OBJECTIVETo investigate and explain the composing mechanism by observing enhancement property of disassembled compositions of Yiqi Huoxue decoction (YQHXD) on platelet aggregation of health adults.

METHODVenous whole blood was obtained from healthy human subjects and anti-coagulated, and then centrifuged to produce platelet-rich plasma (PRP) and platelet-poor plasma (PPP). Disassembled compositions of YQHXD and sodium chloride were placed in different translucent tubes containing PRP and PPP, calculated the maximum percents of platelet aggregation stimulated by platelet agonists: adenosine diphosphate (ADP), platelet activating factor (PAF) and arachidonic acid (AA).

RESULTThe maximum percents of platelet aggregation induced by ADP and PAF were largely improved by YQHXD, both astragalus membranaceus and Angelica Scinesis played the most important roles in the decoction, the herbs of Yiqi and Huoxue must work together to enhance platelet aggregation.

CONCLUSIONIn vitro study, YQHXD can markedly improve platelet aggregation of health adults, but the exact mechanism should be proved by further experiments.

Objective To explore the application effect of nosting barrier film in the skin nursing of laryngeal carcinoma patients with trachea cannula after surgery.MethodsTotally 90 cases of laryngeal cancer patients after radiotherapy with tracheal cannula,were randomly divided into three groups,with 28 cases in the control group,33 cases in the dressing group,and 29 cases in the skin protective film group. Patients in the control group were treated with basic nursing method including using saline to clean plastic casing,cleaning and disinfecting skin,using sterile gauze to cover the field of radiation skin and plaster fixation;dressing group adopted Comfeel hydrocolloid dressings on the basis of basic nursing method;skin protective film group adopted Genetime spray skin protective film to protect skin of radiation field on the basis of basic nursing. After radiotherapy,the incidence of skin injury,severity of skin injury,patient comfort,and the time and times of changing skin dressing everyday were observed and compared among three groups.Results The incidence of radiation skin injury in the skin protective film group (6.89%) and dressing group (15.15%),were all lower than the control group (50%) (χ2=16.75,P<0.05);the times of changing skin dressing everyday in the skin protective film group (4.28±0.53) times/d and the dressing group (4.52±0.76) times/d,were lower than the control group (6.04±1.35) times/d (Hc=32.65,P<0.05);patient comfort in the skin protective film group and the dressing group was superior to the control group (Hc=22.42,P<0.05);the time of changing skin dressing in the skin protective film group (10.40±1.35) min,was less than the dressing group (14.09±1.27) and the control group (12.35±1.28) min (F=85.87,P<0.05).Conclusions The skin protective film can effectively reduce the incidence of skin injury in patients with laryngeal cancer and radiotherapy,improve patient comfort,reduce the labor time of nurses,and improve the quality of care and efficiency.

OBJECTIVE: This study was performed to evaluate the results of conization by loop electrosurgical excision procedure (LEEP) and cold coagulation as a definitive treatment in the patients with FIGO stage Ia1 squamous cell carcinoma of the cervix. METHODS: One hundred eighty-seven patients were diagnosed as stage Ia1 cervical squamous cell carcinomas from 1995 to 2004 by conization with LEEP and cold coagulation. Fifty-nine patients who wanted to preserve fertility and/or refused further surgical treatment were followed-up without further treatment. Eleven patients of the 59 had involved ectocervical resection margins. All patients were followed-up with cervicovaginal smear and colposcopic examination at a regular interval. Disease recurrence was defined as a histologic diagnosis of dysplasia or more. RESULTS: The median follow-up period was 69.0 months (range 8 to 103). All 59 patients had no lymphvascular space invasion (LVSI). In four patients, the ectocervical margins were involved by dysplasia, in seven patients, by carcinoma in-situ. There were no specific differences in ages, depth of stromal invasion and HPV status between the groups with and without involved margins. All 59 patients did not recur during follow-up period. CONCLUSION: Conization with LEEP and cold coagulation was feasible and could be used as a definitive therapy for the patients with stage Ia1 cervical squamous cell carcinoma. This study suggests that conization might play a role in a patient with positive margins (dysplasia or CIS) when LVSI is not demonstrated.

Objective To investigate the iodine nourishment in women of child-beating age in high risk region of iodine deficiency disorders (IDD) in Qinghai Province. Methods According to The Notice to Launch a Reinforced Survey on IDD in High Risk Region issued by The Ministry of Public Health, 17 counties in 6 districts were selected as investigated area in Qinghai Province in 2007, using two stage cluster sampling and combining The National IDD Preliminary Surveillance Scheme, 30 women aged from 18 to 40 years were selected in each village, 1 or 2 villages in each town, 3 to 5 towns in each county, who were divided into newly wedding, pregnant, lactation and other women of child-bearing age. Iodine concentration in urine was detected by the method of As3+-Ce4+catalytic spectrophotometry. Results One thousand six hundreds and four urine iodine samples were analyzed. The median was 93.3 μg/L,52.1%(836/1604),31.8%(510/1604) and 12.4%(199/1604) was lower than 100,50 and 20 μg/L, respectively. It was 70.5%(527/747) and 43.0%(128/298) of women in Yushu and Haixi that had urinary iodine lower than 100 μg/L, respectively, while it was 50% of women in the 6 districts, to be specific, 88.3%(91/103) in Nangqian, 83.8% (62/74) in Zaduo and 70.7%(118/167) in Zhiduo Counties respectively. The median of urinary iodine in women who were not lactating and not pregnant was only 88.6 μg/L, of whom 53.9% (763/1415) lower than 100 μg/L. Conclusions The women of reproductive age in high risk region of IDD are deficient of iodine in Qinghai Province.

Palatal radicular groove leads to severe endo-periodontal lesion in lateral incisors. The groove occurs on the labial and lingual root surfaces, while the localized periodontal pocket develops along the lingual groove length. The complicated root canal system, extensively destroyed bone lamella, and persistent fistula pose a challenge for root canal therapy, tooth retention, and thorough infection control inside and outside of the root canal. Combining microscopic root canal therapy with intentional replantation and nano-biomaterial application facilitates infection control, tooth retention, and formation of newly periodontal attachment.

OBJECTIVETo investigate the telomerase activity in mesenchymal stem cells (hMSCs) from human bone marrow after their in vitro committed differentiation into adipocytes and cryopreservation.

METHODShMSCs were isolated from human bone marrow. The isolated hMSCs were induced to differentiate into adipocytes in vitro or cryopreserved. TRAP assay (telomerase repeat amplification protocol assay) was employed to detect telomerase activity in those hMSCs.

RESULTSTelomerase activity (RTA) in hMSCs (n=19) was (1.46 +/-0.67)%, while that in hMSCs-derived adipocytes (n=3) was (11.80 +/-2.52)% (P<0.001). RTA of hMSCs-passage 1.3 (n=10) was (1.46+/-0.83)%, and that of hMSCs-passage 4-7(n=9) was (1.46 +/-0.47)% (P=0.99). Cryopreservation did not affect the telomerase activity in hMSCs, RTA of fresh hMSCs (n=13) was (1.41 +/-0.44)%, RTA of frozen hMSCs (n=6) was (1.57 +/-1.07)% (P=0.64).

CONCLUSIONhMSCs are telomerase-negative, but telomerase activity in hMSCs-derived adipocytes is upregulated.
