OBJECTIVE:To observe clinical efficacy and safety of Autoserum eye drops in the treatment of filamentary kerati-tis after excimer laser corneal refractive surgery. METHODS:46 patients (90 eyes) with filamentary keratitis after excimer laser corneal refractive surgery were selected and randomly divided into control group and observation group with 23 cases(45 eyes)in each group. The control group was given clearing mesh+wearing soft contact lens+bFGF eye drops;the observation group was giv-en clearing mesh+ wearing soft contact lens + Autoserum eye drops. The clinical efficacy,cure time,recurrence rate and ADR were compared between 2 groups. RESULTS:The total effective rate of observation group was 93.3%,which was higher than that (82.2%)of the control group,with statistical significance(P<0.05);the cure time of observation group was(2.7±1.1)d,which was shortened significantly compared with control group [(3.5±1.2)d],with statistical significance(P<0.05). The recurrence rate of filamentous keratitis was 4.4% in observation group and 15.6% in control group;the observation group was significantly lower than the control group,with statistical significance(P<0.05). During the treatment,there were 1 case(1 eyes)of corneal epitheli-al edema in observation group and 2 cases (2 eyes) of corneal epithelial edema in control group,there was no statistical signifi-cance(P>0.05). CONCLUSIONS:In the treatment of filamentous keratitis after excimer laser corneal refractive surgery,therapy of clearing mesh+wearing soft contact lens+Autoserum eye drops have high total effective rate,low recurrence rate and short cure period with less ADR.

BACKGROUND: Periprosthetic infection after total hip replacement usually results in surgery failure and needs a second operation.OBJECTIVE: To explore the pathogenesis, diagnosis and treatment of periprosthetic infection after total hip replacement by-reviewing and summarizing articles published in recent years.METHODS: A computed-based online search of Pubmed database was performed by using the key words of total hip arthroplasty, infection for manuscripts published from January 1990 to December 2010 and of those in SpringerLink database between January 1,1970 and December 31, 2010. A total of 2 109 manuscripts were retrieved. Moreover, related book or manuscripts that published by high-impact journals were included. Totally, 29 manuscripts were included. RESULTS AND CONCLUSION: The formation of biofilms on the surface of prosthesis is the main cause for hardly eradicated. Resistant bacteria and polymicrobial infection seems to be an increasing tendency. A correct diagnosis as soon as possible is very important to prognosis. However, without a gold-standard way, each mean has advantages and shortages, and comprehensive considerations are necessary. lnterleukin-6 seems a good choice for its inexpensive, non-invasive and a high sensitivity and specificity, which has aroused increasing attention. The antibiotics only, debridement with retention, one-stage replacement, two-stage replacement, joint arthrodesis, even amputation, are used to treat infection after total hip replacement. Prophylactic antibiotics are important to prevent infection. Antibiotic-loaded acrylic cement seems to be reliable and accept for more and more patients. However, each option must be selected according to the presence of infection individually.

Objective To discuss the efficancy of traditional Chinese medicine in treatment of intrahepatic cholestasis of pregnancy .Methods A total of 60 patients who were admitted to our hospital for severe intrahepatic cholestasis of pregnancy(ICP) from January 2009 to December 2012 were randomly divided into two group using random number table .Patients in study group (n=30) took traditional Chinese medicine three times a day plusUDCA twice a day orally .Patients in control Group (n=30)were on‐ly given UDCA twice a day orally .Conventional treatment and care for ICP were given to both groups .Biochemical index (TBA , ALT ,and AST)level ,pregnancy outcome and Caspase‐3 of the two groups were recorded and compared and compared .Results The expressing of Caspase‐3 in placental cytotrophoblast ,syncytiotrophoblast .Decidual cells and interstitial cells of study group were (10 .58 ± 2 .62)% ,(15 .8 ± 4 .02)% ,(10 .17 ± 3 .58)% ,(14 .23 ± 4 .39)% ,respectively ,which were significantly lower than those in control group(P<0 .05) ,which were (20 .46 ± 8 .68)% ,(33 .89 ± 7 .05)% ,(20 .56 ± 4 .23)% ,(28 .29 ± 5 .58)% .TBA ,ALT、AST in two groups were declined ,and ctedy group was better than in control group(P<0 .05) .The index of liver function were all lower in study group than that of control group(P<0 .05) .Incidence rate of neonatal asphyxia was lower in study group than that of con‐trol group (P<0 .05) .Conclusion Traditonal Chinese medicine can reduce the expression of Caspase‐3 in study group .It is safe and eflfective in the treatment of ICP .

