Objective To analyse status of peripheral blood leukemic cells detected by flow cytometry in patients with acute leu‐kemia(AL) ,and to provide references for evaluating clinical efficacy and prognosis of AL .Methods The peripheral blood specimens of 87 cases of patients with AL ,including 53 cases of patients with acute myelocytic leukemia and 34 cases of patients with acute lymphoblastic leukemia ,were detected by using flow cytometry ,morphological changes in bone marrow cells were detected ,as well . Results The sensitivity ,specificity and positive predictive value in determination of acute myelocytic leukemia was 95 .6% ,34 .5%and 81 .3% respectively ,and those in acute lymphoblastic leukemia was 87 .3% ,45 .6% and 68 .9% respectively ,statistically signif‐icant differences were found in sensitivity ,specificity and positive predictive value (P<0 .05) .A total of 19 cases with negative mini‐mal residual disease had recurrence(26 .31% ) after 24 months ,and 68 cases with positive minimal residual disease had recurrence (86 .76% ) after 24 months ,and the recurrence rate between the two groups was statistically significant (P<0 .05) .Among all pa‐tients with positive minimal residual disease ,the recurrence rate in patients with high expression level of minimal residual disease (88 .23% ) was higher than that in patients with low expression level of minimal residual disease (47 .09% ) ,and the difference was statistically significant (P<0 .05) .Conclusion Flow cytometric analysis of peripheral blood leukemic cells may has significance for diagnosing relapse of AL and guiding clinical medication .
4.Study on application of B-type ultrasound guided modified Seldinger technique for PICC in patients with lung cancer
International Journal of Laboratory Medicine 2017;38(16):2188-2189,2192
Objective To investigate the clinical effect of adopting B-type ultrasound guided peripherally inserted central catheter (PICC) in the patients with lung cancer.Methods Two hundreds and ninety-five cases of lung cancer undergoing PICC in our hospital from January 2011 to May 2016 were selected as the research subjects and divided into the observation group (151 cases) and control group (144 cases) according to the PICC methods.PICC in the observation group adopted the B-type guided modified Seldinger technique,while the control group adopted the conventional method.The venous thrombus occurrence situation in the two groups was comparatively analyzed.Results (1) The platelet count (PLT),plasma D dimer (D-D) and thromboxane B2 (TXB2),endothelin (ET),6-keto-prostaglandin F1 alpha (6-keto-PGF1α) before PICC had no signigicant difference between the two groups (P>0.05).PLT,D-D,TXB2 and ET at 12,24 h after PICC in the observation group and control group were gradually increased,while plasma 6-keto-PGF1α was gradually decreased,the intra-group difference among different time points had statistical significant (P<0.05).PLT and plasma D-D,TXB2 and ET in the observation group were significantly lower than those in the control group,while keto-PGF1α was significantly higher than that in the control group,the difference between the two groups was statistically significant(P<0.05).(2)The incidence rate of venous thrombosis in the observation group was significantly lower than that in the control group,the difference was statistically significant between the two groups (P<0.05).Conclusion Adopting B-type ultrasound guided modified Seldinger technique for PICC in the patients with lung cancer has much lower incidence rate of venous thrombosis.
6.Reproduction of human endometriosis in nude mouse to test the effects of endostatin therapy
Medical Journal of Chinese People's Liberation Army 1982;0(03):-
Objective To reproduce the human endometriosis (EMS) in nude mouse, and to asssess the effects of endostatin in this model. Methods Endometrium tissue was collected from four women undergoing hysterectomy for EMS, and it was transplanted into 30 female BALB/c nude mice by subcutaneous injection (n=20) and intraperitoneal injection (n=10) respectively. The development of endometriotic lesions in nude mice was observed three times every week. Two weeks later, the successful rate in the two groups was estimated. The model mice in subcutaneous injection group were then randomized into treatment group (n=8) and control group (n=7). The mice in treatment group were injected with human endostatin (2mg?kg -1 ?d -1 ), while the mice in control group received an equivalent volume of PBS. All mice were sacrificed 14 days after treatment. Immunohistochemistry was used to determine the expression of vascular endothelial growth factor (VEGF). Results Transplantation was successful in 7 nude mice in abdominal implantation group and 15 nude mice in subcutaneous injection group. The success rate was 75% in subcutaneous injection group and 70% in abdominal implantation group, no significant difference was found between two groups. The level of VEGF in the nude mice treated with endostatin was significantly lower than that in the control group (P
7.Diagnosis and treatment of glenoid labrum injury of the shoulder with arthroscopy
Chinese Journal of Orthopaedics 2001;0(08):-
Objective To discuss the practical significance and clinical therapeutic effects of shoulder arthroscopy technique in the diagnosis and treatment of glenoid labrum injury. Methods In order to have an accurate diagnosis of glenoid labrum injury of the shoulder, X-ray, arthrography, MRI and arthrog-raphy and arthroscopy techniques were used respectively for thirty-six cases of glenoid labrum injury. Under shoulder arthroscopy, the injured glenoid labrum was partially resected in twenty-eight patients affected with single glenoid labrum injury. The injured glenoid labrum of five SLAP cases were treated with debridement under shoulder arthroscopy, and then the affected shoulder was immobilized by zero-degree traction. The injured glenoid labrum of three Bankart cases also underwent debridement under shoulder arthroscopy, and then treated with improved Bristow operation through limited incision. Results After 2-year follow-up, according to the standard criterion of U. S. Michasel Reese Medical Center, the total pain score and the total joint function score were 75 and 25 respectively; the patients' average score was 65 and 20 postoperatively, compared with 35 and 10 preoperatively. The clinical symptoms of all these cases were greatly improved and the unstable symptoms disappeared postoperatively in eight SLAP injury or Bankart injury patients and they all returned their preoperative activities. Conclusion Glenoid labrum is one of the most frequent parts of shoulder joint to be injured. Shoulder arthroscopy is a necessary and effective advanced technique for a definite diagnosis and treatment of glenoid labrum injury. There is some difficulty to carry out operation with arthroscopy and some specific instruments, however, it is necessary for the surgeon to understand and handle the technique.

Chinese Traditional and Herbal Drugs 1994;0(09):-
Objective To investigate the extraction technique for atractylenolide Ⅰ in Atractylodes macrocephala by supercritical CO_2 fluid extraction and develop a method used for determining the content of atractylenolide Ⅰ in the extract by HPLC. Methods The effects of seven facters, such as the extracting pressure, resolving pressure etc, to the extraction rate of atractylenolide Ⅰ in A. macrocephala by supercritical CO_2 extraction were investigated. RP-HPLC was used to determine the content of atractylenolide Ⅰ in extraction of A. macrocephala. The separation was performed on Hypersil ODS2 column with methanol-water (70∶30) as mobile phase. The flow rate was 1.0 mL/min and the wavelength of UV detector was 220 nm. Results The optimal extracting conditions: taking 10% alcohol as entraiter, the particle size of medicinal substances was 60 screen meshes, extracting pressure 25 MPa, resolving pressure 5 MPa, extracting temperature 40 ℃, resolving temperature 30 ℃, and the extracting time 4 h. Conclusion Supercritical extraction is time-shorter and efficient in extracting atractylenolide Ⅰ from A. macrocephala. It is suitable to both trial and industrialized production. The method established to determine the content of atractylenolide Ⅰ of A. macrocephala by supercritical extraction is simple, sensitive, and reliable.
