Intertrochanteric fractures have become a severe public health problem in elderly patients. Proximal femoral nail anti-rotation (PFNA) is a commonly used intramedullary fixation device for unstable intertrochanteric fractures. Pelvic perforation by cephalic screw is a rare complication. We reported an 84-year-old female who fell at home and sustained an intertrochanteric fracture. The patient underwent surgery with PFNA as the intramedullary fixation device. Routine postoperative examination revealed medial migration of the helical blade that eventually caused pelvic perforation. We performed a cemented total hip arthroplasty as the savage procedure. At the latest follow-up of 12 months after total hip arthroplasty, the patient had no pain or loosening of the prosthesis in the left hip. Pelvic perforation should be considered when choosing PFNA as the intramedullary fixation device, especially in patients with severe osteoporosis wherein the helical blade can be easily inserted during the operation. The lack of devices to avoid oversliding of the helical blade in PFNA is an unreported cause of this complication and should be considered in such cases.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ² test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

OBJECTIVE: To investigate the effect and mechanism of artesunate (ARTS) combined with cytarabine(Ara-C) and/or daunorubicin (DNR) on the proliferation and apoptosis of MV4-11 human mixed-lineage leukemia rearranged（MLL-r） acute myeloid leukemia (AML) cell line. METHODS: CCK-8 assay was used to detect the proliferation effect of individual or in combination of ARTS, DNR, Ara-C on MV4-11 cells. The IC₅₀ of ARTS, DNR and Ara-C was calculated separately. The cell apoptosis and expression of receptors DR4 and DR5 were detected by flow cytometry. Western blot was used to detect the expression of Caspase-3 and Caspase-9 in each groups. RESULTS: The inhibition effect of ARTS, Ara-C and DNR on the proliferation of MV4-11 were all dose-dependently (r=0.99, 0.90 and 0.97, respectively). The IC₅₀ of ARTS, Ara-C and DNR on MV4-11 for 48 hours were 0.31 μg/ml, 1.43 μmol/L and 22.47 nmol/L, respectively. At the dose of ARTS 0.3 μg/ml， Ara-C 1.0 μmol/L and DNR 15 nmol/L, the proliferation rate for 48 hours of the tri-combination treatment was significantly lower than that of the bi-combination treatment, while both were significantly lower than that of the individual treatment (all P＜0.05). In terms of bi-combination treatment, the cells proliferation rate for 48 hours of the ARTS+Ara-C group was significantly lower than that of the ARTS+DNR group, while both were significantly lower than that of the Ara-C+DNR group (all P＜0.05). The cooperativity index (CI) of bi- and tri-combination treatment were all less than 1. After 48 hours of drug action, the cell apoptosis rate of the ARTS+DNR+Ara-C group was significantly higher than that of the Ara-C+DNR group, while both were significantly higher than that of the ARTS+DNR group (all P＜0.05). Meanwhile, the was no statistical difference between the cells apoptotic rate of the ARTS+DNR+Ara-C group and the ARTS+Ara-C group (P>0.05). The expression of DR4 and DR5 also showed no difference between control group and drug group. Compared with the DNR+Ara-C group, the expressions of Caspase-3 were significantly down-regulated in both the ARTS+DNR+Ara-C group and the ARTS+Ara-C group (all P＜0.05). The down-regulation of Caspase-3 expression was the most significantly in the combination group of three drugs, while the Caspase-9 expressions in different groups showed no apparent change. CONCLUSION The in vitro study showed that tri-combination of ARTS+Ara-C+DNR and bi-combination of ARTS+Ara-C could inhibit the proliferation and promote apoptosis of MV4-11 cell line. The inhibition effect of these two combinations were significantly superior to that of the traditional Ara-C+DNR treatment. The mechanism underlying this finding may be identified by the down regulation of Caspase-3, while no altered expression was observed of Caspase-9, DR4 and DR5.

OBJECTIVETo explore the clinical application technology of completely laparoscopy hepodectomy (LH).

METHODSFrom June 2006 to December 2011, the 126 cases of LH were performed, the data including operating time, blood loss and postoperative complications, etc, were analyzed retrospectively. The patients included 87 males and 39 female and they were 28-83 years old with an average age of 44.5 years old. The parenchyma was transected using laparoscopic ultrasonic scalpel and ligasure, accomplished with endoscopic linear stapler. Of all the patients, the diseases performed LH including primary liver carcinoma (45 cases), liver hemoangioma (58 cases), colon carcinoma with livermetastasis (23 cases), liver focar (5 cases), liver granuloma (1 case), liver adenoma (4 cases). The operations included left hemihepatectomy (n = 17), left lateral lobectomy (n = 34), right hemihepatectomy (n = 15), segmentectomy (n = 22), local resection (n = 59).

