ABSTRACT

This study intended to explore the effect and mechanism of total flavonoids of Drynariae Rhizoma in improving scopola-mine-induced learning and memory impairments in model mice. Ninety four-month-old Kunming(KM) mice were randomly divided into six groups. The ones in the model group and blank group were treated with intragastric administration of normal saline, while those in the medication groups separately received the total flavonoids of Drynariae Rhizoma, Kangnaoshuai Capsules, donepezil, as well as total flavonoids of Rhizoma Drynariae plus estrogen receptor(ER) blocker by gavage. The mouse model of learning and memory impairments was established via intraperitoneal injection of scopolamine. Following the measurement of mouse learning and memory abilities in Morris water maze test, the hippocampal ERβ expression was detected by immunohistochemistry, and the expression levels of ERβ and phosphorylated p38(p-p38) in the hippocampus and B-cell lymphoma 2(Bcl-2), Bcl-2-associated death promoter(Bad), and cysteinyl aspartate-specific protease-3(caspase-3) in the apoptotic system were assayed by Western blot. The contents of malondia-ldehyde(MDA), superoxide dismutase(SOD), and nitric oxide(NO) in the hippocampus were then determined using corresponding kits. Compared with the control group, the model group exhibited significantly prolonged incubation period, reduced frequency of cros-sing the platform, shortened residence time in the target quadrant, lowered ERβ, Bcl-2 and SOD activity in the hippocampus, and increased p-p38/p38, Bad, caspase-3, MDA, and NO. Compared with the model group, the total flavonoids of Rhizoma Drynariae increased the expression of ERβ and SOD in the hippocampus, down-regulated the expression of neuronal pro-apoptotic proteins, up-re-gulated the expression of anti-apoptotic proteins, and reduced p-p38/p38, MDA, and NO. The effects of total flavonoids of Drynariae Rhizoma on the above indexes were reversed by ER blocker. It has been proved that the total flavonoids of Drynariae Rhizoma obviously alleviate scopolamine-induced learning and memory impairments in mice, which may be achieved by regulating the neuronal apoptotic system and oxidative stress via the ER-p38 mitogen-activated protein kinase(ER-p38 MAPK) signaling pathway.

ABSTRACT

In the past 37 years, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has undergone various major transmission routes in China, with the world most complex co-circulating HIV-1 subtypes, even the prevalence is still low. In response to the first epidemic outbreak of HIV in injecting drug users and the second one by illegal commercial blood collection, China issued the Anti-Drug Law and launched the Blood Donation Act and nationwide nucleic acid testing, which has avoided 98,232 to 211,200 estimated infections and almost ended the blood product-related infection. China has been providing free antiretroviral therapy (ART) since 2003, which covered >80% of the identified patients and achieved a viral suppression rate of 91%. To bend the curve of increasing the disease burden of HIV and finally end the epidemic, China should consider constraining HIV spread through sexual transmission, narrowing the gaps in identifying HIV cases, and the long-term effectiveness and safety of ART in the future.

ABSTRACT

Objective:To study the willingness of the medical staff of tertiary hospitals to be dispatched to work for a long time at the district hospitals under the " municipal trusteeship of district-ownership hospitals" mode, and explore the key factors that affect their long-term willingness, for references of optimizing the incentive system of the model.Methods:A questionnaire was designed as guided by the two-factor theory. In May 2019, a typical sample survey was made to investigate 103 medical staff of two tertiary hospitals in Beijing on their willingness to be dispatched to hospitals of district ownership. The survey covered such aspects as their basic personal information, hygiene factors(family responsibility, interpersonal connections expansion, mobilization and encouragement of leaders, etc.), and incentive factors(personal career development, greater potential giving play to their own talents, self-achievement, etc.). Descriptive analysis and univariate hypothesis testing were used to compare the differences of the dispatch willingness of staff of different characteristics. Meanwhile, an ordinal multinomial logistic regression model was built to analyze the influence factors of long-term dispatch willingness of these staff along with individual in-depth interviews.Results:The medical staff when they were dispatched to work at the entrusted hospitals for a long time, were concerned mostly with top six factors. These factors refered to a reasonable incentive(rewards)mechanism, family responsibility, colleague evaluation of the entrusted hospital, interpersonal connections expansion, personal career development, and potential unlocking. Those staff with dispatch experience had higher willingness to be dispatched than those without( P <0.05). The former saw higher of their personal career development resulting from the dispatch(3.91 points), while the latter saw higher their post-dispatch salary incentive mechanism(3.95 points). Compared with common medical staff, medium and high level management staff were more willing to be dispatched for a long time( H=14.536, P<0.001). Leadership mobilization in hygiene factors and personal career development in incentives factors were the key drivers for the long-term willingness of medical staff to be dispatched( P<0.05). Conclusions:The willingness of medical staff to be dispatched for a long time needs to be strengthened in the " municipal trusteeship of district-ownership hospitals" mode. Managers of the district-ownership hospitals should take into full consideration, the needs of different categories and levels of medical staff dispatched, guarantee the remuneration and performance pay of these staff, and enable their career track planning, hence mobilizing their incentives, and increase their willingness to work at such hospitals for a long time.

