Reticulocyte is the immature stage of red blood cell,which is an important indicator to reflect the hematopoietic function of bone marrow and to determine the efficacy of anemia and related diseases.In recent years, full-automatic blood cell analyzer provides reticulocyte count with advanced detection means, and more related parameters.In this paper,the correlation detection of reticulocyte parameters and its clinical application were summa-rized.

Hypoxic metabolism in solid tumor reduces chemoradiotherapy effect and become the obstacle in tumor therapy. Gene therapy is the most promising tumor treatment method, but currently using carriers cannot target tumors accurately. Anaerobic bacteria has become the transferring carrier in tumor gene therapy because it has tendency to hypoxia in solid tumors and can target solid tumors more accurately.

Ⅳ, change of phosphocreatine (PCr) content was very similar to thatof ATP. Content of ADP, AMP, Cr and HYPO was negatively correlated to ATP content. NAD content was also reduced. In summary, recently proposed hyperkalemic crystalloiddilluted blood protecting myocardium would not be sufficient enough and further improve-ment is quiet neccessary.

Objective To investigate the feasibility and safety of laparoscopic myomectomy in patients with large uterine myoma and the tumor located at special sites. Methods A retrospective study of 142 patients underwent laparoscopic myomectomy was done.In the patients,all the myomas were ≥10 cm in diameter;located at the cervix,uterus posterior wall near to the isthmic uteri,or broad ligament.The procedure was completed according to the volume and location of the tumors.For large myomas,the muscle layer was resected to remove the tumor,after removing the major part of the lesion(cut into pieces before moving out),the rest small parts were cut completely.Ligation was used for large tumors with sufficient blood supply in the surface or subserous myomas.For the myomas located in the broad ligament,the ligament was opened to pull out the tumor,and then the tumor was cut into pieces and resected at the root. Results The procedure was completed by laparoscopy in all of the patients,except in one who received laparoscopy-assisted resection.The removed tumors weighed 44 to 1903 g.The operation time ranged from 30 to 175 minutes.Intraoperative blood loss was 10 to 800 ml.No serious complications occurred.Among the cases,follow-up was available in 68 patients for 2 years.During the period,ultrasonography showed recurrent myoma in 2 patients. Conclusions With the improvement of the skills of laparoscopic myomectomy,indications for the laparoscopic operation can be widened.

Objective To observe the dynamic change of serum levels of perioperative procalcitonin (PCT ) ,C-reactive protein (CRP) ,interleukin 6(IL-6) and N-terminal brain natriuretic peptide(NT-proBNP) in the patients with lung cancer and to evaluate their value in postoperative monitoring .Methods Seventy-two patients with lung cancer were detected PCT ,CRP ,IL-6 and NT-proBNP levels before operation and on postoperative 1-5 d .The detection results were compared between the patients with cardiac injury and infection complications .Results Postoperative levels of serum PCT ,CRP ,IL-6 and NT-proBNP were increased in all the patients ;the peak value appearance of PCT ,CRP ,IL-6 and NT-proBNP in the patients with complications were earlier than that in the patients without complications ,moreover the peak value was significantly higher than that in the patients without complications (P<0 .05);the decrease speed of PCT ,CRP ,IL-6 and NT-proBNP in the patients with complications was slower than that in the patients without complications .Conclusion The combined detection of PCT ,CRP ,IL-6 and NT-proBNP may be become an effec-tive means to differentiate the postoperative complications .

Resistant starch is starch that escapes from digestion in small intestine and ferments in large intestine. Recent studies have demonstrated that resistant starch can decrease blood glucose, cholesterol, and triglyceride, enhance the sensitivity of insulin, and reduce body weight Therefore, it is useful for the prevention and treatment of diabetes. This article reviewed the effects of resistant starch on blood glucose, blood lipid and insulin resistance of diabetes.

