RESUMEN
Hypertension and orthostatic hypotension (OH) often coexist in the range of cardiovascular autonomic dysfunction, especially in the elderly population, where antihypertensive therapy may be more likely to cause OH. The incidence rate of hypertension combined with OH is increasing year by year, which brings clinicians a clinical dilemma as to what measures to provide to hypertensive patients to prevent the occurrence of OH in the future. However, current clinical studies have shown that the management strategies based on pathophysiology are effective for most patients. This paper mainly elaborates on the complex relationship between OH and hypertension, and discusses the risk factors and prevention strategies of hypertension with OH, in order to provide theoretical support for the prevention of OH in patients with hypertension.

Objective:To explore if miR-133a is involved in the occurrence and development of hepatocellular carcinoma(HCC)via regulating G6PD.Methods:Bioinformatics analysis predicted the binding sites of miR-133a and G6PD;RT-PCR or western blot was used to assess the expres-sion of miR-133a and G6PD in HCC tissues and the adjacent normal tissues;CCK-8 and flow cy-tometry assays were performed to evaluate the effects of miR-133a/G6PD on cell proliferation,apop-tosis;Fluorescent reporter gene and western blot assays were used to assess the effect of miR-133a on G6PD expression.Results:miR-133a expression was decreased in HCC tissues while G6PD was increased(P0.01);Up-regulation of miR-133a significantly reduced G6PD expression(P<0.01);up-reg-ulation of miR-133a inhibited cell growth and promoted cell apoptosis(P<0.05),whereas these effects induced by miR-133a over-expression were all abolished when G6PD was up-regulated(P<0.01).Conclusion:miR-133a represses the occurrence and development of HCC via targeting G6PD.
RESUMEN
OBJECTIVE@#To investigate the efficacy and clinical results of total internal protection technique in anterior cruciate ligament reconstruction.@*METHODS@#A total of 56 patients undergoing anterior cruciate ligament reconstruction treated from January 2018 to December 2019 were selected. According to the different surgical methods, they were divided into total internal reconstruction group and standard bone tunnel group. There were 21 patients in the total internal reconstruction group, including 15 males and 6 females, aged from 20 to 48 with an average of (35.6±6.7) years old, and 35 patients in the standard tibial tunnel group, including 26 males and 9 females, aged 22 to 51 years old with an average of (33.7±9.6) years old. Preoperative examination of Lachman test was positive, magnetic resonance indicated anterior cruciate ligament rupture. There were no significant differences between the two groups in age, sex, body mass index, time from injury to ACL reconstruction, combined meniscus injury and operation method, operation time, ligament diameter, ligament length and other general information. Postoperative evaluation included operation duration, length and diameter of transplanted tendon after braid. International Knee Documentation Committee (IKDC) score, Lysholm score, Tegner score and perioperative complications 2 years after surgery.@*RESULTS@#Both groups were followed up, ranging from 24 to 30 months with an average of (26.9±3.4) months. Postoperative incision healing was good, and no failure or joint infection occurred at the last follow-up. There was no statistically significant difference between the two groups in IKDC score, Lysholm score and Tegner score before, 1 year and 2 years after surgery. However, IKDC score, Lysholm score and Tegner score at 1 year and 2 years after surgery.@*CONCLUSION@#The same postoperative function and stability of knee joint can be obtained by both the residual whole technique and the standardized reconstruction technique. In the residual whole group, only the semitendinosus muscle is taken, and the femoral thin muscle is retained, with greater tibial bone mass preserved, which is safe and effective in clinical practice.

