For probing into therapeutic effect, action, and proper and effective administration way of Jiang Ni Fu Sheng Liquid for treatment of acute cerebral hemorrhage, 150 cases were assigned at random to two groups to receive different therapies. Integral of hyponeuria, change of disturbance of consciousness, change of blood pressure, CT and clinical therapeutic effect were observed before and after treatment in the two groups. Results showed that the therapeutic effect in the treated group was obviously superior to that in the control group, with a markedly effective rate of 51. 1% and an effective rate of 90. 0%. It is suggested that Jiang Ni Fu Sheng Liquid has the action of relieving disturbance of consciousness, promoting recovery of nervous function, keeping stability of blood pressure, accelerating absorption of cerebral hemorrage, alleviating cerebral edema and hemorrhage of digestive tract, and so on.

Objective:To compare the accuracy and timeliness of 3-lead electrocardiography (ECG) and pulse oximetry (POX) in neonatal heart rate (HR) monitoring after birth.Methods:This prospective study recruited 42 high-risk newborns with gestational age ≥37 weeks and birth weight >1 500 g who were born through cesarean section without resuscitation requirement in Xi'an People's Hospital (Xi'an Fourth Hospital) from October 2019 to August 2020. 3-lead ECG electrodes and POX sensors were attached to the neonates immediately after drying to continuously monitor the HR within 10 min after birth. All procedure was recorded by video camera, and data were independently analyzed by a clinician after the procedure was completed. Differences in time required to connect the devices, time to obtain a reliable HR and the interval between them, the time needed for obtaining a reliable HR after birth, the proportion of neonates with reliable HR obtained within 5 min after birth and the consistency in the reliable HR readings between the two devices were compared using Wilcoxon signed-rank test, McNemar test, Spearman's correlation coefficient, intraclass correlation coefficient or Bland-Altman bias analysis.Results:The median time required to connect POX and 3-lead ECG and to acquire a reliable HR were 13.0 s (10.0-17.0 s) vs 23.0 s (18.0-28.3 s) ( Z=-5.050, P<0.001), and 79.5 s (56.2-128.0 s) vs 11.0 s (10.0-13.3 s) ( Z=-5.646, P<0.001), respectively. The total time from the beginning of connecting the devices and birth to acquiring a reliable HR were both longer for POX than those for 3-lead ECG [92.0 s (71.3-139.0 s) vs 35.0 s (30.0-39.5 s), Z=-5.579, P<0.001; 110.5 s (85.8-153.5 s) vs 52.0 s (45.0-66.3 s), Z=-5.579, P<0.001]. Reliable HRs were obtained in 69.1% (29/42) and 2.4% (1/42) of the infants by 3-lead ECG and POX within 1 min after birth, respectively. The percentage of infants for obtaining a reliable HR detected by 3-lead ECG within 5 min after birth were more than those by POX, but with statistically significant differences only at the first 60 s, 90 s, 120 s and 150 s (all P<0.001). The median HRs obtained by 3-lead ECG and POX within 10 min after birth were 161 beats/min (147-175 beats/min) and 160 beats/min (146-176 beats/min), respectively ( r=0.966, P<0.001). The mean difference of HR detected by the two devices was 0.56 beats/min (95% CI:-4.3 to 5.4 beats/min). The intraclass correlation coefficient was 0.961, showing good internal consistency. Conclusions:Neonatal HR can be assessed accurately by 3-lead ECG within 1 min after birth, which is far earlier than that by POX. Therefore, 3-lead ECG can be an option for continuously HR monitor in neonatal resuscitation.

Background Bulbar conjunctiva tissue appears to be thinning,elasticity declined,tension reduced and fascia atrophied in conjunctivochalasis.Histopathological examination of conjunctivochalasis shows decrease of elastic fibers and melt of collagen fibers.But there are fewer studies on the ultrastructure of conjunctiva of conjunctivochalasis up to now.Objective This study was to investigate the ultrastructure change of conjunctiva tissue in conjunctivochalasis.Methods Five loose conjunctiva samples of conjunctivochalasis and 5 normal conjunctival tissue samples were collected and ultra-microstructure changes of these samples were observed under the transmission electron microscope.Results The number of fibroblasts in conjunctivochalasis lamina was progressively decreased.The shape of fibroblasts was long and fusiform.Somatic synapse was slim.Nucleus-cytoplasm ratio was increased.Disorder,scattered and broken of the collagen fibril were seen,and some areas were dissolved or lacunae.Normal conjunctival fibroblasts were oval or polygonal,with wieners and long somatic synapse,and intercellular matrix was full of collagen fibril and dense arranged fibers.Fibroblasts in fascia of eonjunctivochalasis were linear,and collagen fibril was seriously defected.Fascia fibroblasts of normal bulbar conjunctiva were spindleshaped and bigger than conjunctivochalasis fibroblasts.There were full of collagen fibrils in intercellular matrix.Conclusions The collagen fibril is decreased and fibroblast cells are degenerated in lamina and fascia of conjunctivochalasis.

