Objective To discuss the feasibility and safety of tension-free mesh plug hernioplasty under local anesthesia in out-patient clinic.Methods Tension-free mesh plug hernioplasty under local anesthesia was performed in 65 cases of unilateral inguinal hernia in out-patient clinic from April 2003 to May 2005.There were 56 cases of indirect inguinal hernia(including 1 case of recurrent hernia) and 9 cases of direct hernia.Results The hernioplasty was successfully completed in all the 65 cases,with good anesthetic results registered.The operation time was 20~65 min(mean,32 min),and the length of clinic stay,3~20 h(mean,(4.8 h)).Incisional fat liquefaction occurred in 1 case.Follow-up visits for 2~24 months(mean,9.5 months) found no recurrence or testicular atrophy.Conclusions Tension-free mesh plug hernioplasty under local anesthesia is a safe,reliable,and cost-effective out-patient procedure for patients with type Ⅱ~Ⅲ unilateral inguinal hernia.

Generalized epilepsy with febrile seizures plus(GEFS+)is a familial in herited epileptic syndrome characterized by phenotypic heterogeneity from the mi lder febrile seizures to the severest epileptic encephalopathy such as severe my oclonic epilepsy in infancy(SMEI).GEFS+ is a disorder with a genetic heterogen eity.Molecular genetics have revealed that four genes are associated with the p athogenesis of GEFS+.These include mutations in genes encoding subunits of neur onal voltage-gated sodium channels(SCN1A,SCN1B,SCN2A)and ?2 subunit of the gamma amino-butyric acid(GABA)A receptor(GABRG2).These genes have be en confir med as having a role in autosomal dominant GEFS+ families.In addition,the phen otypes of the affected members may depend on the types and locations of these ge ne mutations.This review states the molecular genetic progress of GEFS+ in brie f.

Six hours after inhalation pulmonary injury,the pulmonary microvascular permeability (PMVP),pulmonary malondialdehyde (MDA) level,superoxide dismu-tase activity (SOD),the contents of protein and leucocytes in broncho-alveolar lavage fluid(BALF),and serum MDA level were determined in rats pretreated with allopurinol.In addition,the pathological changes of the lung tissues were also studied.It was found that early administration of allopurinol resulted in marked reduction of PMVP,and the protein content and leucocyte count in BALF.His-topathological examinations revealed that allopurinol could reduce the leucocyte accumulation in pulmonary vessels,interstitial leucocyte infiltration,interstitial and alveolar edema and hemorrhage,and vascular congestion.The serum and pulmonary levels of MDA also markedly decreased.The changes of pulmonary level of MDA were parallel to those of PMVP,and the protein content and leucocyte count in BALF in time course and in degree.The results listed here imply that the mechanism of the therapeutic effects of allopurinol on inhalation pulmonary injury is to reduce the production of superoxide anions through the inhibition of xanthine oxidase,in turn to inhibit the peroxidation of pulmonary lipids to alleviate pulmonary damage.

Epileptic encephalopathies are an epileptic condition characterized by epileptiform abnormalities associated with progressive cerebral dysfunction.These syndromes include early myoclonic encephalopathy and Ohtahara syndrome in the neonatal period,West syndrome and Dravet syndrome in infancy,myoclonic status in nonprogressive encephalopathies,and Lennox-Gastaut syndrome,Landau-Kleffner syndrome,and epilepsy with continuous spike waves during slow wave sleep in childhood and adolescences.Other epileptic syndromes such as migrating partial seizures in infancy and severe epilepsy with multiple independent spike foci may be reasonably added.In this paper,an overview of epileptic encephalopathies including clinical features,etiology,electroencephalogram characteristics,treatment and prognosis are provided.

Epilepsy is a common disorder of neurological system in children.Inborn errors of metabolism (IEMs) is one of an important etiology of epilepsy.Seizures may be the first and the major presenting feature of IEMs.IEMs are a relatively rare cause of epilepsy,but their recognition and diagnosis is very important because several disorders are treatable.This review will concentrate on diseases where epilepsy is the predominant clinical manifestation and especially where the disease course can be positively influenced by specific metabolic therapies.

Objective To clone human survivin gene and express survivin-an inhibitor of apoptosis proteins in Pichia pastoris eukaryotic expression system. Methods Full length survivin gene was amplified by PCR using survivin specific primers. The verified survivin gene by sequencing was subcloned into pPic9k. The recombinant plasmid was linearized by restriction enzyme cutting. The linear survivin gene was introduced into GS115/ His-cells by electroporation. The transformants were transferred onto YPD plates that contained different concentrations of G418 for screening the positive clones. The integrated survivin gene in positive clones was confirmed by PCR. Selected transformants were cultured in BMMY medium with 1 % methanol for inducing the expression of survivin protein. The expressed survivin protein was analyzed by ELISA. Results The cloned human survivin sequence was the same as that in the GeneBank. The recombinant pPic9k-survivin was constructed in Picha pastoris eukaryotic expression vector. After the linear digestion, the recombinant vector was introduced into GS115/ His-cells, the 6 positive clones against G418(4 mg/mL) were obtained and confirmed by PCR; the highest survivin protein was expressed when expressed for two days in 1 % methanol BMMY medium. Conclusions Improved survivin protein yield may be reached by modifying the experimental conditions. This will help to further study the biological functions of survivin and its roles in tumor developments.

The all-in-one femtosecond laser corneal refractive surgery,especially small incision lenticule extraction (SMILE),has gained more and more attention in clinic,because of its small incision,“no flap” and corneal biomechanical stability advantages.However,like any other kind of corneal refractive surgery,the all-in-one femtosecond laser refractive surgery not only exists its clinical advantages,but also has its limitations.It is very important to put into perspective clinical advantages and limitations of all-in-one femtosecond laser corneal refractive surgery.

Objective To explore the common factors' influence on serum gastrin level,and reveal the value of serum gastrin in the diagnosis of gastric precancerous lesions and gastric cancers.Methods Serum gastrin level of 3 906 serum samples was detected by ELISA.Results Serum gastrin level of patients over 60 years old was distinctively higher than that of other age groups.Serum gastrin level in antral diseases was higher than that in diseases of the body.HP positive group was higher than the negative one.The level progressingly increased from normal group to superficial gastritis and to gastric erosion or ulcer;and it decreased from gastric erosion or ulcer to atrophic gastritis,while it increased from atrophic gastritis to dysplasia,and it decreased from dysplasia to gastric cancer.Serum gastrin level was distinctively lower in gastric cancer than in other groups.Conclusion For people over 60 years old,their serum gastrin level has the tendence to increase.The location of gastric disease is an important factor affecting serum gastrin level.HP can increase the serum gastrin level.During gastric precancerous stage,the serum gastrin level may gradually increase with the diseases' progression,and decrease when gastric cancer is formed.Serum gastrin is a good marker to differentiate benign and malignant gastric diseases.

Clinical symptoms,multi screeming characters and pathological features of 15 cases of FNH were analysed retrospectively.11 cases were treated by operation.The results showed that three quarters(12/15) of the patients were male.Only one third(5/15) of the patients were diagnosed as FNH according to multi screeming of B US,CT and MRI.There were no complications for the 11 cases after operation.The results indicated it is difficult to diagnose FNH only by multi screeming methods.Operation is the best option for the treatment of FNH.
