Objective To observe effect of laryngeal function reconstruction of sternohyoid muscle inversion for treatment of glottic carcinoma. Methods A total of 106 patients with glottic carcinoma admitted to the Department of Otolaryngology in our hospital from January 2020 to December 2023 were selected and randomly divided into control group and observation group, with 53 patients in each group. The control group underwent vertical partial laryngectomy, while the observation group received vertical partial laryngectomy combined with thyrohyoid muscle inversion laryngeal reconstruction. Both groups were assessed for voice-related parameters[normalized noise energy (NNE), harmonic-to-noise ratio (HNR), jitter, shimmer], swallowing function[videofluoroscopic swallowing study (VFSS) score], quality of life[voice handicap index (VHI) score], improvement in phonation function, and incidence of complications (irritative cough, pharyngeal pain, dyspnea, laryngeal stenosis, local adhesion). Results Three months postoperatively, both groups showed significant decrease in NNE, jitter, and shimmer, and an increase in HNR compared to preoperative levels (P < 0.05). The observation group demonstrated lower NNE, jitter, and shimmer, and higher HNR than the control group at 3 months postoperatively (P < 0.05). Both groups had improved VFSS scores and reduced VHI scores at 3 months compared to preoperation (P < 0.05). The observation group showed higher VFSS scores and lower VHI scores than the control group at 3 months after operation (P < 0.05). The control group achieved an excellent or good rate of phonation function improvement was significantly lower than the observation group (88.68% versus 71.70%, P < 0.05). The incidence of complications in the observation group was significantly lower than that in the control group (9.43%versus 24.53%, P < 0.05). Conclusion The combination of vertical partial laryngectomy and laryngeal function reconstruction of sternohyoid muscle inversion for glottic carcinoma effectively improves voice-related parameters, swallowing function, quality of life, and phonation function, with a lower incidence of complications.

This study aims to evaluate the quality consistency of Saposhnikoviae Radix based on carbohydrates, and explore the potential of carbohydrates as the internal quality control indicators of Saposhnikoviae Radix. The total polysaccharides were quantified by UV-Vis spectrophotometry and the molecular weight range of the polysaccharides was determined by high performance gel-permeation chromatography-evaporative light scattering detection(HPGPC-ELSD). The monosaccharides in polysaccharides and the free monosaccharides were quantified by high performance liquid chromatography-UV detection(HPLC-UV), and the oligosaccharides and fructose were quantified by high performance liquid chromatography-evaporative light scattering detection(HPLC-ELSD). The carbohydrate-based quality of Saposhnikoviae Radix was compared among 45 batches of commercial samples and 13 batches of self-collected samples. The results showed that the molecular weight distribution, monosaccharide composition, oligosaccharide, and free monosaccharide composition were similar in the 58 batches of samples. The average content of total polysaccharides, oligosaccharides, and total free monosaccharides in commercial samples were 39.66, 148.79, and 68.62 mg·g~(-1), respectively. The content showed significant differences among batches, with the highest differences of 3.51, 1.75, and 2.58 times, respectively. The RSD of the relative ratios of monosaccharides in the polysaccharides in commercial samples reached 28%-45%. The average content of total polysaccharides, oligosaccharides, and total free monosaccharides in self-collected samples were 68.07, 145.76, and 42.04 mg·g~(-1), respectively, with the inter-region differences of 2.88, 1.88, and 1.07 times, respectively. The RSD of the relative ratios of monosaccharides in polysaccharides in self-collected samples ranged from 8.2% to 59%. The total polysaccharides and total free monosaccharides in self-collected samples were 1.72 times higher and 1.63 times lower, respectively, than those in commercial samples. The content of oligosaccharides was similar between self-collected samples and commercial samples. To sum up, carbohydrates are one of the material bases for the internal quality consistency of Saposhnikoviae Radix. The qualitative characteristics of polysaccharides and the quantitative characteristics of polysaccharides and oligosaccharides are related to the origin of medicinal materials. Moreover, the quantitative characteristics of polysaccharides and free monosaccharides may be related to the storage conditions. Carbohydrates are potential indicators for the quality control of Saposhnikoviae Radix and deserve attention.