ABSTRACT

With the full implementation of the separation policy of medicine in China, the circulation of drugs in hospitals no longer produces direct economic value, but turns into the operating cost in the process of providing medical services. The research on the cost calculation of hospital pharmaceutical service can not only help the hospital to strengthen the internal cost management, but also provide the basis for the government policy compensation. This paper constructed a model of pharmaceutical service cost calculation based on job analysis, and produced basic pharmaceutical and advanced pharmaceutical service cost based on the data of a sample hospital.

ABSTRACT

Objective:To dynamically observe the effect of N-acetylserotonin (NAS) on the expression of tumor necrosis factor-α (TNF-α) protein in retina of retinal ischemia reperfusion injury (RIRI) rats, and to explore the mechanism.Methods:By using random number table method, 90 healthy male Sprague-Dawley rats were divided into sham operation group ( n=10), RIRI group ( n=40), and NAS group ( n=40). The right eye was as the experimental eye. In the RIRI group and NAS group, the anterior chamber high intraocular pressure method was used to establish the RIRI model. In the NAS group, 10 mg/kg NAS was injected intraperitoneally before modeling and 30 minutes after modeling. At 6, 12, 24, 72 h after modeling, hematoxylin-eosin staining was used to observe the pathological changes of the retina, and the retinal ganglion cells (RGC) were counted. Each group was detected by immunohistochemical staining and Western blot about the relative expression of TNF-α, nuclear factor E2-related factor 2 (Nrf2), and heme oxygenase-1 (HO-1) protein in the rat retina. Oneway analysis of variance was used for differences between groups. The general linear regression method was used to analyze the correlation between the relative expression changes of TNF-α protein and the changes of Nrf2 and HO-1 protein expression after NAS intervention. Results:Optical microscope observation revealed that the retinal edema of rats in the RIRI group was observed at 6, 12, and 24 h after modeling; the thickness of the retina in the NAS group was significantly thinner than that in the RIRI group, and the difference was statistically significant ( F=9.645, 477.150, 2.432; P<0.01). At 6, 12, 24, and 72 h after modeling, the retinal RGC counts in the NAS group were significantly higher than those in the RIRI group, and the difference was statistically significant ( F=12.225, 12.848, 117.655, 306.394; P<0.05). The results of immunohistochemical staining and Western blot showed that 6 h after modeling, the relative expression of TNF-α protein in the retina of the RIRI group increased significantly compared with that in the sham operation group, reaching a higher level at 12 h, and decreased at 24 and 72 h. But all were significantly higher than the sham operation group, the difference was statistically significant (immunohistochemical staining: F=105.893, 1 356.076, 434.026, 337.351; P<0.01; Western blot: F=92.906, 534.948, 327.600, 385.324; P<0.01). At different time points after modeling, the relative expression of TNF-α protein in the retina of the NAS group was significantly lower than that of the RIRI group (immunohistochemical staining: F=15.408, 570.482, 21.070, 13.767; P<0.05; Western blot: F=12.618, 115.735, 13.176, 111.108; P<0.05), but still higher than the sham operation group (immunohistochemical staining: F=40.709, 151.032, 156.321, 216.035; P<0.01; Western blot: F=33.943, 79.729, 74.057, 64.488; P<0.01), the difference was statistically significant; 12 h after modeling, Nrf2 in the retina of the NAS group (immunohistochemical staining: F=51.122, P<0.05; Western blot: F=33.972, P<0.05), HO-1 (immunohistochemical staining: F=30.750, P<0.05; Western blot: F=18.283, P<0.05) protein relative expression was significantly higher than that of RIRI group, and the differences were statistically significant. The results of linear regression analysis showed that the difference in the number of TNF-α + cells in the RIRI group and the NAS group was negatively correlated with the difference in the number of Nrf2 + and HO-1 + cells ( r 2=0.923, 0.936; P<0.01). Conclusions:NAS can inhibit the expression of TNF-α protein in the retina of RIRI rats and reduce RIRI. The mechanism may be related to the Nrf2/HO-1 pathway.

