Objective To observe the clinical efficacy of modified Sanzi Yangqin Decoction for the treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Totally 80 cases of OSAHS patients were randomly divided into treatment group and control group, with 40 cases in each group. Both groups received intervention of diet and life. The control group was given vitamin C, 100 mg each time, 3 times a day orally. Treatment group was given modified Sanzi Yangqin Decoction, 1 dosage per day, twice a day, orally, for 14 d. The scores of TCM symptoms, sleep apnea (AHI), lowest oxygen saturation (LSaO2) and longest apnea were observed before and after treatment. Results The overall effective rate of TCM syndrome was 90% (36/40) in the treatment group and 65% (26/40) in the control group, with statistical significance (P<0.05). Compared with before treatment, there was statistical significance in the scores of TCM symptoms, AHI, LSaO2, and longest apnea (P<0.05,P<0.01). After the treatment, compared with the control group, there was statistical significance in the scores of TCM symptoms, AHI, and LSaO2 in the treatment group (P<0.05,P<0.01). Conclusion Modified Sanzi Yangqin Decoction can effectively treat OSAHS and improve the life quality of patients.

OBJECTIVETo investigate the dynamics and clinical significance of serum hepatitis B virus (HBV) DNA levels during the terminal phase of acute-on-chronic liver failure (ACLF) with different hepatitis B e antigen (HBeAg) status.

METHODSOne-hundred-and-seven patients with terminal ACLF were tested for HBeAg status by electrochemiluminescence immunoassay and serum HBV DNA levels by real-time PCR at three chronological time ranges, representing increasing severity of disease phases prior to death (day 0): 29-56 d, 15-28 d, and 0-14 d.

RESULTSIn the 37 HBeAg(+) patients, HBV DNA levels at above-mentioned phases were 6.10+/-1.63, 5.61+/-1.50, and 5.29+/-1.96 log10 copies/mL. In the 70 anti-HBe(+) patients, HBV DNA levels were 4.63+/-1.82, 5.81+/-1.78, and 4.93+/-1.73 log10 copies/mL. Phase to phase comparisons revealed that the HBV DNA level in the HBeAg(+) group was significantly higher than that in the anti-HBe(+) group at 29-56 d (P less than 0.05), and that 15-28 d and 0-14 d were not significantly different (P more than 0.05). Intragroup comparisons of phases revealed no significant differences in the HBeAg(+) group (P more than 0.05), but a significant difference between 15-28 d and 0-14 d (P less than 0.05) for the anti-HBe(+) group.

CONCLUSIONSerum levels of HBV DNA in patients with HBeAg positivity are higher than those in patients with anti-HBe positivity as the disease phase of ACLF nears fatality. Following the deterioration to liver failure, the HBV DNA load in HBeAg(+) patients remains stable while that in anti-HBe(+) patients decreases.

BACKGROUNDThe most critical mechanism governing drug resistance in Candida albicans (C. albicans) involves efflux pumps, the functionality of which largely depends on energy metabolism. Alcohol dehydrogenase I (ADH1) plays an important role in intracellular energy metabolism. The aim of this study was to explore the relationship between ADH1 and drug resistance in C. albicans.

METHODSTwenty clinical C. albicans samples isolated from individual patients diagnosed with vulvovaginal candidiasis, and two C. albicans strains obtained from a single parental source (the fuconazole (FLC)-sensitive strain CA-1S and the FLC-resistant strain CA-16(R)) were included in our study. In accordance with the Clinical and Laboratory Standards Institute (CLSI) M27-A3 guidelines, we used the microdilution method to examine the FLC minimum inhibitory concentrations (MICs) and real-time reverse transcription polymerase chain reaction (RT-PCR) to measure the mRNA expression levels of ADH1 and the azole resistance genes CDR1, CDR2, MDR1, FLU1 and ERG11 in all the isolates.

RESULTSA highly significant positive correlation between the mRNA levels of ADH1 and the MICs (rs = 0.921, P = 0.000), as well as positive correlations between the mRNA level of ADH1 and those of CDR1, CDR2 and FLU1 (rs of 0.704, 0.772 and 0.779, respectively, P < 0.01), were observed in the 20 clinical C. albicans samples. The relative expression of ADH1 was upregulated 10.63- to 17.61-fold in all of the drug-resistant isolates. No correlations were found between the mRNA levels of ADH1 and those of MDR1 or ERG11 (P > 0.05). The mRNA levels of the examined drug resistance genes were higher in the CA-16(R) strain than in CA-1(S), and the mRNA levels of ADH1 in CA-16(R) were 11.64-fold higher than those in CA-1(S) (P < 0.05).

CONCLUSIONSThese results suggest that high levels of ADH1 transcription are implicated in FLC resistance in C. albicans and that the mRNA expression levels of ADH1 are positively correlated with those of CDR1, CDR2 and FLU1.