RESULTSOf all the patients, mean blood loss was 180 ml (10-1250 ml), mean surgical time was 142 minutes (43-220 minutes), mean postoperative hospital day was 2.2 days (3-12 days). Postoperative complications including eight cases of bile leakage, recovered after 1-3 weeks by appropriately draining. The patients with malignant tumor were followed up for 18 months (12-46 months), recurrence happened in 12 cases and four cases was died of recurrence and metastasis.

CONCLUSIONSLH is a safe, feasible and effective procedure for the treatment of benign liver disease and malignant liver neoplasm as long as the patient is properly selected, it should be recommended for radical resection of hepatocellular carcinoma.

OBJECTIVETo evaluate the ASES, Constant and HSS score systems and their significance on postoperative function of the shoulder.

METHODSTotally 172 cases of proximal humeral fracture of five affiliated hospital from September 2004 to September 2008 were analyzed. All the functional outcome of the involved shoulder were evaluated by ASES, Constant, HSS score and patient self score. The correlations and agreement of three shoulder scales were analyzed with Pearson correlation test and Bland-Altman plot in different age groups and fracture types.

RESULTS(1) The Constant score were lower than other two scores in the same age group and fracture type (F = 13.62 and 4.80, P < 0.05). (2) The correlations between three shoulder scales: ASES and Constant (r = 0.754, P = 0.0003), ASES and HSS (r = 0.755, P = 0.0001), Constant and HSS (r = 0.858, P = 0.0002). The correlations between three shoulder scales and patient self evaluation: ASES (r = 0.602, P = 0.0002), Constant (r = 0.705, P = 0.0001), HSS (r = 0.663, P = 0.0037). The Bland-Altman plot shows three shoulder scales have good agreement. (3)The correlation between Constant score and patient self evaluation decreased in the elder group and severe fracture type.

CONCLUSIONSASES, Constant, HSS shoulder score systems are all fit to evaluate the functional outcome of the shoulder, they have good correlation and agreement. Constant score in recommended for its high correlation coefficient with patient self evaluation score. However, its age bias must be paid attention in clinical practice. ASES shoulder score can be used in remote follow-up.

OBJECTIVETo study the clinicopathologic and immunohistochemical features, biological behavior, diagnosis and treatment of solid pseudopapillary tumor of the pancreas (SPTP).

METHODSA retrospective clinical and clinicopathologic analysis was made on 33 cases of SPTP admitted from May 2001 to 2010 July. There were 7 male and 26 female patients, aging from 13 to 66 years with a mean of 34.3 years.

RESULTSThe tumor was located in pancreatic head of 10 patients, in pancreatic neck of 5 patients, in pancreatic body and tail of 18 patients. Of the 33 patients treated with surgery, 8 underwent simple resection of pancreatic tumor, 6 underwent pancreaticoduodenectomy, 3 underwent tumor resection plus pancreaticojejunostomy, 1 underwent tumor resection plus pancreaticogastrostomy, 11 underwent distal pancreatectomy, 4 underwent distal pancreatectomy plus spleen resection (1 underwent mesohepatectomy for hepatic metastasis). Sixteen of the 33 operations were completed by laparoscopy. Histologically, tumors were composed of papillary and microcystic solid structures, with uniformed population of cells. The pancreas and blood vessels invasion were identified in 3 cases, one of them was combined with liver metastasis, and they are male. Immunohistologically, the tumors were positive for α1-antitrypsin, α1-antichymotrypsin, β-catenin, CD10, CD56 and vimentin (all cases), neuron-specific enolase (3 cases), synaptophysin (6 cases), chromogranin A (4 cases), progesterone receptor (28 cases), estrogen receptor (3 cases), S-100 (6 cases). Totally 33 cases were followed up with a median period of 49 months without tumor recurrence.

CONCLUSIONSSPTP is of low graded malignancy. It primarily affects young women. It may be located in any part of pancreas. Immunohistochemistry is very important for the diagnosis and differential diagnosis of SPTP. Surgical resection is recommended as the treatment of choice. Laparoscopic distal pancreatectomy or tumor resection is feasible and safe for some selected patients, and the prognosis is good.

OBJECTIVETo investigate prospectively the effectiveness of kyphoplasty with SKY bone expander system in treatment of compression fracture of thoracic/lumbar vertebrae and correction of the deformity.

