Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

Objective:To explore the application value of Oxford nanopore technologies (ONT) in the diagnosis and treatment of periprosthetic joint infection (PJI).Methods:A prospective analysis was conducted on 32 patients with PJI admitted to the joint department of Xi'an Honghui Hospital from October 2021 to March 2023, who met the 2018 PJI diagnostic criteria of the American Skeletal Infection Society (MSIS), including 15 males and 17 females with an average age of 63.93±8.93 years. 32 revision patients who did not meet the 2018 MSIS PJI criteria during the same period were collected as controls (non PJI group), including 13 males and 19 females with an average age of 65.53±8.54 years. All patients underwent joint fluid puncture before or during surgery, and the specimens were tested by ONT, metagenomic next generation sequencing (mNGS), and general microbial culture. The receiver operating characteristic (ROC) curves were drawn for both groups, and the sensitivity, specificity, positive predictive value, negative predictive value, and Youden index of the three detection techniques were calculated and compared to evaluate the detection efficiency of different detection methods in PJI.Results:Among the 32 patients with PJI, 30 were positive for ONT, with a total of 30 pathogenic bacteria detected, and the detection time was 22.37±8.36 h. 31 were positive for mNGS, with a total of 33 bacterial species detected, and the detection time was 46.25±9.36 h. 17 were positive for microbial culture, with a total of 8 bacterial species detected, and the detection time was 96.23±15.62 h. Among the 32 patients with non PJI group, 1 was positive for ONT and 5 were positive for mNGS, with a total of 1 and 3 bacterial species detected, respectively. The results of microbial culture were all negative. The detection time and area under the curve (AUC) of ONT and mNGS were 22.37±8.36 h and 0.953[95% CI (0.901, 1.006)], 46.25±9.36 h and 0.906[95% CI (0.835, 0.977)], respectively, which were better than those of microbial culture 96.23±15.62 h and 0.766[95% CI (0.678, 0.853)], and the difference was statistically significant ( P<0.05). The sensitivity of ONT, mNGS, and microbial culture were 0.938, 0.969, and 0.531, respectively, and the specificity was 0.969, 0.844, and 1.000, respectively. The Jordan index was 0.906, 0.813, and 0.531, respectively. Conclusion:ONT testing has higher diagnostic efficacy than mNGS and microbial culture in the diagnosis of PJI, and also has advantages in detection time. It also suggests that some PJI are not caused by a single microbial infection.

Objective To investigate the clinical effect of lengthened proximal femoral nail anti-rotation(PFNA)in the treatment of Seinsheimer type Ⅴ subtrochanteric fracture of femur.Methods The clinical data of 21 patients with Seinsheimer type Ⅴ subtrochanteric fracture of femur treated by closed reduction or limited incision wire binding combined with lengthened PFNA in our hospital from January 2020 to August 2022 were retrospectively analyzed.The fracture healing status,treatment effect,postoperative complications and Harris score of hip joint function at the last postoperative follow-up of patients were recorded and evaluated.Results All patients were followed up for 6 to 12 months,and the fractures healed well.There were no cases of internal fixation breakage or cutting,no cases of vascular injury,and 1 case of ectopic ossification.At the last follow-up,the hip joint function was excellent in 15 cases,good in 4 cases and fair in 2 cases,with an excellent and good rate of 90.48％.Conclusion Lengthened PFNA can effectively treat Seinsheimer type Ⅴ subtrochanteric fracture of femur,and minimally invasive steel wire cerclage is performed when the closed reduction is not ideal,which has the advantages of less trauma,fast fracture healing,fewer postoperative complications and good recovery of hip joint function,and is worthy of clinical promotion and application.

