OBJECTIVETo evaluate the key indicators in the pituitary-target gland axes in the animal model of Shen-yang deficiency syndrome (SYDS).
METHODSThe 8 biological indicators [thyroid stimulating hormone (TSH), 3, 3', 5-triiodothyronine (T3), thyroxine (T4), luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone (T), adrenocorticotropic hormone (ACTH), and cortisol (CORT)] in the pituitary-target gland axes were grouped using factor analysis. Then the sensitivity of every indicator was calculated according to the sensitivity function defined in this paper, so as to find all the most sensitive indicators in every group as key indicators of SYDS.
RESULTSThe key indicators in the early period of SYDS were T, LH, T4, and CORT. The key indicators in the middle period were LH,T, CORT, and ACTH. The key indicators in the late period were LH, T, CORT, and FSH.
CONCLUSIONST, LH, and CORT were the common key indicators of the three periods, and other different key indicator of SYDS in the early, middle and late period were T4, ACTH, and FSH respectively, which changed from the thyroid axis to the adrenal axis and then to the gonadal axis as the period changed. The key indicators in the late period were mainly in the gonadal axis, showing gonadal dysfunction in the late period.

OBJECTIVETo evaluate the efficacy of three categorized formulas for tonifying Shen yang, i.e. Shenqi Pill (SP), Yougui Pill (YP), and Yougui Drink (YD) based on rough set, thus exploring the law of compatibility between the core herbs and the edge herbs as well as the law of compatibility between the yang-tonifying herbs and the yin-tonifying herbs in the core herbs.
METHODSThe rats were divided into the normal group, the Shen-yang deficiency model group, and the original prescription group, the core herbs group, and the edge herbs group of this three categorized formulas for tonifying Shen yang, 11 groups altogether. Thyroxine (T4), cortisol (CORT), and testosterone (T) were detected respectively. The decision rules model based on rough set was set up, the interactions between various herbs were analyzed according to the decision rules.
RESULTSThere were synergies between yam and cinnamon, yam and aconite, as well as yam and wolfberry. Poria alisma, Cortex Moutan, and oriental waterplantain tuber had no effect themselves, but they had synergistic effects with the core herbs in SP. Angelica had a certain effect itself, but its functions were different to different core herbs in YP. Licorice had no effect itself, and it was antagonistic with the core herbs in YD.
CONCLUSIONSThe compatibility of core herbs of categorized formula for tonifying Shen yang should focus on benefiting both yin and yang, as well as mutual rooting of yin-yang. Appropriate edge herbs should be chosen for compatibility according to different core herbs. The decision rules model based on rough set has a good prospect in exploring the law of compatibility of the categorized formulas.

OBJECTIVETo review the results for minimally invasive aortic valve replacement (AVR) through a 5 cm right anterolateral thoracotomy.
METHODSFrom July 2009 to September 2011, 101 consecutive patients with isolated aortic valve disease (degenerative in 37 patients, rheumatic in 21 patients, congenital in 37 patients, endocarditic in 3 patients and aorta-arteritis in 1 patients) underwent AVR through the right anterolateral thoracotomy approach in the third intercostal space with a groin incision for femoral connection of cardiopulmonary bypass. The mean age was 45.7 years (ranging from 17 to 71 years). Sixty patients were male.
RESULTSOperations were successfully performed in all but 1 patient (1.0%) who required intraoperative conversion to full sternotomy. Mean duration of cardiopulmonary bypass time and aortic cross-clamp time was (88 ± 24) minutes and (55 ± 18) minutes, respectively. Thirty-day mortality was 1.0% (1/101), this patient was found difficult in weaning off cardiopulmonary bypass and exhibited severe coronary artery plaque, although bypass graft was carried out immediately, the patient died of severe low cardiac output syndrome finally. No blood products were needed in 83.2% patients. Follow-up was performed in all patients at an average of (16 ± 7) months postoperatively. A good recovery was obtained in all patients except one who died of multiple organ failure caused by massive cerebral infarction 38 days after surgery.
CONCLUSIONSMinimally invasive aortic valve replacement though the right anterolateral thoracotomy approach is safe and feasible, with good cosmetic results and rapid postoperative recovery. It is worthy of clinical elective application.

