OBJECTIVE: To explore the acupoint selection rules of acupuncture for Alzheimer's disease (AD) in modern clinical practice by complex network technology. METHODS: The relevant articles of clinical trials were retrieved from CNKI published before December 2017. Using Microsoft Excel 2010, the database was established. Using Gephi 0.8.2 software, the complex network mode was built and its topological structure was analyzed. RESULTS: Finally, 81 articles were eligible and 114 acupoint prescriptions were extracted. The constructed complex network of acupoint prescriptions for AD was characteristics as small world effect and scale-free property, the crucial acupoints included Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Yintang (GV 29), Shenmen (HT 7), Shenting (GV 24), Zusanli (ST 36), Fenglong (ST 40) and Taichong (LR 3). In acupoint combination, Baihui (GV 20), Neiguan (PC 6), Shenmen (HT 7) and Sanyinjiao (SP 6) were the most common, and the combination of the distal and nearby points was predominant. Using k-core for acupoint optimization, 29 core acupoints were screened and they were mostly located on the governor vessel and the head and neck, with the highest use frequency. 82.76% of acupoints were specific acupoints and the influential points were dominant. Using community structure partition, these acupoints were classified into two groups, i.e. deficiency syndrome and excess syndrome. CONCLUSION The selection of local acupoints is the first choice in acupuncture treatment for AD. The combination of distal and nearby points is the most common and the special points are the core. In clinical practice, the great consideration is provided on mind regulation, integration of disease and symptoms, the mutual treatment of the primary and the secondary as well as the deficiency and the excess.

AIM To investigate the effects of drying temperature,growing area and plucking time on hederacoside C,α-hederin from leaves of Hedera helix L..METHODS Three batches of H.helix leaves plucked in different time from two growing areas were dried in a vacuum oven to the constant weight at 60 ℃,70 ℃,80 ℃,90 ℃ and 105 ℃,respectively.Two saponins in the processed leaves were determined by HPLC.The powders of the processed H.helix leaves of different batches were mixed with proper ratios,which were determined by least squares optimization method with constraints.RESULTS The content of hederacoside C in the processed H.helix leaves of the three batches increased while that of α-hederin decreased with increasing temperature.The relative error between measured value and desired contents of hederacoside C and α-hederin in the mixed H.helix leaves was less than 5.5％.CONCLUSION The effects of three factors on the content of two saponins in the H.helix leaves are in the order of drying temperature,growing area and plucking time.Mixing processed H.helix leaves of different quality statues reasonably can control the contents of two saponins in a certain range.

OBJECTIVE: To study DNA quantification and STR typing of samples pre-treated with pyramidon. METHODS: The blood samples of ten unrelated individuals were anticoagulated in EDTA. The blood stains were made on the filter paper. The experimental groups were divided into six groups in accordance with the storage time, 30 min, 1 h, 3 h, 6 h, 12 h and 24h after pre-treated with pyramidon. DNA was extracted by three methods: magnetic bead-based extraction, QIAcube DNA purification method and Chelex-100 method. The quantification of DNA was made by fluorescent quantitative PCR. STR typing was detected by PCR-STR fluorescent technology. RESULTS: In the same DNA extraction method, the sample DNA decreased gradually with times after pre-treatment with pyramidon. In the same storage time, the DNA quantification in different extraction methods had significant differences. Sixteen loci DNA typing were detected in 90.56% of samples. CONCLUSION Pyramidon pre-treatment could cause DNA degradation, but effective STR typing can be achieved within 24 h. The magnetic bead-based extraction is the best method for STR profiling and DNA extraction.

Objective To study the epidemiological characteristics on the clustering nature of pandemic (H1N1) 2009 in China.Methods Time and place distribution of pandemic (H1N1) 2009on the nature of clustering through data from Public Health Emergency Management Information System were described.Results As of August 10,2010,2773 pandemic (H1N1) 2009 clusters,a total of 77363 cases (including 20 deaths) were reported in the mainland of China.The most reported number of clusters was from schools and kindergartens with the total number of 2498 (accounted for 90.08％ of the total number).Middle schools appeared the have the most clusters (1223,accounting for 48.96％ ).The number of clusters reported in the southern provinces (cities) accounted for 77.03％ of the total,and was more than that in the northern provinces (cities).Two reported peaks in the southern provinces (cities) were in June and November,2009,respectively.There was only one reported peakin the northern provinces in September,2009.Conclusion Time and place distribution characteristics on the clusters of pandemic (H1N1) 2009 were similar to the seasonal influenza,but the beginning of winter peak was much earlier and intensity of reporting was much higher on the clusters of pandemic (H1N1 ) 2009 than that of seasonal influenza.

