ABSTRACT
Objective:To investigate characteristics of the 18F-flurodeoxyglucose ( 18F-FDG) uptake intensity and ranges in distinct hepatic alveolar echinococcosis lesions. Methods:The clinical data of 39 patients with position emission tomography during Jan 2017 to Dec 2019 in the First Affiliated Hospital of Xinjiang Medical University were enrolled. Among them, there were 17 males and 22 females, aging from 15 to 65 years (median 34 years). Lesions were classified into six groups based on heterogenic scales of calcification and liquefaction: A. non-calcified and non-liquefied ( n=7); B. obvious calcified and non-liquefied ( n=7); C. partial calcified and partial liquefied( n=10); D. obvious calcified and partial liquefied ( n=5); E. partial calcified and subtotal liquefied ( n=5); F. obvious calcified and subtotal liquefied ( n=5). Tumor to background ratio (TBR) and width (W) of lesion infiltrative boundary were measured and calculated. Statistical comparison using Mann-Whitney U test as well as correlation analysis was performed. Results:TBR values [ M( Q1, Q3)] for each group were 4.40(3.66, 7.03), 2.55(1.69, 3.60), 3.73(3.37, 5.21), 2.90(2.75, 3.60), 3.80(3.49, 6.36), 2.49(2.21, 3.97), among which A>B, A>D, A>F, C>B, E>B ( U=3.0, 4.0, 4.5, 11.0, 5.0, all P<0.05); From the perspective of the calcification in each group, it was found that the lighter the calcification was, the greater the TBR value was. W values [ M( Q1, Q3)] for each group were [12.5(10.0, 19.5), 11.2(10.5, 12.5), 12.2(10.9, 13.2), 7.8(7.3, 9.3), 10.0(7.3, 13.4), 7.3(6.8, 7.6)] mm, among which A>D, A>F, B>D, B>F, C>D, C>F (all U=0, all P<0.05); According to the degree of calcification and liquefaction of lesions in each group, the lighter the calcification was, the greater the W value was; The heavier the liquefaction was, the smaller the W value was. A mild strength linear correlation has been observed between the TBR value and W value ( r=0.4136, P<0.05). Conclusions:Less calcification and liquefaction implicated higher 18F-FDG uptake intensity and wider range. Radical resection margins and tissue sampling should be individualized based on different lesion features in surgical treatment.
ABSTRACT
Objective:To evaluate the safety and efficacy of endoscopic retrograde biliary drainage (ERBD) for acute obstructive suppurative cholangitis (AOSC) in the elderly.Methods:A retrospective analysis was performed on the clinical data of AOSC patients admitted to the First Affiliated Hospital of Xinjiang Medical University from January 2018 to January 2020. Patients aged 75 years and over ( n=49) were assigned to the elderly group and patients under 75 years old were assigned to the control group ( n=63). General data, American Society of Anesthesiologists (ASA) grading, procedure-related indicators, incidence of postoperative complications and mortality were compared. Results:There were significant differences in age (82.6±5.1 years VS 64.6±4.5 years, t=19.98, P<0.001), albumin levels (29.1±5.9 g/L VS 34.6±8.8 g/L, t=-3.94, P<0.001) and ASA grade ( χ2=8.37, P=0.015) in the elderly group and the control group . The elderly group were accompanied by more basic diseases, i.e. hypertension [57.14% (28/49) VS 34.9% (22/63), χ2=5.51, P=0.019], coronary heart disease [55.1% (27/49) VS 27.0% (17/63), χ2=9.14, P=0.003], chronic obstructive pulmonary diseases/asthma [24.5% (12/49) VS 6.3% (4/63), χ2=7.41, P=0.006]. There were no significant differences in the operation time (31.4±8.1 min VS 30.4±8.0 min, t=-0.61, P=0.543) or hospital stay (6.1±1.7 days VS 5.7±1.4 days, t=1.35, P=0.182). The incidences of postoperative complications were 14.3% (7/49) in the elderly group and 12.7% (8/63) in the control group, showing no significant difference ( χ2=0.06, P=0.807). No ERBD-related death was observed in either group during hospital stay. Conclusion:For elderly patients with AOSC over 75 years old, emergency ERBD, which can quickly relieve the disease, is safe and effective. Advanced age is not an absolute contraindication for emergency ERBD.
