With the acceleration of the process of global integration, China’s international exchanges and cooperation with other countries have been further increased. The personnel exchange has led to the frequent occurrence of imported schistosomiasis from abroad, which seriously endangers people’s health. This paper reviews the prevalence and transmission risks of oversea imported schistosomiasis, providing the reference for the entry and exit health quarantine and prevention and control of schistosomiasis in China.

Objective To compare the approaches used for the assessment of disability adjust life years (DALYs) for advanced schistosomiasis japonica, so as to provide scientific evidence for accurate assessment of the burden of advanced schistosomiasis japonica. Methods The patients with advanced schistosomiasis japonica receiving treatment and assistance programs in Hunan Province in 2017 were enrolled, and the years lived with disability (YLD) for the patients with advanced schistosomiasis japonica was calculated using the common global burden of disease (GBD) estimation method, the modified GBD method with addition of common syndromes of advanced schistosomiasis japonica, and the quality of life assessment method. Results The YLDs of patients with advanced schistosomiasis japonica, the mean YLDs per capita, and the percentages of YLD were 673.94, 728.77 person-years and 1 761.99 person-years; 0.181, 0.196 person-years and 0.474 person-years; and 10.61, 11.48 person-years per 100 thousand persons and 27.75 person-years per 100 thousand persons with the common GBD method, modified GBD method and the quality of life method, respectively. The YLDs of the patients with advanced schistosomiasis japonica in Hunan Province estimated with the modified GBD method and the quality of life method were 8.14% and 2.61 times higher than that with the common GBD method. Of the major symptoms included in the calculation, the 5 symptoms with the greatest contribution to the burden of advanced schistosomiasis japonica included ascites, moderate anemia, severe anemia, diarrhea and hematochezia. Conclusion The quality of life method may more comprehensively assess the YLDs in patients with advanced schistosomiasis japonica than the common and modified GBD methods.

Parasitic diseases are common infectious diseases closely related to poverty,which are mainly endemic in the trop-ical and subtropical regions.Africa is the major epidemic area of parasitic diseases,and the global burden of malaria and schisto-somiasis is over 85% in Africa.This paper reviews the disease burden,regional distribution and control strategies of the main parasitic diseases in Africa,in order to promote the prevention and control of parasitic diseases in this area.

OBJECTIVETo evaluate the residual paralysis after a single intubating dose of rocuronium and its effect of residual paralysis after a single dose of rocuronium on the postoperative pulmonary function of patients undergoing laparoscopic gynecological surgeries.

METHODSSixty American Society of Anesthesiologists (ASA) I - II patients undergoing laparoscopic gynecological surgeries were randomly divided into rocuronium (R) group (n = 30) and rocuronium + neostigmine (R + N) group (n = 30).All patients received midazolam (0.02 mg/kg), fentanyl (1 microg/kg), propofol(1.5-2 mg/kg), and rocuronium (0.6 mg/kg) to facilitate tracheal intubation and no more relaxant thereafter. Anesthesia was maintained with isoflurane and nitrous oxide in oxygen (N(2)O:O(2) = 1:1). At the end of the procedure, neuromuscular blockade was not reversed in R group, while antagonism was accomplished with neostigmine (0.04 mg/kg) and atropine (0.02 mg/kg) in R + N group. Immediately after tracheal extubation and on arrival in the PACU, the train-of-four (TOF) ratio at the adductor pollicis of all patients were measured using acceleromyography. Forced vital capacity (FVC), forced expiratory volume in one second (FEV(1)), and peak expiratory flow rate (PEFR) of all patients were measured using spirometry before surgery, after administration of midazolam and fentanyl, immediately after tracheal extubation, on arrival in the PACU, and after the TOF ratio recovered to 1.0. The TOF ratio and pulmonary function between two groups were compared.

RESULTSImmediately after tracheal extubation and on arrival in the PACU, the mean TOF ratio in R group was significantly lower than that in R + N group (P < 0.05). The mean time to achieve TOF ratio of 0.9 and 1.0 in R group was significantly longer than in R + N group (P < 0.05). Immediately after tracheal extubation and on arrival in the PACU, FVC, FEV(1), and PEFR were significantly lower in R group than in R + N group (P < 0.05). FVC, FEV(1), and PEFR after administration of midazolam and fentanyl and after TOF ratio recovered to 1.0 were significantly lower than the baseline values in all patients (P < 0.01).

CONCLUSIONSAfter a single intubating dose of rocuronium, residual paralysis exists in the majority of patients undergoing laparoscopic gynecological surgeries. The pulmonary function is impaired after the surgery, even after recovery of TOF ratio to 1.0.

OBJECTIVETo investigate the changes of perioperative serum levels of interleukin-6 (IL-6), C-reactive protein (CRP), and cortisol, as well as gastric intramucosal pH (pHi) and plasma lactate, aiming to compare systemic changes and tissue perfusion during colorectal and orthopaedic surgical procedures.

METHODSTwenty patients were randomly assigned to two groups, 10 cases of operation on vertebral canal, 10 cases of colorectal radical operation. Venous blood was drawn at 1 day before operation, 2, 4, and 6 hours following skin incision, and 1 day after operation, in order to measure serum IL-6, CRP, and cortisol. pHi and plasma lactate were also measured at the same time points.

