Objective To investigate the effect of edaravone and early rehabilitation on neurological deficit in patients with acute cerebral infarction. Methods Fifty patients with acute cerebral infarction were enrolled in this study. Fifty patients were grouped using the random number table method as the subject of this study. A single group of 25 patients treated with edaravone treatment, combined group of 25 patients with edaravone and early rehabilitation treatment, compared the two groups of patients with acute cerebral infarction neurological deficit score, quality of life score and clinical efficacy. Results The scores of neurological deficits after treatment were (14.24 ± 3.42), which were significantly lower than those in the single group (P<0.05). The quality of life scores of the patients in the combined group were (104.24 ± 3.25) The total effective rate was 92.00％ in the combined group, which was significantly higher than that in the single group (64.00％, P<0.05). Conclusion Edaravone and early rehabilitation therapy in patients with acute cerebral infarction can significantly improve the neurological function of patients, the effect is more significant.

After the research of PLA2R1 and its antibodies, Thrombospondin type-1 domain-containing 7A and its antibodies to membranous nephropathy (MN) has made a new understanding.Some researches have reported that the antibodies of PLA2R1 and THSD7A were mutually exclusive in MN, because THSD7A was found in PLA2R1-negative MN patients.But the latest researcher showed that these antibodies can be both positive in MN patients.Similar to the function of PLA2R1, THSD7A can assist clinical diagnosis, treatment, and monitor of MN.In contrast to PLA2R1, THSD7A was also highly expressed on both human and murine podocytes.We can use the mice model to study the pathogenesis of THSD7A-associated MN in the future.In this review, we describe the structure and function of Thrombospondin type-1 domain-containing 7A and its autoantibodies, highlight its role in MN and suggest possible aspects of its future clinical application.

Objective To evaluate the clinical efficacy of laparoscopy combined with colonoscopy for small colorectal space occupying lesions (equal or less than 3 cm). Methods From January 2010 to January 2015,a total of 41 cases of small colorectal space occupying lesions (equal or less than 3 cm)were treated under general anesthesia with laparoscopic surgery combined with colonoscopy.The patients were placed at the lithotomy position.After the establishment of pneumoperitoneum,injection of methylene blue for staining was carried out under colonoscopy. Laparoscopic titanium clipping positioning was conducted, and then the colonoscope was withdrawn.According to the intraoperative frozen pathological results,bowel resection surgery or colorectal surgical resection was selected. Results All the 41 cases of laparoscopic combined with colonoscopic surgery were successfully completed, with no conversion to laparotomy.There were 9 cases of preoperative diagnosis of precancerous lesions,6 of which were found neoplasia in the colon epithelium with intraoperative pathological diagnosis,with 3 cases of Tis adenocarcinoma.Among 32 cases of preoperative diagnosis of stage 0 -Ⅰ colorectal cancer,there were 29 cases of intraoperative and postoperative diagnosis of stage Ⅰ (23 cases of T1 N 0 M0 adenocarcinoma and 6 cases of T2 N 0 M0 adenocarcinoma)and 3 cases of stage Ⅲ (T2 N 1 M0 adenocarcinoma).Two cases were multiple lesions.Bowel resection was performed in colon intraepithelial neoplasia and Tis lesions of colorectal cancer,while resection of colorectal cancer was conducted in stage T1 -T2 colorectal cancer.Two patients with colonic epithelial neoplasia were followed up for 9 and 12 months,without recurrence.The remaining 39 cases were followed up for 24 -49 months,with a median of 38.6 months. Among the 35 cases of colorectal cancer,colonoscopy detected local recurrence in 1 case of T2 N 1 M0 adenocarcinoma (stage Ⅲ)after 34 postoperative months.No metastasis was found in all the patients. Conclusion Laparoscopy combined with colonoscopy for small diameter (equal or less than 3 cm)benign tumor or stage Tis -T2 malignant colorectal cancer has advantages of both endoscopy,especially suitable for difficultly located or removed lesions,which can improve the positioning precision and surgical safety.

Objective Cesarean scar pregnancy(CSP)is a specific ectopic pregnancy with the two -child policy opened,the rate of cesarean section deliveries had increased exponentially,and the rate of CSP had increased. Due to lacking typical syndromes,it is easily misdiagnosed or causing massive haemorrhage during abortion operation, even threat to patients'lives,therefore,early diagnosis and treatment is essential to avoid severe complication.Although there are a variety of treatment methods for CSP,there has been no standardized strategy for its treatment at present. The article is a review of the pathogenesis,diagnosis and treatment of CSP.

