Objective To study the effect and adverse drug reaction (ADR) of Diazepam when used to treat acute alcoholism for establishing its rational use. Methods According to the administration of the drug through different routes, 158 patients admitted from Jan. 2000 to Jan. 2006 were divided into two groups- intramuscular group (i.m., n=91) and intravenous group (i.v., n=67). There was no significant difference in age, sex, amount of liquor taken, time of seeing doctor, and drug dosage between the two groups. The effect and adverse drug reaction (ADR) of Diazepam were statistically analyzed. Results No ADR occurred in i.m. group and the effective rate was 92.31%. Although the effective rate in i.v. group was 100%, 3 patients suffered from cardiac arrest, 2 patients were found to have aspiration and apnea suddenly, and the ratio of ADR was 7.46%. Conclusion It is better to use intramuscular injection rather than intravenous injection in treating acute alcoholism with Diazepam, in order to avoid the serious medical incidents.

Surface modification of titanium implants is a hot topic for improving osteointegration and includes physical, chemical, bioactive and anodization methods. Among these methods, anodization methods can form TiO2 nanotube structures with a uniform and stable structure, and TiO2 nanotubes and substrates have high binding strengths and osteogenic properties and represent an excellent method for implant modification. TiO2 nanotube osteogenesis is closely related to its morphology, diameter and physicochemical characteristics. Therefore, the structure of TiO2 nanotubes with optimal osteogenic performance can be prepared by regulating these factors. At present, research on TiO2 nanotubes is mostly focused on composite treatments with TiO2 nanotubes, namely, the combination of other implant modification methods (physical method, chemical method, biological method) and TiO2 nanotubes to form a composite structure to work synergistically to treat osteogenesis. TiO2 nanotube composite treatment is a good prospective application for the further preparation of TiO2 nanotube-modified structures with strong osteogenic properties.

OBJECTIVETo investigate the treatment outcome, laryngeal preservation and side-effect in locally advanced hypopharyngeal carcinoma treated with combined Hilical tomotherapy (HT) or intensity-modulated radiotherapy (IMRT) and chemotherapy and/or EGFR inhibitor (Cetuximab or Nimotuzumab).

METHODSA total of 68 patients (20 cases with T1-2N1-3M0 and 48 cases with T3-4N1-3M0) with locally advanced hypopharyngeal cancer were treated individualy with non-surgical combined modality treatments including induction chemotherapy followed by concurrent chemoradiotherapy, induction chemotherapy followed by concurrent radiotherapy and EGFR inhibitor, concurrent chemoradiotherapy and EGFR inhibitor, and concurrent radiotherapy and EGFR inhibitor. HT was used in 40 patients and IMRT in 28 patients. Side-effects were evaluated with the established Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 criteria.

RESULTSThe average follow-up time was 25.7 months (range 3-69 months). All patients completed the planned radiotherapy without treatment breaks, and 66 (97.0%) of 68 patients completed the planned chemotherapy. The 2-year and 3-year overall survival rates were 78.8% and 64.7% respectively, with an organ preservation rate of 84.2%. The most common side-effect greater than or equal to grade 3 was oropharyngeal mucositis. No patient dependent on a percutaneous gastrostomy and tracheostomy tube.

CONCLUSIONHypopharyngeal carcinoma can be treated with non-surgical combined modality treatment including HT or IMRT, with a high laryngeal organ preservation rate and minimal toxicities.

Objective: To explore the correlation between different nutritional status and depressive symptoms among adolescents, so as to provide a theoretical basis for targeted improvement of nutritional status and depressive symptoms in adolescents. Methods: A total of 8 102 adolescents aged 12-17 years in Shanghai, Urumqi, Changsha and Kunming were selected by random cluster sampling. Depressive symptoms were assessed by the Center for Epidemiologic Studies Depression Scale(CES-D). Height and weight were measured. Kruskal Wallis H test, Chi square test and ordinal Logistic regression were used to analyze the relationship between nutritional status and depressive symptoms in adolescents. Results: The overall detection rate of depressive symptoms in adolescents was 25.6%, with girls (30.1%) higher than that of boys (21.1%) ( χ 2=87.60, P <0.01). There were statistically significant differences in the scores of depressive symptoms among girls with different nutritional status ( Z =8.34, P <0.05). The detectable rate of depressive symptoms increased with BMI among girls( χ 2 trend =6.04, P <0.05). After controlling for confounding factors, ordinal Logistic regression showed that the obese girls had higher risks in depressive symptoms detection compared with normal weight girls ( OR=1.45, 95%CI=1.10-1.91, P <0.05). Conclusion The nutritional status of girls is better than boys, but the prevalence of depressive symptoms is higher than boys. The risk of depressive symptoms in girls increases with BMI.

