Two hundred and eight cases confirmed as tinea pedis were randomized to two groups: group A (n=108) and group B (n=100). Group A was treated with Xiaoxuan Lotion (mainly composed of Radix et Rhizoma Rhei, Herba Artemisiae Scopariae, Cortex Phellodendri, Radix Sophorae Flavescentis, Radix Stemonae, etc.) and group B with miconazole nitrate cream. Two treatment courses were carried out. After one treatment course, 65 (60.2%) cases were cured in group A and 45 (45%) in group B, the difference being significant (P

Objective:To investigate the effects of Chuanxikang decoction(a Chinese herbal medicine)on the amount of IFN-? and IL-5 in bronchoalveolar lavage fluid(BALF) and expression of MMP-9 and TIMP-1 in lung tissue of asthmatic model in guinea pig to explore its mechanism in treatment of bronchial asthma.Methods:A total of 40 guinea pigs were randomly divided into 4 groups:normal control group(A group),asthmatic model group(B group),treatment with dexamethasone(C group) or with Chuanxikang decoction groups(D group),10 guinea pigs in each group.The guinea pig models of asthma were established through injecting ovalbumin(OVA) into the abdominal cavity and inhalation of atomization.The guinea pigs of asthma underwent with different therapy.Amount of IFN-? and IL-5 in BALF and expression of MMP-9 and TIMP-1 in lung tissue were measured by immunotisssuchemical technology.Results:Compared with the normal control group(A group),the concentrations of IFN-? in the BALF was decreased significantly(P

Objective To explore the management of gliomas in pregnant women.Methods We retrospectively analyzed the clinical data in 11 pregnant women with gliomas treated at Xuanwu Hospital of Capital Medical University between January 1989 and December 2012.Results All the patients were first diagnosed with gliomas during pregnancy,including two cases during early pregnancy,four cases during midpregnancy,and five cases during late pregnancy.The main clinical manifestations were dizziness,headache,nausea and vomiting due to intracranial hypertension,accompanied by epilepsy and blurred vision,hearing and speech disorder and other neurological dysfunctions.Among the 11 patients,one received no obstetric treatment,five underwent cesarean section,three had metaphase induced labor,one had induced abortion,and one had spontaneous abortion.Five neonates appeared normal without malformation:four survived,and one with severe asphyxia died.Ten patients underwent neurosurgery,four of them were diagnosed with low-grade gliomas and six were diagnosed with high-grade glioma by pathology.Seven patients received craniotomy after termination of pregnancy,two underwent craniotomy before termination of pregnancy,and one received emergency craniotomy immediately after admission without obstetric treatment because of her critical conditions.Of the ten patients treated with craniotomy,one died after a coma for 50 days,one was lost to follow-up,six received radiotherapy plus chemotherapy,one received chemotherapy alone,and one received neither radiotherapy nor chemotherapy.Among the 11 patients,one patient who underwent cesarean section without craniotomy was lost to follow-up,one patient with low-grade glioma died 50 days after operation,one treated with craniotomy was lost to follow-up,and eight were followed up for four months to three years,among which four survived and four with high-grade glioma died within one year after operation.Conclusion The overall prognosis of glioma patients during pregnancy is poor.It is important to take into account the tumor status of the pregnant women,gestational age,fetal maturity and patient's desire for tocolysis,and weigh the pros and cons,and timely terminate pregnancy and perform neurosurgery.

The mutation of cystic fibrosis transmembrane conductance regulator (CFTR) gene leads to an autosomal recessive genetic disorder cystic fibrosis (CF). The gene therapy for CF using adeno-associated virus (AAV) vectors delivering CFTR gene is restricted by the contents limitation of AAV vectors. In this study the split CFTR genes severed at its regulatory domain were delivered by a dual-vector system with an intein-mediated protein trans-splicing as a technique to investigate the post-translational ligation of CFTR half proteins and its function as a chloride ion channel. A pair of eukaryotic expression vectors was constructed by breaking the human CFTR cDNA before Ser712 codon and fusing with Ssp DnaB intein coding sequences. After co-transfection into baby hamster kidney (BHK) cells followed by transient expression, patch clamps were carried out to record the chloride current of whole-cell and the activity of a single channel, and the ligation of two halves of CFTR was observed by Western blotting. The results showed that the intein-fused half genes co-transfected cells displayed a high whole cell chloride current and activity of a single channel indicating the functional recovery of chloride channel, and an intact CFTR protein band was figured out by CFTR-specific antibodies indicating that intein can efficiently ligate the separately expressed half CFTR proteins. The data demonstrated that protein splicing strategy could be used as a strategy in delivering CFTR gene by two vectors, encouraging our ongoing research program on dual AAV vector system based gene transfer in gene therapy for cystic fibrosis.

