Objective To identify risk factors and preventive measures of nosoconial infections in patients with non-Hodgkin lymphoma (NHL). Methods Clinical data of 65 NHL patients admitted from January to December 2007 were retrospectively analyzed. Results According to WHO classification (2001), 58 patients were with B-cell lymphoma, 7 were with T-cell lymphorna. All patients received CHOP regimen as initial chemotherapy and 23 of them were with nosecomial infections. Logistic regression analysis demonstrated that age, length of stay, pathological type, bone marrow involvement, levels of serum lactate dehydrogenase (LDH), beta2-microglobulin and invasive treatment were identified as risk factors of nosocomial infections. Respiratory tract infections and infections with gram-negative microorganisms were the most popular. Conclusion High nosocomial infection rate is found in NHL patients, and control of risk factors may effectively prevent nosocomial infections in NHL patients.

Objective:
To understand rural students’ perception and satisfaction of the Nutrition Improvement Program for Rural Compulsory Education Students (NIPRCES), and to provide basis for promoting students’ participation in the school feeding program and improving the acceptability of school feeding.
Methods:
In 3 national pilot counties and 2 local pilot counties of NIPRCES, 1 middle school and 1 primary school were randomly selected. Two classes of 2 364 students from grade 4 to grade 9 were randomly selected and investigated with questionnaires.
Results:
Students were aware of the policy, with 78.9% of the students reported to be familiar with NIPRCES. The awareness rate of students at the national pilot areas was higher than that in local pilot areas(P<0.05). Students showed positive attitude towards NIPRCES. The median score of students’ understandings of the influence of NIPRCES was 20.0 (18.0, 20.0) points. Students in national pilot areas showed a more positive attitude toward the program than those in local pilot areas(P<0.05). Moderate satisfaction was reported in school feeding, 78.7% of students thought that school provided adequate amount of food, and 60.9% of the students enjoyed the food very much. The main reasons for leftovers were too much in amount(27.4%), repetition of food types (22.8%) and food aversions(9.2%).
Conclusion
Students are quite aware of NIPRCES and show moderate satisfaction in school feeding. The awareness and satisfaction are relatively higher among students in national pilot areas than those in local pilot areas. Health promoting schools should be established and students and parents should be advocated to take part in the program, health education need to be promoted in schools. Experiences sharing between different places could help improve the quality and acceptability of school feeding program.

OBJECTIVE:
To establish a screening model for females of reproductive age carrying Duchenne muscular dystrophy (DMD) variants based on a current community health examination platform.
METHODS:
A total of 61 870 participants were recruited between October 2017 and October 2019. Serum creatine kinase (CK) was measured with a Roche Cobasc 701/702 using an enzymatic rate method. Genetic testing was offered to those with a CK level of ≥ 200 U/L. For carriers of DMD variants, genetic counseling and follow up were provided.
RESULTS:
For the 61 870 females participating in the program, 1078 were found with raised serum CK (≥ 200 U/L), of which 618 (57.33%) accepted CK re-measurement after at least a two-week interval. One hundred and twenty cases were found with sustained serum CK elevation, of which 6 were confirmed to be definite DMD carriers regardless of family history. Genetic testing was provided to 33 females with a family history for DMD, and 13 were determined as definite carriers. An affected fetus was detected by prenatal diagnosis. After genetic counseling, the parents had opted induced abortion.
CONCLUSION
Large-scale DMD carrier screening through a three-step approach based on the current community health examination platform is both feasible and cost effective.

Objective:
To retrospectively explore the effects of modified dosage of calcium gluconate (CG) on the patients with hydrofluoric acid burns not in hands or feet.
Methods:
One hundred and sixty patients with hydrofluoric acid burns not in hands or feet were hospitalized in our burn ward from January 2004 to December 2017. Based on the dosage of CG at different admission time, 76 patients hospitalized from January 2004 to December 2012 were included in traditional group, and 84 patients hospitalized from January 2013 to December 2017 were included in modified group. For patients in the two groups, subcutaneous injection of CG solution at one time was immediately conducted on admission in topical treatment. In traditional group, the injection was CG solution with mass concentration of 100 g/L. For wounds of superficial partial-thickness and above degree, CG solution was prescribed at the dosage of 50 mg/cm2. Wounds of superficial-thickness or mass fraction of hydrofluoric acid less than 20.0% did not receive injection. In modified group, the mass concentration of CG solution for injection was diluted with normal saline to 25 g/L. For wounds of deep partial-thickness and above degree, CG solution was prescribed at the dosage of (50×mass fraction of hydrofluoric acid) mg/cm2. For wounds of superficial partial-thickness, CG solution was prescribed at the dosage of (25×mass fraction of hydrofluoric acid) mg/cm2. For wounds of superficial-thickness, CG solution was prescribed at the dosage of 2.5 mg/cm2. For systemic treatment, the injection velocity of CG solution via venous access was adjusted according to the level of serum calcium namely total serum calcium of patients in traditional group. In modified group, serum ionized calcium was additionally detected through automatic blood gas analyzer by the bed to regulate the injection velocity of CG via venous access. The incidence rate of hypercalcemia and mortality of patients after treatment in the two groups, and the situation about treatment of survivors in the two groups were analyzed. Data were processed with chi-square test, Fisher′s exact probability test,

