OBJECTIVETo explore the early rehabilitation effect of acupuncture on brain arousal in severe craniocerebral injury.

METHODSOne hundred and two cases of severe craniocerebral injury were randomly divided into an observation group and a control group, 51 cases in each one. Based on the conventional nursing care in neurological external medicine, in observation group, acupuncture was applied at Shuigou (GV 26), Neiguan (PC 6) and Sanyinjiao (SP 6) mainly. In control group, functional electric stimulation was applied at stimulate the affected muscles of the upper limbs. Thirty days later, the lucid rate from coma, lucid interval and clinical efficacy were compared between two groups. RESULTS; The lucid rate from coma was 82.4% (42/51) in observation group, which was higher than 56.9% (29/51) in control group (P < 0.01). The lucid interval in observation group was shortened remarkably as compared with control group (P < 0.01), and the clinical efficacy was superior apparently to that in control group (P < 0.01).

CONCLUSIONOn the basis of conventional treatment, acupuncture intervention at early stage can accelerate the recovery of brain arousal function in patients with severe craniocerebral injury.

OBJECTIVETo evaluate the effect and safety of BCG vaccine on initially treated pulmonary tuberculosis and its controlling effect on multidrug-resistant tuberculosis.

METHODSAll 360 volunteers with initially treated pulmonary tuberculosis of positive smear and culture were divided into immunotherapy group (180 cases, also BCG group) and control group (180 cases) at random pair. The patients in BCG group were treated with chemotherapy of a regimen of 2HRZ/2HR and immunotherapy with BCG for 4 months,and the first BCG vaccine was given a month after chemotherapy. Meanwhile, the patients in the control group were treated with chemotherapy of 2HRZ/4HR only.

RESULTS(1) The negative conversion rate of sputum smear in BCG group was 98.3% (177/180), and it was 97.2% (175/180) in control group. There was no significant difference between the two groups both at the ends of 4 and 6 months after treatment (chi2 = 0.1278, P > 0.05). (2) The positive conversion rate of sputum smear in BCG group was 2.3% (4/177), and it was 6.9% (12/175) in control group followed up for 5 years. The successful rate was 96.1% (173/180) in BCG group, and it was significantly higher than that of 90.6% (163/180) in control group (chi2 = 4.4643, P < 0.05). (3) In the 5-year follow up, bacteriologic result was similar to that of X-ray. (4) The occurrence rate of multidrug-resistant tuberculosis was 2.3% (4/177) in BCG group,significantly lower than that of 7.3% (13/178) in the control group (chi2 = 4.9513, P < 0.05).

CONCLUSIONAs an adjunct chemotherapy,immunotherapy with BCG vaccine should be helpful for patients with initially treated pulmonary tuberculosis. It would further strengthen the effects of chemotherapy and reduce the occurrence rate of multidrug-resistant tuberculosis.

OBJECTIVETo study the clinical characteristics of autoimmune hemolytic anemia (AIHA) with both warm and cold autoantibodies.

METHODSClinical and laboratory characteristics of 23 cases of AIHA with both warm and cold autoantibodies admitted to our hospital between January 1994 and April 2004 were analyzed retrospectively.

RESULTSIn comparison with the AIHA patients with both warm and cold autoantibodies in the 1980s, the present patients showed the following features: The proportion of this kind AIHA in all AIHA patients increased from 17.6% to 22.1%. There were more females, more primary cases (73.9%), more mixed subtypes of autoantibodies and more of IgM (56.5%). The hemolysis was related with thermal amplitude of autoantibodies and quantity of complement. The response to cortisone and other immunosuppressive drugs was good. The relapse rate was 77.8% in a median follow-up time of 4 months.

CONCLUSIONSAIHA with both warm and cold autoantibodies is related with the type and thermal amplitude of the autoantibody and the activation of complement. It can be treated effectively with combined immunosuppressive therapy, but the relapse rate is high.

A patient referred to our hospital, diagnosed with left idiopathic chronic orchialgia, was evaluated with a thorough medical and psychiatric history, physical examination, scrotal ultrasound and magnetic resonance imaging. Conservative management failed. The patient had temporary pain relief after undergoing outpatient cord block three times. Microsurgical denervation of the left spermatic cord was operated in March, 2011. A pain questionnaire was used to determine efficacy before and after operation, and complete pain relief was noted at one week after operation. The follow up period was 12 months, at the end of which the pain score was still zero. No complications, including testicular atrophy and hydrocele, occurred. Microsurgical denervation of the spermatic cord can be a minimally invasive, safe and effective management option for treatment of idiopathic chronic orchialgia.

