OBJECTIVETo compare the difference in the clinical efficacy on posterior circulation ischemia between acupuncture at stellate ganglion and conventional acupuncture as well as the impacts on blood pressure.

METHODSEighty cases of posterior circulation ischemia were randomized into an observation group (40 cases) and a control group (40 cases). In the observation group, acupuncture was applied to the bilateral stellate ganglions on the neck, stimulated with reinforcing technique by rotating the needles. In the control group, the acupuncture of reducing technique was applied to Fengchi (GB 20), Baihui (GV 20), Neiguan (PC 6) and Taichong (LR 3) in the excess syndrome. The even needling or reinforcing technique was applied to Fengchi (GB 20), Baihui (GV 20), Ganshu (BL 18), Shenshu (BL 23) and Zusanli (ST 36) for the deficiency syndrome. The treatment was given once every 3 days and 4 treatments were required totally in the two groups. The changes in total syndrome score, peak Systolic blood flow velocity (Vp) of vertebral artery and basilar artery, systolic and diastolic blood pressures were compared before and after treatment in the two groups. The clinical efficacy was compared between the two groups.

RESULTSThe total syndrome score was reduced apparently after treatment compared with that before treatment in the two groups (P < 0.01), and the reducing was more obvious in the observation group as compared with that in the control group (P < 0.01). The total effective rate was 87.5% (35/40) in the observation group, higher than 67.5% (27/40, P < 0.05) in the control group. After treatment, the reduced Vp of vertebral artery was not improved apparently as compared with that before treatment in the control group, Vp in blood velocity abnormality (including vascular spasm, stenosis or reduced velocity) of vertebral artery and basilar artery was all improved as compared with that before treatment in the two groups (P < 0.01), and the improvements in the observation group were more obvious than those in the control group (P < 0.01). After treatment, the systolic and diastolic pressures were reduced as compared with those before treatment in the two groups, and the reduced systolic and diastolic pressures in the observation group were more apparent than those in the control group (P < 0.01).

CONCLUSIONAcupuncture at stellate ganglion achieves the satisfactory efficacy in the treatment of posterior circulation ischemia and the significant efficacy of reducing blood pressure, more advanced than the conventional acupuncture.

OBJECTIVETo explore the feasibility of inducing human umbilical cord mesenchymal stem cells (HuMSCs) to differentiate into Leydig cells through conditioned medium derived from Leydig cells.

METHODSHuMSCs and Leydig cells were obtained by tissue blocks culture attachment and enzymatic digestion respectively. HuMSCs were induced by conditioned medium of Leydig cells as an experiment group while those before induction were cultured as a control group. The expressions of LHR, 3β-HSD and StAR in the induced HuMSCs were determined by RT-PCR after 3, 7 and 10 days of culture; those of CYP11A1, CYP17A1 and 3β-HSD measured by immunofluorescence staining after 2 weeks; and that of 3β-HSD detected by Western blot after 4 weeks.

RESULTSThe experimental group showed positively expressed LHR, 3β-HSD and StAR at 3, 7 and 10 days, CYP11A1, CYP17A1 and 3β-HSD at 2 weeks, and 3β-HSD at 4 weeks, while the control group revealed negative expressions at all the time points.

CONCLUSIONInduced with conditioned culture medium derived from Leydig cells, HuMSCs are likely to differentiate into steroidogenic cells and eventually into Leydig cells.

Objective To study the influence of fluoride on the expression of osteoprotegerin(OPG) mRNA and protein in suckling rat osteoblasts. Methods Osteoblasts obtained from calvarial of suckling Wistar rats were cultured in vitro in the media supplemented with NaF at a series of doses[O(control), 1,2 and 4 mg/L groups], and OPG mRNA expression and protein were evaluated by RT-PCR and ELISA methods, respectively. Results OPG mRNA expression in suckling rat osteoblasts cultured in vitro significantly increased after exposure to NaF for 48 h and 72 h(F=333.48,808.34,P<0.05). OPG mRNA expression in suckling rat osteoblasts cultured in vitro after exposure to NaF for 48 h at different doses(0.810±0.003, 0.819±0.031 and 0.870±0.044 for 1,2 and 4 mg/L groups, respectively) compared with that of control (0.800±0.040, all P<0.05). OPG mRNA expression further increased for 72 h exposure to NaF(0.933±0.047,1.031±0.051,1.240±0.062 for 1,2 and 4 mg/L, respectively), significantly higher than that of the control (0.805±0.020,all P<0.05) and corresponding groups at 48 h. NaF doses and time exposure exhibited a significant synergistic effect on OPG mRNA expression(F=2004.16, P<0.05). NaF also enhanced OPG protein expression in suckling rat osteoblasts cultured in vitro. Significant differences were observed only in 4 mg/L group(0.228±0.014,0.277±0.048) and control(0.205±0.012,0.229±0.010) at 48 h and 72 h (P<0.05). In addition, OPG protein expression at 72 h post-exposure was higher than that at 48 h,but there was no synergistic effect between concentration and time(F=1.21,P>0.05). Conclusions The results suggested that NaF could increase OPG mRNA and protein expression in suckling rat osteoblasts with a synergistic effect between the doses and exposure time.

