Objective To observe the clinical efficacy of Lingnan fire needling in the treatment of plaque psoriasis.Methods A total of 60 cases of patients with plaque psoriasis admitted to Bao'an Hospital of Chinese Medicine Affiliated to Guangzhou University of Chinese Medicine from August 2021 to January 2023 were selected,and the patients were randomly divided into the observation group and the control group according to the random number table method,with 30 cases in each group.The observation group was given Lingnan fire needling for treatment,and the control group was given topical application of Calcipotriol Ointment.The course of treatment covered eight weeks continuously.After eight weeks of treatment,the clinical efficacy of the two groups was evaluated,and the changes of Psoriasis Area and Severity Index(PASI)scores and Dermatology Life Quality Index(DLQI)scores,as well as the diameter of glomus under dermoscopy of the patients in the two groups were observed before the treatment and after 2,4,6,and 8 weeks of treatment.Changes in Generalized Anxiety Disorder Scale(GAD-7)scores before treatment and after 2,4,6,and 8 weeks of treatment were compared between the two groups.Results(1)After 2,4,6 and 8 weeks of treatment,the scores of PASI,DLQI and GAD-7 of patients in the two groups were improved significantly(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(2)The cured and markedly rate of the observation group was 86.67%(26/30);and that of the control group was 66.67%(20/30).The efficacy of the observation group was superior to that of the control group,the difference being statistically significant(P<0.05).(3)After 2,4,6,and 8 weeks of treatment,the diameter of glomus under dermoscopy of the patients in the two groups were improved significantly(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).Conclusion Lingnan fire needling therapy for plaque psoriasis can effectively improve the clinical symptoms of the patients,relieve the anxiety symptoms induced by skin lesions and itching,so as to improve their quality of life.

This article introduces Professor Zhou Peng's clinical experience in treating generalized anxiety disorder(GAD)using spirit-regulating and root-strengthening integrated acupuncture.Based on the pathological characteristics of GAD,Professor Zhou Peng summarizes its pathogenesis as"disharmony of qi,blood,yin,and yang,"pointing out that"deficiency"is the essence of its onset,with spleen and kidney deficiency being the root cause.He advocates treating GAD from the perspective of"deficiency and decline,"focusing on strengthening the spleen and kidneys,consolidating the root,and nourishing the source,while also regulating the mind.The integrated acupuncture therapy includes needling,refined moxibustion,and intradermal needle embedding.Needling is used to harmonize qi and blood,refined moxibustion to regulate and supplement yin and yang to consolidate the root,and intradermal needle embedding to regulate the mind and consolidate the therapeutic effects of acupuncture.Starting from improving patients'compliance with treatment and ensuring sustained therapeutic effects,Professor Zhou emphasizes that acupuncture manipulation should be fast,gentle,and soft,with needle insertion resembling a swift crane touching the waves and needle manipulation like a deer drinking from a clear spring.He places great importance on patients'sensations and aims to holistically regulate the body's qi,blood,yin,and yang,restoring the balance of body and mind,thereby effectively treating generalized anxiety disorder.

Objective:To evaluate the effect of teacher simulate standardized patient (TSSP) consultation training in pediatric practical teaching.Methods:A total of 120 interns from the five-year clinical medicine major of Batch 2015 were randomly divided into experimental group and control group. In the experimental group, 60 interns were trained by TSSP for consultation after admission. After the training, the clinical parents of the children were consulted and the children were physically examined under the guidance of teachers. In the control group, 60 interns were trained according to the same requirements, but TSSP consultation training was not included. At the end of the practice, the performance, operation skills and medical record writing ability of the interns were compared, and the satisfaction of the experimental group was investigated. SPSS 25.0 software was used for t test and chi-square test. Results:The medical record writing results of the experimental group were (96.15±3.00) points, significantly higher than that of the control group [(81.02±3.29) points], and the differences were statistically significant ( t = 26.38; P < 0.001). In the mini-clinical evaluation exercise (Mini-CEX), the scores of medical history collection, communication skills, humanistic care and physical examination were significantly higher than those of the control group ( t= 15.41, 17.67, 15.39 respectively; all P < 0.001). The experimental group had high satisfaction with the teaching method of TSSP consultation training. Conclusion:TSSP consultation training improves the intern medical record writing ability, doctor-patient communication ability, clinical operation ability, stimulates the learning interest of interns, trains the trainee doctors humanistic consciousness, integrates into the ideological and political education, effectively ensures the quality of practical teaching of pediatrics, and obtains recognition from intern, which is worth promoting.

