Objective:To investigate the changes of natural killer (NK) cells, natural killer T (NKT) cells and T lymphocytes in the peripheral blood after nanosecond pulse ablation of hepatic vesicular hydatid in rats with different energy levels.Methods:A total of 32 SD rats were randomly divided into hepatic vesicular hydatid model group, low voltage group (1 000 V), medium voltage group (1 500 V) and high voltage group (2 000 V). The hydatid model of rats was established by selective injection of 100 μl of echinococcosis head suspension with concentration of 500/100 μl into the left hepatic portal vein in all the 4 groups. After 3 months, nanosecond pulse therapy was applied to the left lobe vesicular hydatid lesions in the low voltage group, medium voltage group and high voltage group. On the third day after treatment, flow detector was used to calculate the ratio of CD 4+ T to CD 8+ T in peripheral blood of four groups by CD 3+ T, CD 4+ T, CD 8+ T, NK cells and NKT cells. Results:CD 3+ T was expressed in the high voltage group with (62.08±2.75)%, the medium voltage group with (63.84±7.73)%, the low voltage group with (55.19±8.55)% and the control group with (54.76±8.28)% ( P<0.05). CD 4+ T number was larger in high voltage group (43.7±6.51)% than medium voltage group (38.82±5.47)%, low voltage group (37.31±6.96)% and model group (38.12±3.04)% ( P<0.05). CD 8+ T ratio in the high voltage group was (20.03±2.40)%, the medium voltage group was (21.22±1.74)%, the low voltage group was (19.00±3.06)%, and the model group (20.56±3.98)%, with no statistically significant difference ( P>0.05). NK cells ratio in high voltage group was (6.49±1.60)%, medium voltage group was (3.02±0.32)%, low voltage group was (3.42±0.91)% and model group was (3.44±0.55)% ( P<0.05). NKT cells ratio in high voltage group was (1.53±0.16)%, medium voltage group was (0.82±0.09)%, in low voltage group was (0.70±0.17)% and model group (0.78±0.10)% ( P<0.05). CD 4+ T/CD 8+ T high voltage group was (2.26±0.65), medium voltage group was (1.90±0.40), low voltage group was (1.98±0.37) and model group was (2.06±0.35) ( P<0.05). Conclusion:High voltage (2 000 V) increased number of T, NK and NKT cells in peripheral blood compared with medium voltage (1 500 V) and low voltage (1 000 V), which may be the immune response of the body caused by nanosecond pulse ablation of hepatic vesicular hydatid in rats.

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.

Objective:To analyze the treatment and the impact of brain metastases on patients with hepatic alveolar hydatid disease.Methods:The data of 11 patients with hepatic alveolar hydatidosis with brain metastases treated at the First Affiliated Hospital of Xinjiang Medical University from January 2014 to December 2019 were retrospectively analyzed. There were 7 males and 4 females. The age range was 19~49 years, with an average of 34 years. Of 11 patients, 7 were treated with surgery combined with drugs and 4 with drugs only. Analyze the treatment and results of patients.Results:Of the 7 patients who were treated with surgery and drugs, 2 patients underwent hepatectomy. They were treated with regular postoperative oral medication and were well on follow-up. Three patients underwent only brain surgery. On follow-up from 1 to 3 years, one patient developed pneumonia with atelectasis, another patient developed ascites and jaundice with physical decline. The third patient was stable and had an independent life. Two patients underwent partial hepatectomy and hydatidectomy, with one patient requiring repeated hydatidectomies. On follow-up for one of these 2 patients for 5 years, the patient was home bound and could not take care of himself. The other patient was followed up for 3 years and was stable, alive and able of self-care. Four patients were treated with albendazole liposome, including one patient who developed ascites, a second one with weight loss, physical decline, limb edema and a third one with pleural effusion, pelvic effusion and pneumonia. These patients were still alive with improvement of symptoms on supportive treatment.Conclusion:The treatment of hepatic alveolar hydatidosis with brain metastases is still mainly surgery and anti-hydatid drugs. The prognosis of most patients was poor. The surgical principle is neurosurgery first, followed by surgery on liver, lung, spleen and other organs involved by hydatid disease.

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.