ABSTRACT
Objective:To investigate the feasibility, safety and efficacy of simultaneous combined surgery for hepatic and renal cystic echinococcosis (CE).Methods:Clinical data of consecutive 11 hepatic and renal CE patients undergoing surgical treatment at the First Affiliated Hospital of Xinjiang Medical University from Oct 2009 to Feb 2017 were analyzed retrospectively.Results:There were 8 males and 3 females, median age was 44 years (22-60 years). Main symptoms were abdominal and/or flank pain and fever; nine and 2 patients respectively had cysts in liver plus right kidney and left kidney; median volume of cyst load for each patient was 944.1 cm 3 (67.1-9 310.4 cm 3).

During the follow-up, cavernous transformation of the portal vein progressed in 3 patients, 2 of them esophageal varices rupture and bleeding.Conclusion:Radical hepatectomy and revascularization are the first choice for the treatment of hepatic alveolar echinococcosis complicated with secondary cavernous transformation of portal vein the result was fair.
ABSTRACT
Human alveolar echinococcosis is a chronic infectious disease caused by Echinococcus multilocularis infection. It predominantly injuries the liver and grows like the malignant tumor. The therapeutic options and prognosis depend on types of human alveolar echinococcosis, clinical stages, biological activity, vascular invasion, pathological characteristics, and patient's immune status. However, despite of multiple classification methods, there are still lacking of comprehensive typing schemes. which leads to inappropriate diagnosis and therapy. This research systematically reviewed the recent studies on human alveolar echinococcosis at home and abroad and analyzed the classifications based on ultrasound, computer tomography, magnetic resonance imaging, positron emission computed tomography, serology and pathology, and some novel technologies and summarized the individual advantage and disadvantage for each classification Relationships and their advantages plus disadvantages have been assessed comprehensively. Meanwhile, the possible reference factors or theoretical basis for optimized future classification are proposed, in order to establish a unified classification system to provide guidance for clinical diagnosis and treatment.
ABSTRACT
As two original plants of Tibetan herb Jieji, Gentiana waltonii Burk. and Gentiana lhassica Burk. belong to Section Cruciata of Gentiana, Gentianaceae. Here, we report on whole chloroplast genome sequences in the alpine species, respectively, and the features of plastomes were investigated. The plastome of G. waltonii is 148 705 bp long (148 652 bp in G. lhassica) and encodes 112 genes, including 78 protein-coding genes, 30 transfer RNA genes, and 4 ribosomal RNA genes. Two pseudogenes, namely ψrps16 and ψinfA, were found in plastomes. In addition, two novel loci were detected, and a species-specific polymerase chain reaction assay was developed for differentiating G. waltonii and G. lhassica from 10 alpine species in Section Cruciata. Gentiana. Our study provides basic data for identifying Tibetan herbs, alpine species conservation and molecular phylogenetic studies of Gentiana and Gentianaceae.
ABSTRACT
Objective:To explore the curative effect of laparoscopic surgery for hepatic cysticercosis.Methods:Search the literature from February 2010 to February 2020 on literature platforms such as Wanfang Data, VIP, CNKI, Pubmed, ScienceDirect, Web of Science, etc. the key words were "肝囊型包虫病" , "细粒棘球蚴" , "手术" , "开腹手术" , "腹腔镜" , "微创手术" , " echinococcosis " , " liver or hepatic " , " laparoscopic or minimal invasive " . Data on intraoperative indicators (e.g., operation time, bleeding volume), postoperative complications, hospital stay, recurrence rate, etc. in the literature included in the study were extracted and meta-analyzed.Results:A total of 9 articles were included, including 2 prospective studies and 7 retrospective case-control studies. A total of 1031 patients were enrolled, including 272 in the laparoscopic group and 759 in the laparotomy group. The results of the meta-analysis showed that the total postoperative complication rate in the laparoscopic group was lower than that in the laparotomy group ( OR=1.64, 95% CI: 1.10-2.45, P<0.05). Incision-related complications in the laparoscopy group and laparotomy group the difference was statistically significant ( OR=2.81, 95% CI: 1.03-7.70, P<0.05), and the hospital stay in the laparoscopic group was shorter ( SMD=1.21, 95% CI: 0.47-1.96, P<0.05). There was no significant difference between the two groups in operation time, postoperative bile leakage, residual cavity infection and effusion, and postoperative recurrence rate ( P>0.05). Conclusions:Under the premise of strictly grasping the indication of laparoscopic surgery, the incidence of complications after laparoscopic surgery is low, the hospitalization time is short.