Objective:In order to explore the impact of corona virus disease 2019(COVID-19)on the hospitalization of children with bronchiolitis and to improve clinicians′ understanding of the characteristics of bronchiolitis during the COVID-19 epidemic.Methods:This was a multicenter clinical study, and the data have been collected from 23 children′s medical centers in China.All the clinical data were retrospectively collected from children with bronchiolitis who were hospitalized at each study center from January 1, 2019 to December 31, 2021.The results included gender, age at hospitalization, length of stay, respiratory syncytial virus(RSV) test results, severity rating, ICU treatment, and the total number of children hospitalized with respiratory tract infection during the same period.The clinical data of children with bronchiolitis in 2019 before COVID-19 epidemic and in 2020、2021 during COVID-19 epidemic were statistically analyzed and compared.Results:According to a summary of data provided by 23 children′s medical centers, there were 4 909 cases of bronchiolitis in 2019, 2 654 cases in 2020, and 3 500 cases in 2021.Compared with 2019, the number of bronchiolitis cases decreased by 45.94% in 2020 and 28.70% in 2021.In 2019, 2020 and 2021, there were no significant differences in gender ratio, age, and duration of hospitalization.Compared with 2019, the ratio of bronchiolitis to the total number of hospitalizations for respiratory tract infection decreased significantly in 2020 and 2021( χ2=12.762, P<0.05; χ2=84.845, P<0.05).The proportion of moderate to severe bronchiolitis cases in both 2020 and 2021 was lower than that in 2019, and the difference was statistically significant ( χ2=4.054, P<0.05; χ2=8.109, P<0.05).There was no statistically significant difference in the proportion of bronchiolitis cases requiring ICU treatment between 2019, 2020, and 2021 ( χ2=1.914, P>0.05).In 2019, a total of 52.60%(2 582/4 909) of children with bronchiolitis underwent RSV pathogen testing, and among them, there were 708 cases with RSV positive, accounting for 28.00%.In 2020, 54.14%(1 437/2 654) of children with bronchiolitis underwent RSV pathogen testing, and there were 403 cases with RSV positive, accounting for 28.04%.In 2021, 66.80%(2 238/3 500) of children with bronchiolitis underwent RSV pathogen testing, and there were 935 cases with RSV positive, accounting for 41.78%.Compared with 2019 and 2020, the RSV positive rate in 2021 showed a significant increase( χ2=99.673, P<0.05; χ2=71.292, P<0.05). Conclusion:During the COVID-19 epidemic, the implementation of epidemic prevention and control measures reduced the hospitalization rate and severity of bronchiolitis, but did not reduce the positive rate of RSV detection.

Objective:To explore the in vitro antiviral activity of Mizoribine (Miz) against BK polyomavirus (BKV) and analyze preliminarily the replication stage during inhibition.Methods:The solvent of Miz, was employed as a negative control, while Sirolimus (Sir) with in vitro anti-BKV activity was applied as a positive control. Firstly, the half maximal inhibitory concentrations (IC50) of Miz and Sir were analyzed in different cell lines. Then, prior to BKV infection, cells were treated with a gradient of drug concentrations according to the IC50 results. At different timepoints post-infection, BKV replication curves were measured by quantitative detection of its DNA in supernatant while the cells were subjected to immunofluorescence for detecting the infection rate. Finally 293FT cells treated with drugs was infected by BKV single-round pseudovirus for determining the effects of Miz on the early stage of BKV infection.Results:As compared with control group, immunofluorescence showed a lowered infection rate of BKV in a Miz dose-dependent manner, viral replication curve was significantly inhibited according to the quantitative detection of viral DNA in cell supernatant. The inhibitory effect of Sir on the level of BKV infection and replication was similar to that of Miz. However, neither Miz nor Sir exhibited a significant effect on the early stage of BKV infection.Conclusions:Miz has anti-BKV activity at cellular level and the inhibitory effect does not appear in the early stage of viral infection.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

Objective To evaluate the effect of conversion from mycophenolic acid (MPA) to mizoribine (MZR) in renal transplant recipients with gastrointestinal tract (GI) symptoms.Methods A total of 355 renal transplant recipients with GI symptoms caused by MPA administration were enrolled from April 2015 to March 2017 in 25 different renal transplant centers in China.The symptomatic improvement of GI before (baseline) and after conversion to MZR (1,2,4 weeks) was assessed by each item of GI symptoms indication.In addition,the efficacy and safety of the conversion therapy during 12 months were determined.Results Patients showed improvement in GI symptoms including diarrhea,abdominal pain,abdominal distention and stomachache after conversion to MZR 1,2,4 weeks (P＜0.05).In patients with different severity of diarrhea,conversion to MZR therapy significantly improved diarrhea (P＜0.05).During 12 months,no patient experienced clinical immune rejection.We did not observe any infections,leucopenia and other serious side effects.Conclusion MZR could markedly improve GI symptoms caused by MPA administration in renal transplant recipients.

