A growing body of evidence has indicated the important role of autophagy receptors in directing ubiquitinated or non-ubiquitinated cargos towards autophagy. Autophagy receptors bind to LC3 (microtubule-associated protein 1 light chain 3) on phagophore and autophagosome membranes, and recognize signals on cargoes in the delivery system of autophagy. However, the diverse domains in the receptor structures determine that their roles would never be limited to autophagy. Up to date, increasing numbers of the receptor proteins have been demonstrated to serve as a molecular link or switch participating in autophagic degradation, apoptosis or cell survival signals. Here, we highlight the non-autophagic roles of these receptor proteins to draw attention to this growing research topic.

OBJECTIVETo investigate the effcacy of the staple fixation for the treatment of hamate metacarpal joint injury.

METHODSFrom May 2009 to November 2012,16 patients with hamate metacarpal joint injury were treated with staple fixation including 10 males and 6 females with an average age of 33.6 years old ranging from 21 to 57 years. Among them, 11 cases were on the fourth or fifth metacarpal base dislocation without fractures, 5 cases were the fourth or fifth metacarpal base dislocation with avulsion fractures of the back of hamatum. Regular X-ray review was used to observe the fracture healing, joint replacement and position of staple fixation. The function of carpometacarpal joint and metacarpophalangeal joint were evaluated according to ASIA (TAM) system evaluation method.

RESULTSAll incision were healed well with no infection. All patients were followed up from 16 to 24 months with an average of (10.0 +/- 2.7) months. No dislocation recurred, the position of internal fixator was good,no broken nail and screw withdrawal were occurred. Five patients with avulsion fracture of the back of hamatum achieved bone healing. The function of carpometacarpal joint and metacarpophalangeal was excellent in 10 cases,good in 5 cases, moderate in 1 case.

CONCLUSIONThe application of the staple for the treatment of hamatometacarpal joint injury has the advantages of simple operation, small trauma, reliable fixation, early postoperative function exercise and other advantages, which is the ideal operation mode for hamatometacarpal joint injury.

Objective To determine the effect of iron deficiency on hemoglobin A2(HbA2) expression in patients with β-thalassemia.Methods The participants were recruited from the out-patient clinics of the Pediatrics Department and Obstetrics Department of Affiliated Hospital of Guilin Medical College and from some β-thalassemia major families.Blood samples from the participants were used for blood smear tests and hemoglobin electrophoresis and to analyze serum ferritin (SF),3 alpha-globin gene deletions,and 17 beta-globin point mutations.Results Of the 408 individuals,304 were assigned to group A (normal controls),26 to group B (iron deficiency),56 to group C (β-thalassemia),and 22 to group D (β-thalassemia combined with iron deficiency). The results for the comparison of the mean HbA2 values among pairs of groups were as follows: group A vs group B,q=5.074 7,P<0.05; group A vs group C,q=37.650 8,P<0.05; group A vs group D,q=16.043 0,P<0.05;group C vs group D,q=7.682 9,P<0.05; Group B vs group D,q=15.806 6,P<0.05. There were no significant correlation between SF and HbA2 in all 4 groups.Conclusions Iron deficiency decreased the HbA2 level in both controls and individuals with β-thalassemia. HbA2 levels decreased significantly in individuals with both β-thalassemia and iron deficiency as compared with β-thalassemia group alone. However,they remained significantly higher than both the control and iron-deficient groups. Therefore,the elevation of HbA2 could be used to diagnose β-thalassemia reliably even in the presence of iron deficiency.

Nerve growth factor is one of the most important factors playing an important role in regulating the growth, development and survival of the neuron. The purified NGF from human placenta has been reported, the tissue from which can be isolated the NGF is very limited. It is important for basic research and clinic application to expression hNGF by genetic engineering. By polymerase chain reaction,gene fragment encoding the mature part of ?-NGF was amplified using the DNA of human placenta as template. The fragment was sequenced and inserted into expression vector pET-15b, and the recombinant expression vector pET15b-NGF was transformed into E.coli BL21(DE3)pLysS. After inducing with IPTG the NGF was higher expressed up to 25% of the total cell proteins. The expression product was purified with metal chelate affinity chromatography on Ni-IDA agarose under denaturing condition. The purity of rNGF was higher than 90% and yield of rNGF was 4.56mg/L expressing bacteria. SDS-PAGE revealed the NGF expression product had a Mr 16kDa. Western-blot displayed the recombinant product had strong immunological activity with rabbit anti-human ?-NGF polyclonic antibodies. The expression products were dealed with solubilizing inclusion bodies and refolding protein. The test of nerve fiber growth of chicken embryo DRG neurons displayed rNGF had biological activity.

Objective To evaluate the feasibility and initial experience of laparoscopic pyelolithoto- my within renal sinus.Methods A total of 19 patients(14 men and 5 women)of nephrolithiasis on 21 sides underwent laparoscopic pyelolithotomy within renal sinus.Of them,9 cases with other upper urinary tract diseases were treated by laparoseopic pyelolithotomy at the same time.The patient age ranged from 16 to 67 years(mean,41 years).The calculi were 1.2 to 3.5 cm in diameter,and were found on the right side in 11 cases,left side in 6,and both sides in 2.Five cases concomitantly had ureteral calculi;of them,1 had bi- lateral ureter calculi with ipsilateral steinstrasse,2 had pyelic polyp(1 with giant hydronephrosis after open ureterolithotomy),and 1 had giant bydronephrosis with pyelolithiasis during pregnancy with double-J tube drainage.Twelve cases(13 sides)had experienced unsuccessful extracorporeal shock wave lithotripsy,and 1 failed with minimally invasive percutaneous nephrolithotomy.Results The procedure was successful in all the 19 cases.The operative time ranged from 75 to 240 rain(mean,115 rain).The intraoperative blood loss ranged from 30 to 100ml(mean,50 ml).One case experienced 5-d urine leakage,and was spontaneously cured.The hospital stay was 5-9 d(mean,6 d).Double-J tube drainage was 4-6 weeks.During the follow- up(3-36 months),KUB and IVU showed no upper urinary tract stricture and no residual stones except for 1 stone of 0.7 cm in the renal lower calyx in 1 case.The kidney function was improved in all cases.Con- clusions Laparoscopic pyelolithotomy is new and minimally invasive alternative approach for renal calculi. With this procedure the urinary tract complications can be treated concomitantly,thus it can partially replace open surgery.
