Professor XIE Qiang's Tihu Guanding needling method, a kind of acupuncture method which takes acupoints of the Conception Vessel as the primary and acupoints of the Governor Vessel as the secondary. Acupoints Lianquan (CV 23), Tiantu (CV 22), Qihai (CV 6), Zhongwan (CV 12), Baihui (GV 20) and Dazhui (GV 14) are adopted as the basic ones. Other points can be added according to various symptoms, for instance, Yingxiang (LI 20) and Yintang (GV 29) for rhinopathy, Tinggong (SI 19) and Yifeng (TE 17) for otopathy, Yan'an (Professor XIE's experience) and Shanglianquan (EX-HN 21) for pharyngopathy and Kaiyin 1 (Professor XIE's experience) and Kaiyin 2 (Professor XIE's experience) for laryngopathy. During the needle retention, rotation manipulation should be done every 5 min at Lianquan (CV 23). And the patient should be told to put the tip of one's tongue at the the palate as well as to do deep breathing to communicate the Conception Vessel and the Governor Vessel. Moxibustion is adopted at Yongquan (KI 1) to induce the up floating fire to mingmen (where the primary yang is stored). The therapeutic effect on treatment of persistent otorhinolaryngologic diseases with the above mentioned method is approve to be good.

Objective To observe the expression of leukocyte-function-associated antigen-1(LFA-1)immunoreaction in children with febrile seizures(FS),and explore the neuroimmunomodulation mechanisms in the pathogenesis of FS.Methods Adopting flow cytometry(FCM),the levels of LFA-1 contained in blood serum and peripheral blood mononuclear cells(PBMC)of 60 cases [simple FS(SFS)30 cases;complex FS(CFS)30 cases] with febrile convulsion were analyzed,and compared with those in a normal group(30 cases).Out of 60 children with FS group,the LFA-1 mRNA in 20 cases with SFS and 20 cases with CFS was analyzed,and LFA-1 mRNA in19 health children taken out from control group(30 cases)was analyzed.The real-time PCR was used to detect the expression of PBMC LFA-1 mRNA.Results The expression of LFA-1 in the surface of PBMC of the 3 groups,the highest LFA-1 level was in the SFS group(50.89?21.36),the lowest LFA-1 level was in the CFS group(34.35?11.45),and control group was(41.39?16.30).Significant differences were found in 3 groups(Pa

Objective To investigate the effect of human umbilical cord blood stem cells on flash visual evoked potentials (F-VEP) of the traumatic optic neuropathy rats.Methods Forty-eight Sprague-Dawley rats were randomly divided into an injury group (Group A) and 3 treatment groups (Groups B,C,and D).A traumatic optic neuropathy model was built in Group A,and the rats in Groups B,C,and D were injected with the neurotrophic factor,human umbilical cord blood stem cells,and the mixture of the neurotrophic factor and human umbilical cord blood stem cells,respectively.F-VEP was recorded in both eyes of rats at the 1st h,1st week,2nd week,3rd week,and 4th week after the optic nerve injury.Results At all time points,there were significant difference in the wave latency and amplitude between Group A and normal control eyes (P＜0.01).The differences of the wave latency and amplitude between Group A and Groups B,C,and D were statistically significant at various time points after the injury except for the wave latency at the 1st h post-operation (P＞0.05).The amplitude in Group D was higher while the latency was shorter than those of Group B at all time points since the 1st week (P＜0.05).The comparisons at the same point in the remaining treatment groups were not significantly different (P＞0.05).Conclusion The mixture of human umbilical cord blood stem cells and neurotrophic factor has a promotion effect for the recovery of F-VEP of optic nerve in traumatic optic neuropathy in rats to some degrees.

