Tuberous sclerosis complex (TSC) is an involving multiple organs and tissues of the rare autosomal dominant genetic disease.There are various clinical manifestations in patients with TSC and its diagnosis based on clinical characteristics.Diagnostic criteria of TSC include clinical diagnosis and gene diagnosis standard.

Objective To evaluate the value of digital subtraction angiography(DSA) in diagnosis and planning endovascular treatment of cerebrovascular diseases. Methods Thirty-one children suspected with ischemic cerebrovascular diseases were treated by urokinase and dextran after they underwent DSA.Results Twenty-four cases (77%) had cerebrovascular abnormalities. Two cases had arteriovenous malformations, 1 case had posterior communicating artery aneurysm,21 cases had cerebrovascular stenosis or occlusions. Shortly after intervention therapy using urokinase,muscle strength increased by one level in 13 cases,two levels in 3 cases,3 levels in 2 cases and no effect in 4 cases. The total effective rate reached 86%. Seven patients with ischemic stroke achieved 100% recanalization. Conclusion DSA is very important in diagnosis of cerebrovascular stenosis and occlusion.

Objective To study the factor affecting the efficiency of establishment of parthenogenetic stem cells (PESCs)in mice. Methods PESC lines were derived from parthenogenetically activated blastocyst inner cell mass of different mice strains and cultured in different systems.Results The efficiency of establishing the pESC showed no significant difference in hybrid and inbred lines.But the efficiency was increased in culture systems added with ERK inhibitor or knockout serum replacement(KSR).Conclusion The efficiency of establishment of pESC was not directly related with the genetic background of mice but it was closely related to the culture systems.

Tic disorders (TD) is a kind of neuropsychiatric disorders developing during childhood and cha-racterized by tics.In August 2020, the TD Consortium Neurology Group of Chinese Pediatric Society, Chinese Medical Association has developed an English version of Expert Consensus on Diagnosis and Treatment of Tic disorders in children to help improve the diagnosis, treatment and long-term management of TD, as well as international communication.Now the consensus is interpreted as follows, including its pathophysiology, clinical characteristics, diagnosis, comorbidity, treatment and prognosis.

Tuberous sclerosis complex (TSC) is a genetic disorder affecting every organ system, but disease manifestations vary significantly among affected individuals.The diverse and varied presentations and progression can be life-threatening with significant impact on quality of life.The 2012 international Tuberous Sclerosis Complex Consensus Recommendations provide an evidence-based, standardized approach for optimal clinical care provided for individuals with TSC.

Objective To investigate the clinicopathological features of primary hepatocellular carcinoma of the liver(PCCCL)and assess the over-all survival rate of PCCCL after hepatectomy and the association between prognosis and clear cell ratio in PCCCL.Methods The clinicopathological data of 43 patients with PCCCL treated with hepatectomy in our hospital from January 1999 to December 2003 were retrospectively analyzed.Results X2 test showed a positive rate of HCV infection(14.0%)and capsule formation(88.4 0A)in the PCCCL group markedly higher than the positive rate of HCV infection(1.2%)and capsule formation(65.0%)in the CHCC group(P=0.000 and 0.005).Meanwhile,the vascular invasion rate was notably Iower in the PCCCL group(53.4%vs.65.0%),but there were no significant differences between the two groups(P=0.129).Kaplan-Meier method showed that the1-,3-and 5-year survival rates were significantly higher in the PCCCL group than in the CHCC group(81%,53%and 39%vs.76%,46%and 32 0A,P=0.021).The prognosis of patients in the PCCCL group was related to capsule formation.vascular invasion,liver cirrhosis and clear cell ratio.The 1-,3-and 5-year survival rates were markedly higher in the group with higher clear cell ratio (≥75%,subgroup B)than in group with lower clear cell ratio(＜75%,subgroup A)(80 0A,43%and 23%vs.85 0A,77% and 68%,P=0.011).Conclusion The notable clinicopathologicaI features of the patients with PCCCL are higher rates of HCV infection.capsule formation and lower rate of vascular invasion.Their prognosis is better than the patients with CHCC and related with the ratio of clear cell.

