Objective: To observe the clinical efficacy of acupuncture plus navel acupuncture for patients with urinary retention after radical hysterectomy for cervical cancer. Methods: A total of 64 patients with urinary retention after radical hysterectomy for cervical cancer was divided into a navel acupuncture group (22 cases), an acupuncture group (18 cases) and an acupuncture plus navel acupuncture group (24 cases). All three groups received bladder function training and neuromuscular electrical stimulation. In addition, navel points were combined in the navel acupuncture group. Electroacupuncture was conducted to Qihai (CV 6), Zhongji (CV 3), Dahe (KI 12), Shuidao (ST 28), Ciliao (BL 32) and Huiyang (BL 35) in the acupuncture group. The acupuncture plus navel acupuncture group received both treatments. The catheter was removed after 3 d of treatment. Spontaneous urination, residual urine volume, urinary catheter dependence and recurrence after 3 d, 6 d and 9 d of treatment in each group were observed, respectively. Results: In the acupuncture plus navel acupuncture group, the markedly effective rates after 3 d, 6 d and 9 d of treatment were significantly higher than those in the navel acupuncture group and the acupuncture group; the urinary catheter dependence was lower than that of the other two groups, and the differences were statistically significant (P<0.05, P<0.01); the spontaneous urination time was shorter than that of the navel acupuncture group and the acupuncture group, and the differences were statistically significant (P<0.05, P<0.01); the residual urine volume was significantly less than that of the navel acupuncture group and the acupuncture group, and the differences were statistically significant (both P<0.01). After the catheter was removed, recurrence was observed from the next day after spontaneous urination was resumed. There were 2 cases of recurrence in the navel acupuncture group, 2 cases in the acupuncture group and 1 case in the acupuncture plus navel acupuncture group. The recurrence rate of the acupuncture plus navel acupuncture group was significantly lower than that of the navel acupuncture group and the acupuncture group (both P<0.01). Conclusion: Acupuncture plus navel acupuncture has satisfactory efficacy for urinary retention after radical hysterectomy for cervical cancer. It can significantly shorten the urinary retention time, reduce the patient's dependence on urinary catheter, and reduce the residual urine volume.

BACKGROUND: Animal experiments showed that recruitment maneuver (RM) and protective ventilation strategy of the lung could improve oxygenation and reduce extravascular lung water. This study was to investigate the effects of RM on respiratory mechanics and extravascular lung water index ( EVLWI) in patients with acute respiratory distress syndrome (ARDS). METHODS: Thirty patients with ARDS were randomized into a RM group and a non-RM group. In the RM group, after basic mechanical ventilation stabilized for 30 minutes, RM was performed and repeated once every 12 hours for 3 days. In the non-RM group, lung protective strategy was conducted without RM. Oxygenation index (PaO2/FiO2), peak inspiratory pressure (PIP), Plateau pressure (Pplat), static pulmonary compliance (Cst) and EVLWI of patients before treatment and at 12, 24, 48, 72 hours after the treatment were measured and compared between the groups. Hemodynamic changes were observed before and after RM. One-way ANOVA, Student's t test and Fisher's exact test were used to process the data. RESULTS: The levels of PaO2/FiO2 and Cst increased after treatment in the two groups, but they were higher in the RM group than in the non-RM group (P<0.05). The PIP and Pplat decreased after treatment in the two groups, but they were lower in the RM group than in the non-RM group (P<0.05). The EVLWI in the two groups showed downward trend after treatment (P<0.05), and the differences were signifcant at all time points (P<0.01); the EVLWI in the RM group was lower than that in the non-RM group at 12, 24, 48 and 72 hours (P<0.05 or P<0.01). Compared with pre-RM, hemodynamics changes during RM were significantly different (P<0.01); compared with pre-RM, the changes were not significantly different at 120 seconds after the end of RM (P>0.05). CONCLUSIONS: RM could reduce EVLWI, increase oxygenation and lung compliance. The effect of RM on hemodynamics was transient.

