OBJECTIVETo explore the clinical effects of lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine ( Fuchunsan ) on the treatment of postburn hyperplastic scar.

METHODSSixty-three patients with hyperplastic scar after burn injury hospitalized from February 2012 to June 2014 in our department were treated with lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine (Fuchunsan). Patients were divided into early stage group (E, n = 35), middle stage group (M, n = 25), and late stage group ( L, n = 3) according to the formation time of scar, which was respectively 3 weeks to 3 months, longer than 3 months and less than or equal to 6 months, and 3 to 15 years in groups E, M, and L. The number of times of laser treatment of patients in each group was recorded. The degree of scar pain in patients of the three groups was assessed by the Numerical Rating Scale (NRS) before treatment and after treatment for 1, 2, and 3 times. The scar condition of patients in groups E and M was assessed by the Vancouver Scar Scale (VSS) before treatment and after treatment for 1, 3, and 5 times. Patients in group L did not receive VSS assessment but were evaluated by clinical observation only. Photos of scar in treating area were taken before treatment and after treatment for 3 and 5 times to evaluate the clinical effect. Data were processed with t test.

RESULTSPatients in groups E and M were treated with laser for (4.8 ± 1.1) and (7.7 ± 2.1) times respectively. In group L, the treatment was stopped in 2 patients after laser treatment for 5 times, and 1 patient received laser treatment for 12 times. The degree of pain in patients of groups E and M was alleviated significantly after treatment for one time, and the number of patients scoring 1-4 point(s) in NRS increased from 5 cases to 38 cases. After treatment for 2 and 3 times, the increase in the number of patients scoring 1-4 point (s) in NRS was on a small scale. Before treatment and after treatment for 1 time, VSS scores of patients in groups E and M were similar (with values respectively 0.641 and 0. 082, P values above 0. 05). After treatment for 3 and 5 times, VSS scores of patients in group E were respectively (9.2 ± 0.8) and (7.0 ± 1.1) points, which were significantly lower than those in group M [ (9.7 ± 1.0) and (8.2 ± 1.0) points, with values respectively -1.993 and -4.433 , P < 0.05 or P < 0.01]. After treatment for 3 times, the rate of improvement in appearance was respectively 88.6% (31/35) and 72.0% (18/25) in groups E and M, and it was respectively 100.0% (35/35) and 96.0% (24/25) after treatment for 5 times. No significant effect in appearance was found in the 3 patients in group L.

CONCLUSIONSEarly application of lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine (Fuchunsan) for the treatment of postburn hyperplastic scar is effective.

OBJECTIVETo study the biomechanical change of the craniovertebral junction in conditions of atlas assimilation.

METHODSMimics software was used to process CT data of the craniovertebral junction in a health adult to obtain the three-dimensional reconstruction and the cloudy points of C1, C2 and part of the occipital bone. Then the cloudy points were imported into the Abaqus 6. 8 software to establish the occipito-atlantoaxial finite element model in normal structure. According to the established model in normal structure, the model in conditions of atlas assimilation was set by changing the model parameters. Both models of normal structure and atlas assimilation were loaded with 1. 5 N . m static moment to simulate four motions of flexion, extension, lateral bending and axial rotation respectively. The movement characteristics,joint stress force and ligament deformation was analyzed.

RESULTSUnder 1. 5 N . m moment, in model of atlas assimilation the C1-C2 range of movement decreased from 13. 55° to 11.88° in flexion,increased from 13. 22° to 15. 24° in extension and from 4. 05° to 4. 23° in lateral bending and remained unchanged in axial rotation when compared with the normal model. In flexion movement, the contact force of the atlanto-dental joint increased from 1. 59 MPa to 3. 28 MPa and the deflection of apical ligament, tectorial membrane and alar ligament increased 129. 1%, 157. 6% and 75. 1% respectively when compared with the normal model.

CONCLUSIONSThe normal C1-C2 motion mode is destructed in conditions of atlas assimilation, leading to the changes of the range of movement,joint stress force and the ligament deformation at C1 C2 junction. The atlantoaxial instability will likely occur in flexion motion.

