OBJECTIVES: The diagnostic value of ultrasonographic quantitative indicators of umbilical cord coiling, such as the umbilical coiling index (UCI) and pitch value, in identifying hypercoiling and predicting adverse pregnancy outcomes remains controversial. This study aims to evaluate the predictive value of UCI, pitch value, and the cerebroplacental ratio in pregnancies complicated by umbilical cord hypercoiling. METHODS: Pregnant women with densely coiled umbilical cords identified by routine obstetric ultrasound at Changsha Maternal and Child Health Hospital between November 2022 and November 2024 were enrolled. Complete clinical data, including UCI, pitch value, and cerebroplacental ratio (CPR), were collected. Pregnancy outcome scores were calculated, and newborns were categorized into the normal outcome group (n=177) and adverse outcome group (n=85), with the latter further subdivided into mild (n=51), moderate (n=19), and severe (n=15) subgroups. Differences in baseline data, UCI, pitch value, and incidence of CRP<1 were compared between groups and among subgroups. Correlations between UCI, pitch value, and adverse pregnancy outcomes were analyzed. Receiver operating characteristic (ROC) curve were used to assess the predictive performance of UCI, pitch value, CPR<1, and their combinations. RESULTS: Compared with the normal outcome group, the adverse outcome group had higher age, parity, parity, incidence of CPR<1, and UCI, while gestational age at delivery and pitch values were lower (all P<0.05). The incidence of obesity, gestational diabetes mellitus, and hypertensive disorders of pregnancy did not differ significantly between the 2 groups (all P>0.05). The normal outcome group showed lower UCI and higher pitch values than all 3 adverse outcome subgroups (all P<0.05), while differences among the 3 adverse subgroups were not significant (all P>0.05). UCI was positively correlated with adverse pregnancy outcomes (r_s=0.350, P<0.05), whereas pitch value was negatively correlated (r_s=-0.286, P<0.05). ROC curve analysis showed that the area under the curve (AUC) values for predicting adverse outcomes were 0.837 for UCI, 0.886 for pitch value, and 0.610 for CPR<1, with sensitivities of 77.6%, 82.4%, and 27.1% and specificities of 78.5%, 83.6%, and 94.9%, respectively. The combined UCI+CPR<1 and pitch value+CPR<1 models yielded AUCs of 0.841 and 0.886, with sensitivities of 78.8% and 81.2% and specificities of 78.5% and 84.2%, respectively. No significant differences were found between the AUCs of UCI and pitch value (P>0.05), but both outperformed CPR<1 alone (both P<0.001). The combined models showed no significant improvement over UCI or pitch value alone (both P>0.05), though both were superior to CPR<1 alone (both P<0.001). CONCLUSIONS Most umbilical cord hypercoiling cases had favorable outcomes, with UCI, pitch value, CPR<1 and their combinations demonstrating significant predictive value for adverse pregnancy outcomes.

There are millions of patients with taxane-induced peripheral neuropathy （TIPN）， and there is no effective treatment or prevention measure in clinical practice. The occurrence of TIPN may be related to the dosage form of paclitaxel drugs， genetic and molecular markers， drug dosage and chemotherapy cycle， patient factors， etc. At present， drugs for treating TIPN mainly include those that inhibit axonal degeneration （such as dosazosin， tamsulosin）， prevent mitochondrial dysfunction （such as glutathione trisulfides， antioxidants α -lipoic acid）， improve calcium imbalance in the internal environment （Shaoyao gancao decoction， N-type voltage-gated calcium channel inhibitor IPPQ）， and inhibit neuroinflammation （such as chemokine inhibitors and selective interleukin-8 receptor inhibitors DF2726A）. Further exploration of drug treatment strategies targeting different induction mechanisms is expected to become a new direction for precise clinical prevention and personalized treatment of TIPN.

Objective:To analyze the effects of basic treatment of periodontal diseases combined with orthodontic treatment on periodontal pocket depth and bleeding index (BI) in patients with anterior tooth displacement caused by periodontal diseases.Methods:A total of 136 patients with anterior tooth displacement due to periodontal disease treated in the Second People′s Hospital of Yueqing from October 2020 to October 2022 were enrolled and they were divided into two groups by random number table method, and each group with 68 cases. The control group was given basic treatment for periodontal disease, while the experimental group was combined with orthodontic treatment on the basis of the control group. The clinical efficacy, masticatory efficiency, periodontal pocket depth (PD), probing BI, gingival sulcus inflammatory factors and the total incidence of complications were compared between the two groups.Results:The total effective rate in the experimental group was higher than that in the control group: 95.59%(65/68) vs. 79.41%(54/68), there was statistical difference ( P<0.05). After treatment for 3 months, the masticatory efficiency in the experimental group was higher than that in the control group, and PD, BI in the experimental group were lower than that in the control group: (70.52 ± 6.88) % vs.(61.52 ± 4.04) %, (2.12 ± 0.62) mm vs. (3.18 ± 0.85) mm, (1.26 ± 0.26) scores vs. (2.42 ± 0.33) scores, there were statistical differences ( P<0.05). After treatment, the levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and IL-8 in the experimental group were lower than those in the control group: (11.16 ± 1.85) μg/L vs. (16.92 ± 2.84) μg/L, (8.16 ± 1.34) ng/L vs. (15.49 ± 2.74) ng/L, (6.18 ± 1.46) ng/L vs. (10.33 ± 1.75) ng/L, there were statistical differences ( P<0.05). The total complication rate in the experimental group was lower than that in the control group: 1.47%(1/68) vs. 11.76%(8/68), there was statistical difference ( P<0.05). Conclusions:Basic treatment of periodontal diseases combined with orthodontics can effectively improve the masticatory efficiency of patients with anterior tooth displacement caused by periodontal diseases, reduce PD,BI and alleviate gingival sulcus inflammation, and reduce the incidence complications.