OBJECTIVETo investigate the clinical epidemiological characteristics of neonatal respiratory failure in 1,108 neonates, and to provide a reference for improvement in clinical treatment and multicenter clinical studies.

METHODSThe clinical data of 1,108 neonates with respiratory failure were collected with questionnaires, and statistical analysis was performed for the epidemiological indices including primary diseases, clinical therapeutic methods, treatment outcome, and fatality.

RESULTSIn all the neonates with respiratory failure, the median gestational age was 37 weeks+1 day, the median birth weight was 2,600 g, the median age in days on admission to neonatal intensive care unit was 0.71 days (17 hours), and the boy/girl ratio was 3.1:1. The major primary diseases were respiratory distress syndrome (30.51%), pulmonary infection/sepsis (23.55%), and wet lung (13.18%). Of all the neonates, 48.64% received nasal continuous positive airway pressure (nCPAP), 12.81% received high-frequency oscillatory ventilation, 13.45% received pulmonary surfactant, and 8.66% received nitric oxide inhalation therapy. The fatality was 24.19%.

CONCLUSIONSThe major primary disease for neonatal respiratory failure is respiratory distress syndrome. Pulmonary surfactant, nCPAP, high-frequency oscillatory ventilation, and nitric oxide inhalation therapy are major therapeutic methods for neonatal respiratory failure, but neonatal respiratory failure still has a high fatality.

Objective To understand the epidemiological character of malaria in Haidian District of Beijing from 2005 to 2017. Methods The epidemiological data of malaria was collected from the infectious disease reporting system of medical institutions at various levels in Haidian District of Beijing from 2005 to 2017, and the epidemiological methods was used to analyze the distribution of malaria in population, time and region. Results From 2005 to 2017, 111 malaria cases were reported in Haidian District of Beijing, the annual average incidence rate was 0.26/100 000 and one death case was reported in 2014. Among the four reported types of falciparum malaria, vivax malaria, three-day malaria and untyped malaria, the most common falciparum malaria (54.5%, 60/111), no mixed infection; The peak incidence was concentrated in the summer and autumn of June-September (52.0%, 58/111); the cases were mainly occurred in young adults aged from 20 to 59(93.7%,104/111), and the incidence of males was higher than that of females ( 2=52.9, P<0.001); Cadres were the main ward population (33.3%, 33/111). Malaria cases were reported in 26 streets and towns in Haidian District. 81 cases were imported from abroad, accounting for 71.4% of the total cases, of which 74 (91.36%) were originated from Africa. Conclusions In the past 13 years, the incidence of malaria was sporadic, mainly in imported cases. The monitoring of malaria should be strengthened by entry and exit to prevent the second-generation cases of malaria.

Hepatitis E virus (HEV) sequences including four major genotypes representative strains available in GenBank were aligned with the DNAMAN software. The highly conserved internal region of ORF2 was then subjected to design primers and a probe. Furthermore, a 0.3 kb fragment of HEV ORF2 containing the amplification region was transcribed in vitro to synthese cRNA standard and a universal real-time TaqMan PCR assay was optimized and developed to detect and quantify main genotypes RNA of HEV. The specificity and reliability of the real-time RT-PCR was confirmed by testing genotype I HEV, genotype IV HEV and clinical samples. The detection limit of real-time RT-PCR was found 2.0 x 10(1) copies per reaction using in vitro transcribed cRNA. Compared with nested RT-PCR in diagnosis of HEV, the real-time RT-PCR developed was 10 to 100-fold more sensitive than the nested RT-PCR. The detection results from 54 clinical specimens indicated real-time RT-PCR was a rapid, sensitive and reproducible diagnostic method for HEV. This assay will be useful as an early and rapid diagnostic assay for HEV.

OBJECTIVESTo study the etiology, clinical and pathologic characteristics of periductal mastitis with fistula and estimate the effect of anti-mycobacterial agents for periductal mastitis with fistula.

METHODSTotally 27 patients of periductal mastitis with fistula received anti-mycobacteria drugs therapy from December 2008 to September 2011 were analyzed retrospectively. All of the patients were female. The mean age at onset was 28 years (range 15 to 40 years old). The main clinical manifestation of the 27 patients was breast fistula, including 21 patients with single fistula and 6 patients with multiple fistula. Three patients manifested with pure fistula, 14 patients with both fistula and lump, 10 patients with fistula, lump and abscess. The samples including pus or tissues of all patients were underwent bacteria culture and all patients core needle biopsy. All patients were given primary anti-mycobacteria drugs therapy, parts of patients received surgery based on the evaluation of medical treatment.

RESULTSThe common bacteria culture of all patients failed to demonstrate any causative microorganism. Four cases were selected randomly to undergo PCR of mycobacteria, only one case was identified as Massiliense in bacteria culture of mycobacteria. Twenty-seven patients with periductal mastitis with fistula were treated with anti-mycobacterial agents (isoniazid, rifampicin and ethambutol or pyrazinamide of triple oral drugs) for 1 to 3 months, the fistula of all 27 patients were closed well. Sixteen patients were treated with the agents only and cured. Eleven patients received surgical treatment after treated with the medical agents. None of the patients were given mastectomy. All patients had no reccurence until now.

