OBJECTIVE: To discuss the clinical efficacy of adenoidectomy and tonsillectomy for the OSAHS children with sinusitis. METHOD: Reviewing 112 cases of children with OSAHS, in which the 80 patients without chronic sinusitis, 32 ones with chronic sinusitis. Among them, 103 cases of children with adenoidectomy, tonsil resection, 9 cases adenoidectomy only. We did questionnaire survey before and after surgeryand also did post-surgery clinical follow-up. RESULT: The effective rate was 90.0% for the OSAHS children without sinusitis after adenoid and tonsil ectomy surgery, while the effective rate was 46.9% for the ones with sinusitis, the efficiency was significant different in the two groups after surgery; the 16.1% children after tonsil ectomy surgery complained the incidence of pharyngeal foreign body sensation and pharyngeal lymphoid hyperplasia in children was 23.2%. CONCLUSION The efficiency was aviable for the OSAHS children without sinusitis after surgery; The efficiency was not aviable enough for the OSAHS children with sinusitis after surgery, so the latter one need adjuvant drug treatment; We also should be attention to the pharyngeal foreign body sensation and the lymphoid hyperplasia in children after tonsillectomy.

The pathomechanisms of the progression of chronic kidney disease (CKD) include glomerulosclerosis, renal interstitial fibrosis and renal arteriosclerosis. Chinese herbal medicine can delay the progression of CKD by ameliorating the harmful factors of these pathological changes, such as podocyte and slit diaphragm injury, nephrotoxicity of proteinuria, hyperactivity of renin-angiotensin-aldosterone system, cytokines over-expression, tubular epithelial myofibroblast transdifferentiation, hyperlipidemia and hypertension.

OBJECTIVETo detect the changes of the expression of Bax and Bcl-2 gene in the denervated testis, and to explore the possible mechanisms underlying the apoptosis of germ cells induced by testicular denervation at the genetic translation level.

METHODSEighteen mature SD rats (350-375 g) were equally divided into 3 groups: a sham operation group( SO) , a superior spermatic nerve group (SSN) and an inferior spermatic nerve group (ISN) , and the latter two received bilateral surgical removal of the superior spermatic nerve and the inferior spermatic nerve, respectively. The animals were killed I month after the operation. ISH SP-method was used to detect the expression of Bax and Bcl-2 protein.

RESULTSSignificant up-regulation of Bax protein was detected in both the treatment groups 1 month after surgery( P <0. 05) , and the level of Bcl-2 protein remained unchanged.

CONCLUSIONBax gene is involved in the apoptosis of germ cells induced by testicular denervation.

BACKGROUNDIntramedullary nails have been widely used in treating femoral shaft fractures. However, end caps falling into soft tissue intraoperatively may cause trouble to surgeons, prolong operative time and increase radiation exposure. Additionally, difficulties may be encountered when removing nails because of callus formation over the nail tip. We performed a prospective study to compare two types of nails in managing femoral shaft fractures.

METHODSGroup I consisted of seventy-four patients with unilateral femoral shaft fractures treated with cannulated interlocking anatomical femoral intramedullary nails. Group II consisted of seventy-eight patients treated with cannulated interlocking anatomical femoral intramedullary nails with tail wires. The patients' ages, fracture severity, duration of operation, fluoroscopy time, blood loss and falls of end caps into soft tissue were recorded. Nails were removed after fracture healing. The duration of operation and blood loss during nail removal were recorded.

RESULTSThere were no significant differences between groups with respect to age and fracture severity (P > 0.05). End caps fell into soft tissue 17 times in 15 cases in group I and 21 times in 16 cases in group II. An average of seven minutes was spent recovering a lost cap in group I. In group II, all lost caps were recovered immediately. The duration of operation and fluoroscopy time in group II was significantly less than in group I (P < 0.05). Asymptomatic palpable nodules were detected in 4 cases in group II. Nail removals were performed on 58 patients in group I and 69 patients in group II. The duration of operation, blood loss and complications in group II were less than in group I (P < 0.05).

CONCLUSIONIntramedullary nails with tail wires facilitate both fracture fixation and nail removal, which can be used to treat femoral shaft fractures with less radiation exposure, shorter surgical time and fewer complications.

This study was aimed to explore the effects of decitabine on the biological behaviour of U266 cells in vitro so as to provide a new thinking and experiment basis, as well as new evidences for the pathogenesis of multiple myeloma. MTT and colony formation assays were used to evaluate the impact of decitabine on the ability of proliferation of U266 cells; flow cytometry was used to analyze the cell distribution in cell cycle; transwell chamber and matrigel assays were used to observe the ability of migration and invasion. The results indicated that decitabine could significantly suppress the proliferation of U266 cells in time-and dose-dependent manners. The flow cytometric analysis demonstrated that the cells in G(0)-G(1) phase significantly increased while the cells in S and G(2)/M phase decreased. The migration and matrigel invading tests showed that the number of cells moving into under chamber of transwell decreased after U266 cells treated with decitabine. It is concluded that decitabine may act as an effective drug for MM by inhibiting the proliferation, migration and invasion ability, and the specific mechanism needs to be deeply explored.

BACKGROUNDRoutine anteroposterior radiographs of the acromioclavicular (AC) joint with or without weight bearing have limitations in demonstrating the AC joint. Transarticular fixation with Kirschner wire is a treatment choice for AC dislocations. However, percutaneous fixation of the AC joint is technically demanding. The C-arm fluoroscopy can be used as routine intraoperative guidance to facilitate this procedure. The current study aims to introduce new projections, the axial and tangential views of AC joint, to help evaluate the severity of the injury and facilitate the percutaneous procedure.

