OBJECTIVE: The purpose of this study was to compare efficacy, sonication energy efficiency, treatment time and safety of magnetic resonance-guided high-intensity focused ultrasound (MRgHIFU) and those of ultrasound-guided high-intensity focused ultrasound (USgHIFU) for ablation of uterine fibroids. MATERIALS AND METHODS: This study included 43 patients with 44 symptomatic uterine fibroids treated with MRgHIFU and 51 patients with 68 symptomatic uterine fibroids treated with USgHIFU. After therapy, contrast-enhanced MRI was conducted and complete ablation was defined as 100% non-perfused volume (NPV) of fibroids. Patients with completely ablated fibroids were selected for the comparison of the treatment data and sonication parameters between MRgHIFU and USgHIFU treated groups. RESULTS: Thirteen completely ablated fibroids in 10 patients (23.3%, 10/43) were achieved with MRgHIFU and 28 completely ablated fibroids in 22 patients (43.1%, 22/51) were achieved with USgHIFU. In completely ablated fibroids, the energy-efficiency factor (EEF) was 5.1 ± 3.0 J/mm3 and 4.7 ± 2.5 J/mm3 in the MRgHIFU and USgHIFU, respectively (p = 0.165). There was a negative linear correlation between EEF and the NPV of fibroids for MRgHIFU (p = 0.016) and USgHIFU (p = 0.001). The mean treatment time was 174.5 ± 42.2 minutes and 114.4 ± 39.2 minutes in the MRgHIFU and USgHIFU procedures, respectively (p = 0.021). There were no severe adverse events and major complications after treatment. CONCLUSION: MRgHIFU and USgHIFU are safe and effective with the equivalent energy efficiency for complete ablation of fibroids. USgHIFU has shorter treatment time than MRgHIFU.

OBJECTIVETo compare the therapeutic effects of aspiration via a directional soft tube and conservative treatment in patients with mild hemorrhage in the basal ganglion.
METHODSSeventy-five patients with mild cerebral hemorrhage (10~30 ml) were randomly divided into two groups for aspiration treatment with minimally invasive directional soft tube placement (minimally invasive group, n=36) and conservative treatment (medication group, n=39). The patients in the two groups had comparable mean GCS scores of 11-15 on admission. The clinical outcomes of the patients were compared between the two groups.
RESULTSIn the minimally invasive group, complete removal or absorption of the hematoma occurred within an average of 3.8 days, significantly shortened in comparison with the 24 days in the medication group. The short-term (1 month) follow-up of the patients showed good neurological recovery in 58% of the patients in the minimally invasive group, significantly greater than the rate of 29% in the medication group; 6 months after the treatment, good neurological recovery was achieved in 50% of the patients in the minimally invasive group, but only 16% in the medication. No death occurred in the minimally invasive group, and 2 patients died in the medication group. The cost of hospitalization averaged 5136.3 Yuan in the minimally invasive group and 11843.6 Yuan in the medication group.
CONCLUSIONCompared with conservative treatment, the minimally invasive treatment with soft tube placement can significantly shorten the hospital stay, promote neurological function recovery, lower the mortality rate, and reduce the cost of hospitalization.

An expression system is described for high-yield production of recombinant soluble human FasL (shFasL) in Dictyostelium discoideum cells. DNA encoding amino acids 141 - 281 of hFasL was PCR amplified from cDNA derived from activated human neutrophils. The resulting product was fused with a DNA fragment encoding hCG-beta signal peptide and cloned in the expression vector pMB12neo. Dictyostelium strain AX3 was transfected with this plasmid, yielding a recombinant strain called AX3-pCESFL95-H3. In order to improve the shFasL expression level, pMB12neo was optimized by replacing its transcriptional terminator/ polyadenylation segment of the 2H3 gene with an actin8 terminator/polyadenylation segment, yielding derived expression vector pMB74. The recombinant Dictyostelium strain called AX3-pLu8 was generated with this new plasmid. When the recombinant cells were cultivated in a complex HL-5C medium, a cell density of (1.5 - 2) x 10(7)/mL was reached, and the shFasL level expressed by strains AX3-pCESFL95-H3 and AX3-pLu8 was 23.5 microg/L and 206 microg/L, respectively. By using a newly developed synthetic medium called SIH as culture medium, higher cell density of (4 - 5) x 10(7)/mL was achieved. Correspondently, 111 microg/L and 420 microg/L shFasL were secreted by recombinant strains AX3-pCESFL95-H3 and AX3-pLu8, respectively.