Myocardial fibrosis is the common results of the development of a variety of heart diseases which leads to extracellular matrix protein metabolic disorders and causes cardiac remodeling owing to cardiac fibroblasts proliferation, eventually results in malignant arrhythmia, heart failure, and even the occurrence of sudden cardiac death. Effective inhibition of myocardial remodeling could prevent the occurrence of sudden death. To know the protein kinase C (PKC) effective mechanism of regulation on myocardial fibrosis, a new therapeutic target for reversing myocardial remodeling might be provided.

Objective To identify the clinical and neurophysiological features of multiple system atrophy (MSA) and explore diagnostic values using various techniques in electro neurophysiology Methods Forty four subjects diagnosed as multiple system atrophy (MSA) during 1983 to 2001 in PUMC Hospital were studied retrospectively about their clinical features, routine electromyography (EMG), nerve conductive velocity (NCV), somatosensory evoked potential (SEP), motor evoked potential (MEP), brainstem auditory evoked potential (BAEP) and visual evoked potential (VEP) The clinical features and the electroneurophysiologic results were analyzed in different subgroups (probable MSA and possible MSA, OPCA and non OPCA, classified MSA and unclassified MSA) Results Most patients were found to be suffered from autonomic failure (88 6%) and cerebella dysfunction (88 6%) The pyramidal sign was seen in 72 7% of patients No remarkable statistical differences were found in all of the above three domains The incidence of Parkinsonism was 36 4% of all the patients, which showed significant differences between probable and possible MSA (54 5% vs 18 2%), non OPCA and OPCA (50% vs 7 1%), unclassified MSA and classified MSA (52% vs 15 8%) EMG was abnormal in 7 patients (38 1%), all of them were neurogenic impairments The rates of abnormal EMG were varied differently between probable and possible MSA (54 5% vs 22 2%), non OPCA and OPCA (53 8% vs 14 3%), unclassified MSA and classified MSA (58 3% vs 12 5%), but without statistical differences The abnormal rates in BAEP,SEP, VEP and MEP were 56 7%, 28%, 23 1% and 20 0%, respectively, and there were no significant differences between subgroups Conclusions It should be hard to divide MSA into groups only by the clinical manifestations All EPs were abnormal in some extent The most sensitive test is BAEP in current study, but there were no differences among the subgroups in the rates of abnormal EPs The difference of EMG and NCV between the groups showed that the technique might be helpful in the diagnosis of MSA

Objective To investigate the genetic susceptibility to inflammatory bowel disease in China.Methods The pedigree of 5 probands with inflammatory bowel disease (2 with Crohn's disease and 3 with ulcerative colitis) were analyzed including familial history,clinical features,radiographic,endoscopic and pathological findings.A detailed family pedigree and information of the whereabouts of each relative were obtained.Results Crohn's disease was found in 2 families,each with two affected patients (two brothers or mother and a child).Ulcerative colitis was i'ound in 3 families,each with two or more affected patients (an elder sister and younger brother in the first family,mother and a child in the second family and grandparent and 2 grandchildren in the third family ).First-degree relatives were susceptibility to inflammatory bowel disease and siblings were affected more frequently.The member of the later generation was younger at diagnosis than the preceding generation. Offsprings had an earlier onset and more severe than affected parents. A high concordance for type and localization was found between males and females.Conclusions The patients with inflammatory bowel disease have genetic susceptibility and a few member may affect.It may result from multigene or autosomal recessive inheritance.

Objective:To assess human leucocyte antigen(HLA)-DRB1 allele polymorphism and analyze the association between DRB1 allele polymorphism and clinical classification of ulcerative colitis.Methods:60 patients were investigated for DRB1 gene by DNA microarray.The results were compared with those from healthy subjects.Results:The frequency of DR2 and DRB1*15 in UC patients were 45% and 41.7% respectively,which were significantly higher than those(23.3% and 21.7%)in controls,the odds ratio being 2.688 and 2.582 respectively(P