BACKGROUND: Metal implants have been extensively applied in joint arthoplasty, but the stress shielding effect caused by its high elastic modulus results in a series of complications, such as bone resorption, bone atrophy and prosthesis loosening. Carbon fiber-reinforced polyetheretherketone (CF-PEEK) composites are anisotropic and exhibit more advantages used for prosthesis due to its low elastic modulus and high intensity.OBJECTIVE: To investigate the blood compatibility of CF-PEEK composites, and compare the biomechanical properties after arthroplasty between CF-PEEK composites and Co-Cr-Mo used for femoral head prosthesis. METHODS: (1) The blood compatibility of CF-PEEK composites was evaluated through hemolysis test. (2) Femoral samples from eight fresh cadavers were collected and randomly divided into two groups, followed by subjected to CF-PEEK and Co-Cr-Mo prosthesis replacement, respectively. The displacement between the prosthesis and bone was measured under loading 200, 400, 600, 800 and 1000 N, and the torsional strength after arthroplasty was detected.RESULTS AND CONCLUSION: (1) The hemolysis rate of the CF-PEEK composites was 3.23% < 5%, which was in line with the national standards for biological evaluation of medical devices. (2) The micromovement in distal prosthesis was significantly less than that of proximal prosthesis under different loads in both two groups (P < 0.05). (3) The torsion angle under different loads in the CF-PEEK group was significantly less than that in the Co-Cr-Mo group (P < 0.05), and the torsion stiffness in the CF-PEEK group was significantly higher than that in the Co-Cr-Mo group (P < 0.05). (4) To conclude,the CF-PEEK composites possess good blood compatibility and stability, which can be used as a prosthesis material.

Objective To evaluate the value of positive 99Tcm-MIBI tumor imaging for thyroid cancer diagnosis. Methods Fifty four suspected thyroid cancer patients underwent 99Tcm-O4 and 99Tcm-MIBI combined imaging procedure. The imaging data were confirmed by pathological findings. Results All the 54 cases had single throid nodules, and 25 of which were pathologically malignant. Fifty two cases of nodules were detected by the 99Tcm O4 thyroid static imaging, including 2 hot nodules,4 warm nodules, 10 cool nodules and 36 cold nodules;2 cases were negative by the imaging. Of the 25 malignant thyroid nodules, 16 nodules were visible by 99Tcm-MIBI uptake and were cold nodules;29 exhibited benign thyroid nodules,of which 15 could be seen by 99Tcm-MIBI uptake,including 1 warm nodules,2 cool nodules and 12 cold nodules. The sensitivity, specificity of the combined imaging of 99Tcm O4 and 99Tcm-MIBI were 64. 00% ( 16/25 ) and 48. 28% (14/29). No significant difference was found for the positivity between benign nodules and malignancy nodules by 99Tcm-MIBI tumor imaging ( χ2 = 0. 83, P ＞ 0. 05 ). Conclusion 99Tcm-MIBI tumor imaging is not specific for the diagnosis of thyroid malignancy.

OBJECTIVETo observe the efficacy and safety of Qizhi Jiangtang Capsule (QJC) in treating stage 3b diabetic kidney disease (DKD) patients with macroalbuminuria.

METHODSPatients who conformed to the diagnostic criteria of stage 3b DKD were randomly assigned to two groups according to random digital table, the experiment group and the control group, 84 in each group. All patients received a two-week elution period, and then were treated with basic Western therapy. Patients in the experiment group took QJC, 5 pills per time, 3 times a day, while those in the control group took Valsartan Capsule 160 mg each time, once daily. The observation period of follow-ups was limited within 6 months, and the time points were set as the baseline, 1st month, 3rd month, and 6th month. Systolic blood pressure (SBP), diastolic blood pressure (DBS), 24 h urine protein quantitative (24 h UPQ), plasma albumin (ALB), and serum creatinine (SCr) were detected and recorded, and estimated glomerular filtration rate (eGFR) was calculated. The occurrence of hypoglycemic reaction, coagulation disorder, gastrointestinal tract reaction, allergy, hyperkalemia, doubling of creatinine, and overall adverse events were observed and recorded at same time.

