Objective To observe the clinical efficacy of XIE’s Wen Du Qu Mai (Warming the Governor Vessel to expel smog) needling method plus heat-sensitive moxibustion in treating chronic simple rhinitis due to yang deficiency. Method Eighty patients with chronic simple rhinitis due to yang deficiency were randomized into a treatment group and a control group, 40 in each group. The treatment group was intervened by acupuncture plus heat-sensitive moxibustion, while the control group was by medication. The symptom and sign score was observed before and after 1-week treatment, and the clinical efficacy was compared. Result The total effective rate was 85.0%in the treatment group versus 55.0% in the control group, and the difference was statistically significant (P<0.05). The symptom and sign scores were changed significantly after treatment in both groups (P<0.01,P<0.05). After treatment, the symptom and sign score in the treatment group was significantly different from that in the control group (P<0.05). Conclusion XIE’s Wen Du Qu Mai needling method is effective in treating chronic simple rhinitis due to yang deficiency.

Objective To evaluate the size of the liver tissue necrosis at different power and energy, to search the size of liver tissue necrosis at ideal power and energy, and to provide dependable data for semiconductor laser-therapy in malignant hepatic tumor. Methods Ten rabbits were included, and the rabbit liver tissue was fired using semiconductor laser at 1 W, 2 W, and 3 W with the energy of 200 J, 400 J, 600 J, 800 J, and 1 000 J. The diameters of the necrosis and charring in the target area were measured. Results The diameter of the liver tissue necrosis and charring was from 4.3 mm and 7.8 mm at 1 W to 10.4 mm and 21.9 mm at 2 W in 1 000 J. From 2 W to 3 W, the diameter of the liver tissue necrosis and charring remained unchanged. At the power of 2 W, the diameter of liver tissue necrosis and charring was proportional to the energy, and the areas of necrosis were correlated with that of charring. Conclusion Semiconductor laser photocoagulation is safe and feasible. This experiment supplies valuable laboratorial data for further clinical study.

Objective To evaluate the value of DSA in the diagnosis of staging moyamoya disease (MMD).Methods DSA of 31 patients with MMD were reviewed retrospectively. Results The stenosis or occlusion with different extents of the supracranial internal carotid arteries and the collateral circulations were shown in DSA of the all patients. MMD lesions of 57 cerebral hemispheres shown in the DSA of 31 patients were diagnosed by staging according to the description of Suzuki: Stage Ⅰ in 4 cerebral hemispheres; Ⅱ,10;Ⅲ17;Ⅳ12;Ⅴ6 and Ⅵ,8. Conclusions DSA could show clearly the stenotic degree, occlusive site and collateral circulation of the MMD and simultaneously with the staging of the disease; and thus guiding the choice for early surgical teatment.

Objective To explore the surgical skill, safety, and cosmetic outcomes of complete endoscopic subcutaneous mastectomy and immediate reconstruction with implants for breast cancer. Methods From August 2004 to September 2007, 31 women with breast cancer received complete endoscopic subcutaneous mastectomy and immediate reconstruction with implants in our hospital after neoadjuvant chemotherapy. The operation spaces were established by insufflating carbon dioxide after lipolysis and liposuction in the subcutaneous stratum and retromammary space. Subcutaneous mastectomy was carried out under a complete endoscope, sentinel lymph node biopsy or axillary lymph node dissection, and immediate reconstruction with implants were carried out via axillary small incision. Results The operations were completed in all of the 31 cases. Sentinel lymph node biopsy was performed on 15 cases (including supplemental axillary lymph node dissection in 8), and immediate axillary lymph node dissection was done in 16 cases. No cancer infiltration on tumor surface or into the nipple basement was observed in frozen sections during the operation. In one patient, the nipple was partly necrotic. No other complications were found in this series. Three months after the operation, cosmetic results were good in 22 cases (71.0%), average in 7 (22.6%), and poor in 2 (6.4%). The patients were followed for 3 months to 3 years (over 1 year in 15 patients), during which no one had metastasis or recurrence of the tumor. Conclusions Complete endoscopic subcutaneous mastectomy combined with immediate reconstruction with implants is less traumatic and safe with few complications and good cosmetic result. The method is a good choice for patients with early-stage breast cancer.

