OBJECTIVETo analyze the clinical efficacy of imatinib mesylate (IM) for Ph-positive or BCR-ABL positive chronic myeloid leukemia (CML) to couple the trough plasma concentrations (C mins) of IM with clinical responses and adverse events (AEs).
METHODSOne hundred and one CML patients received IM therapy, and Cmins of IM were determined in 30 patients.
RESULTS(1) Cumulative complete hematological response (CHR), major cytogenetic response (MCyR), complete cytogenetic response (CCyR) and negative BCR/ABL fusion gene rates were 96.6%, 86.5%, 77.5% and 47.2%, respectively, in CML-CP patients. In accelerated and blastic phases (AP and BC) patients, CHR, MCyR, CCyR and negative BCR-ABL fusion gene rates were 58.3%, 25.0%, 25.0%, 8.3%, respectively. (2) Mean Cmins of IM was significantly higher in the CCyR at 1 year [(1472 +/- 482) microg/L] group than in the non-CCyR at 1 years group [(1067 +/- 373) microg/L] (P < 0.05), and higher in the MMR at 1 year group than in the non-MMR at 1 years group [(1624 +/- 468) microg/L vs (1137 +/- 404) microg/L, P < 0.05].
CONCLUSIONIM significantly improves cytogenetic and molecular response, event-free survival, and overall survival for patients with Ph-positive CML. The Cmins of IM exerts a significant impact on clinical response (CCyR and MMR at 1 year).

Welder's siderosis was traditionally described as "benign pneumoconiosis" because of the absence of associated symptoms, functional impairment or pulmonary fibrosis. Although several authors have reported evidence of fibrosis in the lungs of welders, siderosis with local massive fibrosis has been rarely described. In this paper, we present a case of Welder's siderosis with local massive fibrosis mimicking lung cancer.

BACKGROUNDMuch research has been focused on ischemia/reperfusion injury (IRI) to the transplanted organs. As a free radical, nitric oxide (NO) plays an important role in IRI. In this study, the production of NO and its functions during IRI were monitored in rat models after allotransplantation of kidney grafts.
METHODSOf 75 male LEW rats, 30 served as donors, and the remaining 45 rats were divided into three groups (15 rats in each group): controls (group 1), kidney allotransplantation followed by bilateral nephrectomy during reperfusion (group 2), 2 hours before operation, donors and recipients were treated with N(G)-nitro L-arginine methyl ester (L-NAME), a NO synthase inhibitor, at a dose of 30 mg/kg (group 3). Bilateral nephrectomies were performed while kidney grafts were reperfused. The kidney grafts were hypothemically stored for 24 hours. The production of NO before and after reperfusion was measured by electron paramagnetic resonance (EPR). The creatinine level, the glomerular filtration rate (GFR) and the protein carbonyl content in tissue samples were recorded on the first and the fifth day after operation. The data were evaluated by one-way analysis of variance. Differences were considered to be statistically significant when a P value was less than 0.05.
RESULTSAfter reperfusion for 15 minutes, the production of NO increased remarkably and kept increasing till 120 minutes, after which the level returned to normal. In group 3, which was pretreated with L-NAME, creatinine levels were higher than those in group 2 at the 24th hour (4.10 +/- 0.50 mg/dl vs. 3.77 +/- 0.42 mg/dl, P < 0.05) and the 120th hour (3.19 +/- 0.79 mg/dl vs. 2.22 +/- 0.53 mg/dl, P < 0.05). GFR levels in group 3 were lower than those in group 2 at the 24th hour (0.50 +/- 0.12 ml/min vs. 0.71 +/- 0.19 ml/min, P < 0.05) and the 120th hour (0.59 +/- 0.38 ml/min vs. 1.27 +/- 0.23 ml/min, P < 0.01). The content of protein carbonyl in tissue samples of group 3 was lower than that in group 2 at the 24th hour (29.01 +/- 7.02 nmol/mg protein vs. 49.39 +/- 13.13 nmol/mg protein, P < 0.05), but was higher than that at the 120th hour (75.71 +/- 16.74 nmol/mg protein vs. 57.93 +/- 15.32 nmol/mg protein, P < 0.05).
CONCLUSIONSAfter transplantation of hypothemically stored kidney grafts, the increased NO production in the early stage has protective effects on the transplanted kidney. Application of L-NAME to inhibit NO production is harmful to the recovery of the renal functions of kidney grafts.

