonoids of bugloss(TFB)on left ventricular (LV)remodeling after myocardial infarction(MI),LV size and function was compared in mice subjected to left anterior descending coronary artery ligation. METHODS 28 d after MI, the infarcted fraction of the LV and LV mass, systolic and diastolic function were measured. Capillary density and myocyte width in the nonischemic portion of the LV were also determined.RESULTS 28 d after MI,both groups had dilated LVs with decreased fractional shortening and lower ejection fractions. Although the infarcted size of the LV was similar in both groups,LV end-diastolic internal diameter,end-diastolic volume,and mass were lower, but fractional shortening, ejection fraction, and the maximum rate of developed LV pressure(dp/dtmax)were greater in TFB treated mice than in control mice.Impairment of diastolic func-tion, as measured by the time constant of isovolumic relaxation (t) and the maximum rate of LV pres-sure decay(dp/dtmin),was more marked in control mice than in TFB treated mice.Mortality after MI was greater in control mice than in TFB treated mice.In control mice,capillary density and myocyte width in the nonischemic portion of the LV did not differ before and 28 days after MI, whereas in TFB treated mice, capillary density increased and myocyte width declined after MI. CONCLUSION These results suggest that the presence of TFB limits LV dysfunction and remodeling in a murine model of MI in part by decreasing myocyte hypertrophy in the remote myocardium.

·AIM: To observe the clinical efficacy of fumigation treatment of traditional Chinese medicine(Four Yellow Qing Ling Water) for dry eye, and to provide the reference for clinical treatment of dry eye. · METHODS: Totally 82 patients (164 eyes) were randomly divided into two groups from June 2016 to December 2016 in Ophthalmology Department of our hospital. The patients in control group were given artificial tears;the patients in the observation group were given artificial tears and fumigation treatment of traditional Chinese(Four Yellow Qing Ling Water) once a day. After treatment for 14d, the SchirmerⅠtest (SⅠt), break-up time (BUT), cornea fluorescein staining (FL) and clinical efficacy of two groups were compared. ·RESULTS:The efficiency rate of observation group was significantly better than the control group (87. 8% vs 70.7%,P<0.5). The SⅠt and BUT in the observation group were significantly higher than those in the control group (8.43 ± 2.51mm/5min vs 6.38 ± 2.52mm/5min, P<0.05;8.60±2.47s vs 6.35±2.29s, P<0.05); the FL in the observation group (0.84 ± 0.75 vs 1.26 ± 0.84, P<0.05) significantly lower than those in the control group. ·CONCLUSION: The fumigation treatment of traditional Chinese medicine (Four Yellow Qing Ling Water) combined with artificial tears for dry eyes can improve the clinical symptoms of dry eye syndrome.

OBJECTIVETo investigate the significance of flexible bronchoscopy in children with respiratory diseases.

METHODSA retrospective analysis was performed for the clinical data of 80 children who were hospitalized due to respiratory diseases (including severe pneumonia, Mycoplasma pneumoniae pneumonia with atelectasis/lung consolidation/local emphysema, protracted pneumonia, coughing and wheezing of unknown cause, chronic cough of unknown cause, and laryngeal stridor) and who underwent flexible bronchoscopy/alveolar lavage.

RESULTSBronchoscopy found that all the 80 children had endobronchial inflammation, among whom 28 children had severe airway obstruction by secretion. Twenty-four children had congenital airway dysplasia besides endobronchial inflammation, and three children had bronchial foreign bodies. In the children with coughing and wheezing of unknown cause and laryngeal stridor, some had congenital airway dysplasia or bronchial foreign bodies. Among the 27 children with Mycoplasma pneumoniae pneumonia, 26 had severe airway obstruction/embolization by secretion; 25 children (93%) underwent chest imaging again at 2 weeks after alveolar lavage, and the results showed complete or partial lung recruitment. Among the 80 children who underwent bronchoscopy, 3 had severe hypoxemia during surgery, 1 had epistaxis, 1 had minor bleeding during alveolar lavage, 3 had transient bronchospasm, and 5 had postoperative fever; these children were all improved after symptomatic treatment.

CONCLUSIONSFlexible bronchoscopy is safe and reliable in children with respiratory diseases. Early alveolar lavage under a flexible bronchoscope is recommended for children with severe/refractory Mycoplasma pneumoniae pneumonia to improve prognosis. Flexible bronchoscopy is recommended for children with recurrent coughing and wheezing and persistent laryngeal stridor, in order to directly observe the throat and airway under an endoscope.

Objective To investigate the relationship between the levels of plasma adrenaline and norepinephrine and gene polymorphism of β1 adrenergic receptor G1165C in children with enterovirus 71 (EV71) infection in hand foot and mouth disease (HFMD). Methods The polymerase chain reaction (PCR) was used to detect the expression of gene polymorphism of β1 adrenergic receptor G1165C in vitro. The levels of plasma adrenaline and norepinephrine were measured by enzyme-linked immunosorbent assay (ELISA). Results The plasma norepinephrine level of severe group was significantly higher than the mild group in children with EV71 infection in HFMD (P < 0.05); however, the levels of plasma adrenaline in two groups had no statistical differences (P > 0.05); There was no significant difference in the distribution of β1 adrenergic receptor G1165C genotype and allele between EV71 infection group and healthy control group (P > 0.05). Further analysis of EV71 infection group by dividing it into mild and severe groups showed that there was no significant difference in the distribution of genotype and allele between these two groups as well (P > 0.05). There was no significant difference in the levels of epinephrine and norepinephrine in different genotypes of EV71 infection group (P > 0.05), and in the levels of plasma epinephrine and norepinephrine in the mild and severe groups (P > 0.05). Conclusions As the disease gets worse, the plasma norepinephrine level has a rising trend in children with EV71 infection in HFMD, which is an important indicator to evaluate the progress of the disease. However, the gene polymorphism of β1 adrenergic receptor G1165C have no significant correlation, not only with the susceptibility and severity of EV71 infection in hand, foot and mouth disease, but also with the levels of catecholamine.

