OBJECTIVE: To compare the efficacy of percutaneous pedicle screw combined with unilateral nail placement combined with bone cement strengthening and bilateral nail placement in the treatment of osteoporotic thoracic and lumbar fractures. METHODS: A retrospective case-control study was used to analyze the clinical data of 78 patients with osteoporotic thoracic and lumbar fractures admitted from October 2017 to May 2019. According to the surgical method, it was divided into percutaneous pedicle screw combined with unilateral nail placement combined with unilateral bone cement strengthening group(bone cement group) and percutaneous pedicle screw combined with bilateral nail placement(screw group). In the bone cement group, 40 patients included 16 males and 24 females, with a mean age of (62.1±8.1) years old. In the screw group, 38 patients included 18 males and 20 females with a mean age of (65.1±9.3) years old. The operation time, intraoperative blood loss, length of hospital stay and postoperative complications were compared between two groups. The kyphosis Cobb angle, anterior edge height ratio, central height ratio and pain visual analogue score(VAS) were compared. RESULTS: All patients were followed up for 25 to 36 months. The operation time (70.1±17.3) min of the cement group was shorter than that of the screw group (78.6±18.2) min(P<0.05). There were no significant differences in intraoperative blood loss and length of hospital stay(P>0.05). The VAS in the cement group 1 year 1.5±0.5 and the latest follow-up 0.5±0.3 after operation were lower than 1 year 1.8±0.3 and the latest follow-up 0.8±0.4 in the screw group(P<0.05). The kyphosis Cobb angle, anterior edge height ratio, central height ratio in bone cement group, 1 year (6.2±1.2)°, (86.6±3.5)%, (91.1±2.5)%, the last follow-up (6.4±0.7)°, (85.5±3.3)%, (90.5±6.3)% were better than that of the screw group 1 year (6.8±1.4)°, (83.1±2.4)%, (89.9±3.4)% and the latest follow-up (7.1±1.1)°, (82.6±4.1)%, (87.6±5.9)%(P<0.05). There were 3 cases of bone cement leakage in the cement group, all of which had no clinical symptoms;and 2 cases of pedicle screws were extracted in the screw group, and the screws were removed at the last follow-up. CONCLUSION Percutaneous pedicle screw combined with unilateral nail placement combined with bone cement strengthening and bilateral nail placement in the treatment of osteoporotic thoracic and lumbar compression fractures in the elderly can achieve satisfactory efficacy and effectively relieve the pain of patients, but the former internal fixation system is more stable, and the long-term follow-up can effectively maintain the height of the anterior middle column and the correction of kyphosis deformity, and the incidence of chronic low back pain is lower.

