Bone marrow suppression is one of the common adverse reactions to radiotherapy and chemotherapy. Anticancer treatments such as radiotherapy and chemotherapy first directly damage the patient′s peripheral blood cells, impairing qi and blood; further, they damage the actively proliferating cell populations in the bone marrow, impairing yin and blood; and then they interfere with hematopoietic stem cells, impairing essence and blood. This process is rapid and intense, consistent with the characteristics of " acute deficiency syndrome" , marked by sudden onset, rapid changes, critical condition, complexity and variability, multiple complications, and poor prognosis. Given this, its diagnosis and treatment should differ from those of general deficiency syndromes. This paper advocates the principles and ideas of diagnosis and treatment such as " preventing first and treating early to prevent changes; supplementing for deficiency and strengthening vital qi to eliminate pathogenic factor; urgent rescue for critical conditions, no time to lose; and comprehensive supplementing throughout the process, with severe cases requiring singular action" . This approach is intended to provide theoretical reference and practical guidance for bone marrow suppression after radiotherapy and chemotherapy.

Objective: To determine the clinical efficacy of platelet-rich plasma (PRP) injection combined with warm acupuncture and moxibustion for treating patients with knee osteoarthritis and cold dampness obstruction syndrome. Methods: One hundred and twenty-eight patients with knee osteoarthritis and cold dampness obstruction syndrome who visited the Rehabilitation Department and Orthopedics Department of the Second Affiliated Hospital of Anhui University of Chinese Medicine from January 2023 to March 2024 and who met the inclusion and exclusion criteria were randomly divided into an experimental (n=64) and control group (n=64) using the random number table method. The experimental group was treated with PRP injection combined with warm acupuncture and moxibustion, whereas the control group was treated with normal saline injection combined with warm acupuncture and moxibustion treatment. PRP and normal saline injections were administered once every two weeks, a total of four times. Patients were treated with warm acupuncture and moxibustion once a day, six times a week, for four consecutive weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Traditional Chinese Medicine (TCM) syndrome, visual analog scale (VAS), and Lysholm scores were determined before treatment, at week 4 and week 8 of treatment, and week 16 of follow-up. Serum interleukin-6 (IL-6), matrix metalloproteinase-3 (MMP-3), tumor necrosis factor-α (TNF-α), osteoprotegerin (OPG), bone gla protein(BGP), and cartilage oligomeric matrix protein (COMP) levels were compared between the two groups before and after 8 weeks of treatment. The clinical efficacy and safety indicators between the two groups were also compared. Results: There was no statistical difference in baseline data such as gender, age, disease duration, and body mass index between the two groups of patients. Compared with before treatment, both groups showed decreased WOMAC total and subscale, TCM syndrome total score and symptom scores, and VAS scores, and an increase in Lysholm scores at 4, 8, and 16 weeks after treatment. After treatment, serum IL-6, MMP-3, TNF-α, and COMP levels decreased, whereas serum OPG and BGP levels increased (P<0.05). Compared with the control group, patients in the experimental group showed decreased WOMAC total and subscale, TCM syndrome total score and symptom scores, and VAS scores, and an increase in Lysholm score at 4, 8, and 16 weeks after treatment. Compared with the control group, patients in the experimental group showed decreased serum IL-6, MMP-3, TNF-α, and COMP levels and an increase in serum OPG and BPG levels after treatment (P<0.05). The total effective rate of the experimental group was 91.94%, higher than that of the control group (81.97%; P<0.05). Conclusion PRP injection combined with warm acupuncture and moxibustion can improve various TCM symptoms, improve knee joint function and bone metabolism, and reduce inflammation in patients with knee osteoarthritis and cold dampness obstruction syndrome.

AIM: To analyze the clinical features and multimodal imaging features of peripapillary hyper-reflective ovoid mass-like structure(PHOMS).METHODS: Retrospective observation study. Totally 35 patients(56 eyes)with PHOMS that diagnosed in the Affiliated Eye Hospital of Nanjing Medical University from January 2020 to March 2024 were included in the study. All patients underwent fundus photography, fundus fluorescein angiography, fundus autofluorescence, optical coherence tomography, and B-ultrasound.RESULTS:PHOMS occurred across diverse age groups, with an insidious onset often detected incidentally during routine ophthalmic examinations. More patients came to hospital for refractive errors due to blurred vision The boundary of the optic disc is blurred on fundus photography, and the nasal eminence is more significant, showing a “C” shaped halo. No obvious abnormal fluorescence was observed on fundus autofluorescence and fundus fluorescein angiography during different periods. An elevated appearance in vary degrees with more prominent in the nasal parts was showed on different OCT scans. Vertical scanning on the nasal side of the optic disc showed the best PHOMS structure, which could be seen under the retinal nerve fiber layer and on the Bruch membrane, with sharply marginated hyper-reflective ovoid mass-like structures, and no shielding effect on the choroid. The higher the elevation, the larger the volume. Ocular B-mode ultrasound showed a pre-optic disc bulge on the posterior wall of the eyeball, and there was no strong signal echo in it.CONCLUSION:PHOMS can be found frequently in myopic patients and often asymptomatic. Transient vision loss and floaters may occur in symptomatic cases. The most typical OCT feature is a nasally located hyper-reflective ovoid structure with distinct margins.