Objective To investigate the effects of low dose of extracellular histone on endothelial cells in infectious diseases such as sepsis. Methods The endothelial cells were treated with 10 μg/mL recombinant human histone H3/H4 complex in replacement of calf thymus histones (CTH) for various periods of time, and the morphology changes and the viability of the endothelial cells were recorded. In addition, flow cytometry was applied to identify the characteristics of endothelial cells and enzyme-linked immunosorbnent assay (ELISA) was used to detect the extracellular histones level in endothelial cells culture. Results The low dose of CTH could continuously induce endothelial cells death, cell morphological changes and function loss, which was reproduced by 10 μg/mL recombinant histone H3/H4 complex. Results of histones quantitation showed that histone can cause a series of intracellular reactions in a short period of time. Conclusions It is showed that 10 μg/mL H3/H4 can induce the toxicity in infectious disease and this level of the dose is a lower than those used in previous studies and more close to the pathological conditions.

Objective To investigate the anxiety status of male partner involved in induced abortion and to analyze influencing factors related.Methods Male partners of the patients undergoing induced abortion in the gynecology and obstetrics department of a hospital in Kunming in April and May in 2015 were selected and a questionnaire survey was conducted.Self-rating Anxiety Scale (SAS) was used to measure the anxiety status and SPSS 17.0 was used for statistical analysis.Results A total of 53 out of 205 male partners were found to have anxiety symptoms (25.9％),with 44 cases of mild anxiety (21.5％),8 cases of moderate anxiety (3.9％) and 1 case of severe anxiety (0.5％).The main related risk factor was times of pregnancy (OR=3.35) while the protective factors were level of education (OR =0.60),times of induced abortion (OR =0.20) and age (OR =0.32) Conclusion When abortion occurs,the male partner's anxiety appears,mainly with mild and moderate one,and female's emotion are also affected.It is important to strengthen health education and popularize contraceptive knowledge so as to reduce the incidence of anxiety.

Objective To realize rapid and non-destructive drug classification and improve the accuracy of drug classification.Methods A model for drug classification based on the combination of principal components analysis and artificial neural network (PCA-ANN) method was introduced.The software for drugs classification was then developed with the utility of MATLAB language.The near infra-red spectrum (NIRS) detection technique was executed on five kinds of drugs (a total of 120 batch samples) and the detection data was collected within the range of 1 350-1 800 nm of excitation wavelength and 0.5 nm of wavelength interval.Results The network training mean square error (MSE) was 5.91e-03,and the prediction error (β) was 2.469％ when the number of the interfering drugs number was less than 5.Conclusions The classification of drugs by NIRS combined with PCA-ANN is feasible and the classification accuracy can be increased.

Objective To analyze the clinical features of the hospitalized children with laboratory-confirmed influenza in Suzhou. Methods The demographic information, laboratory test results, clinical features, treatments and outcomes of the hospitalized children with laboratoryconfirmed influenza were collected retrospectively. The data were analyzed using chi square test,Cochran-Armitage trend test. Results Four hundred and eighty hospitalized children were diagnosed with laboratory-confirmed influenza during the period of 2005 to 2009. Among these cases, 414 were subtype A and 66 were subtype B. The positive rate was 2.66%. Four hundred and nineteen cases (87.29 %) were ≤ 5 years old. Most of the cases developed during winter (from December to April the next year) and summer (from July to August). The age and sex distribution didn't vary from year to year (x2=9. 7768,x2 = 8. 7573; both P＞0.05). The mean disease course was (16.22± 9.41)days, and the mean hospitalization duration was (7.89 ±2.97) days. The percentages of patients with symptoms of fever, dyspnea and diarrhea or requiring oxygen treatment decreased with age (Z =4. 9430, Z=2. 1021, Z=3. 2073 and Z=2. 3277, respectively; all P＜0.05). The percentages of cases with concomitant pneumonia and upper respiratory infection also decreased with age (Z =-3. 8762 and Z=-3. 5095, respectively; both P＜0.01). Fifteen point five percent (60/387 cases)of the cases were co-infected with pneumococcus and 15. 0% (72/480 cases) were co-infected with respiratory syncytial virus (RSV). The level of C-reactive protein was significantly higher in cases with bacterial co-infection than those with viral co-infection (Z= -3.1290, P ＜ 0. 01 ).Conclusions Hospitalized children with influenza are more common in winter and summer in Shuzhou.Many patients are co-infected with pneumococcus or RSV. The symptoms are more severe in younger children.