Objective To investigate the effect of Sufentainil on myocardial ischemia-reperfusion injury and caspase-3 to rat heart. Methods Ninety Wistar rats weighing 200-300g were randomly divided into 3 groups(n=30):sham group(group S), ischemia-reperfusion group (group I/R)and Sufentainil group (group SF). Each group was divided into 3 subgroups according to the time phases at 30, 60 and 120min(n=10).In group I/R and group S the animals were received normal saline intravenously. In group SF sufentainil 5μg/kg NS 20ml was given. After 24 h, all animals were anesthetized with intraperitioneal 20% urethane 1 mg/kg, intubated and mechanically ventilated. The chest was opened and heart exposed via thoracotomy.In group S , left artery anterior descending artery(LAD) was not ocluded. While in I/R and SF group myocardial ischemia was introduced by clamping LAD for40 min. The animals were killed at 30, 60 and 120 min of reperfusion respectively(n=10each). Cardiac tropoin I(cTnI), expression of caspase-3 and apoptosis of cell in heart tissues were measured at the same time.Ultrastructure of myocardium taking the from apex was examined by electron microscopy at the end of 120 min reperfusion. Results Compared with group S, the concentration of cTnI was increased in the other 2 groups(P<0.05).cTnI was significantly lower in group SF than in group I/R(P<0.05). Expression of caspase-3 and apoptosis index induced by myocardial reperfusion were attenuatated in group SF(P<0.05). The damage of myocardial ultrastructure caused by myocardial I/R were also significantly improved in group SF. Conclusion Sufentainil may relieve the heart cellular apoptosis by decreasing caspase-3expressing.

Objective Ryanodine receptor (RyR) is one of the Ca2+ release channels on the intracellular Ca2+ stores. RyR induced-Ca2+ release is activated by the voltage-dependent Ca2+ entry, that is, calcium-induced calcium release (CICR). Intracellular free Ca2+ concentration (ECa2+]i) plays a key role on cochlear function. Our study is to investigate the differential expression of RyR in the developing rat cochlea, and to analyze the relationship between the expression of RyR and auditory functional development. Methods Immature SD rats, which were 1 day (P1), 5 days (P5), 10 days (P10), 14 days (P14), 28 days (P28) after parturition, and adutl rats(5 rats for each age) were included in the study. Frozen cochlea sectioning and immunofluorescence were applied to observe the differential expression of RyR. Results The RyR expression in the Corti's organ increased during the cochlear development. It's not significant that the stain was observed on the hair cells and supporting cells in the Corti's organ of P1 and P5 rats. The appearance of the Corti's organ of P10 rats trended to maturity. In P14 rats the RyR expression on hair cells located in the synaptic area against the afferent or efferent nerve, and the strain on supporting cells was extensive. There was little different between the strain on cochlea of P14 and P28 rats. In postmature rat spiral ganglion neurons (SGN), the RyR expression verged gradually from extensive whole cell soma to the synaptic area near to the plasma membrane. Conclusion The RyR expression peaked the 14th day after parturition, which was close to that in the mature cochlea. The time course of the RyR expression during the cochlear development was coincident with that of the auditory functional development. The RyR expression on both hair cells and SGNs located in the synaptic area near to the plasmolemma, implying that RyR induced-CICR was related to the auditory functions such as neurotransmission. Extensive RyR expression in the soma of SGNs at the early stage possibly involved in apoptosis of SGNs during neuron development.

Numerous pro-apoptotic signal transducing molecules act on mitochondria and provoke the permeabilization of the outer mitochondrial membrane, thereby triggering the release of pro-apoptotic proteins potentially.One of them is much important,which called apoptosis inducing factor(AIF).Upon lethal signaling,AIF released from mitochondria, which translocates, via the cytosol to the nucleus, where it binds to DNA and provokes Caspase-independent chromatin condensation and leading to apoptosis.It has been found gradually that AIF has impotant effect in some malignant cancer cells(such as colorectal carcinoma cell), especially its regulation effect in cell death.Recently some of researches indicate that inducing cell apoptosis by effecting on the releasing or expressing of AIF, has been a new research direction of colorectal carcinoma therapy.

Bronchial asthma is one of the most common children health problems, with still increasing prevalence.Bronchial hyperresponsiveness is a characteristic feature of asthma,and its measurement may provide a useful adjunct in the diagnosis of asthma. Many children with asthma go into long-term clinical remission at adolescence, but bronchial hyperresponsiveness persists in approximately one half of these subjects, so implement the bronchial provocative tests in children with asthma remission may appears very important.