RESULTSFinally 81 patients in the experiment group and 80 patients in the control group were effectively included. Compared with the baseline level, SBP and DBS obviously decreased in the control group at month 1 of treatment (P < 0.05), and more significantly decreased at month 6 of treatment (P < 0.01). SBP at month 1, 3, and 6 of follow-ups; DBS at month 6 of follow-ups was lower in the control group than in the experiment group (P < 0.05). At month 1, 3, and 6 of follow-ups, 24 h UPQ of the experiment group was significantly lower than the baseline level (P < 0.01). It was also significantly lower than the level of the control group at the same time point (P < 0.05). There was no significant difference in 24 h UPQ at month 1, 3, and 6 of follow-ups between the control group and the baseline level (P > 0.05). ALB of the experiment group showed an increasing trend. It was significantly higher than the baseline level at month 6 (P < 0.05), which was also higher than that of the control group at same period (P < 0.05). There was no significant difference in the ALB level in the control group (P > 0.05). SCr of two groups showed an increasing trend. SCr of the experiment group was significantly higher at month 1, 3, and 6 follow-ups than the baseline level (P < 0.05). But the increment of SCr was higher in the control group than in the experimental group, and obviously higher than the baseline levels (P < 0.05). eGFR of both groups showed a decreasing trend. The decrement was higher in the control group than in the experimental group (P < 0.05). The proportion of progression of renal functions at month 1, 3, and 6 of follow-ups in the experimental group was 0.0% (0 case), 9.55% (8 cases), and 21.4% (18 cases), while they were 8.3% (7 cases), 21.4% (18 cases), and 40.5% (34 cases) in the control group. There was no statistical difference in the proportion of progression of renal functions between the two groups at month 3 and 6 of follow-ups (P < 0.05). There was no statistical difference in the incidence of adverse reactions between two groups (P > 0.05).

CONCLUSIONQJC could effectively reduce urinary protein of patients with stage 3b DKD, and delay the progression of renal functions.

OBJECTIVETo assess the efficacy and safety of Wuji Powder (WP) and a small dose aripiprazole in treatment of antipsychotic drug-induced phlegm dampness type amenorrhea.

METHODSSeventy female schizophrenic patients with antipsychotic drug-induced galactorrhea-amenorrhea syndrome (GAS) were recruited and randomly assigned to the treatment group and the control group, 35 in each group. All patients received antipsychotic drug therapy. Patients in the treatment group additionally took WP, while those in the control group took aripiprazole (at the daily dose of 5 mg, once daily). The therapeutic course for all was 4 weeks. Prolactin levels and obesity indices[body weight, waist aircumstance, body mass index (BMI) and waist-hit ratio (WHR)] were determined before and after treatment. The efficacy was evaluated.

RESULTSThe treatment course was completed in 95.71% of patients. The total effective rate of the 33 patients of the treatment group was 93.94% (31/33), while it was 91.18% (31/34) in the 34 patients of the control group. There was no difference in the total effective rate between the two groups (P > 0.05). Prolactin levels in both group after treatment were significantly lower than those of the baseline (P < 0.01). There was no significant difference in prolactin levels between the two groups after treatment (P > 0.05). Compared with before treatment, body weight, BMI, waist circumstance, and waist-hip ratio obviously decreased after treatment, showing significant difference when compared with the control group (P < 0.05). There was no significant difference in body weight, BMI, waist circumstance, and waist-hip ratio in the control group between before and after treatment (P > 0.05).

CONCLUSIONSBoth WP and aripiprazole could lower high prolactin levels of schizophrenics with phlegm dampness type amenorrhea. They showed equivalent efficacy. But WP showed more obvious effect in reducing obesity indices.
