Objective To determine whether the poking reduction and bone grafting technique with guide through bony tunnel can correct a Hill-Sachs lesion. Methods A total of 30 cadaveric humeri were equally divided into three groups, 10 cadaveric humeri per group. Hill-Sachs lesions were replicated with a osseous defect involving 10% (group A ) , 20% (group B ) and 30% (group C ) of the articular surface. All the bone defects in each group were measured and the poking reduction and bone grafting technique with guide through a bony tunnel was performed in group B and group C. The preoperative and postoperative transverse arc length, longitudinal are length, depth and volume of the osseous defects in group B and group C were compared by using paired t test. Results Before reduction, the transverse arc length of the bone defects was ( 10.9 ± 1.4 )mm in group B and ( 16.3 ± 2.3 ) mm in group C ; longitudinal arc length was ( 22.4 ± 2.4 ) mm in group B and ( 28.0 ± 2.2 ) mm in group C ;depth was (6.9±0.9) mm in group B and (11. 1 ±0.9) mm in group C; volume was (708.7±93.9) mm3 in group B and (1338.3 ± 185.6) mm3 in group C. After reduction, the transverse arc length of the bone defects was (5.1 ± 2.4 ) mm in group B and ( 7.6 ± 3.6 ) mm in group C ; longitudinal arc lengthwas (10.5 ±4.9) mm in group B and (12.3 ±5.3) mm in group C; depth was (0.3±0.1 ) mm in group B and (0.4 ±0.1 ) mm in group C; volume was (48.9 ± 16.1 )mm3 in group B and (70.3 ± 37.9) mm3 in group C. The comparison of all the parameters showed statistical difference (P <0. 01 ). Conclusion The poking reduction and bone grafting technique with guide through a bony tunnel can effectively correct the Hill-Sachs lesions with humeral head osseous defects involving 20% -30% of the articular surface.

OBJECTIVETo analyze the perioperative complications of percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture.

METHODSFrom June 2009 to December 2011, 63 patients with osteoporotic vertebral compression fracture underwent PKP, there were 18 males and 45 females with an average age of 75.3 years ( ranged, 62 to 91). All patients with severe back pain and without neurological symptoms and signs, which were confirmed by X-ray and MRI. Among them,there were 63 cases with severe osteoporosis, 37 cases with hypertension, 10 with coronary artery disease, 29 with anemia, 26 with diabetes, 11 with chronic obstructive pulmonary diseases and 8 with gastritis and peptic ulcer. The common perioperative complications were retropectively reviewed.

RESULTSPreoperative complications occured in 9 cases (14.3%), including hypostatic pneumonia (1 case), electrolyte disturbances (2 cases), urinary tract infection (2 cases), moderate anemia(2 cases),electrolyte disturbances combined with moderate anemia (1 case), hypostatic pneumonia combined with delirium (1 case). Intraoperative and postoperative. complications occurred in 17 cases (26.9%), there were bone cement correlated complications in 9 cases (14.3%), in which 2 cases of toxic reaction of bone cement and 7 cases of leakage (2 cases had clinical symptoms); there were non-bone cement correlated complications in 3 cases (4.8%), in which 1 case of focal hematoma caused by paracentesis, 1 case of transient nerve injury, 1 case of left intercostal neuralgia;there were transient hyperpathia in 5 cases after operation. All complications result in no severe consequence after treatment.

CONCLUSIONPerioperative complications of percutaneous kyphoplasty are not uncommon,however,these complications may not cause serious consequence after active treatment,so prevention and treatment are important for it.

OBJECTIVETo explore the clinicopathological characteristics and prognostic factors of primary gastric lymphoma (PGL).

METHODSThe clinical data of 204 patients with PGL was reviewed and analyzed. There were 106 males and 98 females, their age were 19 to 85 years (average age was 53.7 years). The Focal areas included gastric fundus lesions 41 cases (20.1%), stomach body lesions 127 cases (62.3%), distal gastric lesions 105 cases (51.5%), cardia lesions 13 cases (6.4%), duodenal bulb lesion 1 cases (0.5%). The clinical characteristics and the outcomes in patients with influence were analysed.

RESULTSIn 204 PGL patients, the most common complaints were abdominal pain (62.3%) and weight loss (52.9%). Most of the PGL patients appeared ulcerative (76.0%) and results showed that 62.7% patients involved single location. As to the factors of cellulate grading and pathological characteristics, most patients (87.7%) show low-grade or intermediate-grade lymphoma, Musshoff stages I and II (74.0%). In 186 patients with complete follow-up data, survival rates of 1-, 3- and 5-year were 75.8%, 63.4% and 60.2% respectively. The median overall survival time was 50.0 months. In univariate survival analysis, age (χ(2) = 5.030), level of LDH (χ(2) = 40.084), cellulate grading (χ(2) = 35.238), Musshoff stage (χ(2) = 71.601), tumor diameter (χ(2) = 12.018) and option of managements (χ(2) = 14.140) were obviously correlated with the prognosis (all P < 0.05). Musshoff stage (RR = 2.230, 95%CI: 1.372 - 3.625) and cellulate grading (RR = 1.892, 95%CI: 1.010 - 3.543) were independent prognostic factors in multivariable analysis (both P < 0.05). There was no prognostic difference between surgery and chemotherapy in stage I and II (χ(2) = 1.223, P = 0.542).

