Objective To explore the indication,surgical procedure and the postoperative treatment of breast conserving modified radical mastectomy for early stage breast cancer .Methods The clinical data of 21 patients with early stage breast cancer underwent breast conserving modified radical mastectomy were analyzed retrospectively. Results All patient recovered uneventfully. All the external configuration of the breast were fine. There were no recurrence and no complications in this series. Conclusions The breast conserving modified radical mastectomy is recommended for the early stage breast cancer. The external configuration of breast is fine postoperatively, and patients have higher survival quality.But follow up is necessary in order to find and treat the recurrence of breast cancer.

Myocardial ischemia-reperfusion injury (MI/RI) is an inflammatory cascade process involving the interaction of multiple factors.In recent years,more and more evidence suggests that NOD-like receptor pyrin domain containing 3 (NLRP3) inflammasome,an important component of the innate immune system,is closely associated with the inflammatory damage of MI/RI.Furthermore,blockage of NLRP3 inflammasome or the release of its downstream pro-inflammatory cytokines may provide new therapeutic targets for this disorder.

Objective:To investigate the role of sterol regulatory element binding protein-1 (SREBP1) in atorvastatin-induced reduction of nucleotide-binding oligomerization domain-like receptor protein 1 ( NLRP1 ) inflammasome expression. Methods:THP-1 cells were treated with phorbol 12-myristate 13-acetate (160 nmol/L) for 12 h to be differentiated into macrophages. The medium was then replaced with serum-free medium containing lipopolysaccharide and ( or ) atorvastatin. The mRNA expression of NLRP1 and SREBP1 were detected by Real-time PCR. The protein expression of NLRP1 and SREBP1 were determined by Western blot. Furthermore, we observed the effect of SREBP1 siRNA on atorvastatin-induced reduction of NLRP1 expression. Results:Atorvastatin inhibited the mRNA and protein expression of NLRP1 and SREBP1 in the THP-1 macrophages. SREBP1 siRNA showed no significant difference on lowering NLRP1 expression when compared with atorvastatin. Treating cells with SREBP1 siRNA and atorvastatin at the same time resulted in more obvious reduction of NLRP1 expression than single use of SREBP1 siRNA or atorvastatin. Conclusion:Atorvastatin might exert anti-inflammatory effect by repressing NLRP1 expression through the SREBP1 path-way.
5.Effects of online learning on children's vision
Chinese Journal of Primary Medicine and Pharmacy 2022;29(2):267-270
Objective:To investigate the effects of online learning on children's vision. Methods We collected the vision data of children from the Huainan area recorded during December 1-31, 2019 (before online learning) and from December 31, 2020 to January 31, 2021 (after online learning) in Affiliated Ophthalmic Hospital of Anhui University of Science and Technology. These data were divided into three groups according to different age brackets: primary school (6-12 years, n = 1 124), middle school group (> 12-15 years, n = 552), and junior high group (> 15-18 years, n = 554). The change in vision after online learning relative to before online learning was analyzed using SPSS 22.0 software. Results Before online learning, the overall incidence of myopia was 52.70%, the incidence of myopia was 25.31% for 6-12 years old, 71.89% for > 12-15 years old, and 88.34% for > 15-18 years old. After online learning, the overall incidence of myopia was 62.40%, the incidence of myopia was 40.25% for 6-12 years old, 78.60% for > 12-15 years old, and 91.88% for > 15-18 years old. There were significant differences in the prevalence of myopia in each age bracket between before and after online learning ( χ2 = 21.44, P < 0.001). Conclusion Online learning greatly affects the vision of adolescents. Corresponding measures should be formulated to strengthen the prevention and control of myopia in children.

Objective To elucidate the molecular evolutional characteristics of HIV-1 non-nucleoside reverse transcriptase inhibitor (NNRTI) drug resistance-associated mutations in AIDS patients receiving highly active antiretroviral therapy (HAART).Methods Four AIDS patients receiving HAART with good adherence within a HlV-1 drug resistance cohort from a rural region in central China were selected,who possessed susceptible virus at the beginning of treatment and gradually came to produce resistance to NNRTIs during the process of antiretroviral therapy (ART),reverse transcriptase (RT) genes from each patient's peripheral blood samples (from 3 to 30 months after withdrawal) were cloned and sequenced in succession.Results To sequenced total 855 clones and obtained the HIV-1 NNRTI drug resistance-asseciated mutations patterns of the four patients: (1)G190A often appeared with F227 L and had the tendency of accumulating P236V during the process of treatmenL (2)Y188C always presented alone and sometimes it concured with P236V.(3) YI81C frequently concured with VI79D or KIO3N and the combination varies from patient to patient.(4)K103N often combined with Y181C or M230L Conclusions The molecular evolutional characteristics of HIV-1 NNRTI drug resistance-asseciated mutations in the 4 AIDS patients are summarized.They showed different pathways on HIV-1 NNRTI drug resistance-associated mutations and those mutations detected early tend to be predominant strains.

OBJECTIVE:
The large sample retrospective cohort study were used to compare the diagnostic efficiency of PET/CT with conventional work-up (CWU) for evaluating nasopharyngeal carcinoma (NPC) distant metastasis.
METHOD:
Five hundred and fourteen patients with NPC were divided into PET/CT group and CWU group according the method of detecting distant metastasis. Chest film, abdominal ultrasonography, and bone scan were used in CWU group. Then the diagnostic efficiency of the two groups was compared.
RESULT:
Two hundred and sixteen patints were enrolled in PET/CT group and two hundred and nineteen-eight ones in CWU group. There were 28 out of 412 suspicious patients in CWU group were confirmed, another 3 patients confirmed without positive findings, compared with PET/CT group that all 32 suspicious patients were confirmed. The sensitivity and specificity of PET/CT were 100.0% (32/32) and 100.0% (184/184), as compared to 90.3% (28/31) and 94.8% (253/267) with CWU respectively, while there was no statistical significance. Further research found out that the percentage of patients with multiple distant metastatic sites and multiple organ metastases was higher in PET/CT group (P < 0.05), and similarly of patients with distant metastasis in N2-3 stages (P < 0.01).
CONCLUSION
Our results suggest that PET/CT appears to be slightly superior to conventional work-up in assessment of distant metastasis in NPC patients, but CWU is still a cheap and practical method.
