Objective To discuss the feasibility of percutaneous nephrolithotomy (PCNL) for treating upper urinary calculi under local anesthesia.Methods One thousand three hundred and sixty-three patients who suffered with upper urinary calculi were treated with PCNL, the puncture and tracts were created using local anesthesia and guided through ultrasound.Of the 1363 patients, 475 patients had complicated renal caluli, 520 patients had kidney pelvic calculi and 368 had upper uretere calculi.Results All of the patients successfully received PCNL under the local anesthesia.Of the 1363 patients five tracts were used in two patients, four tracts were used in four patients, three tracts were used in nine patients, double tracts were used in 25 patents and one tract was used in the remaining patients.The stone-free rate was 96.0% in the kidney pelvic calculi patients, 100.0% in the upper uretere calculi patients, and 90.1% in the complicated renal caluli patients.90.0% patients were find well throught the operation, 10.0% patients find a little pain and solved by another more 5 - 10 ml lidocaine local injection or 50 - 75 mg pethidine hydrochloride intramuscular injection.No case stop operation because of pain or position changed.All without any severe complications such as damaged of liver, spleen, thorax and intestine.Conclusion The PCNL handled under local anesthesia was simple safe and effective, deserved clinical popularizing use.

Objective To observe the clinical effect and comfortable degree of the mode of super hair removal. Methods The mode of super hair removal was used to depilate the hair nearby the hair line, cheeks, upper lip, beard, ventrum, areola of breast, axillary cavity, extremities, bikini area and so on. The total number of sites was 1 000. Some sites that were especially susceptible to pain, for example, upper lip and buccal region, were smeared with compound lidocaine cream for 1 hour at least before treatment. Results Hairs in the areas of extremities, ventrum, back and axillary cavity generally needed 4 to 5 times to eradicate, and the patients had no evident discomfortableness; hairs near to the upper lip and lower mandible generally needed 5 to 7 times to reach the effect which the patient was content, and anesthetics was indispensable, or the patients would present discomfortableness. Conclusions The mode of super hair removal is more effective, quicker and more comfortable in comparison with conventional methods. Therefore, it deserves to be spread.

Objective To observe the effects of Niupo Zhibao pellet, a compound traditional Chinese herbal medicine,on helper T cell(Th cell)expression in rats with endotoxin-induced rapid pulmonary fibrosis (RPF). Methods Two hundred and twenty-four Wistar rats were randomly divided into four groups:normal control,model,dexamethasone(DXM)and Niupo Zhibao pellet(NW)groups(each n=56). By using endotoxin three-hit regimen,the RPF model was established. Three days before and 7 days after the establishment of models in NW group,they were administered with the pellet by intragastric feeding,50 mg/100 g of distilled water twice a day,a total of 10 days medication. Rats in DXM group received DXM intraperitoneal injection,3.0 mg/kg once a day for consecutive 7 days. Rats in normal control group were administered with the same volume of distilled water by intragastric administration. On 1,3,7,9,14,21,28 days after the administration,blood and bronchoalveolar lavage fluid(BALF)specimens were collected. The contents of γ-interferon(IFN-γ)and interleukin-4(IL-4) in the serum and BALF were investigated by enzyme-linked immunosorbent assays(ELISA). The lung tissue was stained by hematoxylin-eosin(HE)and Van Gieson respectively. Morphological changes in lung tissue were observed under light microscope. Results HE staining showed that the pulmonary interstitial tissues of rats in model group were thickened,there was a large amount of inflammatory exudates,and micro thrombi were seem in alveolar space. The pulmonary interstitial tissues in rats of DXM group were thickened too,but the inflammatory exudate in alveolar space was much less. Compared to rats in DXM group,the rats in NW group had slightly more inflammatory exudate and their pulmonary interstitial tissues were basically normal. Van Gieson staining showed that the expression of collagen fiber in model group was obvious,that of DXM group less than the former one but not significant,while that in the NW group was reduced markedly. ELISA assays demonstrated that the levels of IFN-γin BALF and serum in model group were increased significantly,those in DXM group were lowered to the minimum on the 7th day,raised to the levels before treatment on the 14th day,and gradually declined on the 21st day. In the NW group,the IFN-γwas consistently at a high level,and then gradually declined at a slow rate. After 7 days of drug administration,the IFN-γ levels in BALF and serum at various time points in NW group were obviously higher than those in model and DXM groups〔BALF(ng/L):140.47±4.22 vs. 149.23±8.35,90.67±6.65;serum(ng/L):140.47±4.15 vs. 100.43±11.05,99.35±7.85,P<0.05 or P<0.01〕. The levels of IL-4 in BALF and serum in each group increased significantly,reached to their maximum on the 7th day,and then gradually decreased. After the drug administration for 28 days,those levels in NW group were obviously lower than those in model and DXM group〔BALF(ng/L):6.60±1.05 vs. 7.20±1.25,8.55±1.05,serum(ng/L):6.75±1.05 vs. 7.21±1.25,8.25±1.15,P<0.05 or P<0.01〕. Conclusion Niupo Zhibao pellet can suppress inflammation,ameliorate injury of lungs and inhibit lung fibrosis by promoting IFN-γsecretion,restraining IL-4 secretion and adjusting the imbalance of Th cells.

