Objective To observe the changes of respiratory musc]e strength by traditional Chinese medicine combined with cholinesterase inhibitors in myasthenia gravis (MG) patients.Methods Thirty-four cholinesterase inhibitor-resistant patients,of them 14 were MG patients with stage Ⅰ ,and 20 were stage Ⅱ ,were treated with bromide dimethylcarbamate ( 360-480 mg/d ).Traditional Chinese potion were administered in those without effectiveness,and the dosages of bromide dimethylcarbamate decreased with Traditional Chinese potion lasting for 4-6 months.Vital capacity ( VC ),maximal voluntary ventilation ( MVV ),maximal inspiratory pressure ( PIM ),maximal expiratory pressure ( PEM ),respiratory centre driving pressure ( P0.1 ),residual volume ( RV )were measured before and after treatment.Results The amelioration of VC,MVV,PIM,PEM,P0.1 ,RV,respiratory muscle strength and other indicators of 34 MG patients were not obviously after treatment with cholinesterase inhibitor alone ( P ＞ 0.05 ).After treatment with traditional Chinese medicine combined with cholinesterase inhibitors,VC,MVV,PIM,PEM ( before treatment:76.66% ± 18.59%,68.03 % ± 10.45 %,43.25 % ± 18.16%,21.75 % ±14.44% ) increased significantly in all 34 MG patients( after treatment:86.91% ± 14.87% ,75.11% ± 11.17%,52.66% ±20.32% ,28.56% ± 10.06% ) ( P ＜ 0.05).RV decreased from 164.94% ± 67.97% to 143.16% ±79.21% (P ＜0.01 ),and respiratory muscle strength,endurance and other indicators significantly improved (P ＜0.01).PIM(65.80% ±28.03% to 52.66% ±20.32%),and PEM (37.03% ±20.57% to 28.56% ±10.06%)improved more significantly in group stage than in group stage (P ＜0.01 ).Respiratory muscle endurance in stage Ⅰpatients ( 108.71% ± 17.56% ) improved significantly than stage Ⅱ patients (96.01% ± 14.12% ,P ＜ 0.01 ).Conclusions Traditional Chinese medicine combined with cholinesterase inhibitors could effectively improve the lung function and respiratory muscle strength in patients with resistance of the cholinesterase inhibitors.The improvement of lung function,respiratory muscle strength were more obviously in stage Ⅰ patients than in stage Ⅱ patients.Respiratory muscle strength and endurance were improved greater in stage Ⅱ than in stage Ⅰ patients.

OBJECTIVETo compare the clinical effects of circumcision and the foreskin-deglove plus shaft-fix (FDSF) procedure in the treatment of phimosis or redundant prepuce in obese adult males (body mass index [BMI] ≥ 28 kg/m²).

METHODSForty-four obese adult men with phimosis or redundant prepuce underwent circumcision (n = 24) or FDSF (n = 20) according to their own wishes. The patients in the circumcision and FDSF groups were aged (26.38 ± 4.24) and (26.90 ± 3.14) years, with BMIs of (27.77 ± 0.77) and (28.07 ± 2.28) kg/m² and penis lengths of (3.51 ± 0.46) and (3.50 ± 0.59) cm, respectively. The operations were performed under local anesthesia with lidocaine plus ropivacaine mesylate.

RESULTSThe operation time of circumcision was (28.04 ± 2.65) min and that of FDSF was (45.45 ± 3.49) min. At 6 months after surgery, normal penile erection was found in all the patients, the penis length was significantly longer in the FDSF than in the circumcision group ([5.01 ± 0.73] vs [3.70 ± 0.47] cm) , and the rate of satisfaction with penile appearance was markedly higher in the former than in the latter group (3.25 ± 0.71 vs 2.83 ± 0.56).

CONCLUSIONThe foreskin-deglove plus shaft-fix procedure under local anesthesia with lidocaine and ropivacaine mesylate may achieve desirable penile erection and appearance in the treatment of phimosis or redundant prepuce in obese adult patients.

In this paper, the process performance indexes (PPIs) P(p) and P(pk) were introduced and applied to evaluate the process capability and quality consistence of Chinese medicine products. The historical quality analysis data of Qingkailing injection were collected and taken as the research object. The confidence intervals of P(p) and P(pk) were estimated based on the Bootstrap sampling methods. Results showed that the value and width of the confidence interval P(p) of were smaller that of P(pk) suggesting that the P(pk) index was more sensitive than P(p) in process capability analysis. Within the production period concerned, the P(pk) values estimated from different quality indexes of Qingkailing injection, such as baicalin, cholic acid, geniposide and total nitrogen, were 1.122, 2.055, 1.564 and 0.891, respectively. It could be found that the cholic acid had the highest process capability, followed by the geniposide and baicalin. The total nitrogen had the lowest process capability, indicating that it is necessary to reinforce the quality management of total nitrogen related manufacturing processes. The case studies demonstrate the effectiveness and feasibility of PPIs, which are convenient to be used in production practice of Chinese medicine.

