The epileptic eye and head movements during epileptic seizures may be much more complicated thanpeople originally understood, which can be ipsilateral or contralateral to the electroencephalographyfocus. Here, we describe a male patient with drug resistant focal seizures associated with a directionalseparation between head and eye movement before evolving into generalized tonic-clonic seizure.His contralateral head leading turning showed forced, sustained, and unnatural features companiedby ipsilateral eye staring. Stereoeletroencephalography monitoring was performed, and 4 habitualseizures were recorded over 5 days. Three seizures showed left head leading turning and generalizedtonic-clonic seizure, and only one showed dizziness and ringing in the ears. All the seizures showedthat the ictal onset contacts were located in the posterior inferior temporal sulcus which borders onthe anterolateral part of medial superior temporal area. The patient underwent a resection includingtemporooccipital region, and the histopathology showed focal cortical dysplasia type Ic. He has beenseizure free for two years after operation. The scores of the intelligence and memory quotient improvedhalf year after operation.

OBJECTIVETo investigate the incidence of hot spot mutation of PDS gene by genetic screening testing method in Chifeng City, Inner Mongolia. The feasibility and effectiveness of genetic screening method in finding enlarged vestibular aqueduct syndrome were confirmed by temporal bone CT scan.
METHODSDNA were extracted from peripheral blood of 141 students of Chifeng Deaf and Dumb school. PDS IVS7-2 A-G mutation, the most common PDS mutation in Chinese population, was analyzed by direct sequencing for PDS exon 7, exon 8 with intron 7. The individuals found with homozygous or heterozygous PDS IVS7-2 A-G mutation were given further temporal CT scan, ultrasound scan of thyroid and thyroid hormone assays. The results of PDS genetic screening and temporal bone CT scan were compared with each other.
RESULTSThe sequencing results revealed twenty cases carrying PDS IVS7-2 A-G mutation, of whom nine cases were homozygous mutation and eleven cases were heterozygous mutation. Eighteen cases underwent temporal bone CT scan except two cases that left the school due to other health problem. Sixteen cases were confirmed to be enlarged vestibular aqueduct syndrome (EVAS) by CT scan and the shape and function of thyroid were clinically normal by ultrasound scan of thyroid and thyroid hormone assays, respectively.
CONCLUSIONSThe patients suffered from EVAS can be diagnosed by the screening for the PDS hot spot mutation which has unique advantage in epidemiologic study in large scale deaf population. The preliminary data of this study suggested relatively high incidence of EVAS in Chifeng area.

ObjectiveTo investigate whether phosphodiesterase (PDE) 5 inhibitors sildenafil (SIL) or LW1646 prevented renal interstitial fibrosis induced by unilateral ureteral obstruction (UUO). MethodsMale C57BL/6 mice were randomly divided into four groups (n =6), namely the Sham group, 7UUO group, 7UUO+SIL group and 7UUO+LW1646 group. Sildenafil (SIL) or LW1646, or vehicle was administered 1 hour before surgery, and the mice were continuously treated once daily (i. g., 50 mg/kg) for 7 days. The obstructed kidneys were harvested on day 7. Hematoxylin-eosin (HE) and Masson’s staining was used to examine renal histology. Immunoblotting and RT-qPCR were used to detect the expression levels of protein and mRNA for fibrosis, apoptosis, endoplasmic reticulum (ER) stress, autophagy, and pro-fibrotic factors. Human proximal tubule epithelial cells (HK-2) were treated with TGF-β1 for 48 hours or tunicamycin for 24 hours, respectively, to evaluate whether cyclic guanosine monophosphate (cGMP) or PDE5 inhibitors prevents ER stress and pro-fibrotic responses. ResultsAt the 7th days after UUO, the body weight of the mice showed a significant decrease (P< 0.000 1) compared with that in the sham group. The obstructed kidneys showed a significant tubular dilation and interstitial inflammation. The levels of protein and mRNA expression in apoptosis, ER stress, autophagy-related protein and pro-fibrotic factors were also markedly increased in UUO mice (P <0.05). In contrast, SIL or LW1646 treatment was associated with attenuated tubular dilation, infiltration of inflammatory cells and collagen content in the obstructed kidney of the mice. The protein and mRNA expression levels of renal TGF-β1 were markedly decreased, and the protein expression levels of apoptosis, endoplasmic reticulum stress, and autophagy markers were also significantly downregulated by PDE5 inhibitors. In HK-2 cells, TGF-β1 induced increased expression levels of fibronectin and BiP, which was at least partially reversed by cGMP, a product of PDE inhibition. Additionally, PDE5 inhibitors were found to modulate aberrant levels of autophagy and apoptosis. ConclusionIn conclusion, PDE5 inhibitors, in particular, LW1646, can alleviate the progression of fibrosis by improving ER stress, apoptosis and autophagy as well as downregulating protein and mRNA expression of TGF-β1.

