As there is widely application in clinical diagnosis and treatment with complete blood count(CBC)and differential count(DC),the experts of clinical hematology laboratory in the word have paid highly attention to the review of CBC and DC.In this paper,we would like to have an introduction for the suggested criteria for action following automated CBC and WBC differential analysis obtained from The International Consensus Group for Hematology Review and Clinical and Laboratory Standards Institute (CLSI).

Icaritin, a prenylflavonoid derivative from Epimedium Genus, has been shown to exhibit many pharmacological and biological activities. However, the function and the underlying mechanisms of icaritin in human non-small cell lung cancer have not been fully elucidated. The purpose of this study was to investigate the anticancer effects of icaritin on A549 cells and explore the underlying molecular mechanism. The cell viability after icaritin treatment was tested by MTT assay. The cell cycle distribution, apoptosis and reactive oxygen species (ROS) levels were analyzed by flow cytometry. The mRNA and protein expression levels of the genes involved in proliferation and apoptosis were respectively detected by RT-PCR and Western blotting. The results demonstrated that icaritin induced cell cycle arrest at S phase, and down-regulated the expression levels of S regulatory proteins such as Cyclin A and CDK2. Icaritin also induced cell apoptosis characterized by positive Hoechst 33258 staining, accumulation of the Annexin V-positive cells, increased ROS level and alteration in Bcl-2 family proteins expression. Moreover, icaritin induced sustained phosphorylation of ERK and p38 MAPK. These findings suggested that icaritin might be a new potent inhibitor by inducing S phase arrest and apoptosis in human lung carcinoma A549 cells.

Primary pigmented nodular adrenal disease (PPNAD) is a kind of autosomal dominant inherited disease. Patient in the study presented with Cushing's syndrome, and clinical and pathological diagnosis of PPNAD was confirmed. It is now confirmed that there are two relevant genes and their mutations may lead to PPNAD. This study showed no mutations in the patient, surpecting if there would be an alternative mechanism or a new gene in playing the role.

Severe tracheal stenosis can not only cause critical medical problems such as severe shortness of breath, hypoxia, and even orthopnea, but also impose overwhelming challenges on the physicians, particularly the anesthesiologist. Life-threatening airway obstruction can make the patient's gas exchange extremely difficult.Though several options could be offered regarding the treatment of tracheal stenosis, normally, tracheal resection and following reconstruction is the first choice for severe airway stenosis. Successful surgical intervention relies on the close communication and cooperation between surgeons and anesthesiologists. In these cases, airway management is the top issue for the anesthesiologist, and the level of difficulty varies with stenosis location, severity of stenosis, and surgical technique. Extracorporeal membrane oxygenation (ECMO), or cardiopulmonary bypass (CPB), is rarely utilized for the surgery, but for those impossible airways due to nearly complete tracheal obstruction, ECMO or CPB could be the final choice for anesthesiologists. Here we report a case of successful urgent airway management for tracheal resection and reconstruction assisted by temporary CPB.

OBJECTIVETo compare the effect of transurethral resection of the prostate combined with endocrine therapy (TURP + ET) with that of αlA-blockers combined with ET ((αlA-b + ET) in the treatment of bladder outlet obstruction (BOO) in patients with advanced prostate cancer (PCa), and to investigate the safety of the TURP + ET for the treatment of PCa with BOO.

METHODSWe retrospectively analyzed 63 cases of PCa with BOO, 28 treated by αlA-b + ET and the other 35 by TURP + ET. We obtained the residual urine volume (RV), maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and quality of life score (QoL) before and after treatment along with the overall survival rate of the patients, followed by comparison of the parameters between the two methods.