BACKGROUND:Fractures of shafts of the tibia and fibula are the most common diaphyseal fractures among al long bones. The clinical significance of fibula fixation in treatment of distal third shaft fractures is controversial, and the studies are also different. OBJECTIVE:To explore the clinical significance of fibular fixation in treatment of distal third tibia shaft fractures. METHODS:A retrospective review has been performed on the clinical data of sixty-four cases with distal third tibia shaft fracture in Department of Orthopedics, China National Offshore Oil Corporation General Hospital from January 2006 to March 2010. Al cases were divided into two groups based on whether the fibula was fixed or not: fibula fixation group (n=36) and fibula non-fixation group (n=28). Union rate of fracture, bone union time and tibial valgus angle were compared between the two groups. According to Merchant-Dietz criteria, the ankle range of motion and ankle evaluation score were evaluated and compared between the two groups. RESULTS AND CONCLUSION: No significant difference in union rate of fracture, bone union time and ankle range of motion was detected between two groups. Tibial valgus angle was smaler in the fibula fixation group (5.42±1.16)° than in the fibula non-fixation group (7.54±1.90)°(P=0.006). Ankle function score was higher in the fibula fixation group (93.58±0.97) than in the fibula non-fixation group (90.57±3.92) (P=0.000). Three cases in the fibula fixation group suffered from superficial wound infection, and achieved good healing after treatment of anti-infection and changing dresses. Above results verify that fibular fixation can reduce tibial valgus angle and improve ankle joint function in treatment of distal third tibia fractures.

BACKGROUND:Currently, hematopoietic stem celltransplantation mainly depends on unrelated donors. Mental state of the unrelated donors is very important to ensure the successful celltransplantation. OBJECTIVE:To compare mental and physical health status of relative and unrelated donors during the hematopoietic stem cellcol ection. METHODS:We compared the mental (Symptom Checklist-90) and physical (temperature, breath, pulse, and blood pressure) health status of relative and unrelated donors at admission, 1 day before cellcol ection, and 1-2 days after cellcol ection.RESULTS AND CONCLUSION:At admission, there was no difference in the mental health status of relative and unrelated donors (P>0.05), while the scores on Symptom Checklist-90 were significantly higher in the unrelated donors than the relative donors, including total score, forced, depression, anxiety, hostility, and fear (P<0.05). The physical signs were steady in the unrelated and relative donors, but the difference in breath and systolic blood pressure was of great significance before and after cellcol ection in the two groups. These findings indicate that during cellcol ection, the unrelated donors exhibit heavier mental load than the relative donors, and psychological counseling and health guidance are necessary.

BACKGROUND:Extreme lateral lumbar disc herniation is a rare type of lumbar disc herniation, there are a variety of treatment methods, but the therapeutic efficacy and recurrence rate are controversial.
OBJECTIVE:To investigate the availability of lumbar pedicle screw fixation combined with interbody fusion cage for treating extreme lateral lumbar disc herniation.
METHODWe retrospectively analyzed 19 patients with extreme lateral lumbar disc herniation after treatment with lumbar pedicle screw fixation combining with interbody fusion cage from March 2006 to January 2009. The outcomes were evaluated depending on VAS scoring standard and Macnab scoring standard, lumbar stability were observed postoperatively. We analyzed the spinal stability in recurrent lumbar disc herniation patients after lumbar pedicle screw fixation combined with interbody fusion cage depending on literature search.
RESULTS AND CONCLUSION:Al the 19 patients were fol owed up for 13 months to 3 years, the leg and lumbar pain of al the patients were relieved to varying degrees. Preoperative VAS score was 7.3±1.28 points and postoperative VAS score was 2.1±0.8 points, showing significant difference between two groups (P<0.05). The excellent and good rate was up to 95%with 15 excellent results, 3 good results and 1 acceptable result depending on Macnab evaluation standard. There was no pedicle screw loosening, broken, non-fusion phenomenon. Al the lumbar interbody fusions were good. No one occurred secondary lumbar spinal stenosis. Experimental findings indicate that, lumbar pedicle screw fixation combined with interbody fusion cage for extremely lateral lumbar disc herniation, is characterized as fast symptom relief, strong fixation and good lumbar stability.
