Objective To investigate the expression change of serum antioxidant markers in cranofacial herpes zoster and its relationship with clinical severity and postherpetic neuralgia(PHN).Methods Totally 109 cases of cranofacial herpes zoster(cranofacial group)and 169 cases of non-cranofacial herpes zoster(non-cranofacial grlup)hospitalized in the Department of Dermatology in the Second Affiliated Hospital of Nanjing Medical University and 200 cases of health check-ups without underlying diseases(healthy control group)from January 2022 to December 2023 were selected,and the serum antioxidant markers including uric acid(UA),total bilirubin(TBIL),and albumin(ALB)of the patients in the three groups group were compared.Meanwhile,the relationship between these markers and clinical severity and PHN of cranofacial herpes zoster was assessed.Results The serum levels of UA,TBIL and ALB in the cranofacial group and non-cranofacial were significantly lower than those in the healthy control group(P＜0.05).Serum UA,TBIL and ALB levels in cranofacial group were significantly lower than those in non-cranofacial group(P＜0.05),and were nega-tively correlated with disease severity(P＜0.05).Serum UA,TBIL and ALB levels in cranofacial group were independent influencing factors for the occurrence of PHN(P＜0.05),and had predictive value for PHN in cranofacial herpes zoster(P＜0.05).Conclusion Reactivation of cranofacial herpes zoster virus,acute nerve injury and PHN may all be related to the low antioxidant status of the body,and the antioxidant biomarkers UA,TBIL and ALB may be protective factors for herpes zoster,but more studies are needed to clarify the un-derlying mechanisms.

Objective:Uterine adhesion is mainly caused by endometrial injury,leading to poor postoperative pregnancy outcome.Therefore,preoperative evaluation on uterine cavity,especially endometrial condition,is very necessary.This study aims to explore the correlation between preoperative three-dimensional transvaginal ultrasound(3D-TVS)imaging characteristics and postoperative pregnancy outcomes after hysteroscopic adhesiolysis(HA). Methods:A total of 401 patients,who underwent HA surgery from February 22,2018 to October 31,2018 at the Third Xiangya Hospital of Central South University or Changsha Jiangwan Hospital,were enrolled,and we collected data regarding the preoperative 3D-TVS imaging characteristics and followed up their postoperative pregnancy outcomes.Correlation analysis and univariate and multivariate logistic regression analysis were performed between imaging features and pregnancy outcomes(live and non-live birth outcomes)in patients with intrauterine adhesion. Results:The results of correlation analysis showed that endometrial thickness,endometrial echo,visible tubal openings,endometrial blood flow,intercornual distance,and endometrial peristalsis were correlated with the live birth rate(all P<0.05).Logistic regression analysis revealed that in the HA patients with the live birth,the endometrial thickness was thicker(P<0.001),endometrial echo was more homogeneous(P<0.001),the number of tubal openings was more(P<0.001),the intercornual distance was wider(P<0.05),the endometrial blood flow,and irregular cases of endometrial peristaltic waves were more and cases of deficiency were fewer(both P<0.01)than those in the non-live birth group. Conclusion:Preoperative 3D-TVS imaging performance is closely related to pregnancy outcomes of HA patients,and preoperative 3D-TVS can be used to predict pregnancy outcomes after HA.