Objective:To observe the clinical efficacy and action mechanism of Jujing Decoction(JJD)in the treatment of as-thenoteratozoospermia(ATZ)by comparing JJD with combined administration of the antioxidant stress drug and sperm energy metabo-lism agent.Methods:According to the inclusion criteria,we enrolled 67 male patients with ATZ in this randomized controlled clini-cal study and treated them by oral administration of JJD(the JJD group,n=34)or natural vitamin E combined with L-carnitine solu-tion(the positive control group,n=33),both for 12 weeks.We collected the semen parameters,sperm DNA fragmentation index(DFI),sperm mitochondrial membrane potential(MMP),seminal plasma reactive oxygen species(ROS)and superoxide dismutase(SOD)levels from the patients,observed the ultrastructure of sperm mitochondria under the transmission electron microscope(TEM)before and after treatment,and analyzed the clinical efficacy and action mechanism of JJD by comparing the data obtained between the two groups.Results:Treatment and follow-up were completed in 60 of the cases,30 in the JJD and 30 in the positive control group.The total rate of clinical effectiveness was significantly higher in the JJD than in the positive control group(76.8％vs 43.3％,P＜0.05).Compared with the baseline,the percentages of progressively motile sperm(PMS)and morphologically normal sperm(MNS),DFI and MMP were significantly improved(P＜0.05),the level of seminal plasma ROS decreased(P＞0.05),and that of SOD re-markably increased(P＜0.05)after treatment with JJD;PMS,MNS,DFI and MMP were also improved(P＞0.05),seminal plas-ma ROS decreased(P＞0.05)and SOD increased(P＜0.05)in the positive controls after medication.In comparison with the posi-tive controls,the patients treated with JJD showed even more significant improvement in PMS([29.37±14.56]％vs[42.68±15.86]％,P＜0.05),MNS([1.84±1.32]％vs[3.66±1.72％]％,P＜0.05),DFI([32.66±5.23]％vs[16.61±4.20]％,P＜0.05)and MMP([46.47±9.48]％vs[61.79±8.61]％,P＜0.05),ROS([7.08±0.51]vs[5.06±0.52]μmol/L,P＞0.05),and SOD([100.65±10.59]vs[139.05±14.71]U/ml,P＜0.05).TEM revealed significantly improved ultrastructure of sperm mitochondria after treatment with JJD.No serious adverse reactions were observed in either group dur-ing follow-up.Conclusion:JJD,superior to natural vitamin E and L-carnitine oral solution,can safely and effectively increase the percentages of PMS and MNS,MMP and the level of seminal plasma SOD,reduce sperm DFI and seminal plasma ROS,and improve the ultrastructure of sperm mitochondria in patients with ATZ.The underlying mechanism of action may be related to its ability of im-proving the structure and function of sperm mitochondria via antioxidant stress.

Background In mainland China, patients with neovascular age-related macular degeneration (nAMD) have approximately an 40% prevalence of polypoidal choroidal vasculopathy (PCV). This disease leads to recurrent retinal pigment epithelium detachment (PED), extensive subretinal or vitreous hemorrhages, and severe vision loss. China has introduced various treatment modalities in the past years and gained comprehensive experience in treating PCV.Methods A total of 14 retinal specialists nationwide with expertise in PCV were empaneled to prioritize six questions and address their corresponding outcomes, regarding opinions on inactive PCV, choices of anti-vascular endothelial growth factor (anti-VEGF) monotherapy, photodynamic therapy (PDT) monotherapy or combined therapy, patients with persistent subretinal fluid (SRF) or intraretinal fluid (IRF) after loading dose anti-VEGF, and patients with massive subretinal hemorrhage. An evidence synthesis team conducted systematic reviews, which informed the recommendations that address these questions. This guideline used the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach to assess the certainty of evidence and grade the strengths of recommendations. Results The panel proposed the following six conditional recommendations regarding treatment choices. (1) For patients with inactive PCV, we suggest observation over treatment. (2) For treatment-na?ve PCV patients, we suggest either anti-VEGF monotherapy or combined anti-VEGF and PDT rather than PDT monotherapy. (3) For patients with PCV who plan to initiate combined anti-VEGF and PDT treatment, we suggest later/rescue PDT over initiate PDT. (4) For PCV patients who plan to initiate anti-VEGF monotherapy, we suggest the treat and extend (T&E) regimen rather than the pro re nata (PRN) regimen following three monthly loading doses. (5) For patients with persistent SRF or IRF on optical coherence tomography (OCT) after three monthly anti-VEGF treatments, we suggest proceeding with anti-VEGF treatment rather than observation. (6) For PCV patients with massive subretinal hemorrhage (equal to or more than four optic disc areas) involving the central macula, we suggest surgery (vitrectomy in combination with tissue-plasminogen activator (tPA) intraocular injection and gas tamponade) rather than anti-VEGF monotherapy. Conclusions Six evidence-based recommendations support optimal care for PCV patients' management.