ObjectiveTo observe the effect of recombinant human interleukin-11 combined with ciclosporin in treatment of giucocorticoid invalid idiopathic thrombocytopenic purpura.MethodsFrom August 2009 to August 2011,35 cases with glucocorticoid invalid idiopathic thrombocytopenic purpura patients were divided into two groups according to the treatment method:13 cases in control group were treated with ciclosporin and 22 cases in observation group were treated with recombinant human interleukin-11 at basis of above method.The clinical effect and platelet counts between two groups were compared.Results The total effective rate in observation group was 90.9％ (20/22),which was significantly higher than that in control group [53.8％ (7/13)] (P ＜0.05).After treatment,the platelet counts in both two groups were significantly increased [control group:( 112.5 ± 15.4) × 109/t vs.(13.2 ± 1.8 ) × 109/L; observation group:( 132.7 ± 22.3 ) × 109/L vs.(12.9 ± 1.6) × 109/L] (P ＜ 0.05 ).Moreover,the platelet counts after treatment in observation group was significantly more than that in control group (P ＜ 0.05).ConclusionRecombinant human interleukin-11combined with ciclosporin in treatment of glucocorticoid invalid idiopathic thrombocytopenic purpura is a good treatment scheme,which can be applied in clinic.

Objective To summarize the experience of unilateral endonasal transsphenoidal pituitary adeno-ma resection under neuroendoscopy. Methods 48 patients with pituitary adenoma were treated by unilateral en-donasal transsphenoid under neuroendoscopy. During the dissection of the adenoma, attention should be paid to pro-tect pituitary stalk and gland. Results The postoperative MRI detection revealed that the tumor was totally removed in 40(83.3%) cases,subtotally in 6(12.5%) ,and partially in 2(4.2%). All patients were followed up for 10 -36 months. Among the 38 patients with increased hormone level ,24 recovered to normal hormone level postoperatively; 14 were improved evidently;pituitary insufficiency was not found in 38 cases;7 patients have temporary diabetes in-sipidus but the symptom was released in three weeks. Conclusion The surgical treatment of pituitary adenoma by neuroendoscopic unilateral endonasal transsphenoid has its advantage in achieving both complete resection of tumor and sound protection of pituitary stalk and gland. Neuroendoscopic operation offers greater help in improving the pa-tients' quality of survival.

Objective To explore the potential changes of connexin Cx36 in hippocampus and cortical neurons of rats with hyperthermia -induced convulsion.Methods Rats were divided into 2 groups according to the random number table method:normal control group and experimental group.Febrile convulsion model was elicited through im-mersion in warm water.The experimental group was generated following febrile convulsion model:hyperthermia group and febrile convulsion group.Among normal control group,hyperthermia group and febrile convulsion group,western blot analysis and immunofluorescence labeling techniques were used to examine the expression of Cx36 protein in the hippo-campus and cortex area.One -Way ANOVA was used to compare the mean of multiple sample,the LSD test was used to compare the two means.Tamhane′s test was used when variance were uneven.Results The incubation period,seizure duration and temperature were (4.39 ±0.08)min,(5.38 ±0.07)min,(41 .87 ±0.06)℃ after hyperthermia-in-duced convulsion,respectively.Western blot analysis showed that the expression of Cx36 protein in the hippocampus and cortex area decreased gradually after 1 0 times of seizure in normal control group,hyperthermia group and febrile convulsion group,and the febrile convulsion group decreased most obviously.Compared with normal control group and hyperthermia group,respectively,in febrile convulsion group Cx36 expression obviously decreased in the hippocampus and cortex in rats with 1 ,5,1 0 seizure times induced by hyperthermia,and with the increase of number of induced con-vulsion,the expression of Cx36 was significantly decreased in the cortex (0.1 04 ± 0.01 2)and CA1 (0.091 ± 0.01 1 ),CA3 (0.090 ±0.01 1 )and DG (0.092 ±0.01 2)areas of hippocampal neurons compared with the normal control group (0.21 2 ±0.01 7,0.1 67 ±0.01 3,0.1 59 ±0.01 4,0.1 71 ±0.01 3)and the hyperthermia group (0.1 89 ± 0.006,0.1 44 ±0.008,0.1 29 ±0.005,0.1 65 ±0.01 1 )(all P <0.05).Furthermore,the extent of reduction in Cx36 expression seemed to correlate with the number of seizures.Conclusion With the increase of thermal seizure frequen-cy,Cx36 expression of rats was decreased obviously which may lower convulsion threshold and lead to recurrent seizures.
