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 constract and evaluate the cationic anticancer peptide Temporin-1CEa liposomes and evaluate anti-breast cancer activity in vitro.Methods The polyethylene glycol (PEG)-modified liposomes containing Temporin-1CEa, one recently discovered cationic anticancer peptide ( CAP) , were constructed by using reverse-phase evaporation method.The encapsulation efficiency, particle size and Zeta potential of the Temporin-1CEa-containing liposomes (Temporin-1CEa-LIP) were characterized.In addition, that had the furhter evaluated of the stability and specific toxicity against human breast cancer MCF-7 cells in vitro.Results The data suggested that the PEG-modified liposomes served a promising drug delivery system for CAPs, those indicated by the encapsulation efficiency was (55.57 ±1.56)%, the particle size was (105.3 ±1.37) nm and the Zeta potential was ( -16.17 ±0.964) mV.Moreover, the in vitro test also indicated that Temporin-1CEa-LIP exerted good stability in serum, and it could be efficiently uptaken by MCF-7 cells.Most importantly, after 24h exposure, Temporin-1CEa-LIP showed toxicity against MCF-7 cells, as potent as Temporin-1CEa. Conclusion The results demonstrates that the PEG-modified liposome is a good drug-delivery system and Temporin-1CEa-LIP could serve as potential anti-tumor candidate for cancer therapy.

Objective To study the receptors for the axon guidance factor Netrin-4 and whether the known Netrin-1 receptors, DCC and UNC5H1, are coreceptors for Netrin-4. Methods The receptor for Netrin-4 was detected by affinitycytochemistry and in situ staining with the alkaline phosphatase (AP) tagged Netrin-4 fusion protein. The dynamic character of the binding between Netrin-4 and its receptor was evaluated through ligand-receptor binding assay and competitive binding assay. Results In situ staining of AP4-Netrin-4 protein bound to COS7 cells transiently transfected with eukaryotic expression coding DCC and UNC5H1 showed that the Netrin-4 could bind to the transfected cells. Competitive binding assays showed that Netrin-1 could compete with Netrin-4 for the same receptors. Conclusion DCC and UNC5H1 are coreceptors for Netrin-4. However, because the binding affinity of Netrin-4 with its receptor was lower than that of Netrin-1,it could be inferred that there should exist unique receptor(s) for Netrin-4 other than DCC and UNC5H1.

OBJECTIVETo investigate the distribution of estrogen receptor beta (ERbeta) gene polymorphisms between the Uygurs and the Hans in Urumqi and the association of the polymorphisms with intrahepatic cholestasis of pregnancy (ICP).

METHODSICP cases and controls from a hospital were recruited from April 2008 to April 2011,and a total of 105 ICP patients in Uygurs case group and 105 ICP patients in Hans case group were randomly selected, meanwhile, 105 Uygurs and 105 Hans healthy pregnant women were recruited as control group. The distribution of Rsa I and Alu I of ERbeta gene polymorphism were analyzed by PCR amplification and restriction and other molecular biology approaches. Data were analyzed by chi2 and Fisher exact probability.

RESULTSIn Uygurs case group, the genotype frequencies of rr, Rr,RR,aa, Aa and AA were 39.0% (41 cases), 50.5% (53 cases), 10.5% (11 cases), 62.7% (66 cases), 30.5% (32 cases), 6.8% (7 cases). In Uygurs control group, the frequencies were 21.0% (22 cases), 56.2% (59 cases), 22.8% (24 cases), 80.0% (84 cases), 18.1% (19 cases), 1.9% (2 cases). In Hans case group, the genotype frequencies of rr, Rr, RR, aa, Aa and AA were 40. 0% (42 cases), 45.7% (48 cases), 14.3% (15 cases), 66.7% (70 cases), 29.5% (31 cases), 3.8% (4 cases). In Hans control group,the frequencies were 29.5% (31 cases), 57.2% (60 cases), 13.3% (14 cases), 74.2% (78 cases), 23.8% (25 cases), 2.0% (2 cases). The genotype frequencies were not statistically significant between the two case groups and between the two control groups (all P values > 0.05), and between two Hans groups (P > 0.05). The frequencies of RRaa in the Uygur case group was lower(4. 76% ,5 cases)than control group (13.33%, 14 cases) (P <0.05), while the frequencies of rrAa in the Uygur case group was significantly higher (14. 29% ,15 cases)than control group (2.86%, 3 cases) (all P values < 0.05).

CONCLUSIONThe distribution of ERbeta gene polymorphism is of no significant difference between the Uygurs and Hans, ERbeta gene polymorphism may correlate with pathogenesis of ICP in the Uygurs other than in the Hans, and rrAa might be risk factor for ICP in the Uygurs.

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.

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.