ABSTRACT
OBJECTIVE@#To explore the relationship between effect of induction chemotherapy and prognosis in acute myeloid leukemia (AML) patients.@*METHODS@#The clinical data of 146 adult AML patients treated in Affiliated Hospital of Chifeng University from March 2015 to March 2018 were enrolled and retrospectively analyzed. Day 14 bone marrow biopsy (D14BM) cellularity and blast proportion, daily peripheral blood blast (PBB) clearance rate, time to PBB clearance and etc. were primarily observed after induction chemotherapy. All the patients were divided into Non-relapse survival group, Relapse survival group, Non-relapse death group and Relapse death group according to survival and recurrence situation during 2-year follow-up. The survival of the patients was analyzed by Kaplan-Meier. Univariate analysis of prognostic factors were performed by ordinal Logistic regression, and ROC curve was used to assess the prediction efficiency of those factors for the 2-year overall survival (OS) and relapse of the patients.@*RESULTS@#A total of 138 patients were included since 8 cases failed to be assessed clinically. Their 2-year OS rate was 65.94%. Age of the patients in Non-relapse survival group was lower than that in Relapse death group. The D14BM cellularities in Non-relapse survival group and Relapse survival group were lower than those in Relapse death group (P10%, while it was higher in patients with daily PBB clearance rate >20% than those with clearance rate≤20% (P0.05).@*CONCLUSION@#Bone marrow biopsy results and PBB clearance rate are related to prognosis in AML patients, which can offer certain predictive value in assessing 2-year OS of patients.

The family Gentianaceae are found mostly on the Qinghai-Tibet Plateau in China, which have important medicinal properties. Based on 27 published complete chloroplast genome sequences from Gentiana, Swertia, Halenia, Menyanthes, and Nymphoides of Gentianaceae, the chloroplast genome structure was analyzed. The cp genome sizes of 27 taxa range from 137 to 154 kb, and they contain 101-114 unique genes, including 67-80 protein-coding genes, 30 tRNA genes and four rRNA genes. Also, a Bayesian phylogenetic tree was constructed based on the 27 cp genome sequences with Pentalinon luteum (Apocynaceae) as the outgroup. The tree was topologically consistent with the treatments of traditional taxonomy, and the cp genome sequences have genus- or section-level resolution. In addition, we reviewed the significance of species identification within the family. These cp genome sequences could provide basic data for the endangered species conservation, the genetic analysis and pharmacognostic researches of herbs from Gentianaceae.
ABSTRACT
BACKGROUND@#Resting-state functional magnetic resonance imaging (rs-fMRI) is a promising method for the study of brain function. Typically, rs-fMRI is performed on anesthetized animals. Although different functional connectivity (FC) in various anesthetics on whole brain have been studied, few studies have focused on different FC in the aged brain. Here, we measured FC under three commonly used anesthesia methods and analyzed data to determine if the FC in whole brain analysis were similar among groups.@*METHODS@#Twenty-four male aged Wistar rats were randomly divided into three groups (n = 8 in each group). Anesthesia was performed under either isoflurane (ISO), combined ISO + dexmedetomidine (DEX) or α-chloralose (AC) according to the groups. Data of rs-fMRI was analyzed by FC in a voxel-wise way. Differences in the FC maps between the groups were analyzed by one-way analysis of variance and post hoc two-sample t tests.@*RESULTS@#Compared with ISO + DEX anesthesia, ISO anesthesia caused increased FC in posterior brain and decreased FC in the middle brain of the aged rat. AC anesthesia caused global suppression as no increase in FC was observed.@*CONCLUSION@#ISO could be used as a substitute for ISO + DEX in rat default mode network studies if the left temporal association cortex is not considered important.

