Objective To observe the effect of proprioceptive neuromuscular facilitation (PNF) and acupuncture on intractable facial paralysis. Methods 60 cases with intractable facial paralysis were divided into the acupuncture group and PNF and acupuncture group ( 30 cases respectively). They were assessed with the Portmann's Simple Scale after treatment. Results The score of the Portmann's Simple Scale in PNF and acupuncture group was higher than that in the acupuncture group (P<0.05).Conclusion PNF is synergistic to the effect of acupuncture on intractable facial paralysis.

Complex clinical situation requires healthcare providers to be able to perceive, un-derstand and predict the situation changes correctly, namely they need situation awareness. Good clin-ical situational awareness can help clinical decision-making and cooperation, which is critical to im-proving the quality of healthcare. Therefore this review aims to summarize the meaning, applications, status and influence factors, measurements and training of clinical situation awareness, to provide evidence for training and improving clinical situation awareness.

Objective To observe the changes of serum complements and proinflammatory cytokines in rats with sepsis, and to explore the possible mechanism.Methods 120 healthy male Wistar rats were randomly divided into three groups: normal control group (n = 15), sham operation group (n = 15) and sepsis group [cecum ligation and puncture (CLP) operation,n = 90]. The sepsis rats were sacrificed on 24, 48 and 72 hours after modeling. The level of serum complements (C5, C5a) and cytokines tumor necrosis factor-α (TNF-α), interleukin (IL-1, IL-6), high mobility group box 1 (HMGB1), macrophage migration inhibitory factor (MIF) were detected by enzyme linked immunosorbent assay (ELISA).Results Compared with normal control group and sham operation group, the levels of serum complements C5, C5a and IL-1β were significantly increased at 24 hours after CLP in sepsis group [C5 (ng/L): 1.60±0.19 vs. 1.04±0.20, 1.09±0.09; C5a (ng/L): 0.20±0.02 vs. 0.18±0.01, 0.18±0.02; IL-1β (ng/L): 700.20±111.41 vs. 475.87±108.96, 592.29±121.57; allP < 0.05]; then the levels of C5, C5a and IL-1β declined, the level of serum C5 were also higher than normal control group at 48 hours and 72 hours after CLP (ng/L: 1.17±0.24, 1.27±0.24 vs. 1.04±0.20, bothP < 0.05). In sepsis group the level of serum TNF-α (ng/L: 51.33±1.96, 51.06±1.64) was lower than that in normal control group (59.53±3.06) and sham operation group (57.91±2.72) at 48 hours and 72 hours (allP < 0.05). There was a time dependent rise of serum HMGB1 in sepsis group, which level was much higher than that in normal control group and sham operation group at 72 hours after CLP (ng/L: 472.21±20.94 vs. 406.00±43.16, 404.41±35.39, bothP < 0.05). There were no significant differences of MIF, and IL-6 level between groups at each time points.Conclusions Complement system led to uncontrolled inflammatory response and immune dysfunction through the release of proinflammatory cytokines and inflammatory mediators, which maybe one of the important mechanism of the pathology of sepsis.

Objective:To carry out experiential and service-learning social practice activities among nursing undergraduates, and evaluate the effects.Methods:From September to December 2020, 21 junior college students were recruited from School of Nursing of Fudan University. They carried out 3 social practice services of rehabilitation training for autistic children under the guidance of professional rehabilitation teachers from the social practice base for special children. The effects of social practice were evaluated by summative evaluation, questionnaire survey and focus group interview at the end of the activity.Results:The nursing students provided a total of 66 times of volunteer services for autistic children and other special children, with a total length of 132 hours within a month. The final evaluation score of nursing students was (92.10 ± 2.10) points, 9 (42.9%) nursing students had a very satisfied sense of achievement, and 20 (95.3%) nursing students had a high overall satisfaction with social practice activities. There were two themes of practice harvest and practice reflection, of which practice harvest included three sub-themes of changing disease cognition, enhancing learning initiative and enhancing humanistic care concept, and practice reflection included three sub-themes of carrying out personalized rehabilitation training, improving practical service quality and establishing effective service evaluation system.Conclusions:It is necessary to change education and teaching concept, strengthen practice base construction, innovate practice teaching mode, and combine theoretical knowledge, professional skills with social service, so as to promote students′ all-round development of morality, intelligence, physique, aesthetics and labor.