OBJECTIVETo compare clinical results of treating Neer two- and three-part of proximal humeral fractures between anterolateral acromial approach and deltopectoral approach.
METHODSFrom January 2009 to December 2012, 49 patients with Neer two- and three-part of proximal humeral fractures were treated with locked plate fixation. In anterolateral acromial approach group, there were 22 patients including 9 males and 13 females with an average of (63.2±7.6) years old, while 27 patients in deltopectoral approach including 12 males and 15 females with an average of (62.9±7.0) years old. Operative time, blood loss during operation, fracture healing time and complications were observed and compared, postoperative Constant-Murley scoring and VAS scoring were applied for evaluate function of shoulder joint and pain at 3 months, 1 and 2 years respectively.
RESULTSAll patients were followed up from 24 to 41 months with an average of 34.5 months. Operative time, blood loss, fracture healing time in anterolateral acromial approach group was (68.20±7.04) min, (151.30±20.57) ml, (10.88±4.90) weeks respectively, and better than that of in deltopectoral approach group which was (75.81±13.70) min, (242.10±37.25) ml and (13.60±2.45) weeks. Three months after operation, Constant-Murley scoring and VAS score in anterolateral acromial approach group was 88.32±5.45, 0.41±0.63 and better that of in deltopectoral approach group which was 63.53±8.31, 1.65±1.02. There was no significant differences between two groups in Constant-Murley scoring and VAS score at 1 and 2 years after operation. Each group has one case occurred loss of length humerus head height, and there was 1 case with subacromial impingement, 1 case with bolt loose and 2 cases with delayed union in deltopectoral approach. No axillary nerve injury, humeral head necrosis and breakage of internal fixation occurred both of two groups.
CONCLUSIONBoth of anterolateral acromial approach and deltopectoral approach are effective in treating Neer two- and three-part of proximal humeral fractures, and can obtain excellent outcomes. Moreover, anterolateral acromial approach has advantage of less trauma, less blood loss, shorter operative time, rapid recovery of shoulder joint function and fracture.

OBJECTIVETo study the correlation of polymorphisms of CYP1A1 MSPI and glutathiones S-transferase (GST-M1) independently and in combination with the risk of lung cancer.
METHODSA case control study which included 91 cases of lung cancer and 138 controls collected from the First Affiliated Hospital of Sun Yat-sen University of Medical Sciences, Guangzhou Tumor Hospital and The Red Cross Hospital of Guangzhou or conmunity area. All subjects were investigated with a uniform questionnaire. Blood samples were collected from all cases and controls for detecting CYP1A1 MSPI and GST-M1 polymorphisms which were analyzed by PCR and RFLP.
RESULTSIt showed that there was no significant difference in frequencies of this genotypes of CYP1A1 MSPI between the two groups. The frequency of GST-M1 null (0/0) genotype was higher in the case group than in the control group, with an OR of 1.38 (95% CI 0.81 - 2.38), but there was no statistical significance. However, combination of several genotypes was strongly associated with lung cancer. There was a synergistic interaction between the m2m2 genotype of CYP1A1 MSPI and GST-M1 (0/0) genotype, with an OR of 2.47 (95% CI 1.03 - 5.90).
CONCLUSIONThe combination of two genetic polymorphisms significantly increases the risk of lung cancer.

OBJECTIVETo search for a better method for frozen shoulder due to cold damp.
METHODSSixty cases of frozen shoulder were randomly divided into an acupuncture-moxibustion group (32 cases) and an acupuncture group (28 cases). Acupuncture was applied mainly at Jianyu (LI 15), Jianliao (TE 14) and Jianzhen (SI 9) in either group. In acupuncture-moxibustion group, moxibustion on tender points was supplemented.
RESULTSIn acupuncture-moxibustion group, 7 cases were cured, 15 cases markedly effective, 9 cases improved and 1 case failed. The cured and markedly effective rate was 68.8% and the effective rate was 96.9%. In acupuncture group, 2 cases were cured, 9 cases markedly effective, 13 cases improved and 4 cases failed. The cured and markedly effective rate was 39.3% and the effective rate was 85.7%. The cured and markedly effective rate in acupuncture-moxibustion group was superior to that in acupuncture group (P < 0.05) and there was no significant difference in the effective rate statistically between two groups (P > 0.05).
CONCLUSIONThe clinical efficacy of acupuncture combined with moxibustion on tender points is superior to that of simple acupuncture on frozen shoulder due to cold damp.
