Purpose:To improve the accurate diagnosis rate for renal angiomyolipoma (RAL) before operation.Methods:Data ofthe imaging and pathological characteristics of 54 cases of patients with renal angiomyolipoma that proved by surgery pathology were analyzed retrospectively.Results:Intravenos pyelography (IVP) did not depict any specific imaging for RAL. Selective renal arteriography (SRA), Ultrasonography(US) and computerized tomography (CT) depicted specific characteristics for RAL. But it was difficult to differ malignant changes from benign ones before surgery.Conclusions:It is widely accepted that the Ultrasonography, Computerized tomography is the best method of imaging examination. When necessary it is helpful to use selective renal arteriography.

OBJECTIVETo investigate the clinical efficacy and safety of photon therapy for benign prostate hyperplasia (BPH).

METHODSThirty patients with severe BPH received brachytherapy of prostate photon treatment system irradiation for one month, with the active area of the applicator located in the rectum, and at a dosage of 726-810 cGy. International prostate symptom score (IPSS), quality of life (QOL), volume of prostate gland, maximum flow rate (Qmax), and residual urine were evaluated before and after the treatment.

RESULTSAfter one-month treatment, 18 cases remarkably improved, 9 slightly improved and 3 had no response. There was significant improvement in IPSS, QOL, volume of prostate gland, Qmax and residual urine (P<0.01, except Qmax P = 0.038).

CONCLUSIONProstate photon treatment system can be used as a safe, effective, micro-invasive, convenient and economical therapy for severe BPH, especially applicable to older and weaker patients.

Objective:To investigate the clinical efficacy of a new 3D printed guide plate in the minimally invasive treatment of fresh closed Achilles tendon rupture.Methods:From January 2019 to January 2020, 14 fresh closed Achilles tendon ruptures were treated by minimally invasive surgery at Department of Foot and Ankle Surgery, Xuzhou Renci Hospital. There were 13 males and one female, with an average age of 39.1 years (from 18 to 63 years). The rupture of the Achilles tendon body, 3 cm in length on average, was located 2 to 6 cm above the attachment of the calcaneal tuberosity. The ruptured Achilles tendon was repaired by suture with the aid of the new 3D printed guide plate. After operation, in cooperation of the Rehabilitation Department, we performed rehabilitation exercise under the guidance of the concept of Enhanced Recovery After Surgery (ERAS). The length of incision, operation time, intraoperative blood loss, ankle function at the last follow-up and follow-up complications were recorded.Results:In this cohort, incision length averaged 2.5 cm (from 2.0 to 3.5 cm), operation time 45 min (from 30 to 60 min), and intraoperative blood loss 15 mL (from 10 to 20 mL). The 14 patients were followed up for 13 to 16 months (average, 14 months) after operation. In one patient, the epidermis at the incision edge became black and necrotic, which was healed after dressing change. Follow-ups observed no such complications as suture rejection, sural nerve injury, or Achilles tendon re-rupture. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores at the last follow-up averaged 98 points (from 93 to 99 points), yielding 13 excellent cases and one good case; according to the Arner-Lindholm evaluation, the efficacy was excellent in 12 cases, good in one and poor in one.Conclusion:The minimally invasive treatment of fresh closed Achilles tendon rupture with our new 3D printed guide plate has exhibited advantages of minimally invasive incision, limited complications, simple manipulation, good functional recovery of the ankle joint and strong reproducibility of surgical operations.

