Objective: To assess the dynamic changes of microcirculation at acupoints in patients with primary dysmenorrhea and cold congelation and blood stasis syndrome using laser speckle blood flow imaging. Methods: Patients with primary dysmenorrhea and cold coagulation and blood stasis syndrome (primary dysmenorrhea group, n=53) and healthy female college students(control group, n=57) who met the inclusion and exclusion criteria from October 2020 to July 2022 were enrolled at Hebei University of Chinese Medicine. On the premenstrual and first day of menstruation, a laser speckle blood flow imaging system was used to measure the microcirculation blood flow perfusion on the surface of acupoints related to the conception, thoroughfare, and governor vessels, and stomach, spleen, and bladder meridians in the abdomen and lumbosacral regions. The dynamic changes in microcirculation were calculated based on the difference in average blood flow perfusion at each acupoint before and after menstruation. Receiver operating curve (ROC) analysis was used to analyze the diagnostic efficacy of dynamic changes in microcirculation on the surface of each acupoint. The microcirculation sensitization rate of acupoints was calculated. Results: Compared with the control group, the dynamic changes in microcirculation at the following acupoints in the primary dysmenorrhea group were increased (P<0.05): conception vessel (Yinjiao[CV7], Qihai[CV6], Shimen[CV5], Guanyuan[CV4]); left thoroughfare vessel (left Huangshu[KI16], left Zhongzhu[KI15], left Siman[KI14], left Qixue[KI13], left Dahe[KI12], left Henggu[KI11]); left stomach meridian (left Tianshu[ST25], left Wailing[ST26], left Qichong[ST30]); left spleen meridian (left Daheng[SP15], left Fujie[SP14]); right thoroughfare vessel (right Huangshu[KI16], right Zhongzhu[KI15], right Siman[KI14], right Qixue[KI13], right Dahe[KI12], right Henggu[KI11]); right stomach meridian (right Wailing[ST26], right Daju[ST27], right Shuidao[ST28], right Guilai[ST29], right Qichong[ST30]); and right spleen meridian (right Fujie[SP14]). The area under the ROC curve of conception vessel (Yinjiao[CV7], Qihai[CV6], Shimen[CV5], Guanyuan[CV4]), thoroughfare vessel (right Siman[KI14], left Huangshu[KI16], right Qixue[KI13], right Zhongzhu[KI15], right Dahe[KI12], left Zhongzhu[KI15], left Siman[KI14], right Huangshu[KI16], left Qixue[KI13], right Henggu[KI11], left Henggu[KI11], left Dahe[KI12]); stomach meridian (left Tianshu[ST25], right Guilai[ST29], left Wailing[ST26], right Shuidao[ST28], right Daju[ST27], right Wailing[ST26], right Qichong[ST30], left Qichong[ST30]), and spleen meridian (left Daheng[SP15], left Fujie[SP14], right Fujie[SP14]) was 0.610-0.682 (P<0.05). Compared with the control group, the sensitization rate of some acupoints in the primary dysmenorrhea group increased (P<0.05). Conclusion With the onset of menstruation, the blood flow perfusion of some acupoints in the abdomen (thoroughfare, and conception vessels, and stomach and spleen meridians) of patients with primary dysmenorrhea and cold blood coagulation and blood stasis syndrome increased, and the status of acupoints changed from a resting state to an active state. These acupoints are sensitive in patients with primary dysmenorrhea and cold blood coagulation and blood stasis syndrome and have a certain diagnostic efficacy, providing a basis for further analyzing the efficacy and mechanism of acupuncture and moxibustion to treat primary dysmenorrhea with cold blood coagulation and blood stasis syndrome.

