ABSTRACT
The hepatic echinococcosis is an anthropozoonosis and caused by the larva of Echinococcus. The main pathogenic type of Echinococcus in China is E. granulosus and E. multilocularis, which cause cystic echinococcosis and alveolar echinococcosis respectively. At present, the treatment of hepatic echinococcosis has made great progress, but there are still some difficulties in the treatment of complex echinococcosis, especially of the cases existing one or more complications, and the focus of infection encroaching the hepatic portal, important vessels and bile vessel. This paper based on the literature reports and clinical experiences in recent years, puts forward the surgical treatment strategy for complex hepatic echinococcosis.
ABSTRACT
Objective To investigate the distribution characteristics of gallbladder diseases in children with hepatic alveolar echinococcosis, and to analyze the related factors for hepatic alveolar echinococcosis and gallbladder diseases. Methods The clinical data of hepatic alveolar echinococcosis patients under 18 years were collected in Qinghai Provincial People’s Hospital-from January 2012 to December 2017, and the gallbladder-related complications in the surgically treated patients with hepatic al-veolar echinococcosis were analyzed. Results The clinical data of 51 child patients with hepatic alveolar echinococcosis were collected and analyzed. According to the PNM classification criteria of WHO, P1, P2 and P3 in the 51 patients accounted for 37.25% (19/51), 41.18% (21/51) and 19.60% (10/51), respectively. According to the diagnostic criteria (WS 257–2006) of China for echinococcosis, the patients of infiltration type, calcification type and liquefaction cavitary type accounted for 66.67% (34/51), 21.57% (11/51) and 11.76% (6/51), respectively. Among the 51 patients, 78.43% (40/51) of the patients had clinical symptoms of biliary tract disease, and 58.82% (30/51) had gallbladder-related complications. The operations were performed on 40 patients, and 77.50% (31/40) of them had the postoperative complications. The results of binary multivariate logistic regression analysis showed that the clinical image classification, the liver segment distribution, size, location and number of lesions of hepatic alveolar echinococcosis were important correlative factors for the occurrence of gallbladder complications in hepatic alveolar echinococcosispatients. Conclusions The incidence of complications related to gallbladder diseases is higher in the children with hepatic alveolar echinococcosis in Qinghai Province, and it has great influence on the operation mode and the occurrence and prognosis of postoperative complications. The early diagnosis and treatment of alveolar echinococcosis in children is particularly important.

ABSTRACT
<p><b>OBJECTIVE</b>To study different effects of Herba Lycopodii (HL) Alcohol Extracted Granule combined methylprednisolone on behavioral changes, brain derived neurotrophic factor (BDNF) expression levels, and N-methyl-D-aspartate (NMDA) receptor levels in rats with spinal cord injury (SCI).</p><p><b>METHODS</b>Male adult SD rats were randomly divided into five groups, i.e., the sham-operation group, the model group, the HL treatment group, the methylprednisolone treatment group, the HL + methylprednisolone treatment group. Rats in the HL treatment group were intragastrically administered with HL at the daily dose of 50 mg/kg for 5 successive days. Rats in the methylprednisolone treatment group were intramuscularly injected with 50 mg/kg methylprednisolone within 8 h after spinal cord contusion, and then the dose of methylprednisolone was reduced for 10 mg/kg for 5 successive days. Rats in the HL + methylprednisolone treatment group received the two methods used for the aforesaid two groups. Basso Beattie and Bresnahan (BBB) score (for hindlimb motor functions) were assessed at day 0, 3, 7, and 28 after operation. At day 13 after SCI, injured spinal T8-10 was taken from 8 rats of each group and stored in liquid nitrogen. The N-methyl-D-aspartate (NMDA) receptor affinity (Kd) and the maximal binding capacity (Bmax) were determined using [3H]MK-801 radioactive ligand assay. Rats' injured spinal cords were taken for immunohistochemical assay at day 28 after SCI. Expression levels of BDNF in the ventral and dorsal horn of the spinal cord were observed.</p><p><b>RESULTS</b>Compared with the sham-operation group, the number of BDNF positive neurons in the ventral and dorsal horn of the spinal cord increased in the model group, Bmax increased (470 ± 34), Kd decreased, and BBB scores decreased at day 3 -28 (all P <0. 05). Compared with the SCI model group, the number of BDNF positive neurons and Kd increased, BBB scores at day 3 -28 increased (P <0. 05) in each medicated group. Bmax was (660 ± 15) in the methylprednisolone treatment group, (646 ± 25) in the HL treatment group, and (510 ± 21) in the HL +methylprednisolone treatment group (P <0. 05). Compared with the methylprednisolone treatment group, the number of BDNF positive neurons and Kd increased, BBB scores at day 7 -28 increased, and Bmax decreased in the HL treatment group and the HL + methylprednisolone treatment group (all P <0. 05). Compard with the HL treatment group, the number of BDNF positive neurons and Kd increased, and Bmax decreased (all P < 0.05).</p><p><b>CONCLUSIONS</b>HL could effectively improve motor functions of handlimbs, increase expression levels of BDNF in the spinal cord, and lessen secondary injury by affecting spinal levels of NMDA receptors. It showed certain therapeutic and protective roles in treating SCI. Its effect was better than that of methylprednisolone with synergism.</p>
