OBJECTIVE: To investigate the clinical application and efficacy of ¹²⁵Ⅰ radioactive seeds implantation in the treatment of recurrent salivary gland carcinoma after external radiotherapy. METHODS: From July 2004 to July 2016, 43 cases of recurrent salivary gland carcinoma of the neck after external radiotherapy or surgery combined with external radiotherapy were treated. According to the conventional segmentation radiotherapy for head and neck cancer (once a day, 1.8-2.0 Gy each time, 5 days per week), the cumulative radiation dose of the patients in this group was calculated. In the study, 26 patients received 50-60 Gy, 7 patients received less than 50 Gy, 4 patients received 60-70 Gy, and 6 patients received more than 80 Gy (range: 80-120 Gy). The interval between the last external irradiation and local recurrence was 4-204 months, and the median interval was 48 months. Among them, 25 cases were treated with ¹²⁵Ⅰ radioactive seeds implantation only and 18 cases were treated with ¹²⁵Ⅰ radioactive seeds implantation after operation. The prescription dose was 100-140 Gy. The control rate, survival rate and disease-free survival rate were recorded to evaluate the side effects. RESULTS: The median follow-up time was 27 months (ranging from 2.5 to 149.0 months). Among them, the median follow-up time of adenoid cystic carcinoma patients was 31 months (range: 2.5-112.0 months), and the median follow-up time of mucoepidermoid carcinoma patients was 18 months (range: 5-149 months). The local control rates for 1, 3 and 5 years were 66.5%, 48.8% and 42.7%, respectively. The 1-, 3- and 5- year survival rates were 88.0%, 56.7% and 45.8%, respectively. The disease-free survival rates of 1, 3 and 5 years were 58.3%, 45.4% and 38.1%, respectively. There was no statistically significant difference in local control rate, survival rate, and disease-free survival between the radioactive seeds implantation group and the radioactive seeds implantation group after surgical resection. There were 2 cases of acute radiation reaction Ⅰ/Ⅱ and 3 cases of reaction Ⅲ or above. In the late stage of radiotherapy, there were 8 cases with Ⅰ/Ⅱ grade reaction and 3 cases with Ⅲ grade or above reaction. The incidence of radiation reactions of Grade Ⅲ and above was 7%. CONCLUSION ¹²⁵Ⅰ radioactive seeds implantation provides an alternative method for the treatment of recurrent salivary gland carcinoma after external radiotherapy. The local control rate and survival rate are improved on the premise of low incidence of side effects.

To investigate the application of diagnosis methods for coronary artery disease (CAD) and the status quo of its syndrome typing. The literature content analysis was used in this study. The frequency statistics was performed by comprehensively collecting CAD (thoracic obstruction) syndrome typing correlated literatures, designing content analysis tables, extracting information such as typing methods, typing elements, and syndrome typing, and so on. Results showed that blood stasis, yin deficiency, qi deficiency, yang deficiency, phlegm turbidity, and other syndrome elements extensively exist in literatures concerning CAD syndrome typing. Modem doctors prefer to use syndrome typing of qi, blood, jinye, and eight principles in syndrome typing of CAD more frequently. The asthenia in origin and asthenia in superficiality has been widely recognized as the basic syndrome of CAD.

OBJECTIVETwo children with hydroa vacciniforme-like lymphoma (HVLL) were reported for a better understanding of this disease.

METHODSThe clinical manifestation, pathological characteristics, therapeutic outcomes of two children with HVLL were analyzed and presented by compared with what described in literatures.

RESULTSTwo children were girls, who treated firstly in the hospital in May 2012, July 2012 and their duration were 1 years, more than 10 years respectively. Their clinical manifestations were both limbs and craniofacial polymorphous rashes. Pathological findings revealed that the dermis and subcutaneous tissue were profiled by atypical lymphocytic infiltration. Immunohistochemistry showed that the infiltration of cells from T/NK cell, and Epstein-Barr virus encoded small RNA (EBER)(+). Case 1 was treated with chemotherapy, but her condition continued to deteriorate. Case 2 just received symptomatic treatment, her skin lesions gradually reduced and rash disappeared completely 2 months later.

CONCLUSIONHVLL is found with special clinical manifestation, its diagnosis mainly depend on skin biopsy and immunohistochemistry, there is no specific treatment method now, and its prognosis still needs further research.