Objective To investigate the preventive effect of schisandrin(SCH)on fetal neural tube defects(NTDs)of mice and its mechanism.Methods C57BL/6 mice were mated with female and male at a ratio of 2:1.Pregnant female mice with vaginal plug after mating were randomly divided into control group,model group,SCH group,and folic acid group,with 9 mice in each group.The NTDs fetal mice model was induced by intraperitoneal injection of all-trans retinoic acid(atRA)(7.5 mg/kg)on embryonic day 7.5(E 7.5 d).During E 0.5 d-E 11.5 d,pregnant rats in folic acid group were given folic acid[61.0 μg/(kg·d)]by gavage once a day,and pregnant rats in SCH group were given SCH[8.0 mg/(kg·d)]by gavage once a day.Fetal mice were removed by cesarean section on E 11.5 d.PC12 cells were divided into control group,model group and SCH group.PC12 cells were treated with atRA(20 μmol/L)for 12 hours to establish cell damage model in model group,and treated with SCH(2.5 μmol/L)for 24 hours in SCH group.Fetuses were identified NTDs by stereoscopic microscopy.HE staining was used to observe the closure of the neural tube.The expression levels of p-PI3K,Akt and p-Akt molecules in PI3K/Akt signaling pathway were detected by Western Blotting.Results Compared with control group,the incidence of NTDs was significantly increased in mice of model group(P<0.01);compared with model group,the incidence of NTDs was decreased in folic acid group and SCH group(P<0.01);compared with folic acid group,SCH group had a lower incidence of NTDs(P<0.01).Western Blotting results showed that compared with control group,the expression of p-PI3K and p-Akt protein in fetal tissues of model group was significantly decreased(P<0.01,P<0.05);compared with model group,there was no significant difference in expression of p-PI3K and p-Akt in fetal tissues of folic acid group(P>0.05),while the expression of p-PI3K and p-Akt protein in SCH group was significantly higher(P<0.05).Compared with control group,PC12 cells in model group showed lower expression levels of p-PI3K and p-Akt(P<0.05);compared with model group,PC12 cells in SCH group showed higher expression levels of p-PI3K and p-Akt(P<0.05).Conclusions SCH can reduce the incidence of atRA-induced NTDs in fetal mice,and its preventive effect is better than folic acid,which may be related to the activation of the PI3K/Akt signaling pathway.
RESUMEN
OBJECTIVE@#JieZe-1 (JZ-1), a Chinese herbal prescription, has an obvious effect on genital herpes, which is mainly caused by herpes simplex virus type 2 (HSV-2). Our study aimed to address whether HSV-2 induces pyroptosis of VK2/E6E7 cells and to investigate the anti-HSV-2 activity of JZ-1 and the effect of JZ-1 on caspase-1-dependent pyroptosis.@*METHODS@#HSV-2-infected VK2/E6E7 cells and culture supernate were harvested at different time points after the infection. Cells were co-treated with HSV-2 and penciclovir (0.078125 mg/mL) or caspase-1 inhibitor VX-765 (24 h pretreatment with 100 μmol/L) or JZ-1 (0.078125-50 mg/mL). Cell counting kit-8 assay and viral load analysis were used to evaluate the antiviral activity of JZ-1. Inflammasome activation and pyroptosis of VK2/E6E7 cells were analyzed using microscopy, Hoechst 33342/propidium iodide staining, lactate dehydrogenase release assay, gene and protein expression, co-immunoprecipitation, immunofluorescence, and enzyme-linked immunosorbent assay.@*RESULTS@#HSV-2 induced pyroptosis of VK2/E6E7 cells, with the most significant increase observed 24 h after the infection. JZ-1 effectively inhibited HSV-2 (the 50% inhibitory concentration = 1.709 mg/mL), with the 6.25 mg/mL dose showing the highest efficacy (95.76%). JZ-1 (6.25 mg/mL) suppressed pyroptosis of VK2/E6E7 cells. It downregulated the inflammasome activation and pyroptosis via inhibiting the expression of nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing protein 3 (P < 0.001) and interferon-γ-inducible protein 16 (P < 0.001), and their interactions with apoptosis-associated speck-like protein containing a caspase recruitment domain, and reducing cleaved caspase-1 p20 (P < 0.01), gasdermin D-N (P < 0.01), interleukin (IL)-1β (P < 0.001), and IL-18 levels (P < 0.001).@*CONCLUSION@#JZ-1 exerts an excellent anti-HSV-2 effect in VK2/E6E7 cells, and it inhibits caspase-1-dependent pyroptosis induced by HSV-2 infection. These data enrich our understanding of the pathologic basis of HSV-2 infection and provide experimental evidence for the anti-HSV-2 activity of JZ-1.