Objective To observe the changes of nerve fibers of internal capsule and motor function in patients with thalamic hematoma treated by minimally invasive procedures using diffusion tensor imaging (DTI).Methods Twenty-two patients with thalamic hematoma were randomized into minimally invasive treatment group (MI group) and medication treatment group (MT group).The patients in MT group were given conventional medical treatment,and those in MI group were performed intracranial hematoma elimination by the minimally invasive procedures within 24 h of admission and medical treatment was also given.The patients in both MI group and MT group underwent a whole-brain DTI on admission and 2 weeks after the admission.The integrity of corticospinal tract (CST) in the internal capsule ipsilateral to the hematoma side and the contralateral side and their fractional anisotropy (FA) values were determined.The modified National Institutes of Health Stroke Scale (mNIHSS) were performed on admission,2 weeks and 1 month after onset of initial hemorrhage.Results DTI showed that fibers in the internal capsule ipsilateral to the hematoma either decreased in number or interrupted because of hematoma-induced damages in both groups,and the CST FA values on admission were significantly lower (0.432±0.022 and 0.410±0.028 for MI and MT groups,respectively) than the control values.The number of fibers and the FA values of CST in the internal capsule 2 weeks after the hematoma being evacuated were increased significantly as compared with those on admission.As FA values of CST in internal capsule increased,the mNIHSS scores decreased after the surgery and the motor function improved gradually.Conclusion Minimally invasive procedures for thalamic hematoma evacuation can effectively reduce the degree of injury to the motor function,and DTI can observe the changes of CST after the surgery directly.

OBJECTIVETo explore the feasibility and safety of conditioning regimen containing fludarabine (Flud) for haploidentical hematopoietic stem cell transplantation (HSCT).

METHODSPreparative regimen containing Flud 40 mgxm(-2)xd(-1) on day -7 to -3 in place of cyclophosphamide (CTX) for haploidentical HSCT was given to 35 patients with hematologic malignancies (4 standard risk, 16 high risk, 15 relapse with no remission). All donors received rhG-CSF followed by HSC harvest. One patient received peripheral blood HSCT (PBSCT), one bone marrow transplantation (BMT), and the others BM combination with PBSCT. The regimen-associated side effect, engraftment, incidence of graft-versus-host disease (GVHD) and disease-free survival (DFS) probabilities were observed.

RESULTSAll patients achieved sustained, full donor-type engraftment. Thirty-four patients obtained primary durable engraftment, and 1 who rejected graft from his mother obtained successful durable engraftment after the second graft from his father. The cumulative incidence of grade III-IV acute GVHD and chronic GVHD was 12.1% and 31.7%, respectively. With a follow-up duration of 8-25 months, 6 patients were dead, in which 3 died of relapse, 2 of acute GVHD, 1 of fungal infection, none died of regimen-associated side effect. The other 29 patients remained alive and DFS probability was 79.7%.

CONCLUSIONFlud based conditioning regimens for haploidentical HSCT is safe and feasible, which reduces regimen-associated side effect, with no increasing the rate of relapse and infection, and decreases the incidence of aGVHD.

The purpose of this study was to compare the efficacy of CEP plus G-CSF and CVP plus G-CSF regimens in the mobilization and collection of peripheral blood hematopoietic stem cells (PBHSC), and in the hematopoietic recovery. 57 patients with non-Hodgkin's lymphoma (NHL) underwent autologous PBHSC transplantation were analyzed retrospectively. The PBHSC were mobilized and collected by using CEP plus G-CSF and CVP plus G-CSF respectively, and were retransfused into these NHL patients after preconditioning, then the mobilization efficacy, adverse reactions and hematopoietic recovery were analyzed. The results showed that the WBC count decreased to ≤ 1.0 × 10(9)/L, platelet amount dropped to ≤ 40 × 10(9)/L during peripheral blood stem cell mobilization of all patients, which indicated successful collection of PBHSC. The mean value of (4.38 ± 3.40) × 10(8)/kg mononuclear cells (MNC) containing (2.79 ± 2.53) × 10(6)/kg CD34(+) cells were collected in CEP plus G-CSF group, while the mean value of (3.31 ± 1.23) × 10(8)/kg MNC containing (2.02 ± 0.87) × 10(6)/kg CD34(+) cells were collected in CVP plus G-CSF group. The efficacy of mobilization in CEP plus G-CSF group was significantly higher than that in CVP plus G-CSF group (p < 0.05). After preconditioning, bone marrow was suppressed in all patients. The average time of WBC count recovery to ≥ 1.0 × 10(9)/L was 11.4 days in CEP plus G-CSF group and 12.3 days in CVP plus G-CSF group; the average time of platelet amount recovery to ≥ 50 × 10(9)/L was 18.6 days in CEP plus G-CSF group and 19.3 days in CVP plus G-CSF group. The statistical analysis showed no significant difference in the average time of hematopoietic recovery between 2 groups. It is concluded that autologous PBHSC transplantation shows significant effect for treatment of patients with NHL. Either modified CEP or CVP plus G-CSF regimen is safe and effective in PBHSC mobilization. The CEP plus G-CSF regimen is better than CVP plus G-CSF regimen.
