Chinese Journal of Biochemical Pharmaceutics 2014;(2):61-64,67
Objective The stability and other characteristics of the active recombinant human anionic trypsin(hT 2) with site-mutation R 122 L(mhT 2) were investigated. Methods An active human anionic trypsin and its R 122 L mutate were produced with E.coli BL 21(DE 3) and purified with ion-exchange chromatography. The properties of mutant were studied and compared with the wild type. Results The optimal pH for mhT 2 was 7~11. mhT 2 was active over a broad temperature range (4℃~80℃) and owned a little better thermal stability than the wild type. The inhibition of typical metal chelating agent(EDTA), Fe 3+, denaturant, reducer(β-ME) on activity of mhT 2 was the same as the wild type. Michaelis constant Km of mhT 2 was 0.010 mmol/L with BAEE as a substrate, a little lower than wild type. Conclusion Compared with the wild type, the R 122 L site mutate significantly enhanced tolerance to acidic pH、denaturants、reductions and autolysis.

Objective To study cutaneous ultrastructural changes and FERMT1 gene mutations in a patient with Kindler syndrome. Methods Clinical data were collected, and tissue samples obtained from the lesions of poikiloderma were observed by using transmission electron microscopy. Fifteen coding exons and their flanking sequences of the FERMT1 gene were amplified by PCR and DNA sequencing was followed.Results Reduplication of lamina densa was seen between the dermal-epidermal junctions of the lesional skin. The patient was found to be homozygous for a novel splice-site mutation (IVS9 + 1G > A) in FERMT1 gene, and his parents were heterozygous for it. The mutation was undetected in fifty normal control individuals.Conclusions Transmission electron microscopy may serve as an ancillary examination for the diagnosis of Kindler syndrome. The IVS9+1G>A mutation of FERMT1 gene may contribute to the clinical phenotype of Kindler syndrome in this patient.

This article was aimed to study An-shen drug substances of semen ziziphi spinosae and the relationship between index component distribution in vivo and meridian tropism. Intragastric administration of thyroid tablet suspension at the dose of 160 mg·kg-1 was given for 13 days for the establishment of yin deficiency rat model. Elevated plus maze test (EPM) was combined with light/dark box test to evaluate the effect of semen ziziphi spinosae on anxiety behavior among yin deficiency rats. The yin deficiency anxiety model rats' eyeballs were picked for blood at 10, 20, 30, 40, 60, 90, 120, 240 min after intragastric administration of semen ziziphi spinosae decoction. The rats were sacrificed for the collecting of heart, liver, spleen, lungs, kidneys, stomach, brain, large intestine and small intestine and other tissues. HPLC-PDA-ELSD was combined to detect concentrations of spinosin, jujuboside A and jujuboside B in different tissues of rats. Related pharmacokinetic parameters were achieved after processing detected data with DAS 2.0 software. The results showed that compared with the yin deficiency group, semen ziziphi spinosae significantly reduced the rats' abnormal increased food-intake (P < 0.01) and water intake (P < 0.01) within 24 hours; significantly increased the body weight difference before and after treatment (P < 0.01); significantly reduced the kidney coefficient (P < 0.01) and adrenal gland coefficient (P < 0.01); significantly reduced the value of T3 (P < 0.01) and T4 (P < 0.05); significantly increased the value of TSH (P < 0.01). It showed that semen ziziphi spinosae can obviously improve yin deficiency symptoms. It significantly increased the number of open arms entering percentage (P < 0.01), the open arms holding percentage (P < 0.01), and the box through times in light/dark box test (P < 0.01). It showed obvious anti-anxiety effects. The index component distribution in vivo results showed that spinosin and jujuboside A were widely distributed in the heart, liver, spleen, lungs, kidneys, stomach, brain, large intestine, small intestine and other tissues through blood circulation. Jujuboside B was distributed in the blood, stomach, large intestine and small intestine through blood circulation. The order of average concentration of spinosin among tissues was small intestine > stomach > liver > brain > large intestine > spleen > lungs > heart > kidneys. The order of AUC0-t in tissues was small intestine > stomach > liver > large intestine > spleen > brain > heart > kidneys > lungs. The order of average concentration of jujuboside A among tissues was lungs > large intestine > heart > spleen > liver > kidneys > small intestine > stomach > brain. The order of AUC0-t in tissues was lungs > spleen > liver > heart > large intestine > brain > stomach > kidneys > small intestine. The order of average concentration of jujuboside B among tissues was large intestine > small intestine > stomach. The order of AUC0-t in tissues was large intestine > small intestine > stomach. It was concluded that semen ziziphi spinosae can obviously improve yin deficiency symptoms with good anti-anxiety effects. Spinosin and jujuboside A in semen ziziphi spinosae were the drug substances of An-shen effect. They were also the material basis of sweet and sour taste. The spinosin and jujuboside A distribution in vivo of yin deficiency anxiety model rats were close to the meridian tropism of semen ziziphi spinosae.

Retroperitoneal laparoscopic live donor nephrectomy offers an intrinsic advantage over conventional transperitoneal laparoscopic nephrectomy because of the potentially lower risk for early and late donor intraperitoneal complications. Herein we presented our experience performing retroperitoneal laparoscopic live donor nephrectomy in 105 donors. All donor nephrectomy was successful. There were no donor deaths and no conversion to open surgery. Mean operation time was 112 min (range, 70-200 min). Intraoperative blood loss was 10-150 mL with an average of 30 mL. Warm ischemia time was 1.3 to 6 min with an average of 3.1 min. Postoperative retroperitoneal hematoma occurred in only one case and there were no other surgical complications. Donors were discharged from the hospital 5 to 10 days postoperation. Average postoperative hospital stay was 6.4 days. One graft was removed due to acute rejection. Delayed graft function occurred in two recipients but renal function returned to normal within four weeks. The other recipients had normal renal function in two weeks except three recipients in four weeks. We believe that retroperitoneal laparoscopic live donor nephrectomy is safe, reliable, and less invasive.

AIM: To explore the effect of TNF-related apoptosis inducing ligand (TRAIL), a new apoptotic inducing molecule on the biological activity of hepatocarcinoma cell line. METHODS: The expression of membrane binding TRAIL on HepG2 cells was detected by immuno-cytochemistry. Quantity of secretory TRAIL was assayed by ELISA method. The cytotoxicity and apoptosis induced by TRAIL was detected by MTT and TUNEL method, respectively. The telomerase activity of HepG2 cells was detected by TRAP-PCR assay kit. The expression of hTERT, the catalytic subunit of telomerase, was detected by FCM. RESULTS: TRAIL was constitutively expressed on the membrane of HepG2 cell line. Soluble TRAIL was also expressed to a certain degree. Cytotoxicity assay showed that TRAIL significantly inhibited the growth of hepatocarcinoma cells. TUNEL assay indicated that TRAIL induced apoptosis in hepatocarcinoma cells. Detection of telomerase activity showed that TRAIL inhibited telomerase activity and the expression of telomerase catalytic subunit. CONCLUSION: TRAIL is an effective molecule to inhibit the growth of hepatocarcinoma through multiple pathways, such as inducing apoptosis and inhibiting the activity of telomerase.