Osteoclast (OC) is multinucleated, bone-resorbing cells originated from monocyte/macrophage lineage of cells, excessive production and abnormal activation of which could lead to many bone metabolic diseases, such as osteoporosis, osteoarthritis, etc. Autophagy, as a highly conserved catabolic process in eukaryotic cells, which plays an important role in maintaining cell homeostasis, stress damage repair, proliferation and differentiation. Recent studies have found that autophagy was also involved in the regulation of osteoclast generation and bone resorption. On the one hand, autophagy could be induced and activated by various factors in osteocalsts, such as nutrient deficiency, hypoxia, receptor activator of nuclear factor(NF)-κB ligand(RANKL), inflammatory factors, wear particles, microgravity environment, etc, different inducible factors, such as RANKL, inflammatory factors, wear particles, could interact with each other and work together. On the other hand, activated autophagy is involved in regulating various stages of osteoclast differentiation and maturation, autophagy could promote proliferation of osteoclasts, inhibiting apoptosis, and promoting differentiation, migration and bone resorption of osteoclast. The classical autophagy signaling pathway mediated by mammalian target of rapamycin complex 1(mTORC1) is currently a focus of research, and it could be regulated by upstream signalings such as phosphatidylinositol 3 kinase(PI-3K)/protein kinase B (PKB), AMP-activated protein kinase(AMPK). However, the paper found that mTORC1-mediated autophagy may play a bidirectional role in regulating differentiation and function of osteoclasts, and its underlying mechanism needs to be further ciarified. Integrin αvβ3 and Rab protein families are important targets for autophagy to play a role in osteoclast migration and bone resorption, respectively. In view of important role of osteoclast in the occurrence of various bone diseases, it is of great significance to elucidate the role of autophagy on osteoclast and its mechanism for the treatment of various bone diseases. The autophagy pathway could be used as a new therapeutic target for the treatment of clinical bone diseases such as osteoporosis.

Objective:To investigate the prevalence of hyperuricemia (HUA), patients′ awareness of HUA, and related factors among elderly in community.Methods:The health check-up data of 6 897 residents aged over 65 years in Gumei Community of Shanghai were collected from January 2019 to January 2020. There were 1 156 subject with increased serum uric acid levels (HUA group) and 5 741 with normal uric acid levels (non-HUA group). The differences of clinical indicators between HUA group and non-HUA group were analyzed and the risk factors of HUA was determined by multivariate logistic stepwise regression. A questionnaire survey on the knowledge of HUA and the adoption of relevant health behaviors was conducted among HUA patients.Results:The overall prevalence was 16.8% (1 156/6 897) in this population. The prevalence in males was significantly higher than that in females[26.4%(842/3 195) vs. 8.5%(314/3 702), P<0.001); and the prevalence in females increased with age (χ 2=7.56, P=0.023). Body mass index(BMI), waist circumference(WC), total cholesterol(TC), triglyceride(TG), serum creatinine, alanine aminotransferase(ALT) and albumin/urine creatinine ratio(UACR) in the HUA group were significantly higher than those in the non-HUA group, while estimated glomerular filtration rate(eGFR) and high-density lipoprotein(HDL) were lower than those in the non-HUA group (all P<0.01). The prevalence of hypertension, decreased renal function, overweight or obesity, abdominal obesity, fatty liver and renal cyst in HUA group was significantly higher than that in non-HUA group (all P<0.01). High values of TG, low-density lipoprotein(LDL), WC, hypertension and fatty liver were risk factors for HUA( OR=1.14, 1.20, 1.03, 1.43, 2.19; P<0.01); while female gender, eGFR, HDL and glycosylated hemoglobin A1c(HbA1c) were protective factors for HUA( OR=0.32, 0.94, 0.65, 0.78; P<0.01). The questionnaire survey was conducted among 1 090 HUA patients, and the results showed that 73.2% (798 cases) were aware of the disease after the health check-up results released; only 30.9% (337 cases) knew the diagnostic criteria of HUA, 21.1% (230 cases) knew that HUA needed life-long follow-up care, 56.3% (614 cases), 49.2% (536 cases) and 47.9% (522 cases) thought that HUA should eat less seafood, broth and soya bean products, 17.0%(185 cases) were atcohol drinker and the awareness rates of above questions in patients with gout were higher than those in patients without gout ( P<0.05). Conclusion:The study shows that the prevalence of HUA among the elderly in Gumei community of Shanghai is high, and the HUA related knowledge levels and health behavior performance are not ideal, especially for HUA patients without gout, therefore health education should be strengthened for elderly residents in the community.