The intracranial portion of the vertebral arteries and the basillar artery of 103 Chinese (80 adults and 23 children) brains have been studied. The diameter of the intracranial portion of the vertebral artery on the left side is usually greater than that on the right side. The anterior spinal artery comes off mostly from the vertebral artery. It descends, slants medially and unites with the opposite artery to form a single anterior spinal artery in front of the anterior median fissure of the medulla oblongata. The vertebral artery usually gives off 1～3 medullary branches, which enter the medulla oblongata mostly through the posteriolateral sulcus. The blood supply of medulla oblongata has been discussed.In 57.50?5.53% of the adults, the union of the right and left vertebral arteries to form the basilar artery was found at the level of pons, while in children, 47.83?10.39% was found at the level of the lower border of pons. The labyrinth arteries arise mostly from the anterior inferior cerebellar arteries (77.50?2.95), and in rare cases, from the superior cerebellar or vertebral arteries. The pontine branches coming off from each side of the basilar artery are usually 3～4 in number.

The cerebellar arteries including the arterial supply to the dentate nucleus had been studied on 103 Chinese brians (80 adults, 23 children) by dissection, angiography, clearing method and dissection under stereoscopic microscope. The following results were obtained:1. The superior cerebellar artery which arose mostly from the upper end of the basilar artery near the posterior cerebral artery was one(82.52?2.68％)or two (17.48?2.68％) in number on each side. It was grouped into simple-trunk type (one trunk on each side 69.90?4.52％), double-trunks type(two trunks on each side 4. 86?2.13％), and mixed type (one trunk on one side and two on the other 25.24?4.28％).It passed backward around the cerebral peduncle and was more frequently divided into lateral and medial branches.2. Most of the anterior inferior cerebellar arteries sprang from lower third (66.49?3.29％) and middle third (12.14?2.69％) of the basilar artery. The rest (15.06?2.69％) sprang from posterior inferior cerebellar and vertebral arteries and upper segment of the basilar artery. It was absent in 6.31?1.69％.3. The posterior inferior cerebellar artery arose mostly from the vertebral artery (77.18?2.92％)and was absent in 6.80?1.95％. It formed a loop at its original segment and gave off 1～4 branches to medulla oblongata.4. The middle inferior cerebellar artery was present in 17.48?3.95％ and occurred on both sides in two cases.The course, position, distribution of all arteries mentioned above and their interrelationships were observed.5. The arteries to the dentate nucleus might be derived mainly from the superior cerebellar artery, but the anterior and posterior inferior cerebellar arteries also contributed some branches to it. These branches were found mostly 5～6 in number on the superior surface and 3～5 in number on the inferior surface.

Objective To evaluate the CT findings of the parotid basal cell adenoma and it's diagnostic value.Methods The CT appearances of 10 patients with parotid basal cell adenoma confirmed by histopathology were reviewed retrospectively.The plain and the contrast-enhanced CT scan were performed in all cases.Results The well-defined mass in varied size with marked enhancement in contrast-enhanced CT imagines,in which the CT value increased to 200Hu maximally(average,84Hu),were the pathognomonic CT characteristics of the parotid basal cell adenoma.Conclusion The qualitative diagnosis of the parotid basal cell adenoma could be made based on the CT findings combined with some valuable clinical information before operation.
