Objective To observe the effect of acupuncture on cerebral glial fibrillary acidic protein(GFAP)expression of brain injury caused by intrauterine infection in neonatal rats.Methods Forty-three Wistar pregnant rats were divided into 2 groups:lipopolysaccharide(LPS)(n=35)and normal saline(n=8).Pregnant rats were consecutively injected intraperitoneally with LPS(450 ?g/kg)or saline on gestation 17 d and 18 d.LPS group were randomly divided into acupuncture group and model group.Acupuncture group were given acupunctured from 7 d to 21 d.GFAP expression was assayed with immunohistochemical technique.Results The number of GFAP immunoreaction(IR)strongly-positive neurons in the cerebral white matter was more in acupuncture group,less in model group and only very weakly IR-positive neurons were found in normal saline group.Conclusion Acupuncture can up-regulate the expression of GFAP in the cerebral white matter,which may contribute to the effect of acupuncture in improving brain injury caused by intrauterine infection.

Objective To investigate the features and risk factors associated with lymph node metastasis in colorectal neuroendocrine neoplasm.Methods Clinical and pathological data of 63 patients with colorectal neuroendocrine neoplasm treated in Yinzhou People's Hospital between June 1997 to December 2012,were analyzed retrospectively.Comparisons of categorical data and univariate analysis of risk factors of lymph node metastasis were conducted by x2 test,multivariate analysis was conducted by Logistic regression analysis.Results Of the 63 patients the rate of regional lymph node metastasis was 30％ (19/63) with 58％ limited to para-intestinal lymph nodes in 11 cases,26％ limited to mesenteric lymph nodes in 5 cases,and 16％ limited to mesenteric root central lymph nodes in 3 cases.No metastasis exceeding central lymph nodes was observed.According to univariate analysis,tumor size,depth of invasion,ulceration in mucous membrane,invasion of lymphatic vessel and pathological grading suggested by WHO were related to regional lymph node metastasis (P ＜ 0.01).Multivariate regression analysis revealed that tumor size,invasion of lymphatic vessel and pathological grading were independent risk factors for lymph node metastasis in colorectal neuroendocrine neoplasm (P ＜ 0.05).Conclusions Colorectal neuroendocrine neoplasm with larger tumor size,invasion of lymphatic vessel or higher grade (G2,G3) has high risk of regional lymph node metastasis.

Aim To investigate the neuroprotective effects of osthole(Ost)on the primary cultured cortical neurons transfected with APP595/596 gene and its underlying mechanism.Methods Neonatal mouse cortical neurons were transfected with APP595/596 gene to establish AD cell models for the further study.Then,the cell viability was detected by CCK-8 assay,and the leakage of lactate dehydrogenase(LDH)was assayed by LDH kit to evaluate the injury degree.Transferase-mediated nick end labeling(TUNEL)was used to evaluate the cell apoptosis.The expression of β-amyloid peptide(Aβ)and β-site APP cleaving enzyme 1(BACE1)was measured by immunofluorescence,while the miRNA-107 was measured by RT-PCR.Results Compared to model group,Ost could significantly improve the neurons viability,decrease the LDH release and prevent the apoptosis.Ost also inhibited the expression of Aβ and BACE1 at protein level,while enhanced the expression of miRNA-107 at gene level.Conclusion Ost plays a neuroprotective role in neurons transfected with APP595/596 gene in part through up-regulating miRNA-107.

OBJECTIVETo observe the effects of Dachengqi Granule (DCG) in the recovery of gastrointestinal function and the condition of patients in the perioperative period of total laparoscopic hysterectomy.

METHODSTwo hundred and one patients received total laparoscopic hysterectomy were assigned to 2 groups, the treated group (103 cases) was orally administered DCG twice, 9 g at 4:00 pm, one day before operation and 6 g at 16 h after operation, while to the control group, enema with 400 mL of soap solution at 8:00 pm one day before operation and acupoint ST 36 injection with 1 mL neostigmine at 16 h after operation were given.