RESUMEN
Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disease characterized by neuro-ophthalmic intercross and humoral immunity.Neuromyelitis optica related optic neuritis (NMO-ON) is often the initial symptom of NMOSD patients, with a high blinding rate, which brought a heavy blow to the quality of life, study, work and other aspects of patients.The discovery of aquaporin-4 immunoglobulin G (AQP4-IgG) has brought significant progress in the pathogenesis, diagnosis and treatment of NMOSD.However, AQP4-IgG is not a universal biomarker of NMOSD.The role of CD4 + T helper (Th) cell related cytokines in the pathogenesis of NMOSD has been increasingly emphasized.This paper reviewed the research results of CD4 + Th cell-related cytokines closely related to the occurrence of NMOSD in recent years, including Th17 cell-related cytokines such as interleukin-6 (IL-6), IL-17, IL-21, Th2 cell-related cytokines such as IL-4, IL-5, IL-13, IL-31, IL-33, and regulatory T cell-related cytokines, etc.to provide new insights for the pathogenesis, diagnosis and treatment strategies of NMOSD or NMO-ON.

OBJECTIVE@#To observe the effect of electroacupuncture (EA) on postoperative ileus after laparotomy for gastrointestinal cancer.@*METHODS@#A total of 90 patients with postoperative ileus after laparotomy for gastrointestinal cancer were randomized into an EA group and a conventional treatment group, 45 cases in each one. In the conventional treatment group, the postoperative fast track surgical regimen was accepted. In the EA group, on the base of the treatment as the conventional treatment group, acupuncture was applied to Zusanli (ST 36), Shangjuxu (ST 37), Yinlingquan (SP 9) and Taichong (LR 3) and electric stimulation was attached on Zusanli (ST 36) and Yinlingquan (SP 9), with continuous wave, 2 Hz in frequency and 3-5 mA in intensity. Acupuncture was provided once daily till the onset of postoperative exhaust and defecation. The first postoperative exhaust time, the first postoperative defecation time, the postoperative hospital stay and the wound pain under standing on the next morning after entering group were compared in the patients between the two groups. The impact of the EA expectation was analyzed on the first postoperative exhaust time, the first postoperative defecation time and the postoperative hospital stay separately.@*RESULTS@#The first postoperative exhaust time and the first postoperative defecation time in the EA group were earlier than the conventional treatment group (P<0.05), the postoperative hospital stay was shorter than the conventional treatment group (P<0.05), and the rate of wound pain in the postoperative standing was lower than the conventional treatment group (P<0.05). EA expectation had no obvious correlation with the clinical therapeutic effect (P>0.05).@*CONCLUSION@#EA can relieve postoperative ileus symptoms, alleviate pain and shorten hospital stay in the patients after laparotomy for gastrointestinal cancer.