Objective:Using bioinformatics methods to study the immune infiltration mechanism of lupus nephritis(LN)and to explore potential target Chinese medicines,which can provide new directions for clinical treatment of LN.Methods:Gene expres-sion profile microarray dataset of LN was downloaded from GEO database,differential expressed genes(DEGs)were screened using R software,and GO and KEGG enrichment analysis were performed on these DEGs.Protein interaction network analysis of DEGs was performed by applying STRING database,key genes were screened by using Cytoscape,core gene expression was validated by Nephro-seq database,and the infiltration and correlation of 22 kinds of immune cells in LN were calculated by CIBERSORT deconvolution algorithm.Finally,herbal prediction of significantly enriched immune-related biological processes and key target genes were performed by Coremine Medical database.Results:A total of 367 LN-related DEGs were obtained,of which 253 were up-regulated and 114 were down-regulated.GO was mainly enriched in response to viruses,defense response to viruses,regulation of viral life cycle,regulation of viral processes,etc;KEGG was mainly enriched in S.aureus infection,COVID-19,influenza A,complement and coagulation cascade,pertussis,etc.Ten key genes were screened:IFIT3,OAS2,MX1,OAS1,RSAD2,XAF1,ISG15,IFIT1,ITGAM and PTPRC.Immune infiltration by CIBERSORT deconvolution algorithm showed that monocytes and initial B cells were highly expressed in LN,while memory B cells,naive CD4+T cells,follicular helper T cells and resting natural killer cells were lowly expressed in LN.Immune cell correlation analysis showed a positive correlation between initial B cells and plasma cells,a positive correlation between resting natural killer cells and resting dendritic cells,a negative correlation between monocytes and regulatory T cells,and a negative correlation between resting CD4+memory T cells and monocytes.Coremine Medical predicted that Salvia miltiorrhiza,Panax notogin-seng,Scutellaria baicalensis,ginseng,honey,monkey mushroom and peony were found to be most closely related to immunity in LN.Conclusion:The development and progression of LN are results of the combined involvement of multiple genes and pathways.Mono-cytes,memory B cells,initial CD4+T cells and initial B cells are most closely associated with LN.The predicted Salvia miltiorrhiza,Panax notoginseng,Scutellaria baicalensis,ginseng,honey,monkey mushroom and peony may be used as target herbs for the poten-tial treatment of LN.

Objective:To evaluate the clinical efficacy of acupuncture in the treatment of anxiety state in patients with primary insomnia(PI). Methods:Randomized controlled trials of acupuncture treatment for PI patients with an anxiety state in Web of Science,Cochrane Library,PubMed,Excerpta Medica Database(EMBASE),China National Knowledge Infrastructure(CNKI),Wanfang Data Knowledge Service Platform(Wanfang),and Chongqing VIP Database(VIP)were retrieved by computer.The retrieval time was from each database's inception to December 30,2022.Data extraction and evaluation were performed for the included studies.The Cochrane risk of bias assessment tool was used to assess the risk of bias in each article.Meta-analysis of valid data was performed using the RevMan 5.4 software.If the outcome indicator was a categorical variable,relative risk(RR)was used as the effect size.If it was a continuous variable,mean difference(MD)was used to calculate the effect size.Each effect size was expressed as a 95%confidence interval(CI).P<0.05 was considered to indicate a statistically significant difference. Results:A total of 18 studies were included,comprising a total of 1198 patients.The findings of the meta-analysis showed that electroacupuncture had a significant advantage in improving the Hamilton anxiety scale(HAMA)score than benzodiazepines[MD=-1.61,95%CI(-2.17,-1.06),P<0.001].Acupuncture was superior to sham acupuncture[MD=-14.90,95%CI(-20.39,-9.41),P<0.001]and benzodiazepines[MD=-3.39,95%CI(-4.67,-2.12),P<0.001]in reducing the self-rating anxiety scale(SAS)score.Acupuncture was superior to sham acupuncture in reducing the insomnia severity index(ISI)score[MD=-5.61,95%CI(-6.63,-4.89),P<0.001].Acupuncture was superior to benzodiazepines[MD=0.84,95%CI(-1.42,-0.25),P=0.005]and sham acupuncture[MD=-8.39,95%CI(-8.39,-7.86),P<0.001]in improving the Pittsburgh sleep quality index(PSQI)score.Acupuncture had a better effective rate than benzodiazepines[RR=1.16,95%CI(1.08,1.25),P<0.001]and sham acupuncture[RR=8.94,95%CI(4.63,17.25),P<0.001]in treating PI. Conclusion:Acupuncture or electroacupuncture has certain therapeutic advantages over benzodiazepines and sham acupuncture in the treatment of anxiety in PI patients.However,more high-quality randomized controlled trials are needed for further verification.