Objective To study the therapeutic effect of anti-CD80 bivalent antibody on mouse lu-pus nephritis and to explore the possible molecular mechanism. Methods A mouse model of lupus nephritis was established through intraperitoneal injection of 0. 5 ml of pristine in female C57BL/6J mice. Appearance of urinary protein and significantly increased levels of peripheral antinuclear antibody ( ANA) and anti-doub-le-stranded DNA ( anti-dsDNA) antibody in the fourth month after injection indicated that the mouse model was established successfully. Then the mice were divided into two groups including anti-CD80 bivalent anti-body intervention group (injected with 200μg of anti-CD80 bivalent antibody at day 1, 3, 5, 8 and 15, fol-lowed by three times of injection with an interval of one month) and model group ( injected with the same protein using the same strategy). A normal control group was set up accordingly. Albustix test paper was used to monitor the dynamic changes in mouse urinary protein. Flow cytometry was used to analyze the acti-vation of immune-related cells in spleen. Levels of autoantibodies ( ANA and anti-dsDNA) and levels of IFN-γ and IL-4 in serum were detected by indirect immunofluorescence assay. Renal tissue samples were an-alyzed with hematoxylin and eosin ( HE) staining and immunocomplex ( IC) assay. Results Urinary pro-tein level of the anti-CD80 bivalent antibody intervention group was significantly lower than that of the model group (P<0. 05). Activated macrophages, dendritic cells, neutrophils and B cells in spleen tissues of the anti-CD80 bivalent antibody intervention group were significantly less than those of the model group ( P<0. 05), and the numbers of CD4+ and CD154+ T cells were significantly less than those of the model group (P<0. 05). Positive rates and titers of ANA and dsDNA in serum samples of the intervention group were lower than those of the model group (P<0. 05). Levels of IFN-γand IL-4 in serum samples of the interven-tion group were decreased as compared with those of the model group (P<0. 05). HE staining and immuno-fluorescence assay showed that glomerular inflammatory injury and necrosis were alleviated and kidney im-mune complex deposition was reduced after anti-CD80 bivalent antibody intervention. Conclusion Anti-CD80 bivalent antibody specifically binds to the CD80 molecule on antigen presenting cell surface, blocks the CD80/CD28 co-stimulatory signaling pathway and down-regulates the body′s immune response, which al-leviates and reverses the lupus-like nephritis-induced pathological damages in mice.

Brain metastasis is a common and serious complication of breast cancer, which is commonly associated with poor survival and prognosis. In particular, the treatment of brain metastasis from triple-negative breast cancer (BM-TNBC) has to face the distinct therapeutic challenges from tumor heterogeneity, circulating tumor cells (CTCs), blood-brain barrier (BBB) and blood-tumor barrier (BTB), which is in unmet clinical needs. Herein, combining with the advantages of synthetic and natural targeting moieties, we develop a "Y-shaped" peptide pVAP-decorated platelet-hybrid liposome drug delivery system to address the all-stage targeted drug delivery for the whole progression of BM-TNBC. Inherited from the activated platelet, the hybrid liposomes still retain the native affinity toward CTCs. Further, the peptide-mediated targeting to breast cancer cells and transport across BBB/BTB are demonstrated in vitro and in vivo. The resultant delivery platform significantly improves the drug accumulation both in orthotopic breast tumors and brain metastatic lesions, and eventually exhibits an outperformance in the inhibition of BM-TNBC compared with the free drug. Overall, this work provides a promising prospect for the comprehensive treatment of BM-TNBC, which could be generalized to other cell types or used in imaging platforms in the future.

Objective:
To evaluate the feasibility of combining simultaneous triple semicircular canal plugging (TSCP) and cochlear implantation (CI) to treat vertigo and hearing loss in advanced Meniere's disease(MD) patients, so as to provide an alternative surgical procedure for treating this disorder.
Methods:
Data from seven patients, who were referred to our hospital and diagnosed with unilateral MD strictly meeting the criteria issued by Chinese Academy of Otolaryngology-Head and Neck Surgery Committee (2006), from Jan. 2015 to Jan. 2016, were retrospectively analyzed in this work. Seven patients, in whom the standardized conservative treatment had been given for at least one year and frequent vertigo still occurred, underwent simultaneous TSCP and CI under general anesthesia via mastoid approach. Postoperative follow-up time was more than six months. Vertigo control and auditory function were measured. Pure tone audiometry, speech perception scores, caloric test, head impulse test (HIT), and vestibular evoked myogenic potential (VEMP) were performed for evaluation of audiological and vestibular functions.
Results:
All patients had bilateral severe sensorineural hearing loss preoperatively. One side hearing loss was due to MD and another side was due to reasons including sudden sensorineural hearing loss, mumps and other unknown reason. The total control rate of vertigo in seven MD patients was 100.0% in the six-month follow-up, with complete control rate of 85.7% (6/7) and substantial control rate of 14.3% (1/7). Improved hearing threshold and speech perception scores were observed in all study participants. Postoperative average aided hearing threshold was 32.5 dBHL, the average monosyllabic word score was 42.6% and speech perception scores of sentences tested in quiet was 52.3%. Tinnitus improved in five cases, and no significant change in two patients. Post-operatively, all patients suffered from temporary vertigo and balance disorders. Vertigo was disappeared in all patients within 3-5 days, while, an average recovery time of balance disorders was 19.7 days. Six months after treatment, loss of semicircular canal function by caloric test was found in the operation side of all patients and no change in cVEMP or oVEMP test was noted. All patients had no facial paralysis, cerebrospinal fluid leakage, and other complications.
Conclusions
A combined approach of TSCP and CI which could control vertigo effectively and improve hearing loss and tinnitus represents an effective and safe therapy for some advanced MD patients.