Objective: To investigate the causative factors of renal function in newly diagnosed multiple myeloma (MM) patients with renal inadequacy. Methods: 181 MM patients with renal impairment from August 2007 to October 2021 at Peking Union Medical College Hospital were recruited, whose baseline chronic kidney disease (CKD) stage was 3-5. Statistical analysis was performed based on laboratory tests, treatment regimens, hematological responses, and survival among various renal function efficacy groups. A logistic regression model was employed in multivariate analysis. Results: A total of 181 patients were recruited, and 277 patients with CKD stages 1-2 were chosen as controls. The majority choose the BCD and VRD regimens. The progression-free survival (PFS) (14.0 months vs 24.8 months, P<0.001) and overall survival (OS) (49.2 months vs 79.7 months, P<0.001) of patients with renal impairment was considerably shorter. Hypercalcemia (P=0.013, OR=5.654) , 1q21 amplification (P=0.018, OR=2.876) , and hematological response over a partial response (P=0.001, OR=4.999) were independent predictive factors for renal function response. After treatment, those with improvement in renal function had a longer PFS than those without (15.6 months vs 10.2 months, P=0.074) , but there was no disparity in OS (56.5 months vs 47.3 months, P=0.665) . Conclusion: Hypercalcemia, 1q21 amplification, and hematologic response were independent predictors of the response of renal function in NDMM patients with renal impairment. MM patients with CKD 3-5 at baseline still have worse survival. Improvement in renal function after treatment is attributed to the improvement in PFS.

Objective: To describe the current status and trends in the treatment of patent ductus arteriosus (PDA) among very preterm infants (VPI) admitted to the neonatal intensive care units (NICU) of the Chinese Neonatal Network (CHNN) from 2019 to 2021, and to compare the differences in PDA treatment among these units. Methods: This was a cross-sectional study based on the CHNN VPI cohort, all of 22 525 VPI (gestational age<32 weeks) admitted to 79 tertiary NICU within 3 days of age from 2019 to 2021 were included. The overall PDA treatment rates were calculated, as well as the rates of infants with different gestational ages (≤26, 27-28, 29-31 weeks), and pharmacological and surgical treatments were described. PDA was defined as those diagnosed by echocardiography during hospitalization. The PDA treatment rate was defined as the number of VPI who had received medication treatment and (or) surgical ligation of PDA divided by the number of all VPI. Logistic regression was used to investigate the changes in PDA treatment rates over the 3 years and the differences between gestational age groups. A multivariate Logistic regression model was constructed to compute the standardized ratio (SR) of PDA treatment across different units, to compare the rates after adjusting for population characteristics. Results: A total of 22 525 VPI were included in the study, with a gestational age of 30.0 (28.6, 31.0) weeks and birth weight of 1 310 (1 100, 1 540) g; 56.0% (12 615) of them were male. PDA was diagnosed by echocardiography in 49.7% (11 186/22 525) of all VPI, and the overall PDA treatment rate was 16.8% (3 795/22 525). Of 3 762 VPI who received medication treatment, the main first-line medication used was ibuprofen (93.4% (3 515/3 762)) and the postnatal day of first medication treatment was 6 (4, 10) days of age; 59.3% (2 231/3 762) of the VPI had been weaned from invasive respiratory support during the first medication treatment, and 82.2% (3 092/3 762) of the infants received only one course of medication treatment. A total of 143 VPI underwent surgery, which was conducted on 32 (22, 46) days of age. Over the 3 years from 2019 to 2021, there was no significant change in the PDA treatment rate in these VPI (P=0.650). The PDA treatment rate decreased with increasing gestational age (P<0.001). The PDA treatment rates for VPI with gestational age ≤26, 27-28, and 29-31 weeks were 39.6% (688/1 737), 25.9% (1 319/5 098), and 11.4% (1 788/15 690), respectively. There were 61 units having a total number of VPI≥100 cases, and their rates of PDA treatment were 0 (0/116)-47.4% (376/793). After adjusting for population characteristics, the range of standardized ratios for PDA treatment in the 61 units was 0 (95%CI 0-0.3) to 3.4 (95%CI 3.1-3.8). Conclusions: From 2019 to 2021, compared to the peers in developed countries, VPI in CHNN NICU had a different PDA treatment rate; specifically, the VPI with small birth gestational age had a lower treatment rate, while the VPI with large birth gestational age had a higher rate. There are significant differences in PDA treatment rates among different units.

