? AIM: To explore the curative effect of dacryocystorhinostomy under endoscopy with mitomycin for the treatment of chronic dacryocystitis.?METHODS: Totally 73 cases ( 78 eyes ) with chronic dacryocystitis were treated with dacryocystorhinostomy under endoscopy with mitomycin and followed up for 6-12mo.?RESULTS: In the 73 patients, 66 cases with 70 eyes (90%) were cured, 2 cases with 3 eyes (4%) improved, 5 cases with 5 eyes ( 6%) not changed. In the recurrent 5 eyes, 2 eyes were treated under endoscopy to remove granulation, enlarge the opening, then anesthetic tube was placed after cotton sheet with 0. 4g/L mitomycin was put on the incision for 5min. The rest 3 eyes were treated in superior hospital with laser, and all were successful. There was no severe complication observed.?CONCLUSION:Dacryocystorhinostomy under endoscopy with mitomycin for chronic dacryocystitis is effective.

OBJECTIVETo improve the clinician's ability for emergency treatment of priapism.

METHODSBoth cases received 2 mg to 8 mg of metaraminol injection at the root of cavernous body, and perfusion of heparinized saline at glans and root of cavernous body of the penis by contrecoup, but they had not good response to the above therapy. At last surgery was performed.

RESULTSTotal penectomy was performed for both cases. One case was diagnosed of penile sarcoma, and another was metastatic transitional cell carcinoma.

CONCLUSIONPriapism due to neoplasma is infrequent, it should not be misdiagnosed in case of emergency.

OBJECTIVETo discuss the diagnosis and treatment of penile carcinoma in circumcised men.

METHODSWe reviewed 17 cases of penile carcinoma detected 1 month to 16 years after circumcision performed in our hospital from January, 1997 to December, 2004.

RESULTSOf the total number, 11 cases were diagnosed as penile carcinoma 1 - 12 months and the others 3 - 16 years after the circumcision. Sixteen of them were treated by partial penectomy, anti 1 first by extensive circumcision and later by partial and total penectomy successively after recurrence. Cloquet nodes biopsy showed 16 cases to be pathologically well-differentiated and I case moderately differentiated penile squamous carcinoma. One died of extensive metastasis, but the other 16 remained disease-free survivals.

CONCLUSIONCircumcised adult men, especially those over 40 years of age, are likely to develop penile carcinoma. Patients with inflammation, plaque or ulcer in the prepuce should be checked by pathological biopsy and followed up closely. For Stage-I penile squamous carcinoma, partial penectomy is shown to be an effective therapeutic option, and Cloquet's nodes biopsy is necessary for all patients.

OBJECTIVETo compare the chemical differences in 4 commercial specifications of Scutellaria Radix, research the affection of decayed central xylem part on the crude drug's chemical composition and provide scientific data for production, processing, sale and clinical applications of Scutellariae Radix.

METHODMacroscopical identification method was used for observation of different specifications of Scutellariae Radix, including Qinwang, Tiaoqin both in 1st class and 2nd class and inferior samples. HPLC fingerprint method was used to analyze chemically the decayed central xylem part and non-decayed part as well as complete sample, and the results were described by the relative peak area.

RESULTThe morphological characteristics of 4 specifications are greatly different from one another mainly in root diameters, root lengths and the proportions of decayed central xylem part in the root, and so the authors classified Qinwang and Tiaoqin in 1st class as Kuqin for all samples of them which have decayed central xylem; and classified Tiaoqin in 2nd class and the inferior samples as Ziqin, for having little decayed central xylem. The 4 specifications collected from the same producing area have similar HPLC fingerprint profile to one another, while they are different in relative peak area. The peak area ratios of aglycone to their glucuronide (baicalein/baicalin, wogonin/wogonoside, oroxylin A/oroxylin A-7-O-glucuronide) from Kuqin were significantly higher than those of Ziqin. The total area of the peaks in HPLC fingerprint chromatographs of decayed central xylem part were quite lower than that of non-decayed part, whereas peak areas of the characteristic peaks and the 3 peak area ratios of decayed central xylem were significantly higher than those of non-decayed part which could be used as characteristic parameters to distinguish Kuqin and Ziqin.

CONCLUSIONFour commercial specifications of Scutellariae Radix can be classified as Kuqin and Ziqin respectively according to morphological characteristics and the proportions of decayed central xylem part in the root. The chemical characteristics of Kuqin and Ziqin are different from each other, so it's worth clarifying the similarities and differences of Kuqin and Ziqin in future. The result in this research can be used as references for identification and quality control of Scutellariae Radix specifications, and investigation on effective components of Kuqin and Ziqin.

