AIM: To investigate therapeutic effects of combination therapy for neovascular glaucoma ( NVG) .
METHODS: This retrospective study comprised 34 eyes of 34 patients who suffered from NVG. All patients were assigned to group A, B, C and D according to the different combination therapies. Group A ( 11 eyes of 11 patients ) was treated with intravitreal injection of ranibizumab and panretinal photocoagulation ( PRP ) . Group B ( 10 eyes of 10 patients ) was treated with transcleral cyclophotocoagulation and PRP. Group C ( 6 eyes of 6 patients) was treated with 3 therapies together. Group D (7 eyes of 7 patients) was treated with 810nm transcleral cyclophotocoagulation and soft gas-permeable contact lenses. All the patients were followed-up for 1a. The best- corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) were recorded and analyzed prior to operation and 1, 4wk, 6 and 12mo after operation.
RESULTS: All the post treatment IOP decreased significantly ( P<0. 05 ) from the values before therapy, and the IOP values after 4wk, 6, 12mo were not significantly different ( P > 0. 05 ) in statistics. Most patients' IOP can be controlled below 23mmHg after combination therapy. The visual acuity in group A after 1, 4wk, 6mo compared with those before treatment was significantly increased ( P<0. 05 ) in statistics and other groups did not significantly change before and after treatment (P>0. 05). Anterior chamber bleeding occurred to 2 cases after 1wk of transcleral cyclophotocoagulation. No other ocular or systemic adverse events were found during the follow-up duration.
CONCLUSION: After the combination of intraocular injection of the anti - VEGF drugs, 810nm laser cyclophotocoagulation and PRP, most patients with NVG disease can be effectively treated, can effectively control IOP, and retain part of the visual function, significantly improve the quality of life. In the short - term, combination therapy is safe and effective for NVG, which provides us an available strategy to conquer NVG by simply programmable operation and less suffering.

Objective To study the diagnostic value of calcification in differentiating benign and malignant thyroid lesions. Methods CT images of 318 consecutive patients with pathologically proven thyroid lesions were retrospectively reviewed by two radiologists. The following characteristics of calcification on CT images were evaluated: (1) size (≤2 mm indicating microcalcification and > 2 mm or shelly and irregular shape indicating macrocalcification, and both features indicating mixed calcification), (2) number (single or multiple) and (3)location (internal or edge). χ~2 test was used for statistical analysis. Results Oft he 318 cases, 48 were diagnosed as malignant (papillary carcinoma 26, follicular carcinoma 7, medullary carcinoma 3 and microcarcinoma 12) and 270 were benign (nodular goiter 36, adenoma 170, nodular goiter with adenoma 38 and adenoma with Hashimoto's thyroiditis 26). Calcification was found in 60 cases (18.9%). Among them 21 (papillary carcinoma 12,microcarcinoma 6,follicular carcinoma 2 and medullary carcinoma 1) were malignant(43.8%) and 39(nodular goiter 6, adenoma 13,nodular goiter with adenoma 19 and adenoma with Hashimoto's thyroiditis 1) were benign (14.4%) (P < 0.01). Sensitivity and specificity for diagnosing thyroid carcinoma were 43.8% (21/48) and 85.6% (231/270), respectively. Microcalcification was found in 37 cases (malignant 8, benign 29) and macrocalcification was found in 23 cases(malignant 13, benign 10) (P < 0.01) . Sensitivity and specificity of macrecalcification for diagnosing thyroid carcinoma were 61.9% (13/21) and 74.4% (29/39), respectively. Single calcification was found in 31 cases (malignant 13, benign 18) and multiple calcification was found in 29 cases(malignant 8, benign 21) (P >0.05). Internal calcification was found in 15 cases of malignant lesions(71.4%) and 12 of benign lesions(30.8%); Edge calcification was found in 6 cases of malignant and 27 of benign, (P <0.01). Sensitivity and specificity of internal calcification for diagnosing thyroid carcinoma were 71.4% (15/21) and 69.2% (27/39), respectively. Conclusion Internal calcification or(and) macrocalcification of the thyroid lesions may strongly suspect thyroid carcinoma and fine-needle aspiration or surgery should be further performed.