Objective: To explore the relationship between adolescents physical fitness and depressive symptoms, and to provide reference for the early prevention and intervention of depressive symptoms and improvement of physical fitness in Chinese adolescents. Methods: From September to December 2021, a total of 8 102 adolescents were selected by random cluster sampling method in Shanghai, Urumqi, Changsha and Kunming. The Center for Epidemiologic Studies Depression Scale(CES-D) was used to investigate the depressive symptoms, and completed grip strength, standing long jump, 50 m running, modified sitting forward flexion, 20 s repeated traverse, 30 s sit ups, 20 m round trip running (20 m SRT) test. χ 2 test, Goodman Kruskal Gamma and Logistic regression analysis were used to analyze the relationship between physical fitness index(PFI) and depressive symptoms. Results: The overall detection rate of depressive symptoms in adolescents with high level PFI was 23.4%, and the detection rate of low level adolescents was 26.3%, with a statistically significant difference ( χ 2=6.73, P =0.01). There was a significant positive correlation between PFI and depressive symptoms in the high school group ( G=0.09, P <0.05) and the boy group ( G=0.12, P < 0.05 ), and there was no significant association between PFI and depressive symptoms in the junior high school group and the girl group ( P >0.05). After adjusting for gender and age in the Logistic regression model, compared with those with high PFI, the risk of depressive symptoms in those with low PFI was 1.18 times (95% CI =1.05-1.33). Conclusion There is a correlation between physical fitness and depressive symptoms in adolescents. Adolescents with low PFI are at higher risk of developing depressive symptoms than those with high PFI.

ObjectiveTo investigate the effects of maltol aluminum exposure on miR-193a-3p, demethylase AlkB homolog 5 (ALKBH5), phosphatase and tensin homolog deleted on chromosome ten (PTEN) and protein kinase B (AKT), and whether miR-193a-3p is involved in aluminum-induced cognitive impairment by regulating ALKBH5/PTEN/AKT signaling pathway. Methods Specific pathogen-free male SD rats were randomly divided into control group and low-, medium- and high- dose groups according to their body weight, with eight rats in each group. Rats in the low-, medium-, and high- dose groups were intraperitoneally injected with maltol aluminum solution at concentrations of 10.00, 20.00, and 40.00 μmol/kg body weight, respectively, while the rats in control group were given an equal volume of 0.9% sodium chloride solution. Rats were injected for five days every week for three months. After injection, the novel object recognized test was used to assess the learning and memory ability of the rats. The relative expression of miR-193a-3p and B-cell lymphocytoma-2 (Bcl-2), Bcl-2 associated X protein (Bax) and cysteine aspartate protease-3 (Caspase-3) mRNA in rat hippocampus was detected using the real-time quantitative polymerase chain reaction. The relative protein expression of ALKBH5, PTEN, and AKT2 in the rat hippocampus was detected using Western blot. Results The discrimination index and the preference index of the new object recognition test of the rats in high-dose group were lower than those in control group and low-dose group (all P<0.05). The relative expression of miR-193a-3p and Bcl-2 mRNA in the hippocampus of the rats in high-dose group was lower than those in control group and low-dose group (all P<0.05). The relative mRNA expression of Bax in the high-dose group was higher than those in the control group and low-dose group (both P<0.05). The relative mRNA expression of Caspase-3 of the rats in the high-dose group was higher than that in the other three groups (both P<0.05). The relative protein expression of ALKBH5 in the hippocampus of the rats in the high-dose group was lower than that in the control group (P<0.05). The relative expression of PTEN protein was higher than those in the control group and low-dose group (both P<0.05). The relative protein expression of AKT2 was lower than those in the control group and low-dose group (both P<0.05). Conclusion Sub-chronic aluminum exposure can inhibit the expression of miR-193a-3p in the hippocampus of rats, which may disrupt the ALKBH5/PTEN/AKT pathway and affect normal neuronal homeostasis and cellular function. This pathway may play an important role in aluminum-induced cognitive impairment.