RESULTSSerum concentrations of IL-6 and cortisol increased gradually following operation, reaching the peak value at 6 hours from the beginning of operation. CRP was not detectable until the first day after operation. Peak concentration of IL-6 had positive relationship with CRP. These variables changed more significantly in colorectal group than that in orthopaedic group (P < 0.05). pHi decreased gradually, reaching the lowest level at 4 hours from the beginning of operation, and to more extent in colorectal group than that in orthopaedic group (P < 0.05).

CONCLUSIONIL-6 may reflect tissue damage more sensitively than CRP. Colorectal surgery might induce systemic disorder to more extent, in terms of immuno-endocrinal aspect as well as tissue perfusion, reflected with pHi.

OBJECTIVETo investigate the relationship between the circadian rhythm of perioperative cortisol secretion and neuropsychological states in patients undergoing coronary artery bypass grafting surgery.

METHODSForty male patients scheduled for elective coronary artery bypass grafting (CABG) under hypothermic cardio-pulmonary bypass (CPB) or off-pump were enrolled in this study. They were allocated into CPB group or off-pump group with 20 patients in each group. Blood samples were withdrawn during surgery at specific time-points and every 3 h for 24 h in the immediate postoperative period. Plasma cortisol was measured by radioimmunoassay. All subjects were investigated preoperatively as well as 7 to 10 d and 3 months postoperatively with a comprehensive neuropsychologic assessment, while depression and anxiety were assessed by Self-Rating Depression Scale and the State-Trait Anxiety Inventory respectively.

RESULTSDuring postoperative 24 h, three patients in the CPB group and 7 patients in the off-pump group were demonstrating a circadian secretion pattern, while they were disturbed in the remaining patients in both groups. Postoperative depression scores of patients in both groups were significantly higher than preoperative values. Postoperative anxiety scores of patients in the CPB group were significantly higher than those in the off-pump group. The CABG with CPB patients showed a significant deficit in the Digit Span subtest of the WAIS-R and the Stroop colour word interference test. The disturbed cortisol circadian secretion in the CPB group correlated with depression and the Stroop colour word interference test, whereas in the off-pump group it correlated with depression, Digit Span subtest (forward), symbol digit modalities test and the Stroop colour word interference test. Degree of depression correlated with some items of cognitive dysfunctions.

CONCLUSIONPerioperative secretion rhythm of cortisol in patients undergoing CABG surgery with CPB or off-pump was disturbed. The disordered cortisol may correlate directly or indirectly through mood with neuropsychological deficits.

BACKGROUNDAlthough the performance of target-controlled infusion (TCI) have been studied extensively, the accuracy and safety of a TCI system that targets the effect site remains to be demonstrated. This study was to investigate the relations of TCI of propofol to its concentrations in cerebral spinal fluid (CSF), the effect-site concentrations and bispectral index (BIS).

METHODSTwelve mongrel dogs were used for investigations. The target effect-site concentration was set at 3 microg/ml and the infusion was lasted for 15 minutes. CSF and blood samples were then collected and propofol concentrations were determined by using high performance liquid chromatography with fluorescence detection. BIS and hemodynamic data were monitored continuously.

RESULTSThe predicted plasma concentrations were generally overestimated. Median performance error (MDPE) and absolute median performance error (MDAPE) were -10.0% and 29.9% respectively. Propofol CSF concentrations were much lower than its effect-site concentrations. Changes in BIS were consistent with propofol concentrations in CSF, both of which changed direction at 5 minutes while the effect-site concentrations relatively lagged behind. Better correlation (r(2) = 0.9195) was found between BIS and CSF concentrations, when compared with that between BIS and effect-site concentrations (r(2) = 0.554).

CONCLUSIONWith 1% enflurane inhaled, the inconsistency of drug effect to the effect-site concentrations may result from inaccuracy of pharmacokinetic parameters. CSF may show effect-site concentrations more accurately than plasma when using target effect-site concentration infusion.

OBJECTIVETo observe the effectiveness of using cell saver (CS) during surgery on blood sparing and its impact on patient's hematology and coagulation function.

METHODSOne-hundred and thirty-eight patients undergoing elective surgery were recruited for intraoperative blood salvage using CS. Blood routine, blood chemistry and coagulation function were measured before surgery, after infusion of salvaged blood and postoperative day 1, respectively.

RESULTSIn total, 112,056 ml of packed red blood cells were collected, with a mean value of 812 ml per patient. The percentage of autologous blood transfusion volume to the total blood transfusion volume was from 48% to 89%. Allogenic blood transfusion rate was from 5% to 100%. Compared with the values before surgery, the hemoglobin concentration, platelet count, plasma total protein and fibrinogen concentration decreased significantly after the transfusion of salvaged blood and the first postoperative day (P < 0.05 or P < 0.01), while the prothrombin time was significantly prolonged (P < 0.05).

CONCLUSIONSThe use of CS during surgery can, to a certain extent, reduce the requirement of allogenic blood. However, reinfusion of large amount of salvaged blood may affect coagulation function.
