OBJECTIVETo optimize the best acupuncture therapy in the treatment of lumbar disc herniation (LDH) and to explore its mechanism in terms of immunology.

METHODSOne hundred and eleven cases were randomized into an acupuncture-moxibustion group, an elongated needle group and a herb-partitioned moxibustion group, 37 cases in each group. In acupuncture-moxibustion group, penetration needling with elongated needle was applied at Dachangshu (BL 25), Guanyuanshu (BL 26) and Huantiao (GB 30), which was followed with herb-partitioned moxibustion at Shenque (CV 8) and Yaoyangguan (GV 3), etc, once a day. Elongated needle and herb-partitioned moxibustion were applied in the elongated needle group and herb-partitioned moxibustion group respectively. The efficacy of each group was observed after 21 treatments and the value of serum immunoglobulin was measured and analyzed before and after treatment.

RESULTSThe effective rate was 97.3% (36/37) in acupuncture-moxibustion group, which was superior to 75.7% (28/37) in the elongated needle group and 73.0% (27/37) in the herb-partitioned moxibustion group (both P<0.05). The visual analogue scale (VAS), straight-leg raising range and motion range of the lumbar vertebra in three groups were all improved after treatment (all P<0.05), which was more significant in the acupuncture-moxibustion group (all P<0.05). The difference of value of serum immunoglobulin before and after treatment was significant in the acupuncture-moxibustion group (P<0.05), which was not in the elongated needle group and the herb-partitioned moxibustion group (both P>0.05).

CONCLUSIONThe therapy of elongated needle combined with herb-partitioned moxibustion achieves superior efficacy in the treatment of LDH as compared with elongated needle or herb-partitioned moxibustion therapy, and it can regulate the humoral immunity system of patients.

OBJECTIVETo evaluate the periodontal conditions after the wedge-shaped defect was restored by gingival retraction technique.

METHODSA total of 138 mandibular premolars with wedge-shaped defect were selected and divided into A, B groups. Group A was restored with Dyract after using retraction cord. Group B was directly restored with Dyract. Clinical parameters including plaque index (PLI), gingival index (GI), sulcus bleeding index (SBI), probing depth (PD), volumes of gingival crevicular fluid (GCF) and levels of aspartate aminotransferases (AST) of gingival crevicular fluid were measured at baseline, 1 week, 1 month, 3 months and 6 months after operation.

RESULTSThere was no difference in PLI, GI, SBI, PD between group A and B during 6 months after operation, while the difference of GCF and AST was significant between group A and B at 3 months and 6 months after operation (P < 0.05, P < 0.01).

CONCLUSIONSGingival retraction technique applied in wedge-shaped defect restoration can reduce the damage to the periodontal tissue.

BACKGROUND: The majority of children with β-thalassemia major have iron overload, and iron overload may have negative effects on hematopoietic stem cell transplantation. OBJECTIVE: To assess the effects of liver and cardiac iron overload detected by magnetic resonance imaging (MRI) T2* on HLA-identical allogeneic hematopoietic stem cell transplantation in children with β-thalassemia major. METHODS: Eighty-one children with β-thalassemia major who were over 3 years of age and could cooperate with MRI detection were subjected to liver and heart MRI T2* tests before or after HLA-identical allogeneic hematopoietic stem cell transplantation. According to the test results, we calculated the liver and cardiac iron content, defined as an indicator of liver and heart iron overload. Then, there was a correlation analysis between the liver and cardiac iron content and serum ferritin, time of hematopoietic reconstitution, mortality rate, implantation rate and the morbidity of transplantation related complications, such as graft-versus-host disease, infections, autoimmune hemolysis, pancytopenia, hepatic veno-occlusive disease, septicemia. RESULTS AND CONCLUSION: The liver iron content was positively correlated with the time of hemoglobin implantation (r=0.229, P=0.043), and the cardiac iron content were positively correlated with the mortality rate (r=0.266, P=0.017); the serum ferritin level was negatively correlated with the implantation rate (r=-0.289, P=0.009), and positively correlated with the morbidity of septicemia (r=0.251, P=0.024) and pancytopenia (r=0.276, P=0.013). Therefore, iron overload exerts negative effects on HLA-identical allogeneic hematopoietic stem cell transplantation in β-thalassemia major children, and it is necessary to detect serum ferritin level and assess liver and cardiac iron overload before cell transplantation.