Objective:To reveal the action of psoriatic peripheral blood T lymphocytes on keratinocytes proliferation and the significance in the pathogenesis of psoriasis.Methods:Keratinocytes were cocultivated with psoriatic peripheral blood T lymphocytes in comparison with those cocultivated with normal T lymphocytes. Immunohistochemical technique was performed to detect the expression of Ki67, c-Myc and Bcl-xL proteins.Results:There were significant overexpression of Ki67, c-Myc and Bcl-xL proteins in keratinocytes cocultivated with psoriatic T lymphocytes compared with the uncocultivated group and normal T lymphocytes group. Expression of Ki67, c-Myc and Bcl-xL proteins in keratinocytes cocultivated with normal T lymphocytes were not significantly different from the uncocultivated group.Conclusion:Psoriatic T lymphocytes, which have specific activity, can induce keratinocytes abnormal pattern of proliferation. One of the important mechanisms might be its action on the expression of c-Myc and Bcl-xL proteins.

The age of 18 is an important criterion in judicial trial, immigrant and competitive sports. Consequentially, the estimation of age 18 is a key issue in forensic practice and research. The extremitas sternalis claviculae, iliac crest, third molar, and the proximal limb of the limb bone were usually used as indictors of age 18. The results of the previous studies demonstrated that those indictors could be beneficial to the estimation of age 18. The X-ray, CT, ultrasound and MRI of different indictors were widely utilized for the estimation of age 18, particularly the thin-layer CT. But due to the non-radiation, MRI will be a trend for forensic age estimation in the future. Whilst in the previous studies, the descriptive analysis was applied for the estimation of age 18, but due to the low statistic efficiency, it is unsuitable for forensic age estimation, and the future studies should pay attention to the high efficiency statistical methods, for instance, the ROC curve or the data mining.

Objective:To explore the proliferation inhibition and radiosensitization of Biyanqing granule on nasopharyngeal carci -noma cell line CNE-2 in vitro.Methods:CNE-2 cells were cultured in vitro.The inhibition of Biyanqing granule on the proliferation of CNE-2 cell was evaluated by MTT assay .Radiosensitization was explored by clone formation assay , and cell cycle and apopotosis were observed by flow cytometry ( FCM) .Results:Biyanqing granule could inhibit the proliferation of CNE-2 in a time-and dose-dependent manner.The IC50 in 24, 48 and 72 h was 70.79, 60.13 and 51.63 mg· ml-1(calculated according to the weight of all medicinal ma-terial), respectively.The colony formation assay showed that Biyanqing granule combined with radiation could significantly reduce the colony formation of CNE-2 cells.With the concentration increase of the main drug , the colony formation of CNE-2 cells was reduced . The number of colony formation in the negative control group , the radiation group , 10 mg· ml-1 and 20 mg· ml-1 Biyanqing combined with radiation groups (calculated according to the weight of all medicinal material ) was significant different (P<0.05).With the main drug concentration increasing , the percentage of G 2/M phase and apoptotic cells were both increased , and compared with the con-trol group, the difference was significant (P<0.05).Conclusion:Biyanqing granule can not only inhibit CNE-2 cells but also block CNE-2 cells in G2/M to improve the radiosensitization of CNE-2 cells.

Objective To explore effects of endoscopic subtotal thyroidectomy on nodular goiter and its clinical significance.Methods From Jun.2004 to Dec.2009,72 patients with nodular goiter underwent endoscopic subtotal thyroidectomy in Southwest Hospital.Of the 72 cases,22 cases had left-side nodule,31 cases had right-side nodule and 19 cases had bilateral nodules.Single thyroid nodule occurred in 41 cases and multiple nodules in 31 cases.The total number of nodules was 113.The average nodule size was 2.8 cm(ranging from 0.4 to 6.3 cm).Results Of the 72 cases,19 patients underwent bilateral subtotal thyroidectomy and the mean operative time was 97 min(ranging from 80 to 150 min).53 patients underwent unilateral subtotal thyroidectomy and the mean operative time was 65 min(ranging from 25 to 120 min).The mean intraoperative blood loss was 45 ml (ranging from 5 to 120 ml).Of the 72 cases,68 cases were given cervical plexus block regional anesthesia and among them 66 cases(97%)acquired good anesthesia.Temporary hoarse voice occurred in 2 cases and postoperative bleeding occurred in the subcutaneous tunnel of breast in 2 cases.Patients were followed up from 3 to 5years and the cosmetic result was satisfactory.The postoperative review half year later showed that unilateral nodule recurred in 1 case and the recurrence rate was 1.4%.Conclusions Endoscopic subtotal thyroidectomy through anterior chest wall or breast approach under local anesthesia is a safe and effective treatment in nodular goiter.In the process of dissecting thyroid,blunt maneuver and proper use of ultrasonic knife instead of clamping thyroid nodules directly are recommended in order to reduce intraoperative blood loss and enhance safe practice.
