1.Intravascular malignant lymphomatosis and Asian variant
Journal of Medical Postgraduates 2004;0(01):-
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.
2.Clinical significance of ADAMTS13 activity in thrombotic thrombocytopenic purpura patients
Journal of Medical Postgraduates 2003;0(03):-
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 1000patients 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.
3.Study Progress of Infantile Spasms in Molecular Genetics
Journal of Applied Clinical Pediatrics 1994;0(04):-
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.

Purpose:To investigate the relationship between cell apoptosis and dephosphorylated RB protein in human breast cancer. Methods:In our work,human breast cell lines (MCF-7/S,the chemosensitive cell line and MCF-7/ADR,the chemoresistent cell line)were evaluated. Chemosensitivity of two cell lines was evaluated by the MTT colorimetric assay;the expressive levels of dephosphorylated RB protein were detected with immunocytochemistry. Apoptosis rates were determined by flow cytometry(FCM). Results:ADR inhibited proliferation of chemosensitive cell line MCF-7/S ,the 50% inhibition concentration (IC 50 ) was 0.128 ?g/ml;And IC 50 of MCF-7/ADR was 10.89 ?g/ml. The chemotherapeutic sensitivity of MCF-7/S was more than that of MCF-7/ADR by 86 times . Before treatment with ADR,phosphorylated RB protein was positive in two cell lines,but dephosphorylated RB protein was negative;After treatment of different concentration ADR,when the concentration of ADR was increased,expression of dephosphorylated RB protein elevated accordingly in MCF-7/S,but no significant change in MCF-7/ADR. Apoptosis and cell cycle was detected by FCM assays shows ADR induced apoptosis of MCF-7/S more than MCF-7/ADR(P0.05).

Objective To explore the inhibiting effects of arsenic trioxide and cisplatin on MG-63 cells. Methods Using MTT assay,flowcytometry,phase contrast microscopy and electron microscopy methods,the therapeutic effect of arsenic trioxide was studied for the osteosarcoma in the cultured MG-63 cells in vitro,and compared these effects with cisplatin. The inhibitory rotes of cell growth and the effect of apoptosis and cell cycle were compared between arsenic trioxide and cisplatin on MG-63 cells. Results The contrast phase microscope revealed the adhesion ability of normal groups was good and cellular morphology showed epithelium cells. But the celhdar morphology showed irregular arrangement in arsenic trioxide groups and cytoplasmic vacuoles in cisplatin group. Electron microscope revealed the globular plasmalemma ecphymas in cell surface of control groups,the enlarged crista mitochondriales and the double-deck membrane structure appeared clearly. But electron microscope revealed globular plasmalemma processes in cell surface of arsenic trioxide groups,thinned crista mitochondriales and clearly seen karyopycnosis and nuclear membrane of apoptotic cells. The globular plasmalemma processes in cell surface of cisplatin groups were separated,nuclear membrane thickened and chromatin were in sandy shape. Both arsenic trioxide and cisplatin inhibited effectively MG-63 cells growth. There was a significant difference in different groups of inhibition ratios to the growth of cells(all P < 0.05). In 2,4,8,16,32,64,128 hours,the inhibition ratios(%) of arsenic trioxide(56.31±0.03,70.00±0.06,79.84±0.03,87.31±0.13,84.70±0.09,90.68±0.06,91.18±0.05) and cisplatin groups(7.55±0.15,15.70±0.17,30.72±0.07,49.80±0.05,45.11± 0.13,61.62±0.08,93.80±0.12) were obviously increased as compared with those in the control group(2.03± 0.07,2.78±0.08,3.11±0.01,5.67±0.04,12.23±0.04,18.65±0.04,24.45±0.04,all P < 0.05). Moreover the inhibition ratio of arsenic trioxide group in 2 to 32 hour was significantly higher than that of cisplatin group and the effect was more faster(all P < 0.05). Both arsenic trioxide and cisplatin could induce apoptosis MG-63 cells. There was a significant difference in different groups of the inhibition ratio to the growth of cells(F = 13.317,P < 0.05). The inhibition ratios(%) of arsenic trioxide on 24,36,48 hour(20.50±3.78,45.76±9.90,25.16±15.41),and cisplatin groups on 24,36,48 hour(12.55±1.51,18.85±3.40,12.37±5.43),were obviously increased as compared with those in the control group at the same time(6.57±1.48,8.03±2.08,6.54±1.30,P< 0.05 or<0.01). Both arsenic trioxide and cisplatin inhibited MG-63 cells cycle. There was a significant difference in different groups of the inhibition ratio to the growth of cells(F = 54.579,43.429,21.795,P < 0.05 or < 0.01). And the total inhibition ratios(%) in G1 cycle of arsenic trioxide(78.26±5.24) and cisplatin groups(80.48±2.81) were obviously increased as compared with those in the control group(57.49±6.65,all P < 0.05 or < 0.01). Conclusions Arsenic trioxide and cisplatin can effectively inhibit the proliferation of MG-63 cell line and induce the apoptosis of MG-63 cell line. And the effects induced by arsenic trioxide group were faster than that of cisplatin groups. Moreover arsenic trioxide can arrest the cell cycle of MG-63 cell line at G1 phase.
