Objective:To summarize the drug interactions of haloperidol used in combination with the other drugs to provide refer-ence for safe, reasonable and effective use of haloperidol in clinics. Methods:By retrieving Micromedex? , Pubmed, CNKI and so on, the interactions between haloperidol and the other drugs were summarized and analyzed. Results:The effect of haloperidol was on do-pamine receptors, and haloperidol was mainly metabolized by hepatic cytochrome P450 ( CYP) enzymes. When haloperidol was com-bined with the other drugs, significant interactions of pharmacokinetics and pharmacodynamics were induced by affecting CYP enzymes or dopamine receptor. Conclusion:In clinical practice, the other drugs combined with haloperidol should be reasonable and careful to ensure safe, effective and rational drug use.

OBJECTIVETo analyze the rules for acupoint selection of acupuncture and moxibustion in domestic clinical treatment of perimenopausal syndrome based on data mining technology in modern times.

METHODSThe relevant literature were retrieved from Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI) and Wanfang database on this disease treated with clinical acupuncture and moxibustion in China from 1978 to 2013. The database of acupuncture-moxibustion prescription was set up. The relevant regulations of data mining technology were used to analyze the rules for acupoint selection.

RESULTSTotally, 211 papers, 254 acupuncture-moxibustion prescriptions and 130 acupoints were included. The total frequency of acupoints application was 2193 times, with 14 meridians involved. The utilization of the acupoints in the lower limbs and on the back were 33.0% (723/2193) and 23.8% (521/2193) and those of yin and yang meridians were 51.8% (1136/2193) and 44.0% (965/2193), respectively. The utilization of the specific acupoints accounted for 88.7% (1946/2193).

CONCLUSIONIn clinical treatment of perimenopausal syndrome with acupuncture and moxibustion in modern times, the acupoint selection from involved meridians is the basis, associated with multiple methods of acupoint combination; yin and yang meridians are equally important and the specific acupoints are considered particularly critical in application.

Objective To assess the relationship between pulse wave velocity(PWV) and carotid atherosclerosis by UltraFast imaging.Methods 476 cases from Medical Examination Center of Beijing Friendship Hospital were enrolled in this study.According to intima-media thickness(IMT) of carotid artery,all subjects were divided into two groups:IMT without thickening group (G0) of 283 cases and IMT thickening group (G1) of 193 cases.Through UltraFast imaging,carotid artery PWV was measured,including the PWV at the beginning of the systole(BS) and the PWV at the ending of the systole(ES).Carotid IMT and plaque situation were recorded under gray-scale ultrasound.BS and ES were compared between the two groups.Spearman rank correlation was used to analyse the correlation between IMT of carotid artery and BS,between IMT of carotid artery and ES.Two independent samples t test to compare BS,ES between the two groups.Results BS of G1 and G0 were (6.03 ± 1.33)m/s and (5.51 ± 1.13)m/s,t =-4.571,P =0.000;ES of G1 and G0 were (8.42 ± 2.13)m/s and (7.34 ± 2.02) m/s,t =5.619,P =0.000.BS and ES of G1 were larger those of G0 respectively.BS (r =0.192,P =0.000) and ES (r =0.249,P =0.000) were correlated with the IMT of carotid artery.Conclusions Ultrafast imaging technique can quickly measure the carotid artery PWV.BS and ES of carotid artery can be quick,convenient,safe,noninvasive parameters for evaluating carotid atherosclerosis.

OBJECTIVETo evaluate the effect of different preparation methods on the encapsulation efficiency (EE) and drug loading (DL) of paclitaxel-loaded polybutylcyanoacrylate nanoparticles (PTX-PBCA-NPs) and optimize the preparation of PTX-PBCA-NPs.

METHODSWith DL and EE as the major indexes, the qualities of PTX-PBCA-NPs produced by the interfacial polymerization and emulsion polymerization method were compared. The optimized prescription was obtained by orthogonal design.

RESULTSThe ranges of EE of PTX-PBCA-NPs with the two methods were both 94.39%-99.23%. The highest DL with interfacial polymerization was (1.07-/+0.03)%, as compared to (0.86-/+0.01)% with emulsion polymerization. The optimized preparation conditions resulted in the mean size of PTX-PBCA-NPs of 235.6 nm, DL of 0.80%, and EE of 95.71%.

CONCLUSIONThe EE of PTX-PBCA-NPs prepared by the above two methods is consistent with the requirement of the Pharmacopoeia of China, and PTX-PBCA-NPs containing higher DL can be obtained via interfacial polymerization.

OBJECTIVETo investigate the expression of survivin and COX-2 in giant cell tumor of bone (GCT) and explore the prognostic factors for GCT.

METHODSThe expressions of survivin and COX-2 in 39 GCT tissues of three Jaffe grades and 4 normal bone tissues were detected by immunohistochemical staining, and the data were analyzed in relation to the clinicopathological features of the patients.

RESULTSThe expressions of survivin and COX-2 were significantly higher in the GCT tissues than in normal bone tissues (P<0.01). A positive correlation was found between survivin and COX-2 expressions and the pathological grade (P<0.01), but their expressions were not correlated to the patients' gender, age or surgical approaches (P>0.05). An obviously lowered recurrence rate was observed in patients with resection of the bone segment compromised by the tumor and subsequent bone grafting. Survivin and COX-2 were not independent risk factors of the prognosis of GCT.

CONCLUSIONSurvivin and COX-2 expressions may participate in the pathogenesis and development of GCT, but is not indicative of the prognosis.

OBJECTIVETo observe the clinical effects of the no-flip procedure with the Chinese Shang Ring when circumcising adult males with redundant prepuce or phimosis, and to discuss its advantages and disadvantages.

