Objective To investigate how SDF-1α and c-MYC protein regulates TACRl-Tr expression. Methods c-myc shRNA vector was constructed, small interfering RNA was employed for silencing c-myc gene in MCF-7 breast cancer cell. SDF-1α neutralized antibody was used in c-myc+ cell group and c-myc- cell group, while other c-myc+ cell group and c-myc- cells group were cultured under normal condition. The mRNA level of TACRl-Tr was determined by real-time PCR. Results c-myc shRNA vector was constructed successfully, in the normal presence of SDF-la, the level of TACRl-Tr mRNA in c-myc- cell group were lower than that in c-myc+ cell group( P < 0.05). But in the presence of SDF-la neutralized antibody, TACRl-Tr mRNA level of c-myc- cell group was higher than that of c-myc+ cell group(P < 0.05). Conclusion In the normal culture condition, c-MYC protein may transactivate TACRl-Tr transcription in MCF-7 cell, in the presence of SDF-1α neutral antibody, c-MYC protein lost the activity of transactivating for TACRl-Tr transciption.

The experience of "Zhenjing Anshen" acupuncture method originally created by professor WANG Fuchun for treatment of insomnia was introduced in this paper. From aspects of insomnia pathogenesis, theoretical foundation, characteristics of acupoint selection, needing methods, needing time, etc., the experience of Professor WANG Fuchun for treatment of insomnia was explained. The "Zhenjing Anshen" acupuncture method proposed, for the first time, "new three layers" method of acupoint selection, including Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6). This method presents the principles of acupoint selection along meridian, acupoint selection based on essence-qi-spirit, harmony of yin and yang. The acupuncture manipulation is emphasized, and treating time (the period of the day from 3 pm to 5 pm) is focused on; acupoint selection is simple but essential, and acupoint combination is scientific, which receives notable therapeutic effect in clinic.

OBJECTIVETo investigate the early clinical effects and radiological outcome of dynamic cervical implant (DCI) internal fixation in treating cervical spondylosis, and evaluate its safety and efficiency.

METHODSFrom June 2009 to December 2011, 19 patients with cervical spondylosis correspond to the indication of DCI internal fixation in the study, including 5 cases of cervical spondylotic myelopathy and 14 cases of cervical spondylotic radiculopathy. There were 8 males and 11 females, aged from 35 to 54 years with a mean of 43.2 years. Pathological segments included C3,4 in 1 case, C4,5 in 6, C5,6 in 6, C6,7 in 4, C3,4 and C5,6, C6,7 in 2. All patients were treated with anterior discectomy and decompression and DCI internal fixation, meanwhile, 2 cases of them with anterior cervical corpectomy and fusion plate fixation. Clinical evaluation included Modified Japanese orthopedics association (mJOA), neck disability index (NDI), visual analogue scale (VAS) score and patient satisfaction index (PSI) at pre-operation and final follow-up. Radiographic evaluation included flexion/extension lateral view at operative level and adjacent segment. The adjacent level degeneration was analyzed according to Miyazaki classification on MRI images.

RESULTSAll patients were followed up from 12 to 42 months with an average of 19.8 months. Preoperative mJOA score was 13.6±1.1 and at final follow-up was 16.3±1.2 with improvement rate of 85.0%. Preoperative VAS,NDI was 6.6± 1.4, 17.1±7.4 and at final follow-up was 1.4±0.8, 6.1±3.9, respectively; there was statistical significance in all above-mentioned results between preoperative and final follow-up (P<0.05). Preoperative ROM at operation level was (7.6±1.9)° and final follow-up was (7.8+2.1)°; preoperative ROM at C2-C7 was (38.6±7.2)° and final follow-up was (39.9±6.4)°; there was no statistical significance in all above-mentioned results between preoperative and final follow-up (P>0.05). Preoperative DHI at operation level was (6.3±1.1) mm and final follow-up was (7.1±0.8) mm, there was statistical significance in DHI between preoperative and final follow-up (P<0.05). No heterotopic ossification was found. All patients followed up MRI, degeneration of 3 segments aggravated 1 degree in 38 adjacent segments, without clinical symptom.

CONCLUSIONTreatment of cervical spondylosis with dynamic cervical implant can got satisfactory outcome in early follow-up. Activity of operative segment obtain reservation in some degree. The incidence of adjacent segment degeneration is lower and no adjacent segment disease occur. Nevertheless a longer follow-up time should be needed to assess the long term functionality of the DCI and the influence on adjacent levels.

OBJECTIVETo summarize and analyze the compatibility laws for acupoint selection of acupuncture in treating diabetic gastroparasis (DGP) in modern literatures of clinical researches.