Objective: To investigate the association between dietary behaviors and overweight and obesity among middle school students, so as to provide the evidence for developing dietary intervention strategies for them. Methods: From October to December 2023, a total of 7 063 middle school students from six counties (districts) in Ma'anshan City, Anhui Province were selected through stratified cluster random sampling method. Demographic information, physical activity, sleep, and dietary behaviors over the past year were collected through questionnaire surveys. Height and weight were measured to calculate body mass index (BMI), with overweight and obesity determined based on gender- and age-specific BMI cut-off points. The association between dietary behaviors and overweight and obesity was analyzed using a multivariable logistic regression model. Results: Totally 7 063 questionnaires were allocated, and 7 045 valid questionnaires were recovered, with an effective recovery rate of 99.75%. There were 3 925 males (55.71%) and 3 120 females (44.29%). A total of 2 326 students were overweight and obesity, with the prevalence of 33.02%. There were significant differences in the prevalence of overweight and obesity among middle school students with different genders, whether they were the only child or not, different intake frequency of sugar-sweetened beverages, and different intake frequency of beans and soy products (all P<0.05). After adjusting for factors such as gender, education stage, whether the only child, whether living on school, physical activity and sleep, multivariable logistic regression analysis showed that the frequency of snack consumption (1-2 times/week, OR=0.803, 95%CI: 0.669-0.963; 3-6 times/week, OR=0.759, 95%CI: 0.623-0.926; daily, OR=0.758, 95%CI: 0.595-0.964), sugar-sweetened beverages consumption (1-2 times/week, OR=1.166, 95%CI: 1.012-1.343; daily, OR=1.891, 95%CI: 1.302-2.746) and beans and soy products consumption (1-2 times/week, OR=0.787, 95%CI: 0.628-0.987) were the influencing factors of overweight and obesity among middle school students. Conclusions The frequencies of snack, beans and soy products and sugar-sweetened beverage consumption are associated with overweight and obesity among middle school students. Targeted interventions should be strengthened to reduce the risk of overweight and obesity.

AIM: To analyze the correlation between ocular surface status and serum lipids in patients with meibomian gland dysfunction(MGD)during pregnancy, and to provide new ideas for the management and treatment of MGD during pregnancy.METHODS: Totally 120 pregnant women(240 eyes)treated in our hospital from May 2021 to May 2022 were selected and they were divided into MGD group(60 cases, 120 eyes)and control group(60 cases, 120 eyes)according to the presence or absence of MGD. All subjects received the ocular surface disease index scores(OSDI)and underwent examinations of meibomian gland morphology and function, tear film and blood lipid.RESULTS: The scores of OSDI, the related indexes of meibomian gland, corneal fluorescein staining(FL)scores, total cholesterol(TC), triglyceride(TG)and low density lipoprotein-cholesterol(LDL-C)in the MGD group were significantly higher than those in the control group(P<0.05). The scores of fluorescein breakup time(FBUT), Schirmer Ⅰ test(SIt)and high-density lipoprotein cholesterol(HDL-C)in the MGD group were significantly lower than those in the control group(P<0.05). Correlation analysis showed that the scores of TG, TC, LDL-C were negatively correlated with the values of FBUT(rs =-0.702, -0.647, -0.710, all P<0.001).CONCLUSION: The level of blood lipids in pregnant patients with MGD is significantly increased, and the levels of TC, TG and LDL-C may be related to the stability of tear film.

