Objective:To compare the technique between concave distraction and convex resection in the treatment of congenital cervicothoracic scoliosis and evaluate its curative effect.Methods:Data of congenital cervicothoracic scoliosis patients from January 2010 to January 2020 were collected, among which 5 were males and 3 were females. The patients' age was 12.5±4.5 years old (range 6-20 years old). One case had C 7 wedged vertebra, 4 cases had T 1 hemivertebra and unbalanced vertebra, 2 cases had T 2 hemivertebra and 1 case had fused facet joint and wedged lamina in T 1. All patients had different degrees of vertebra fusion. Convex resection technique (one stage anterior and posterior combined hemivertebrae resection and annular osteotomy) was used to treat 4 cases before 2015; Concave distraction technique (A combination of anterior and posterior release, intervertebral space and facet space distraction, cage placed and fusion) was used to treat 4 cases after 2015 and 2 of them had 2 segments distraction. Perioperative neurological, vascular and wound related complications were recorded. The main parameters were structure Cobb angle, cephalic and caudal compensatory Cobb angle, mandibular incline, neck tilt, shoulder balance and head shift were measured pre-operation, post-operation and at the last follow-up. Results:All patients' surgeries were completed successfully. In convex resection group, the duration of surgery was 201±100 min (range 113-300 min) per vertebra, the estimated blood loss was 294±153 ml (range 100-450 ml) per vertebra, the hospital stay was 14±3 d (range 11-18 d) and follow up time was 51±11 months (range 36-60 months). In concave distraction group, the duration of surgery was 117±14 min (range 101-129 min) per vertebra, the estimated blood loss was 119±36 ml (range 85-167 ml) per vertebra, hospital stay was 17±3 d (range 14-20 d) and follow up time was 28±21 months (range 12-60 months). Convex resection group had longer operation time and more blood loss per vertebra than concave distraction group. In convex resection group, structural Cobb angle was 45.1°±21.0° pre-operation and 22.7°±15.3° post-operation, which was corrected significantly ( Z=6.53, P=0.038). The correction rate was 54.8%±30.9%. Cephalic compensatory Cobb angle was 22.1°±8.2° pre-operation and 8.2°±5.8° post-operation, which was corrected significantly ( F=6.01, P=0.049). The correction rate was 66.8%±15.1%. Mandible incline was 7.8°±3.1° pre-operation and 3.5°±1.5° post-operation, which was corrected significantly ( F=8.02, P=0.018). The correction rate was 51.0%±29.7%. In concave distraction group, structural Cobb angle was 32.2°±27.2° pre-operation and 16.3°±16.7° post-operation, which was corrected significantly ( F=7.43, P=0.024) . The correction rate was 59.0%±24.7%. Caudal compensatory Cobb angle was 18.9°(17.2°, 32.1°) pre-operation and 9.5°±10.3° post-operation, which was corrected significantly ( Z=6.00, P=0.049). The correction rate was 64.0%±24.1%. Clavicle angle was 3.9°±2.3° pre-operation and 0.3°±0.4° post-operation, which was corrected significantly ( F=1.75, P=0.040). The correction rate was 97.0% (48.5%, 99.8%). There was no significant difference in the correction rate of all radiographic parameters between the two groups. At the last follow-up, the patients' appearance of head, neck and shoulder were improved compared with those before surgery. In convex resection group, 2 patients showed nerve root stimulation symptoms postoperatively on convex side. One patient developed C 5 nerve root palsy which weakened deltoid muscle and the other patients presented with reduced triceps muscle strength. In concave distraction group, one patient developed C 5 nerve root palsy on convex side. All these symptoms recovered by conservative treatment 3 months after operation. Conclusion:It is safe and effective to treat congenital cervicothoracic scoliosis with convex resection technique and concave distraction technique. The concave distraction technique has the advantages of more safety, less operating time, less blood loss and easier to perform and has a wider application prospect.

