Objective To study the therapeutic effect of pingyangmycin local injection under suspension microlaryngoscopy for treatment of laryngopharyngeal and laryngeal hemangioma. Methods The total of 44 cases of patients with laryngopharyngeal or laryngeal hemangioma were randomly divided into the experimental group ( n=22 ) and the control group (n=22). They were treated with bleomycin 5 mg or pingyangmycin 4-8 mg injection under suspension microlaryngoscopy in the hemangioma, respectively. If the treatments were not curative, repeated one more times in intermittent 15 d, but not more than 3 times. Therapeutic effect and adverse effect were recorded and analyzed. Results The total effective rate (95. 4%)in the experimental group was significantly better than that (59. 1%) in the control group (P<0. 05),and side reaction in two groups showed no significant variation. Conclusion Pingyangmycin local injection for treating laryngopharyngeal and laryngeal hemangioma is effective, less adverse reaction.

A female patient with a dark red mass in the of preauricular area for over 3 months was hospitalized. Enhanced CT scan and ultrasonography showed that the mass had clear boundaries and was rich in blood supply. The patient was misdiagnosed as preauricular hemangioma, then the mass was removed as a benign tumor and found irrelevant to parot, SMA(+), Vim(+), S-100(+), indicating myoepithelial carcinoma. So a radical excision was performed to get negative incised margin. The patient didn't undergo postoperative chemotherapy but demonstrated no evidence of recurrence over a 12-month follow-up.

Conclusion HBO can improve the cognitive function in patients with LA.

ObjectiveTo search detecting urine transforming growth factor-β1(TGF-β1) of type 2 diabetes mellitus(DM) in diagnosing early diabetic nephropathy in old patients.MethodsTGF-β1,microalbumin,microglobulin α1 and microglobulin β2 in urine from 53 cases of old type 2 diabetics and 27 cases of normal controls were detected.ResultsTGF-β1 was(21.2±7.32) ng/mmolCr in diabetics whose urine albumin were normal and was(58.79±25.93) ng/mmolCr in diabetics whose urine microalbumin was abnormal(P<0.01).Both were significantly higher than that of the normal control which was(7.79±3.58) ng/mmolCr(P<0.01).TGF-β1 was direct remarkably correlative with microablumin(r=0.5415),microglobulin α1(r=0.6282) and microglobulin β2(r=0.3248)(P<0.01 respectively),but was nothing with glycohemoglobin(r=0.2304,P>0.05).ConclusionTGF-β1 detection may be used as a sensitive and reliable guideline to diagnose early diabetic nephropathy in old diabetics.

Objective:To observe the effect of stereotactic aspiration combined with corresponding drug therapy in the treatment of cerebral hemorrhage induced by different drugs. Methods:Totally 66 patients with hemorrhage induced by antithrombotic drugs were randomly divided into the control group and the treatment group with 33 cases in each. The control group was given corresponding drug therapy according to the pathogenesis of cerebral hemorrhage, and the treatment group was treated by stereotactic hematoma aspiration additionally. Daily life ability, NIHSS and prognosis improvement were compared between the two groups before and after the treat-ment. Results:After the treatment, NIHSS of the treatment group was ( 10. 17 ± 2. 97 ) and Barthel index score was ( 59. 97 ± 12. 10), which were both better than those of the control group (P<0. 05). The prognosis of the treatment group was also better than that of the control group (P<0. 05). There was no severe adverse drug reaction in the two groups. Conclusion:For different drug in-duced cerebral hemorrhage, corresponding drug therapy should be carried out, and combining with stereotactic hematoma aspiration, the therapeutic regimen can effectively improve neurological deficits and activities of daily living of the patients, and then improve the prognosis of the patients with promising safety.

Objective To evaluate the safety and feasibility of laparoscopy in combination with fast track colorectal surgery (FTCS) in the treatment of colorectal cancer in the elderly.Methods A total of 123 patients were randomly divided into 3 groups:the laparoscopy plus FTCS group (n=41),the laparoscopy group (n=41) and the laparotomy group (n=41).Parameters for measuring surgical quality,recovery and postoperative complications were analysed.Results No significant differences were found in age,gender,tumor location,anesthesia ASA classification,American Joint Committee on Cancer (AJCC) Tumor Node Metastasis (TNM) staging,Eastern Cooperative Oncology Group (ECOG) score or complications between the three groups (P＞0.05 for all).There were no differences in blood loss,operative time,time required to resume defecation or number of lymph nodes dissected between the laparoscopy plus FTCS group and the laparoscopy or laparotomy group (P＞0.05 for all),but time taken to initiate postoperative ambulation,time taken to resume flatulence,time taken to start intake of liquid food and length of hospital stay were shorter in the laparoscopy plus FTCS group than in the other groups (P ＜ 0.05 for all).The incidence of postoperative complications was 12.2％ or 5/41 in the laparoscopy plus FTCS group,which was lower than in the laparoscopy group (34.1％ or 14/41) and in the laparotomy group (68.3％ or 28/41) (x2 =5.549 and 28.826,P=0.018 and 0.01,respectively),a statistically significant difference was also found between the latter two groups (x2 =9.567,P =0.002).Conclusions Laparoscopy in combination with FTCS is safe and effective in the treatment of colorectal cancer in the elderly.