OBJECTIVE: To explore the feasibility and to sum up the experience of breast intraductal neoplasm resection under breast fiberoptic ductoscopy (FDS). METHODS: FDS was performed on 548 patients with nipple discharge from Sep.2004 to Nov.2006. The clinical data of breast intraductal neoplasm found by FDS in patients who underwent tumor resection were analyzed, and the breast intraductal neoplasm image characteristics, diagnosis, operative type and postoperative pathological results were analyzed. RESULTS: Of the 548 patients with nipple discharge, intraductal neoplasm was found in 187 cases (34.1%), intraductal papilloma in 159 cases (29.0%), intraductal papillomatosis in 12 cases (2.2%), and breast carcinoma in 16 cases (2.9%). One hundred thirty-five patients were operated on in our hospital, of whom 91 were performed tumor resection or segmentectomy under the localization by FDS, and the other 44 were performed segmentectomy after breast duct infusion of methylene blue. The diagnostic rate under FDS in the FDS group (97.8%) was higher than that in the breast duct infusion methylene group (86.4%) (chi2=6.96, P=0.008). CONCLUSION FDS is not only an accurate diagnosis for breast intraductal lesion, but also an assistance to localize the breast intraductal neoplasm and to remove them in the operation.

Objective To investigate the effects of telmisartan on endoplasm retiedum (ER) stress signal pathways and eardiomyocyte apoptosis in abdominal aortic banded rats.Methods Male SD rats were randomly divided into sham-operated group,abdominal aortic banding group(AAB)and AAB+telmisartan (5 mg·kg-1·d-1 per gavage,beginning at l week before AAB for 8 weeks,n=10 each).Ten weeks post AAB,hemodynamie measurements were performed,whole heart and left ventricular weights were obtained. Cardiomyocyte apoptosis was measured by TUNEL method.Myocardial GRP78 and CHOP protein expresssions were detected by Western blot and immunohistochemistry.Results The ratio of left ventricular weight to body weisht,the ratio of heart weight to body weisht,left ventrieular end diastolic pressure and the apoptosis index were significantly increased while left ventfieular end systolic pressure and±dp/dtmax were significantly decreased in AAB group than those in sham-operated group (all P<0.01),these changes could be significantly attenuated by telmisartan (all P<0.01).Moreover,myocardial GRP78 and CHOP expressions were significantly upregulated in AAB group than those in sham-operated group and telmisartan could significantly downregulate the increased GRfp78,CHOP expressions (all P<0.01).Conclusions Increased ER stress might be responsible for enhanced eardiomyocyte apoptosis in AAB rats.Telmisartan effectively attenuated the cardiomyocyte apoptosis and cardiac hypertrophy in AAB rats possibly through reducing ER stress.

OBJECTIVETo report on a series of patients with congenital anosmia, and to discuss its classification and clinical characteristics.

METHODSEight patients with congenital anosmia were reviewed retrospectively. Four of eight cases were congenital anosmia with other abnormalities, including three cases with Kallmann's syndrome, one with hypoplasia of nasal cavity and nasal sinus. Four cases were isolated congenital anosmia. A thorough medical and chemosensory history, physical examination, nasal endoscopy, T&T olfactory testing, olfactory event-related potentials and sinonasal computed tomography scan were performed in all patients. Magnetic resonance image of olfactory pathway was available in seven cases, and olfactory biopsies were done in two cases.

RESULTSAll patients reported had never been able to smell anything. ENT physical examination and nasal endoscopy were normal, except one case with hypoplasia of nasal cavity. Subjective olfactory test indicated all of them were anosmia. No olfactory event-related potentials to maximum stimulus were obtained. Magnetic resonance imaging revealed the absence of olfactory bulbs and tracts in six cases, hypoplasia of bilateral olfactory bulbs and tracts in one case. Computed tomography scan indicated normal except hypoplasia of nasal cavity and sinus in one case. Three cases with Kallmann syndrome showed poor development of both primary and secondary sexual characteristics and had decreased serum luteinizing hormone, follicle-stimulating hormone, testosterone and estradiol.

CONCLUSIONSDiagnosis of congenital anosmia is established on chief complain, physical examination, nasal endoscopy, olfactory testing and olfactory imaging. Magnetic resonance imaging of olfactory pathway is indispensable.

OBJECTIVETo observe the relationship between abdominal obesity and left ventricular weight/function.

METHODSA total of 495 patients [265 males, mean age (55 +/- 12) years] with hypertension (139), diabetes (65), metabolic syndrome (285), diabetes complicated with hypertension (11) were enrolled in this study. Visceral adipose area (VA), the subcutaneous adipose (SA), the total abdominal adipose (TA) were measured by computerized tomography (CT) and left ventricular weight and function were obtained by echocardiography. Patients were divided into three groups according to the VA (I. VA<75 cm(2), n=173, II. VA>75 and < 110 cm(2), n=153, III. VA >or= 110 cm(2), n=169).

RESULTSLeft ventricular mass (LVM) and LVM index (LVMI) increased and LVEF and E/A decreased in proportion to increasing VA. Left ventricular hypertrophy (LVH) rate was significantly higher in group II and III compared to group I and LVEF was significantly reduced in group III compared to group I and II. There are significant correlation between LVMI and VA, SA, TA as well as between LVEF and VA after adjusting gender, age and blood pressure. Logistic regression analysis showed that VA is an independent predictor for LVH.

CONCLUSIONThe abdominal adipose accumulation is closely related to the left ventricular weight and function.