CONCLUSIONSMusshoff stage and grade malignancy are independent prognostic factors. For patients with stage I and II, surgical resection is not the first-choice for clinical therapy.

OBJECTIVETo explore the prognostic factors and to compare chemotherapy alone versus surgical resection plus chemotherapy for early stage primary gastric diffuse large B-cell lymphomas (DLBCL).

METHODSClinical data of 75 patients who were diagnosed as primary gastric DLBCL between January 1993 and August 2008 in Cancer Institute and Hospital of Tianjin Medical University were reviewed retrospectively.

RESULTSAmong these 75 patients, 20 patients received chemotherapy alone and 55 underwent surgical resection plus chemotherapy. Complete remission rates were 65.0% (13/20) and 83.6% (46/55), effective rates were 75.0% (15/20) and 92.7% (51/55), and 5-year survival rates were 86.9% and 78.7% respectively in chemotherapy alone group and resection plus chemotherapy group, while the differences were not statistically significant (all P>0.05). Multivariate Cox regression model showed that international prognosis index (IPI) was the only independent prognostic factor (P<0.05, HR=11.350, 95%CI:1.011-127.371).

CONCLUSIONSIn early stage of DLBCL, IPI is the only independent prognostic factor. The clinical outcomes are comparable between chemotherapy alone and surgical resection plus chemotherapy.

OBJECTIVETo explore the risk factors for early recurrence (recurrence within 2 years) of proximal gastric cancer after radical resection.

METHODSThe clinical data of 367 proximal gastric cancer patients who underwent radical resection in the Cancer Institute and Hospital of Tianjin Medical University between January 2000 and May 2006 were reviewed. Among them, there are 71 patients (19.3%) with early recurrence. Univariate analysis and multivariate analysis were applied to investigate risk factors for early recurrence.

RESULTSUnivariate analysis showed that Borrmann type (P<0.01), histology type (P<0.01), depth of invasion (P<0.05), negative lymph nodes count (P<0.05) were risk factors for early recurrence of proximal gastric. On multivariate analysis, histology type (P<0.05), depth of invasion (P<0.05), negative lymph nodes counts (P<0.05) were independent risk factors for early recurrence of proximal gastric cancer. Negative lymph nodes in early recurrence patients were 8.4 ± 7.2, which were significantly less as compared to patients without early recurrence (10.7 ± 8.7) (P<0.05).

CONCLUSIONFor T3 proximal gastric adenosquamous cancer, extended resection and lymphadenectomy should be considered. Intraoperative or postoperative adjuvant treatment should be administered as routine.

Objective:To explore the potential categories of resourcefulness in primary caregivers of stroke patients and analyze the differences in the characteristics of different types of caregivers, so as to provide basis for clinical construction of effective intervention plans.Methods:The 308 primary caregivers of stroke patients who met the research standards in the Department of Neurology of General Hospital of Ningxia Medical University, People′s Hospital of Ningxia Hui Autonomous Region, the First People′s Hospital of Yinchuan from December 2020 to August 2021 were selected as the research objects by convenient sampling method.The general information questionnaire, Resourcefulness Scale and Social Support Revalued Scale were used for cross-sectional investigation.Results:The resourcefulness of the primary caregivers of stroke patients were divided into 2 potential categories: low resourcefulness group (62.7%, 193/308) and high resourcefulness group (37.3%, 115/308). Uni-variate analysis showed that there were differences between potential categories: age and education level of stroke patients, whether there was long-term medication history, number of other chronic diseases, had there been any complications due to illness, age, education level and occupation of caregivers, average daily care duration, family relations, and social support ( χ2 values were -3.34 - 23.62, all P<0.05). Logistic regression analysis showed that social support and education level of caregivers were the influencing factors of caregiver resourcefulness ( P<0.05). Conclusions:The resourcefulness in the primary caregivers of stroke patients has certain characteristics. Clinically, targeted intervention measures should be formulated according to the different types of caregiver resourcefulness characteristics of caregivers and their influencing factors to improve the caregiver resourcefulness of stroke patients.

OBJECTIVETo explore clinical efficacy of hip replacement for hip-joint diseases with Parkinson disease.

METHODSFrom December 2011 to December 2016, 18 patients with hip-joint diseases with Parkinson disease treated by hip replacement, including 8 males and 10 females aged from 59 to 87 years old with an average of 71 years old. Among them, 3 cases were developmental dysplasia of hip, 3 cases were femoral head necrosis and 12 cases were femoral neck fracture. All patients manifested with obvious pain and limitation of stepping ability. Postoperative complications were observed and Harris score were used to compare hip joint function after operation.