METHODSThree shoulder specimens were used to find the projection directions of the axial and tangential views of the AC joint by using the digital radiography (DR) unit. The axial and tangential views were taken of 20 adult volunteers by referencing the projection directions determined in the shoulder specimens. The angles showed on the DR system and the angles between the coronal plane of the body and the vertical plane of the flat panel detector (FPD) during taking these radiographs were recorded. The C-arm fluoroscopy unit was used to take the axial and tangential views referencing the angles measured on the DR system. Routine anteroposterior radiographs of the AC joint were taken on the volunteers. The minimal distances from the distal clavicle to the acromion were measured on both tangential and anteroposterior radiographs. The data was statistically analyzed.

RESULTSThe clear axial and tangential radiographs of AC joints of the volunteers were obtained using both DR and C-arm fluoroscopy units. The angles demonstrated on the DR window are (20.8 ± 2.4)° for male and (18.3 ± 2.3)° for female. During taking the axial views, the angles between the coronal plane of the body and vertical plane of FPD are (23.3 ± 3.2)° for male and (20.1 ± 2.4)° for female. During taking tangential views, the corresponding angles are (117.5 ± 3.7)° for male and (113.1 ± 3.3)° for female. On the tangential radiographs, the minimal distance from the distal clavicle to the acromion is (6.1 ± 1.2) mm, wider than the same measurement on the anteroposterior radiographs (P < 0.05). Statistical analyses showed no significant differences in the above-mentioned angles and the minimal distances between the left and right AC joints (P > 0.05). There were no significant differences in the above-mentioned angles between DR and C-arm fluoroscopy units (P > 0.05).

CONCLUSIONSThe axial and tangential radiographs of the AC joint can demonstrate the joint clearly and they can be easily obtained with both DR system and C-arm fluoroscopy unit in similar projection directions.

【Objective】 To observe the regulation of autonomic nerves in blood donors during blood donation by heart rate variability analysis and explore the possible mechanism of donation related vasovagal reaction. 【Methods】 Electrocardiogram (ECG) of 90 blood donors was monitored by Fontaine Ⅰlead during the whole process of blood donation, and the 5-min heart rate variation before, during and after blood donation was analyzed. 【Results】 During the whole process of blood donation, the sympathetic HRV index (LF nu) and the sympathetic and vagal balance ability index (LF/HF) increased, whereas the vagal nerve index (pNN50, RMSSD, HFnu) and heart rate variability index (SDNN, Total power) decreased. For baseline heart rate variability of different blood donors (first-time vs. repeated, male vs. female, 18-24 years old vs. ≥25 years old, <400 mL vs. 400 mL) before blood donation, the pNN50, RMSSD and Total power of 18-24 years old blood donors were higher, but other indicators showed no significant difference. There were differences in HRV indexes of different types of blood donors during blood donation compared with before blood donation. The decrease of pNN50 and HFnu and the increase of LF/HF were larger in experienced blood donors than in first-time blood donors. The decrease of RMSSD was larger in male blood donors than in female blood donors; the change of LF/HF was larger in blood donors aged≥25 years than in blood donors aged 18-24 years; other indicators had no significant difference. 【Conclusion】 Blood donation leads to reflex readjustment of the cardiac autonomic tone: the sympathetic nerve is excited while the vagal nerve is suppressed. The cardiac autonomic nerve function of first-time blood donors, female donors and low-age (18-24 years old) donors to blood donation stress is not fully regulated. Donation related vasovagal reaction may be related to the autonomic nerve regulation function of blood donors.

OBJECTIVETo investigate the changes of CD4T lymphocytes in peripheral blood of patients with follicular lymphoma and its clinical significance.

METHODSBlood samples were collected for detection of whole blood cells, including absolute monocyte count (AMC), absolute lymphocyte count (ALC), hemoglobin (Hb), platelet count (Plt). Age, sex, pathological grade, number of involved lymph nodes, bone marrow involvement (BMI), Ann Arbor stage, B symptoms, serum lactate dehydrogenase (LDH) and serum β-2 microglobulin (β2-MG) were recorded, the prognostic stratification was performed by using FLIPI and FLIPI-2. The T lymphocyte subsets were analyzed by flow cytometry, including the absolute number of CD4T lymphocytes (ACD4C) and the absolute number of CD8T lymphocytes (ACD8C).

RESULTSPatients were with higher Ann Arbor stage, Hb<120 g/L, LDH greater than the upper limit of normal, the number of lymph nodes were involved> 4, the bone marrow was involvement, β2-MG levels were high FLIPI score and FLIPI-2 score, AMC level was higher (P<0.05). There were no significant differences in ACD4C levels among different groups. Patients with AMC≥0.89×10/L showed a shorter progression-free survival (PFS) and a shorter overall survival time (OS) (P=0.010,0.002) as compared with patients with AMC<0.89×10/L. The patients with ACD4C>0.16×10/L had longer progression-free survival and overall survival time, as compared with patients with ACD4C ≤0.16×10/L (P=0.016,0.012). Low ACD4C and high AMC related with shorter PFS and OS (P=0.013, 0.020). Univariate Cox regression analysis showed that age (P=0.026), bone marrow involvement (P=0.017), elevated LDH (P=0.001), β2-MG (P=0.014), FLIPI and FLIP2 score (P= 0.004 and 0.000) related with a shorter PFS. Multivariable Cox regression analysis showed that Hb (P=0.015), elevated LDH (P=0.003), β2-MG (P=0.045), bone marrow involvement (P=0.016) and FLIPI-2 score(P=0.003) related with short OS. ACD4C ≤0.16×10/L was a factor influencing prognosis of FL patients (PFS and OS) (P<0.05).

CONCLUSIONSLow ACD4C levels relatees with poor prognosis of patients with FL, and the ACD4C levels may be an important predictor for FL disease and prognosis.