Objective:To explore the safety, feasibility, and short-term outcome ofdistraction on the concave side in the treatment of patients with congenital cervical scoliosis.Methods:Between August 2015 and December 2019, 11 patients with congenital cervical scoliosis underwent distraction technique on concave side, among which 5 were males and 6 were females. Age was 9.9±3.1 years old (range 6-16 years old). The primary cervical spine deformity was hemi-vertebra with different degrees of vertebra fusion. 7 cases were in C 3, 3 cases were in C 4 and 1 case was in C 5. Anterior-posterior combined approach was used. Firstly, discectomy and soft tissue release on concave side were made through anterior approach, then distraction on concave side and fusion with internal fixation were made through posterior approach and at last fixation and fusion in anterior approach were made. In this study we measured structure Cobb angle, compensatory Cobb angle, mandibular incline, shoulder balance and the angle difference of trapezius muscle preoperation and post operation. Perioperative neurological,vascular and wound related complicationswere recorded. Results:All patients' surgeries were completed successfully. Eight patients received single site distraction and 3 patients received distraction in two sites. The duration of surgery was 466±141 min (range 150-659 min), the estimated blood losswas 387±191 ml (range 100-660 ml) and follow up time was 12.2±9.5 months (range 3-24 months). Structural Cobb angle was 28.9°±13.1° pre-operation and 7.4°(3.0°, 27.7°) post-operation at 3 months, which was corrected significantly ( Z=-2.934, P=0.003). The correction rate was 58.1±26.1% (range 18.8%-97.6%). Structural Cobb angle was 13.2°±12.3°at 1 year post operation and had no significant difference compared with 3 months post operation ( t=1.960, P=0.107). Compensatory Cobb angle was 18.3°±6.1° pre-operation and 9.4°±7.3° post-operation at 3 months, which was corrected significantly ( t= 5.071, P<0.001) and the correction rate was 51.3%±28.3% (range 2.4%-94.7%). Compensatory Cobb angle was 8.9°±7.7° at 1 year follow up and was corrected significantly ( t=5.253, P=0.003) compared to 3 months after surgery and the correction rate was 61.4%±26.9%. Two patients developed C 5 nerve root dysfunction and 1 patient developed numbness on the index and middle fingers after surgery. All of them occurred on the concave side and recovered by conservative treatment. Conclusion:The application of distraction on the concave side in the treatment of congenitalcervical scoliosis is with good feasibility and clinical safety. Short-term follow-up showed excellent resultswith a promising future.

Objective To systematically review the nursing preventive interventions and their effects on venous thromboembolism (VTE) in ICU patients. Methods We searched PubMed, Cochrane Library, EMBASE, SCI, CINAHL, Science Direct, BM, CNKI, WanFang and VIP, to collect the randomized controlled trials of nursing prophylaxis on VTE in ICU patients. Results 57 studies were included, meta-analysis provided that: the incidence rates of VTE and bleeding between Intermittent Pneumatic Compression Devices(IPC) group and low molecular weightheparin group in severe trauma patients had no statistical significance (P=0.14); comparing with graduated compression stockings (GCS) only group, the incidence rates of deep vein thrombosis(DVT) were lower in combination with IPC and GCS group (P=0.003);comparing with routine nursing group, the incidence rates of VTE were lower in IPC group and GCS group (P<0.01), the blood flow velocity and the average velocity of venous flow in lower limbs were increased in IPC group (P<0.01). The results of descriptive analysis show that early comprehensive nursing interventions and corresponding nursing interventions after risk assessment can reduce the incidence of VTE in ICU. Conclusion According to the present projects, using IPC, GCS, adopting early comprehensive nursing interventions and giving corresponding nursing interventions after DVT risk assessment are the effective interventions on ICU VTE.