Objective:To investigate the treatment and prognosis of patients of G3 non-functional pancreatic neuroendocrine tumors (pNETs) with proliferation index of Ki-67 <55%.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 15 G3 non-functional pNETs patients with proliferation index of Ki-67<55% who were admitted to Zhongshan Hospital of Fudan University from April 2014 to April 2020 were collected. There were 11 males and 4 females, aged (58±10)years. All patients underwent radical resection of the primary lesion. Obser-vation indicators: (1) treatment; (2) postoperative pathological characteristics; (3) follow-up. Measure-ment data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M( Q1, Q3) or M(range). Count data were described as absolute numbers. The Pearson correlation analysis was used to verify the correlation between variables. Kaplan-Meier method was used to draw survival curve and calculate survival rate. Log-Rank test was used for survival analysis. Results:(1) Treatment. All 15 G3 nonfunctional pNETs patients underwent radical resection of the primary lesion of pancreas, including 5 cases receiving pancreati-coduodenectomy, 10 cases receiving distal pancreatectomy with splenectomy. There were 5 patients with simultaneous liver oligometastasis who underwent combined segmental (lobectomy) hepatectomy. All 15 patients had negative tumor margin, and the operation time and volume of intraoperative blood loss of 15 patients was 120(90,210)minutes and 200(50,300)mL, respectively. None of patient had complications ≥Ⅲ grade of the Clavien-Dindo classification during the postoperative 30 days. Of the 15 patients, there were 5 cases receiving comprehensive treatment based on CAPTEM chemo-therapy (temozolomide combined with capecitabine), 2 cases receiving local interventional therapy, 2 cases receiving CAPTEM chemotherapy, 1 case receiving local interventional therapy combined with molecular targeted therapy, 1 case receiving local interventional therapy combined with long acting somatostatin therapy, 1 cases receiving long acting somatostatin therapy combined with molecular targeted therapy, and 3 cases without postoperative treatment. (2) Postoperative patholo-gical characteristics. The tumor diameter of 15 patients was 3.3(range, 0.5-6.0)cm. There were 2 cases with tumor diameter <2 cm, 13 cases with tumor diameter ≥2 cm. The number of lymph nodes dissected and number of lymph nodes metastatic was 6(4, 10) and 2(1,3) in 15 patients, respectively, including 12 cases with positive lymph node metastasis. Of the 15 patients, there were 5 cases with tumor invasion of adjacent organ, 5 cases with simultaneous liver metastasis, 8 cases with perineural invasion and 8 cases with vascular invasion. There were 3, 7, and 5 patients with stage Ⅱ, stage Ⅲ, and stage Ⅳ of pathological TNM staging, respectively. The proliferation index of Ki-67 and mitotic count was 32%±9% and (11±9)/10 high power field in the primary lesion of 15 patients, respectively, and there was no correlation between proliferation index of Ki-67 and mitotic count ( P>0.05). (3) Follow-up. All 15 patients were followed up after surgery for (55±24)months. The median survival time of 15 patients was 78(range, 43-113)months, with 1-, 3-, 5-year overall survival rate as 100%, 92%, 62%, respectively. During the follow up, 9 of the 15 patients underwent tumor recurrence, with the recurrence time as 20(14, 44)months. There were 8 patients died of tumor recurrence or metastasis. The median survival time was 86(range, 51-120)months in 5 patients receiving comprehensive treatment based on CAPTEM chemotherapy, versus 53(range, 45-60)months in 10 patients receiving other postoperative adjuvant therapy or without postoperative treatment, showing a significant difference between them ( χ2=4.21, P<0.05). Conclusion:The prognosis of patients of G3 nonfunctional pNETs with proliferation index of Ki-67<55% undergoing radical resection combined with postoperative comprehensive treatment based on CAPTEM chemotherapy in better than that of patients receiving other postoperative adjuvant therapy or without posto-perative treatment.

Objectives:To evaluate the role of pancreas multidisciplinary team(MDT) clinic in the diagnosis of pancreatic diseases,patient compliance with MDT advice,and the impact of MDT on the postoperative survival of patients with pancreatic cancer.Methods:The study included 927 patients(554 males,373 females,aged (58.1±13.3)years (range: 15 to 89 years)) that had visited the pancreas MDT clinic of Zhongshan Hospital from May 2015 to December 2021,and 677 patients(396 males, 281 females, aged (63.6±8.9)years(range: 32 to 95 years)) who underwent radical surgery and with pathologically confirmed pancreatic adenocarcinoma from January 2012 to December 2020,of whom 79 patients had attended the pancreas MDT. The clinical and pathological data were collected and analyzed retrospectively. Diseases were classified in accordance with 2010 WHO classification of tumors of the digestive system and usual clinical practices. The Kaplan-Meier method was used for drawing the survival curve and calculating the survival rate. The univariate analysis was done by Log-rank test and the multivariate analysis was done by COX proportional hazards model. Survival rates were compared using χ 2 test. Results:Among the 927 patients that had visited the MDT clinic,233 patients(25.1%) were referred due to undetermined diagnosis. A direct diagnosis was made in 109 cases (46.8%,109/233) by the MDT clinic, of which 98 were consistent with the final diagnosis,resulting in an accuracy of 89.9%(98/109). The direct diagnosis rate in the recent years(36.6%(41/112),from June 2019 to December 2021) decreased compared to that in the previous years(56.2%(68/121),from May 2015 to May 2019),yet the accuracy in the recent years(90.2%,37/41) was basically the same as before (89.7%,61/68). The rate of compliance of the entire cohort was 71.5%(663/927), with the compliance rate in the recent two and a half years(81.4%,338/415) remarkably higher than that in the previous four years(63.4%,325/512). Patients with pancreatic cancer that attended the MDT exhibited a trend toward longer median postoperative survival than patients that did not attend the MDT,but the difference was not statistically significant(35.2 months vs.30.2 months, P>0.05). The 1-year and 3-year survival rates of patients that attended the MDT were significanly higher than patients that did not attend the MDT(88.6% vs. 78.4%, P<0.05;32.9% vs. 21.9%, P<0.05,respectively),but the 5-year survival rate was not statistically different(7.6% vs. 4.8%, P>0.05). Conclusions:The pancreas MDT clinic is an accurate and convenient way to diagnose intractable pancreatic diseases,and in the recent years the patients′ compliance rate with MDT advice has increased. Pancreatic cancer patients that have attended the MDT have higher 1-year and 3-year postoperative survival rates,but the long-term survival benefits of MDT still needs to be proved by clinical studies on a larger scale.

