OBJECTIVE: To study a surgical and repairing method for defects after the resection of basal cell carcinoma of external nose. METHOD: There are 26 cases of basal cell carcinoma that tumors have been resected completely after operation. For defect repairing in those 26 cases, 2 cases adopt direct suture method; 2 cases use skin graft repairing methods; 18 cases employ naselabial skin flap repairing method; 4 cases choose forehead pedicle skin flap repairing methods. RESULT: the wound of all the 26 cases was primary healed. Additionally, skin flap and skin graft were all survived. Follow-up studied in patients 1 to 3 years after the surgery showed that the local scar was not obvious and no tumor recurred or transferred. CONCLUSION Different surgical and repairing methods are performed to obtain a satisfactory results based on the area of defect and its location in nose. Naselabial skin flap is especially an ideal method to repair defects.

OBJECTIVETo compare robot-assisted laparoscopic radical prostatectomy (RALRP) with laparoscopic radical prostatectomy (LRP) in the treatment of prostate cancer and investigate the clinical application value of RLRP.

METHODSWe retrospectively analyzed 70 cases of prostate cancer treated by RALRP and another 32 cases treated by LRP. We compared the operation time, intraoperative blood loss and transfusion, catheter-indwelling time, postoperative hospital stay, incisal margin positive rate, biochemical recurrence, and normal postoperative urinary continence and penile erectile function between the two groups of patients.

RESULTSAll the operations were successfully accomplished. RALRP exhibited a significant superiority over LRP in intraoperative blood loss and transfusion, catheter-indwelling time, and postoperative hospital stay, urinary continence and erectile function (P < 0.05).

CONCLUSIONRobot-assisted laparoscopic radical prostatectomy, with its advantages of few postoperative complications and well-preserved urinary continence and penile erectile function, is an effective, safe and minimally invasive surgical option for prostate cancer.

OBJECTIVETo assess the safety of hyperbaric oxygen in the treatment of radiation-induced hemorrhagic cystitis in patients with prostate cancer, and to investigate its effect on the growth of indolent prostate cancer in vivo.

METHODSThirty severe combined-immunodeficient mice received subcutaneous injection of human prostate cancer LNCaP cells. Then they were randomized to an experimental and a control group and exposed to 20 sessions of hyperbaric oxygen and normobaric air, respectively, followed by a 4-week observation on the growth of the transplanted tumors and analyses of their histopathological features at 28 days, including the volume, microvessel density (CD34), apoptosis markers (p53 and p27 proteins) and the proliferation index (Ki-67) of the LNCaP tumors.

RESULTSOn the 28th day after tumor vaccination, the tumor volume was (120 +/- 7.9) mm3 in the HBO and (122 +/- 8.2) mm3 in the control group; the microvessel density and the expressions of Ki-67, p53 and p27 were 39.3 +/- 5.2, (78.1 +/- 7.6)%, (40.4 +/- 6.2)% and (63.7 +/- 5.1)% in the former, and 36.2 +/- 4.9, (75.3 +/- 8.4)%, (44.2 +/- 5.7)% and (61.5 +/- 5.5)% in the latter. There were no significant differences in all the indexes above between the two groups (P > 0.05).

CONCLUSIONHyperbaric oxygen did not promote the growth of indolent prostate cancer in the murine model, nor did it have any significant effect on the new vessels.

