Objective:To understand the current situation of the demand for humanistic care of schizophrenics in convalescence and analyze the influencing factors, so as to provide the basis for clinical nurses to carry out targeted humanistic care for patients.Methods:A self-produced scale with a total score of 49-245 was used to investigate 516 convalescent period schizophrenic patients in 18 tertiary mental health institutions in 13 provinces of China, single factor analysis and multiple regression analysis were performed on their influencing factors.Results:The Likert 5-point scoring method was used. The overall score of the nursing care needs of hospitalized schizophrenic patients was (202.85±35.06) points, and the average score of total items were (4.14±0.16) points. Multiple linear regression results showed female ( B=0.100, P=0.024), stable marriage ( B=-0.098, P=0.026),high school (including secondary school) Education ( B=-0.107, P=0.018), family per capita monthly income of 2 000 yuan or above ( B=0.093, P=0.043),central region ( B=-0.110, P=0.014) were the main factors that affect the demand for humanistic care of inpatients with schizophrenia in convalescence. Conclusion:The hospitalized schizophrenic patients have higher and diversified needs for humanistic care. Patients with different genders, marital status, education level, monthly family income and living area have different needs for humanistic care. Individualized and standardized nursing should be given according to the actual situation of patients' needs to provide a more supportive environment for their rehabilitation.

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 compare the efficacy and safety of histamine H1 receptor antagonist loratadine with Leukotriene receptor antagonist Ibudilast in steroid resistant allergic rhinitis in a randomized controlled clinical trial.
METHOD:
Thirty-five cases were treated by Ibudilast, and 34 cases by loratadine. Score system was used to compare the therapeutic effect of these two drugs on clinical symptoms and signs.
RESULT:
Ibudilast shows a better curative effect than loratadine in the improvement of the total scores on clinical symptom and signs(P<0.05). Scores of symptoms and signs in Ibudilast group after 3, 7, 14 days decreased significantly by means of square analysis of single factor (P<0.01). No complication was observed.
CONCLUSION
Ibudilast can effectively alleviate the clinical symptoms and signs of steroid resistant allergic rhinitis with confirmed efficacy and safety, thus is recommended in steroid resistant allergic rhinitis. Increased doses or prolonged treatment of steroid is inappropriate.

OBJECTIVETo observe the clinical characteristics and short-term survival of patients with splenomegaly and acute-on-chronic liver failure related to chronic HBV infection.
METHODSElectronic medical records of patients with acute-on-chronic liver failure were collected to analyze the clinical parameters and 4-week survival of patients with or without splenomegaly.
RESULTSOf the 149 patients enrolled, the overall 28-day mortality rate was 48.3%, which was lower in patients with enlarged spleen than those without (34.2% vs 54.1%, P=0.034). Compared with patients without splenomegaly, patients with splenomegaly had lower platelet counts (P=0.001), lower ALT levels (P=0.005) and lower PT-INR (P=0.010). Although the occurrence of hepatic encephalopathy was comparable between patients with or without splenomegaly, severe conditions were more frequent in those without splenomegaly. Hepatic encephalopathy grades, serum creatinine levels, neutrophil percentages over 70%, PT-INR and splenomegaly were independent factors associated with the 28-day survival, and this novel model was superior to model of end-stage of liver disease in predicting the 4-week survival (P=0.017).
CONCLUSIONPatients with splenomegaly that evolves into acute-on-chronic liver failure have unique clinical characteristics and further clinical observations are warranted.

Objective To analyze the correlation between P73 gene G4C14-to-A4T14 double nucleotide polymorphism and the risk of lung cancer in Guangdong population. Methods Genotype analysis of P73 gene polymorphism in peripheral blood of 642 patients with lung cancers (including 450 NSCLC patients and 192 SCLC patients) and 354 normal controls was performed with HRM method (high-resolution fusion curve). Results HRM genotyping results showed that the distribution of P73 genotypes in 450 NSCLC patients was as follows: GC/GC 280 (62.3%), GC/AT 155 (34.4%), and AT/AT 15 (3.3%). P73 genotypes in 192 SCLC patients were 118 GC/GC (61.5%), 67 GC/AT (34.9%) and 7 AT/AT (3.6%). The P73 genotypes of 354 normal controls were 192 GC/GC (53.1%), 136 GC/AT (38.5%), and 26 AT/AT (8.4%). AT/AT homozygous genotypes significantly reduced the risk of NSCLC (OR=0.393;95% CI:0.037-0.873;P=0.001) and SCLC (OR=0.428;95%CI:0.050-0.880;P<0.001) compared with non-carriers. Conclusion The results of the present study indicated that the polymorphism of P73 G4C14-A4T14 may be a modification factor for the susceptibility of lung cancer in Guangdong province, and the increased GC content in the P73 gene may increase the risk of lung cancer.

Objective To analyze the epidemic characteristics and causes of post-exposure immunization failure of rabies in Hubei Province from 2015 to 2021, and to provide evidence for the prevention and control of rabies in Hubei Province. Methods The investigation data of rabies cases in Hubei Province from 2015 to 2021 were collected, and descriptive epidemiological methods were used for data analysis. Results A total of 127 cases of rabies were reported in Hubei Province from 2015 to 2021, with an average annual incidence of 0.31/million, showing a downward trend. The male to female ratio was 1.70:1. Farmers accounted for 82.67% of the total cases, and the 50-79 years old group accounted for 75.59%. The incidence was mainly concentrated in Xiangyang, Shiyan, Yichang and Jingmen, accounting for 77.17%. Most of the cases were concentrated in summer and autumn. Exposure of grade Ⅱand Ⅲ accounted for 24.79% and 75.21%, respectively. Hands, lower limbs below knee, head, arms and lower limbs above knee accounted for 46.15%, 25.21%, 9.40%, 8.55% and 7.69% of the exposed parts, respectively. Dogs, cats and wild animals accounted for 95.73%, 3.42% and 0.85% of the exposed animals, respectively. Stray animals, domesticated animals, neighbors' animals and wild animals accounted for 41.88%, 37.61%, 19.66% and 0.85% of animal sources, respectively. Neither the neighbors’ animals nor domesticated animals were vaccinated against veterinary rabies virus. After exposure, 8.55% of patients went to medical institutions for standard treatment of wounds, 9.40% were vaccinated with human rabies vaccine, and 4.55% of patients with grade III exposure were injected with rabies virus immunoglobulin. The incubation period within 6 months, from 6 months to 1 year, and over 1 year accounted for 72.22%, 14.74%, and 12.04%, respectively. The exposure degree (Z=-1.98, P < 0.05), exposure site (χ2=10.91, P < 0.05) and wound treatment (χ2=15.73, P < 0.05) had statistically significant effects on the incubation period. Among the 11 cases of post-exposure immunization failure, all were grade Ⅲ exposure, 63.63% were exposed to the head and face, 81.81% were not fully vaccinated with human rabies virus vaccine, 63.63% were not immunized with immunoglobulin, and 27.27% were inappropriate wound treatment. Conclusion The key to rabies prevention and control is to standardize dog management, strengthen rabies education, standardize post-exposure wound treatment, timely vaccinate against rabies virus, and inject rabies virus immunoglobulin when necessary.