OBJECTIVE: We aimed to investigate the ability of readout-segmented echo-planar imaging (rs-EPI)-based diffusion tensor imaging (DTI) in assessing the microstructural change of extraocular muscles (EOMs) and optic nerves in patients with thyroid-associated orbitopathy (TAO) as well as in evaluating disease activity.MATERIALS AND METHODS: We enrolled 35 TAO patients and 22 healthy controls (HCs) who underwent pre-treatment rs-EPI-based DTI. Mean, axial, and radial diffusivity (MD, AD, and RD) and fractional anisotropy (FA) of the medial and lateral EOMs and optic nerve for each orbit were calculated and compared between TAO and HC groups and between active and inactive TAO groups. Factors such as age, sex, disease duration, mediation, and smoking history between groups were also compared. Logistic regression analysis was used to evaluate the predictive value of significant variables for disease activity.RESULTS: Disease duration was significantly shorter in active TAOs than in inactive ones (p < 0.001). TAO patients showed significantly lower FA and higher MD, AD, and RD than HCs for both medial and lateral EOMs (p < 0.001), but not the AD value of lateral EOMs (p = 0.619). Active patients had significantly higher FA, MD, and AD than inactive patients for medial EOMs (p < 0.005), whereas only FA differed significantly in the lateral EOMs (p = 0.018). The MD, AD, and RD of optic nerves were significantly lower in TAO patients than HCs (p < 0.05), except for FA (p = 0.129). Multivariate analysis showed that the MD of medial EOMs and disease duration were significant predictors for disease activity. The combination of these two parameters showed optimal diagnostic efficiency for disease activity (area under the curve, 0.855; sensitivity, 68.4%; specificity, 96.9%).CONCLUSION: rs-EPI-based DTI is promising in assessing microstructural changes of EOMs and optic nerves and can help to indicate the disease activity of TAO, especially through the MD of medial EOMs.

OBJECTIVESTo analyze the perioperative complications of radical cystectomy using a standardized reporting methodology.

METHODSThe clinical data of 233 cases of radical cystectomy from January 1996 to December 2008 were reviewed. Two hundred male patients and 33 female patients were included. The mean age was 58.9 years old. All complications within 30 days of surgery were recorded and classified using a 5-grade modification of the Clavien system.

RESULTSOverall mean operative time was 339 (170 - 610) minutes, and mean blood loss was 818 (range 100 to 3500) ml. Of the 233 subjects at least 1 postoperative complication developed in 84 (36.1%), including five cases of intraoperative complications. According to the modified Clavien system, 27 patients (11.6%) had grade 1, 38(16.3%) had grade 2, 16(6.9%) had grade 3, and 3(1.7%) had grade 4 complications. The most frequent complication was gastrointestinal complications (15.9%), then the incision-related complications (15.0%) and lung infections (4.7%). An association between hypoproteinemia and any complication was found after adjusting for confounding variables (OR = 2.963, 95%CI: 1.451 - 6.050, P = 0.003), and American society of anesthesia score (ASA score) was significantly associated with any major complication (OR = 2.520, 95%CI: 1.003 - 6.332, P = 0.049).

CONCLUSIONSRadical cystectomy is associated with a high perioperative complications, using the modification of the Clavien system has allowed us to stratify complications during radical cystectomy. Hypoproteinemia is independently associated with any complication in these patients and ASA score was significantly associated with any major complication.

The purpose of this study is to develop glipizide push-pull osmotic pump (PPOP) tablets by using a formulation design expert system and an artificial neural network (ANN). Firstly, the expert system for the formulation design of osmotic pump of poor water-soluble drug was employed to design the formulation of glipizide PPOP, taking the dissolution test results of Glucotrol XL as the goal. Then glipizide PPOP was prepared according to the designed formulations and the in vitro dissolution was carried out. And in vivo evaluation was carried out between the samples which were similar to Glucotrol XL and the Glucotrol XL in Beagle dogs. The range of the factors of formulation and procedure, which could influence the drug release, was optimized using artificial neural network. Finally, the design space was found. It was found that the target formulation which was similar to Glucotrol XL in dissolution test could be obtained in a short period by using the expert system. The samples which were similar to Glucotrol XL were bio-equivalent to the Glucotrol XL in Beagle dogs. The design space of the key parameter coating weight gain was 9.5%-12.0%. It could be concluded that a well controlled product of glipizide PPOP was developed since the dissolution test standard of our product was more strict than that of Glucotrol XL.

OBJECTIVETo evaluate the effificacy of dual antiplatelet therapy combined with Naoxintong Capsule ([see text], NXTC) in a rat model of coronary microembolization (CME).

METHODSA total of 95 rats were randomly divided into 6 groups: control, sham-operation, CME model, NXTC, dual antiplatelet (clopidogrel and aspirin) intervention (DA), and NXTC combined with DA (NDA) groups. The complete data in 69 rats were obtained. The number of CME, myocardial apoptosis rate, bleeding time, clotting time, and adensosine diphosphate (ADP)-induced platelet aggregation were assessed.

RESULTSCompared with the CME group, the number of CME and myocardial apoptosis rates were signifificantly decreased in the NXTC, DA, and NDA groups (P <0.01). Compared with other intervention groups, the number of CME and myocardial apoptosis rates were the least in the NDA group (P <0.01), and the incidence of surgical bleeding was the highest in the DA group (P <0.01). Compared with the CME group, ADP-induced maximum platelet aggregation rate was significantly inhibited in the NXTC, DA, and NDA groups (P <0.01), both bleeding time and clotting time were signifificantly increased in the NXTC, DA, and NDA groups (P <0.01), while the above parameters were the highest in the DA group (P <0.05).

CONCLUSIONThe combination therapy of NXTC and DA enhanced the anti-CME effect of either therapy alone and reduced the risk of the DA therapy-associated bleeding, demonstrating an improved benefifit/ risk ratio in the rat model of CME.