OBJECTIVETo investigate reliability of FibroScan (FS) in diagnosing size of oesophageal varices (OV) in patients with liver cirrhosis.

METHODSA total of 260 patients with liver cirrhosis were enrolled in the study. All patients underwent endoscopy to assess OV stage and FS to measure liver stiffness. Receiver operating characteristic (ROC) curves were generated to evaluate the diagnostic reliability of FS.

RESULTSThe FS values according to OV stage were 20.9 ± 10.3 kPa for patients without OV, 32.2 ± 13.5 kPa for patients with mild OV, 45.6 ± 18.3 kPa for patients with moderate OV, and 55.1 ± 15.6 kPa for patients with severe OV. Significant differences were found among the groups (P < 0.001) as well as between any two groups (t=6.574, 10.533, 13.247, 4.719, 7.072 and 2.171, P less than 0.05 respectively). ROC curves of FS for the diagnoses of patients with various OV stages showed the following:with vs. without OV, 0.824 (95% CI:77.5% to 87.4%); less than moderate vs. more than moderate OV, 0.849 (95% CI:79.6% to 90.2%); and less than severe vs. severe OV, 0.871 (95% CI:81.1% to 93.0%); the corresponding FS cut-off values were 22.8 kPa, 30.6 kPa, and 34.6 kPa.

CONCLUSIONLiver stiffness measurement by FibroScan allows prediction of the oesophageal varices stage in patients with liver cirrhosis.

Objective Radiological findings of very rare hemangioendotheliomas in the orbit have not been reported.Radiological findings on different imaging studies of four cases with hemangioendotheliomas in the orbit were described and the literature was reviewed so as to understand features of hemangioendotheliomas in the orbit.Methods CT and MR imaging findings of four cases with hemangioendotheliomas in the orbit confirmed by histopathology were analyzed retrospectively.Results A mass was found in the superotemporal quadrant in the anterior extraconal space of the orbit in three cases and in the inferonasal quadrant in one case. CT studies revealed a homogeneously ovoid tumor with benign remodeling of the adjacent bone in three cases and a homogeneously irregular mass without any bony change in one case.MR imaging showed a mass in the orbit that was mildly hypointense on T_1-weighted sequences and hyperintense on T_2-weighted images with areas of flow voids representing vessels within the peripheral portion of the tumor in four cases.All four patients demonstrated significant enhancement immediately after intravenous administration of contrast material and a type D time-signal intensity curve (TIC)pattern on MR dynamic contrast enhancement scanning.Conclusions Hemangioendotheliomas in the orbit appeared as a hypervascular tumor predominantly in the extraconal space with areas of flow voids within the tumor and early significant enhancement of the tumor after intravenous administration of contrast material.MR imaging is the best method in demonstration of features of hemangioendotheliomas in the orbit and in diagnosis of these tumors.

Objective To investigate the morphologic characteristics of gonococcal inflammation of paraurethral glands in males. Methods Eleven male patients with gonococcal inflammation of paraurethral glands were examined by both real-time ultrasound imaging (Siemens Acuson X300) and 3.0 T magnetic resonance imaging (MRI, Philips Achieva). Results High-frequency ultrasound imaging revealed tubular echoic areas with well-defined borders and smooth margins in all the patients. The inside of these tubular areas was weak-echoic. These tubular echoic areas were blind in one end, but open in the other end, and ran in parallel with the urethra. The mean lumen diameter was 1.1 ± 0.2 mm (range, 0.7 - 1.3 mm) , and the mean lumen length was 8.4 ± 0.6 mm (range, 7.0 - 12.0 mm). Anechoic liquid-filled areas were seen in the tubular echoic areas in two patients. Paraurethral ducts were not detected by 3.0 T MRI in these patients. Conclusions High-frequency ultrasound imaging can clearly show the morphologic characteristics of gonococcal inflammation of paraurethral glands in males, and provide valuable ultrasound images for surgery.