BackgroundOptic nerve injury lead to apoptosis of retinal ganglion cells ( RGCs ), and its mechanism of apoptosis is endoplasmic reticulum stress (ERS). So, decreasing of ERS may protect the injury of RGCs. ObjectiveThe present study was to investigate the mechanisms of endoplasmic reticulum stress(ERS) and the protective effects of human umbilical cord blood stem cells on partial optic nerve crush injury. MethodsThe optical nerves were crushed with a 40 g clip by holding for 60 seconds to establish the partial optical nerve injury model in the left eyes of 102 SPF SD rats,and 10 μl of mRNA and 10 μl of nerve growth factor were injected into the vitreous immediately after the establishment of the model. The morphological changes of retinal ganglion cells(RGCs) were examined under the light microscope after 3,7,14,21 and 28 days and the RGCs number was calculated. The apoptosis rates of RGCs were detected by the TUNEL technique after 3, 12,24,45,72 hours and 1 week. The expression levels of GRP78 mRNA and CHOP mRNA were detected by reverse transcription polymerase chain reation (RT-PCR). This procedure followed the Regulations for the Administration of Affair Concerning Experimental Animals by Hunan Provincial Science and Technology Committee.Results The number of RGCs was significantly decreased with the prolongation of time of optical nerve injury in the model injury group,whereas the number of RGCs in the human cord blood cells group was reduced at a slower rate( Ftime =20. 100,P =0. 007 ). At various time points after the injection of human cord blood cells, the survival of RGCs was evidently increased in comparison with the model group(P＜0. 01 ). The apoptosis rate of RGCs was considerably elevated with injury time prolongation both in the model group and human cord blood cells group,but no apoptosis was seen from 3-24 hours after operation,and only a small amount of apoptotic cells were found in the human cord blood cells group from 48 hours through 1 week than in the model group(P＜0. 01 ). In the human cord blood cells group,GRP78 mRNA level was significantly higher and the CHOP mRNA level was significantly lower than those in the injury group at identical time points(P＜0. 01 ). ConclusionsIn the rat optic nerve partial crush model,ERS induces the apoptosis of RGCs. Human umbilical cord blood stem cells can protect RGCs from ERS injury by inhibiting apoptosis.

We reported perioperative nursing care of a patient with autogenous frozen ovarian pelvic transplantation after cervical cancer radical hysterectomy.Nursing priorities included:preoperative multidisciplinary assessment of the patient,including assessment of physical condition,activity of frozen frozen ovarian tissue and appropriate recovery time,autologous transplantation site,psychological status,and corresponding nursing interventions were provided.Nurses cooperated with surgeons during frozen ovarian resuscitation and other related operations.Health education and discharge guidance were provided after surgery,and the patient was informed about the importance of revisit and self-monitoring.The surgery was successful and the patient was discharged 3 days after surgery.There was no significant change in endocrine levels during revisit one month after surgery,but the patient considered symptoms of menopause had alleviated.

Objective To investigate the genotype-phenotype correlation between TSC1 and TSC2 associated tuberous sclerosis complex(TSC).Methods Nineteen infants with TSC were enrolled in the study.Their clinical manifestations and mutations of TSC gene were analyzed by chip capturing and next-generation sequencing.Results Among the total of 19 patients with TSC,13 TSC2 mutations and 4 TSC1 mutations were detected.The ratio of TSC2/TSC1 mutation-positive cases was 3.4/1.Six mutations were novel.There were epilepsy in 10 cases carrying TSC2 mutations,including 4 cases (31％) with refractory to antiepileptic treatment,and 3 cases carrying TSC1 mutations,including 1 case (25 ％)with refractory to antiepileptic treatment.The incidence and severity (grade 2)of epilepsy,brain imaging were not different in TSC2 and TSC1 patients(P =0.480 7,0.462 2).Compared with clinical manifestations,incidence of mental retardation (grade 1 or grade 2) was higher in TSC2 patients (85 ％,11/13 cases) than TSC1 patients (50 ％,2/4 cases).Also,the incidence of moderate and severe mental retardation (grade 2) was higher in TSC2 patients (54％,7/13 cases) in comparison with TSC1 patients(25％,1/4 cases).Compared with the phenotype of TSC2 and TSC1 patients,the frequencies of skin,renal and cardiac lesions were significantly higher in TSC2 patients than TSC1 patients.Conclusions TSC2 mutation may be the prominent molecular pathogenesis in Han population with TSC.TSC2 patients have much profound muhisystemitc leisions than TSC1 patients,including mental retardation,epilepsy,facial angiofibromas and renal angiomyolipomas etc,which should be confirmed further in domestic multicenter and large samples.

Osteoarthritis (OA) is the main reason of joint pain and dysfunction in the elderly in China, and its incidence is increasing year by year. In addition to the joint peripheral osteophyte formation and degeneration of articular cartilage, in?flammation, as one of the dominant pathological changes in OA, is causing more and more attention. Pro-inflammatory cyto?kines (PIC) are important mediators of inflammation. The increased level of PIC in OA can lead to systemic and local inflam?mation, results in further destruction of many kinds of tissues in joint (such as cartilage), and accelerates the development of OA. Besides, the severity of inflammation is closely related to the clinical symptoms of OA. Therefore, it is important to un?derstand the role of PIC in the pathogenesis of OA. From the perspective of the relationship between pro-inflammatory fac?tors and OA and the molecular mechanism, this article reviews the research progress in this field, which provides new con?cepts for diagnose and treatment of OA.