Objective To investigate the clinical effect and hearing loss of endolymphatic sac decompression(ESD)combined with one or two semicircular canal obstruction(SCO)in treating the patient with stage Ⅲ or stageⅣ Meniere disease.Methods Forty-three patients with stage Ⅲ or stage Ⅳ Meniere disease,who failed to respond to conventional conservative treatment and had the expectation of preserving residual hearing function,were enrolled in the study.They were divided into three groups according to the operation they underwent:ESD combined with lateral and posterior semicircular canal obstruction(ESD+LPSCO)13 cases,ESD combined with lateral semicircu-lar canal obstruction(ESD+LPSCO)14 cases,and ESD only 16 cases.Data of vertigo,ear fullness and tinnitus be-fore and after operation was collected,analyzed and compared.Hearing function before and after the operation was also evaluated.Results The number of vertigo attacks in the three groups(ESD+LPSCO,ESD+LSCO,and ESD)were all significantly reduced after operation.The vertigo control rate were 92.3％,78.6％and 62.5％re-spectively.Compared with pre-operation,the vertigo severity post-operation in the three groups were also signifi-cantly reduced.And the improvement rate of vertigo severity after ESD+LPSCO and ESD+LSCO were both 100％,which were significantly higher than that of ESD(68.8％).The discomfort of tinnitus and ear fullness in the three groups were significantly improved compared with that of pre-operation.The improvement rates of tinnitus in the three groups were 46.2％,50.0％and 43.8％respectively,with no significant difference.The improvement rate of ear fullness in the three groups were 61.5％,57.1％and 50.0％respectively,with no significant difference either.The proportion of patients with decreased hearing after operation in the three groups was 15.4％,7.1％and 18.8％,respectively,and the differences were insignificant.Conclusion ESD combined with one or two SCO can effectively control vertigo and other symptoms of patients with stage Ⅲ or Ⅳ Meniere's disease who had failure to conventional conservative treatment,and can preserve the residual hearing function in considerable extent.

Objective:To explore therapeutic effect of cardiac rehabilitation based on traditional exercise on heart failure(HF).Methods:We searched databases including CNKI,Wanfang,VIP,Pubmed and Cochrane library for literature about application of cardiac rehabilitation exercise based on traditional exercises in HF patients before Mar 2023.Literature were screened according to inclusion and exclusion criteria,while article quality assessment and da-ta extraction were performed,and RevMan 5.3 software was used to perform Meta analysis.Results:Meta analysis indicated that compared with control group,there were significant increase in LVEF[MD=4.51,95％CI(1.70,7.33),P=0.002]and 6 min walking distance[6MWD,MD=51.90,95％CI(39.24,64.57),P=0.001],and sig-nificant reductions in left ventricular end-systolic diameter[MD=-1.64,95％CI(-3.18,-0.11),P=0.040],left ventricular end-diastolic diameter[MD=-2.49,95％C1(-3.28,-1.69),P=0.001],score of Minnesota living with heart failure questionnaire[MD=-6.89,95％CI(-8.64,-5.33),P=0.001]and level of N-ter-minal pro-brain natriuretic peptide[MD=-151.46,95％CI(-208.21,-94.70),P=0.001]in observation group.Conclusion:Cardiac rehabilitation based on traditional exercise can significantly improve heart function,in-crease 6 min walking distance and improve quality of life in patients with heart failure.

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3％,and that of non-infected group was 23.1％,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2％(95％CI:-2.3％-22.8％).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P＞0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P＞0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.

Severe cerebrovascular disease is a kind of severe cerebrovascular disease involving disturbance of consciousness,which corresponds to the viscera of stroke in traditional Chinese medicine(TCM).Rooted in the TCM classics such as Huang Di Nei Jing(The Yellow Emperor's Inner Classic)and Shang Han Lun(Treatise on Cold Damage),Professor WU Hai-Ke studied the TCM pathogenesis theory recorded in the chapter of Profound and Important Theory in Plain Questions(Su Wen)carefully.Based on its clinical practice and inherited the traditional four diagnostic methods of inspection,auscultation-olfaction,interrogation,and palpation,Professor WU Hai-Ke simplified and created the six-differentiation method for the syndrome differentiation of patients with severe cerebrovascular disease:distinguishing the mind to learn the progression of the disease,distinguishing the complexion to know the exuberance or decline of qi and blood,distinguishing the tongue picture to predict the aggravation or relief of the disease,distinguishing the pulse condition to judge the prognosis,distinguishing the breath to know the deficiency or excess of zang-fu organs,and distinguishing cold-heat to identify the exterior,interior,yin and yang.The six-differentiation method highlights the significance of mind,complexion,tongue picture,pulse condition,breath,and cold-heat in the syndrome differentiation of patients with severe cerebrovascular disease.The clinical information of six-differentiation method is easy to obtain,and the method presents the characteristics and advantages of TCM diagnostic methods in the syndrome differentiation of patients with severe cerebrovascular disease,which will provide reference for the establishment of clinical diagnosis and treatment norms of TCM for severe cerebrovascular disease.