Objective To observe the value of isotropic volumetric MRI for displaying perineural spread(PNS)of cranial nerve(CN)in nasopharyngeal carcinoma.Methods Eighty-seven patients with pathologically proven nasopharyngeal carcinoma were prospectively enrolled.MR scanning,including three-dimensional liver acquisition with volume acceleration-flexible(3D LAVA_Flex)image,T2WI with fat suppression(T2WI-FS),T1WI,contrast enhancement(CE)T1WI-FS of nasopharynx and neck region were performed.The displaying rates of CN PNS were evaluated and compared between 3D LAVA Flex and T2WI-FS,T1WI,CE-T1WI-FS at patient level,CN group level and neural level,respectively.Results The displaying rate of CN PNS in all 87 nasopharyngeal carcinoma patients by 3D LAVA_Flex sequence was 49.43％(43/87),higher than that of conventional MRI(30/87,34.48％,P=0.001).Among 59 patients with advanced nasopharyngeal carcinoma diagnosed with conventional sequences,the displaying rate of CN PNS was 71.19％(42/59)by 3D LAVA-Flex sequence,higher than that of conventional MRI(30/59,50.85％,P=0.001).At both patient level and posterior CN level,significant differences of the displaying rate of CN PNS were found between 3D LAVA-Flex sequence and T2WI-FS,T1WI,CE-T1WI-FS,while at CN level,the displaying rates of mandibular nerve PNS,CN Ⅸ-Ⅺ PNS in jugular foramen(P＜0.05)and CN Ⅸ-Ⅻ PNS in carotid space of 3D LAVA_Flex sequence were all significantly higher than that of T2WI-FS,T1WI and CE-T1WI-FS(all P＜0.05),of PNS of CN Ⅲ-Ⅴ in cavernous sinus were higher than that of T2WI-FS(P＜0.05),while of PNS of hypoglossal nerve were significantly higher than that of T2WI-FS and T1WI(both P＜0.05).Conclusion 3D LAVA_Flex sequence could be used to effectively display CN PNS of nasopharyngeal carcinoma.

Objective We aimed to observe the differences in the effects of different acupuncture technique on the endometrium of mice with simple endometrial hyperplasia model and to explore the potential mechanisms. Methods According to the random number tables,32 female C57BL/6J mice were divided into a blank control group,a model group,a quick needle group and a retaining needle group,with 8 mice in each group. A mouse model of simple endometrial hyperplasia was established using bilateral ovariectomy combined with estrogen loading. In the quick needle group,mice were punctured at the bilateral for "Yinbai"(SP1) points and withdrawn immediately,with the treatmeat performed once every other day for a total of 12 times. In the retaining needle group,mice were punctured at the bilateral "Yinbai"(SP1) points and the needles were retained for 15 min each time,with the treatment also performed once every other day for a total of 12 times. After the intervention,samples were collected. HE staining was used to observe morphological changes in the mouse uterine tissue;ELISA was used to detect serum estradiol level;flow cytometry was used to detect the ratio of M1 and M2 macrophages(M1/M2) and immunohistochemical method was used to measure the expression of CD86 and CD206 in uterine tissue;and Western blotting was used to detect the expression of interleukin-13 (IL-13) and interferon-γ(IFN-γ) in uterine tissue. Results The endometrium of mice in the model group showed simple hyperplasia. Compared with the blank control group,the endometrium of the model group was thickened (P<0.01);the level of estradiol in the serum was increased (P<0.01);M1/M2 in uterine tissues was decreased (P<0.01),the expression of CD86 was decreased (P<0.01),and the positive expression of CD206 was increased (P<0.01);and the level of IFN-γ protein expression in uterine tissues was decreased (P<0.01),and the expression of IL-13 protein was increased (P<0.01). Compared with the model group,the endometrial thicknesses of the quick needle group and the retaining needle group were reduced (P<0.05),the levels of estradiol in serum were reduced (P<0.05),M1/M2 in uterine tissues increased (P<0.01),and the reduction of CD206 positive expression,and IL-13 protein expression reduced (P<0.01);the level of CD86 positive expression,IFN-γ protein expression increased (P<0.01). Compared with the quick needle group,IL-13 protein expression increased in the retaining needle group (P<0.01).Conclusion Both quick needle and retaining needle may be through the regulation of the expression of IFN-γ and IL-13,thus prompting the polarization of macrophages from M2 to M1 type,inhibiting the pro-cell proliferative ability and tissue repair ability of M2 type macrophages,thus reducing the degree of endometrial hyperplasia,and the quick needle group was superior to the retaining needle group in regulating the expression of IL-13.

