The changes of pathophysiology of perihematomal tissue after intracerebral hemor- rhage are extremely complicated.Studies in recent years have suggested that perihematomal tissue does exist many changes of pathophysiology and molecular biology,such as mass effect of hematoma,hematoma components damage to perihematomal tissue,hemodynamic changes, neuropeptide Y and matrix metalloproteinase changes,etc.

In 1970′s a prevailing hypothesis postulated herpes simplex virus in cervical cancer aetiology,but Hausen has made seminal observations that identify novel human papilloma viruses as key contributors to cervical cancer and hybridization technique of nucleic acid has proven it.After the discovery of human immunodeficiency virus(HIV) by Sinossi and Montagnier,they held the evolutional history of HIV.The article objectively evaluates the role in the discovery of HIV,played by Gallo.

AIM:To observe the transplantation of acellular porcine corneal stroma on the treatment of superficial keratitis by drug-resistant fungal.METHODS:We performed a retrospective analysis of 16 cases of fungal keratitis received the transplantation of acellular porcine corneal matrix from June 2015 to March 2016 with a follow-up of 6mo.We analyzed on items as postoperative visual acuity, corneal graft status, postoperative recurrence and postoperative complications.RESULTS:We observed a healing time of corneal epithelium in 7 to 10d postoperatively generally and the absence of corneal edema in 1mo, while the cornea gradually returned transparent in the 16 cases.Two cases required medication for an epithelial recovery and 3 cases received intervention for decreasing intraocular pressure to a certain level.During the follow-up we observed no cases of cornea degeneration, recurrence of infection or rejection.The vision acuity showed 1.27±0.22, 1.11±0.13, 0.79±0.22 in 1, 3 and 6mo after operation respectively.There was no statistical difference between vision in 1mo and the vision before surgery (P=0.06);while we found a statistical difference when comparing the vision of 3 and 6mo with vision before surgery (P=0.01,0.001).The vision in 6mo increased with a statistic difference to the vision at 1 and 3mo (P<0.001) while no statistic difference was observed between 1 and 3mo(P=0.11).CONCLUSION:Transplantation of acellular porcine corneal matrix is a safe and efficient treatment for fungal keratitis.

This review introduced the research progress of covalent modification strategies in local anesthetic drug delivery systems. As a commonly used and multimodal analgesic drug, local anesthetics have limited duration of action and potential toxicity in clinical application. In order to prolong the analgesic effect and reduce systemic toxicity, researchers are committed to the development of sustained-release local anesthetics with long-lasting dose-controlled-release functions. When it comes to the delivery of local anesthetics, the covalent modification strategy is a key approach. By covalently binding drugs to large molecule carriers, covalent modification strategies can improve drug stability, targeting and delivery efficiency. Macromolecular prodrugs can modulate the kinetic process of the drug, so that the drug is released in the form of the active ingredient and achieve better therapeutic effects. In recent years, stimulus-responsive macromolecular prodrugs have become a research hotpot for local anesthetic drug delivery systems, and the stimulus-responsive performance of macromolecular prodrugs can rapidly release drugs under internal and external stimulus conditions, and maintain low toxicity and high efficiency in blood circulation and normal tissues. These emerging research directions provide important guidance for prolonging the analgesic effect of local anesthetics and reducing systemic toxicity, and provide new idea for the development of more effective drug delivery systems in the future.

