Objective To establish the norms of Self-rated Health Measurement Scale Version 1. 0 ( SRHMS V1.0) for urban residents in Guangdong. Methods We used regional stratified random sampling method to select 6000 urban residents of 5 cities in Guangdong ( including Guangzhou, Maoming, Shantou, Shaoguan and Shenzhen) for a questionnaire investigation with SRHMS V1. 0, and establish the norms of mean,percentile and threshold based on characteristics of SRHMS V1.0 scores. Results The residents can be divided into 8 groups on the basis of gender and cut-off point of age 40,50 and 60. The mean norms of SRHMS V1.0 total scores were:(78.57±10.10),(76.93±9.90),(75.33±10.66),(69.45±13.90)for males under age40,40-50,50-60 and above 60 respectively;(77.03±10.00),(74.55±10.27),(72.24±11.76), (66.48±14.37)for females under age40,40-50,50-60 and above 60 respectively. The percentile norms of SRHMS V1.0 from 5 percent to 95 percent were established with 5% as interval. The norms of cutting off scores were established as five states according to the scores of TS,namely severe poor health,poor health,gen-eral health,good health and fairly good health,with( x-s),( x-0.5s),( x+0.5s),( x+s) as cutting off scores. Conclusion The study established the SRHMS V1.0 norms for urban residents of Guangdong preliminarily,which provides reference for further research of the population''s health status and its impacting factors.

OBJECTIVE:To establish the system of curriculum based on working process and occupation ability for pharmacy major in higher vocational colleges. METHODS:Investigation was conducted among medical practitioners from pharmaceutical companies,hospitals,pharmaceutical factories,scientific research institutions and other related professionals. RESULTS:150 ques-tionnaires were sent out,and 141 valid questionnaires were collected with effective recovery rate of 94.00%. Results of investiga-tion showed that respondents most valued graduates with interpersonal and communication skills,followed by professional skills and practical ability. They were mainly clinical application of drugs,pharmacological effects and adverse reactions of drugs in the pharmacology theory teaching,the mechanism of action of drugs were weakened. The ability of prescription distribution,symptoms inquiring and drugs recommending should be strengthened in the pharmacology theory practice teaching. More than half of the re-spondents thought that confirmatory tests were necessary to keep,which helped to train students’practical ability and deepen the understanding of the theory. Meanwhile,it was important to strengthen the students’communication with the patients or their fami-lies and doctors to cultivate the ability of acquiring professional knowledge. CONCLUSIONS:The investigation provides basis for the making of curriculum standards of pharmacology,through which teaching contents are selected,teaching methods are de-signed,and it makes the pharmacology course full of post applicability and provides better decision-making basis to meet the posi-tion requirements.

Objective To investigate the effect of interfering Hiwi gene on the apoptosis of MDA-MB-231 cells. Methods The mRNA and protein expression of Hiwi mRNA and its target protein were analyzed by qRT-PCR and Western Blot after transfection. MDA-MB-231 cells were divided into 6 groups according to the experimental design. Interference effects were screened as siRNA interference group (Hiwi10330 group), and then divided into 3 groups according to the experimental design: interference group, negative control group/NC, blank control group/Blank. The cell apoptosis rate was detected by flow cytometry after transfection. Results The expression of mRNA in the interference group was significantly lower than that in the siRNA group (P < 0.05), the expression of target protein of Hiwi gene was also significantly inhibited (P < 0.05). The apoptosis rate of MDA-MB-231 cells was significantly higher than that of NC and Blank groups (P<0.05). Conclusion The apoptosis rate of breast cancer cells MDA-MB-231 was significantly increased after siRNA targeting hiwi gene silencing.

Objective:To investigate the effects of HLA-B?1502 genetic polymorphism on cyclosporine( CsA)-induced liver injury in Chinese renal transplant recipients. Methods:HLA-B?1502 genotypes were determined by polymerase amplification chaln reaction of sequence-specific primers( PCR-SSP) in a total of 339 renal transplant recipients receiving CsA. All the subjects were divided into the CsA-induced liver injury group, non-CsA-induced liver injury group and the control group according to the liver injury occurrence. Results:In the 339 renal transplant recipients, the frequency of HLA-B?1502 mutation allele was 22. 64%. The distribution frequen-cy of HLA-B?1502 mutation allele had no significant difference among the three groups. There were no significant differences in the clinical characteristics of HLA-B?1502 genotypes among three groups(P>0. 05). Conclusion: No association is observed between HLA-B?1502 genetic polymorphism and cyclosporine-induced liver injury in Chinese renal transplant recipients.