OBJECTIVESTo compare the efficacy of transurethral electrovaporization of prostate (TUVP) with transurethral resection of prostate (TURP).
METHODS206 patients with symptomatic benign prostatic hyperplasia (BPH) whose prostatic sizes were all less than 60 grams were randomly divided into two groups. 97 cases were treated by TUVP while the other 109 cases were treated by TURP. The patients who underwent either TUVP or TURP were followed up for 12-34 months with an average of 20 months postoperatively.
RESULTSBoth groups showed the significant decline in the mean IPSS (international prostatic symptom score) (P < 0.01), the mean PVR (Postovoiding Residual Volume) (P < 0.01), while increase in mean Qmax (Peak uroflow rate) (P < 0.01) in 12 months, 24 months after the operation. There were significant differences in the mean duration of operation or catheterization postoperatively (P < 0.05). The main complications of post-operation in the two groups were stress incontinence, TUR syndrome, urethral stricture, secondary bleeding.
CONCLUSIONSBoth TUVP and TURP are effective treatment for the patient with BPH whose prostatic size is less than 60 grams. TUVP spends shorter time of the operation and postoperative catheterization than that of TURP.

OBJECTIVE:
To retrospectively analyze the risk factors of avascular necrosis of femoral head (ANFH) after internal fixation in young and mid-aged adults.
METHODS:
From January 2007 to December 2017, femoral neck fracture patients (18-60 years old) treated by reduction and internal fixation were retrospectively studied in Peking University Third Hospital. We recorded their gender, age, body mass index (BMI), American Society of Anesthesiology (ASA) grade, reason of injury, fracture side, interval between injury and surgery, location of fracture line, Garden classification, Pauwels classification, reduction method (open or closed), internal fixation and reduction quality. The diagnosis of ANFH was confirmed based on X-ray and MRI images during the follow-up. The internal fixation method included cannulated compression screw (CCS) or dynamic hip screw (DHS, with or without anti-rotation screw). χ2 test and Logistic regression analysis were used to analyze the relationship between the various factors and postoperative ANFH.
RESULTS:
A total of 113 patients were included in this study, including 63 males and 50 females with an average age of (43.17 ± 12.34) years. They were followed up by (25.08 ± 16.17) months. ASA grade included grade I (21 cases), grade II (55 cases) and grade III (37 cases). The reasons of injury included low-energy trauma (76 cases) and high-energy (37 cases). The fracture line included subcapital type (37 cases), transverse type (74 cases) and basal type (2 cases). Garden classification included type I (3 cases), type II (46 cases), type III (39 cases) and type IV (25 cases). Pauwels classification included type I (21 cases), type II (55 cases) and type III (37 cases). Interval between injury and surgery was (3.88 ± 3.66) days, 108 patients and 5 patients performed closed and open reduction respectively. 63 patients performed CCS, and 50 patients performed DHS. The reduction quality included grade A (91 cases), grade B (18 cases) and grade C (4 cases). 18 patients developed ANFH after surgery, the incidence rate was 15.93% (18/113). The result of χ2 test showed the reason of injury (OR=0.19, P < 0.01), Garden classification (OR=0.13, P < 0.01), Pauwels classification (OR=0.12, P = 0.02), internal fixation method (OR=3.29, P = 0.04) and reduction quality (OR=0.33, P < 0.01) were significantly associated with ANFH. These five factors were further included into the Logistic regression analysis, and its results showed that the reason of injury (OR=4.11, P = 0.03) and Garden classification (OR=4.85, P = 0.04) were statistically significant.
CONCLUSION
The reason of injury, Garden classification, Pauwels classification, internal fixation and reduction quality may increase the risk of ANFH after surgery, and the reason of injury and Garden classification were much more significant.

The decline of body function and senile diseases caused by aging seriously affect human health and life span, which is an important topic in the field of life science. Bazi Bushen capsules is a representative Chinese patent medicine for tonifying essence, invigorating Qi and anti-aging, guided by Qiluo doctrine, and essence, Qi and spirit theory. Previous pharmacological and clinical studies have confirmed that this preparation has the comprehensive advantages of anti-aging, and prevention and treatment of aging-related diseases. Among them, pharmacological studies showed that Bazi Bushen capsules had the effect of improving the appearance status of mice, improving the level of sex hormones, inhibiting the formation of atherosclerosis, improving cardiac function, improving learning and memory cognitive ability, improving neurological function, improving osteoporosis and muscle function, improving sperm count and quality. The mechanism was related to the up-regulation of the recombinant sirtuin (SIRT6) level, down-regulation of the levels of aging-related proteins p53 and p16, up-regulation of telomerase reverse transcriptase level, and alleviation of inflammation and oxidative response. Clinical studies have proved that it can improve the symptoms of patients with kidney essence deficiency, improve exercise ability, and improve the sexual function of impotence patients. Anti-aging research of Bazi Bushen capsules based on Qiluo doctrine fully embodies the new mode of academic innovation and transformation of traditional Chinese medicine (TCM) with the combination of "theory-new drug-experiment-clinic", which has made a demonstration for the anti-aging research of TCM.