OBJECTIVETo investigate the quantity, subset of dendritic cells (DC) and their costimulatory molecule expression in peripheral blood (PB) of the patients with myelodysplastic syndromes (MDS).

METHODSTotal DC (Lin1(+) HLA-DR(+)), myeloid DC (mDC) (Lin1(-) HLA-DR(+) CD11c(+)) and plasma DC (pDC) (Lin1(-) HLA-DR(+) CD123(+)) in fresh PB samples of 38 MDS patients and 19 normal controls were assayed by flow cytometry with the monoclonal antibodies. The expressions of costimulatory molecules CD80, CD86 and CD40 on these DCs were also assayed in the same way.

RESULTSThe number of total DC in PB of low-risk and high-risk MDS patients was significantly higher than that in normal controls [(33.7 +/- 7.0) x 10(6)/L, (56.3 +/- 29.0) x 10(6)/L vs (12.1 +/- 1.4) x 10(6)/L, respectively] (P < 0.05), that of mDC in PB of low-risk and high-risk MDS patients was higher than that of normal controls too [(16.7 +/- 6.3) x 10(6)/L, (28.7 +/- 17.6) x 10(6)/L vs (5.5 +/- 0.9) x 10(6)/L] (P < 0.05), but pDC in low-risk and high-risk MDS patients was not significantly higher than that in normal controls (P > 0.05). The percentage of total DC in PB mononuclear cells (PBMNC) of low-risk and high-risk MDS patients [(2.37 +/- 0.53)% and (3.58 +/- 1.39)% respectively and that of mDC (0.90 +/- 0.35)%, (1.51 +/- 0.70)% respectively] were higher than that of normal controls [(0.68 +/- 0.08)%, and (0.32 +/- 0.05)% respectively] (P < 0.05), but that of pDC in MDS cases was not higher than that of normal controls (P > 0.05). The expressions of CD80 and CD86 between MDS patients and normal controls had significant difference (P < 0.05).

CONCLUSIONSTotal DC and mDC were increased significantly in MDS, but pDC did not. The costimulatory molecules (CD80 and CD86) except CD40 expressed higher on the DC of MDS patients. It suggested that the inflammatory injury related APC increased in MDS, but the antitumour immunity related APC did not . What found here might be one of the mechanisms involved in the pathogenesis of MDS.

OBJECTIVETo investigate the quantities of monocyte-derived dendritic cell precursors (pDC1) and plasmacytoid dendritic cell precursors (pDC2) in peripheral blood mononuclear cells (PBMC) of severe aplastic anemia (SAA) patients before and after immune suppressive therapy (IST), the ratio of the pDC1 to pDC2, and the expression of co-stimulating molecules (CD80, CD86, CD40) on dendritic cells (DC) and B cells in SAA patients.

METHODSBy means of three color monoclonal antibody labeling technology, the quantities and ratio of pDC1 and pDC2 in PBMC were detected in 26 SAA patients at active phase, 13 at recovery phase and 15 normal controls respectively. The aforementioned parameters of 10 SAA patients were tested before and 2 months after IST. The expression of CD80, CD86 and CD40 on DC and B lymphocytes were detected in 16 SAA patients and 15 normal controls.

RESULTSThe percentages of pDC1 and the ratio of pDC1/pDC2 of controls were (0.41 +/- 0.05)% and 1.58 +/- 0.18 respectively, and those of SAA patients at active phase were (0.67 +/- 0.13)% and 2.70 +/- 0.32 respectively, [pDC1 (P < 0.05); pDC1/ pDC2 ratio (P < 0.01)]. The aforementioned parameters in convalescent SAA patients decreased to (0.43 +/- 0.10)%, and 1.78 +/- 0.36 respectively, being no difference from those of normal controls. The percentages of pDC1 and pDC2 in 10 SAA patients were (0.87 +/- 0.31)%, and (0.35 +/- 0.09)%, before IST, and (0.24 +/- 0.09)%, (0.14 +/- 0.04)%, after IST, being significantly decreased (P < 0.05). The percentages of CD86 expression on DC of controls was (11.97 +/- 4.31)%, and that of SAA patients was (29.84 +/- 3.02) % (P < 0.05). The percentages of CD80, CD40 and CD86 expression on lymphocytes of controls were (2.57 +/- 0.44)%, (7.34 +/- 1.22)% and (1.86 +/- 1.11)%, respectively, and those of SAA patients were (5.17 +/- 0.68)%, (8.85 +/- 2.94)% and (5.98 +/- 0.96)% respectively (P < 0.05, P < 0.01). The percentage of CD86 expression on B lymphocytes in controls was 8.04 +/- 0.66%, and in SAA patients was (20.46 +/- 2.78)%, (P < 0.05).