Aim To investigate the effect of gelsemium alkaloids on chloride channels and cell volume in he-patic carcinoma cells. Methods The time-lapse live cell imaging and whole-cell patch clamp techniques were used respectively to detect the volume changes and currents induced by gelsemium alkaloids in HepG2 cells. Results It was found that the cell volume was decreased by (12. 48 ± 2. 2) % (P<0. 01) when ex-posed to gelsemium alkaloids for 50 min and this phe-nomenon could be inhibited by the chloride channel blocker tamoxifen. It was shown by whole-cell patch clamping that a chloride current could be evoked by extracellular application of gelsemium alkaloids ( 2μmol·L-1 ) . The current was outward-rectified with-out obvious voltage- and time-dependent inactivation. The reversal potential of the current was ( -3. 21 ± 0. 67) mV ,which was close to the equilibrium poten-tial of chloride. The extracellular application of the chloride blockers, tamoxifen and 5-notro-2-(3-phenyl-propylamino)benzoic acid (NPPB), and 47% hyper-tonic solution inhibited the current significantly ( P <0. 01 ) . Conclusion Gelsemium alkaloids could acti-vate chloride channels and induce a volume decrease ( named apoptotic volume decrease, AVD) , and these effect could be inhibited by chloride channel blockers. The results suggest that the chloride channel can be one of the targets of gelsemium alkaloids in their anti-cancer action.

Objective To investigate the polymorphism of human cytomegalovirus（HCMV）UL146 gene in clinical strains,and to evaluate its clinical diagnostic and therapeutic value of gene.Methods The UL146 gene of clinical strains was examined by quantitative polymerase chain reaction（Q-PCR）or general polymerase chain reaction（PCR）.Positive samples of PCR amplification were sequenced and analyzed.Results High variability of UL146 gene was found among 28 HCMV strains.According to phylogenetic analysis,all sequences of UL146 in clinical strains could be divided into three types and four subtypes.Chemokine ELRCXC region was highly conserved in all sequences.Conclusion HCMV-UL146 genes showed a high degree of polymorphism,and its encoded chemokine ELRCXC region was highly con-served.The relationship between HCMV-UL146 gene′s polymorphism and different clinical symptoms of HCMV infection was unclear.

OBJECTIVETo assess the association between aggressive behaviors and 15 short tandem repeats (STRs) loci.

METHODSPeripheral blood samples from 541 army men with aggressive behaviors and 459 healthy individuals were collected. All sample were amplified with a AmpFlSTR Identifiler(TM) system and separated by electrophoresis to compare the genotypic and allelic frequencies of 15 STRs (CSF1PO, D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, FGA, THO1, TPOX and vWA) in the two groups.

RESULTSA significant difference was found in allelic and genotypic frequencies at loci D2S1338 and D19S433 (P< 0.01) between the two groups, but not for the remaining 13 STR loci (P> 0.05). Univarite analysis also showed a significant difference for allele 16, genotypes 19-22, 22-24 on D2S1338 and genotypes 13-14.2 on D19S433 between the two groups (P= 0.0018, P= 0.0001, P= 0.0003, P= 0.0000), with the OR values being 7.380 (95%CI: 1.701-32.028), 0.051(95%CI: 0.007-0.388), 13.933(95%CI: 1.845-105.717), 0.349 (95%CI: 0.216-0.564), respectively.

