Role of thymoquinone in treatment of pancreatic cancer / 临床肝胆病杂志

Pancreatic cancer is one of the cancers with the worst prognosis, and its high metastasis rate and resistance to chemotherapy drugs have always been the tough problems in the medical field. At present, the effect of thymoquinone on pancreatic cancer has attracted wide attention, and it can exert an antitumor effect in pancreatic cancer by inhibiting cancer cell proliferation, promoting cancer cell apoptosis, inhibiting invasion and metastasis, enhancing the sensitivity to chemotherapy drugs, and exerting an anti-inflammatory effect. This review briefly introduces the current research status of the association between thymoquinone and pancreatic cancer in China and globally, so as to provide a reference for subsequent research.

Effect of group mindfulness-based stress reduction therapy in managing comorbid depression in patients with stable chronic obstructive pulmonary disease / 四川精神卫生

BackgroundChronic obstructive pulmonary disease （COPD） is a common chronic respiratory disease， and patients with COPD often experience substantially emotional difficulties， such as anxiety and depression， all of which may cause serious detriment to the prognosis of patients. As a non-pharmacological intervention in clinical practice， group mindfulness-based stress reduction therapy （MBSR） is beginning to emerge， while has rarely been studied in COPD patients with concurrent emotional difficulties. ObjectiveTo evaluate the effects of group MBSR on depression， state of mindfulness and pulmonary function in stable COPD patients， so as to provide references for the application of group MBSR in patients with COPD. MethodsA total of 97 patients with stable COPD who were followed up in the Department of Respiratory and Critical Care Medicine of Mianyang Third People's Hospital from January to October 2019 were selected as the study objects， and they were assigned into study group （n=50） and control group （n=47） by random number table method. All individuals received routine medication therapy and an 8-week health education， based on this， participants in study group partook an 8-week intervention comprising group MBSR. At the baseline， 4 weeks and 8 weeks of intervention， participants were assessed with Self-rating Depression Scale （SDS）， Five Facet Mindfulness Questionnaire （FFMQ） and COPD Assessment Test （CAT）， as well as the pulmonary function testing. ResultsThere were 41 patients in study group and 42 cases in control group completed the study. The group * time interaction was interpreted as significant between two groups for SDS， FFMQ and CAT scores （F=54.858， 86.161， 69.862， P<0.01）. Baseline SDS， FFMQ and CAT scores of the two groups yielded no statistical difference between two groups （F=0.240， 0.052， 0.019， P>0.05）， while study group scored lower on SDS and CAT （F=12.900， 38.511， 7.797， 28.824， P<0.01） and higher on FFMQ （F=27.324， 82.412， P<0.01） than those of the control group after 4 and 8 weeks of intervention. With the prolongation of intervention time in study group， participants demonstrated an overall reduction in SDS and CAT scores （F=109.753， 124.144， P<0.01）， and an increase in FFMQ scores （F=228.194， P<0.01）. There were no between-group differences in forced expiratory volume in one second as percentage of predicted volume （FEV1%pred） after 4 and 8 weeks of intervention （F=0.104， P=0.748） ， and the within-group changes in FEV1%pred value over the intervention period in study group was not statistical （F=0.561， P=0.458）. ConclusionGroup MBSR may help relieve depressive symptoms， enhance mindfulness level， and alleviate clinical symptoms in stable COPD patients， but has no effect on pulmonary function. ［Funded by Mianyang Health and Health Commission Scientific Research Project （number， 201916）］

Effectiveness and safety of nanoknife ablation guided by real-time virtual sonography in treatment of locally advanced pancreatic cancer / 临床肝胆病杂志

ObjectiveTo investigate the effectiveness and safety of nanoknife ablation guided by real-time virtual sonography (RVS) in the treatment of locally advanced pancreatic cancer (LAPC). MethodsA retrospective analysis was performed for the clinical data of 27 patients with LAPC who attended The Fifth Affiliated Hospital of Zhengzhou University from April 2018 to October 2019, and according to the treatment method, the patients were divided into combination group (12 patients treated with IRE combined with chemotherapy) and control group (15 patients treated with chemotherapy alone). The chemotherapy regimen was gemcitabine combined with tegafur, gimeracil and oteracil potassium for both groups. Adverse reactions and complications were observed for the combination group during the perioperative period, and the two groups were compared in terms of the changes in myocardial enzymes, blood amylase, and carbohydrate antigen 19-9 (CA19-9) before treatment and at different time points after treatment, as well as remission rate (RR) and disease control rate (DCR) at 3 months after treatment and survival status during follow-up. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups, and the Wilcoxon test was used for comparison within each group; the Fisher’s exact test was used for comparison of categorical data between groups; the Kaplan-Meier method was used to analyze the survival status during follow-up. ResultsIn the combination group, there were 12 cases of adverse reactions and mild complications during the perioperative period, i.e., 9 Clavien-Dindo grade I cases and 3 grade II cases. All patients in the combination group experienced a transient increase in myocardial enzymes, which returned to normal within 7 days, and there were no significant changes in creatine kinase and lactate dehydrogenase on day 7 after treatment (P＞0.05); 9 patients had a significant increase in blood amylase on day 1 after surgery, which significantly decreased on day 7 after surgery and basically returned to normal on day 14 after surgery, and there was no significant change in blood amylase on days 7、14， and 1 month after surgery (P＞0.05). Before treatment, the level of CA19-9 was higher than the normal value in both groups, and the combination group had a significant reduction in CA19-9 at 1, 2, and 3 months after treatment (all P＜005); in the control group, the level of CA19-9 firstly decreased for a short time and then increased, while there was no significant change in CA19-9 at 1, 2, and 3 months after treatment (all P＞0.05). At 3 months after treatment, the combination group had significantly higher RR and DCR than the control group (RR: 75.0% vs 26.7%, P=0.021; DCR: 91.6% vs 53.3%, P=0043). During the median follow-up time of 13 months, compared with the control group, the combination group had significantly higher median progression-free survival time (10 months vs 5 months, P=0.014) and median overall survival time (18 months vs 10 months, P=0.034). ConclusionRVS-guided percutaneous nanoknife ablation has marked clinical effect and high safety in the treatment of LAPC and can be used as a new treatment option for patients who refuse or cannot tolerate laparotomy for ablation therapy.