CCK-8 kit was used to measure the level of cell proliferation, Transwell method was used to measure the abilities of cell invasion and migration, flow cytometry was used to measure the level of apoptosis, and qRT-PCR and Western blotting were used to measure hepatocyte growth factor (HGF) and c-Met mRNA and protein levels.Results:The survival rates of the control group, 5-fluorouracil group, low-dose propofol group and high-dose propofol group were (83.32±3.02) %, (36.29±3.54) %, (62.01±4.69) % and (40.20±5.48) % ( F=8.65, P=0.006) ; the apoptosis rates were (2.36±0.41) %, (12.47±0.40) %, (6.28±0.39) % and (10.24±0.37) % ( F=26.73, P=0.001) . Further pairwise comparison showed that there were statistically significant differences (all P<0.05) . The numbers of penetrating membranes of the four groups were 617.45±29.86, 125.27±24.38, 407.02±32.27 and 230.74±31.59 ( F=18.33, P=0.002) ; the migration distances were (603.85±27.74) μm, (121.69±25.85) μm, (395.59±28.37) μm and (233.52±30.42) μm ( F=27.02, P=0.001) . Further pairwise comparison showed that there were statistically significant differences (all P<0.05) . HGF mRNA expression levels of the four groups were 6.26±0.39, 1.94±0.35, 4.15±0.37 and 2.90±0.33 ( F=25.31, P=0.001) ; c-Met mRNA expression levels were 5.85±0.30, 2.04±0.32, 3.89±0.31 and 2.94±0.32 ( F=12.12, P=0.003) ; HGF protein expression levels were 1.43±0.04, 0.34±0.08, 0.86±0.06 and 0.63±0.09 ( F=17.02, P=0.001) ; c-Met protein expression levels were 1.63±0.14, 0.39±0.15, 0.93±0.11 and 0.64±0.17 ( F=19.89, P=0.001) . Further pairwise comparison showed that there were statistically significant differences (all P<0.05) . Conclusion:Propofol has obvious inhibitory effects on the malignant biological behaviors of prostate cancer DU145 cells, and the inhibitory effect of high-dose propofol is more obvious. The mechanism may be related to the inhibition of HGF and c-Met mRNA and protein expressions of DU145 cells by propofol, which inhibits the activation of HGF/c-Met pathway.
RESUMEN
Objective: To compare the short-term efficacy and long-term prognosis of laparoscopic and laparotomy radical resection for gallbladder cancer(GBC). Methods: From January 2010 to December 2020,the clinical data and survival information for 133 patients who underwent radical resection of GBC at the Department of Hepatopancreatobiliary Surgery,Zhejiang Provincial People's Hospital,were retrospectively collected. Eighty patients(23 males and 57 females) underwent laparoscopic radical resection and had a median age(M(IQR)) of 66.0(12.8)years(range:28.0 to 82.0 years). Fifty-three patients(45 males and 8 females) who received laparotomy were 63.0(6.0)years old(range:45.0 to 80.0 years old). There were no significant differences in age,gender,body mass index,preoperative albumin,preoperative total bilirubin,N stages,vascular invasion,peri-neural invasion or tumor differentiation between the laparoscopic and laparotomy group(all P>0.05). But there were significant differences in preoperative CA19-9(Z=-2.955, P=0.003), preoperative ALT level(Z=-2.801,P=0.031) and T stage (χ2=19.110,P=0.007) between the two groups. A non-parametric test was used for quantitative data. χ2 test or Fisher exact probability method was used for count data. Results: Patients in the laparoscopic group did not differ from those in the laparotomy group in terms of length of operation,number of lymph node yield,number of positive lymph nodes,the incidence of intraoperative gallbladder rupture,incidence of postoperative bile leakage,abdominal bleeding or abdominal infection,30-day mortality,90-day mortality, the incidence of incision implantation or peritoneal cavity metastasis(all P>0.05). Patients in the laparoscopic group showed less intraoperative bleeding(100.0(200.0)ml vs. 400.0(250.0)ml)(Z=-5.260,P<0.01),fewer days with drainage tube indwelling(6.0(3.8)days vs. 7.0(4.0)days)(Z=-3.351, P=0.001), and fewer postoperative days in hospital(8.0(5.0)days vs. 14.0(7.5)days)(Z=-6.079,P<0.01) than those in the laparotomy group. Patients in the laparoscopic group displayed better overall survival (P<0.01) and progression-free survival (P<0.01). Subgroup analysis for GBC of T1b-T2 and T3 stages revealed comparable overall survival and progression-free survival between the laparoscopic and laparotomy groups (P>0.05). Conclusions: Laparoscopic radical resection can achieve long-term survival for GBC comparable to that with open surgery. Laparoscopic radical resection has advantages over open surgery regarding surgical trauma and postoperative recovery.