Objective:To investigate the efficacy of acellular allogeneic dermal matrix (ADM) combined with autologous razor-thin scalp grafts in scar rehabilitation.Methods:A retrospective study was conducted on patients who underwent skin grafts transplantation to repair scar in the Department of Burns and Plastic Surgery of the First People’s Hospital of Chenzhou from July 2015 to December 2021. All the patients were divided into the observation group and the control group according to surgical methods. The observation group was treated with ADM combined with autologous razor-thin scalp grafts to repair the wound after scar resection, and the control group was treated with split-thickness skin grafts (STSGs) to repair the wound. Efficacy evaluation: On the 1st, 7th and 14th day after surgery, the patients in the two groups scored the pain degree of the donor sites through the visual analogue scale (VAS), with a score of 0 indicating no pain and a score of 10 indicating severe pain. The grid method was used to measure the surviving area of the skin and calculate the surviving proportion of the skin grafts. The wound healing time in donor and recipient sites were recorded. The postoperative complication was recorded, and the incidence of complications was calculated. Scars in donor and recipient sites were observed at the 3rd, 6th, 9th and 12th month after surgery, and the scars in recipient sites were scored by the Vancouver scar scale (VSS), with a total score of 0-13 points, and the higher the score, the more serious the scars were. SPSS 22.0 software was used for statistical analysis of the data. The normally distributed continuous data were represented as Mean±SD, and analyzed by t-test, and the non-normally distributed continuous data were represented as M ( Q1, Q3), and the Wilcoxon rank-sum test was used for comparison between groups. Enumeration data were expressed as examples and (or) percentages, and chi-square test was used for comparison between groups. The differences were considered statistically significant for probability values P<0.05. Results:A total of 50 patients, including 28 males and 22 females, aged (38.5±13.9) years, were enrolled in the observation group, and the wound area caused by scar resection and release was (70.4±17.7) cm 2. The scars were on upper limb in 16 cases, lower limb in 15 cases, trunk in 11 cases, neck in 8 cases. The control group included 50 patients, 30 males and 20 females, aged (34.8±14.6) years, and the wound area caused by scar resection and release was (66.2±16.5) cm 2. The scars were on upper limb in 15 cases, lower limb in 11 cases, trunk in 13 cases, neck in 11 cases. There was no significant difference in gender composition, age, skin graft site and the wound area caused by scar resection and release between these two groups ( P > 0.05). On the 1st, 7th and 14th day after surgery, the VAS scores of the observation group were 6.35 (5.11, 7.67) points, 4.95 (3.63, 6.46) points and 0.73 (0.18, 1.39) points, while the control group were 8.25 (7.14, 9.19) points, 7.00 (5.45, 8.06) points and 0.80(0.20, 1.55)points, respectively. The VAS score of the observation group was lower than that of the control group on the 1st and 7th day after surgery ( Z=-4.53, -3.86, both P < 0.001), and there was no significant difference in VAS score between the two groups on the 14th day after surgery ( P > 0.05). There was no significant difference between the two groups in terms of the survival ratio of skin grafts [(95.6±2.1) % vs. (95.8±2.3) %] ( P>0.05) and the postoperative incidence of complications [18% (9/50) vs. 10% (5/50)] ( P>0.05). The wound healing time in the donor sites in both groups were (6.80±0.88) days, (13.30±1.83) days ( t=-22.70, P<0.001), while the wound healing time in the recipient sites in both groups were 14.33 (12.73, 15.76) days and 8.91 (7.76, 10.67) days ( Z=-7.31, P<0.001). The average follow-up time was 21.8 months, the observation group had no scar formation at the donor site, while the control group had different degrees of scar hyperplasia. There was no significant difference in VSS scores between the two groups at the 3rd and 6th month after surgery ( P>0.05), while the VSS scores of the observation group at 9th and 12th month after surgery were 5.96 (4.81, 7.15) points and 5.85 (4.81, 6.75) points, which were significantly lower than those of in the control group [7.04(5.93, 8.14)points, 6.92(5.81, 8.06)points] ( Z=-2.82, P=0.005; Z=-3.54, P<0.001). Conclusion:The use of ADM combined with autologous razor-thin scalp graft to repair the wound after scar resection can effectively improve the appearance and function of the repair area, and reduce the pain and avoid scar hyperplasia in the donor sites.