RESULTSTotal laparoscopic hysterectomy was accomplished successfully in all patients, no need to receive open abdominal operation, and with no post-operational complications. In the treated group, the operation time was (116.8 +/- 29.7) min, the operative blood loss was (141.6 +/- 25.1) mL, the post-operative temperature was (37.38 +/- 1.39) degrees C, while those in the control group were (119.6 +/- 28.4) min, (150.6 +/- 22.1) mL, and (37.55 +/- 0.43) degrees C, correspondingly, showing insignificant difference between the two groups (P > 0.05). The white blood cell count on the 1st day after operation was (11.18 +/- 2.93) x 10(9)/L in the treated group, and (12.57 +/- 3.55) x 10(9)/L in the control group (P < 0.01); time for post-operative aerofluxus in them was (35.66 +/- 5.72) h, and (41.77 +/- 6.06) h; time for post-operative defecation (48.47 +/- 18.97) h, and (54.81 +/- 21.30) h, respectively, all showed statistical difference between the two groups (P < 0.01 or P < 0.05).

CONCLUSIONAdministering DCG before and early after operation can effect better than pre-operational enema in ensuring the gynecological operation progression smoothly, and it could also promote the recovery of post-operational gastrointestinal function and improve patients' condition in the perioperative period.

AIM: To observe of cataract phacoemulsification and intraocular lens implantation in patients with postoperative tear film, and to explore its clinical significance.
METHODS: A total of 106 patients ( 140 eyes ) undergone phacoemulsification were randomly chosen. Subjective dry foreign body sensation were observed at six nodes of period 1d, 1, 2, 3wk, and 1mo. Corneal fluorescein ( FSC ) , basal tear secretion ( SIT ) and tear film break-up time ( BUT) were used to detect functional changes of the tear film. And the correlation between tear film stability and corneal sensitivity was analyzed.
RESULTS: Dry eye cumulative score of postoperative 1d, 1, 2wk was higher than preoperative ( t= 8. 53, P=0.000;t=6. 27, P=0. 000; t=9. 02, P=0. 000). There was no significant difference in dry eye cumulative score at postoperative 3wk, 1mo compared with preoperative ( t=1.91, P= 0. 824; t= 1. 27, P= 0. 069). Corneal epithelial fluorescein staining points of postoperative 1d, 1, 2wk were increased compared with preoperative (t=11. 64, P=0. 000;t=9. 61, P=0. 000; t=8. 87, P=0. 001). There was no significant difference in corneal epithelial fluorescein staining points of postoperative 3wk and 1mo compared with preoperative (t=2. 52, P=0. 746; t=1. 16, P=0. 094). Corneal sensitivity detection values of postoperative 1d, 1, 2wk were significantly higher than that of preoperative (t=9.61, P=0.000;t=9.27, P=0.000;t=11.39, P=0.024), and there was no difference postoperative 3wk and 1mo compared with preoperative (t=1. 19, P=0. 562;t=2. 17, P=0. 501).
CONCLUSION: Phacoemulsification with intraocular lens implantation will reduce the tear film stability in the short term, but after a long rest will be improved to a certain extent.

This study is to evaluate the effects of Shenmai injection on the temporal alterations of action potential (AP), early afterdepolarization (EAD) and delayed afterdepolarization (DAD) in papillary muscles. The action potentials were recorded by a glass electrode. APD at 90% repolarization (APD9 ) was measured, and spontaneous EAD and DAD were observed. The results show APD90 was significantly prolonged in model group compared with sham-operated group, whereas it was remained unchanged in Shenmai injec- tion treatment group and amiodarone group. The spontaneous EADs and DADs were frequently visible in model group. In conclusion, EAD, DAD and trigger activities increase gradually during pathological progression of rat cardiac hypertrophy, and Shenmai injection could improve the action potential change in rat cardiac hypertrophy.
