Objective To evaluate the clinical significance of monitoring of D‐dimer ,fibrinogen and fibrin degradation products after hip replacement for diagnosing and preventing the lower extremity deep venous thrombosis .Methods A total of 66 cases of patients who carried out hip replacement from April 2013 to April 2015 in the department of orthopaedic in this hospital were se‐lected .Patients complicated with lower extremity deep venous thrombosis were enrolled into the observation group ,while patients without lower extremity deep venous thrombosis were enrolled into the control group .Levels of D‐dimer ,fibrinogen and fibrin deg‐radation products were strictly monitored after hip replacement and were comparatively analysed .Results There were no statisti‐cally significant differences in levels of fibrinogen and fibrin degradation products between the two groups (P>0 .05) ,while statisti‐cally significant difference was found in level of D‐dimer between the two groups(P<0 .05) .Conclusion The monitoring of D‐di‐mer ,fibrinogen and fibrin degradation products after hip replacement could have clinical significance for diagnosing and preventing lower extremity deep venous thrombosis .

Objective To explore the compatibility rules of acupoints and meridians in acupuncture-moxibustion treatment for vertigo, by using the association rules of data mining.Method The relevant data were collected from literatures about acupuncture-moxibustion in treating vertigo from the Pre-Qin Period to Qing Dynasty to establish a database. Then the involved acupoint and meridian groups were further extracted by using association rules of data mining.Result Shangxing (GV 23) and Fengchi (GB 20), Fenglong (ST 40) and Jiexi (ST 41), Hegu (LI 4) and Fengchi (GB 20), Fenglong (ST 40) and Fengchi (GB 20), Waiguan (TE 5) and Zulinqi (GB 41), Hegu (LI 4) and Fenglong (ST 40), Hegu (LI 4) and Jiexi (ST 41), Yanggu (SI 5) and Zulinqi (GB 41), Yanggu (SI 5) and Fengchi (GB 20), Shenting (GV 24) and Shangxing (GV 23) are the most commonly used acupiont pairs; the Governor Vessel, Gallbladder Meridian and Bladder Meridian are the most commonly used meridian groups.Conclusion It’s reasonable to use association rules to study the ancient acupuncture-moxibustion literatures, and the results about acupoint and meridian groups provide references for both clinical practice and experimental researches.

Objective To explore CT and MR radiological characteristics of atypical hemangiomas of the liver (AHL). Methods The CT and MRI findings of 6 patients with pathologically proven AHL were retrospectively analyzed. Results The common radiological findings of hemangiomas of the liver included: (l)The lesions were oval-shaped with smooth outline. (2) The lesions were of slightly hypodense on plain CT scan. On MRI scan, the lesions showed slightly low signal with T1WI and high signal with T2WI, and the lesions had central scars. (3) On dynamic contrast-enhanced CT or MRI scan, the lesions had peripheral nodular enhancement and a centripetal gradual fill-in pattern without enhancement of the central scars. The special radiological features of AHL included: (l)Necrotic or cystic changes and calcification could be found in the central scars. (2) Hemorrhage could also be observed in the lesions though it was rare; they had enhanced CT signal and aberrantly short Tl and T2 signals. (3)The lesions might compress the hepatic parenchyma,biliary and vascular structures, leading to secondary changes such as deformity, abnormal bloody supply, and bile duct obstruction. Conclusion Diagnosis of typical hemangiomas of the liver is not difficult. But more observation and analysis are needed to diagnose AHL.

Leydig cells derived from a SD rat aged one month were transplanted to the hind leg subcutaneous of a 2 week-castrated outbred rat. At 1, 3, 4, 6 months after implantation, the grafts were removed and taken to have a histochemical staining for 3?-hydroxygsteroid dehydrogenase (3b-HSD), light and electron microscopy. The results indicated that there were a lots of 3b-HSD positive leying cells in the grafts. The well revascularized and no lymphocytic infiltration were seen around the implanted cells with 4 months after transplantation. Electron microscopy displayed that the implanted cells had abundant mitochondria and smooth endoplasm reticulum, suggesting that the implanted ceils could survive and had better secretary testosterone function for 4 months.

0.05 statistically,and we believe that the method of multiple micro-sampling has no effect on detecting the iron and element contents in VH samples of the died rabbit.

The da Vinci robotic surgical system has the advantages of three-dimensional vision and high degree of accuracy,flexibility and repeatability,which makes surgical procedures such as digestive tract anastomosis easier to conduct under minimally invasive conditions.In this article,the feasibility and principle of digestive tract anastomosis and the procedures of pancreaticojejunostomy and pancreaticogastrostomy by the da Vinci robotic surgical system are introduced,so as to improve the quality of anastomosis and reduce the incidences of postoperative complications.Compared with traditional laparotomy,da Vinci robotic surgical system simplified the surgical procedures and reduced the trauma,which is suitable for digestive tract anastomosis in pancreatic surgery.The method of pancreatic anastomosis should be selected in consideration of the condition of patients,surgical procedure and the experience of surgeons.

Precision medicine is a new developing area of medical research and clinical practice, which is stemmed from the urgent need for high-profile medical health care and fast emergence of exquisite biological and medical technologies.Precision medicine, mainly based on the individualized molecular medicine and sophisticated medical techniques, offers multiple dimensional imaging examinations and biological molecular assays to make subsequent therapeutic strategies much more optimized to the personal disease characteristics than the traditional regimes, hence pursuing maximized efficacy and minimized side effects.The precision medicine in China is stepping into a vigorously developing stage after its first official initiation.This review summarized the development and program design of precision medicine in China to shed light on this growingly progressing area.

Objective To assess the operation time of laparoscopic operation for acute cholecystitis by Meta analysis.Methods The methods of computer literature retrieval and manual search were used to collect the research on the timing of laparoscopic surgery for acute cholecystitis in recent years,and the random effects model was used to conduct the Meta analyze.The quality of the literature was evaluated,and then the RevMan5.0.21 software was used to calculate the RR value and 95%CI of the operation time,bleeding volume and postoperative complications.Results A total of 13 articles were included in the Meta analysis,9 in Chinese,4 in English,2535 for a total number of cases,1401 in the early operation group,1134 in the delayed operation group,and 10 papers for low risk of bias,3 papers for bias risk.Meta analysis of the random effects model showed that the operation time of the early operation group was significantly shorter than that of the delayed operation group(P=0.00,RR=-20.25,95%CI=-24.97~15.33),and the intraoperative blood loss was also significantly reduced(P=0.00,RR=-12.58,95%CI=-29.36~5.78),then the postoperative complications were also significantly reduced(P=0.00,RR=0.63,95%CI=0.47~0.84).Conclusion The use of laparoscopic operation in the treatment of acute cholecystitis in patients with 72h could not only shorten the operation time and reduce the amount of bleeding,but also had a significant effect on reducing postoperative complications.

HIV-1 integrase enzyme is a 32kDa protein encoded by HIV pol gene. It is responsible for integration of viral cDNA into host chromosomal DNA, which is indispensable for HIV replication.Since there was no functional equivalent for this enzyme in human cells, inhibition of integrase will bring little side effect to human body. Thus HIV integrase has become an attractive and rational target for therapy of AIDS after reverse transcriptase and protease.The Recent research on HIV-1integrase structure,inhibitors and new therapeutic method target at HIV integrase was reviewed.