Objective:To retrospectively analyze the long-term survival (10-15 years) and late toxicity of nasopharyngeal carcinoma (NPC) patients after intensity-modulated radiotherapy (IMRT), aiming to provide reference for the optimal treatment of NPC.Methods:132 patients with NPC who were treated with IMRT in Sichuan Cancer Hospital from 2003 to 2009 were recruited. Among them, 3 patients were classified as stage Ⅰ, 22 cases of grade Ⅱ, 61 cases of grade Ⅲ, 43 cases of Ⅳ A and 3 cases of Ⅳ B, respectively. The median dose was 73.37Gy (66 to 85Gy), divided into 33 times. Twenty patients received radiotherapy alone, 112 cases of concurrent radiochemotherapy. The survival rate was calculated by Kaplan-Meier method and log- rank test. Univariate prognostic analysis was performed. Cox model was used to conduct multivariate prognostic analysis. The late radiation toxicity was evaluated by RTOG/EORTC criteria. Results:The median follow-up duration was 128 months (range, 3 to 191 months). The 10-and 15-year local control rates of NPC patients were 86.0% and 79.9%. The disease-free survival rates were 72.5% and 63.2%, and the overall survival (OS) rates were 65.2% and 57.1%. The local recurrence rate was 12.1%, and the distant metastasis rate was 16.7%. A total of 53 patients died, of whom 15 patients died of local recurrence, 20 patients died of distant metastasis and 18 patients died of other diseases (pneumonia, intracranial hemorrhage and accident, etc.). The 10-and 15-year non-tumor-related mortality rates were 11.3% and 13.6%. Univariate analysis showed that age, smoking habit, lactate dehydrogenase (LDH), T stage and clinical stage were the independent prognostic factors of OS in NPC patients. Multivariate analysis demonstrated that LDH, T stage and synchronous chemotherapy were the prognostic factors of OS in NPC patients. The incidence of gradeⅠ-Ⅱ late radiation injury (hearing impairment, dysphagia, dental caries and xerostomia) was 90.4%, and 8.5% for grade Ⅲ-Ⅳ late radiation injury (skin fibrosis, hearing impairment and radiation brain injury).Conclusions:The 10-and 15-year OS of NPC patients treated with IMRT is relatively high. With the prolongation of survival, the non-tumor-related mortality rate is increased. Distant metastasis is the main cause of treatment failure. The main late injuries include grade Ⅰ/Ⅱ hearing impairment, dysphagia, dental caries and xerostomia.

OBJECTIVETo observe the effect of exogenous phophatase and tensin homolog deleted on chromosone 10 (PTEN) gene transfer via recombinant adenoviruses on the proliferation of human airway smooth muscle cells (HASMCs) in vitro and investigate the possible mechanisms.
METHODSWith a recombinant adenovirus vector containing PTEN (Ad-PTEN) constructed using the pAdxsi system, PTEN gene was transiently transfected into HASMCs and the transfection efficiency was determined by fluorescence microscope. RT-PCR and Western blotting were performed to detect the expression of PTEN mRNA and protein in the infected cells. MTS/PMS assay was used to analyze the proliferation of HASMCs, and the cell cycle changes of the transfected cells were evaluated by flow cytometry with PI staining. The expression levels of Akt and p-A kt proteins were detected by Western blotting, and P21 mRNA expression determined by RT-PCR.
RESULTSThe recombinant adenovirus Ad-PTEN showed a wild-type PTEN gene transfer efficiency of 98% at the multiplicity of infection (MOI) of 100. RT-PCR and Western blotting showed that infection with the recombinant adenovirus resulted in PTEN overexpression in the HASMCs, causing also increased ratio of G(0)/G(1) cells and proliferation inhibition of the ASMCs. The overexpression of PTEN significantly decreased the expression level of p-Akt but increased P21 mRNA expression.
CONCLUSIONThe recombinant adenovirus containing PTEN can be successfully transfected into HASMCs cultured in vitro, resulting in PTEN overexpression at both the mRNA and protein levels. PTEN overexpression can efficiently inhibit the proliferation of HASMCs possibly through the PI3K/PKB/AKt and P21 pathways.

