Objective To investigate the clinical characteristics, diagnosis and treatment of acute mesenteric venous thrombosis(MVT) in the elderly. Methods The clinical features, diagnosis, treatments and prognosis of 10 aged cases with acute MVT were retrospectively analyzed. Results The chief complaints of the 10 cases were different degrees of abdominal pain, which not paralleled with abdominal signs. The accompanying symptoms were nausea, vomiting and bloody stools and so on. All of these patients were misdiagnosised as pancreatitis, appendicitis or intestinal obstruction and so on. diagnosis of two cases was confirmed by ultrasound, 8 by CT. At the same time, 2 cases underwent angiography examination. Of the 8 cases who underwent operation, 5 cases were cured, 3 cases died (1 died of toxic shock and 2 died of multiple organ failure ). Two cases underwent conservative intervention thrombolysis. Conclusions It is essential to improve the knowledge of acute MVT,especially its intricate clinical characteristics, high rates of misdiagnosis and mortality. Early proper diagnosis is crucial. The main treatment is operation and conservative intervention thrombolysis can be performed in the patients whose bowel has not necrosed yet.

Objective To investigate application of modified abdominal closure technique by an all layer in ventro-pelvic part operation and evaluate its value and significance. Methods 3200 cases with ventre-pelvic part operation between May 2002 and Aug 2007, were subjected to single layer closure with non absorbable suture material. The clinic data and some results of follow-up were retrospectively analyzed. Results Operative incisions of 1780 (55.6%) cases were in epigastric zone and their rate of primary healing was 98.5%, others (44.3%) in hypogastric zone (including pelvic cavity) and rate of primary healing was 98.2% (P>0.05). Rate of primary healing in older age-group was 97.9% and control group 98.8%, and primary healing of group diabetes 97.4%, control group 98.2% (P > 0.05). Average time of abdmenal closure was only 11±4 min. Primary complications included dehiscence of wound (0.5%), infection (1.4%) and incisional hernia (0.2%). Follow-up (66%) was performed at 30 days, 3 and 6 months, and at 1, 2 and 3 years. Conclusion It is concluded that closure of an abdominal incision can be effected by a multifilament interrupted absorbable sutures without an increased risk of wound dehiscence or incisional hernia, meanwhile economic and fast. It is the optimal method of abdominal closure and can be generalized.

Objective: To observe the clinical efficacy of moxibustion therapy plus Liu's pediatric massage (tuina) for children with recurrent respiratory tract infections due to qi deficiency of spleen and lung. Methods: A total of 60 children who met the inclusion criteria were divided into an observation group and a control group according to the visiting sequence, with 30 cases in each group. Children in the observation group were treated with moxibustion therapy plus Liu's pediatric massage, and those in the control group were treated with Liu's pediatric massage alone. The incidence of respiratory tract infections and traditional Chinese medicine (TCM) symptoms score were observed and recorded in both groups before and after treatment. And the clinical efficacy was compared between the two groups. Results: The total effective rate of the observation group was 93.3％, and that of the control group was 83.3％. The difference between the two groups was statistically significant (P<0.05). After treatment, the TCM symptoms score and total times of infections in both groups were all statistically different from those before treatment (all P<0.05). The differences in TCM symptoms score and infection frequency before and after treatment in the observation group were statistically different from those in the control group (both P<0.05). Conclusion: Moxibustion therapy plus Liu's pediatric massage has a better effect in improving the clinical symptoms and reducing the frequency of respiratory tract infections for children with recurrent respiratory tract infections due to qi deficiency of spleen and lung than the pediatric massage alone.

OBJECTIVEHeadspace solid-phase microextraction (HS-SPME) was used pre-concentration procedure for the determination of tetrahydrofuran in urine by gas chromatography with hydrogen flame detector.

METHODSSeveral parameters controlling SPME was studied and optimised: SPME fiber, extraction time and extraction temperature, desorption time and desorption temperature.

RESULTSUnder optimal conditions, the correlation coefficient was 0.9998 and good recoveries (range from 93.0% ∼ 100.8%) were achieved, the detection limit was 0.5 µg/L.

CONCLUSIONThe method can be applied to the determination of trace amount of tetrahydrofuran in urine.

Currently, chemotherapy is one of the main therapy for cancer. But the traditional antitumor drugs are systemic distribution in vivo, they are difficult to achieve an effective drug concentration in the tumor tissue and don't have the ability to distinguish normal cells and tumor cells by themselves, that cause systemic toxicity easily and can not meet the clinical needs. With the research on mesoporous silica nanoparticles (MSNs) deepening, more and more attention in the drug delivery system have been payed to in recent years, because of its unique physicochemical structure characteristics, it has the effect on specific targets, directly inhibits the tumor cell growth, reduces the side effects to normal cells, tissues and organs and can be long-term medication, etc. It is expected to be excellent carriers of antitumor drugs. MSNs application in the field of cancer treatment has now become a hot research field of medicine. In this paper, the latest research about MSNs in antitumor drugs targeting delivery system from 2008 to 2015 is summarized, including the application of MSNs separately in antitumor drug targeting, passive targeting, active targeting, physical or chemical conditions response targeting and other compound targeting drug delivery system. We expect it to provide a reference to the toxicity reducing and efficacy enhancing and further development of chemical medicine, natural medicine and monomeric compound of chinese herbal medicine.

The effectiveness and safety of acupuncture-moxibustion for the treatment of agrypnia was systematically reviewed. The clinical randomized controlled trial (RCT) of acupuncture-moxibustion for agrypnia were collected. The literature and document on acupuncture-moxibustion RCT for the treatment of agrypnia that published from January of 2001 to March of 2012 was searched with computer in PubMed, CNKI, Wanfang and VIP database. According to Cochrane Handbook 5. 1. 0, the bias risk and quality assessment were performed on every included trial and RevMan 5. 0 software was applied to make the Meta analysis. Totally 14 researches were included, involving 2662 cases. The Meta analysis showed that the differences of total effective rate between acupuncture-moxibustion and clinical routine treatment were significant [RR = 1.16, 95% CI (1.12, 1.19), Z = 9.32, P < 0.000 01]. The results indicate that total effective rate of acupuncture-moxibustion for agrypnia is obviously superior to that of clinical routine treatment, meaning clinical efficacy of acupuncture-moxibustion is served credit.