This study was purposed to investigate the expression and significance of glycosylphosphatidylinositol-specific phospholipase D (GPI-PLD) in bone marrow mononuclear cells (BMMNC) isolated from patients with acute myeloid leukemia (AML), GPI-PLD activity in BMMNC isolated from 78 patients with AML and 15 normal persons was measured by using GPI-anchored placental alkaline phosphatase (PLAP) as a substrate and Triton X-114 phase partitioning. The GPI-PLD mRNA expression was measured by semi-quantitive reverse transcription-polymerase chain reaction (RT-PCR). The results showed that the mRNA expression level and activity of GPI-PLD in BMMNC from de novo AML patients were 1.86 +/- 0.32 and 46.96 +/- 7.15% respectively; the mRNA expression level and activity of GPI-PLD in BMMNC from completely remission and refractory or relapsed patients were 1.26 +/- 0.29, 33.36 +/- 5.13%and 1.79 +/- 0.19, 44.31 +/- 7.22%, while those in BMMNC from normal controls were 1.27 +/- 0.23, 35.38 +/- 5.15% respectively. The mRNA expression level and activity of GPI-PLD in de novo and refractory or relapsed patients were obviously higher than those in normal controls with significant difference (p < 0.01), while the comparison between remitted patients and normal controls showed no statistical difference (p > 0.05). It is concluded that the expression level of GPI-PLD mRNA coincides with GPI-PLD activity. The mRNA expression and activity of GPI-PLD in de novo and refractory or relapsed patients are obviously higher than those in normal controls. It is worthy of further exploring whether GPI-PLD plays a certain role in process of leukemia pathogenesis.

OBJECTIVETo evaluate the ancillary diagnostic value of IgH gene rearrangements in those B-cell lymphoproliferative disorder cases whom are difficult in making a final diagnosis.

METHODSIgH gene clonal rearrangements were retrospectively analyzed in a total of 77 diagnostically difficult B-cell lympho-proliferative patients. Standardized BIOMED-2 system IgH gene clonality assay kit targeting FR1, FR2, FR3 was used, followed by heteroduplex-polyacrylamide gel electrophoresis (PAGE) and silver nitrate staining.

RESULTSThe final diagnoses of the 77 cases were: 12 cases of reactive lymphoid hyperplasia, 20 cases of atypical lymphoid hyperplasia or suspicious lymphoma, and 45 cases of B-cell lymphoma. Detection rates of at least one positive reaction were 2/12, 11/20 (55%), 36/45 (80%) in the three groups, respectively. In B-cell lymphomas, the clonality detection rate of FR1, FR2 and FR3 was 60% (27/45), 60% (27/45) and 56% (25/45), respectively. The type distribution were: 20 marginal zone lymphomas, including 18 extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue, 7 diffuse large B-cell lymphomas, 7 follicular lymphomas, 1 mantle-cell lymphoma, 1 Burkitt's lymphoma, 4 plasma cell neoplasms and 5 unclassified B-cell lymphomas. Rearrangements of FR1, FR2 or FR3 were not detected in 9 (20%) of the B cell lymphoma cases, nevertheless, one of them had developed liver lesion later, and was confirmed finally to be B cell lymphoma. Fourteen patients of reactive lymphoid hyperplasia with positive IgH gene clonal rearrangements, and atypical lymphoid hyperplasia had follow-up history available. Four of them were diagnosed as lymphoid malignancies upon further biopsy, and in three of them, clonal IgH gene rearrangements were detected.

CONCLUSIONSB-cell lymphoproliferative disorder requiring a detection of clonal IgH gene rearrangement for making a final diagnosis. Combined detections of three IgH FR1, FR2 and FR3 rearrangements provide important ancillary diagnostic value in confirming suspected B-cell lympho-proliferative disorders. It is important to take an additional biopsy or to follow-up those patients who that have a detectable IgH gene clonal rearrangement but without apparent morphological evidence of lymphoma. For cases with a negative IgH gene rearrangements, it might be necessary to perform clonality analysis for other forms of gene rearrangements including IgH or IgK and IgL in order to further improve the detection sensitivity.

OBJECTIVETo evaluate the outcome of precision-fit surface hemiarthroplasty in the treatment of femoral head osteonecrosis.