RESULTSThe incision were healed well, and pain were alleviated or disappeared, and hip joint function were improved. Eighteen patients were followed up from 1 to 3 years with an average of 2.3 years. At the latest follow up, 14 cases recovered freedom-walk, 2 cases could walk with walking stick, 1 case could walk with walking aid and 1 case was died. Among 18 patients, 2 cases were occurred dislocation, and 1 case were died for cardiac disease at 3 months after operation. Four patients were occurred slight pain. There were significant differences in Harris scores among preoperative (41.7±1.4), 6 months after operation(80.1±5.4) and the final follow-up (83.4±2.1), and 10 cases got excellent result, 4 good, 1 fair and 2 poor.

CONCLUSIONSApplication of hip replacement for hip-joint diseases with Parkinson disease is a safe and effective clinical therapy, and has advantages of less complications and rapid recovery of hip joint function.

OBJECTIVETo evaluate the clinical efficacy of uncut Roux-en-Y reconstruction after distal gastrectomy for gastric cancer.

METHODSClinical data of 419 patients who underwent distal gastrectomy for gastric cancer with complete follow-up data between March 2005 and March 2008 in the Cancer Institute and Hospital of Tianjin Medical University. Patients were divided into B I (138 cases with Billroth I reconstruction), M-B II (108 cases with modified Billroth II reconstruction), RY (46 cases with Roux-en-Y reconstruction) and Uncut RY (127 cases with uncut Roux-en-Y reconstruction) according to reconstructive methods.

RESULTSPatients in the Uncut RY group had a larger tumor diameter, more T3, and poorer stage of disease compared to those in the B I (P<0.05). In Uncut RY group, the operative time and postoperative hospital stay were(132.6±19.2) minutes and (10.4±1.2) days respectively, shorter than those in RY group (142.5±11.7) minutes and (12.1±3.7) days(both P<0.05), alkaline reflex gastritis rate was 3.2%, lower than that in B I group (24.6%, P<0.05) and M-B II group (25.9%, P<0.05). Marginal ulcer rate in uncut RY group was lower compared to M-B II group (P=0.019), and incidence of Roux-en-Y stasis syndrome was less compared to RY group (P=0.000).

CONCLUSIONSThe uncut Roux-en-Y reconstruction is both feasible and safe. It can prevent alkaline reflex gastritis and Roux-en-Y stasis syndrome. It may be the preferred technique for reconstruction after distal gastrectomy.

OBJECTIVETo investigate the clinical features and prognosis of recurrent gastric cancer.

METHODSClinical data of 163 patients with recurrent gastric cancer from Jan. 2001 to Jan. 2005 were reviewed. Patients were compared between those with and without symptoms.

RESULTSSeventy-two patients(44.2%) were symptomatic, while 91(55.8%) were asymptomatic. There were significant differences in lymph node metastasis between the two groups(P<0.05). The median overall survival was significantly longer in asymptomatic patients (19.8 vs. 15.7 months, P<0.05). Post-recurrence survival was also longer in the asymptomatic group (9.5 vs. 4.8 months, P<0.01). The median recurrence-free interval in asymptomatic patients was 10.0 months, which was significantly longer than that in the symptomatic patients (9.2 months, P<0.05). On univariate survival analysis,post-gastrectomy chemotherapy (P<0.05), symptoms of recurrence(P<0.01), TNM staging(P<0.01), recurrence-free interval (P<0.01), and reoperation(P<0.01) were associated with the prognosis. On multivariable analysis, TNM staging(P<0.01), symptoms of recurrence(P<0.01), recurrence-free interval (P<0.05), and reoperation(P<0.05) were independent risk factors.

CONCLUSIONSPatients with recurrent gastric cancer have poor prognosis. Close monitoring and active follow-up of patients with gastric cancer should be conducted during the first two years after operation. Reoperation may improve survival in patients with recurrent gastric cancer.

OBJECTIVETo investigate the clinicopathological characteristics and prognostic factors of bone metastasis in gastric cancer patients.

METHODSClinicopathological data of 66 gastric cancer patients with bone metastasis, who were treated at the Tianjin Medical University Cancer Institute and Hospital from October 1997 to September 2011, were analyzed retrospectively. The clinicopathological characteristics of the primary cancer and bone metastasis were summarized and the prognosis was analyzed.

RESULTSOf 66 patients, 4 underwent operation, 28 chemotherapy, 32 inhibitors of bone resorption,8 local treatment and 23 symptomatic treatment alone. The median survival time of these 66 patients was 5 months (95%CI:3.3-6.7 months). The 1-, 2- and 3-year survival rates were 9.1%, 3.0% and 1.5%, respectively. Univariate Log-rank test indicated that gender, bone metastasis combined with other distant metastasis and chemotherapy were significant prognostic factors (all P<0.05). Multivariate analysis revealed bone metastasis combined with other distant metastasis was an independent prognostic factor (P=0.011, RR=2.067, 95%CI:1.178-3.626).

CONCLUSIONSPrognosis of patients with bone metastasis from gastric cancer is poor. Chemotherapy-based comprehensive treatment may improve the prognosis of these patients.