ABSTRACT

Objective:To evaluate clinical effect of tampon tamponade combined with wedge resection of the nail folds in the treatment of ingrown toenail-induced paronychia.Methods:A total of 96 patients with ingrown toenail-induced paronychia were collected from Department of Emergency Medicine, General Hospital of Ningxia Medical University between August 2017 and April 2019, and randomly and equally divided into 2 groups by using a random number table: control group treated surgically with the Winograd method, and treatment group treated with tampon tamponade combined with wedge resection of the nail folds. All the patients were followed up for 6 - 23 months after surgery.Results:Six months after operation, 47 (97.92%) and 41 (85.42%) cases were cured in the treatment group and control group respectively, and the cure rate significantly differed between the 2 groups ( χ2 = 4.909, P < 0.05) . The visual analogue scale scores for pain were significantly lower in the treatment group than in the control group on day 3 and 1 month after operation (both P < 0.05) . The postoperative recurrence rate and infection rate were 0 and 2.08% in the treatment group respectively, which were significantly lower than those in the control group (6.25%, 12.5%, respectively, both P < 0.05) . Conclusion:Tampon tamponade combined with wedge resection of the nail folds is effective for the treatment of ingrown toenail-induced paronychia with a simple operative procedure and a low postoperative recurrence rate, and is worthy of clinical promotion.

ABSTRACT

Objective:To explore the safety and efficacy of laparoscopic microwave ablation combined with partial nephrectomy in the treatment of cystic renal masses.Methods:The 19 patients with cystic renal masses undergoing laparoscopic microwave ablation combined with partial nephrectomy from November 2017 to December 2019 were retrospectively analyzed. There were 13 males and 6 females. The average age was 46.2 years. The mean body mass index was (25.8±3.1) kg/m 2. The masses located in the left kidney in 7 cases and the right kidney in 12 cases. The ECOG scores were 0. The mean maximum diameter of the tumors was (2.8±1.3) cm. Five cases were diagnosed with Bosniak Ⅲ and 14 cases with Bosniak Ⅳ. According to R. E.N.A.L. scoring, 11 cases were of low difficulty (4-6 points), 7 cases of medium difficulty (7-9 points) and 1 case of high difficulty (10-12 points). The cystic renal masses were ablated by laparoscopic microwave ablation, then followed by partial nephrectomy. Postoperative complications were observed and the prognosis was assessed by CT or MRI. Results:The mean duration of operation was (84.0±20.8) min. The median intraoperative blood loss was 20 (10-50) ml. The median duration of postoperative hospitalization was 3 (2-6) d, and no complications such as bleeding, infection, gross hematuria or urine leakage were observed. According to the malignant degree of cystic renal masses, the patients were divided into low-risk group and high-risk group. The patients with benign cystic kidney tumors or with low biological malignancy were considered as the low-risk group, while the patients with high malignant pathology were considered as the high-risk group. In the low-risk group, there were 4 patients, including 1 patient with papillary adenoma, 1 patient with renal angiomyolipoma, 1 patient with low-grade malignant potential multilocular cystic renal tumor, and 1 patient with renal chromophobe carcinoma (stage T 1a). In the high-risk group, there were 15 cases, including 14 cases of clear cell renal cell carcinoma (AJCC pathological stage: T 1a stage 11 cases, T 1b stage 3 cases; WHO/ISUP classification: 7 cases in grade 1, 6 cases in grade 2, and 1 case in grade 3); 1 case of Type 2 papillary renal cell carcinoma (stage T 1b, grade 2). The median follow-up was 20 months (12-37 months). Both groups survived, and no signs of tumor recurrence, implantation or metastasis were found in chest and abdomen imaging. Blood tests were performed regularly, and no significant abnormalities occurred. Conclusions:The safety and efficacy of laparoscopic microwave ablation combined with partial nephrectomy for the treatment of cystic renal masses is satisfactory, and postoperative pathology is clear, providing a potential option for cystic renal masses treatment.