ObjectiveTo investigate the mechanism of Huangqi Guizhi Wuwutang （HQGZWWT） in the treatment of diabetic peripheral neuropathy （DPN） in MKR mice via regulating endoplasmic reticulum （ER） stress. MethodThirty-two 8-week-old MKR mice （half were male and half were female） were fed with a high-fat diet for four weeks， and then 1% streptozotocin （STZ） was injected intraperitoneally for five days. After the blood glucose was stabilized， the mice were housed in the cage covered with ice bags for another one hour stimulation per day for four weeks. Mice with fasting blood glucose （FBG） value ≥11.1 mmol·L^-1 were randomly divided into model group ， Huangqi Guizhi Wuwutang in original dosage group （30 g·kg^-1·d^-1）， Huangqi Guizhi Wuwutang in formula dosage group （6.25 g·kg^-1·d^-1）， and positive drug group （mecobalamin tablets， 0.17 mg·kg^-1·d^-1）. Another eight MKR mice of the same age were set as blank group and eight FVB mice were normal group. After four weeks of intragastric administration in each group， the change in FBG was tested， and hematoxylin and eosin （HE） staining and transmission electron microscope were used for observing the morphology of sciatic nerve tissue. In addition， the expression of c-Jun N-terminal kinase （JNK）， phosphorylated c-Jun N-terminal kinase （p-JNK） and inositol requiring enzyme 1α （IRE1α） proteins was determined by immunohistochemical test and Western blot （WB）. ResultCompared with the conditions in the normal group and blank group， the time of paw withdrawal， paw licking and tail flick in the model group was shortened （P<0.01）， and the conduction velocity of sciatic nerve was decreased （P<0.01）. Compared with the conditions in the model group， the behavioral and functional indicators were improved by HQGZWWT （P<0.05，P<0.01）. The immunohistochemical test revealed the JNK expression was elevated in the model group compared with the conditions in the normal group and blank group （P<0.05）， while that was lowered by HQGZWWT compared with the condition in the model group （P<0.05）. However， there was no difference among the treatment groups. According to the WB， the expression of IRE1α and p-JNK in the model group was enhanced compared with the conditions in the normal group and blank group （P<0.05，P<0.01）， while that was decreased by HQGZWWT compared with the condition in the model group （P<0.05，P<0.01）. No difference was observed between the HQGZWWTO and HQGZWWTF groups. ConclusionHQGZWWT can improve the neurophysiological function and pathological damage of sciatic nerve， which may be related to its delaying the ER stress response of sciatic nerve.

Background: Readmission after stroke is common, but limited data is available in West China. This study aimed to assess the frequencies and influencing factors of unplanned readmissions within 3 months after hospital discharge. Methods: This was a retrospective study in a single center. In our study, 596 ischemic stroke patients who were admitted to the Department of Neurology of West China Hospital from November 2011 to August 2012 were enrolled. Demographic data, disease data and follow–up data were collected at first admission and after 3 months of discharge. The readmission rate and risk factors were calculated. Results: Of 596 ischemic stroke patients, the readmission rate was 19.30% (115/596) within three-months, the top three reasons for readmission were needs of rehabilitation (74/115, 64.35%), recurrence of stroke (14/115, 12.17%), complications (11/115, 9.57%). The readmission was associated with older age, whether patients have indwelling catheter and endotracheal tube and pressure sores. (P < 0.05) Conclusions: The rate of readmission within 3 months in ischemic stroke patients was 19.30%. Greater attention should be paid to the elderly patients and patients with endotracheal tube on discharge to reduce readmission. Extended nursing care is also needed to reduce the readmission rate of patients with ischemic stroke.

Objective: To determine whether T1 mapping could monitor the dynamic changes of injury in myocardial infarction (MI) and be histologically validated. Materials and Methods: In 22 pigs, MI was induced by ligating the left anterior descending artery and they underwent serial cardiovascular magnetic resonance examinations with modified Look-Locker inversion T1 mapping and extracellular volume (ECV) computation in acute (within 24 hours, n = 22), subacute (7 days, n = 13), and chronic (3 months, n = 7) phases of MI. Masson’s trichrome staining was performed for histological ECV calculation. Myocardial native T1 and ECV were obtained by region of interest measurement in infarcted, peri-infarct, and remote myocardium. Results: Native T1 and ECV in peri-infarct myocardium differed from remote myocardium in acute (1181 ± 62 ms vs. 1113 ± 64 ms, p = 0.002; 24 ± 4% vs. 19 ± 4%, p = 0.031) and subacute phases (1264 ± 41 ms vs. 1171 ± 56 ms, p < 0.001; 27 ± 4% vs. 22 ± 2%, p = 0.009) but not in chronic phase (1157 ± 57 ms vs. 1120 ± 54 ms, p = 0.934; 23 ± 2% vs. 20 ± 1%, p = 0.109). From acute to chronic MI, infarcted native T1 peaked in subacute phase (1275 ± 63 ms vs. 1637 ± 123 ms vs. 1471 ± 98 ms, p < 0.001), while ECV progressively increased with time (35 ± 7% vs. 46 ± 6% vs. 52 ± 4%,p < 0.001). Native T1 correlated well with histological findings (R2 = 0.65 to 0.89, all p < 0.001) so did ECV (R2 = 0.73 to 0.94, all p < 0.001). Conclusion T1 mapping allows the quantitative assessment of injury in MI and the noninvasive monitoring of tissue injury evolution, which correlates well with histological findings.