METHODSRetrieved were literatures related to treating DGP by acupuncture or acupuncture combined other therapies from PubMed, CNKI, and WF from 1982 to 2014. Analyzed were frequency of acupoint use, meridians selected acupoints belonged to, regions selected, association laws of selected compatible acupoints.

RESULTSRetrieved were 35 with compatibility frequencies more than 15 listed as follows: compatibility frequency of Zusanli (ST36) and Zhongwan (CV12) was 33 (94.29%); compatibility frequency of Zusanli (ST36) and Neiguan (PC6) was 23 (65.71%), compatibility frequency of Zhongwan (CV12) and Neiguan (PC6) was 22 (62.86%), compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Neiguan (PC6) was 22 (62.86%); compatibility frequency of Zusanli (ST36) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zhongwan (CV12) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Sanyinjiao (SP6) was 15 (42.86%). Meridians selected acupoints belonged to were sequenced as Foot Yangming Stomach channel, Ren channel, Foot Taiyang Bladder channel, and so on. Acupoints selected were mainly in lower limbs, chest and abdomen, waist and back. The compatibility of Zusanli (ST36) and Zhongwan (CV12) was the most often used with the highest frequency.

CONCLUSIONSThe compatibility laws for acupoint selection of acupuncture in treating DGP were mainly dominated as upper-lower selection, three regions selection, local selection, anterior-posterior selection. The compatibility laws for acupoint selection of acupuncture along meridians were mainly dominated as the convergence points and exterior-interior meridian points.

OBJECTIVETo explore the effect of Buyang Huanwu Decoction (BYHWD) and its disassembled recipes on rats' neurogenesis after focal cerebral ischemia and to investigate its underlying molecular mechanisms.

METHODSFocal cerebral ischemia model was induced by occlusion of the right middle cerebral artery for 90 min using the intraluminal filament model. Rats were divided into the sham-operation group, the model group, the BYHWD group, the qi supplementing group, and the blood activating group. Medication was performed by gastrogavage 24 h after ischemia for 14 successive days. 5-bromodeoxyuridine (BrdU) (at 50 mg/kg) was intraperitoneally injected, once per day for 14 successive days. The neurological function was assessed using modified neurological severity score (mNSS) and the corner test at day 1, 7, and 14 after ischemia. BrdU/Nestin, BrdU/NeuN, and BrdU/GFAP positive cells were examined by double immunofluorescence at day 14 after ischemia. The protein expression of brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF) were detected by Western blot at day 14 after ischemia.

RESULTSCompared with the model group, the score of mNSS and the frequency of turning right significantly decreased in the BYHWD group and the qi supplementing group (P < 0.01), the number of BrdU/Nestin in the subventricular zone of the lateral ventricle, and BrdU/ NeuN and BrdU/GFAP positive cells in the peripheral ischemic cortex increased (P < 0.05, P < 0.01), protein expression of BDNF and VEGF increased (P < 0.05, P < 0.01). In the qi supplementing group, there was no statistical difference in BrdU/GFAP. But there was no statistical difference in each index of the blood activating group (P > 0.05). Compared with BYHWD group, the number of BrdU/Nestin, BrdU/ NeuN, and BrdU/GFAP positive cells significantly decreased (P < 0.01), and the protein expression of BDNF and VEGF were significantly reduced in the qi supplementing group and the blood activating group (P < 0.01).

CONCLUSIONSBYHWD could significantly improve neurogenesis and neurological function recovery after focal cerebral ischemia in rats. Its mechanisms might be related to up-regulating protein expression of BDNF and VEGF. Drugs for qi supplementing and drugs for blood activating had synergistic effects.

OBJECTIVETo introduce an arthroscopic technique in managing recurrent dislocation of the patella and its clinical results.

METHODSSixteen patients with recurrent patellar dislocation were reviewed, including 3 males and 13 females. The average age was 17.6 years old (ranged from 14 to 32 years). The patients suffering from patellar sub-luxation averaged 18.5 months (ranged from 6 to 23 months)before operation. These patients were treated with lateral patellar retinacular release outside the synovial bursa of knee joint and medial patellofemoral ligament reconstruction using the semitendinosus tendon free autograft. The Lyshohm scores before and after operation were used to evaluate outcomes at the final follow-up.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 48 months, with an average of 12 months. There was no recurrence. The Q angle decreased from (16.4 ± 3.7)° to (10.1 ± 1.4)°; insall index decreased from 1.37 ± 0.25 to 1.28 ± 0.23; congruence angle decreased from (21.3 ± 2.6)° to (5.86 ± 2.23)°; Lysholm score improved from 76.1 ± 5.2 to 89.8 ± 4.1 at 6 months after operation.

CONCLUSIONCompared with conventional procedure, arthroscopic surgery for recurrent dislocation of the patella achieves excellent outcomes with minimum invasion.