RESULTSAt 3 months after treatment, RV, IPSS, and QoL in the TURP + ET group were significantly decreased from (137.8 ± 27.6) ml, (22.3 ± 3.6), and (4.2 ± 0.8) to (29 ± 13.6) ml, (7.8 ± 2.1), and (1.6 ± 0.5) respectively (P < 0.05), while Qmax increased from (5.6 ± 2.1) ml/s to (17.6 ± 2.7) ml/s (P < 0.05); the former three parameters in the αlA-b + ET group decreased from (133.6 ± 24.9) ml, (21.5 ± 3.2), and (4.7 ± 1.1) to (42 ± 18.3) ml, (12.8 ± 2.6), and (2.5 ± 0.7) respectively (P < 0.05), while the latter one increased from (6.3 ± 2.4) ml/s to (11.7 ± 2.3) ml/s (P < 0.05), all with statistically significant differences between the two groups (P < 0.05). The overall survival rate of the TURP + ET group was not significantly different from that of the αlA-b + ET group (51.4% vs 46.4% , P > 0.05).

CONCLUSIONTURP + ET is preferable to αlA-b + ET for its advantage of relieving BOO symptoms in advanced PCa without affecting the overall survival rate of the patients.

PURPOSE: To report the 5-year follow-up results of a randomized controlled trial comparing bipolar transurethral resection of the prostate (TURP) with standard monopolar TURP for the treatment of benign prostatic obstruction (BPO). MATERIALS AND METHODS: A total of 220 patients were randomized to bipolar plasmakinetic TURP (PK-TURP) or monopolar TURP (M-TURP). Catheterization time was the primary endpoint of this study. Secondary outcomes included operation time, hospital stay, as well as decline in postoperative serum sodium and hemoglobin levels. All patients were assessed preoperatively and followed-up at 1, 6, 12, 24, 36, 48, and 60 months postoperatively. Parameters assessed included quality of life, transrectal ultrasound, serum prostate-specific antigen level, postvoid residual urine volume, maximum urinary flow rates (Qmax), and International Prostate Symptom Score. Patient baseline characteristics, perioperative data including complications, and postoperative outcomes were compared. Complication occurrence was graded according to the modified Clavien classification system. RESULTS: PK-TURP was significantly superior to M-TURP in terms of operation time, intraoperative irrigation volume, resected tissue weight, decreases in hemoglobin and sodium, postoperative irrigation volume and time, catheterization time, and hospital stay. At 5 years postoperatively, efficacy was comparable between arms. No differences were detected in safety outcomes except that the clot retention rate was significantly greater after M-TURP. CONCLUSION: Our results indicate that PK-TURP is equally as effective in the treatment of BPO, but has a more favorable safety profile in comparison to M-TURP. The clinical efficacy of PK-TURP is long-lasting and comparable with M-TURP.

Objective To explore whether autoreactive antibody presents in patients with sporadic idiopathic hypoparathyroidism(sIHP).Methods The subjects including 26 patients with sIHP and 112 genealogical members as well as 60 age-and sex-matched healthy controls.Anti-parathyroid antibodies in the sera were assayed by indirect immunofluorescence.The levels of calcium,phosphorus and magnesium as well as intact parathyroid hormone(iPTH)in the sera were tested.Results Positive autoantibodies against parathyroid tissue were demonstrated in 10 patients(38%)with sIHP,significantly higher than that of in genealogical members(10%,?~2=13.42,P

OBJECTIVETo evaluate the anatomy of femoral tunnels created by simulated transtibial technique in double-bundle anterior cruciate ligament (ACL) reconstruction.

METHODSTwo tibial tunnels, anteromedial (AM) and posterolateral (PL), were drilled 45?and 55?to tibial plateau respectively. On the femoral side, the AM and PL tunnels were drilled through anteriomedial portal. After the four tunnels were established, the shaft of a reamer was introduced into the joint through tibial tunnel and reached against the lateral wall of intercondylar notch. The position that the reamer shaft can reach was marked and recorded.

RESULTSNeither femoral AM nor PL tunnel opening can be fully or partially reached by the reamer shaft through the tibial AM tunnel in all cases. The evaluation through the tibial PL tunnel showed that only in 8 of 50 cases (16%) the femoral AM tunnel opening and in 4 cases (8%) the PL opening can be fully reached. On the other hand, in 12 cases (24%) the femoral AM tunnel opening and in 10 cases (20%) the PL opening can be partially reached by the shafts through the tibial PL tunnel.

CONCLUSIONThe result strongly suggests that transtibial technique is not well competent for femoral tunnel drilling in anatomic double-bundle ACL reconstruction as we have hypothesized.