ABSTRACT

Objective:To investigate the diagnostic performance of repeat biopsy 68Ga-PSMA PET/CT to distinguish between benign and malignant prostate disease. Methods:The clinical data and medical imaging of thirty-nine patients underwent repeat prostate biopsy were analyzed respectively in this study. The median age of patients was 65 years (range 46-81 years), the median PSA level was 11.0ng/ml (range 5.4-49.8 ng/ml), f/tPSA was 0.15(0.01-16.50)ng/ml, prostate volume was 43.80(7.79-108.63)ml, and PSA density was 0.24(0.09-2.31)ng/ml 2. All patients underwent pre-biopsy 68Ga-PSMA PET/CT and the standard transrectal ultrasound-guided systematic prostate biopsy. Based on the biopsy results, 68Ga-PSMA PET/CT images of all patients were visually and semi-quantitatively analyzed. By visual analysis, 68Ga-PSMA uptake in prostate was defined as focal, multimodal and inhomogeneous, and then the detection rate of prostate cancer in each subgroup was analyzed. The value of the ROC curve in the diagnosis of prostate cancer was analyzed based on the SUV max of prostate cancer(SUV max), tumor-to-normal-prostate background(SUV T/BGp)as semi-quantitative parameters of 68Ga-PSMA PET/CT. Results:Prostate cancer was detected in 18 patients (46.2%) and 12 patients (30.8%) had clinically significant disease. There were 11, 5 and 2 patients with prostate cancer respectively in men with a focal (12 patients), multifocal(7 patients) and inhomogeneous (20 patients) 68Ga-PSMA uptake. The ROC analysis revealed a SUV max 5.3 and SUV T/BGp1.8 as an optimal cut-off level to distinguish between non-prostate cancer and prostate cancer in 68Ga-PSMA PET/CT, the sensitivity and specificity were 100.0% and 85.7% for SUV max (AUC=0.979), 83.3% and 90.5% for SUV T/BGp (AUC=0.915). Conclusions:Pre-biopsy 68Ga-PSMA PET/CT could help to distinguish between benign and malignant prostate disease before repeat prostate biopsy and detect the foci of prostate cancer.