Objective: To explore the clinical application of supraclavicular fasciocutaneous island flap (SIF) in the repair of tracheal defect. Methods: From May 2016 to March 2021, the clinical data of 10 patients (8 males,2 females,aged 27-73 years old) were retrospectively analyzed who underwent repair surgery with SIF for trachea defects after resection of cervical or thoracic tumors, including 2 cases of laryngotracheal adenoid cystic carcinoma, 2 cases of laryngeal carcinoma, 3 cases of esophageal carcinoma, 2 cases of thyroid carcinoma and one case of parathyroid carcinoma. All of the primary tumors were at T4. The outcomes of 10 cases with tracheal defect repaired by SIF were evaluated. Results: The areas of the SIF were (3-7) cm × (6-10) cm, the thicknesses of the flaps were 8-11 mm, and the lengths of the pedicles were 10-15 cm. The blood supply of the SIF came from the transverse carotid artery. The skin defects of the donor areas of the shoulders were directly closed. After 1-60 months of follow-up, all the flaps survived. The flaps, tracheas as well as shoulder wounds healed well. Conclusion: The SIF is suitable for the repair of tracheal defects. It has perfect thickness compatible with the trachea. The technique is simple and microsurgical technique is not needed, with a good application prospect.

OBJECTIVE: To observe the clinical efficacy of warm acupuncture combined with yoga posture method in the treatment of periarthritis with frozen period. METHODS: Ninety patients with periarthritis who met the inclusion criteria were randomly divided into a control group 1, a control group 2 and an observation group, 30 cases in each group. Warm acupuncture was applied in the control group 1 (Jianzhen (SI 9), Jianyu (LI 15), Jianliao (TE 14), etc were selected), yoga posture method was applied in the control group 2, warm acupuncture combined with yoga posture method were given in the observation group, the treatment was given once a day, 10 times as a course with 2 days between courses and continuous for 2 courses. After 2 courses of treatment, the shoulder joint pain score and shoulder function grading were used to evaluate the clinical efficacy, and the clinical efficacy was observed. RESULTS: ①The pain scores of the three groups were significantly lower after treatment (all <0.01), and scores in the observation group was better than that in the control group 1 and the control group 2 (<0.05, <0.01). There was no significant difference between the control group 1 and the control group 2 (>0.05). ②After treatment, the functional classification of shoulder joints were significantly improved in the three groups (all <0.01), and the functional classification of shoulder joint in the observation group and the control group 2 were better than that in the control group 1 (<0.01, <0.05). There was no significant difference between the observation group and the control group 2 (>0.05). ③After 2 courses of treatment, the effective rate of the observation group was 86.7% (26/30), which was better than 70.0% (21/30) in the control group 1 and 76.7% (23/30) in the control group 2 (both <0.05). CONCLUSION Warm acupuncture combined with yoga posture method can effectively relieve shoulder pain and improve dysfunction. The clinical comprehensive effect is better than simple acupuncture and yoga posture method.

Common bile duct (CBD) stones are a frequent problem in Chinese populations, and their incidence is particularly high in certain areas (Wang et al., 2013). In recent years, laparoscopic common bile duct exploration (LCBDE) and endoscopic retrograde cholangiopancreatography (ERCP) have been the main surgical procedures for CBD stones, although each has different advantages and disadvantages in the treatment of choledocholithiasis (Loor et al., 2017; Zhou et al., 2017). For patients with large stones, a dilated CBD, especially concurrent gallstones, LCBDE is the preferred and most economical minimally invasive procedure (Koc et al., 2013). However, a T-tube is often placed during LCBDE to prevent postoperative bile leakage; this is associated with problems such as bile loss, electrolyte disturbance, and decreased gastric intake (Martin et al., 1998). In addition, the T-tube usually must remain in place for more than a month, during which time the patient's quality of life is seriously compromised. Many skilled surgeons currently perform primary closure of the CBD following LCBDE, which effectively speeds up rehabilitation (Hua et al., 2015). However, even in sophisticated medical centers, the incidence of postoperative bile leakage still reaches ≥10% (Liu et al., 2017). Especially for a beginner, bile leakage remains a key problem (Kemp Bohan et al., 2017). Therefore, a safe and effective minimally invasive surgical approach to preventing bile leakage during primary closure of the CBD after LCBDE is still urgently needed.
