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.

Objective To study the ultrasonographic changes and blood flow characteristic ofthromboangiitis obliterans (TAO) by two-dimensional ultrasound and color Doppler imaging MethodForty-seven vessels of 40 patients with clinically suspected TAO vascular detected with two-dimensionalultrasound and color Doppler,and comparison with CT imagmg.Results Color Doppler imaging couldvisualize the arterial wall and blood flow echo filling case,and the spectrum showed the hemodynamicchanges.Conclusions Color Doppler is the first choice for the secondary check to the noninvasivethromboangiitis obliterans,close to the result by an angiography that is usually regarded as a sensitive,accurate and convenient diagnostic method.

Objective To explore the diagnostic value of abdominal aortic aneurysm (AAA) with 16-slice spiral CT.Methods Forty patients with AAA were examinated with 16-slice spiral CT. Multiplanar reformation (MPR), maximal intensity projection (MIP) and volume rendering (VR) were performed in all cases.Results Forty patients with AAA included seven cases of cystiform, twenty-three cases of shuttle and ten cases of shuttle-cystiform aneurysm. There were three cases of multiple abdominal aortic aneurysm. There was one case of pseudoaneurysm after the rupture of true aneurysm. MPR definitely revealed the site, modality and extent of aortic disease and demonstrated the mural thrombus in the aneurysm. The calcifications of abdominal aortic aneurysm’s wall or in mural thrombus were well depicted by MIP. VR definitely showed the relationship between aneurysm and arterial branches with three-dimension form.Conclusion 16-slice spiral CT is the optimal imaging technique in diagnosing, following up pre-and post-operation of abdominal aortic aneurysms.

In recent years, there is some new recognition about the origin of prostatic carcinoma, prostatic carcinoma has been considered as a stem cell disease. Prostate cancer stem cells have close relationship with prostatic carcinoma formation, advancement, relapse, metastasis and drug resistance. As the development of science and technology continues, studies on the isolation and correlated phenotype identification of prostate cancer stem cells have lead us to further recognize prostate cancer stem cells, as well pave a new way for the diagnosis and therapy of clinical prostatic carcinoma.

Objective To explore surgical technique and clinical outcome of transabdominal preperitoneal hernia repair(TAPP)and totally extraperitoneal hernia repair(TEP)in inguinal hernia repair.MethodsThe clinical data of 23 patients underwent laparoscopic herniorrhaphy were retrospectively analyzed.Nine patients were underwent TAPP,and 14 patients underwent TEP.ResultsNone of patients was changed to open operation.Only one patient of TEP was changed to TAPP.Average operative time was(82.1?40.6)min.Blood loss was(5.7?3.0)ml.Disruption of peritoneum happened to 2 patients underwent TEP.The rate of postoperative complications was 21.7%(5/23),which included serum swelling(1 case),scrotal emphysema(2 cases),transient neurapraxia in the area of repair(1 case)and urinary retention(1 case).No chronic pain,foreign body sensation and infection were found.Average hospitalization after operation was(4.3?0.9)d.No recurrence was observed during a follow-up period of 1-15 months.ConclusionLaparoscope herniorrhaphy is safe due to lower recurrence and complications.It also has the advantages of slight pain and rapid recovery.

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.
