Objective:To investigate the current situation of telephone cardiopulmonary resuscitation (T-CPR) in China, and analyze the reasons for the low implementation rate of T-CPR.Methods:This was a multicenter cross-sectional survey. Twenty cities were selected from six geographical regions of China by convenient sampling method. Anonymous online electronic questionnaires were sent to emergency medical service staffs in each city. All respondents were divided into the routine T-CPR group and control group. Student's t test and Chi-square test were used to analyze the difference between groups. Multivariate logistic regression was used to analyze the influencing factors of T-CPR. Results:⑴A total of 1 191 questionnaires were collected. 80.94% of respondents knew T-CPR. Nine hundred and sixty respondents, who knew T-CPR and completed the questionnaires, were included in the study, and were divided into the routine T-CPR group ( n=401) and control group ( n=559). Nine hundred and thirty-nine (97.81%) responders believed that T-CPR should be implemented for cardiac arrest patients that could be confirmed by telephone.⑵Four hundred and one (41.77%) responders routinely implemented T-CPR. Among them, 237 (24.68%) responders always did and 164 (17.08%) responders often did. ⑶Multivariate logistic regression analysis showed that male ( OR=1.787, 95% CI: 1.235-2.587, P=0.002), age ( OR=1.025, 95% CI: 1.004-1.047, P=0.020), clinical medicine background ( OR=2.926, 95% CI: 1.387-6.171, P =0.005), dispatcher ( OR=5.305, 95% CI: 3.463-8.126, P<0.01), using medical priority dispatch system (MPDS) system ( OR=1.941, 95% CI: 1.418-2.656, P<0.01), and T-CPR policy or procedure ( OR=3.879, 95% CI: 2.652-5.674, P<0.01) were favorable factors for T-CPR. ⑷The top three reasons for implementing T-CPR in the routine T-CPR group were that they had received T-CPR training (67.08%), believed that T-CPR could improve survival rate (63.59%), and had standard T-CPR process (63.09%). The top three reasons for not implementing T-CPR in the control group were that worrying about bystander compliance (42.04%), worrying about the quality of bystander cardiopulmonary resuscitation (CPR) (38.28%), and worrying about medical dispute (36.14%). Conclusions:The awareness and implementation of T-CPR among emergency medical service staffs need to be improved. The implementation of T-CPR depend on telephone dispatchers with clinical medicine background, clear T-CPR policy, standardized operation procedure, and professional assistant tools. To improve the public's awareness of cardiac arrest and cardiopulmonary resuscitation, and to improve the supporting legal system are also conducive to the implementation of T-CPR.

BACKGROUND:The studies have shown that the mesenchymal stem cel s derived from bone marrow and umbilical cord can be continuously cultured in vitro, and maintain the characteristics of stem cel s. The mesenchymal stem cel s can differentiate into hepatocyte-like cel s after“cocktail”induction by various cytokines. OBJECTIVE:To further identify whether umbilical cord-derived mesenchymal stem cel s in vitro co-cultured with normal hepatocytes can differentiate into hepatocyte-like cel s, and to investigate the differentiation method. METHODS:Mesenchymal stem cel s were isolated from human umbilical cord with adherent method, and the surface markers of umbilical cord-derived mesenchymal stem cel s were detected with flow cytometry. The umbilical cord-derived mesenchymal stem cel s were co-cultured with liver LO2 cel s without adding exogenous inducers. The expressions of alpha-fetoprotein, albumin and human cytokeratin 19 mRNA of hepatocyte specific markers were detected with reverse transcription PCR at 7, 14 and 21 days after culture, and periodic acid-Schiff staining was used to identify the functions. RESULTS AND CONCLUSION:Mesenchymal stem cel s could isolated from human umbilical cord successful y, showing fibroblastic morphology and adherent cel characterization. Among these cel s, 96.02%cel s were CD29 positive cel s and 96.6%cel s were CD105 positive cel s. The percentage of CD34 negative cel s was 99.65%. The percentage of CD105+CD29+double positive cel s was 94.84%. The mRNA of alpha-fetoprotein was found on the 7th day after co-cultured with LO2 cel s, and the mRNA of albumin and human cytokeratin 19 were found on the 14th day. After co-cultured for 21 days, the alpha-fetoprotein mRNA could not be observed in the co-culture group. The expressions of albumin and human cytokeratin 19 were increased at 14 days. After co-cultured for 21 days, the glycogen staining was positive. Umbilical cord-derived mesenchymal stem cel s can differentiate into hepatocyte-like cel s after co-cultured with normal hepatocytes.

OBJECTIVE:
To study the effects of long term use of beclomethasone dipropionate (BDP) nasal spray on bone density with perennial allergic rhinitis (AR) in adults.
METHOD:
A 5-year randomized study was conducted on the effects of BDP nasal spray on serum calcium, phosphorus, alkaline phosphatase, and bone density determined before and after the treatment in 36 adult patients with perennial AR. 20-45 years of age, were randomly divided into 3 groups. That is group A (nasal spray 1 - <3 year), group B (nasal spray BDP 3 - <5 year) and group C (nasal spray BDP > or =5 year). The data were analyzed by paired t test.
RESULT:
The perennial AR were followed up for more than > or =1 year, > or =3 year and > or =5 year to observe the influences of nasal spray BDP. There were no significant difference between the data examined before and after the treatment (P > 0.05). Bone development is not influenced by nasal spray BDP < or =400 microg/d within 5 years.
CONCLUSION
Long term use of BDP nasal spray in adult patients does not lead to osteoporosis if the lowest effective steroid dose is given.

Objective:To investigate the effect of pelvic floor muscle exercise (PFMT) combined with transcutaneous electrical nerve stimulation (TENS) on urinary incontinence after radical prostatectomy.Methods:A total of 120 patients with urinary incontinence after radical prostatectomy in Shuguang Hospital, Shanghai University of Traditional Chinese Medicine from July 2020 to June 2021 were retrospective selected and divided into control group and observation groupthe according to different treatment method, 60 cases in each group. The control group was treated with PFMT, and the observation group was treated with PFMT combined with TENS. Urodynamic indexes of 72 h urine pad usage, maximum urine flow rate, maximum cystometric capacity, maximum urethral closure pressure, abdominal leakage point pressure, ICI-Q-SF score and the clinical efficacy were compared between the two groups. Measurement data were expressed as mean ± standard deviation ( ± s), and t-test was used for comparison between groups; Chi-square test was used for comparison of enumeration data between groups. Results:After treatment, the 72 h urine urine pad usage in the observation group [(1.95±1.13) pieces] was lower than that in the control group [(6.28±2.47) pieces], and the difference was statistically significant ( P<0.05). After treatment, the maximum flow rate [(13.92±2.53) mL/s], maximum cystometric capacity [(338.72±19.22) mL], maximum urethral closure pressure [(69.75±5.04) cmH 2O], abdominal leakage point pressure [(90.56±5.26) cmH 2O] in observation group after treatment were better than those in control group [(11.48±2.18) mL/s, (325.81±18.63) mL, (65.29±4.78) cmH 2O, (83.58±5.29) cmH 2O], the difference were statistically significant ( P<0.05). After treatment, the ICI-Q-SF score of the observation group [(5.97±1.82) points] was lower than that of the control group [(10.95±2.64) points], and the difference was statistically significant ( P<0.05); the clinical effective rate of observation group (93.33%) was higher than that of control group (78.33%), and the difference was statistically significant ( P<0.05). Conclusion:PFMT combined with TENS is better than PFMT alone in the treatment of postoperative urinary incontinence after radical prostatectomy.