ABSTRACT

Objective:To investigate the predictive value of plasma high-sensitivity C-reactive protein/albumin ratio (HCRP/ALB) for the death in patients with acute coronary syndrome (ACS).Methods:The clinical data of patients with ACS [including unstable angina (UA), non-ST segment elevation myocardial infarction (NSTEMI), ST segment elevation myocardial infarction (STEMI)] admitted to Beijing Anzhen Hospital Affiliated to Capital Medical University from January 2018 to August 2020 were retrospectively analyzed. The plasma HCRP and ALB were recorded and the HCRP/ALB ratio was calculated. Patients were divided into death group and survival group according to the hospital outcome. The differences of baseline data and biochemical indexes between the two groups were compared. Receiver operating characteristic curve (ROC curve) was used to analyze the predictive value of each variable to death. Logistic regression was used to analyze the risk factors of death.Results:Among the 1 722 ACS patients, 74 died in hospital. Comparison of baseline data between death group and survival group showed that the other baseline data were statistically different except for the rate of hyperlipidemia. Among them, patients in death group had higher heart rate (HR), HCRP, B-type natriuretic peptide (BNP), HCRP/ALB [HR (bpm): 89±19 vs. 73±15, HCRP (mg/L): 23.24 (9.79, 33.69) vs. 3.57 (1.03, 14.26), BNP (ng/L): 424.0 (164.3, 1 596.1) vs. 79.0 (31.0, 211.4), HCRP/ALB: 0.700 (0.289, 1.017) vs. 0.089 (0.026, 0.368), all P < 0.01], while ALB was lower (g/L: 35.37±5.16 vs. 39.97±6.43, P < 0.01). ROC curve analysis showed that area under ROC curve and 95% confidence interval [AUC (95% CI)] of BNP, HCRP and HCRP/ALB for predicting death were 0.781 (0.717-0.845), 0.790 (0.724-0.856) and 0.803 (0.738-0.869), respectively. The Youden index of HCRP/ALB was 0.559, and the corresponding HCRP/ALB was 0.246. The patients were divided into low HCRP/ALB group (HCRP/ALB≤ 0.246, 1 163 cases) and high HCRP/ALB group (HCRP/ALB > 0.246, 559 cases). Except for gender, previous smoking, hypertension and diabetes rates, the other baseline data were statistically different between the two groups. Patients in the high HCRP/ALB group had a higher mortality (10.4% vs. 1.4%, P < 0.01), higher rates of implanted intra-aortic balloon pump (IABP, 12.7% vs. 2.7%, P < 0.01), higher BNP, HCRP, HCRP/ALB [BNP (ng/L): 253.0 (82.8, 749.0) vs. 60.0 (26.0, 145.2), HCRP (mg/L): 25.42±17.47 vs. 2.62±2.43, HCRP/ALB: 0.700±0.435 vs. 0.066±0.062, all P < 0.01], while lower ALB (g/L: 36.89±4.30 vs. 41.17±6.83, P < 0.01). Logistic regression analysis showed that higher HR [odds ratio ( OR) = 1.037, 95% CI was 1.020-1.055, P = 0.000] and higher HCRP/ALB ( OR = 3.835, 95% CI was 1.612-9.125, P = 0.002) were independent risk factors for the death in ACS patients, while higher ALB could reduce the mortality in ACS patients ( OR = 0.884, 95% CI was 0.818-0.957, P = 0.002). Conclusions:The higher the HCRP/ALB, the higher the risk of death in patients with ACS. When HCRP/ALB is greater than 0.246, the patient has a higher mortality. Therefore, HCRP/ALB in patients with ACS can be used as an effective predictor for death risk.

ABSTRACT

Protein kinase C(PKC) is a kind of kinase which is widely involved in cell proliferation and development. PKC(Wp-PKC) in Whitmania pigra body belongs to classic PKC. In order to investigate the effect of Wp-PKC on the development of Wh. pigra germ cells, 17β-estradiol(17β-E2)(100 ng·mL~(-1)) and methyltestosterone(MT)(150 μg·L~(-1)), 150 μg·L~(-1)(MT)+0.5 mg·L~(-1) PKC, 0.5 mg·L~(-1) PKC inhibitor were added to Wh. pigra culture water, and no addition group(control group) was added, and the effects on the development of Wh. pigra germ cells and the expression of Wp-PKC were observed. The results showed that: Wp-PKC in male gonads was always higher than that in female gonads; MT promoted the development of male gonads in Wh. pigra, while the expression of Wp-PKC was significantly higher than that in the control; 17β-E2 promoted the development of female gonads in Wh. pigra and Wp-PKC expression significantly lower than that of the control; while the development of the female and male gonads in the PKC inhibitor group was inhibited, the expression of Wp-PKC was significantly lower than that of the control. In summary, Wp-PKC may promote the development of Wh. pigra, especially the development of male gonads.

