Recently the combination of acupuncture with assisted reproductive technology (ART) to increase the outcomes of ART is being widely studied. In this article, the literatures concerning random controlled clinical trials since 2002 are reviewed and the designs of the trials, especially the timing of acupuncture, are evaluated. Over the past 5 years, the related clinical trials have primarily showed that acupuncture done immediately before and after embryo transfer might increase the assisted reproduction rates, but still requiring further high quality trials with large samples; in addition, different stimulation modes could produce different result, and so far there has not been a consensus as to the optimal time-point for the acupuncture intervention during the in vitro fertilization-embryo transfer (IVF-ET) course. Since the effects of acupuncture change with women's endocrine cycles, it is important and possible to make a breakthrough in ART outcomes if acupuncture is performed at a suitable time point during the cycle of IVF/ET combined with ART.

AIM: To explore the effects of chromodomain protein 8 (CBX8) on the proliferation and apoptosis of human glioma cells.METHODS: The expression of CBX8 in the tissues and cells was detected by Western blot and RT-qPCR.The overexpression (Flag-CBX8) and silencing (sh-CBX8) vectors of CBX8 were constructed and transfected into glioma T98G cells and U87MG cells.The cell proliferation was detected by MTT assay and BrdU staining.The cell apoptosis was analyzed by flow cytometry.The protein expression of Rb/E2F1 was detected by Western blot.RESULTS: Compared with normal brain tissues and astrocytes, the expression of CBX8 was increased in the glioma tissues and glioma cells.Overexpression of CBX8 promoted the cell proliferation, inhibited the cell apoptosis, and upregulated the protein levels of Rb/E2F1.On the contrary, silencing of CBX8 inhibited the cell proliferation, promoted the cell apoptosis, and decreased the protein levels of Rb/E2F1 in the T98G cells and U87MG cells.Moreover, the expression of cyclin D1 and Bcl-2/Bax ratio were reduced after transfection with sh-E2F1 in the T98G cells and U87MG cells.CONCLUSION: CBX8 may regulate the proliferation and apoptosis of glioma cells through Rb/E2F1 pathway.

OBJECTIVE Approach the cause of esophageal perforation and the analysis of diagnosis, therapy and its outcome in this disease. METHODS We retrospectively review 11 patients of esophageal perforation between1997 and 2004 in our department. There were 9 cases were taken out foreign bodies from their esophageal, another 2 cases haven't been found any foreignbodies and 1 of 2 was caused by iatrogenic reasons. Perforation occurred in the cervical esophagus was 4, and in the thoracic esophagus was 7. Their symptoms were dysphagia or pain, retrosternal-pain, dyspnea, subcutaneous emphysema, fever, hematemesis or melena. RESULTS 7/11 cases visited the clinic during 24 hours after foreign-body occured, 4/11 cases visited after 24 hours and the last visited clinic on 27th day late. Dysphagia was the most common presenting symptom specially with pain in eating, noted in 9 cases (81.8 %); retrosternal-pain and fever were noted in 8 cases (72.7 %), subcutaneous emphysema in 5 (45.5 %), dyspnea in 2 (18.2 %), hematemesis and melena.in 1 (9.1 %). 5 cases were died and the common mortality was 45.45 % (5/11). The mortality in primary repair with surgery treatment was 66.7 % (2/3); the mortality in conservative management was 37.5 % (3/8). The mortality of the perforation in cervical esophagus was 25 % (1/4), in thoracic esophagus was 57.14 % (4/7). The mortality of the visit time in 24 hours was 28.57 % (2/7),and out of 24 hour was 75% (3/4). CONCLUSION Sophageal perforation is usually caused by foreign body or iatrogenic in ENT-Head&Neck surgery. The esophageal perforation will been cured that decided in early visiting, taking away of foreign-boby, the right choice of antibiotic, nutritional support, primary healthy statement of esophagus. We regard that should perform non-operational conservative therapy in the patients who resulted in esophageal perforation except abscess or remain causing by foreign body. And the high risks in mortality of the repairing in surgery should been noticed.

Objective To detect the expression of the transcription factor CCAAT/enhancer-binding protein alpha (C/EBP-α) in the epidermis of psoriasis vulgaris lesions,and to investigate its correlation with abnormal keratinocyte proliferation and disease severity.Methods Biopsy specimens were obtained from the lesions of 30 patients with psoriasis vulgaris and normal skin of 30 healthy human controls.A two-step immunohistochemical procedure was performed to detect the expressions of C/EBP-αt and Ki-67 in these specimens,and Western blot to quantify the expression of C/EBP-α.The proliferation index of keratinocytes was calculated according to the expression intensity of Ki-67.Statistical analysis was carried out by using the SPSS 17.0 software,and Pearson correlation analysis was conducted to assess the relationship of C/EBP-α expression level with proliferation index of keratinocytes and psoriasis area and severity index (PASI) score.Results C/EBP-α was predominantly expressed in the cytoplasm of keratinocytes,while Ki-67 in the nuclei of keratinocytes.Compared with the normal skin,the psoriatic lesions showed a significantly lower expression of Ki-67 (t =7.82,P < 0.05),but higher proliferation index of keratinocytes (t =4.54,P < 0.05).The expression level of C/EBP-α was negatively correlated with the proliferation index of keratinocytes and PASI score in the patients (both P < 0.05).Western blot also showed an obvious decrease in the expression of C/EBP-α in psoriatic lesions.Conclusions The expression of C/EBP-α is decreased in lesions of psoriasis vulgaris,which might be involved in the pathogenesis of psoriasis vulgaris.