A total of 1 100 patients underwent renal transplantation in the Organ Transplantation Center,Second Affiliated Department of General Hospital of Chinese PLA between 1988 and 2008 were collected,and retrospective analysis was performed in five female patients with malignant tumor,which appeared at 68 months (20-132 months) following renal transplantation,including 2 with renipelvic and uretal cancer and 3 with bladder cancer. Two of the 3 patients with bladder cancer presented homolateral renipelvic and uretal metastasis. Three cases and 1 case of upper uretal cacer were observed at the homolateral or heterolateral of kidney grafts respectively. The main characteristic of sign was iterative and painless gross hematuria. The 5 patients underwent renal transplantation with intravesical instillation therapy and nephrectomy. All patients were survived without rejection in the 1-62 months follow-up. The incidence of malignancy in renal allograft recipients is much higher than that in normal ones,which is related to the long term use of immunosuppressants. Urinary epithelial cancer is the main complicating carcinoma and the first choice of treatment is surgical operation. Based on the normal renal grafts function,the dose of immunosuppressants should be as low as possible,Moreover,radiotherapy or chemiotherapy should be adopted according to the types and stages of tumor complicating renal transplantation.

Objective To study the relationship between the MDR1 gene expressions and CD56 antigen expression in patients with de novo acute myeloid leukemia(AML) and to explore the role of this two factors in clinical drug resistance and their correlation. Methods A real-time quantitative RT-PCR method was established for detecting MDR1 expression levels and three-color flow cytometry analysis using CD34/ SSC gating was used to examined CD56 antigen expression in 79 de novo AML patients. Results CD56 an-tigen was recorded in 19 out of 79 cases (24.1%) and particularly in those with M5 cytotypes. Moreover, CD56 expression was significantly associated with unfavorable cytogenetic abnormalities (P<0.05), Patients with t(8:21)had a significantly higher incidence (57.1%, 4/7) of CD56 expression than those with favora-ble karyotype(P<0.05). CD56~+ AML patients had a higher incidence of splenohepatomegalia and lactate dehydrogenase level than CD56~- patients(P<0.05). The median expression levels of MDR1 was statistical-ly higher in CD56~+ AML patients than that in CD56 patients(P<0.001). Patients with both high levels of MDR1 and CD56~+ had a significantly lower CR(complete remission) rate than those with both low MDR1 level and CD56 (58.8% vs 89.2%, P<0.01). Conclusion There is a linear correlation between MDR1 gene expression and CD56 expression in AML. Quantification of the MDR1 gene expression together with CD56 antigen expression is more effective to the judgement of prognosis in AML.

Objective To analyze the incidence and risk factors for regional nodal failure(RNF) and chest wall recurrence(CWR) in T1 or T2 breast cancer patients(median age 44 year-range 26-72) with 1-3 positive axillary nodes treated with postmastectomy radiotherapy limited to the regional nodes.Methods From 1990 to 1999,320 patients were treated with postmastectomy(radical or modified radical) radiother- apy confined to the supraclavicular and internal mammary nodes with a median dose of 50 Gy in 25 fractions over 5 weeks.The median number of nodes examined was 8 (range 1-24).The median lymph nods rate (LNR) was 25% (range 5%-100%).Results The 5-year overall survival rate and disease free survival rate was 89.7% and 83.4%,respectively.The 5-year RNF and CWR was 7.9% and 5.7%,respectively. The 5-year RNF in patients with LNR＜30% and≥30% was 4.4% and 14.0% (P=0.002).The 5-year CWR in the subgroups with LNR＜30% and≥30% was 3.5% and 9.6% (P=0.018).In age≤35 year eld patients with LNR≥30%,the 5-year RNF and CWR was 40.0% and 20.0%.In T2 patients with LNR≥30%,the 5-year RNF and CWR was 15.8% and 12.2%.Age and LNR were independent prognostic factors for RNF+CWR,LNR was the only independent prognostic factor for CWR by multivariate analysis. Conclusions In T1 or T2 breast cancer patients with 1-3 positive axiliary nodes treated with radical or modified radical mastectomy,a relatively high incidence of chest wall recurrence is observed in the subgroup of patients with lymph nods rate of 30% or greater accompanied by a T2 primary tumor or age≤35 years old. Lymph nodes rate is the only significant prognostic factor of chest wall recurrence.For these patients,post- operative lymphatic drainage area and chest wall irradiation should be considered.

