The present study was aimed to investigate the effect of electroacupuncture (EA) on learning-memory of rats with low estrogen-induced cognitive impairment and the possible mechanism. The rat model was established by ovariectomy, which resulted in low estrogen-induced cognitive impairment. EA was applied continuously for 3 months 2 weeks after ovariectomy. Morris water maze was used to test the ability of spatial learning and memory. Enzyme-linked immunosorbent assay (ELISA) and real-time quantitative RT-PCR were used to detect the concentration of serum estradiol (E2) and relative expression of choline acetyltransferase (ChAT) mRNA in hippocampus, respectively. The result showed that, compared with the sham group, the ovariectomy model group exhibited longer escape latency, reduced number of platform-crossing, lower concentration of serum E2, and decreased expression of ChAT mRNA in hippocampus. EA shortened the escape latency and increased the number of platform-crossing in the ovariectomy model group. Moreover, the concentration of serum E2 and the hippocampal expression of ChAT mRNA in the ovariectomy model group were significantly elevated by EA treatment. These results suggest EA is capable of improving learning and memory in ovariectomized rats, and the mechanism involves the up-regulation of the expression of ChAT mRNA in hippocampus induced by the increase of the serum concentration of estrogen.

The essence of endogenous turbidity in Chinese medicine (CM) is different from cream, fat, phlegm, retention, damp, toxicity, and stasis. Along with the development of modern scientific technologies and biology, researches on the essence of endogenous turbidity should keep pace with the time. Its material bases should be defined and new connotation endowed at the microscopic level. The essence of turbidity lies in abnormal functions of zang-fu organs. Sugar, fat, protein, and other nutrient substances cannot be properly decomposed, but into semi-finished products or intermediate metabolites. They are inactive and cannot participate in normal material syntheses and decomposition. They cannot be transformed to energy metabolism, but also cannot be synthesized as executive functioning of active proteins. If they cannot be degraded by autophagy-lysosome or ubiquitin-prosome into glucose, fatty acids, amino acids, and other basic nutrients to be used again, they will accumulate inside the human body and become endogenous turbidity. Therefore, endogenous turbidity is different from final metabolites such as urea, carbon dioxide, etc., which can transform vital qi. How to improve the function of zang-fu organs, enhance its degradation by autophagy-lysosome or ubiquitin-prosome is of great significance in normal operating of zang-fu organs and preventing the emergence and progress of related diseases.

OBJECTIVETo assess the condition of myocardial injury after cardiopulmonary bypass (CPB) and the effects of breviscapine (BVC) on cardiac function in children undergoing open heart surgery.

METHODSThirty-six children (ASA II or III, aged 2-65 months) scheduled to receive ventricular septal defect repairing were randomly assigned to three groups, the control group treated with saline, and the BVC treated groups treated respectively with low dose (0.5 mg/kg) and high dose (1.0 mg/kg) BVC, 12 patients in each group. Saline or BVC (in volume of 15 mL) was administered intravenously after induction of anesthesia with micro-pump within 30 min. Blood levels of troponin I (cTn-I ) and malondialdehyde (MDA) were measured at different time points: pre-operation (T0), during aortic unclamping (T1), and 30 min, 1 h, 6 h, 24 h after aortic unclamping (T2, T3, T4, T5). And the time of operation, CPB, aortic unclamping, and the condition of drainage in 24 h after operation as well as the dosages of narcotics (midazolam, propofol and fentanyl) used were recorded.

RESULTSNo significant difference among groups was found in terms of sex ratio, age, body weight, time of aortic unclamping, CPB and operation, as well as the dosages of narcotics used and the volume of post-operation drainage. Compared with baseline (T0), levels of cTn-I at T1, T4 and T5 increased significantly in all three groups (P<0.01), with the peak revealed at T4; cTn-I in the control group were higher than those in the low dose BVC treated group at T1 and T4 (P<0.01), and those in the high dose BVC group at T1, T4, and T5, while it was insignificantly different between the two BVC treated groups. Level of plasmal MDA began to rise in all groups at T1 with the peak revealed at T2, it lowered after then, and reached the baseline at T5; comparison between groups showed that it was lower in the BVC treated groups than in the control group at T1-T4.

CONCLUSIONSDifferent degree of cardiac injury always happens after open heart surgery and CPB, showing high level of cTn- I within 24 h with the peak revealed at 6 h after aortic unclamping. Intravenous perfusion BVC before CPB at the dose of 0.5 or 1 mg/kg could protect the cardiac function to some extent.

OBJECTIVETo verify the clinical efficacy of heat-sensitive moxibustion in treatment of knee osteoarthritis (KOA).

METHODSSixty cases of KOA were randomly divided into a heat-sensitive moxibustion group and a conventional moxibustion group, 30 cases in each one. Dubi (ST 35), Yanglingquan (GB 34), Zusanli (ST 36) and Heding (EX-LE 2) on the affected side were selected in two groups. In heat-sensitive moxibustion group, the techniques of circling moxibustion, sparrow-pecking moxibustion, moving moxibustion and mild moxibustion were applied. In conventional moxibustion group, the mild moxibustion was used, 2 to 3 cm far from the skin of the acupoints selected. Lysholm scale for the assessment of knee joint function was adopted to evaluate the efficacy. The scores of joint pain, morning stiffness, joint swelling and walking ability were compared before and after treatment in two groups.