METHODSUsing the no-flip Shang Ring technique, we performed circumcision for 167 adult males aged 18 -72 (mean 27.8) years with redundant prepuce or phimosis, and analyzed the clinical data, including the operation time, postoperative complications, ring-removal time, and postoperative appearance of the penis.

RESULTSComplete follow-up data of 94 cases (56.29%) were obtained. The mean operation time was (5.03 +/- 0.71) minutes and the average ring-removal time was (18.83 +/- 6.70) days. The primary postoperative complications were edema (35 cases [37.23%] at 2 weeks and 9 cases [9.57%] at 4 weeks), including 2 severe cases (2.13%), and infection (3 cases [3.19%]). The pain scores were 2.01 +/- 2.46 during the procedure and 4.52 +/- 2.53 at 24 hours postoperatively. Slipping of the outer ring occurred in 1 case, and delayed removal of the ring in 30 cases (31.91%).

CONCLUSIONAdult male circumcision with the no-flip Shang Ring technique is recommended for its short operation time, simple procedure, fewer postoperative complications, less pain, and better incision appearance.

OBJECTIVETo observe the anti-tumor effect of combination TNF-related apoptosis-inducing ligand (TRAIL) with aspirin on liver cancer cell line, SMMC-7721.

METHODSThe survival fraction of SMMC-7721 cells was measured by MTT assay, apoptosis rate and cell cycle was determined by flow cytometry, and the expression of apoptosis-related gene was identified by western blot.

RESULTSThe survival fraction of SMMC-7721 cells treated with 300 ng/ml TRAIL, 3 mmol/L or 10 mmol/L aspirin alone was 82.76%, 81.34% and 71.29% respectively, and the survival fractions of SMMC-7721 cells treated with TRAIL and 3 mmol/L or 10 mmol/L aspirin were 43.54% and 37.8% respectively. The apoptosis rates of SMMC-7721 cells induced by TRAIL and 3 mmol/L or 10 mmol/L aspirin were higher than that induced by TRAIL or aspirin alone (34.76% and 38.56% vs 21.25%, 1.89% and 6.08%), and G0/G1 arrest was observed under TRAIL and aspirin. The expression of Bcl-2 in SMMC-7721 cells treated by 3 mmol/L or 10 mmol/L aspirin decreased markedly, but no effect on Bax.

CONCLUSIONThe cooperative anti-tumor effect of aspirin and TRAIL may be related to the inhibition of the expression of Bcl-2 by aspirin

OBJECTIVETo analyze the characteristics of atrial tachycardia originating from the atrioventricular cingulum.

METHODThe electrophysiological mechanism, ablation site graph and nerve distribution of 16 cases of atrial tachycardia originating from the atrioventricular cingulum or adjacent atrial muscle which were proved by electrophysiological monitoring and radiofrequency ablation.

RESULTSAtrial tachycardia from peri-cingulum represented 23.2% of atrial tachycardia treated by radiofrequency ablation during the same period. The ratio of left to right atrioventricular cingulum was 3:16. There was no difference of the surface ECG characteristics and electrophysiological mechanism between the atrial tachycardia originating from atrioventricular cingulum and that from other positions. Both A and V components were recorded at all the successful ablation sites. The ratio of amplitude of A to V was between 2:3 and 6:1. Atrial potential in the target site was 20-46 (38.6 +/- 6.7) ms earlier than P'wave in surface ECG. The success rate of ablation was 87.5% and the recurrent rate 7.1%.

CONCLUSIONSPeri-cingulum atrial tachycardia accounts for a certain proportion in all atrial tachycardia. The exciting sites originating from right cingulum are more common than those from left cingulum. Its electrophysiological mechanism has no difference from other positions. Cingulum mapping and ablation have important practical meanings.

Two specific antigenic determinant from dengue virus type 1 and dengue virus type 2 were confirmed using Western blot, while the others epitopes shown no antigenic reaction property. Conclusion Two specific antigenic determinant were confirmed, under Western blot.

OBJECTIVETo analyze the reason of biochemical suboptimal response in CHB patients with complete virological response after more than 2 years standard treatment with Nucleos(t)-ide analogs (NUCs).To evaluate the efficacy and safety profiles of bicyclol tablets plus on the basis of the original treatment and lifestyle intervention. in CHB patients complicated with fatty liver.

METHODSIn 40 patients with chronic hepatitis B meeting the inclusion criteria,the liver biopsy was conducted.And patients complicated with fatty liver were treated with bicyclol tablets (25 mg, t.i.d) additional consecutive 48 weeks. The changes of serum biochemistry indexes and liver fibrosis index were observed before and after treatment.

RESULTSAmong 40 patients, 27 were complicated with fatty liver(69.23%), fatty degree in liver cell and liver inflammatory were closely related to the advanced fibrosis (x² =4.746, P=0.029; x² =5.072, P=0.024). The expression of HBsAg in serum and liver tissue showed no correlation with the advanced fibrosis (x² = 0.273, P=0.601; x² = 0.020, P =0.887) After bicyclol tablets treatment, serum biochemistry of patients complicated with fatty liver significantly decreased (F=58.045, P =0.000), plasma GST-PX significantly increased (t=15.109, P =0.000), plasma MDA significantly decreased (t=-10.786, P=0.000); LSM significantly decreased (t=2.255, P=0.036; t =5.376, P =0.002).

CONCLUSIONFor the antiviral purpose of guide treatment, CHB patients treated with Nucleos(t)-ide analogs (NUCs) with biochemical suboptimal response, other risk factors should be considered as early as possible. Bicyclol plus lifestyle intervention was effective for chronic hepatitis B combined fatty liver patients with poor biochemical responses.