Objective:To compare the clinical outcomes between anatomical locking plate, proximal humerus internal locking system (PHILOS) and anatomical locking plate combined with suture anchors in the treatment of comminuted fractures of humeral greater tuberosity.Methods:A total of 33 comminuted fractures of humeral greater tuberosity were surgically treated from October 2016 to October 2021 at Department of Orthopedics, Tongji Hospital Affiliated to Tongji University. There were 20 males and 13 females, with an age of (53.5±13.6) years. They were assigned into 3 groups according to different internal fixation techniques. Group A of 12 cases was subjected to fixation with anatomical locking plate via the deltoid approach, group B of 10 cases subjected to fixation with PHILOS via the pectoralis major and the deltoid approaches and group C of 11 cases subjected to fixation with anatomical locking plate combined with suture anchors via the deltoid approach. The operation time, intraoperative blood loss, range of shoulder motion, Constant-Murley shoulder score, visual analogue scale (VAS) and postoperative complications were compared between the 3 groups.Results:The 3 groups were comparable because there was no significant difference between them in the general clinical data ( P>0.05). The follow-up duration for all patients was (14.5±4.1) months. All fractures got united at the last follow-up. In groups A, B and C, respectively, the operation time was (57.9±7.8), (73.0±7.1) and (63.6±9.5) min, and the intraoperative blood loss (41.7±18.9), (82.0±22.9) and (46.4±13.6) mL, showing significant differences between the 3 groups ( P<0.05). The operation time and intraoperative blood loss in groups A and C were significantly less than those in group B ( P< 0.05). At the last follow-up, in groups A, B and C, respectively, the shoulder abduction was 144.0°±7.7°, 138.7°±10.7° and 148.5°±6.2°, showing significant differences between the 3 groups ( P<0.05). Group C was significantly better than group B ( P<0.05). There was no statistically significant difference in the forward flexion, external rotation, or internal rotation of the shoulder joint between the 3 groups ( P>0.05). The Constant-Murley scores in groups A, B and C, respectively, were (90.4±5.7), (86.1±6.6) and (93.1±3.4) points, showing significant differences between the 3 groups ( P<0.05). Group C was significantly better than group B ( P<0.05). The VAS scores in groups A, B and C, respectively, were 1 (0, 2), 1 (0, 2), and 1 (0, 1) point, showing insignificant differences between the 3 groups ( P>0.05). Group A had 1 case of shoulder joint stiffness and 1 case of fracture re-displacement complicated with acromial impingement syndrome, group B 1 case of shoulder joint stiffness and 3 cases of fracture re-displacement, but group C no post-operative complication. Conclusions:In the treatment of comminuted fracture of humeral greater tuberosity, all the 3 internal fixation techniques can lead to fine clinical outcomes. Conventional PHILOS may lead to relatively large trauma and a high incidence of postoperative complications. The anatomical locking plate may result in fine functional recovery of the shoulder due to advantages of less invasion, shorter operation time and fewer postoperative complications than PHILOS. The anatomical locking plate combined with suture anchors may lead to the best shoulder functional recovery and the least complications.

Objective:To explore the status of self-management in young patients with refractory partial epilepsy (RPE) and analyze its influencing factors.Methods:From May 2018 to April 2021, convenient sampling was used to select 226 young patients with RPE admitted to Xuanwu Hospital of Capital Medical University as the study subject. The patients were investigated using the General Information Questionnaire, the Epilepsy Self-Management Scale (ESMS), the General Self-Efficacy Scale (GSES), the Self-Concept Scale, and the medical coping modes questionnaire (MCMQ). Pearson correlation was used to analyze the correlation between self-concept, self-efficacy, coping style, and self-management. Linear hierarchical regression was used to explore the influencing factors of self-management in young patients with RPE. A total of 226 questionnaires were distributed and 214 were recovered, with a recovery rate of 94.69%. Excluding questionnaires with regular responses and omissions exceeding 10%, 208 valid questionnaires were recovered, with a valid recovery rate of 97.20% (208/214) .Results:Among 208 young patients with RPE, the total ESMS score was (110.64±12.56). Gender, education level, work situation, monthly family income, self-efficacy, self-concept and medical coping modes were the influencing factors of self-management in young patients with RPE ( P<0.05) . Conclusions:Medical and nursing staffs should implement individualized and systematic self-management education programs for young patients with RPE based on their personal circumstances, combined with self-efficacy and self-concept, to improve the self-management of young patients with RPE.
