There is no significant relationship between corneal thickness and corneal curvature (K1, K2) in Kazak and the Han nationality college emmetropia students.

The clinical, neuroelectrophysiological, neuropathological characteristics and outcome of a case of acute sensory axonopathy are reported. The patient was a 32-year-old female. She presented with acute onset sensory abnormalities, sensory ataxia, pseudoathetosis and areflex. Lab testing showed cerebrospinal fluid albumin cytologic dissociation. Electromyography studies and sural nerve pathology were consistent with acute sensory axonopathy. Treatment including intravenous immunoglobulin and steroid therapy was provided. Her symptoms recovered slowly without relapse, so did tibial H-reflex amplitudes.

Objective To report the clinical and pathological features of chronic graft-versus-host disease-related polymyositis by summarizing the clinical data of the patient with chronic graft-versus-host disease-related polymyositis. Methods One patient with chronic graft-versus-host disease-related polymyositis was hospitalized in our hospital on December 29,2010.The patient,40 years old,female,underwent allogeneic haematopoietic stem cell transplantation because of acute granulocytic-monocytic leukemia.Fourteen months later she manifested as slowly progressive muscle weakness and myalgia in all limbs.Serum creatine kinase level was between 426-1948 U/L. Myositis antibody EJ was strongly positive.Electromyogram showed a neurogenic impairment and slow peripheral nerve conduction speed.Muscle biopsies were carried out in the left biceps brechii.In addition of standard histological and enzyme histochemical staining for the muscle sections,immunohistochemical workup was performed with mouse antiCDs,anti-CD20,anti-CD68 and anti major histocompatibility complex- Ⅰ ( MHC- Ⅰ ) monoclonal antibodies as first antibodies.Results The muscle biopsy showed large variation of fiber size,with muscle fiber necrosis,regeneration.Some angular fibers distributed in small cluster.The inflammatory cells infiltrated around the small vessel or in the endomysium,mainly CD8+ T-lymphocytes and CD6+8 macrophages.The most muscle fibers were MHC-Ⅰ positive. Conclusion The graft-versus-host disease-related polymyositis manifests as chronic myositis process with neurogenic lesions.

Objective To investigate the establishment and application effect of Evaluation Form for Cancer Pain Nursing Quality Control. Methods Nursing quality control team was founded on account of the leadership of the superintendent of nursing department and the head nurse from department of pain clinic. The team consisted of eight nurses containing the head nurse from model ward of the standardized treatment for cancer pain and nurses from department of pain clinic. According to the criteria and content of on- site assessment of cancer pain standardized treatment demonstration unit, indexes for cancer pain nursing quality was made, combining with the management practice of cancer pain nursing. The quality indexes was divided into five one- class indexes which had a total score of 100 and 20 for each including pain assessment, cancer pain treatment, patient education, nursing ability and others. Each one- class index followed with two - level index. And the table was applied to the cancer pain standardized treatment demonstration unit. Results After application of the Evaluation Form for Cancer Pain Nursing Quality Control, the following items were improved compared with those before application: accuracy of pain assessment [97.22%(70/72)vs.90.28%(65/72)], correctness of nursing record [98.61%(71/72)vs.88.89%(64/72)], satisfactory rate of pain control [97.22%(70/72)vs.84.72%(61/72)], accurate usage rate of cancer drugs [100.00%(72/72)vs.88.89%(64/72)] , understanding rate of health knowledge of patients and their family members[100.00%(72/72)vs.80.56%(58/72)], satisfactory degree of patients and their family members with nurses [100.00%(72/72)vs. 88.89%(64/72)], χ2=4.71, 8.87, 10.86, 8.87, 18.00, 8.87, P<0.05 or 0.01. Conclusions Application of Evaluation Form for Cancer Pain Nursing Quality Control in management of cancer pain can improve the nursing quality of cancer patients.

We report the management and maternal and neonatal outcomes of four cases of delayed interval delivery after cervical cerclage in twin pregnancies, who hospitalized in Shanghai First Maternity and Infant Hospital from year 2017 to 2018. Four patients with dichorionic diamniotic twin pregnancies all presented with gradually weakened uterine contractions after spontaneous vaginal delivery of twin 1. After informed consent, the patients received cervical cerclage at 2 to 3 days after delivery when the maternal and fetal conditions were stable, to delay delivery of twin 2. The gestational weeks at delivery of twin 1 were 25 +4, 23 +1, 27 +1, and 23 weeks, which were noted for 30 +1, 32 +6, 31 +4, and 24 weeks for twin 2, respectively. Delayed delivery intervals were 32, 69, 31 and 7 d. Three of the four twin 2 survived, with Apgar score ≥ 8 at 1 minute and birth weight of 1 390, 2 290 and 1 620 g. During a 2-year follow-up, no developmental abnormalities were observed in the children, and no serious maternal complications were found, including severe infection, bleeding or cervical laceration.

This study is to report the study of protective effects of myricitrin against oxidative stress-induced apoptosis of vascular endothelial cells and the investigation of the possible mechanisms of action of myricitrin. The model of H2O2-induced apoptosis of vascular endothelial cells was used to determine the protective effects of myricitrin. The levels of LDH, MDA and the activities of SOD, NO were measured using the respective kits. The H2O2-induced apoptosis of vascular endothelial cells was detected using MTT reduction, TUNEL assay, JC-1 and ROS staining. The activation of Caspase-3 was also measured by fluorometry. The expression of apoptosis-related proteins was determined with Western blotting assay. Myricitrin had significant protective effects against H2O2-induced apoptosis of vascular endothelial cells in a time- and dose-dependent manner. The results show that myricitrin could attenuate H2O2-induced decrease in the activities of SOD (P < 0.01). Myricitrin could decrease the levels of LDH, MDA and increase cell viability and the mitochondrial membrane potential (P < 0.01). Myricitrin had protective effects in a dose-dependent manner between 32 micromol x L(-1) to 64 micromol x L(-1). Myricitrin pretreatment could attenuate H2O2-induced increase of p-ERK. Moreover, myricitrin pretreatment could up-regulate the expression of the anti-apoptotic protein Bcl-2, down-regulate the expression of the pro-apoptotic protein Bax, and decrease the expression of Caspase-3, 9. In conclusion, myricitrin had significant protective effects against H2O2-induced apoptosis of vascular endothelial cells. Myricitrin can enhance the activities of anti-oxidative enzymes and decrease the production of free radicals. The possible mechanisms of action of myricitrin are due to myricitrin-mediated inhibition of phosphorylation of the apoptosis signaling pathways-related kinase ERK, up-regulation of the expression of the anti-apoptotic protein, and down-regulation of the expression of the pro-apoptotic protein.

This study was aimed to acquire the dynamic changes of chlorogenic acid and luteoloside of honeysuckle at different collecting periods in order to decide the best harvesting time of honeysuckle in Donghai County, Jiangsu Province. The content determination method used in the detection of chlorogenic acid and luteoloside of honeysuckle was from the 2010 edition of the Chinese Pharmacopoeia. The skills of HPLC fingerprint characteristic features, and the yield of pressed flowers were combined in the evaluation of honeysuckle at the three-green period, two-white pe-riod, great-white period, silver-flower period and the golden-flower period. The results showed that the content of honeysuckle at different blossoming stages had obvious changes in content of chlorogenic acid and luteoloside, as well as the pressed flower quality and yield of the flower. It was concluded that the optimal harvest time of honey-suckle was for the two-white period and the great-white period, which was consistent with the real origin.