Tripterygium Glycosides Tablets has good anti-inflammatory and immunomodulatory activities,but its reproductive damage is significant. Previous studies of the research group have found that Cuscutae Semen flavonoids can improve spermatogenic cell damage caused by Tripterygium Glycosides Tablets by regulating spermatogenic cell cycle,apoptosis and related protein expression,but the mechanism of action at the gene level is still unclear. In this study,Illumina high-throughput sequencing platform was applied in transcriptional sequencing of spermatogenic cells of rats after the intervention of Cuscutae Semen flavonoids and Tripterygium Glycosides Tablets. Differentially expressed genes were screened out and the GO enrichment and KEGG pathway analysis of differentially expressed genes were conducted to explore the mechanism of Cuscutae Semen flavonoids in improving reproductive injury caused by Tripterygium Glycosides Tablets. The results showed that 794 up-regulated genes and 491 down-regulated genes were screened in Tripterygium Glycosides Tablets group compared with the blank group. Compared with Tripterygium Glycosides Tablets,440 up-regulated genes and 784 down-regulated genes were screened in the Cuscutae Semen flavonoids+Tripterygium Glycosides Tablets group. Among them,the gene closely related to reproductive function is DNMT3 L. Analysis of GO function and KEGG signaling pathway enrichment showed that the above differentially expressed genes were mainly enriched in cell,cell process,catalytic activity,binding,ovarian steroid synthesis,thyroid hormone and other functions and pathways. The thyroid hormone signaling pathway was the common enrichment pathway of the two control groups. In a word,Cuscutae Semen flavonoids has a good treatment effect on male reproductive damage caused by Tripterygium Glycosides Tablets. The mechanism may be closely related to up-regulation of DNMT3 L genes and intervention of thyroid hormone signaling pathway. At the same time,the discovery of many different genes provides valuable information for study on the mechanism of Cuscutae Semen flavonoids and Tripterygium Glycosides Tablets compatibility decreasing toxicity and increasing efficiency.

This study investigated the effect of multi-glycosides of Tripterygium wilfordii(GTW) on renal injury in diabetic kidney disease(DKD) rats through Nod-like receptor protein 3(NLRP3)/cysteine-aspartic acid protease-1(caspase-1)/gsdermin D(GSDMD) pyroptosis pathway and the mechanism. To be specific, a total of 40 male SD rats were randomized into the normal group(n=8) and modeling group(n=34). In the modeling group, a high-sugar and high-fat diet and one-time intraperitoneal injection of streptozotocin(STZ) were used to induce DKD in rats. After successful modeling, they were randomly classified into model group, valsartan(Diovan) group, and GTW group. Normal group and model group were given normal saline, and the valsartan group and GTW group received(ig) valsartan and GTW, respectively, for 6 weeks. Blood urea nitrogen(BUN), serum creatinine(Scr), alanine ami-notransferase(ALT), albumin(ALB), and 24 hours urinary total protein(24 h-UTP) were determined by biochemical tests. The pathological changes of renal tissue were observed based on hematoxylin and eosin(HE) staining. Serum levels of interleukin-1β(IL-1β) and interleukin-18(IL-18) were detected by enzyme-linked immunosorbent assay(ELISA). Western blot was used to detect the expression of pyroptosis pathway-related proteins in renal tissue, and RT-PCR to determine the expression of pyroptosis pathway-related genes in renal tissue. Compared with the normal group, the model group showed high levels of BUN, Scr, ALT, and 24 h-UTP and serum levels of IL-1β and IL-18(P<0.01), low level of ALB(P<0.01), severe pathological damage to kidney, and high protein and mRNA levels of NLRP3, caspase-1, and GSDMD in renal tissue(P<0.01). Compared with the model group, valsartan group and GTW group had low levels of BUN, Scr, ALT, and 24 h-UTP and serum levels of IL-1β and IL-18(P<0.01), high level of ALB(P<0.01), alleviation of the pathological damage to the kidney, and low protein and mRNA levels of NLRP3, caspase-1, and GSDMD in renal tissue(P<0.01 or P<0.05). GTW may inhibit pyroptosis by decreasing the expression of NLRP3/caspase-1/GSDMD in renal tissue, thereby relieving the inflammatory response of DKD rats and the pathological injury of kidney.