RESULTSThe scores of joint pain, morning stiffness, joint swelling and walking ability after treatment were all apparently improved as compared with those before treatment in either group (all P < 0.05). The improvement in the above-mentioned indices in heat-sensitive moxibustion group was much more apparent as compared with that in conventional moxibustion group (all P < 0.01). The effective rate was 90.0% (27/30) in heat-sensitive moxibustion group and was 73.3% (22/30) in conventional moxibustion group. The effective rate in heat-sensitive moxibustion group was obviously superior to that in conventional moxibustion group (P < 0.01).

CONCLUSIONThe efficacy of heat-sensitive moxibustion is superior to that of conventional moxibustion in the treatment of KOA. This therapy can more significantly improve the symptoms and physical signs of the patients with KOA.

OBJECTIVETo establish a diagnostic model of protein fingerprint pattern in the cerebrospinal fluid (CSF) for non-small-cell lung cancer (NSCLC) patients with brain metastases.

METHODSThe CSF samples were obtained from 29 NSCLC patients with brain metastasis, 23 non-tumor patients and 10 early-stage NSCLC patients without brain metastases for analysis of the protein expression profiles using surface-enhanced laser desorption/ionization-time of flight-mass spectrometry (SELDI-TOF-MS). The data were then analyzed by Biomarker Wizard software, and the tree analysis patterns were generated using the decision-tree model in Biomarker Patterns software. The diagnostic model was tested for its clinical application.

RESULTSFive protein peaks were identified showing differential expression between patients with brain metastases and those without brain metastases. Combination of the 3 protein peaks (m/z: 8698.00, 1215.32 and 1245.70) could discriminate these two samples with a sensitivity of 100.00% (29/29) and a specificity of 100.00% (23/23). Five proteins were differentially expressed between the NSCLC patients with brain metastases and the non-tumor patients. With one protein peak (m/z: 6050.00), these two samples could be discriminated with a sensitivity of 90.00% (9/10) and a specificity of 78.26% (18/23).

CONCLUSIONThe established diagnostic model of CSF protein fingerprint pattern provides high sensitivity and specificity in the diagnosis of NSCLC with brain metastasis.

Objective To explore the correlation between TCM constitution and sleep status in escort troops. Methods Standardized TCM Constitution Questionnaire and Pittsburgh Sleep Quality Index (PSQI) were used to investigate escort troops. Factors of PSQI and constitution types were analyzed. Results The results of PSQI showed the number of escort troops who had bad sleeping (PSQI>7) was 64, which accounted for 46%of the escort troops, among which, 45 people (70.3%) were justified as biased constitution, while 19 were normal constitution (29.7%). The top three biased constitution in bad sleeping were:qi deficiency, phlegm-dampness and dampness-heat. PSQI factors such as sleep disorder, daytime dysfunction and total score had positive correlation with qi deficiency, yang deficiency, yin deficiency, dampness-heat and blood stasis, and negative correlation with normal constitution. Conclusion Sleep condition of escort troops has correlation with TCM constitution, which indicates that sleep status could be improved by regulating TCM constitution.

Objective To investigate the effect of platelet-rich plasma(PRP) combined with bone graft in the treatment of humeral condylar bone defect.Methods A total of 135 patients with humeral condylar bone defect in Ankang central hospital from January 2012 to December 2015 were divided into the PRP combined group(n =69) and the conventional group(n =66) according to the order of admission time.The patients of PRP combined group were treated with platelet-rich plasma combined with autologous bone graft,and patients of conventional group received autologous bone graft,respectively.The surgery time,hospitalization time,wound healing,fracture union and the motion of elbow joint at postoperative 1 year between two groups were compared.The Kaplan-Meier survival curve was used to reflect the bone healing in both groups,and the log-rank test was used to compare the result.Results There was no statistically significant difference in the surgery time,hospitalization time,wound healing and motion of elbow joint at postoperative 1 year between the two groups(P ＞ 0.05).But the average time of wound healing (3.8 ± 0.72) weeks and the time of bone union (18.8 ± 3.50) weeks in PRP combined group were significantly shorter than (6.4 ±0.58) weeks and (22.7 ± 1.55) weeks in the conventional group(P =0.000),the differences were significant.The KaplanMeier survival curve of the bone union in the PRP combined group was also significantly better than that in the conventional group.Conclusion PRP can promote the healing of fracture in patients with humeral condylar bone defect after autologous bone graft,which contributes to the recovery of elbow function.

OBJECTIVETo detect the female carriers from the intron and/or exon-deletion Duchenne/Becker musclular dystrophy (DMD) familial members for prenatal or preimplantation genetic diagnosis.

METHODSUsing method of PCR to five microsatellite markers (located in 5' terminus and intron 44, 45, 49, 50), analysing of the short tandem repeat sequence polymorphism with the genescan and binding with the quantitative polymerase chain reaction, we detected the DMD carriers from 1 intron and exon -deletion family and 1 intron-deletion family.

RESULTSThe STR-50 genotype of II 2 in family 5 was 245/245, so II3 is DMD gene carrier. The STR-45 genotype of II6 and II8 were del/172, III19 was del/178, so they were all DMD gene carriers.

CONCLUSIONThe STR haploid linkage analysis combined with quantitative polymerase chain reaction is accurate and efficient to detect the female carriers from the intron and/or exon-deletion DMD familial members.