Objective:To summarise the experience in use of sural neurouascular flap in repair of the soft tissue defects of foot and ankle, and explore the methods in promoting the survival and appearance of the flap.Methods:Data of 10 patients who underwent sural neurocutaneous flap surgery for repairing soft tissue defects in the foot and ankle in the Department of Foot and Ankle of Xuzhou Renci Hospital from October 2019 to June 2020 were retrospectively analysed. Among the 10 patients, 8 were males and 2 were females, and the age ranged from 18 to 54 years old, with an average age of 42.5 years old; Causes of injury: 8 patients injured by traffic accident and 2 by incision necrosis after calcaneal fracture operation. The areas of soft tissue defect were 4.0 cm×6.0 cm-16.0 cm×10.0 cm. Sural neurouascular flap was used for the defect repairs. Method of optimisation: ①The small saphenous vein in the flap was separated and retained in the limb to optimise the venous circulation. ②Freed peroneal perforator vessels that entered the pedicle, and made the point where the vessels entering the pedicle as the rotation point. The pedicle contained the sural neurovascular bundle, the main trunk of the small saphenous vein and the fascia tissue, with a width about 2.0 cm. It not only increased the blood supply of the flaps, but also a good appearance of the pedicle. ③ The torsion of the pedicle was covered by an arc-shaped flap and transferred through an open channel to prevent compression. ④The donor site was covered with relay flap. According to the location of the donor site, a proximal peroneal artery perforator flap or medial and lateral sural artery perforator flap was selected. ⑤Sural nerve was anastomosed with the peripheral sensory nerve in some cases. The survival of the flap, Maryland Foot Function Score and British Medical Research Council (BMRC) sensory function evaluation were investigated in the follow-up to evaluate the functional recovery of the flap and limb.Results:All the 10 patients received the follow-up for 6 to 12 months, with an average of 8.5 months. The donor and recipient flaps survived completely with good appearance in lower limb, good soft texture, good elasticity and wear resistance. The sensation of the flap with nerve anastomosis in 3 cases was evaluated according to BMRC, and they achieved sensation recovery up to level of S 3 or above. The patients had great satisfactions. At the last follow-up, the curative efficacy was evaluated according to the Maryland scoring system. It ranged from 85 to 98 points, with an average of 91.6 point, 8 patients in excellent and 2 in good. Conclusion:Sural neurouascular flap can achieve a sufficient blood supply, a reasonable venous circulation and a high survival rate. The donor site was covered with relay flap to obtain a good appearance, and the anastomosed sensory nerve offered a good sensation. The function of foot and ankle recovered well, and the clinical effect was satisfactory.

Objective:To investigate the feasibility and safety of suprapubic bladder puncture and gland fixation in transurethral enucleation of the prostate.Methods:The clinical data of 15 patients with benign prostatic hyperplasia admitted to the First Affiliated Hospital of Guangxi Medical University from January 2020 to June 2020 were retrospectively analyzed. The age was (70.27±5.35) years old, preoperative serum prostate-specific antigen (PSA) level was (3.03±1.37) ng/ml, preoperative total prostate weight was 80.3(70.49, 96.78)g, preoperative postvoid residual urine volume(PVR)was 80 (55, 108)ml, and the maximum urine flow rate (Q max) was (6.13±2.25) ml/s. The international prostate symptom score(IPSS) was 25(22, 27), quality of life (QOL)score was 5(5, 6), international erectile function index-5 (IIEF-5) score was (15.38±5.10). All 15 patients underwent conventional transurethral plasma enucleation of prostate by using the three-lobe method, and the enucleated gland was pushed into the bladder completely. Then a laparoscopic pneumoperitoneum needle was used to perform suprappubic cystipuncture, and ureteral grasping forceps were inserted through the outer sheath. The forceps were used to fix the enencied gland. A rapid harvesting electric resection was performed in the broad space of the bladder, and the Ellick was rinsed to remove the tissue fragments. Surgical indicators and complications were recorded. The improvement of subjective score (IPSS, QOL, IIEF-5) and objective index (Q max, PVR) was compared between preoperative and postoperative. Results:All the 15 operations were completed successfully and there were no complications such as blood transfusion, capsule perforation, transurethral resection syndrome, bladder injury, bladder puncture site laceration and bleeding. The weight of resected prostate tissue was 44(40, 60)g, with blood loss (79.20±18.93)ml.The time of enucleation operation was (54.13±10.88)min, with harvest cutting time (14.67±2.50)min, evisceration efficiency (0.89±0.08)g/min, harvesting efficiency (3.26±0.36)g/min, bladder irrigation time (2.47±0.52) d. The time of indwelling catheter was (3.73±0.80)d.The postoperative hospital stay was (4.40±0.91) d. Temporary urinary incontinence occurred in 1 case after operation. All patients were followed up for 6 months after operation. The IPSS score was 3(2, 3), QOL score was 0(0, 1), IIEF-5 score was (20.12±2.30), Q maxwas (21.80±2.14) ml/s and PVR was 10(5, 15)ml, which were all significantly different compared with those before surgery ( P<0.05). The symptoms of the patients were significantly improved. Conclusions:Transurethral plasma enucleation of prostate combined with suprapubic bladder puncture and fixed gland is effective in the treatment of benign prostatic hyperplasia. The subjective symptoms and objective examination of patients have been significantly improved, and no adverse operation-related complications have occurred. It is a suitable method for enucleation of prostate in units which are not equipped with transurethral tissue planer.