BACKGROUND:Total knee arthroplasty has matured in clinical treatment. LPS-Flex Mobile Bearing System (Zimmer, USA) artificial knee prosthesis is the high-flexion rotating platform type knee prosthesis. The time of its clinical application in China is short, so its advantages have not been reported. OBJECTIVE:To investigate the preliminary clinical outcome of the total knee arthroplasty with LPS-Flex Mobile Bearing system artificial knee prosthesis (Zimmer, USA), and to assess the biocompatibility of artificial prosthesis and host using range of motion of knee and function after replacement. METHODS:We retrospectively analyzed 37 patients (42 knees) undergoing total knee arthroplasty using Zimmer LPS-Flex Mobile Bearing prostheses (high-flexion rotating platform type knee prosthesis) in The First Hospital Affiliated to Soochow University from February 2012 to March 2014, including 9 males (10 knees) and 28 females (32 knees), aged 47-78 years, averagely 63.7 years. Bone cement fixation was used, and the patel a was not treated with replacement. Postoperative complications were observed. Ranges of motion of knee joint preoperatively and postoperatively were compared. The recovery of knee joint function was evaluated using Hospital for Special Surgery Knee Score. RESULTS AND CONCLUSION:A total of 34 cases (38 knees) were fol owed up for 6-28 months. Range of motion of knee joint improved from 88.5° before operation to 124.2° after operation on average. Hospital for Special Surgery Knee Score improved from 52.5 before replacement to 91.1 after replacement, showing significant differences (P<0.01). Therapeutic effects were assessed according to Hospital for Special Surgery Knee Score:excel ent in 20 cases, good in 16 cases, average in 2 cases, with an excel ent and good rate of 95%. The incidence of various complications was low. These data suggested that short-period clinical outcomes of high-flexion rotating platform type knee prosthesis replacement are satisfactory. This prosthesis has advantages in its design, which is more close to the physical structure of knee joint, but its long-period outcomes deserve further investigations.

Objective To investigate the effect and safety of early intervention and delayed intervention therapy on elderly patients and younger patients with non-ST segment elevation acute coronary syndrome. Methods The patients with non-ST segment elevation acute coronary syndrome were randomly divided into early intervention group (coronary angiography taken within 24 hours after grouping) and delayed intervention group ( coronary angiography taken after 36 hours after grouping). The primary endpoint was a composite endpoint of death, myocardial infarction and stroke during 180 days follow-up. Results A total of 815 patients were enrolled, including 198 elderly patients aged 75 years and above, and 617 younger patients aged below 75 years. The elderly patients had a greater incidence of the primary endpoint than that of younger patients ( P = 0. 00). The primary endpoint of early intervention group were obviously lower than that of delayed intervention group of younger patients ( P = 0. 01 ). There was no significant difference in primary endpoint incidence of early intervention group and delayed intervention group of the elderly patients (P =0. 39). Conclusions The elderly patients with non-ST segment elevation acute coronary syndrome who underwent intervention had greater incidence of death and myocardial infarction. Early intervention reduced the rate of myocardial infarction for the younger patients. There was no significant difference in primary endpoint incidence between early intervention and delayed intervention among elderly patients.

OBJECTIVETo identify the genetic alterations in nonsyndromic cleft lip and palate (NSCLP).
METHODSComparative genomic hybridization was applied to investigate the genomic imbalance (the gain or loss of genetic material) in 7 cases of NSCLP.
RESULTSIt showed that the loss of chromosome DNA copies happened in chromosome 6, 7, 10, 13, 14, 16, 20, 22 and the gain of chromosome DNA copies happened in chromosome 5, 15, 18, 19. Conclusions 13q had a high frequency (71.4%) of chromosome loss.
CONCLUSIONSAbnormal chromosome DNA copies happen in all the patients with NSCLP. Most of the patients have chromosome DNA copies loss. It suggests that loss of inhibitory gene may be related to the NSCLP. The related inhibitory gene may locate in 13q.
