Objective To explore the relationship between the status of infarct related artery(IRA)occlusion and thrombus types in patients with non-ST-segment elevation myocardial infarction(NSTEMI)using optical coherence tomography(OCT).Methods A total of 170 NSTEMI patients who underwent emergency percutaneous coronary intervention at Henan Provincial People1s Hospital from October 2021 to August 2023 and underwent OCT examination were included in the study.Among them,83 cases were in the total occlusion group and 87 cases were in the non-total occlusion group.The baseline characteristics,coronary angiography findings,and OCT results of the patients were compared and analyzed.Results Compared with the non-total occlusion group,the patients in the total occlusion group were more younger(P=0.013),the proportion of male was higher(P=0.026),and the proportion of patients with hypertension(P=0.010)and diabetes(P=0.033)was lower.In the total occlusion group,left circumflex artery(LCX)served as the main IRA,whereas in the non-total occlusion group,left anterior descending(LAD)was the predominant IRA(P=0.012);In addition,there was a significantly higher occurrence of rentrop grade Ⅱ～Ⅲ in the total occlusion group compared to the non-total occlusion group(P=0.022).The OCT results showed that in most cases,the total occlusion group was caused by plaque rupture events(P=0.014),mainly red/mixed thrombus(P＜0.001);The non-total occlusion group was more commonly associated with plaque erosion events(P=0.014),with white thrombus being the main cause(P＜0.001).Conclusions Total occlusion of infarct-related artery in NSTEMI patients often occurs in the LCX,and the patient is more younger,the thrombus type is mainly red/mixed thrombus,while non-total occlusion lesions are mainly white thrombus.

Objective: To investigate the feasibility of only surgical resection for nasal vestibular squamous cell carcinoma and the efficacy of perforator flap of ipsilateral nasolabial sulcus in repairing postoperative defects. Methods: The clinical data of 8 cases with squamous cell carcinoma of the nasal vestibule who admitted to Department of Facial Plastic and Reconstructive Surgery, Eye & ENT Hospital, Fudan University were analyzed, including 6 males and 2 females, aged from 38 to 75 years. The tumor of the nasal vestibule was eradicated in time after making definite diagnosis of lesions, then the perforators flap of the ipsilateral nasolabial sulcus was used for repairment, without performing further chemotherapy or radiotherapy after surgery. The tumor recurrence, facial appearance, nostril form, donor area scar, nasal ventilation function, and cutaneous sensation were evaluated after surgery. Descriptive analysis was used in this research. Results: There were 2 cases of stage T1 and 6 cases of stage T2 in 8 cases. After 32 to 45 months of following-up, no recurrence accurred and all the flaps survived well. However, there was about 2 mm necrosis of the transplanted flap in the lateral foot of the alar in one case, which was healed well by carrying out wound care after 10 d. And the dark color flap was occurred in another case, showing the flap's backflow trouble, yet it was improved with addressing timely during 5 d postoperation. Pincusion-like deformity of the transplanted flap occurred in 4 cases (50%), which subsided gradually after 6 months. The morphology of the anterior nostril was altered in 4 cases (50%), but there was no ventilation trouble and no need for addressment in any case. The postoperative facial appearance was rated as excellentor good with hidden scar in the donor site, and the sensation of the transplanted flaps was indistinct from the surrounding tissue after 3 months. Conclusions: Surgical resection of nasal vestibular squamous cell carcinoma with tumor stage T1-2 is a feasible treatment. And it is the one of the best reconstructive methods of the perforator flap of the ipsilateral nasolabial sulcus to repair the deformities after the surgery.

This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.

OBJECTIVE: To compare minimally invasive and traditional Chevron osteotomy in treating patients with mild to moderate hallux valgus. METHODS: Clinical data of 36 patients (36 feet) with mild to moderate hallux valgus from January 2019 to February 2021 were retrospectively analyzed, and divided into minimally invasive osteotomy(minimally invasive group) and traditional Chevron osteotomy(traditional group). There were 16 patients in minimally invasive group, including 1 male and 15 females, aged from 36 to 60 years old with an average of(49.0±9.5) years old;9 were mild and 7 were moderate according to Mann classification;treated with minimally invasive osteotomy with hollow screw fixation. There were 20 patients(20 feet) in traditional group, including 2 males and 18 females, aged from 38 to 65 years old with an average of(50.0±9.2) years old;11 were mild and 9 were moderate according to Mann classification;treated with traditional Chevron osteotomy. Hallux valgus angle (HVA), intermetatarsal angle (IMA) before and after operation at 12 months bewteen two groups were observed and compared, and American Orthopedic Foot and Ankle Society (AOFAS) forefoot score and visual analogue scale (VAS) before and after operation at 6 weeks and 12 months between two groups were compared. RESULTS: Thirty-six patiens were followed up from 14 to 30 months with an average of (21.00±5.77) months. All incisions were healed well at stageⅠwithout infection. There were no significant differences in HVA, IMA, AOFAS forefoot scores and VAS before and after operation at 12 months between two groups(P>0.05). However, AOFAS forefoot scores and VAS of minimally invasive group was significantly better than that of traditionl group at 6 weeks after operation (P<0.05). Postoperative HVA, IMA, AOFAS forefoot scores and VAS at 12 months bewteen two groups were improved better than that of preoperation(P<0.05). CONCLUSION Compared with traditional Chevron osteotomy, minimally invasive osteotomy has less trauma and quicker recovery. Both of them has similar clinical effects, and could receive satisfactory clinical effects, while treatment of minimally invasive osteotomy should pain attention to learning curve.