Objective:To observe the effect of speech training based on mirror neuron theory on children with functional articulation disorder (FAD).Methods:Fifty children with FAD were randomly divided into a training group and a control group, each of 25. Both groups received 30 minutes of conventional speech training 5 times a week for 24 weeks, while the training group was additionally given 20 minutes of speech training based on mirror neuron theory simultaneously. Before and after the intervention, both groups were evaluated using the articulation speech ability assessment scale and the oral motor ability assessment scale.Results:Before the treatment, there were no significant differences between the 2 groups in any of the measurements. After the treatment, significant improvement was observed in all of the measurements for both groups, but at that point the training group′s articulation, motor ability of the lower jaw, tongue and lips were all significantly superior to the control group′s averages.Conclusions:Speech training based on mirror neuron theory can significantly improve the articulation, intelligibility and oral motor functioning of children with functional articulation disorder.

Objective:To investigate the efficacy of TiRobot navigation combined with ankle arthroscopy in the reduction and internal fixation of Hawkins type Ⅱ talus neck fracture.Methods:From January 2019 to September 2020, a total of 13 patients with Hawkins type Ⅱ talus neck fracture were admitted to Department of Foot and Ankle Surgery, Xuzhou Renci Hospital. They were 8 males and 5 females, with a mean age of 35.8 years (from 22 to 61 years). All fractures were reduced and fixated using TiRobot navigation combined with ankle arthroscopy. Time for fracture reduction assisted by intraoperative arthroscopy, time for internal fixation assisted by TiRobotic navigation, fracture union time and complications were recorded. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was used at the last follow-up to evaluate the functional outcomes.Results:All the operations were finished within 2 hour. The primary screw placement succeeded in all. The time for fracture reduction assisted by intraoperative arthroscopy averaged 52.8 min (from 43 to 66 min) and the time for internal fixation assisted by TiRobotic navigation 43.6 min (from 33 to 55 min). All the patients were followed up for an average 13.3 months(from 12 to 15 monhs). They obtained bony union within 3 months. One patient developed traumatic subtalar arthritis with mild pain and was treated conservatively. None of the patients had complications like incision infection or talus necrosis. The average AOFAS ankle-hindfoot score was 91.0 points (from 83 to 94 points) at the last follow-up.Conclusion:In the reduction and internal fixation of Hawkins type Ⅱ talus neck fracture, TiRobot navigation combined with ankle arthroscopy shows advantages of minimal invasion, accurate reduction and screw placement, and limited complications, leading to fine short-term functional outcomes.

Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Results:(1) Clinical characteristics of cirrhotic portal hypertension patients: of 820 cirrhotic portal hypertension patients, 271 cases were in compensated stage and 549 cases were in decompensated stage. Of the 271 cases in compensated stage, there were 183 maels and 88 females, aged (53±12)years. There were 185 Han people, 85 Hui people and 1 case of other ethic group. The etiological data of liver cirrhosis showed 211 cases of viral hepatitis B, 4 cases of alcoholic liver disease, 8 cases of viral hepatitis C, and 48 cases of other etiology. There were 235 cases of Child-Pugh grade A and 36 cases lack of data. Of the 549 cases in decompensated stage, there were 355 males and 194 females, aged (57±14) years. There were 373 Han people, 174 Hui people and 2 cases of other ethic group. The etiological data of liver cirrhosis showed 392 cases of viral hepatitis B, 33 cases of alcoholic liver disease, 10 cases of viral hepatitis C, and 114 cases of other etiology. There were 80 cases of Child-Pugh grade A, 289 cases of grade B, 170 cases of grade C and 10 cases lack of data. (2) Overall prevention and treatment of EVB in cirrhotic portal hypertension patients: of 271 patients in compensated stage, 38 cases received non-selective β-blocker (NSBB) therapy, 16 cases received endoscopic treatment, 6 cases received interventional therapy. Of 549 patients in decompensated stage, 68 cases received NSBB therapy, 46 cases received endoscopic treatment, 28 cases received interventional therapy. (3) Prevention and treatment of EVB in cirrhotic portal hypertension patients from different grade hospitals: of 271 patients in compensated stage, 181 cases came from tertiary hospitals, of which 28 cases received NSBB therapy, 15 cases received endoscopic treatment, 6 cases received interventional therapy. Ninety cases came from secondary hospitals, of which 10 cases received NSBB therapy, 1 cases received endoscopic treatment. There was no significant difference in NSBB for prevention of EVB between tertiary and secondary hospitals ( χ2=0.947, P>0.05), while there was a significant difference in endoscopic treatment for prevention of EVB between tertiary and secondary hospitals ( χ2=5.572, P<0.05). Of 549 patients in decompensated stage, 309 cases came from tertiary hospitals, of which 22 cases received NSBB therapy, 29 cases received endoscopic treatment, 22 cases received interventional therapy. Two hundreds and fourty cases came from secondary hospitals, of which 46 cases received NSBB therapy, 17 cases received endoscopic treatment, 6 cases received interven-tional therapy. There were significant differences in NSBB and interventional therapy for prevention of EVB between tertiary and secondary hospitals ( χ2=18.065, 5.956, P<0.05). Conclusions:The proportion of receiving EUB prevention in cirrhotic portal hypertension in Ningxia is relatively low. For patients with compensated liver cirrhosis, the proportion of NSBB therapy and endoscopic treatment in the secondary hospitals was lower than that in tertiary hospitals. For patients with decompensated liver cirrhosis, the proportion of interventional treatment in secondary hospitals is lower than that of tertiary hospitals, but the proportion of NSBB in secondary hospitals taking is higher than that of tertiary hospitals.

【Objective】 To investigate the efficacy of the adjustable "paper clip" techniques in the suture of dorsal vein complex (DVC) and retention of urethral function in robot-assisted laparoscopic radical prostatectomy (RALRP). 【Methods】 A total of 30 cases of prostate cancer treated with RALRP were enrolled, all of which used the adjustable "paper clip" techniques. During operation, the DVC was sewed with barbed suture, and then a reverse suture was made through two sides of the prostatic ligaments. A Hem-o-lock was used to fasten the suture, which would be flexible to control the degree of tightness for the ligature. Perioperative and follow-up data of urinary continence and symptoms were collected and analyzed. 【Results】 All operations were successful. The estimated blood loss was (123.3±80.7) mL, 53.6% patients recovered continence in 1 month, and the continence rate increased to 92.9% and 96.3% at month 3 and 6. 92.9 of patients had no risk of incontinence 3 months after surgery. 【Conclusion】 The adjustable "paper clip" techniques have advantages in reducing blood loss, maintaining clear surgical field, preserving urethral function, and improving urinary continence.