ABSTRACT
OBJECTIVE: The aim of this study is to investigate labelings on dermatologic drugs for pregnant women and provide qualitative and quantitative pharmaceutical support for clinical use. METHODS: Labelings and formularies on pregnancy of topical drugs were analyzed and sorted according to classification on pregnancy use. Transdermal abilities of the drugs not forbidden nor avoided were evaluated through ACD/LAB 6.0 software and Potts-Guy formulation. Through TOXNET database and dose conversion equation, toxicities on animals were collected and human doses for pregnant women were calculated. RESULTS: In dermatologic drugs, there are 16 drugs forbidden, 8 not recommended/avoided/should not be used, 14 used with caution/weighed pros and cons, 7 used under instruction, 16 unclear or with no statement. In topical drugs not forbidden nor avoided, there are 9 drugs' logKp above-5, butenafine and sertaconazole with strongest transdermal abilities, 7 drugs' logKp influenced under pH5.5 or pH7.0, with a decline in logK'p compared with logKp, still 15 drugs not influenced by pH, 7 drugs' toxicities on animals unknown, 14 drugs' pregnancy human doses under 10 mgkg-1. CONCLUSION: Currently,only a few topical drugs' instructions on pregnancy are clear. With properties and animal experiments, better pharmaceutical support can be provided for clinical use on qualitative or quantitative reference.
ABSTRACT
OBJECTIVE: To analyze 13 judicial precedents involving off-label drug use and explore the legal interpretation on off-label drug use in China in order to provide experience for establishment of off-label drug use and clinical application. METHODS: Based on the law databases (China Judgements Online, Chinalawinfo, Jufaanli, Itslaw), 13 cases were searched and screened involving legal off-label drug use. The relationship was investigated and discussed between different results and characteristics of the 13 cases. RESULTS: In 13 cases, there are 2 cases probably reasonable for off-label use, 2 cases unreasonable but not correlated with patients′ outcomes, 9 unreasonable and with a causal relationship with patients′ outcomes. In the 9 unreasonable cases, there are 4 cases without sufficient evidence, 3 cases without informed consent, 1 case lack of monitoring after off-label use, 1 case with idiosyncratic reaction, and 1 case not consistent with the label of the drug used. CONCLUSION: Major deficiencies of off-label drug use in China are without sufficient evidence, lack of informed consent and with uncompleted system on off-label drug use. Establishing more completed and detailed system, investigating enough clinical evidence, better informed consent and monitoring after off-label use are important measurements to ensure safety on off-label drug use.
ABSTRACT
Objective To investigate the double T tube drainage method in the treatment of hepatic echinococcosis which ruptured into the common bile duct.Methods A retrospective study was conducted on 86 patients who were treated surgically for hepatic echinococcosis which had ruptured into the common bile duct at the First Affiliated Hospital of Xinjiang Medical University from June 2012 to December 2014.The average postoperative hospitalization,postoperative complications (residual cavity bile leakage and residual cavity effusion,residual cavity infection) and biliary complications of biliary tract infection were analyzed.Results Significant differences were found on the postoperative residual cavity complications in group A:(2,7.1％) when compared with Group B:(9,15.5 ％),and also on the postoperative hospitalization between the double T tube drainage group [group A:(7.1 ± 1.3) d] and the traditional T type tube decompression group [B group:(8.2 ± 1.5) d] (P ＜ 0.05).Conclusions The doubleT tube drainage in the treatment of hepatic echinococcosis which had ruptured into the common bile duct was simple,safe and effective.This treatment could completely cure residual cavity bile leakage,and it had the advantage of avoiding occurrence of common bile duct related complications caused by the traditional suture method for bile leakage.