OBJECTIVETo explore the effect of one dressing of porcine acellular dermal matrix on deep partial thickness burns.

METHODSFrom January 1997 to January 2004, sixty-seven cases of deep partial thickness total burned surface area (TBSA) from 50% to 90% burn wound were treated by a single dressing of porcine acellular dermal matrix (the porcine acellular dermal matrix group). Ten cases of deep partial thickness burned patients with the same TBSA treated by exposure method served as the exposure method group. The healing time of the wound was observed. The patients were followed up for 3 months to 2 years, and the scar proliferation was observed.

RESULTSThe deep partial-thickness wound would be healed without dressing change in the porcine acellular dermal matrix group, and the average healing time was (12.2 +/- 2.6) days. The average healing time of the exposure method group was (27.4 +/- 3.5) days. Follow up of the patients within 3 months to 2 years showed that scar proliferation in the porcine acellular dermal matrix group was much less than that in the exposure method group, even no scar proliferation was observed in some patients.

CONCLUSIONWithout tangential excision, autografting and dressing change, a single dressing of porcine acellular dermal matrix on deep partial thickness burn wound could shorten the healing time and inhibit scar proliferation.

OBJECTIVETo evaluate the effectiveness and the practicability of the Acute Lymphoblastic Leukemia Berlin-Frankfurt-Münster 95 (ALL-BFM 95) protocol in treating childhood high-risk acute lymphoblastic leukemia (HR-ALL).

METHODSA retrospective analysis of 47 children with newly diagnosed HR-ALL between July 2003 and August 2013 was performed. These children were treated by the ALL-BFM 95 protocol. Survival was evaluated by Kaplan Meier analysis and Log-Rank test.

RESULTSRelapse-related death occurred in 12 of 47 patients (26%), and 5 of 47 patients (11%) were treatment-related mortality. Five-year probability of event-free-survival (pEFS) was 62%. Children with hematopoietic stem cell transplantation (HSCT) after chemotherapy achieved significantly better pEFS than those with chemotherapy alone (77% vs 52%; P=0.035). The patients who were only poor responders to prednisone had a better outcome (5-year pEFS 80%) than the Days 15 and 33 bone marrow M3 subgroups (5-year pEFS 60% and 0 respectively).

CONCLUSIONSALL-BFM 95 protocol can improve the outcome of children with high-risk ALL. The major cause of death is attributed to relapse. Chemotherapy plus HSCT can produce a better outcome than chemotherapy alone. The Days 15 and 33 bone marrow M3 subgroups have a poor prognosis.

OBJECTIVETo explore the factors associated with retention in a community-based methadone maintenance treatment(MMT) among drug users in Urumqi.

METHODSWith national MMT guideline( drift) for heroine addicted drug users, local heroine-dependent people were admitted to community-based MMT program affiliated to Xinjiang Uigur Autonomous Region Center for Mental Health. Data on outpatients' social-demo characteristics, baseline behaviors on drug use and daily stabilized dose of drugs were entered to MMT database.

RESULTSUp to 10, Feb. , 2006,353 persons withdrew MMT treatment among 709 heroin dependant drug users. Between 11, Aug., 2005 and 10, Feb., 2006, with median duration as 77 days, cumulative drop-out rate of 90 days and 180 days after first dose of MMT were 73.8% among 455 and 99.4% among 355 drug users, respectively. The incidence of drop-outs was 29.8 per 100 person-month. The median length of stay (days) in MMT was 68.0 (95% CI: 59.0- 78.0). Correlates of retention were found as: Being Uigur(HR = 1.35;95% CI :1.09-1.67), duration of drug use (HR =0.74; 95% CI:0.55-0.99) and stabilized dose(HR = 0.60;95% CI: 0.48-0.74) was found in multiple Cox proportional hazard regression model.

CONCLUSIONRetention of MMT among drug users in Urumqi was low. Uigur people should be given individual counseling to help them increase the compliance rate. Within the ranges of clinic dosage, adjustment of the methadone dose on an individual base might serve as an appropriate approach to increase the effectiveness of the program.

OBJECTIVETo design ABC damage variable and positioning system for acetabular fracture and explore the feasibility and clinical practical value of the system through the multi-center analysis of 1122 acetabular fractures.