ABSTRACT

To systematically evaluate the clinical efficacy and safety of Danhong Injection combined with conventional therapy in improving diabetes mellitus complicated with coronary heart disease. Based on the online literature database(CNKI, Wanfang, VIP, PubMed, Web of Science, Cochran Library), the Chinese and English papers about the randomized controlled trial(RCT) of Danhong Injection in the treatment of diabetes mellitus complicated with coronary heart disease were searched comprehensively from the establishment of the databases to January 1, 2020. The papers were screened strictly according to the inclusion and exclusion criteria. Based on Jadad scale, the risk assessment of literature was carried out, and Meta-analysis was performed by STATA 12.0 software. Seventeen RCTs were included, involving 1 453 patients. The results of Meta-analysis showed that the combination of Danhong Injection and conventio-nal treatment could improve the clinical comprehensive effective rate(RR=1.47, 95%CI[1.38, 1.58], P<0.000 1), electrocardiogram(ECG) efficiency(RR=1.30, 95%CI[1.16, 1.46], P<0.000 1), efficiency of the angina pectoris(RR=1.41, 95%CI[1.25, 1.58], P<0.000 1), cholesterol level(SMD=-1.05, 95%CI[-1.95,-0.16], P=0.02), low-density lipoprotein(LDL) level(SMD=-0.50, 95%CI[-0.79,-0.21], P<0.000 1), coronary angina attack frequency(SMD=-3.71, 95%CI[-4.05,-3.36], P<0.000 1) and duration of angina pectoris(SMD=-2.96, 95%CI[-3.25,-2.66], P<0.000 1), with statistically significant differences. But the differences in fasting plasma glucose(FPG)(SMD=-0.19, 95%CI[-0.45, 0.08], P=0.16), plasma glucose of two hours after meal(2 hPG)(SMD=0.19, 95%CI[-0.11, 0.49], P=0.22), and high-density lipoprotein(HDL) level(SMD=0.10, 95%CI[-0.30, 0.49], P=0.62) after treatment were not statistically significant. Compared with the control group, there was no significant difference in adverse reactions(SMD=-2.96, 95%CI[-3.25,-2.66], P=0.75). The existing evidence shows that the combination of Western medicine and Danhong Injection can improve the clinical effect for diabetes mellitus complicated with coronary heart disease and has no obvious adverse reactions. However, due to the low level of overall literature evidence, high risk and some kind of publication bias, it still needs more high-quality randomized controlled trials and low-bias studies for further verification.

ABSTRACT

Protein kinase C(PKC) is a type of protein kinase widely involved in cell proliferation and development, but the developmental mechanism in the gonads of androgynous animals is still unclear. In order to explore the role of protein kinase C in the development of Whitmania pigra germ cells, the Wh. pigra PKC(Wp-PKC) gene was cloned, bioinformatics analysis was conducted, and fluorescent quantitative PCR was used to analyze the expression of female and male gonads. The results showed that:(1)The cloned Wp-PKC had a full length of 2 580 bp, a relative molecular weight of 76 555.19, and contains an open reading frame encoding 670 amino acids, Wp-PKC was closely related to Danio rerio PKC-α and rat PKC-γ. The similarity of amino acid sequence was 55% and 58%.(2)The protein encoded by Wp-PKC had no signal peptide and was a hydrophilic protein. The secondary structure is mainly composed of random coils, α-helices, extended chains, folds and folds, with the largest proportion of random coils and α-helices. Wp-PKC protein does not contain a transmembrane domain. Multiple sequence alignment and domain prediction analysis show that Wp-PKC contains 4 conserved domains of classical protein kinase C.(3)Fluorescence quantitative results showed that the expression of Wp-PKC in Wh. pigra gonads was positively correlated with the development of germ cells, and the expression in male gonads was significantly higher than that in female gonads. In summary, Wp-PKC is a classic PKC, and Wp-PKC may promote the development of Wh. pigra, especially the development of male gonads, and provide references for further research on the developmental mechanisms of Wh. pigra.

ABSTRACT

The research on the molecular mechanism of vascular injury has been a hot topic in recent years since the mechanism can be targeted for the treatment of vascular injury diseases. A large number of studies have found that vascular injury, repair and pathological remodeling are closely related to phenotype switching, abnormal proliferation and migration, and apoptosis of vascular smooth muscle cells (VSMCs). Smooth muscle 22α (SM22α) is a shape change and transformation sensitive F-actin-binding protein. SM22α decorates the contractile filament bundles within cultured VSMCs exhibiting differentiated phenotypes. In addition, SM22α is involved in regulation of cell signaling pathways related to vascular homeostasis and vascular remodeling. Here, we reviewed the recent research progress of SM22α in vascular homeostasis and remodeling.