To preliminarily investigate the effect of Tripterygium Glycosides Tablets( TGT) combined with traditional Chinese medicine( TCM) on the fertility and female menstruation on persons who have took during childhood. The children with henoch-schonlein purpura( HSP) or henoch-schonlein purpura nephritis( HSPN) who treated with TGT under 18 years old and now older than 18 years old( including 18 years old) during January 1998 to December 2010 were selected in our research. The content of follow-up visit included marriage,marriage age,fertility and child health; and unmarried female patients were asked whether they had menstrual abnormalities. The data of the unmarried female patients,including age,clinical classification,TCM syndrome type,initial dose and other related factors that may affect menstrual cycle,was analyzed by using binary logistic regression analysis. A total of 195 patients who met the criteria were followed up in this study,and 26 patients married for more than 1 year. Among the 26 married patients,1 HSP patient had no birth planning due to rheumatoid arthritis,and the remaining 25 patients all had given birth or were pregnant. The 169 unmarried patients included 89 female patients. Among the 89 female patients,4 cases refused to tell the menstrual situations,72 cases had normal menstruation( 84. 7%),13 cases had abnormal menstruation( 15. 3%),and there was no case of amenorrhea. Logistic regression analysis results showed that the age,clinical classification,TCM syndrome type and initial dose had no correlation with abnormal menstruation. Our results demonstrated that TGT has no effect on adulthood fertility among patients who took TGT combined with traditional Chinese medicine during childhood.

Objective: To explore the effect of perioperative chemotherapy on the prognosis of gastric cancer patients under real-world condition. Methods: A retrospective cohort study was carried out. Real world data of gastric cancer patients receiving perioperative chemotherapy and surgery + adjuvant chemotherapy in 33 domestic hospitals from January 1, 2014 to January 31, 2016 were collected. Inclusion criteria: (1) gastric adenocarcinoma was confirmed by histopathology, and clinical stage was cT2-4aN0-3M0 (AJCC 8th edition); (2) D2 radical gastric cancer surgery was performed; (3) at least one cycle of neoadjuvant chemotherapy (NAC) was completed; (4) at least 4 cycles of adjuvant chemotherapy (AC) [SOX (S-1+oxaliplatin) or CapeOX (capecitabine + oxaliplatin)] were completed. Exclusion criteria: (1) complicated with other malignant tumors; (2) radiotherapy received; (3) patients with incomplete data. The enrolled patients who received neoadjuvant chemotherapy and adjuvant chemotherapy were included in the perioperative chemotherapy group, and those who received only postoperative adjuvant chemotherapy were included in the surgery + adjuvant chemotherapy group. Propensity score matching (PSM) method was used to control selection bias. The primary outcome were overall survival (OS) and progression-free survival (PFS) after PSM. OS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the last effective follow-up or death. PFS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the first imaging diagnosis of tumor progression or death. The Kaplan-Meier method was used to estimate the survival rate, and the Cox proportional hazards model was used to evaluate the independent effect of perioperative chemo therapy on OS and PFS. Results: 2 045 cases were included, including 1 293 cases in the surgery+adjuvant chemotherapy group and 752 cases in the perioperative chemotherapy group. After PSM, 492 pairs were included in the analysis. There were no statistically significant differences in gender, age, body mass index, tumor stage before treatment, and tumor location between the two groups (all P>0.05). Compared with the surgery + adjuvant chemotherapy group, patients in the perioperative chemotherapy group had higher proportion of total gastrectomy (χ(2)=40.526, P<0.001), smaller maximum tumor diameter (t=3.969, P<0.001), less number of metastatic lymph nodes (t=1.343, P<0.001), lower ratio of vessel invasion (χ(2)=11.897, P=0.001) and nerve invasion (χ(2)=12.338, P<0.001). In the perioperative chemotherapy group and surgery + adjuvant chemotherapy group, 24 cases (4.9%) and 17 cases (3.4%) developed postoperative complications, respectively, and no significant difference was found between two groups (χ(2)=0.815, P=0.367). The median OS of the perioperative chemotherapy group was longer than that of the surgery + adjuvant chemotherapy group (65 months vs. 45 months, HR: 0.74, 95% CI: 0.62-0.89, P=0.001); the median PFS of the perioperative chemotherapy group was also longer than that of the surgery+adjuvant chemotherapy group (56 months vs. 36 months, HR=0.72, 95% CI:0.61-0.85, P<0.001). The forest plot results of subgroup analysis showed that both men and women could benefit from perioperative chemotherapy (all P<0.05); patients over 45 years of age (P<0.05) and with normal body mass (P<0.01) could benefit significantly; patients with cTNM stage II and III presented a trend of benefit or could benefit significantly (P<0.05); patients with signet ring cell carcinoma benefited little (P>0.05); tumors in the gastric body and gastric antrum benefited more significantly (P<0.05). Conclusion: Perioperative chemotherapy can improve the prognosis of gastric cancer patients.