BACKGROUND: A large amount of cell dies of apoptosis in secondary injury stage after spinal cord injury.OBJECTIVE: To probe into the influence of local intraspinal infusion with danshen injection on necrosis and apoptosis of spinal cell after acute spinal cord injury.DESIGN: Randomized controlled experiment was designed.SETTING: Clinical Medical Trial Center of People' s Hospital Affiliated to Yunyang Medical College.MATERIALS: Forty-four Chinese white rabbits of first grade were employed, aged varied from 4 to 5 months, of either sex, mass weighted varied from 2.0 to 2.5 kg.INTERVENTIONS: The experiment was performed in Clinical Medical Trial Center of People' s Hospital Affiliated to Yunyang Medical College from June 2002 to July 2003. Two groups were randomized, named danshen group and the control group, 22 rabbits for each. In both groups, modified Allen method was used to prepare the model of incomplete spinal cord injury. In danshen group, danshen injection was infused from subdural catheter for 4times at 0. 3 mL/kg per day of the total amount (once every 6 hours). In the control group, physiological saline of same dose was injected. The animals were sacrificed at the 8th, 24th and 72nd hours successively after injection for pathological and histomorphologic observation, peroxide dismutase and malondialdehyde determination and determination of positive cell count of B-cell lymphoma-2 (Bcl-2), the apoptosis-inhibition gene.MAIN OUTCOME MEASURES: Cell apoptotic index and cell apoptotic rate in the region of spinal cord injury.RESULTS: Forty-four rabbits entered result analysis for all. ① Results of cell apoptosis: Apoptotic index in danshen group was less remarkably than that in the control group(13.10 ± 1. 38, 20.39±2.96, 4.101, P ＜0.01); cell apoptotic rate was lower remarkably than the control group[ (9.67 ± 1.09)%,(14.68±2.81)%, t=4.072, P ＜0.01] and Bcl-2 expression was more than that in the control group[ (19. 12 ± 4.74) /mm2, ( 13.37 ± 3.68) /mm2,t = 2. 347, P ＜ 0.01 ]. ② POD content: The result in danshen group was higher thanthe control group[ (136.20 ± 13.64) NU/mL, (101.70 ± 15.24) NU/mL,t = 4. 132, P ＜ 0.01 ]. ③ Malondialdehyde content: The result in danshen group was lower than the control group[ (1.27 ± 0. 22) nmol/mL,(2.54±0.69) nmol/mL, t=4.309, P ＜0.01] . ④Degeneration and necrosis of neuron and neural fiber: The result in danshen group was milder than the control group.CONCLUSION: After local infusion with danshen(Radix Salviae Miltiorrhizae), cell apoptosis was decreased in local spinal cord injury and cell necrosis was inhibited and alleviated after acute spinal cord injury.

OBJECTIVETo construct three-dimensional (3D) models of renal stones and perform percutaneous nephrolithotomy (PCNL) virtual surgery simulation. Methods CT images were obtained from 8 patients with renal stones. Images segmentation and reconstruction were performed using MIMICS 10.0 software to construct the 3D model of the renal stones, which provided the anatomical relationships between the kidney and the adjacent organs. The optimal PCNL virtual surgery simulation for each individual case was performed using FreeForm Modeling System on the basis of the 3D model.

RESULTSEight 3D models of renal stone were constructed. The 3D model of the renal stones represented the interrelationships of the stones, intrarenal vessel, and the collecting system with the adjacent anatomical structures. Individualized PCNL virtual surgery simulations including percutaneous puncture, dilatation and pneumatic lithotripsy were performed successfully in all the 8 3D models.