METHODSTwenty-five patients with thoracic/ lumbar vertebral osteoporotic compression fracture were admitted to our hospital between March 2007 and March 2008, and treated by kyphoplasty with SKY bone expander system. Patient's pain status was rated with Visual Analogue Scale (VAS) score system 1 day before and 1 hour, 48 hours, 6 months, 12 months after surgery. In addition, Rolland-Morris and Oswestry disability questionnaires (RDQ and ODI) were used for survey 1 day before and 1, 6, 12 months after surgery. Pre- and post-operative vertebral heights and Cobb's angles were measured based on the X-ray films and statistically analyzed.

RESULTSThere were 27 fractured vertebrae in these 25 patients. After SKY kyphoplasty, the Cobb's angles (9.8 degree ± 9.76 degree) were significantly reduced compared with preoperative angles (17.18 degree ± 9.35 degree P < 0.05), and the average improvement rate was 39%. Patients'pain VAS scores were also greatly improved after operation (P < 0.05). Moreover, postoperative RDQ and ODI scores were significantly smaller than preoperative values (P < 0.05).

CONCLUSIONSKyphoplasty with SKY bone expander system provides an effective method for treating thoracic/ lumbar vertebral osteoporotic compression fracture, with the advantages of small surgical wound and short duration. It can effectively recover the anterior and medial heights of fractured vertebrae (33% and 50%, respectively), reduce the Cobb's angle, quickly alleviate pain and improve patients'quality of life in a relatively short time period.

OBJECTIVETo investigate the effect of chronic enhanced external counterpulastion (EECP) on gene expression profiles of arterial endothelial cells (ECs) of pigs fed with high-cholesterol diet.

METHODSEight male pigs were fed with high-cholesterol diet for 12 weeks to induce arteriosclerosis and subjected to EECP for accumulative 36 h (2 h every other day for 18 sessions). Another 8 pigs on cholesterol-enriched diet and 6 normally fed pigs served as the arteriosclerosis model group and normal control group, respectively, and the high-cholesterol diet was maintained until the end of EECP treatment. The coronary artery was then isolated for transmission electro microscopy, and the abdominal aorta was observed using Sudan III staining. The gene expression profiles in ECs from the thoracic aorta using cDNA microarrays.

RESULTSMacrophages and foam cells were detected beneath the ECs in the coronary artery of pigs in the model group, but not in the other two groups. The ratios of Sudan III-positive area in the celiac aorta were significantly lower in normal control and EECP groups than in the model control group (P<0.05). Compared with the normal control group, the gene expressions of integrins-beta1 and CTGF were up-regulated in the model group. Compared with the model group, the expressions of integrins-beta1, CTGF and VCAM-1 were down-regulated and eNOS up-regulated in EECP group.

CONCLUSIONChronic EECP may reduce endothelial injury, down-regulate the gene expression level of integrin-beta1, CTGF and VCAM-1, lower cholesterol uptake and attenuate arterial endothelial inflammation to protect the pigs fed with high-cholesterol diet from arteriosclerosis.

AIMTo explore the feasibility and safety of greenlight photoselective vaporization of the prostate (PVP) on high-risk patients presenting with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH) and to evaluate their clinical and voiding outcome.

METHODSA total of 85 high-risk patients with obstructive BPH underwent PVP with an 80 W potassium-titanyl-phosphate laser, which was delivered through a side-deflecting fiber with a 23 Fr continuous flow cystoscope. Operative time, blood loss, indwelling catheterzation, international prostate symptom score (IPSS), quality of life score (QoL), uroflowmetry, postvoid residual urine volume and short-term complication rates were evaluated for all patients.

RESULTSAll patients got through the perioperative period safely. The chief advantages of PVP were: short operative time (25.6 +/- 7.6 min), little bleeding loss (56.8 +/- 14.3 mL) and short indwelling catheterization (1.6 +/- 0.8 d). The IPSS and QoL decreased from (29.6 +/- 5.4) and (5.4 +/- 0.6) to (9.5 +/- 2.6) and (1.3 +/- 0.6), respectively. The vast majority of patients were satisfied with voiding outcome. The mean maximal urinary flow rate increased to 17.8 mL/s and postvoid residual urine volume decreased to 55.6 mL. These results are significantly different from preoperative data (P < 0.05). No patient required blood transfusion or fluid absorption. There were few complications and very high patient satisfaction after operation.

CONCLUSIONPVP has a short operative time and high tolerance, and is safe, effective and minimally invasive for high-risk patients, therefore it might be considered as a good alternative treatment for high-risk patients with obstructive urinary symptoms as a result of BPH.
