Since the first intein was found, more and more attenti on were paid on it. It not only enrichs the content of the process that the gene transfers its information but also can be used in protein purification. The rec ent advance in the sequence characteristic, transfer, evolution and the mechanis m of splicing of intein was summarized.

Adenosine receptors (AR) play an important role in the regulation processes for body temperature and vigilance states. During our previous studies, we noticed that aminophylline (a non-selective, blood-brain-barrier penetrably AR antagonist) could attenuate the effects of YZG-330 [(2R,3S,4R,5R)-2-(hydroxymethyl-5-(6-(((R)-1-phenylpropyl)amino)-9H-purin-9-yl)tetrahydrofuran-3, 4-diol] on lowering the body temperature. Hereby, we focused ourselves on the character of thermal regulation effect of YZG-330 in mice and tried to specify the receptor subtype via giving typical adenosine receptor antagonists. The results showed that both of the magnitude and lasting time of the effect that YZG-330 played on decreasing body temperature are in a dose-dependent manner: within the next 3 hour after intragastric administration (ig) of 0.25, 1 or 4 mg . kg-1 YZG-330, the extreme values on body temperature decreasing were (1.2 ± 0.3) °C, (3.6 ± 0.4) °C (P<0.001) and (7.4±0.5) °C (P<0.001), separately; whereas the duration that body temperature below 34 °C were 0, (10±5) and (153±4) min, separately. Adenosine A1 receptor (A1R) antagonist (DPCPX) could effectively reverse YZG-330's effect on decreasing body temperature, with intraperitoneal administration of DPCPX (5 mg . kg-1) 20 min prior than YZG-330 (4 mg.kg-1, ig), the extreme value on body temperature decreasing was (3.5 ± 0.7) °C (P<0.001), the duration that body temperature below 34 °C was (8±6) min (P<0.001). However, adenosine A2a receptor antagonist, SCH-58261, did not show any influence on the effects of YZG-330 at all. Combined with the fact that 8-SPT (a non-selective, blood-brain-barrier impenetrably AR antagonist) did not reverse the effect of YZG-330, we come to the conclusion that central-adenosine A, receptor plays a significant role on the thermal regulation effect of YZG-330.

OBJECTIVETo study the numbers and locations of spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient under the laparoscope.
METHODSFifty-seven varicocele patients received laparoscopic ligation of spermatic veins, during which we recorded the numbers and observed the locations of spermatic veins, testicular arteries, and spermatic lymphatic vessels.
RESULTSDuring the surgery, we identified 3.3 ± 1.2 spermatic veins, 1.4 ± 0.9 testicular arteries, and 4.3 ± 1.1 spermatic lymphatic vessels. No statistically significant differences were observed between the two side in the numbers of the spermatic veins, testicular arteries and spermatic lymphatic vessels (P > 0.05). The testicular arteries were seen on the exterior of the spermatic veins and winding around them, while the spermatic lymphatic vessels mostly between the veins.
CONCLUSIONThe spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient have their specific anatomic characteristics. Laparoscopic identification of these vessels may contribute to the surgical treatment of varicocele.

OBJECTIVERadial corrective osteotomy is an established but challenging treatment for distal radial malunion. There is an ongoing discussion about whether an opening or closing-wedge osteotomy between should employed. The purpose of the present study was to retrospectively compare the clinical and radio graphic results between conventional opening-wedge osteotomy and closing-wedge technique.
METHODSFrom January 2004 and December 2012,42 patients with extra-articular distal radial malunion were managed with corrective osteotomy and were followed for a minimum of one year. Twenty-two patients (5 males and 17 females, ranging in age from 25 to 75 years old) were managed with radial opening-wedge osteotomy and implanting of interpositional bone graft or bone-graft substitute, and twenty patients (4 males and 16 females, ranging in age from 19 to 79 years) were managed with simultaneous radial closing-wedge and ulnar shortening osteotomy without bone graft. The selection of the surgical procedure was determined by the surgeon. Each patient was evaluated on the basis of objective radio graphic measurements, and functional outcomes were determined on the basis of clinical examinations, including range of wrist motion, grip strength, pain-rating score, Mayo wrist score, and Disabilities of the Arm, Shoulder and Hand (DASH) score.
RESULTSThe mean duration of follow-up was 36 months (ranged, 12 to 101 months) for the opening-wedge cohort and 28 months (ranged, 12 to 87 months) for the closing-wedge cohort. The two techniques were comparable in terms of complications. Post-operative volar tilt and ulnar variance were improved significantly in each cohort. The ulnar variance was more frequently restored to within defined criteria (22.5 to 0.5 mm) in the closing-wedge cohort than that in the opening-wedge cohort. The post-operative mean extension-flexion are of the wrist and Mayo wrist score were significantly better in the closing-wedge cohort. Differences in the pronation-supination arc, grip strength, pain-rating score, and DASH scores between these two cohorts were not significant.
CONCLUSIONThe closing wedge osteotomy technique is an effective reconstructive procedure for the treatment of extra-articular distal radial malunion. It is significantly better than the opening-wedge osteotomy technique in terms of the restoration of ulnar variance, the extension-flexion arc of wrist motion, and the Mayo wrist score.

This research was to study the regulation of intravenous administration of human umbilical cord blood mesenchymal stem cells (HUCBMSCs) on secretion of neural specific protein in rats after traumatic brain injury (TBI), and to explore its mechanisms promoting the recovery of neurological function. The TBI models of rats were established. We then injected HUCBMSCs, labelled by Brdu (5-bromo-2-deoxyuridine), into the TBI rats via the tail vein using modified Feeney free-falling method. The levels of neural biochemical indicators (serum S100β protein, NSE, LDH, CK) of rats were detected in shamed group, injury group and HUCBMSCs-transplanted group. And the morphological changes of brain tissue of rats in the three groups were observed by using HE staining under light microscope. During the whole experiment no immunosuppressant was used for the four groups. From the research, transplant-related death of the rats was not found in transplantation group. In the injury group, rises were found in contents of serum S100β protein, NSE, LDH, CK in the early stage after the rats were injured, which were much higher than those in shamed group at correspondent time point (P < 0.01). In HUCBMSCs-transplanted group, although these biochemistry indexes were found rising for a short period in the early stage, along with the time, these indexes were obviously lower than in those injury group (P < 0.05). Under light microscopy pathological changes of rats in HUCBMSCs-transplanted group were much slighter than those in injury group. It was well concluded that in the situation of no immuno-suppressants, the intravenous-injected HUCBMSCs could reduce the secretion of serum S100β protein, NSE, LDH, CK, promote the repair of tissue injury effectively, and promote the functional recovery of neurons.