Comparison of different methods of hepatic blood flow occlusion in hepatectomy for hepatic alveolar echinococcosis / 中华肝胆外科杂志

Objective:To compare the different methods of hepatic blood flow occlusion in hepatectomy for hepatic alveolar echinococcosis.Methods:A total of 49 patients with hepatic alveolar echinococcosis who underwent radical hepatectomy from January 2018 to January 2019 in Department of General Surgery, Qinghai Provincial People's Hospital were retrospectively studied. There were 22 males and 27 females, aged 10-62 years. The patients were divided into the Glisson group ( n=22) and the Pringle group ( n=27) according to the method used for hepatic blood flow occlusion during operation. For the Glisson group, intrahepatic blood flow was occluded at the Glisson pedicle. For the Pringle group, intrahepatic blood flow was occluded using the Pringle’s maneuvre. Intraoperative blood loss, operation time, postoperative liver function and postoperative complications were compared between the two groups. Results:There were no significant differences between the two groups in operation time, intraoperative blood loss and intraoperative blood transfusion (all P>0.05). The vascular occlusion time of blood flow in the Pringle group was 35 (30, 45) min, which was significantly longer than that of 20 (15, 26) min in the Glisson group ( P<0.05). The drainage tube in the Pringle group was removed after 8 (7, 12) d, which was significantly longer than that of 7 (6, 9) d in the Glisson group ( P<0.05). After operation, alanine aminotransferase, aspartate aminotransferase, total bilirubin and direct bilirubin in the Glisson group were significantly better than those in the Pringle group (all P<0.05). Postoperative complications occurred in 9 patients (40.9%, 9/22) in the Glisson group and 15 patients (55.6%, 15/27) in the Pringle group ( P>0.05). Conclusion:The liver function, and time of removal of abdominal drainage tube after Glisson pedicle hepatic blood flow occlusion in patients who underwent hepatectomy for hepatic alveolar echinococcosis were significantly better than the Pringle method.

Objective To determine the diagnosis value of urinary albumin(mAlb)/creatinine(Ucre) ratio in random urine from patients with early diabetic nephropathy.Methods From March 2015 to December 2016,98 case with simple diabetes and early diabetic nephropathy in Ankang Hospital of Traditional Chinese Medicine were selected,including 47 cases with simple diabetes and 51 cases with early diabetic nephropathy.And 60 healthy people were selected as control group.The mAlb and mAlb/Ucre ratios in morning urine,postprandial urine and random urine were detected for three times in three days,and the resluts were calculated and analyzed.Results In early diabetic nephropathy group,the mAlb concentration varied during different time periods,mAlb in morning urine [(60.5 ± 27.1)mg/L] and postprandial urine [(60.7 ± 26.7)mg/L] were significantly increased compared with that in random urine [(40.9 ± 25.1) mg/L] (F =9.551,P =0.000).The MAlb/Ucre ratios were stable in morning urine,postprandial urine and random urine of each period (P ＞ 0.05).The positive rate of mAlb/Ucre ratio was sharply higher than mAlb alone in random urine (90.2％ vs.62.7％).No statistically significant difference showed in positive rates of mAlb/Ucre ratio in subjects from different groups(the positive rate of morning urine specimen was 92.2％;postprandial urine 88.2％;random urine 90.2％,P ＞ 0.05).Conclusion Positive rate of mAlb/Ucre ratio changed slightly during different test periods,and is superior to mAlb alone in clinic application.Additionally,the positive rate of mAlb/Ucre ratio in random urine could serve as an indicator in early screening of early diabetic nephropathy.

A Case of Alveolar Echinococcosis Occurring in the Hilar Bile Duct

Echinococcosis is a disease caused by the Echinococcus species that parasitizes in humans. Alveolar echinococcosis (AE) which is caused by Echinococcus multilocularis is harmful to humans. AE mainly occurs in the liver and can be transferred to retroperitoneal lymph nodes, lung, brain, bone, spleen and other organs through lymphatic and blood vessels. Cholangiocarcinoma can occur in the intrahepatic and extrahepatic bile ducts and is more common in the hilar. We reported a case of hilar bile duct alveolar echinococcosis which was originally misdiagnosed an cholangiocarcinoma.
