Objective To investigate the prognosis of cervical intraepithelial neoplasia (CIN) Ⅱ and Ⅲ after being treated by microwave coagulation, loop electrosurgical excision procedure (LEEP) and cold knife conization. Methods From March 2000 to February 2006, 289 patients with CIN Ⅱ or Ⅲ diagnosed by colposcopic biopsy were treated and followed up according to consensus guidelines for the management of women with CIN. Results Totally 233 of the 289 patients (80.6%) completed the follow-up (3-56 months with a mean of 11.8). Among them, 77.7% (181/233) received treatment; the other 22.3% (52/233) did not. In the 181 patients who received treatment, the lesion disappeared in 160 (88.4%) cases, during the follow-up; while in those who did not received treatment, the CIN was cured spontaneously in 63.5% (33/52; ?2=17.664, P=0.000). The prognosis of CIN Ⅱ was similar among the patients who were treated with microwave coagulation, LEEP, or cold knife conization (?2=0.008,P=0.996). In addition, in the patients with CIN Ⅲ, the prognosis after cold knife conization was not significantly different from that after LEEP (?2=0.017,P=0.897). Conclusions The management of CIN Ⅱ and Ⅲ may increase the cure rate. However, the three therapeutic methods produce similar prognosis.

Objective To evaluate the changes in the expression of acetylated histone H3 (Ac-H3) and deacetylase silent information regulator 1 (SIRT1) in dorsal root ganglions in a rat model of negative phenotype neuropathic pain.Methods Forty-eight male Sprague-Dawley rats,weighing 250-300 g,were randomly divided into 2 groups (n =24 each):sham operation group (group S) and C-fiber dysfunction group (group CFD).The rats were anesthetized with 10％ chloral hydrate 3 ml/kg.C-fiber dysfunction was induced by exposing sciatic nerve to 8％ capsaicin for 30 min in group CFD.The thermal withdrawal latency (TWL) and mechanical withdrawal threshold (MWT) were measured before and on 1,3,7 and 14 days after CFD.Six rats were then sacrificed at each time and the lumbar segments (L5) of the dorsal root ganglions were removed for detection of SIRT1 mRNA expression (by RT-PCR) and Ac-H3 and SIRT1 protein expression (by Western blot).Results Compared with group S,TWL was significantly increased at 1,3,7 and 14 days after CFD,SIRT1 mRNA and protein expression was up-regulated and Ac-H3 expression was down-regulated at 3,7 and 14 days after CFD (P ＜ 0.05),while no significant change was found in MWT at each time point in group CFD (P ＞ 0.05).Conclusion The mechanism of negative phenotype neuropathic pain is related to up-regulation of deacetylase SIRT1 expression and decreased acetylation of histone H3 in rat dorsal root ganglions.

Objective: In this paper the pharmacodynamical mechanism of Heat Asthma Formula(HAF)(Herba Ephedrae, Rhizoma pinelliae, Flos Lonicerae, etc) in the treatment of bronchial asthma was discussed. Methods: By means of the radio labelled aglycone, applying phlogistic medium TXB2, ? receptor on bronchus and cyclic nucleotide (cAMP/cGMP) in lung tissue used as observed targets. Results: The results showed HAF could inhibit the release of phlogistic medium TXB2, improve the conjugate rate of ? receptor, adjust the proportion between cAMP and cGMP. Conclusion: The treatment on bronchial asthma of “Heat Asthma Formula” was perhaps concerned with above mentioned contents.

Objective To evaluate the relationship between recurrence of cryptogenic ischemic cerebrovascular disease (CICVD) and patent foramen ovale (PFO),as well as to access the clinical significance of PFO in ischemic cerebrovascular disease.Methods Consecutive patients with CICVD aged 15 to 70 years who were hospitalized in Department of Neurology,Xuanwu Hospital Capital Medical University from January 2008 to March 2011 were prospectively investigated.Identified by transesophageal echocardiography,patients were divided into two groups with respect to outcome:PFO group and non-PFO group.The recurrence of cerebral ischemic events was compared between the two groups after neurological follow-up.Results A total of 91 patients were recruited,including 57 patients with PFO and 34 patients without PFO.The follow-up period of two groups was 695 (506,1142) d.The recurrence rate at 15 months in patients with PFO (24.5％ (12/49)) was higher than those without PFO (6.9％ (2/29),x2 =4.391,P =0.036).Cum hazard curve indicated that recurrence risk of cerebral ischemic events in patients with CICVD in PFO group was higher than that of patients in non-PFO group during the follow-up period (P =0.044).Cox model used for multivariate survival analysis indicated that PFO was a risk factor for cerebral ischemic event recurrence among patients with CICVD (OR =4.159,95％ CI 1.178-14.689,P =0.027).Conclusions PFO is associated with increased recurrence risk of cerebral ischemia in CICVD patients.In addition,PFO may be a significant factor for ischemic cerebrovascular disease.

Objective To analyze the risk factors for patients with cryptogenic ischemic cerebrovascular disease (CICVD) and patent foramen ovale (PFO), as well as to evaluate the relationship between common risk factors and PFO in cerebral ischemia. Methods Consecutive patients with CICVD aged 15 to 70 years who referred to Department of Neurology, Xuanwu Hospital, Capital Medical University from January 2008 to July 2011 were investigated. Identified by transesophageal echocardiography, they were divided into PFO group and non-PFO group with respect to outcome. The common risk factors of cerebral ischemic between 2 groups were compared. The relationship between these risk factors and PFO was analyzed. Results A total of 102 patients were investigated, including 61 patients (59.80%) with PFO and 41 patients (40.20%) without PFO. Positive family history of ischemic cerebrovascular disease proportion in PFO group (31.1%)was higher than that in non-PFO group (9.8%) (P=0.011). There was no significant difference in other observed indicators (P>0.05). Positive family history of ischemic cerebrovascular disease correlated with PFO among CICVD patients (r=0.251, P=0.011). Conclusion PFO was not only more common in CICVD patients, but also correlated with positive family history of ischemic cerebrovascular disease.
