Objective To study the subependymal giant cell astrocytoma (SEGA) in detail, on its clinical manifestations, imaging characteristics, pathological subtypes, surgical treatment and prognosis. Methods Five patients with SEGA proved by surgery and pathology were analyzed retrospectively on their clinical manifestations, treatment and prognosis. Results Tuberous sclerosis complex (TSC) combined with SEGA, an autosomal dominant inherited disease, mostly occurred in children. The typical clinical feature was named as Vogt tri-symptoms-sebaceous adenoma, hypophrenia and epilepsy. Because most of tumors were found at the foramcn of Monro, obstructive hydrocephaluseasily occurred due to the obstruction of foramen of Monro and the third ventricle. Five tumors were totally removed by microsurgery without any postoperative complications. No patients received chemotherapy and radiotherapy. Follow-up between 1 and 8 years indicated no recurrence, and all clinical symptoms of these 5 patients were disappeared after operation. Conclusions SEGA belongs to the low-grade intracranial tumors, which has a more satisfied outcome with a low recurrence rate. The major therapy of SEGA is total resection of the tumor by microsurgery, and it has no need to give chemoand radiotherapy after operation.

Based on variation of Pinus massoniana families, heritablility and correlation analysis, the contents of shikimic acid and procyanidine (heritability 0.90, 0.70), dry weight of single branch (heritability 0.60) and and leaf length (heritability 0.46) were screened out as quality, yield and harvest cost traits of Folium Pini, respectively. For the different medicinal application of Folium Pini, varied methods were chosen to estimate weight and construct index equation. Weight adjustment based.on equal emphasis were used as economic weight determining method to select the best families, and the index (accuracy 0. 936 4 and heritability 0. 881 6) obtained was a little better than that obtained by equal emphasis, and much better than that by restricted index. The superior families selected with adjustment weight and equal emphasis were No. 46, 43 and 28. Partial regression were used as economic weight determining method to select the best families,and the index obtained had the highest accuracy (0.941 5) , index heritability (0. 889 9) and the genetic gain of shikimic acid content. The superior families selected with this method were No. 46, 27 and 47. No. 46 was the best families with maximal economic benefit. Our study indicated that suitable method for estimate weight and construct index equation can be applied for better accuracy of superior families selection of P. massoniana.

OBJECTIVETo summarize the clinical application result of the selective nerve root blocks in limited operation of the lumbar spine.

METHODSFrom January 2008 to October 2012,68 patients with lumbar spinal canal stenosis with multiple levels were underwent the selective nerve root blocks in limited operation of the lumbar spine,including 47 males and 21 females with an average age of 56 years old ranging from 45 to 80. After never roots blocks,64 cases were positive for limited operation of the lumbar spine; the other 4 cases were negative and abort the operation.

RESULTSThe nerve roots block operation smoothly and no complications related to the nerve roots block occurred. There was no neurologic injury complication in this study. Follow-up period ranged from 16 to 45 months postoperatively (means, 32 months). The recovery effect was calculated with Macnab scores, the result was excellent in 44 cases, good in 18 cases, poor in 1.

CONCLUSIONOperative treatment for lumbar spinal canal stenosis with multiple levels is focused on the areas causing symptomate neural compression rather than prophylactic decompression at areas of nonsymptomatic disease. Application of selective nerve root blocks can accurately judge the responsible vertebral body and pain source and improve the curative effect of limited operation of the lumbar spine

The direct acting substances of Cuscuta chinensis in vivo were preliminarily identified through the correlation analysis of "metabolites-effect identification" model. The ovariectomized female rats were i.g administered with 95% ethanol extract part, 40% ethanol elution part and n-butanol extract part of Cuscuta chinensis. The serum fingerprints of different parts and times of administration were established by UPLC/Q-TOF-MS. At the same time, serum estradiol (E₂), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels were detected. Bivariate correlation analysis and grey correlation analysis were used to screen estrogenic components. The results showed that nine direct acting substances in vivo highly related to estrogen effect were found in the drug containing serum, which were hyperoside, astragalin, methyl quercetin glucuronide, quercetin-diglucuronide, quercetin, apigenin, isoquercitrin, kaempferol glucuronide and kaempferol. We can preliminarily screen out the direct acting substance of estrogen effect of Cuscuta chinensis in vivo based on the research idea of serum spectrum effect correlation. It provides a reliable basis for revealing the estrogeneffective substances of Cuscuta chinensis and confirming the quality markers. This experiment was approved by Harbin University of Commerce Ethics Committees (Approval No. HSDU2020-065).

OBJECTIVETo summarize the clinical application results of the repair soft tissue defect in contralateral leg with a cross-leg soleus muscle flap pedicle transplantation.

METHODSFrom January 2008 to January 2013, 8 patients with soft-tissue defect in lower leg underwent reconstruction with a cross-leg soleus muscle flap pedicle transplantation (without microvascular anastomoses). There were 7 males and 1 female, aged from 20 to 49 years old with an average of 31.8 years. The operative time after injury was from 2 to 8 weeks with the mean of 46 days. The soleus muscle flap was transposed across to the contralateral leg defect area, then immediate to perform the coverage of the muscle flaps by a meshed split-thickness skin graft. The donor site was closed directly.

RESULTSAll the muscle flaps had survived completely. In one case, recipient area edge had a less exudate from drainage hole everyday, the incision spontaneously was healed after 2 week's changing dressing. Follow-up period ranged form 1.5 to 4 years with an average of 2.5 years postoperatively. The tibia and fibula fractures were healed well. A good contour was achieved at the recipient area. According to LEM standard, 2 cases got excellent results, 5 good and 1 fair.

CONCLUSIONSoleus flap pedicle transplantation is very suitable to repair the soft tissue defect of the injuried leg only one main blood vessel, and can reduce the damage of donor area.

Objective To summarize the clinical experience of standard piggyback liver transplantation(SPBLT) and modified piggy-back liver transplantation(MPBLT) in the treatment of Wilson′s disease(WD).Methods The clinical records of 29 cases of WD who underwent piggyback liver transplantation over the recent 12 years were analyzed retrospestively.Among them,there were 22 male and 7 female patients,with 6cases aged 8-14y and 23 cases aged 24-37y,who underwent liver transplantation because of chronic advanced liver disease(18cases),fulminant hepatic failure(2 cases),or with normal liver function(9 case),and among them,24 cases showed neurological dysfunction.The modes of operation included SPBLT(13 cases) and MPBLT(16 cases).Results The patients were followed up for 1 month-12 years with the median follow-up time of 47 months.Four patients died in the perioperative period,of which 2 died of hepatic failure due to obstruction of hepatic venous return after SPBLT,and 2 died of hepatic artery thrombosis and bile leakage combined with severe infection.The recipient survival rate at 1 year and 3 years was 86% and 79% respectively.One patient has survived for 12 years.All the levels of serum copper and copper-protein recovered to normal in four weeks post-operatively.Neurological symptoms improved in varying degrees after operation.Conclusions WD patients who undergo PBLT can expect a satisfactory clinical outcome and a good quality of life,and MPBLT can effectively reduce the complications of operation and improve the operation survival rate.