OBJECTIVETo compare the positive rates and complications of ultrasound-guided transrectal and transperineal prostate biopsies.
METHODSWe retrospectively analyzed 156 cases of ultrasound-guided transrectal (n = 97) and transperineal (n = 59) prostate biopsy, and compared the positive rate and post-biopsy complications between the two approaches.
RESULTSThe positive rates in the transrectal and transperineal groups were 48.4% and 44.1%, respectively, with no significant difference between the two approaches according to different PSA levels (P >0.05). No statistically significant differences were observed between the transrectal and transperineal groups in the post-biopsy incidence rates of such complications as hematuria (54.6% vs 42.4%, P >0.05), lower urinary tract symptoms (17.5% vs 22.0%, P >0.05), dysuria (9.3% vs 6.8%, P >0.05), and acute urinary retention (7.2% vs 6.8%, P >0.05). However, the incidence rates of post-biopsy infection and rectal bleeding were remarkably higher (15.5% vs 3.4%, P<0.05 and 50.5% vs 3.4%, P >0.01) while that of perineal swelling markedly lower in the former than in the latter (3.1% vs 13.6%, P <0.05).
CONCLUSIONTransrectal and transperineal biopsies are both effective for the diagnosis of prostate cancer. Since their complications vary, the choice between the two methods depends on the specific condition of the patient.

OBJECTIVETo present a new method for correction of prominent malar complex by L-shaped osteotomy through an intraoral incision.
METHODSBased on the anatomical characteristics of the malar complex, we designed a new L-shaped osteotomy for malar eminence reduction. The procedure includes oblique incision of the upper part of the mala, vertical incision of the anterior part of the mala and "greenstick" fracture of the zygomatic arches. According to the severity of malar prominence, we resect part of the anterior-inferior part of the mala and lower the malar complex.
RESULTSThis method was used in 39 patients with prominent malar complex. Of them, 32 were symmetrical and 7 were unsymmetrical. All the patients obtained good results.
CONCLUSIONL-shaped osteotomy for correction of prominent malar complex is a relatively ideal surgical method with the advantages of simpler manipulation, fewer complications, better result, and ensuring the intactness of the structural characteristics of the malar complex.

OBJECTIVETo investigate the changes in human airway smooth muscle cell (HASMC) migration and related signaling pathway after interference with PTEN gene expression.
METHODHASMCs were infected with an adenovirus vector and RNA interference vector of human PTEN gene to establish the cell model with PTEN gene over-expression (Ad-GFP-PTEN-HASMC) and one with PTEN gene silencing (Ad-shPTEN-HASMC), using Ad-GFP-infected and a blank cells as the negative controls and LY294002 as the positive control. Fluorescence microscopy and flow cytometric analysis were used to evaluate the transfection efficiency, and Western blotting was performed to examine the expression of PTEN and the activation of AKT and ERK1/2 signal pathway. Transwell assay and wound healing assay were used to assess the migration of HASMCs.
RESULTSThe adenovirus over-expression vector and RNA interference vector significantly affected the expression of human PTEN gene. Up-regulation of PTEN gene resulted in a slow-down of the HASMC migration, an inhibition of PI3K/AKT signal pathway at the protein level but no changes in Ras-Raf-MEK1/2-ERK1/2 signal pathway. Down-regulated PTEN gene expression, however, was not associated with an enhancement of HASMC migration, but activated PI3K/AKT signal pathway and inhibited Ras-Raf-MEK1/2-ERK1/2 signal pathway.
CONCLUSIONUpregulation of PTEN gene can effectively inhibit airway smooth muscle cell migration, the effect of which is probably mediated by the PI3K/AKT pathway.