Background: Esophageal cancer is associated with substantial disease burden in China, and data on the economic burden are fundamental for setting priorities in cancer interventions. The medical expenditure for the diagnosis and treatment of esophageal cancer in China has not been fully quantified. This study aimed to examine the medical expenditure of Chinese patients with esophageal cancer and the associated trends. Methods: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 37 hospitals in 13 provinces/municipalities across China as a part of the Cancer Screening Program of Urban China. For each esophageal cancer patient diagnosed between 2002 and 2011, clinical information and expense data were extracted by using structured questionnaires. All expense data were reported in Chinese Yuan (CNY; 1 CNY= 0.155 USD) based on the 2011 value and inflated using the year-specific health care consumer price index for China. Results: A total of 14,967 esophageal cancer patients were included in the analysis. It was estimated that the overall average expenditure per patient was 38,666 CNY, and an average annual increase of 6.27％ was observed from 2002 (25,111 CNY) to 2011 (46,124 CNY). The average expenditures were 34,460 CNY for stage Ⅰ, 39,302 CNY for stage Ⅱ, 40,353 CNY for stage Ⅲ, and 37,432 CNY for stage IV diseases (P < 0.01). The expenditure also differed by the therapy type, which was 38,492 CNY for surgery, 27,933 CNY for radiotherapy, and 27,805 CNY for chemotherapy (P < 0.05). Drugs contributed to 45.02％ of the overall expenditure. Conclusions: These conservative estimates suggested that medical expenditures for esophageal cancer in China substantially increased in the last 10 years, treatment for early-stage esophageal cancer costs less than that for advanced cases, and spending on drugs continued to account for a considerable proportion of the overall expenditure.

In this study, ecological factors, occurrence records, the essential oil components content were used to predict the potential geographical distribution and quality division of Mentha haplocalyx in China based on the MaxEnt modeling and geographic information system(GIS). The AUC of ROC curve was above 0.950,indicating that the predictive results with the maximum model were highly precise. The results showed that the main environmental factors determining the potential distribution were annual average precipitation (the contribution rate, 45.87%), mean temperature of wettest quarter (11.92%), mean temperature of warmest quarter (7.84%), average monthly precipitation of May (6.80%), standard deviation of seasonal temperature variation (4.42%), mean temperature of the coldest quarter (3.47%) and altitude (2.92%). The environmental variables in the highly potential areas were determined as annual average precipitation around [530,1 465] mm, mean temperature of wettest quarter around [24.5,29] ℃, mean temperature of the warmest quarter around [25.5,29] ℃, average monthly precipitation of May around [67,133] mm, standard deviation of temperature seasonal change around [8 333,9 643], mean temperature of the coldest quarter around [1.7,8.3] ℃ and the altitude around [0,165] mm. The best quality distribution of M. haplocalyx was mainly located in Jiangsu, Anhui, Shandong, Zhejiang and Heilongjiang. The zoning results basically coincide with the actual situation. The quality division of M. haplocalyx can be used for providing a scientific basis for selection of artificial planting base and guidance of its production.

This study aims to investigate the function of two SNPs (rs8904C > T and rs696G >A) in 3' untranslated region (3'UTR) of NFKBIA gene by constructing luciferase reporter gene. A patient's genomic DNA with rs8904 CC and rs696 GA genotype was used as the PCR template. Full-length 3'UTR of NFKBIA gene was amplified by different primers. After sequencing validation, these fragments were inserted to the luciferase reporter vector, pGL3-promoter to construct recombinant plasmids containing four kinds of haplotypes, pGL3-rs8904C/rs696G, pGL3-rs8904C/rs696A, pGL3-rs8904T/rs696G and pGL3-rs8904T/rs696A. Then these plasmids were transfected into LS174T cells and the luciferase activity was detected. Compared with pGL3-vector transfected cells (negative control), the luciferase activity of the four kinds of recombinant plasmids was significantly decreased (P < 0.001). For rs696G > A, the luciferase activity of the recombinant plasmids containing A allele (pGL3-rs8904C/rs696A and pGL3-rs8904T/rs696A) was about 45.1% (P < 0.05) and 56.1% (P < 0.001) lower than those containing G allele (pGL3-rs8904C/rs696G and pGL3-rs8904T/rs696G), respectively. For rs8904C > T, there were no significant differences in the luciferase activity between the recombinant plasmids containing T allele and those with C allele. Together, the luciferase reporter gene vectors containing SNPs in NFKBIA gene 3'UTR were constructed successfully and rs696G > A could decrease the luciferase activity while rs8904C >T didn't have much effect on the luciferase activity.