Objective To explore the correlation of serum microRNA-499a-5p (miR-499a-5p), fibroblast growth factor 9 (FGF9) and inflammatory factors with the severity and prognosis of acute lung injury (ALI) caused by sepsis. Methods A total of 151 septic patients were selected for the study. They were divided into sepsis with acute lung injury (ALI) group (68 cases) and general sepsis group (83 cases) based on the occurrence of ALI. According to the oxygenation index, septic patients with ALI were further categorized into mild (23 cases), moderate (26 cases), and severe (19 cases) groups. The survival status of septic patients with ALI was assessed within 28 days, and they were divided into good prognosis group (43 cases) and poor prognosis group (25 cases). Additionally, 151 healthy individuals undergoing physical examinations during the same period were selected as the control group. The differences and correlations among miR-499a-5p, FGF9 and inflammatory factors in each group were analyzed. The predictive efficacy of serum miR-499a-5p and FGF9 in patients with sepsis complicated with ALI was analyzed by receiver operating characteristic (ROC) curve. Results The levels of miR-499a-5p and FGF9 in the mild, moderate, and severe groups showed significant decrease in a sequential manner, while the inflammatory factors interleukin-1 (IL-1), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and C-reactive protein (CRP) levels showed significant increase in a sequential manner (P < 0.05). The miR-499a-5p and FGF9 levels in the poor prognosis group were significantly lower than those in the good prognosis group, while the IL-1, IL-6, TNF-α, and CRP levels were significantly higher in the poor prognosis group (P < 0.05). In patients with sepsis and ALI, miR-499a-5p and FGF9 were negatively correlated with IL-1, IL-6, TNF-α, and CRP levels (P < 0.05); miR-499a-5p could positively regulate FGF9 expression (P < 0.05). The diagnostic efficacy of predicting the prognosis of septic patients with ALI using a combination of miR-93 and miR-135a was significantly higher than that of individual prediction (P < 0.05). Conclusion The levels of miR-499a-5p, FGF9 and inflammatory factors are associated with the severity and prognosis of ALI in patients with sepsis. The miR-499a-5p and FGF9 may serve as potential biomarkers for the evaluation of prognosis in septic patients with ALI.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Objective:To explore the repair methods of complex facial defect wounds involving paranasal sinuses and their clinical effectiveness.Methods:A retrospective observational study was conducted. From January 2020 to May 2022, 5 patients admitted to the Department of Burns and Plastic Surgery of Xiangya Hospital of Central South University and 4 patients admitted to the Department of Burns and Plastic Surgery of Chenzhou First People's Hospital with complex facial defect wounds involving paranasal sinuses met the inclusion criteria, including 6 males and 3 females, aged 35-69 years, including 4 patients with titanium mesh exposure combined with paranasal sinuses injury and 5 patients with tumor involving paranasal sinuses. After an adequate assessment of the damage by a multiple discipline team, titanium mesh removal, paranasal sinus debridement, and paranasal sinus mucosa removal were performed in patients with exposed titanium mesh, and radical tumor resection was performed in patients with tumors, with postoperative skin and soft tissue defects areas of 5.0 cm×2.5 cm to 18.0 cm×7.0 cm, anterior paranasal sinus wall defects/absence areas of 3 cm×2 cm to 6 cm×4 cm, and sinus cavity depths of 1 to 4 cm. Depending on the perforator course of the descending branch of the lateral circumflex femoral artery, the anterolateral femoral chimeric flap or anterolateral femoral myocutaneous flap (with flap area of 9 cm×4 cm to 19 cm×8 cm, muscle size of 5 cm×3 cm×3 cm to 11 cm×6 cm×3 cm) was transplanted to repair the defect, and the donor site wound was sutured directly. The type of tissue flap transplanted, the blood vessel of the recipient area, and the vascular anastomosis way during the operation, the recovery of the donor and recipient areas and the occurrence of complications after operation were observed. The appearance and blood supply of the recipient area and the recurrence of ulcers and tumors were followed up.Results:The anterolateral femoral myocutaneous flap transplantation was performed in 6 patients, and the anterolateral femoral chimeric flap transplantation was performed in 3 patients. The blood vessels in recipient areas were facial arteries and veins in 3 cases and superficial temporal arteries and veins in 6 cases. The superficial temporal arteries and veins were bridged with blood vessels in tissue flaps by flow-through way in 2 patients, and end-to-end anastomosis of blood vessels in donor and recipient areas was performed in 7 patients. After operation, all the tissue flaps survived, and the facial defect wounds were well repaired without cerebrospinal fluid leakage or paranasal sinus secretion leakage, no intracranial infection occurred, and the wounds in donor areas were healed well. Follow-up of 6-35 months after operation showed that all the patients had good blood supply in the recipient area, and the shape was acceptable; 4 patients with exposed titanium mesh had no recurrence of ulceration, and 5 patients with tumor had no local tumor recurrence or metastasis.Conclusions:Based on an adequate assessment of the extent of paranasal sinuses involved in the facial wound and the nature of the defect, good clinical effects can be achieved by using the anterolateral femoral muscle flap or the anterolateral femoral chimeric flap transplantation to repair complex facial defect wounds with open paranasal sinuses.