Objective:To investigate the changes of serum catecholamines (CST) and oxidative stress index in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) with hypertension and the correlation with blood pressure.Methods:Total of 100 OSAHS patients admitted to Jingmen No.1 People′s Hospital from February 2018 to August 2020 were selected. According to whether patients combined with hypertension, they were divided into OSAHS group (54 cases) and OSAHS combined with hypertension group (46 cases). The changes of serum CST and oxidative stress index in the two groups were compared and analyzed the correlation of blood pressure and CST and oxidative stress index.Results:The level of myeloperoxidase(MPO) in the OSAHS combined with hypertension group was higher than that in the OSAHS group: (41.67 ± 3.02) U/L vs. (39.11 ± 2.65) U/L; the levels of catalase (CAT) and CST in the OSAHS combined with hypertension group were higher than those in the OSAHS group: (11.47 ± 2.54) kU/L vs. (15.88 ± 2.31) kU/L, (23.63 ± 4.38) ng/L vs. (28.61 ± 5.42) ng/L, there were statistically differences ( P<0.05). The levels of respiratory disturbance index, lowest oxygen saturation, triacylglycerol, total cholesterol, low density lipoprotein cholesterin, high density lipoproteincholesterol, epinephrine, noradrenaline in the two groups had no significant differences ( P>0.05). Spearman correlation analysis showed that the systolic pressure and diastolic pressure had positive correlation with MPO ( P<0.05), and had negative correlation with CAT and CST ( P<0.05). Conclusions:The serum CST and CAT are down-regulated in patients with OSAHS with hypertension, and serum MPO is up-regulated. Oxidative stress may be related to OSAHS with hypertension.

According to the different operative methods, the patients were divided into two groups. Inside-out group, from central compartment to peripheral compartment;Outside-in group, from peripheral compartment to central compartment. There were 14 males and 10 females in Inside-out group with an averageage of (39.8±7.6)years old, 13 males and 11 females in Inside-out group with an average age of (39.5±9.1)years old in Outside-in group. There was no significant difference in age, gender, body mass index, side, impingement type, medical history and follow-up time between the two groups. The complication occurrence rate, modified Harris hip score (mHHS)and nonarthritic hip score (NAHS) were compared between these two groups.@*RESULTS@#The mHHs and NAHS scores of the two groups were significantly higher than those before operation, but there was no significant difference between the two groups (@*CONCLUSION@#Both hip arthroscopic surgery methods can obtain satisfactory clinical efficacy in the treatment of FAI, but the incidence of postoperative complications of Outside-in surgical method is lower. The out-side in method can be preferentially selected for the patients with the indications of operation.

Cancer-related fatigue (CRF) is a common symptom which associated with cancer itself or cancer treatments. CRF will not only interrupt the patient's treatment, but also affect the patient's quality of life seriously. To date, the pathogenesis of CRF is still unclear, and recognized effective treatment is lacking. It is the precondition of establishing standardized animal models for CRF to find effective treatments. This paper summarizes the animal model of CRF in order to find suitable methods, and distinguish the effects of different interventions.
RESUMEN
Objective To evaluate the effects of DNA examination of trace bloodstain samples from the scene collected with Trace Biological Evidence Collection kit. Methods Venous blood was made into bloodstains on the ground. The trace bloodstain samples were collected with Trace Biological Evidence Collection kit and common methods, respectively. DNA examination of trace bloodstain samples (50 from each group) was conducted on the constant temperature shaker for 2, 24, 48, 72, and 96 h, respectively, and the examination results of every group were compared. Results When the trace bloodstain samples were placed on the constant temperature shaker for 24, 48, 72, and 96 h, the DNA detection rates in the group which used Trace Biological Evidence Collection kit (100.00%, 100.00%, 100.00%, 96.00%) were significantly higher than those in the group using common methods (62.00%, 26.00%, 10.00%, 0), the differences had statistical significance (P<0.05). When the trace bloodstain samples were placed on the constant temperature shaker for 2 h, the differences of DNA detection rates between the two groups had no statistical significance ( P>0.05). Conclusion The Trace Biological Evidence Collection kit can effectively improve DNA detection rate and extend detection time limit for trace bloodstain samples from the scene that have been stored for a relatively long time.