ABSTRACT

OBJECTIVE@#To observe the effect of five-element acupuncture on the cognitive function repair of migraine patients with depression/anxiety disorder.@*METHODS@#The migraine patients with depression/anxiety disorder (19 cases, 5 cases dropped off) were taken as the observation group, and received five-element acupuncture twice a week for 8 weeks. Healthy subjects (19 cases) were selected by demographic data matching as the control group. The cognitive function was evaluated with the event related potential (ERP) technique, and the latency and amplitude of visual evoked potential P300 were adopted as the observation indexes. The headache days (every 4 weeks), headache intensity [visual analogue scale(VAS) score], and headache impact test-6 (HIT-6) score, Hamilton depression scale (HAMD) score and Hamilton anxiety scale (HAMA) score were used as the observation indexes for curative effect.@*RESULTS@#Before the treatment, latency of target stimulus at Fz [ (417.5±34.3) ms] in the observation group was extended compared with the healthy subjects of the control group [(388.6±42.1) ms, @*CONCLUSION@#There are some cognitive impairments in migraine patients with depression/anxiety disorder. Five-element acupuncture not only relieves headache, anxiety and depression effectively, but also improves the activation level of the frontal lobe. It significantly repairs the impaired cognitive function.

ABSTRACT

Purpose@#The aim of this study was to compare the efficacy of liver transplantation (LT) and liver resection (LR) for hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) and to investigate risk factors affecting prognosis. @*Materials and Methods@#A total of 94 HCC patients with PVTT type I (segmental PVTT) and PVTT type II (lobar PVTT) were involved and divided into LR (n=47) and LT groups (n=47). Recurrence-free survival (RFS) and overall survival (OS) were compared before and after inverse probability of treatment weighting (IPTW). Prognostic factors for RFS and OS were explored. @*Results@#Two treatment groups were well-balanced using IPTW. In the entire cohort, LT provided a better prognosis than LR. Among patients with PVTT type I, RFS was better with LT (p=0.039); OS was not different significantly between LT and LR (p=0.093). In subgroup analysis of PVTT type I patients with α-fetoprotein (AFP) levels >200 ng/mL, LT elicited significantly longer median RFS (18.0 months vs. 2.1 months, p=0.022) and relatively longer median OS time (23.6 months vs. 9.8 months, p=0.065). Among patients with PVTT type II, no significant differences in RFS and OS were found between LT and LR (p=0.115 and 0.335, respectively). Multivariate analyses showed treatment allocation (LR), tumor size (>5 cm), AFP and aspartate aminotransferase (AST) levels to be risk factors of RFS and treatment allocation (LR), AFP and AST as risk factors for OS. @*Conclusion@#LT appeared to afford a better prognosis for HCC with PVTT type I than LR, especially in patients with AFP levels >200 ng/mL.

ABSTRACT

Depression is one of the diseases with the highest disability rate in the world. A large number of studies have shown that the intake of unsaturated fatty acids can deal with depression while chronic overconsumption of saturated fatty acids is a risk factor for depression. It was suggested that the mechanism of saturated fatty acids inducing depression is related to the following four aspects: regulating the function which links to depression in whole brain and specific brain regions, including the hippocampus, the hypothalamic-pituitary-adrenal axis, the striatum, and the prefrontal cortex; stimulating the secretion of inflammatory factors; affecting the balance and function of metabolic regulatory hormones, including leptin, adiponectin, glucocorticoid, and insulin; inducing the disturbance of intestinal flora. This article reviews the relationship between dietary fatty acids and depression, and the possible mechanisms by which saturated fatty acids induce depression from the four aspects mentioned above.