CONCLUSIONSThe periductal mastitis with fistula has a closely relationship with the infection of nontuberculosis mycobacteria. Those patients could be treated with triple anti-mycobacterial agents and could also avoided mastectomy.

OBJECTIVE: To establish a secondary hemophagocytic lymphohistiocytosis(HLH) mouse model, and to investigate the effect of ruxolitinib on the disease manifestation of model mice. METHODS: Wild type C57BL/6 mice were randomly divided into 4 groups: two groups of mice were intraperitoneally injected with CpG oligodeoxynucleotide 1826 (CpG-ODN1826) every other day to induce HLH, and other two groups were control groups. One group of the CpG-ODN1826 groups and one of the control groups were given ruxolitinib, and other two groups were given the same amount of PBS. Blood samples, serum ferritin and hepatic/spleen weights of experimental mice were detected and serum cytokine levels were measured by ELISA. RESULTS: Compared with the control groups, the levels of white blood cells, hemoglobin and platelets in the CpG-ODN1826 groups were significantly lower (P＜0.05); and liver/body weight, spleen/body weight, serum ferritin, sCD25, IL-10, IL-1β, IFN-Ƴ, IL-12p70, GM-CSF, TNF-α and IL-18 levels significantly increased (P＜0.05). There was no significant difference in the levels of IL-2, IL-4, IL-5, IL-6, IL-22, IL-13, IL-27 and IL-23 between the two groups (P＞0.05). The spleen in CpG group had disordered internal structure, expanding red pulp and hyperplastic nucleated cells. The liver had severe perivascular inflammations. The spleen/weight of the ruxolitinib-treated mice in the CpG-ODN1826 group was significantly smaller than that of the unapplied ruxolitinib (P＜0.05). CONCLUSION The CpG-ODN1826 can induce secondary HLH symptoms in wild type C57BL/6 mice. Ruxolitinib can alleviate the symptoms of splenomegaly in HLH model mice.

Objective: To evaluate the predictive value of the proportion of hibernating myocardium (HM) in total perfusion defect (TPD) on reverse left ventricle remodeling (RR) after coronary artery bypass graft (CABG) in patients with heart failure with reduced ejection fraction (HFrEF) by ^99mTc-methoxyisobutylisonitrile (MIBI) single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) combined with ¹⁸F-flurodeoxyglucose (FDG) gated myocardial imaging positron emission computed tomography (PET). Methods: Inpatients diagnosed with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2016 to January 2022 were prospectively recruited. MPI combined with ¹⁸F-FDG gated PET was performed before surgery for viability assessment and the patients received follow-up MPI and ¹⁸F-FDG gated PET at different stages (3-12 months) after surgery. Δ indicated changes (post-pre). Left ventricular end-systolic volume (ESV) reduced at least 10% was defined as RR, patients were divided into reverse remodeling (RR+) group and the non-reverse group (RR-). Binary logistic regression analysis was used to identify predictors of RR. Receiver operating characteristic (ROC) curve analysis was performed and the area under the curve (AUC) was calculated to assess the cut-off value for predicting RR. Additionally, we retrospectively enrolled inpatients with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2021 to January 2022 as the validation group, who underwent MPI and ¹⁸F-FDG gated PET before surgery. Echocardiography was performed before CABG and after CABG (3-12 months). In the validation group, the reliability of obtaining the cut-off value for the ROC curve was verified. Results: A total of 28 patients with HFrEF (26 males; age (56.9±8.7) years) were included in the prospective cohort. HM/TPD was significantly higher in the RR+ group than in the RR- group ((51.8%±17.9%) vs. (35.7%±13.9%), P=0.016). Binary logistic regression analysis revealed that HM/TPD was an independent predictor of RR (Odds ratio=1.073, 95% Confidence interval: 1.005-1.145, P=0.035). ROC curve analysis revealed that HM/TPD=38.3% yielded the highest sensitivity, specificity, and accuracy (all 75%) for predicting RR and the AUC was 0.786 (P=0.011). Meanwhile, a total of 100 patients with HFrEF (90 males; age (59.7±9.6) years) were included in the validation group. In the validation group, HM/TPD=38.3% predicted RR in HFrEF patients after CABG with the highest sensitivity, specificity and accuracy (82%, 60% and 73% respectively). Compared with the HFrEF patients in the HM/TPD<38.3% group (n=36), RR and cardiac function improved more significantly in the HM/TPD≥38.3% group (n=64) (all P<0.05). Conclusions: Preoperative HM/TPD ratio is an independent factor for predicting RR in patients with HFrEF after CABG, and HM/TPD≥38.3% can accurately predict RR and the improvement of cardiac function after CABG.