Objective: To examine the safety and effectiveness of inflatable video-assisted mediastinoscopic transhiatal esophagectomy (IVMTE). Methods: Totally 269 patients admitted to the Anhui Provincial Hospital of Anhui Medical University who underwent IVMTE (IVMTE group, n=47) or thoracoscopy combined with minimally invasive Mckeown esophageal cancer resection (MIME group, n=222) from September 2017 to December 2021 were analyzed retrospectively. There were 31 males and 16 females in IVMTE group, aged (68.6±7.5) years (range: 54 to 87 years). There were 159 males and 63 females in MIME group, aged (66.8±8.8) years (range: 42 to 93 years). A 1∶1 match was performed on both groups by propensity score matching, with 38 cases in each group. The intraoperative conditions and postoperative complication rates of the two groups were compared by t test, Wilcoxon rank, χ² test, or Fisher exact probability method. Results: Patients in IVMTE group had less intraoperative bleeding ((96.0±39.2) ml vs. (123.8±49.3) ml, t=-2.627, P=0.011), shorter operation time ((239.1±47.3) minutes vs. (264.2±57.2) minutes, t=-2.086, P=0.040), and less drainage 3 days after surgery (85(89) ml vs. 675(573) ml, Z=-7.575, P<0.01) compared with that of MIME group. There were no statistically significant differences between the two groups in terms of drainage tube-belt time, postoperative hospital stay, and lymph node dissection stations and numbers (all P>0.05). The incidence of Clavien-Dindo grade 1 to 2 pulmonary infection (7.9%(3/38) vs. 31.6%(12/38), χ²=6.728, P=0.009), total complications (21.1%(8/38) vs. 47.4%(18/38), χ²=5.846, P=0.016) and total lung complications (13.2%(5/38) vs. 42.1%(16/38), χ²=7.962, P=0.005) in the IVMTE group were significantly lower. Conclusion: Inflatable video-assisted mediastinoscopic transhiatal esophagectomy combined with laparoscopic esophagectomy is safe and feasible, which can reach the same range of oncology as thoracoscopic surgery.

OBJECTIVE: To provide guidance for hip replacement by analyzing the variation of femoral head rotation center in different hip diseases. METHODS: A total of 5 459 patients were collected from March 2016 to June 2021, who took positive and proportional plain films of both hips for various reasons. The relative position between the rotation center of the femoral head and the apex of the greater trochanter was measured. The positive variation is more than 2 mm above the top of the great trochanter, and the negative variation is more than 2 mm below the top of the great trochanter. A total of 831 patients with variation of femoral head rotation center were collected and were divided into 4 groups according to different diseases, and the variation was counted respectively. There were 15 cases in the normal group involving 10 cases of positive variation and 5 cases of negative variation. There were 145 cases of avascular necrosis of femoral head involving 25 cases of positive variation and 120 cases of negative variation. There were 346 cases of congenital hip dysplasia involving 225 cases of positive variation(including 25 cases of typeⅠ, 70 cases of type Ⅱ, 115 cases of type Ⅲ and 15 cases of type Ⅳ), and 121 cases of negative variation(including 50 cases of crowe typeⅠ, 60 cases of typeⅡ, 10 cases of type Ⅲ and 1 case of type Ⅳ). There were 325 cases of hip osteoarthritis group involving 45 cases of positive variation and 280 cases of negative variation. RESULTS: There was significant difference in variation of femoral head rotation center among the four groups(P<0.05). There was significant difference in variation of femoral head rotation center among different types of congenital hip dysplasia(P<0.05). There were significant differences in cervical trunk angle and eccentricity among different variations of femoral head rotation center(P<0.05). CONCLUSION The variation of femoral head rotation center is related to cervical trunk angle and eccentricity. The variation of femoral head rotation center is an important factor in hip diseases. The variation of femoral head rotation center is different in different hip diseases. Avascular necrosis of the femoral head and osteoarthritis of the hip were mostly negative variations. With the aggravation of congenital hip dysplasia, the variation of femoral head rotation center gradually changed from negative variation to positive variation.The variation of femoral head rotation center should be paid attention to in the preoperative planning of hip arthroplasty. It is of great significance to select the appropriate prosthesis and place the prosthesis accurately.