METHODSAccording to acetabular three-column conception, and pelvic ring lesions damage direction caused by acetabular fracture domino effect and injury degree of proximal femur joint, it defined class A as any column acetabular fracture; class B as any two-column acetabular fracture; class C as front, dome and posterior mixture acetabular fracture. Lower case English letters a, m, p represented front, dome, posterior fracture, respectively. Acetabular damage variables: 1 was simple displaced fractures; 2 was comminuted fractures; 3 was compression fractures. Pelvic ring lesions damage variables: alpha was sacroiliac joints or sacroiliac fracture horizontal separation deflection; beta was sacroiliac joints or sacroiliac fracture vertical separation deflection; gamma was pubic symphysis separation/superior and inferior ramus of pubis fracture deflection; alpha beta gamma delta was compound floating damage. Proximal humerus joint damage variables: I was femoral head fracture; II was femoral neck fracture; II was intertrochanteric fractures of femur; IV was I to III compound fracture. The ABC damage variable positioning system for acetabular fracture was made up by the above-mentioned variables. The statistics from March 1997 to February 2010 showed 1122 cases acetabular fractures with 18 cases of double side acetabular fracture and 1140 cases of acetabular fractures. The pelvics anterior-posterior view, ilium and obturator oblique view, and 2/3D-CT materials were analyzed and researched.

RESULTSEach damage variables distribution situation in 1140 cases of acetabular fracture involved A in 237 cases (20.8%), B in 605 cases (53.1%), C in 298 cases (26.1%);front column fracture in 808 cases(70.9%), dome fracture in 507 cases (44.5%), posterior fracture in 1026 cases (90%). Acetabular variables: variabe 1 in 203 cases of simple displaced fracture (17.8%); variabe 2 in 516 cases of comminuted fracture(45.3%); variabe 3 in 421 cases of compression fracture (36.9%); 249 cases of pelvic ring lesions damage (21.8%), 75 cases femoral head fracture (6.6%); 18 cases of double side acetabular fracture and relative pelvic ring and proximal humerus joint variables (1.58%). Key part and curative effect elements of 1140 cases acetabular fracture: 507 cases of dome or posterior acetabular fracture (44.5%); 421 cases of compression fracture (36.9%); 249 cases of pelvic ring variables (21.8%); 75 cases of proximal humerus joint variables (6.6%); 486 cases of simple Aa/pl/2,Bapl/2 acetabular fracture (42.6% ).

CONCLUSIONCompression fracture, especially defected compression fracture, takes important part in acetabular damage variables, and also presents that acetabular fracture with pelvic ring and proximal femoral damage variables are not rare at all. The relationship of the acetabular fracture damage variables, and its percentage shows the key points and elements in clinical treatment: weight-bearing to dome accounts for 44.5%; compression to defects account for 36.9%, pelvic ring to float accounts for 21.8%; dome fracture to double side fracture account for 6.6%. The system has significant guiding effects on clinic in terms of evaluation of injury severity, anatomic localization, difficulty index, alternative strategy, operative approach, effect of treatment,and prognosis. And the most important thing is that the system creates the comparison of damage variables in same type of fracture and the communication of homo-language and explores a new method.

OBJECTIVE: To investigate the hidden blood loss and related risk factors of osteoporotic vertebral compression fractures after percutaneous kyphoplasty. METHODS: The clinical data of 153 patients with osteoporotic vertebral compression fractures who underwent percutaneous kyphoplasty from March 2015 to December 2017 were retrospectively analyzed, including 55 males and 98 females, aged 68 to 87(78.6±11.4) years old. Erythrocyte specific volume was collected before and after operation to calculate the hidden blood loss. The influence of sex, age, body mass index, bone mineral density, diabetes mellitus and hypertension, operation mode (unilateral or bilateral), operation time, operative segment and number, loss height of vertebral body and recovery height ratio on hidden blood loss was analyzed by multiple linear regression model. RESULTS: Postoperative hidden blood loss was (287.7±68.5) ml. Multivariate linear regression analysis showed that the history of diabetes mellitus (β=2.405, =0.012), the mode of operation(β=3.042, <0.001), the time of operation (β=2.043, =0.038), the operative segment (β=1.993, =0.043), the number (β=0.374, <0.001), the loss of vertebral height (β=2.785, =0.003) and the recovery ratio(β=7.301, <0.001) were correlated with occult hemorrhage. CONCLUSIONS There is a certain degree of occult hemorrhage in kyphoplasty for osteoporotic vertebral compression fractures. The risk factors of hidden hemorrhage are diabetes history, operation method, operation time, operative segment and number, loss of vertebral height and recovery ratio.