CONCLUSIONThe pDC subtypes were abnormal and the percentage of pDC1 is increased in SAA patients, which are associated with stage of this disease. DC and B Lymphocytes in SAA patients upregulated expression of costimulatory molecules (CD86) which cause the T lymphocyte abnormally activated.

OBJECTIVETo investigate the abnormal hematopoietic clone burden of the patients with myelodysplastic syndromes (MDS) and its clinical implication.

METHODSThe ratio of the metaphase with abnormal karyotypes to the total was regarded as the index of MDS clonal burden. Thirteen parameters were assayed and the correlations between these parameters and MDS clone burden were analysed.

RESULTSThe clonal burden of MDS patients was (67.4 +/- 36.2)%. It correlated positively with bone marrow blasts (r = 0.483, P < 0.05), negatively with hemoglobin level (r = -0.445, P < 0.05). The number of blasts, hemoglobin and erythrocytes in high clonal burden (>50%) and low clonal burden (< or = 50%) groups were significantly different (P < 0.05). CD4+ T lymphocytes of MDS patients and normal controls were (274.18 +/-71.85) x 10(6)/L and (454.82 +/- 205.88) x 10(6)/L (P < 0.05) respectively. CD8+ T lymphocytes between MDS patients and normal controls had no difference. The serum level of IL-2 of MDS patients and normal control groups were (6.29 +/- 3.58) g/L and (3.11 +/- 1.40) microg/L (P < 0.05) respectively; but no difference in the serum level of TNF between MDS and control groups. The ratio of CD4+ to CD8+ in high clonal burden patients was 1.90 + 0.52, and in low clonal burden patients was 0.97 +/- 0.44 (P < 0.05).

CONCLUSIONThe clonal burden and deficient T cell immunity are the indicators for predicting MDS patients clinical progression.

This study was aimed to evaluate expression levels of CD166, Fas and apoptosis-related proteins in bone marrow neutrophils of PNH patients and normal controls, and to analyze their correlation in order to explore whether exist apoptosis abnormality in BM neutrophils of PNH patients. The expression levels of CD16b, Fas and Bax, Bcl-2 in BM neutrophils of PNH patients and normal controls were assayed by flow cytometry; the difference of expression levels between patients and controls, and expression correlation between CD16b and apoptosis-related proteins were compared. The results showed that (1) the expression levels of CD16b on BM neutrophils of patients and controls were (20.36 +/- 9.05)% and (71.34 +/- 26.8)% respectively (P = 0.01); (2) the expression levels of CD95 on BM neutrophils of patients and controls were (62.83 +/- 32.11)% and (48.00 +/- 38.52)% respectively, there were no significant difference between CD95 expressions in BM neutrophils of PNH patients and controls and no significant correlation between expression of CD95 and CD16b on BM neutrophils of PNH patients (P > 0.05); (3) the expression levels of Bcl-2 in BM neutrophil cytoplasma of patients and controls were (8.64 +/- 5.40)% and (16.82 +/- 15.39)% respectively, there were no significant difference between Bcl-2 expression of patients and controls, and no significant correlation between the expression of Bcl-2 and CD16b in BM neutrophil cytoplasma of PNH patients (P > 0.05); (4) the expression levels of Bax in BM neutrophil cytoplasma of patients and control were (30.47 +/- 22.15)% and (48.47 +/- 15.99)% respectively, there were no significant difference between the Bax expressions of patients and controls, and no significant correlation between the Bax and CD16b expressions in BM neutrophil cytoplasma of PNH patients. In conclusion, BM neutrophils of PNH patients expressed apoptosis-related CD95, Bcl-2 and Bax without significant difference from the normal controls, and without significant correlation with the CD16b expression. It is suggested that the cell growth and decrease of PNH patients possibly are independent of abnormal apoptosis.