CONCLUSIOND2S1338 and D19S433 may be associated with aggressive behavior. Allele 16 and genotype 22-24 on D2S1338 may be susceptible factors for the disease, whilst genotypes 19-22 on D2S1338 and 13-14.2 on D19S433 may confer a protective effect on it.

Objectives To investigate the image quality,influencing factors and radiation doses of prospectively ECG-triggered spiral acquisition mode (Flash spiral mode)coronary computed tomography angiography (CCTA) using high-pitch dual-source CT in patients with different heart rates.Methods One hundred and thirty-four consecutive patients with mean heart rate (HR) ＞ 65 beats per minute (bpm) and ≤ 100 bpm were included in this study as group A using Flash spiral mode setting at 20％ -30％ of the R-R interval and 134 consecutive patients with mean HR ≤65 bpm were enrolled as group B using Flash spiral scan mode at 55％ of the R-R interval; 134 consecutive patients with mean HR ＞ 65 and≤100 bpm using spiral scan mode were included as group C. The image quality scores, effective radiation dose and influencing factors of image quality in three groups were assessed. All statistical analyses were performed using SPSS.Results (1)The non-diagnostic coronary artery segments in group A (28/1842,1.52％) were more than in group B (8/1819,0.44％ ) ( x2 =10.97,P =0.001 ) and there was no significant difference between group A and group C (32/1838,1.74％) ( x2 =0.280,P =0.345).The number of patients with non-diagnostic coronary segments in group A( 10/134,7.5 ％ )was more than in group B (2/134,1.5 ％,x2 =5.52,P =0.018 ),while there was no significant difference between group A and group C (9/134,6.7％,x2 =0.057,P =0.812).(2)The average heart rate variability (HRV) of patients with different image scores in the three groups wcrc significantly different. In group A,the HRV of score 1,2 and 3 were (2.29 ± 1.06),(5.17 ± 1.37),(8.88 ± 1.53) bpm,respectively (F =170.402,P =0.001 ).In group B were (2.26±1.01),(5.97 ±1.82),(12.00 ±9.64) bpm,respectively (F=95.843,P=0.001).In group C were (2.61 ±1.85),(7.90 ±3.97),(11.22 ±5.62) bpm,respectively (F=68.629,P=0.001 ). (3) The average effective radiation doses in groups A and B were significant lower than in group C [ A group was 1.04 ± 0.16,B group was 1.03 ± 0.16 and C group was 7.05 ± 1.05,t =65.5 ( A vs C),P ＜0.01 ( A vs C) ].Conclusions Flash spiral mode of high-pitch dual-source provides high image quality with significant reduction of radiation exposure in patients with HR ≤ 65 bpm. Patients with heart rates ＞65 bpm and ≤100 bpm without cardiac arrhythmia can perform CCTA using Flash spiral mode with image acquisition time setting at 20％-30％ of the R-R interval.

Aim To clarify the effect of Borneol on the chloride channels and cell volume in poorly differentia-ted nasopharyngeal carcinoma CNE-2Z cells.Methods The technique of whole-cell patch clamp was used to detect the chloride currents and analyze the character-istics of the currents in CNE-2Z cells.The volume changes caused by Borneol were measured by the meth-od of time-lapse live cell imaging.Results The chlo-ride currents were induced by extracellular application of Borneol (20 μmol·L -1 )isotonic condition.The currents showed a characteristic of outward rectification and did not show voltage-dependent or time-dependent inactivation.The reversal potential of the currents was close to the CI-equilibrium potential. The currents were inhibited by the chloride channel blocker tamox-ifen.The currents were also inhibited by 47% hyper-tonic solution.Borneol decreased the cell volume by 9.4% in 30 min.Tamoxifen completely inhibited the Borneol-induced cell volume decrease.Conclusion Borneol can activate volume-sensitive chloride channels and induce volume decrease in CNE-2Z cells.Chloride channels play a pivotal role in the process of volume decrease caused by Borneol.
