Objective To evaluate the indications, effectiveness and complications of vitreoretinal surgery using the 25G transconjunctival sutureless vitrectomy system (TSV25G) under the topical anesthesia. Methods The clinical and follow-up data of 22 eyes of 22 patients undergone vitreo-retinal surgery using TSV25G under the topical anesthesia were retrospectively analyzed. All of the patients were monocular sickened, including idiopathic macular hole in 10 eyes, idiopathic macular pucker in 6, vitreoretinal traction syndrome in 4, and vitreous hemorrhage associated with branch retinal vein occlusion in 2. Peeling of epiretinal membrane and/or internal limiting membrane, intraocular laser coagulation, air-fluid exchange and tamponiding of C 3F 8 were performed according to the condition of diseases. The postoperative follow-up was 1-11 months, with the mean duration of 6.4 months. The effect of analgesia, cooperation with the patients, operative effect and complications in and after the surgery were observed. Results The operations finished successfully in all of the eyes under the topical anesthesia. The operation duration ranged from 20 to 25 minutes with average of 22 minutes. The patients cooperated with the doctor well without any discomfort. Two days after the surgery, edema of the wounded conjunctiva was found, and recovered 7 days later. A light pigment dot on the surface of the sclera could be seen at the first month. The complications included transient increasing of intraocular pressure in 2 eyes, feather-like opacity of lens in 5 eyes, vitreous hemorrhage in 1 eye, and air-bleb under conjunctiva in 2 eyes. No other complications related with the cut were found. The macular hole closed in 9 eyes with idiopathic macular hole, and the other 1 had the smaller but not closed hole. Idiopathic macular pucker, vitreoretinal traction syndrome, and vitreous hemorrhage associated with branch retinal vein occlusion were cured successfully. Conclusions Vitreoretinal surgery using the TSV25G under the topical anesthesia has many advantages such as simple procedure, short operation time, micro-invasion, less complications and rapid revovery, and mainly serves simple manipulation in some simple diseases such as idiopathic macular hole, vitreo-retinal traction syndrome, and simple hemorrhage.

Objective To investigate the value of spectral CT for the discrimination of benign and malignant lung lesions through multi-parameter quantitative measurement.Methods Eighty-one patients who had lung nodule or mass on X-ray or plain CT were scanned using spectral CT,generating iodine concentration,water concentration and 101 sets of monochromatic images.Iodine concentration,water concentration,spectrum energy curve and CT value at 40 keV were measured with spectral post-processing software.70 eligible patients were divided into pneumonia group and tumor group.ANOVA analysis was used for the statistic analysis in two groups.Results The iodine concentration in pneumonia group and tumor group were (1.47 ± 0.17) and (0.77 ± 0.19) g/L (F =203.97,P ＜ 0.05).The slope rates of spectrum energy curve in pneumonia group and tumor group were 1.65 ± 0.27 and 0.88 ± 0.22 (F =161.59,P ＜0.05).The CT values at 40 keV in pneumonia group and tumor group were (139.00 ± 16.25) and (83.29 ± 17.44) HU (F =160.45,P ＜ 0.05),there were significant differences in iodine concentration,slope rates and CT values at 40 keV between two groups.The water concentration in pneumonia group and tumor group were (1021.56 ± 11.68) and (1022.62 ±8.56) g/L (F=0.19,P＞0.05),there was no significant difference.Conclusion Spectral CT technique has very important value for the discrimination of benign and malignant lung lesions.

With high incident of cancer and chronic disease, it is more and more important to develop palliative care; as developing later, there is neither unified palliative care mode and related policy, nor mature assessment collaboration in China. It pointed out that Australia as an advanced country with stable development of palliative care and assessment collaboration, called palliative care outcomes collaboration (PCOC). It expatiated the PCOC on structure,function and operation. China should learn from the mode of Australia palliative care assessment and management collaboration, find references to improve and further develop Chinese palliative care assessment collaboration.

Objective To observe the effect of Duanteng Yimu decoction (DYD) on bone turnover markers of C-terminal telopeptide of type Ⅰ collagen (CTX-Ⅰ) and N-terminal propeptide of type Ⅰ procollagen ( PⅠNP) of adjuvant-induced arthritis (AA) rats. Methods Seventy-two SD rats were divided into 9 groups, and complete Freund's adjuvant was injected into the rats to establish adjuvant-induced arthritis rat model. After medication for 36 days, the pedal swelling, the serum levels of CTX-Ⅰand PⅠNP, and ankle X-ray photographic scores were observed. Results The pedal swelling degrees and ankle X-ray scores in medication groups were lower than those in the model group ( P<0.05). The PⅠNP level had no statistically significance in various groups ( P>0.05). The CTX-Ⅰlevel in low-dose DYD group was decreased (P<0.05). Conclusion Caulis Celastri has two-way effects on CTX-Ⅰlevel of female AA rats, and its side effects can be reduced by Radix Dipsaci and Herba Leonuri, but their antagonism effect will disappear with the increase of the dose of Caulis Celastri.