BACKGROUND: There are currently many cryopreservation methods for the aminotic membrane, which have varying effects on the ultrastructure and biological activity of amniotic membrane, but on no one is effective.
OBJECTIVE: To compare the effects of different cryopreservation methods on the ultrastructure and viability of aminotic membrane and to seek the ideal cryopreservation method.
METHODS: Aminotic membrane separated from the fresh placenta was preserved respectively with deep-frozen cryopreservation and vitrification, and everyway was run for 3 and 6 months. Fresh aminotic membrane was used as control. The ultrastructure of aminotic membrane was observed by transmission electron microscopy, and the viability of aminotic membrane was assessed by microcomputer analysis system for biological oxygen consumption, and immunohistochemical staining combined with image analysis system was used for lactate dehydrogenase activity.
RESULTS AND CONCLUSION:After 3 and 6 months of crypreservation, the damage to the ultrastructure of aminotic membrane by vitreous cryopreservation was slighter than that of amniotic membrane cryopreserved at-80℃. Compared with the fresh aminotic membrane, the gray value of lactate dehydrogenase and partial pressure of oxygen were significantly decreased in the cryopreserved aminotic membrane by deep-frozen cryopreservation at 3 and 6 months (P < 0.05) and by vitreous cryopreservation at 6 months (P < 0.05), but there was no statisticaly significant difference in the change rate of oxygen partial pressure and the gray value of lactate dehydrogenase between the fresh aminotic membrane and the cryopreserved aminotic membrane by vitreous cryopreservation at 3 months. The present study led to the conclusion that vitreous cryopreservation protocol alows to not only maintain the integrity of AM, but also to preserve the viability of the cels. So the vitreous cryopreservation is superior to the deep-frozen cryopreservation for cryopreservation of aminotic membrane.

BACKGROUND: Enophthalmos deformity is the most common complication caused by orbital blow-out fractures, and others are diplopia and worsening of visual acuity. Since the therapeutic result of orbital blow-out is not satisfactory and many complications exist after operation, it is still a dispute to select implantation materials and therapeutic regimens.OBJECTIVE: To observe the therapeutic effect and assess the improvement of visual function by surgical reconstruction with porous high-density polyethylene (Medpor) for the correction of enophthalmos deformity caused by orbital blow-out fractures.DESIGN: A pre-and postoperative controlled study.SETTING: Beauty Center for Trauma Repair,Plastic Surgery Hospital,Peking Union Medical College, Chinese Academy of Medical Science .PARTICIPANTS: Totally 56 patients with orbital blow-out fractures who had enophthalmos deformity caused by fists or traffic accidents, treated at Beauty Center for Trauma Repair,Plastic Surgery Hospital, Peking Union Medical College, Chinese Academy of Medical Science, were selected in this study from December 1996 to March 2004. Final diagnosis were made with case history, X-ray film, two-demensional and three-dimensional CT before operation. 24 cases were accompanied with other areas fractures such as zygoma and nasal bone, 34 cases with diplopia, 35 cases with visual acuity worsening after injured.METHODS: ①Material implantation: Exposure of the orbital floor, inferior and medial walls could be performed through a 2 mm inferior subciliary incision of 3 cm long. To approach the orbital rim via a dissection plane anterior to the orbital septum, sub-periosteal dissection was then performed over the orbital rim, and along the orbital floor to the orbital apex. Mobilized the soft tissue from the bone throughout the entire area of fractures and re-position it to its proper position. Took Medpor (Type 6331) sheets as the implantation materials, trimmed Medpor sheets according to the radian and anatomic form, and 2 mm larger than the defect rim was needed.If other operations were needed during the operation, they could be done.Mannitol and dexamethasone should be used just postoperatively to decrease edema of the orbital contents and reduce inner orbital excessive pressure. ②Functional evaluation standard: Diplopia: completely disappear meant recovered, less diplopia residual meant improvement, no improvement meant inefficacy. Enophthalmos: marked improvement meant the degree of enophthalmos stabilizated at below 2 mm, less improvement meant stabilizated at above 2 mm.MAIN OUTCOME MEASURES: ①Improvement of enophthalmos; ②Improvement of diplopia ; ③Improvement of visual acuity.RESULTS: ①All 56 cases of enophthalmos deformities caused by orbital blow-out fractures improved greatly. ② Of all the 34 patients with diplopia, 27 recovered. ③ 9 patients' visual acuity of 35 improved with different degrees. No diplopia or visual acuity worsening occurred. With a follow-up ranging from 2 months to 5 years, the degree of enophthalmos stabilizated at below 2 mm, and no relapse and other complications occurred.CONCLUTION: Medpor has such advantages as better histocompatibility,fewer complications and better visual function improvement, so it is the preferred implantation material for correcting enophthalmos deformity caused by orbital blow-out fractures.