We recently demonstrated that an intein-mediated protein splicing can be used to transfer B-domain-deleted FVIII (BDD-FVIII) gene by a dual-vector. In this study, we observed the effect of a variant heavy chain with six potential glycosylation sites of B domain and L303E/F309S mutations in its A1 domain, which were proven to be beneficial for FVIII secretion, on secretion of spliced BDD-FVIII. By transient co-transfection of cultured 293 cells with intein-fused variant heavy chain (DMN6HCIntN) and light chain (IntCLC) genes, the culture supernatant was analyzed quantitatively by ELISA for secreted spliced BDD-FVIII antigen and by a chromogenic assay for bioactivity. The data showed that the amount of spliced BDD-FVIII protein and coagulation activity in culture supernatant from DMN6HCIntN plus IntCLC co-transfected cells were up to (149 +/- 23) ng x mL(-1) and (1.12 +/- 0.14) u x mL(-1) respectively greater than that of intein-fused wild type heavy (HCIntN) and light chain (IntCLC) co-transfected cells [(99 +/- 14) ng x mL(-1) and (0.77 +/- 0.13) u x mL(-1)] indicating that the variant heavy chain is able to improve the secretion of spliced BDD-FVIII and activity. A cellular mechanism-independent BDD-FVIII splicing was also observed. It provided evidence for ongoing animal experiment using intein-mediated dual-AAV vector technology for delivery of the BDD-FVIII genes.

To investigate the improving effect of inter-chain disulfide formation on protein trans-splicing, we introduce a Cys point mutation at Tyr(664) in heavy chain and at Thr(1826) in light chain of B-domain-deleted FVIII (BDD-FVIII). By co-transfection of COS-7 cell with the two Cys mutated chain genes, the intracellular protein splicing, inter-chain disulfide formation, secreted BDD-FVIII and bioactivity in culture supernatant were observed. The data showed that a strengthened spliced BDD-FVIII with an inter-chain disulfide detected by Western blotting and an elevated secretion of spliced BDD-FVIII (128 +/- 24 ng mL(-1)) compared to control (89 +/- 15 ng mL(-1)), assayed by a sandwich ELISA. A Coatest was performed to assay the secretion of bioactivity in culture supernatant and shown a much higher value (0.94 +/- 0.08 u mL(-1)) compared to that of control (0.62 +/- 0.15 u mL(-1)). It suggests that inter-chain disulfide formation could improve protein trans-splicing based dual-vector delivery of BDD-FVIII gene providing experimental evidence for ongoing in vivo study.

ObjectiveTo observe the changes of thyroid hormone and reproductive hormone in post-acute traumatic brain injury(TBI).Methods70 post-acute TBI patients were selected from Beijing Charity Hospital from September 2009 to March 2010. The levels of thyroid stimulating hormone(TSH), triiodothyronine(T3), thyroxine(T4), free triiodothyronine(FT3), free thyroxine (FT4), follicie stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), progesterone (P), and testosterone (T) were measured at 7 a.m. to 8 a.m. on the second day of admisson. According to the reference ranges, the total abnormal rate and the single hormone abnormal rate were calculated. According to the level of hormone, the subjects were divided into the normal group and the abnormal group. The two groups were compared in gender, age, course of disease, duration of coma, basal fracture and scores of Disability Rating Scale (DRS).ResultsThe total abnormal incidence of anterior pituitary hormone was 77.1% in post-acute TBI. The abnormality of reproductive hormones was higher. The duration of coma was related to the reproductive hormone.ConclusionThe abnormal incidence of anterior pituitary hormone occurs frequently in post-acute TBI. The duration of coma is related to the reproductive hormone.