Objective To investigate the effect of facet joint asymmetry on lumbar biomechanics in normal and patients with adolescent lumbar disc hemiation (ALDH). Methods Mimics 21.0, 3-Matic Medical 13.0, Geomagic Wrap 2017, HyperMesh 2019 and finite element software ABAQUS 2021 were combined to establish three-dimensional finite element models of nonnal lower lumbar spine and adolescent lumbar disc hemiation. According to the difference between the left and right facet joints, three cases of nonnal and ALDH patients aged 13-18 years old were selected, with a total of 6 cases. The stress of intervertebral disc under different torque loads (neutral position, lateral flexion and rotation) was analyzed and compared. Results 1. Three dimensional finite element models of L3-L, segments were established in 6 male nonnal and adolescent patients with lumbar disc herniation, and the stress and displacement nephogram of lumbar disc hemiation in nonnal neutral position, flexion, extension, lateral flexion and rotation were obtained; 2. The stress of L4_, annulus fibrosus increased when the facet joint angle of nonnal adolescents was symmetrical in the neutral position; 3. The stress of annulus fibrosus was greater than that of nucleus pulposus under different conditions, and the stress of annulus fibrosus was flexion > neutral position > extension; 4. In patients with ALDH, the left side of the facet joint was larger than the right 10 ° model, and the stress in the posterior side of the annulus fibrosus of L4_, segment increased significantly under extension condition. Under lateral flexion condition, the left stress of the left annulus fibrosus was compared with the right stress of the right annulus fibrosus, t = l. 575, P<0. 05, the difference was statistically significant, the right stress of the right annulus fibrosus was greater than the left stress of the left annulus fibrosus. Under the rotating condition, the stress on the left and right sides of the fiber ring was greater than that on the back side. Conclusion 1. Compared with nonnal and patients with ALDH, the stress of intervertebral disc increases under different postures, which ma)' increase the shear load of intervertebral disc and aggravate the process of intervertebral disc degeneration; 2. When the degree of left-right asymmetry of facet joint is more than 10 degrees, the stress on the side with small degree is greater. Facet joint asymmetry can lead to the overload of vertebral bod)' and intervertebral disc, leading to spinal instability; 3. The stress of intervertebral disc in extension is less than that in neutral position and flexion. Extension can relieve the pressure of intervertebral disc and play an auxiliary role in the recovery of patients with ALDH.

BACKGROUND: Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China. METHODS: The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD. RESULTS: A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082-4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606-3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044-1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061-2.424), DRI (OR, 2.094; 95% CI, 1.328-3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679-4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777-6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996-0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379-0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160-0.467) were preventive factors for BPD (all P < 0.05). CONCLUSION Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.

Objective:To construct the targeting evaluation method of traditional Chinese medicine （TCM） preparations based on supramolecular Qi chromatography theory， and to study the liver targeting effect of Bupleuri Radix on Pien Tze Huang. Method:The molecular connectivity index （MCI） was used to analyze the characteristics of imprinted template and liver targeting tendency of TCM mainly attributed to liver meridian and components of Pien Tze Huang， and combined with target dynamics and total statistical moment principle， aimed at the independent action characteristics of multi-component imprinted template of TCM， a method for evaluating the targeting of TCM preparations was established. Hepatoma rats in Pien Tze Huang group， Bupleuri Radix group， Pien Tze Huang+Bupleuri Radix group and blank group were tested and verified. Result:After the average value of MCI of TCM mainly attributed to liver meridian was deducted， the MCI similarity between Pien Tze Huang group and Bupleuri Radix group was 0.376 8， Pien Tze Huang+Bupleuri Radix group and Bupleuri Radix group was 0.988 2， so it was predicted that Bupleuri Radix could enhance the liver targeting of Pien Tze Huang. A system for evaluating the targeting of TCM compounds was established， including relative total uptake efficiency （RUE_T）， relative total concentration （RC_T）， relative imprinted tendency （RIT_T） and relative imprinted variance （RIV_T）. The RUE_T and RC_T of liver were the highest in all tissues （RUE_T=1.88>1，RC_T=2.30>1）， and the corresponding values of other tissues were all <1， indicating that Pien Tze Huang combined with Bupleuri Radix could increase its distribution in liver and enhance liver targeting. Except for plasma， the RIT_T and RIV_T of other tissues fluctuated around 1.0， indicating that targeted modification did not change imprinted tendency of Pien Tze Huang and had no significant effect on the types of components. Conclusion:Under the guidance of supramolecular Qi chromatography theory， a targeting evaluation parameter system can be established to characterize the multi-component imprinted effect of TCM preparations by MCI and total statistical moment parameters， so as to realize the evaluation of targeting of TCM preparations. The addition of Bupleuri Radix can increase the liver targeting of Pien Tze Huang.