OBJECTIVETo explore clinical efficacy of hip replacement for hip-joint diseases with Parkinson disease.

METHODSFrom December 2011 to December 2016, 18 patients with hip-joint diseases with Parkinson disease treated by hip replacement, including 8 males and 10 females aged from 59 to 87 years old with an average of 71 years old. Among them, 3 cases were developmental dysplasia of hip, 3 cases were femoral head necrosis and 12 cases were femoral neck fracture. All patients manifested with obvious pain and limitation of stepping ability. Postoperative complications were observed and Harris score were used to compare hip joint function after operation.

RESULTSThe incision were healed well, and pain were alleviated or disappeared, and hip joint function were improved. Eighteen patients were followed up from 1 to 3 years with an average of 2.3 years. At the latest follow up, 14 cases recovered freedom-walk, 2 cases could walk with walking stick, 1 case could walk with walking aid and 1 case was died. Among 18 patients, 2 cases were occurred dislocation, and 1 case were died for cardiac disease at 3 months after operation. Four patients were occurred slight pain. There were significant differences in Harris scores among preoperative (41.7±1.4), 6 months after operation(80.1±5.4) and the final follow-up (83.4±2.1), and 10 cases got excellent result, 4 good, 1 fair and 2 poor.

CONCLUSIONSApplication of hip replacement for hip-joint diseases with Parkinson disease is a safe and effective clinical therapy, and has advantages of less complications and rapid recovery of hip joint function.

OBJECTIVEOne of the important reasons for male infertility is asthenozoospermia, for which there is no specific cure for the time being. The authors explored the clinical effect of L-carnitine for infertile males with asthenozoospermia.

METHODSA total of 135 patients with asthenozoospermia were randomly divided into Groups A (n = 68) and B (n = 67), the former treated with L-carnitine (2 g/d) and vitamin E, while the latter with vitamin E only, both for 3 months. All the patients received semen analyses before and after the treatment, and were observed for adverse effects. The pregnancy rates of their wives were recorded.

RESULTSGroup A showed a significantly increased percentage of forward motile sperm after the treatment (45.4% +/- 11.1%) as compared with pretreatment (28.6% +/- 9.2%) (P < 0.01), but no statistically significant differences were found in sperm density and the percentage of the sperm of normal morphology (P > 0.05). The rate of pregnancy was significantly higher in Group A (31.1%) than in B (3.8%) after the treatment (P < 0.01). No adverse events were found during the treatment.

CONCLUSIONL-carnitine, capable of significantly improving sperm motility and raising the rate of pregnancy, is a safe and effective therapeutic option for asthenozoospermia.

OBJECTIVETo retrospective analysis the mid-term follow-up effect of hip joint replacement in elderly patients with failure of intertrochanteric fractures of the hip joint internal fixation.

METHODSFrom December 2008 to December 2011, 32 elderly patients underwent arthroplasty after intertrochanteric fracture fixation failure, of which, 4 death cases were excluded from the study, and the remaining 28 cases were in the study group. The age of patients ranged from 69 to 83 years old with a mean of 75 years old. The time from the internal fixation to the hip replacement were 8 to 72 months. Among them, 6 patients were Evans I type, 11 patients were Evans II type, 9 patients were Evans III type, and 2 patients were Evans IV type. Nine cases showed fracture of the lateral plate before operation, while 15 cases were femoral head screw cut-out and 4 cases were screw loosening. Harris score was used to compare the changes of hip function before operation with the final follow-up. Imaging results(X-ray) and erythrocyte sedimentation rate(ESR) were performed during the follow-up.

RESULTSAll patients were followed up from 4 to 7 years with an average of 5.3 years. Pain was significantly reduced or disappeared in patients compared with pre-operation. And hip function was significantly improved. Two cases had moderate pain after the physical activity and 4 cases had mild pain after the physical activity. At the final follow-up, 19 patients resumed free walking, 8 patients required walking with walking sticks, and 1 patient needed walking aid. The Harris scores improved from preoperative 34.9±2.4 to 83.4±5.7 at the final follow-up, among them, 15 cases were classified as excellent, 10 as good, 2 as fair, and 1 as poor. X-ray examination showed no prosthesis loosening and sinking fracture.

CONCLUSIONSSalvage THA surgery could improve the hip function and the quality of life for old patients with intertrochanteric fracture fixation failure, and the middle-term follow-up results support that.