METHODSThe clinical data of 41 patients (48 hip joints) with femoral head osteonecrosis were reviewed. Of them, 30 were male and 11 were female, average age was 37 years old (ranging from 29 - 49). Thirty-five patients were at Ficat stage III and 13 at Ficat stage IV, their acetabula were relatively normal. The 41 patients (48 hip joints) underwent precision-fit surface hemiarthroplasties.

RESULTSThe mean duration of follow-up was 5.2 years. The average UCLA hip score at follow-up was improved significantly from 3.1 to 9.1 points for pain, 4.4 to 9.2 points for walking, and 5.5 to 7.1 points for activity (P = 0.001). The satisfaction rate was 88.6% for 35 at Ficat stage III, 69.2% for 13 at stage IV (P = 0.25). Eight hips failed; the UCLA hip score was not improved significantly; the postoperative X-ray examination showed that 7 femoral prostheses were implanted in a varus orientation (the angle between the femoral prosthesis stem and the anatomic axis of the femoral shaft was lower than angle of 130 degrees). Five-year survival rate was 83.0%.

CONCLUSIONSPrecision-fit surface hemiarthroplasty of the hip has the satisfactory result in treatment of the femoral head osteonecrosis on the basis of observing strictly operative indications and improving operative technique.

OBJECTIVETo research the effects of Qingyang Toujie Mixture (QTM) in combination with prednisone tablet on the balance of Th1 and Th2 (Th1/Th2) of systemic lupus erythematosus (SLE) patients of yin deficiency syndrome (YDS).

METHODSTotally 42 patients with SLE were recruited from clinics of internal medicine and hospitalization department of First Hospital Affiliated to Guangzhou University of Traditional Chinese Medicine from August 2009 to March 2011. They were randomly assigned to the treatment group (22 cases) and the control group (20 cases) according to the random digit table. Another 12 healthy subjects were recruited as the healthy control group from employees of First Hospital Affiliated to Guangzhou University of Traditional Chinese Medicine and healthy students in physical examinations. All patients took prednisone tablet. The dosage was adjusted according to the severity of SLE activity index and the condition: 40 -60 mg per day for severe active stage; 20-40 mg per day for moderate active stage; 15 -20 mg per day for light active stage; and less than 15 mg per day for those in the stable stage, respectively. When patients' condition had been stabilized for 1 to 2 weeks, the dosage was gradually reduced according to the method of hormone reduction. In case of the recurrence of symptoms or when complicated with lupus nephritis or lupus encephalitis uncontrollable, standard shock therapy with Cyclophosphamide Injection (0.5-1 g/m2 body surface area, intravenous dripping, once every 4 weeks) was performed. Patients in the treatment group took QTM additionally, one dose daily, taken in two portions, once in the morning and once in the evening. Those in the control group took placebos additionally, one dose daily, taken in two portions, once in the morning and once in the evening. The therapeutic course was 6 months for all. No measure was taken for those in the healthy control group. Venous blood was withdrawal before and after treatment. Th1 cytokines (IFN-gamma, IL-12) and Th2 cytokines (IL-10, IL-4) were detected by ELISA.

RESULTSCompared with the healthy control group, the serum Th1 cytokines such as IL-12 and IFN-gamma, Th2 cytokines such as IL-10 and IL-4 increased, the Th1/Th2 ratios such as IFN-gamma/IL-4 and IL-12/IL-10 decreased in the treatment group and the control group before treatment (P < 0.01). Compared with before treatment in the same group, the serum Th1 cytokines such as IL-12 and IFN-gamma decreased, the serum Th2 cytokines such as IL-10 and IL-4 decreased, the ratios of Th1/Th2 cytokines such as IFN-gamma/IL-4 and IL-12/IL-10 increased in the treatment group (all P < 0.05). Compared with the control group after treatment, IL-4 decreased, and the ratio of IFN-gamma/IL-4 increased in the treatment group (P < 0.05). Fewer patients suffered from adverse reactions in the treatment group than in the control group (P < 0.01).

CONCLUSIONQTM in combination with prednisone tablet was effective to improve the balance of Th1/Th2 cytokines, and alleviate the toxic and adverse reactions of hormone or immune inhibitors.
