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.

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.

Testicular microlithiasis (TM) refers to the calcium deposits within the seminiferous tubules. Owing to the wide use of scrotal ultrasonography, more cases of TM have been diagnosed clinically. TM can be associated with many conditions, including cryptorchidism, infertility, varicocele, testicular torsion, Klinefelter's syndrome, intratubular germ cell neoplasia (IGCN) and testicular germ cell tumor (TGCT), and its frequent association with IGCN, TGCT and infertility is the particular concern of urologists and andrologists. The etiology of TM is not yet certain. Its biological meaning and clinical significance have not been well defined. Currently, there are controversies on the correlation of TM with IGCN, TGCT and infertility. This article reviews the definition, prevalence, etiology, and histopathology of TM, and summarized its association with IGCN, TGCT, and male infertility as well as the management of the disease.

Noise of ECP (external counterpulsation) comes from the frequent movement of the electromagnetic valve iron core hitting the top of the valve body and the orifice of the bottom, and the high pressure and large air stream rubbing the orifice. This article studies the method to reduce mechanical noise of the electromagnetic valve core, that is to reduce the above movement energy and the hitting force. The method is used in ECP devices with grafying results. This noise controlling technology may reduce the noise of the electromagnetic valve from higher than 50dB to less than 25dB.

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.
