Because absence of lymphoadenopathy, and often associated with haemophagocytic syndrome, the intravascular malignant lymphoma(IVL) is easy mistaken as malignant histiocytosis or connective tissue disease or vasculitis, the diagnosis was difficult while patients were alive. The clinical course of this disorder (IVL)was aggressive and carried a poor prognosis. The cases of this disorder are not too rare to be seen in our country. To enhance one′s ability to differentiate disorder in unknown fever diseases are extremely necessary.

A deficient of plasma VW factor-cleaving protease (ADAMTS13) and appearance of unusually large multimers induced platelets aggregation in capillaries and arterioles. It was critical pathogenesis of thrombotic thrombocytopenia purpura (TTP). ADAMTS13 activity has been measured over 1000patients of TTP and hemolysis uremia syndrome (HUS) since 1997. Diagnostic sensitivity and specificity,as well as clinical significance of ADAMTS13 deficiency for TTP patients were evaluated,and synthetical diagnosis basis of TTP were raised.

Infantile spasms is a type of refractory epilepsy syndrome.This epilepsy syndrome is characterized by special tonic spasms,a peculiar set of electroencephalographic findings termed hypsarrhythmia,and arrest of psychomotor development in most patients.The etiology is not clearly understood.Recently,mutations of the arista less related homeobox gene(ARX),cyclin-dependent kinase-like 5(CDKL5)/se-rine/threonine kinase 9 gene(STK9),membrane associated guanylate kinase 2 gene(MAGI2),et al,and abnormal chromosome had been found to be responsible for infantile spasms.In this review,progress of infantile spasms in molecular genetics are discussed.

Objective To summarize clinical experience of laparoscopic cholecystectomy (LC) for acute cholecystitis.Methods Two hundred and eighty patients with acute cholecystitis underwent LC in our hospita1.Results The LC was successfully completed in 268 cases,the other 12 patients were converted to open surgery because of massive adhesion at the Calot triangle (5 cases),severe hemorrhage (2 cases),Mirizzi syndrome (3 cases),Common bile duct injury (2 cases) were exectuted by bile duct repair and T tube drainage' and were Roux-en-Y chole-enterostomy).None of the patients had intra-abdominal hemorrhage,biliary leakage,or subphrenic abscess after the operation.Conclusions LC is safe and feasible in the treatment of acute cholecystitis,and successful surgery should be based on the skilled techniques and the knowledge of key points in the operation.Conversion to open surgery is necessary when LC is difficult.

OBJECTIVE: To establish a method of fingerprint position, sample transfer and fingerprint DNA extraction in contact samples. METHODS: Sixty-six cases were visualized by 502 glue fingerprint fumigation. Two methods, ordinary wipe and acetone wipe, were used to transfer cast-off cells of fingerprints from testing samples, respectively. DNA was extracted and purified by ultramicro magnetic bead kit. The data was resolved on genetic analysis after amplification. RESULTS: In 33 samples, 30 samples got better STR analysis by acetone wipe method. The peak range was 1,000-4,000 RFU and peak shapes were equable. It was hard to get ideal STR typing by ordinary wipe method. CONCLUSION The samples are visualized by 502 glue fingerprint fumigation and the case-off cells are transferred by acetone wipe method. The method shows better STR analysis result, which might be a better method for forensic science practice.

This paper reports a case of Ancylostoma duodenale parasitized in the hepatic flexure of colon and the case was misdiagnosed at the beginning. The causes of misdiagnosis are analyzed and the laboratory examination methods of hookworm are summarized.

Colorectal cancer is currently the third most common cancer worldwide,and there are still half of the patients undergoing recurrence and metastasis after surgical treatment,so it is necessary for colorectal cancer patients to receive radiation therapy routinely.Due to the side effects brought by radiotherapy,it is of great importance to solve how to minimize the radiation dose in radiation therapy and improve radiation sensitivity.In recent years,people discovered that microRNAs can not only be involved in the origins of colorectal cancer and progress,but also play a increasingly important role in cancer radiosensitivity.MicroRNAs can regulate tumor radiosensitivity by influencing tumor microenvironment and function on target genes.DNA damage response caused by radiation includes the activation of ATM,histone modification and chromatin remodeling,cell cycle arrest,damage repair and apoptosis.microRNAs can regulate tumor radiosensitivity through above processes.This review focuses on the mechanism of microRNAs in affecting DNA damage repair and prospects the future of microRNAs in influencing the sensitivity of cancer radiotherapy in clinical application.

Objective To explore the influence of age factor on the treatment of cutaneous hemangioma with (90Sr-90Y) applicator.Methods A total of 224 babies and children of different ages with cutaneous hemangioma were treated by using 90Sr-90 Y applicator.Then,the relation between their therapeutic effects and ages were analyzed respectively.Results The differences in the therapeutic effect between group of one month to less than one year and group of one to less than five years,and group of one month to less than one year and group of five to ten years,and between group of one to less than five ages and group of five to ten years (P＜0.05),were statistically significant.With an increase of the age,the recovery rate gradually decreased,but their effective rate,improvement rate and ineffective rate increased.In the 199 well-healed or effective patients,the differences in the distribution of treatment course between group of one month to less than one year and group of one to less than five years,and group of one month to less than one year and group of five to ten years,were statistically significant (P＜0.05); but the difference in the distribution of treatment course between group of one to less than five ages and group of five to ten years was not statistically significant (P＞0.05).The number of treatment course presented an increased tendency with an increase of the age for patients.Conclusions The age of patients is a factor influencing the therapeutic effect on cutaneous hemangioma with 90 Sr-90Y applicator.The younger the patients,the better their therapeutic effects,the shorter their courses of treatment,and the smaller the adverse reaction of beta ray.

The care and support for the patient of AIDS is a vital content,we should enhance international collaboration and intercourse of information,which can promote efficiency.This text shows an analysis on the actuality and characteristic of the support mode of the AIDS community in British.Its purpose is to summarize the successful experience for china and improve the support mode for AIDS.
