Objective To explore the therapeutic efficacy and operation experience of Prolene Hernia System (PHS) in the tension-free repair operation of inguinal saddle hernia. Methods All 41 cases using PHS were selected as the subjects of this study and the results were analyzed. Results All patients were performed operation under the local anesthesia, and lasted from 25 min to 60 min. They had been keeping in ward for observation from 24 h to 72 h. No serotal swelling, hematoma, and incisional wound infection hap-pened after the operation. The follow-up time had been lasting from 6 months to 42 months, and none of pa-tients catehed a relapse or had the sensation of the foreign bodies. Conclusions Using PHS is safe and ef-fective in the tension-free repair operation, and it is more suited to inguinal saddle hernia. The key of opera-tion success is attaching importance to operation skills.

BACKGROUND: Endothelium-dependent vasodilatation (EDD) has been assessed by intracoronary acetylcholine infusion and digital subtraction angiography. However, its applications in continuous observing on early onset, progression and outcomes of clinical interventions of the disease are limited due to the potential trauma of the method. OBJECTIVE: This study was designed to assess the changes in brachial EDD in patients with hyperlipidemia using high-resolution ultrasound and to compare the outcomes of the patients to those of the healthy individuals. DESIGN: Case-control study SETTING: This study was carried out at the Cardiology Department and the Ultrasound Department of Xinyang CentralHospital PARTICIPANTS: Sixty patients with hyperlipidemia, 37 males and 23females, with an age ranging from 36 to 75 years old, were selected at the Cardiology Department of Xinyang Central Hospital from May 2001 to March 2002. They were divided into 3 groups according to abnormalities in blood lipid, as hypercholesterolemia group (HC, 20 cases),hypertriacylglycerolemia group (HTG, 20 cases) and mixed hyperlipidemia group (HLP,20 cases). Twenty voluntary individuals with normal physical examination findings were allocated into control group, 12 males and 8 females. Informed consents were obtained from all the eligible. METHODS: The brachial artery inner diameter and the changes in blood flow of the brachial artery were assessed using high-resolution ultrasound.After the patients having a rest for more than 10 minutes, the inner diameter (D0) and the baseline blood flow of their brachial artery were measured. The blood pressure cuff was placed under the elbow with a pressure at 300 mm Hg, lasting for 4 to 5 minutes and followed with a sudden deflation. 15 s after deflation, the reactive brachial artery inner diameter (D1) and the blood flow of the brachial artery were detected. The patients took another rest for more than 15 minutes and after the artery restored to a normal condition,the patients took nitroglycerol sublingually at a dose of 400 μg. Three to four minutes later, the brachial artery inner diameter (D2) and the blood flow of the brachial artery were detected. The increasing rate of the inner diameter of brachial artery were calculated, the increasing rate of reactive brachial artery inner diameter (%)= (D1-D0)/D0×100% and the increasing rate of post-treatment brachial artery inner diameter (%)=(D2-D0)/D0 ×100%.Meanwhile, the increasing rate of reactive blood flow (%)=(reactive blood flow-baseline blood flow)/ baseline blood flow (100% and the increasing rate of post-treatment blood flow (%)=(the post-treatment blood flow-baseline blood flow)/baseline blood flow×100%. MAIN OUTCOME MEASURES:In three hyperlipidemia groups and the control group, the inner diameter of the brachial artery were measured under resting conditions, in reactive congestion status and after sublingual nitroglycerol treatment respectively using high-resolution ultrasound. RESULTS: All the 60 patients with hyperlipidemia and 20 healthy controls entered the analysis procedure. In HC group, HTG group and HLP group, the increasing rate of reactive brachial-artery inner diameter were significantly lower than that in control group [(5.7±3.2)%, (5.4±3.0)%,(3.8±2.4)%, (11.3±3.1)%,P < 0.05], which was most significant in HLP group. The increasing rate of both the reactive and the post-treatment blood flow in three experimental groups and the increasing rate of the post-treatment brachial-artery inner diameter were not significant (P > 0.05). CONCLUSION:EDD were impaired significantly in patients with hyperlipidemia. High-resolution ultrasound is capable of assessing EDD accurately and reliably.

Surgery is so far the most widely used and effective treatment of neoplastic diseases.However,residual tumour cells during surgery remain a major trigger of cancer recurrence and matastasis.Although intraoperative rapid pathological R0 resection can be achieved based on preoperative imageological examination,but for small satellite lesions and the naked eye can not find the error quickly and so often cause pathological presence of residual tumour cells.Thus,quick and accurate identification of residual cancer cells is crucial for prognosis of cancer patients.Indocyanine green (ICG) is a new type of fluorochrome that can stain tumours under the near-infrared fluorescence during surgery,the paper will be reviewed latest developments in the reagent for fluorescence in tumours.

Objective To understand the status of soil?transmitted nematode infections in rural residents so as to provide the evidence for formulating the guidance for prevention and control of the diseases. Methods The national surveillance sites of soil?transmitted nematode infections were established in Shuyang County,Suqian City,Jiangsu Province from 2006 to 2015. At least 1 000 fecal samples of residents aged 3 years or above were collected in every autumn,and the intestinal helminth eggs were detected with the Kato?Katz technique and the Enterubius vermicularis eggs were detected by the cellophane tape method for children aged 3-12 years. The soil samples were collected from vegetable fields,lavatories,courtyards and kitchens to exam?ine Ascaris lumbricoides eggs and larvae of hookworm. Results The infection rates of soil?transmitted nematodes in residents and E. vermicularis in children reduced from 1.81%(19/1 049)and 4.72%(5/106)in 2006 to 0.25%(3/1 180)and 0(0/263) in 2015,respectively,in the surveillance sites. The infection intensity was mild in all the infected cases. The soil samples were negative for detecting A. lumbricoides eggs and hookworm larvae. Conclusion The infection rates of soil?transmitted nema?todes in the residents and E. vermicularis in the children show a decreasing trend and keep at a low level of prevalence in Shuy?ang County.