Objective To assess the structure validity of application of sub-health measurement scale version 1.0(SHMS V1.0)in college students in Guangzhou City to lay a foundation for further analyzing the healthy status in this group and its influen-cing factors.Methods Nine hundreds college students were selected by adopting the stratified random sampling method for conduc-ting the questionnaire survey.The SPSS20.0 and AMOS21.0 were adopted to conduct the exploratory factor analysis(EFA)and confirmatory factor analysis(CFA)respectively.Results EFA obtained 7 factors with eigenvalue more than 1,the cumulative vari-ance contribution rate was 56.766%,moreover 7 factors were basically consistent with the theoretical structure of SHMS V 1.0. CFA conducted the model fitting for 3 total scales and 3 subscales,the results showed that the fitting of 3 subscales was good,the fitting result of total scale could be accepted,but did not reach the desired effect.Therefore,five times modification was applied in the total scale,and the fitting indexes after modification were CMIN/DF=2.723,GFI=0.907,IFI=0.917,TLI= 0.905,CFI=0.917,RMSEA=0.046,the fitting effect was comparatively excellent.Conclusion The dimension division of sub-health measure-ment scale is basically reasonable,and using this scale for measuring the sub-health status of college students in Guangzhou City has a better structure validity.

Objective:To investigate the feasibility of the surgical mode of immediate implant-based breast reconstruction (IIBR) with silicone implants under subcutaneous tissue directly after the total mastectomy in breast cancer.Methods:Data of 53 patients who underwent (skin-sparing mastectomy, SSM) or (nipple-areola-complex-sparing mastectomy, NSM) combined with IIBR in Department of Breast Surgery, Maoming People’s Hospital were retrospectively analyzed. Patients were divided into two groups, 31 cases with the silicone implant placed in different anatomical locations of the chest wall, including subcutaneous tissue, and 22 cases with subpectoral space implantation followed NSM or SSM. The two groups were compared in terms of the short-term and long-term complications, as well as the aesthetic outcome. Within 12 months the local recurrence rate was collected to evaluate the treatment safety of the two groups preserving the thickness of subcutaneous adipose after NSM or SSM.Results:There was no nipple-areola-complex (NAC) or skin flap for both groups, and the time of removing the drainage tube had no significant difference ( P>0.05) . There was no significant difference between the two groups in terms of the short-term complications within 6 months (repeated local infection and unknown effusion occurrence) , the long-term complications after 6 months (local skin with wrinkles sign, prosthesis displacement, and grade III-IV capsular contracture ( P>0.05) . However, the subcutaneous tissue implant group were superior ( P<0.05) in cosmetic outcome because of the breast had better symmetry. What’s more, no local tumor recurrence occurred in either group within 12 months. Conclusions:IIBR of subcutaneous tissue implantation (without patches) is an economical, novel, safe, and effective surgical mode for breast reconstruction, and the key to this operation mode depends on quality control of surgical procedures and the thickness of skin flap ≥ 1cm covering silicone implants. However, due to the cases enrolled in this study is not enough and short follow-up time, further clinical studies are still needed.

AIM: To compare the short-term postoperative visual acuity, visual disturbance phenomena, and spectacle independence rate in patients who underwent monocular implantation with trifocal, multifocal, or extended range of vision intraocular lens(IOL).METHODS: A retrospective analysis was conducted on 67 cataract patients(67 eyes)who underwent phacoemulsification cataract extraction combined with IOL implantation from March 2019 to December 2022. A total of 35 cases(35 eyes)received Symfony extended range of vision IOL implantation, 21 cases(21 eyes)received AcrySof IQ ReSTOR +3D multifocal IOL, and 11 cases(11 eyes)received AcrySof IQ PanOptix trifocal IOL. The preoperative uncorrected distance visual acuity(UDVA), uncorrected intermediate visual acuity(UIVA), and uncorrected near visual acuity(UNVA)and 3 mo postoperatively were documented. Moreover, defocus curves, visual disturbance phenomena, and spectacle independence rates were recorded at 3 mo postoperatively.RESULTS: At 3 mo postoperatively, no statistically significant differences were observed in UDVA among the three groups(P>0.05). A comparison of UIVA showed superior results in the Symfony and PanOptix groups compared to the ReSTOR group(all P<0.01). The UNVA of both the ReSTOR and PanOptix groups outperformed the Symfony group(all P<0.01). The defocus curves indicated that in the intermediate vision range(-1.00 to -1.50 D), the Symfony group exhibited better performance than the ReSTOR group(P<0.05); while in the near vision range(-2.50 to -3.50 D), the ReSTOR group was superior to the Symfony group(P<0.05). The PanOptix group demonstrated superior visual acuity in the near vision range(-2.00 to -3.50 D)compared to the Symfony group(P<0.05)and was also superior in the intermediate vision range(-1.00 to -2.00 D)compared to the ReSTOR group(P<0.05). No significant differences were observed in the incidence of glare or halo and binocular interference phenomena among the three groups(P>0.05). The PanOptix and ReSTOR groups exhibited a higher spectacle independence rate compared to the Symfony group(P<0.0167).CONCLUSION: Compared to Symfony extended range of vision IOL and ReSTOR multifocal IOL, PanOptix trifocal IOL offers a balanced approach to distance, intermediate, and near visual acuity, without a high incidence of glare and halo, and with a higher spectacle independence rate. Caution is still advised when considering monocular implantation with presbyopia-correcting IOLs.