Objective:To investigate the characteristics of atelectasis and its relationship with the degree of diaphragm inhibition in elderly patients with artificial pneumoperitoneum under general anesthesia.Methods:Patients of both sexes, aged 20-80 yr, of American society of Anesthesiologists physical status Ⅰor Ⅱ, with body mass index of 20-29 kg/m 2, scheduled for elective laparoscopic cholecystectomy under general anesthesia, were divided into 2 groups ( n=20 each) according to age: young and middle-aged group and elderly group.Total intravenous anesthesia was applied and intraoperative pressure of artificial pneumoperitoneum was set at 10 mmHg.Before anesthesia, at 5 min of mechanical ventilation, at 5 min of artificial pneumoperitoneum, at 20 min of artificial pneumoperitoneum, at 5 min after the end of artificial pneumoperitoneum and at 15 min after extubation, diaphragmatic excursion (DE) was measured at the right diaphragm point using M-mode ultrasound.The minimal DE was recorded and the maximum degree of diaphragm inhibition was calculated.B-mode was used to assess the lung ultrasound images at the upper bedside lung ultrasound in emergency (BLUE) point, the lower BLUE point and the diaphragm point, and the cumulative scores before anesthesia and perioperative maximum cumulative scores of lung ultrasound score (LUS) were recorded. Results:Compared with the young and middle-aged group, the maximum cumulative scores of LUS were significantly increased, the degree of DE before anesthesia, the perioperative maximum degree of diaphragm inhibition were increased ( P<0.05), and no significant change was found in LUS cumulative scores in elderly group ( P>0.05). Conclusion:The degree of atelectasis is more serious in the elderly patients with artificial pneumoperitoneum under general anesthesia, and the mechamism may be related to the increased degree of diaphragm inhibition.

OBJECTIVETo study the relationship between the testis volume and types of spermatogenic cells derived from testicular biopsy in patients with azoospermia or cryptozoospermia.

METHODSWe collected testicular pathological biopsies from 492 infertile patients with azoospermia or cryptozoospermia reported in our hospital, classified them according to the testicular histological classification methods in WHO Manual for Standardized Investigation, Diagnosis and Management of the Infertile Male, and analyzed the relationship of the testis volume with the results of semen analyses and testicular histology.

RESULTSOf the 492 cases, 90.5% (445/492) were azoospermia and 9.5% (47/492) cryptozoospermia; mature spermatozoa were present in the seminiferous tubules in 17.9% (88/492) but absent in 42.9% (211/492), and Sertoli cell-only syndrome indicated in 39.2% (193/492); the testis volume was < or = 10 ml in 38.6% (190/492) and < or = 5 ml in 7.9% (39/492). Cryptozoospermia was detected in 14.8% (13/88) of those with mature spermatozoa in the seminiferous tubules, in 11.4% (24/211) of those without, and in 5.2% (10/193) of those with Sertoli cell-only syndrome, with a significantly lower rate in the latter group than in the former two (P < 0.05).

CONCLUSIONSpermatogenesis of the testis may be focal and difficult to be completely reflected by a single testicular biopsy, and it may exist even if the testis volume is significantly below the reference value. The indications for testicular biopsy should not be improperly expanded. The WHO testicular histological classification methods have provided a convenient and effective guidance for further clinical examinations and establishment of a protocol.

OBJECTIVETo study the incidence of the chromosome abnormalities and Y chromosome microdeletions in Chinese patients with azoospermia and cryptozoospermia.

METHODSConventional chromosomal karyotyping was used to analyze the chromosome abnormalities. Genomic DNA was extracted from peripheral blood samples and multiplex polymerase chain reactions (PCR) analyses were performed using specific primers to confirm the presence or absence of Y chromosome microdeletions. A total of 997 patients with azoospermia and cryptozoospermia were enrolled in the study.

RESULTSThe incidence of chromosome abnormalities in the patient with azoospermia and cryptozoospermia was 28.4%. The major abnormal karyotypes included 47,XXY, 46,XY (Y>G), 46,XX, chimera and translocations. The incidence of the Y chromosome microdeletions was 17.4%. They were mainly found in the karyotypes of 46,XY and 46,XY (Y>G).

CONCLUSIONChromosome abnormalities were the most common hereditary causes of the patients with azoospermia and cryptozoospermia. The incidence of Y chromosome microdeletion was higher in the patients with karyotype of 46,XY and 46,XY (Y>G). Therefore, detection of the AZF microdeletion in these patients is helpful to determine the etiology and avoid the unnecessary treatment and vertical transmission of the genetic defects.