ABSTRACT

Objective:To investigate the antiviral efficacy of direct-acting antiviral agents (DAAs) in the treatment of liver transplantation (LT) recipients with hepatitis C virus (HCV) infection.Methods:Twenty-two HCV-infected LT recipients treated with DAAs at Fifth Medical Center of Chinese PLA General Hospital from December 2014 to June 2018 were retrospectively analyzed, Twenty cases of HCV RNA gene type 1b were treated with sofosbuvir (400 mg/d) + ledipasvir (90 mg/d) or sofosbuvir (400 mg/d) + daclatasvir (60 mg/d) for 12 weeks or 24 weeks; 2 cases of gene type 2a were treated with sofosbuvir (400 mg/d) for 12 weeks. The effect of antiviral treatment, adverse reactions during treatment, and laboratory indicators such as HCVRNA quantification, blood routine, liver and kidney function during treatment and follow-up were studied.Results:The LT recipients of HCV infection included 16 males and 6 females, with a median age of 61.5 (36-71) years old, and the median time of antiviral treatment was 48 (2-117) months after transplantation. Among the 22 patients, 16 received a 12-week course of treatment. Except for 2 patients who did not get HCVRNA negative conversion at 4-week, all achieved a negative HCV RNA at 4-week and the end of the treatment. Six LT recipients received a 24-week course of treatment (gene type 1b), and HCVRNA was negative at 4-week and the end of treatment. All patients achieved end of treatment virological response and a sustained virological response (SVR) rate of 100% at 12 weeks and 24 weeks after the end of treatment. The serum levels of alanine aminotransferase (ALT) and creatinine were 71.5 (30, 110) U/L and (89.4±25.7) mmol/L before treatment, respectively. ALT decreased to 22 (17.8, 28.5) U/L after 4 weeks of treatment, and serum creatinine decreased to (77.4±11.5) mmol/L at 24 weeks after the end of treatment. The differences before and after treatment were statistically significant (all P<0.05). No serious adverse events occurred during the treatment. Conclusions:DAAs have a definite antiviral effect in the treatment of LT recipients with HCV infection, and long-term SVR can be obtained.

ABSTRACT

Objective:To study the clinical features of the "migration birds" population in Hainan Province in winter presenting with acute cholecystitis.Methods:Patients who were diagnosed to suffer from acute cholecystitis in the winter months from November to February of the following year of 2017, 2018 and 2019 and admitted in Hainan Hospital of Chinese PLA General Hospital were included in this study. The "migration birds" patients who arrived in Hainan Province in less than 30 days were defined as the short-term group ( n=49), 30-89 days as the mid-term group ( n=24), more than 90 days as the long-term group ( n=48). The general information, associated medical diseases, clinical presentations, interventional strategies and in-hospital outcomes were compared, and further analyze the clinical characteristics of patients with purulent cholecystitis and non-purulent cholecystitis in the short-term group. Results:Of 120 patients, there were 49 patients in the short-term group (29 males and 20 females with an average age of 65.18±15.02 years), 24 patients in the mid-term group (13 males and 11 females with an average age of 66.21±11.93 years), and 48 patients in the long-term group (30 males and 18 females with an average of 60.73±12.54 years). The general information, interventional strategies and in-hospital outcomes were similar among the three groups. When compared with patients in the long-term group, patients in the short-term group had higher incidences of hypertension [20.83% (10/48) vs 48.98% (24/49)] and diabetes [10.42% (5/48) vs 30.61% (15/49)]. The gallbladder wall in the short-term group was significantly thicker than that in the long-term group [0.60(0.40, 0.70) cm vs 0.50(0.30, 0.60) cm, P<0.017]. The proportion of purulent cholecystitis in the short-term group was significantly higher than that in the long-term group [48.15% (13/27) vs 17.24% (5/29) , P<0.017] . In the short-term group, the incidences of silt-like stones of purulent cholecystitis [38.46% (5/13) vs 14.29% (2/14)], gallbladder perforation [30.77% (4/13) vs 0], gallbladder gangrene [53.85% (7/13) vs 7.14% (1/14)], perigallbladder effusion [76.92% (10/13) vs 14.29% (2/14)], abdominal effusion [46.15% (6/13) vs 7.14% (1/14)] were significantly higher than that of patients with non-purulent cholecystitis, (all P<0.05). Conclusion:Patients presenting with acute cholecystitis after arrival in Hainan in the short term had more severe inflammation with complications of suppuration, perforation and gangrene. Patients with hypertension and diabetes were the high risk group of patients presenting with acute cholecystitis after short-term arrival in Hainan.
