Objective:To compare the differences in specimen results between the intelligent robotic phlebotomy group and the manual venipuncture group, and to evaluate the clinical applicability of the autonomous blood collection system.Methods:From January 20 to October 28, 2022, 154 volunteers at Zhongshan Hospital, Fudan University underwent paired blood collections (robotic and manual) within 5 minutes. The collected samples were analyzed for: hemolysis index (HI), alanine transaminase (ALT), aspartate transaminase (AST), L-γ-glutamyltransferase (γ-GT), lactate dehydrogenase (LDH), urea nitrogen (UREA), creatinine (CRE), uric acid (UA), glucose (GLU), total cholesterol (TC), triglyceride (TG), natrium (Na), kalium (K), chlorine (Cl), creatine kinase (CK), CK-MB, CK-MM, and neuron-specific enolase (NSE). Statistical analyses used t-tests and Wilcoxon signed-rank tests.Results:The results of two different blood collection methods revealed that the HI values of 154 specimens in the intelligent robot blood collection group were all less than 20SI, while 7 specimens (4.54%) in the manual blood collection group had HI values exceeding 20SI; In the comparison of 17 biochemical and immunological markers, there were statistically significant differences between groups in 8 items including γ-GT[20.00(15.00, 37.75)U/L vs. 19.00 (14.00, 36.25)U/L, Z=2.497, P<0.05], LDH[165.5 (147.0, 183.0)U/L vs. 173.0 (155.0, 193.0)U/L, Z=8.629, P<0.05], TC[(5.002±0.856)mmol/L vs.(5.031±0.870) mmol/L, t=-3.006, P<0.05], K[4.1 (4.0, 4.3)mmol/L vs. 4.3 (4.1, 4.4)mmol/L, Z=5.592, P<0.05], CK[97.00 (73.00, 133.00)U/L vs. 99.00 (74.75, 136.25)U/L, Z=3.490, P<0.05], CK-MB[13 (11, 15)U/L vs. 14 (12, 16)U/L, Z=6.581, P<0.05], CK-MM[84.00 (60.00, 119.00)U/L vs. 83.50 (58.75, 118.00)U/L, Z=3.790, P<0.05], and NSE[10.600 (9.500, 11.700)ng/ml vs. 11.950 (10.475, 13.725)ng/ml, Z=8.151, P<0.05]. Conclusions:In the collection of serum samples, intelligent blood collection robots can achieve standardization and normalization of specimen collection volume and mixing in the pre-analysis stage. The hemolysis related indicators of the collected specimens are lower than those of the manual collection group, and can be used for the collection of clinical serological specimens.

This study was designed to evaluate the correlation between immune antibodies and pelvic inflammatory disease(PID)using retrospective analysis.Cases were selected from 171 patients who met the diagnosis of PID in Liuzhou People's Hospital of Guangxi Province from January 2022 to March 2023,and the PID patients were further divided into simple PID group(53 cases)and in PID combined with reproductive tract infection group(118 cases)according to the presence or absence of reproductive tract infections,while 83 cases of women who did not meet the specific diagnostic criteria of PID and did not have reproductive tract infections were selected as the control group during the same period.The positive rate of immune antibodies in the three groups were observed and compared to explore the relationship between immune antibodies and PID.Data showed that the positive rates of immune antibodies were significantly higher in the PID alone group and the PID combined with reproductive tract infection group than that in the control group.Furthermore,the positive rate of immune antibody TPOAb was significant difference in the PID combined with reproductive tract infection group and the PID alone group(P<0.05).In conclusion,TPOAb is closely associated with reproductive tract infections.

Objective To observe the clinical efficacy of Yinlian Gargle in the treatment of acute radiation-induced oropharyngeal mucositis after nasopharyngeal carcinoma radiotherapy.Methods Thirty-two patients with nasopharyngeal carcinoma,who had received first radiation,were randomly split into two groups:the trial group(19 cases)and the control group(13 cases).After all groups were treated with radiotherapy and chemotherapy,the control group was given rinse treatment with saline whereas the trial group was given Yinlian Gargle.The incidence of severe acute radiation-induced oropharyngeal mucositis,the duration and intensity of oropharyngeal discomfort and pain(NRS score),quality of life(QOL-NPC score),duration and intensity of radiation-induced side effects(SE-QOL-NPC score)and symptoms of dry mouth(SE1 score)were monitored before and after intervention in two groups.Results The incidence of grade Ⅲ or above radiation-induced oropharyngeal mucositis until the sixth week of radiotherapy in the trial group was considerably lower than that in the control group(P＜0.001),while the incidence of grade I or above radiation-induced oropharyngeal mucositis at 1 month after radiotherapy in the trial group was obviously lower than that in the control group(P＜0.001).The NRS score of pharyngeal discomfort of the trial group was lower than that of the control group starting from the second week of radiotherapy(P＜0.05).The NRS score of oral and oropharyngeal pain was lower than that of the control group starting from the fourth week of radiotherapy(P＜0.05).The SE1 score of the trial group was higher than that of the control group starting from the fifth week of radiotherapy(P＜0.05).After one month of the completion of the radiotherapy,the NRS score of pharyngeal discomfort and the NRS score of oral and oropharyngeal pain in the trial group were lower than those of the control group(P＜0.001).The QOL-NPC score,SE-QOL-NPC score,and SE1 score were all higher than those in the control group(P = 0.05 or P＜0.05).Conclusion Patients with nasopharyngeal cancer can greatly reduce their risk of developing severe acute radiation-induced oropharyngeal mucositis,effectively delay and relieve related symptoms,and enhance quality of life by consistently using Yinlian Gargle during radiotherapy.Additionally,a month after the completion of radiotherapy,it still has positive therapeutic effects on acute radiation-induced oropharyngeal mucositis.

The nutritional survey was made in 184 anorexia children aged 3-7, 123 of them were treated with various measures for three months. The results indicated that the children with anorexia had low intake and deficiency in energy, protein, minerals and vitamins. Most of them had zinc deficiency, but they simultaneously had two to three nutrients deficiency.The zinc treatment could improve most patient's syndrome and nutritional status. The effect of zinc treatment with vitamines and iron preparations was better than zinc treatment only. The effect of treatment with Chinese medicine also was able to cure the children with anorexia to certain extent.