Aim To investigate the mechanism of high salt-induced cerebral artery remodeling in mice by up-regulating TMEM16A. Methods Forty C57BL/6J mice were randomly divided into four groups (10 per group, 8 weeks of intervention), namely, blank control group (normal diet), low-salt group (2% high salt diet), medium-salt group (4% high salt diet) and high-salt group (8% high salt diet). HE staining was used to observe the morphological changes of cerebral arteries; blood vessel permeability test was used to compare the color and absorbance value of brain tissue. Immunofluorescence was employed to detect TMEM16A expression in cerebral arteries of mice in each group; PCR and Western blot were applied to detect the mRNA and protein expression of TMEM16A in cerebral arterial tissues; whole-cell patch clamp was use to record the calcium-activated chloride channel (CaCC) currents of mouse cerebral artery smooth muscle cells in each group. Results HE results showed that 2%, 4%, and 8% high salt diet could concentra-tion-dependently induce cerebral arterial wall thickening and lumen stenosis in C57BL/6J mice. The permeability test found that compared with the control group, the absorbance value of the brain tissue of the mice in the 2%, 4% and 8% high salt groups increased significantly. The results of isolated muscle tension showed that compared with the control group, the systolic response of isolated cerebral arteries to 60 mmol • L

Objective: To explore the diagnostic values of HK2 testing and single-cell sequencing in the urothelial carcinoma (UC). Methods: The qualified urine specimens of 265 suspected UC patients or postoperative patients from the Cancer Hospital of Chinese Academy of Medical Sciences, Beijing, China were collected. Both exfoliative cytology and HK2 testing were performed on clinically suspected UC or postoperative patients. The performance of diagnostic cytology and HK2, including consistency, sensitivity, specificity, positive predictive value and negative predictive value, was evaluated based on histopathological, clinical and imaging diagnosis. Isolated HK2 metabolically abnormal cells were subject to single-cell sequencing to verify the reliability of HK2 detection performance and to explore the molecular characteristics of UC. Results: The concordance rate of HK2 testing and cytology for detecting UC was 90.3% (102/113, Kappa=0.604). Compared with cytology, the sensitivity of HK2 was significantly higher (85.2% versus 75.6%, P=0.024). The detection sensitivity of combined HK2 testing and cytology was increased to 91.1%. HK2 testing was significantly more sensitive than cytology for diagnosing UC in the upper urinary tract (81.8% versus 65.5%, P=0.022). It was also more sensitive than cytology for diagnosing early-stage UC (82.6% versus 69.5%, P=0.375) and low-grade UC (69.6% versus 47.8%, P=0.125). Single-cell sequencing of the ten patients, whose samples were positive for HK2, demonstrated highly concordant copy number variations (CNVs) in tumor cells from the same UC patient, with heterogeneity in CNV profiles among different patients. Deletion of chromosome 8p was found in 3 of the 4 urine samples of renal pelvis UC. The 2 patients with benign lesions had no CNVs in all sequenced cells. Conclusions: The test for abnormal urinary glycolytic HK2 metabolism can assist urine cytology to improve the sensitivity of UC diagnosis, and it provides a novel and reliable approach for early detection of upper urinary tract UC and lower grade UC. Meanwhile, this study has preliminarily revealed the feasibility of single-cell sequencing in urinary samples, which is expected to improve the diagnostic specificity of HK2 testing.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.