Objective: To investigate the safety and efficacy of the Weitan Waifu patch on the postsurgical gastroparesis syndrome (PGS) of gastrointestinal cancer. Methods: The multi-center, double-blind, randomized controlled trial was conducted with superiority design. Patients with PGS of gastrointestinal cancer diagnosed in 4 AAA hospitals and the abdominal symptom manifested as cold syndrome by Chinese local syndrome differentiation were recruited. These patients were randomly divided into two groups according to 1∶1 proportion. Placebo or Weitan Waifu patch was applied in control group or intervention group, respectively, based on the basic treatments, including nutrition support, gastrointestinal decompression, promoting gastric dynamics medicine.Two acupuncture points (Zhongwan and Shenque) were stuck with placebo in control group or patch in treatment group. The intervention course was 14 days or reached the effective standard. Results: From July 15, 2013 to Jun 3, 2015, 128 participants were recruited and 120 eligible cases were included in the full analysis set (FAS), and 60 cases in each group. 88 cases were included in the per-protocol set (PPS), including 45 cases in the treatment group and 43 cases in the control group. In the FAS, the clinical effective rate in the treatment group was 68.3%, significantly superior than 41.7% of the control group (P=0.003). The medium time of effective therapy in the treatment group was 8 days, significantly shorter than 10 days in the control group (P=0.017). In the FAS, 3 adverse events occurred in the treatment group, including mild to moderate decrustation, pruritus and nausea. The incidence rate of adverse events was 5.0% (3/60) and these symptoms were spontaneously remitted after drug withdrawal. No severe adverse events were observed in the control group. There was no significant difference between these two groups (P=0.244). Conclusion: Weitan Waifu patch is a safely and effectively therapeutic method for patients with PGS (cold syndrome) of gastroenterological cancer.

OBJECTIVETo investigate the effect of laparoscopic Roux-en-Y gastric bypass on the short-term immune function of type 2 diabetic patients and to explore the correlation between the immune regulatory effect and blood glucose control.

METHODSClinical data of 28 patients with type 2 diabetes mellitus who underwent laparoscopic Roux-en-Y gastric bypass surgery in our hospital during January 2014 to January 2015 were retrospectively collected. Fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), immunoglobulin (IgG, IgA, IgM), T lymphocytes CD3(+), killer T cells CD3(+)CD8(+), helper T cells CD3(+)CD4(+), natural killer(NK) cell subsets CD16(+),CD56(+) and B cell subsets CD19(+),CD45(+) levels were detected and compared between before and after surgery. Correlation of immunoglobulin and immune cell subsets with the level of FBG and HbA1c were examined.

RESULTSAfter operation, FBG and HbA1c decreased significantly from (5.78±1.15) mmol/L to (14.21±1.89) mmol/L, and (9.96±0.97)% to (6.87±0.69)%, respectively (all P<0.05), and immunoglobulin (IgG, IgA, IgM) increased significantly [IgG: from(9.41±1.23) g/L to (12.74±1.61) g/L, IgM: from (1.71±0.22) g/L to (2.43±0.39) g/L, IgA: from (1.25±0.26) g/L to (1.97±0.23) g/L, all P<0.05]. Besides, T lymphocytes CD3(+), killer T cells CD3(+)CD8(+) and B cell subsets CD19(+)CD45(+) elevated significantly as well [T lymphocytes CD3(+): from (55.3±3.8)% to (67.6±4.6)%, killer T cells CD3(+)CD8(+): from (15.6±5.3)% to (28.7±4.2)%, B cell subsets CD19(+)CD45(+): from (8.4±3.7)% to (18.1±4.1)%, respectively, all P <0.05]. There was no significant difference in the expression of helper T cells CD3(+)CD4(+) and natural killer cell subsets CD16(+)CD56(+) between pre-operation and post-operation(all P>0.05). Levels of immunoglobulin (IgG, IgA, IgM), CD4(+)/CD8(+) ratio and B cell subsets were negatively correlated with HbA1c and FBG levels (IgG with FBG: r=-0.865, IgA with FBG: r=-0.887, IgM with FBG: r=-0.902, CD4(+)/CD8(+) with FBG: r=-0.956, CD19(+)CD45(+) with FBG: r=-0.834; IgG with HbA1C: r=-0.859, IgA with HbA1C: r=-0.957, IgM with HbA1C: r=-0.843, CD4(+)/CD8(+) with HbA1C: r=-0.912, CD19(+)CD45(+) and HbA1C: r=-0.885, all P<0.05), but the proportion of NK cells was not significantly correlated with HbA1c and FBG (P>0.05).

CONCLUSIONSLaparoscopic Roux-en-Y gastric bypass has good effect on the immune function of patients with type 2 diabetes mellitus. Improvement of immune function is correlated with the control of FBG and HbA1c.