AIM: To study the role of nitric oxide ( NO ) and γ-aminobutyric acid ( GABA) in the formation of amblyopia by establishing 2 different types of amblyopic models.METHODS:A total of 18 aged 3-week kittens were randomly divided into monocular deprivation, strabismus and normal groups. All types of amblyopia were developed in the experimental eyes that were detected by P-VEP 12wk later. The cats were killed and the immunocytochemistry staining method were applied to observe under the light microscope the changes of distribution and positive cells areas of NO and GABA across the amblyopic retinal, compared to that from the normal cats of identical age.
RESULTS: The P-VEP showed that the amplitude of wave P1 was lower (P<0. 05) and the P1 latent time was longer ( P<0. 05 ) in two types of amblyopic cats than those in the normal cats. Compared to the normal cats, the NO and GABA positive cells areas were obviously reduced ( P<0. 05 ) across the retina in the amblyopic cats. But no significant difference was found between two kinds of amblyopic cats.
CONCLUSION:The NO and GABA play an important role in the formation of amblyopia in the level of retinal.

Genomic DNA was extracted from the blood samples of 3 patients from 1 pedigree with congenital nephrogenie diabetes insipidus (NDI) and their 12 family members.The whole coding region of the arginine vasopressin receptor 2 (AVPR2) gene was amplified by PCR and then directly sequenced,A mutation of AVPR2 gene [g1236T→C (L292P)]was found in 3 patients.The patients' mothers were found to have both mutant and normal alleles.

Objective To assess the diagnostic value of anti-cyclic citrullinated peptide antibody(an- ti-CCP),rheumatoid factor,anti-perinuclear factor(APF)and anti-keratin antibody(AKA)for juvenile rheumatoid arthritis(JRA)and compare it with rheumatoid arthritis(RA).Methods Anti-CCP was determined by ELISA in 54 serum samples of JRA patients,31 from patients with other rheumatic diseases and 116 RA patients.RF was determined in the same samples by latex agglutination test.APF and AKA were determined by indirect immunofluorescent assay.Results The sensitivity of anti-CCP,RF,APF and AKA was 61.1%, 57.4%,37.0% and 18.5% and their specificity was 96.8%,93.6%,96.8% and 100%,respectively for the diag- nosis of JRA.The sensitivity of anti-CCP resembleed that of RF,Anti-CCP was more sensitivity than APF and AKA in JRA.The sensitivity of anti-CCP,RF,APF and AKA was 82.3%,78.3%,48.7% and 25.4% and their specificity was 95.7%,73.7%,91.6%,94.0% respectively,for the diagnosis of RA.Anti-CCP,RF,APF and AKA were less sensitive in JRA than in RA.There was no statistical significance in specificity of these anti- bodies for the diagnosis of JRA and RA.Conclusion The detection of anti-CCP,RF,APF and AKA are use- ful for the diagnosis of JRA,but are less sensitive than in adults RA.

In order to develop a rapid detection kit for novel avian influenza virus (AIV) subtype H7N9, two sets of specific primers and probes were designed based on the nucleotide sequences of hemagglutinin antigen (HA) and neuraminidase antigen (NA) of novel H7N9 virus (2013) available in GenBank to establish the method of TaqMan probe-based multiplex real-time RT-PCR for rapid detection of AIV subtype H7N9. The primer and probe of HA were for all H7 subtype AIVs, while the primer and probe of NA were only for novel N9 subtype AIVs. The results showed that this method had high sensitivity and specificity. This method was applicable to the testing of positive standard sample with a minimum concentration of 10 copies/microL; it not only distinguished H7 subtype from H1, H3, H5, H6, and H9 subtypes, but also distinguished novel N9 subtype from traditional N9 subtype. A total of 2700 samples from Zhuhai, China were tested by this method, and the results were as expected. For the advantages of sensitivity and specificity, the method holds promise for wide application.

AIM: To observe thickness and morphological changes of bulbar conjunctiva pre- and post epidemic hemorrhagic conjunctivitis ( EHC ) therapy by optical coherence tomography ( OCT) .
METHODS: Observed morphological changes and measured the bulbar conjunctiva thicknesses of 29 cases (36 eyes) of incipient (1-2d) EHC patients, who were received and treated by department of ophthalmology, the Putuo Affiliated Hospital of Shanghai University of Traditional Chinese Medicine from May 2013 to December 2013, by OCT. Then measured the thickness again on 7, 14d after the therapy.
RESULTS: Among 29 patients (36 eyes), 7d after the EHC therapy, in 27 cured eyes, the full-thickness ( before 344. 00±59. 91μm, after 230. 19±22. 16μm, t=11. 75, P<0-01); epithelial thickness ( before 56. 52±6. 19μm, after 51. 37±5. 53μm, t=4. 61, P<0. 01); and stromal thickness (before 287. 11±60. 56μm, after 178. 81±20. 20μm, t=10. 69, P<0. 01) of patients' bulbar conjunctiva were thicker than values measured after therapy with significant difference. Significant difference was also found for full-thickness ( before 361. 39±65. 56μm, after 233. 44±22. 57μm, the difference was statistically significant, t=14. 45, P<0. 01);epithelial thickness ( before 55. 50±6. 72μm, after 46. 67±5-24μm, t=10. 06, P<0. 01) and stromal thickness ( before 305. 61±66. 02μm, after 186. 78±21. 82μm, t=13. 11, P<0-01 ) of patients' bulbar conjunctiva between values measured before and 14d after therapy.
CONCLUSION: The OCT is able to measure the thickness of bulbar conjunctiva in EHC patients. An significant increase was found in full, epithelial and stromal thickness of EHC patients' bulbar conjunctiva. With recovery from the disease, subepithelial fluid, interlaminar fluid and edema of the bulbar conjunctival stroma faded away firstly, which provide references for clinical therapies of the EHC.