CONCLUSIONDigital 3D model of renal stone provides the reliable and comprehensive imaging information for surgical design, and PCNL virtual surgery simulation has important clinical significance to improve the stone clearance rate and reduce the surgical complications.

Objective:To explore a surgical method for patients with moderate to severe hypertrophy of the labia minora, obvious pigmentation, and bilateral asymmetry.Methods:From August 2016 to August 2018, we applied a combined wedge resection and marginal arc resection to 23 cases of labia minora hypertrophy.Results:There were no complications such as infection and hematoma, and the incision healed in one stage. The follow-up period was from 1 month to 6 months. The width of the labia minora did not exceed 1.5 cm, and the appearance was natural, beautiful and rejuvenated. The patients were satisfied.Conclusions:Layered wedge resection combined with edge arc resection of the labia minora has the advantages of natural youthful appearance, low secondary surgical repair rate, fewer postoperative complications, and high patient satisfaction. It is agood approach for the labia majora, especially the moderate to severe type. Patients with obvious pigmentation and bilateral asymmetry are an ideal candidates for this method.

Objective:To investigate the effect of modified alar reduction with external incision to correct alar hypertrophy.Methods:From January 2017 to January 2019, 16 patients(1 male and 15 females, aged 21 to 39 with alar hypertrophy were treated in the plastic surgery department of the Second Affiliated Hospital of Nanchang University. Modified alar reduction with external incision were applied. In order to rotate the free alar lobules, the incision was extended in nasal lobules to the vestibular floor and remove part of the vestibular tissue of the alar lobules during the operation. Then the free alar was moved into the nostril to make the alar junction shift inward and upward, and reposition the alar junction to correct the alar hypertrophy and the wide nasal base. Photos of patients in frontal, side, and basal view before operation, 1 month, 6 months after operation. Intercanthal distance (ICD)、interinter-alar width (IW)、nasal base width (BW) were measured. The ratios of IW, BW and ICD before operation, 1 month, and 6 months after operation, and the narrowing rate of IW and BW at 1 month and 6 months after operation were summarized. The incision scar was evaluated with reference to the Vancouver Scar Scale. Normally distributed variables were compared using an paired t test. Nonparametric continuous variables were compared using Wilcoxon rank sum test. When P<0.05, the difference is considered statistically significant. Results:Sixteen patients were followed up for 6 to 12 months, averaged of 8 months. The IW/ICD of 16 patients at preoperation, after operation 1 month and 6 months were 1.160±0.080, 1.049±0.047 (0.110±0.049 decrease than before operation) and 1.038±0.047 (0.120±0.049 decrease than before operation). The differences were statistically significant ( P<0.05). The IW constriction rates were 9.3% at 1 month after operation and 10.2% at 6 months after operation. BW/ICD at preoperation, after operation 1 month and 6 months were 1.035±0.047, 0.960±0.039(0.072±0.019 smaller than preoperation), and 0.950±0.034(0.079±0.020 smaller than preoperation). Compared with preoperative data, the difference was statistically significant ( P<0.05). The BW reduction rates were 7.0% at 1 month after operation and 7.6% at 6 months after operation. The Vancouver Scar Scale score was 3(2.25, 3) at 1 month after operation, 1(0.25, 1) at 3 months after operation and 1(0, 1) at 6 months after operation. The differences were statistically significant ( P<0.05). There was a statistically significant difference between 3 months after surgery and 1 month after surgery ( Z=-3.472, P=0.001). There was no statistically significant difference between 6 months after surgery and 3 months after surgery ( Z=-1.414, P=0.157). All patients had no significant postoperative complications such as incision infection, asymmetry of nasal alae, obstruction of nasal ventilation, etc. Postoperative alar and nasal base profiles were significantly improved. Conclusions:Modified alar reduction with external incision can effectively treat alar hypertrophy without obvious postoperative complications. It is a good operation to correct alar hypertrophy.

Lipoma is the most common superficial benign tumor in clinical practice. Generally, lipoma is small in size. Giant lipoma is not common, and giant lipoma in tendon sheath is rare. We reports a case of axillary subcutaneous lipoma and giant lipoma in the tendon sheath. The preoperative diagnosis was a surface lipoma for the lack of clinical experience. Only color Doppler ultrasound is performed in the outpatient clinic. The preoperative examination was not sufficient, so the difficulties of the surgery was increased. We share the process for the clinician.