Objective To explore the relation between the changes of respiratory muscle strength and both the changes of pulmonary function and the severity of myasthenia in patients with myasthenia gravis (MG). Methods We measured the respiratory muscle strength (maximal inspiratory pressure [PIM], maximal expiratory pressure [PEM] and P0.1) and pulmonary function (vital capacity [VC],maximal voluntary ventilation [MVV], peak flow [PF], R5 and R20) of 50 patients with type Ⅱ MG (group B), 16 patients with type Ⅰ MG (group A) and 30 healthy controls (group C). In addition, we analyzed the correlation between the pulmonary function and both the changes of respiratory muscle strength and the severity of myasthenia in group B. Results Comparison with group C, patients in group A had significantly decreased level of MW and P PIM, and statistically increased level of R20 and R5 (P<0.05);additionally, the level of VC, MW, PF, PIM and PEM, in group B decreased markedly with R20 increased markedly only as compared with that in the controls (P<0.05). Patients in group B showed significantly decreased level of PIm and PEM, and increased level of R20 and R5 as compared with the patients in group A (P<0.05). The level of PIM< PEM. MW and VC in group B was positively correlated to the absolute scores of severity of myasthenia in patients with type II MG (r=0.550, P=0.002; r=0.653, P=0.000; r=0.511,P=0.000; r=0.353, P=0.010). The level of PIM had positive correlation with the level of MW, VCand PF, so was the level of PEM. Positive correlation was also found between the level of PIM and PEM.Conclusions PatientswithtypeIMGinthe early stagemaynotmanifested ashavingmyasthenia,buthad weak strength and tolerance of respiratory muscle, thus, the level of MW, PIM,R10 and R5 might be the sensitive indexes in its early diagnosis. Changes of pulmonary function and respiratory muscle strength in patients with type Ⅱ MG were more obvious as compared with those in patients with type Ⅱ MG and these changes were positively correlated to the absolute scores of severity of myasthenia, which were consistent with the respiratory muscle strength and ventilatory function defects.

OBJECTIVETo explore the causes and mechanisms of children elbow joint injury led to elbow varus.

METHODSOne hundred children with elbow varus causded by elbow joint injuries were retrospectively studied during January 2005 to April 2008 in department of child orthopedics involving 54 males and 46 females with an average age of 9.7 years old ranging from 7 to 16 years. The anterior-posterior and lateral position X-ray films of elbow joint continuous 12 to 18 months (means 15 months) of all the cases were collected. The postoperative X-ray films were observed to analyze the cause of elbow varus.

RESULTSThere were 81 cases caused by epiphyseal dysplasia, growth imbalance, included 47 cases of humeral supracondylar fractures, 16 cases of entire epiphysis separation of distal humerus, 11 cases of humeral lateral condyle fractures, 7 cases of humeral medial condyle fractures. There were 19 cases caused by ulna drift and rotation of the distal fracture end,the ulnaris cortibal bone crushing and collapse involving 11 of humeral supracondylar fractures, 2 of entire epiphysis separation of distal humerus, 5 of humeral lateral condyle fractures, 1 of humeral medial condyle fractures.

CONCLUSIONThere are two main factors of formation for the children elbow varus deformity: the main causes is epiphysial dysplasia after fracture and imbalance growth of epiphysis; the secondary reasons is ulnar inclination of the distal fracture, rotation of the distal fracture, fracture shift such as ulnar bone cortical extrusion collapse.

Objective To investigate whether the gene polymorphisms of cytochrome P450(CYP) 2E1 are associated with the risk of anti-tuberculosis drug induced hepatotoxity (ADIH).Methods In this case control study, 339 patients who matched the diagnosis criteria of tuberculosis were included. The gcneral healthy status and liver biochemical parameters were checked in all these patients. Polymerase chain reaction-restriction fragment length polymorphism (PCR RFLP) technique was used to determine CYP 2Et polymorphisms. The statistic analysis were performed by using both univariate and multivariate Logistic regression analysis. Results The allele frequencies of CYP 2E1 7632T/A, 1019C/T and 1259G/C in 103 tuberculosis patients of ADIH group were 17.5%, 26.2%and 27.2 % respectively, while those in 236 tuberculosis patients of control group were 29.7 % ,39.4 %and 40.7%, respectively (x2 =5.539, P＜0.05; x2 =5.458, P＜0.05; x2 =5.628, P＜0.05). The results of univariate analysis demonstrated that the risk of concurrent ADIH was significantly higher in patients with wild genotypes of CYP 2E1-7632T/A, CYP 2E1-1259G/C, CYP 2E1-1019C/T than in patients with other genotypes. After adjusted for sex, occupation and alcohol consumption status, the results of multivariate Logistic regression analysis also showed that wild genotypes of CYP 2E1-7632T/A, CYP 2El-1259G/C, CYP 2E1-1019C/T were significantly associated with higher risk of ADIH. The results of interaction analysis indicated that the wild genotypes of CYP 2E1-7632T/A and CYP 2E1-1259G/C or CYP 2E1-1019C/T had synergetic effects on the development of ADIH.Conclusions The risk of concurrent ADIH is significantly higher in patients with wild genotypes of CYP 2E1-7632T/A, CYP 2E1-1259G/C, CYP 2E1-1019C/T compared to patients with othergenotypes. Wild genotypes of CYP 2E1-7632T/A and CYP 2E1-1259G/C or CYP 2El-1019C/T have synergetic effects on the development of ADIH.