Objective To analyze the endemic situation of schistosomiasis in national surveillance sites of Zhejiang Province, so as to provide the scientific evidence for formulating the new schistosomiasis surveillance program and consolidating schistosomiasis elimination achievements. Methods A total of 54 to 55 national surveillance sites and 6 risk monitoring sites were assigned in historical endemic regions of Zhejiang Province from 2015 to 2019, where the Schistosoma japonicum infections in humans, livestock, snails and wild feces were monitored. All data pertaining to the surveillance results were descriptively analyzed. Results There were 34 530 person-time local residents receiving serological screening for S. japonicum infections in national surveillance sites of Zhejiang Province from 2015 to 2019, and the seroprevalance of S. japonicum infections were 0.29% to 0.68%; however, no egg-positives were detected. During the period from 2015 to 2019, there were 62 086 person-time mobile populations receiving serological screening for S. japonicum infections in national surveillance sites of Zhejiang Province, and the seroprevalance of S. japonicum infections were 0.32% to 0.56%; additionally, there were 27 egg-positives identified, including 3 imported cases with schistosomiasis haematobia and one case with acute schistosomiasis japonica, indicating that the adjusted prevalence of Schistosoma infections were 0.01% to 0.07% among mobile populations. A total of 829 livestock were examined for S. japonicum infections, with no positives detected. There were 10.55 hm2 and 2.89 hm2 snail habitats found in national surveillance sites and risk monitoring sites of Zhejiang Province during the 5-year period, respectively; however, no S. japonicum infections were identified in snails. Moreover, a total of 305 wild feces were tested for S. japonicum infections, and no egg-positives were identified. Conclusions The schistosomiasis elimination achievement have been consolidated in Zhejiang Province; however, the risk factors of re-emerging schistosomiasis have not been completely eliminated, such as residual snails and imported schistosomiasis cases. Further surveillance and control activities of snails and the source of S. japonicum infections should be reinforced.
RESUMEN
The present study is to investigate the absorption characteristics of the main components in Polygonum orientale extract in normal and isoproterenol-induced myocardial ischemia model rats with everted intestinal sac models. Intestinal sac fluid samples were collected in different part of intestine(duodenum, jejunum, ileum, colon) at different time after administration of different concentration of P. orientale extract(5.0,10.0, 20.0 mg·mL~(-1)). An UPLC-TQD method was employed for the determination of six components including orientin, isoorientin, vitexin, protocatechuic acid, kaempferol-3-O-β-D-glucoside and quercitrin in the intestinal sac samples. The absorption rate and cumulative absorption were calculated to analyze the intestinal absorption characteristics of six components in normal and myocardial ischemia model rats. The P-glycoprotein(P-gp) inhibitor was applied to investigate influence of intestinal absorption of six components in P. orientale extract. The results showed that the main absorption sites were concentrated on the duodenum at low concentration, while they were the colon at the medium concentration and the ileum at high concentration in control groups. In the condition of myocardial ischemia model, the main absorption sites focus on the ileum and jejunum at low concentration; the main absorption sites were in the ileum at the medium concentration and main absorption sites were the duodenum and ileum at high concentration. Compared with the normal group, the absorption rate and cumulative absorption of the six components significantly decreased in the model group. P-gp inhibitor markedly increased the absorption rate and cumulative absorption of six components in the model group, inferring that the 6 components may be the substrates of P-gp, and the mechanism needs further study. In this study, it is revealed that the six components of P. orientale extract can be absorbed into the intestinal sac, and it is an effective method to assess the intestinal absorption characteristics of P. orientale extract through everted intestinal sac model, providing data support for the clinical application and further development of P. orientale.