Objective To study the efficacy of late course accelerated fractionation(LCAF) radio- therapy in the treatment of nasopharyngeal carcinoma(NPC).The end-po s were local control,radiation-in- duced complications,factors influencing survival.Methods From December 1995 to April 1998,178 NPC patients were admitted for radiation treatment.The radiation beam used was ~(60)Co?or 6 MV X-ray.For the first two-thirds of the treatment,two daily fractions of 1.2 Gy were given to the primary lesion ,with an interval of≥6 hours,5 days per week to a total dose of 48 Gy/40 fractions,over a period of 4 weeks.For the last one third of the treatment,i.e.beginning from the 5th week,an accelerated hyperfractionation schedule was carried out.The dose per fraction was increased to 1.5 Gy,2 fractions per day with an interval of≥6 hours,the total dose for this part of the protocol was 30 Gy/20 fractions over 2 weeks.Thus the total dose was 78 Gy in 60 fractions in 6 weeks.Results All patients completed the treatment.Acute mucosi- tis:none in 2 patients,Grade 1 in 43,Grade 2 in 78,Grade 3 in 52,and Grade 4 in 3 patients.Local control rate:the 5-year nasopharyngeal local control rate was 87.7%,and the cervical lymph node local control rate was 85.7%.The 5-year distant metastasis rate was 26.1%,and 5-year survivals was 67.9%. Sixteen patients had radiation-induced cranial nerve palsy.Conclusions With this treatment schedule, patient's tolerance is good,local control and 5 year survivals are better than control groups of conventional fractionation and hyperfractionation radiotherapy.Radiation-related late complication does not increase.Ran- domized clinical trials are being carried out to further confirm the efficacy of LCAF for nasopharyngeal carci- noma.

Objective To observe tigecycline (TGC),minocycline (MH)and polymyxin B (PB)in vitro antibacterial activity of pan-resistant Acinetobacter baumannii (PDR-Ab)for clinical treatment,provide the basis for infection control.Methods Collected 76 patients’clinical specimens used for no repeat count of isolation and identification with pan-resistant Acineto-bacter baumannii in Shaanxi Provincial People’s Hospital from October 2013 to March 2013.Used tigecycline,minocycline and polymyxin B to do susceptibility testing with disk diffusion method (KB).Results 76 pan-resistant Acinetobacter bau-mannii ,sensitive to the rate for tigecycline and polymyxin B were 100% sensitivity rate of minocycline and intermediary rates were 67.11%,27.63%.Conclusion Tigecycline,minocycline and polymyxin B for the Pan-resistant Acinetobacter bau-mannii had good in vitro antibacterial activity.It provide a reference for clinical pan-resistant Acinetobacter baumannii infec-tions caused by diseases treatment.

Objective To investigate the clinical efficacy of intraoperative methylprednisolone used in combination with perioperative enteral nutrition support in improving liver synthetic function after hepatectomy and postoperative recovery.Methods In this prospective controlled trial,79 patients treated with hepatectomy at Departement of Hepatobiliary Pancreatic Surgery in Drum Tower Hospital between June 2013 and May 2014 were included and divided into control group (n =39) and steroid group (n =40) according to the order of surgery.The control group underwent hepatectomy only,while the steroid group received intraoperative methylprednisolone (500 mg) at the start of liver excision.Both of the two groups were given the same perioperative enteral nutrition support.Liver function,prealbumin (PA),and C-reactive protein (CRP) levels were measured before and on days 1,3,and 5 after the operation.Human blood albumin infusion volume,postoperative gas passing,postoperative hospital stay,and incidence of complications were recorded.Results The serum level of PA on day 3 after hepatectomy was significantly higher in the steroid group than in the control group [(101.26 ±61.17) mg/L vs.(81.84 ±43.58) mg/L,t =-1.607,P =0.049].The serum level of cholinesterase on day 1 after hepatectomy was significantly higher in the steroid group than in the control group [(5.60±1.54) kU/Lvs.(4.68±1.01) kU/L,t=-3.136,P=0.004].On day1 and day 3 after hepatectomy,the serum levels of CRP were significantly lower in the steroid group than in the control group [(41.79 ±20.86) mg/L vs.(62.08 ±38.33) mg/L,t =2.933,P=0.027;(64.14 ±32.38) mg/L vs.(102.64 ± 49.05) mg/L,t =4.127,P =0.006].The postoperative hospital stay was significantly shorter in the steroid group than in the control group [(12.62 ±5.74) d vs.(15.41 ± 10.00)d,t =1.514,P =0.002].Conclusion Intraoperative use of methylprednisolone combined with perioperative enteral nutrition support may inhibit postoperative inflammatory response,promote early recovery of liver synthetic function,and help to promote rehabilitation after hepatectomy.