BACKGROUND: There is no report on the treatment of suppurative discitis with posterior microendoscopic discectomy, antibiotic artificial bone implantation and one-stage percutaneous pedicle screw fixation. OBJECTIVE: To evaluate the clinical effectiveness of posterior microendoscopic debridement, antibiotic artificial bone implantation and one-stage percutaneous pedicle screw fixation for pyogenic spondylodiscitis. METHODS: Thirty-one patients with suppurative discitis admitted at the Department of Spinal Surgery, the First Affiliated Hospital of Guangzhou Medical University from January 2014 to December 2017, including 17 males and 14 females, aged 28-78 years, were included. All the patients underwent posterior microendoscopic lesion clearance and antibiotic artificial bone grafting and one-stage percutaneous pedicle screw fixation. The erythrocyte sedimentation rate and C-reactive protein levels were detected at postoperative follow-up. The Visual Analog Scale and the Japanese Orthopaedic Association scores were used for detection. RESULTS AND CONCLUSION: (1) All the surgical operations of the 31 patients were successfully completed and all patients had immediate relief of low back pain and lower extremity radiation pain. They were able to move ground wearing a waistband at 1-4 days postoperatively. (2) Thirty-one patients were followed up for 9-18 months. All patients had a significant decrease in C-reactive protein and erythrocyte sedimentation rate at 1 week after surgery, and C-reactive protein and erythrocyte sedimentation rate were in the normal range at 1, 3, and 6 months postoperatively. (3) The Visual Analog Scale scores of all patients at 1 week of follow-up were significantly lower than those before surgery (P < 0.05) , and the Japanese Orthopaedic Association scores were significantly higher than those before surgery (P < 0.05) . (4) In the follow-up examination of CT and MRI, there was no recurrence, pseudoarticular formation or internal fixation loosening. (5) These results suggest that posterior microendoscopic discectomy, antibiotic artificial bone implantation combined with one-stage percutaneous pedicle screw fixation for treating suppurative discitis can result in little trauma, few bleeding and rapid pain relief, and patients can move to the ground early. The operation method has a good clinical effect.

Objective To investigate the effect of nicotinamide mononucleotide (NMN) on insulin secretion and gene expressions of pancreatic and duodenal homeobox 1 ( PDX-1 ) and forkhead box-containing protein O-1 ( FoxO1 ),which were important transcription factors for insulin secretion.Methods Insulin secretion level in RIN-m5f cells was detected by rat insulin ELISA detection kit.The mRNA expression levels of PDX-1 and FoxO1 in RIN-m5f cells were analyzed by real-time PCR.The protein expression of PDX-1 was measured by Western blot.Results Insulin secretion levels in RIN-m5f cells treated with repaglinide ( 10 nmol/L) plus NMN ( 100 μnol/L) was significantly higher than those in the blank control,the DMSO control group,and the NMN (50μmol/L) treated group (P ＜0.05 ).The mRNA expression levels of PDX-1 in RIN-m5f cells treated with NMN ( 10,50 and 100 μmol/L) for 36 h were significantly higher than those in the control group (P ＜0.05,P ＜ 0.01,and P ＜ 0.001,respectively).There was marked differences in the mRNA expression levels of PDX-1 among different concentrations of NMN (P ＜0.001 ),but no significant differences in the mRNA expression level of FoxO1 ( P ＞ 0.05).No significant difference was found in the protein expression levels of PDX-1 in RIN-m5f cells treated by NMN (50,100,and 200 μmol/L) for 36 or 48 h compared with the control group (P ＞ 0.05).Conclusion NMN can stimulate insulin secretion and upregulate the mRNA expression of PDX-1 in RIN-m5f cells.

Objective To explore the association between rs3758539G-803A and rs10882283 T-179G polymorphism of retinol binding protein 4 (RBP4) and rosiglitazone response in Chinese type 2 diabetes mellitus (T2DM) patients.Methods A total of 472 Chinese T2DM patients and 198 healthy subjects were enrolled to identify G-803A and T-179G genotypes using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP ).assay.Forty-two T2DM patients with different G-803A or T-179G genotypes were selected to undergo a 12-week rosiglitazone treatment (4 mg/d).Serum fasting plasma glucose (FPG),postprandial plasma glucose (PPG),fasting serum insulin (FINS),glycated hemoglobin (HbAlc),postprandial serum insulin ( PINS),triglyceride (TG),low-density lipoprotein-cholesterol ( LDL-c),and high-density lipoprotein-cholesterol (HDL-c) were determined before and after the rosiglitazone treatment.Results T2DM patients with RBP4 G-803A GG genotype showed lower TG and LDL-c concentrations compared with that in the GA +AA genotype subjects.T2DM patients with RBP4 T-179G TT genotype showed lower waist-to-hip ratio (WHR),FPG and FINS values compared with that in the TG + GG genotype individuals.Patients with GG genotype of RBP4 G-803A had an enhanced rosiglitazone efficacy on FPG and FINS compared with that in the GA + AA genotype group.Patients with RBP4 T179G TG + GG genotype showed an enhanced rosiglitazone efficacy on HbAlc level compared with that in the TT genotype group.Conclusion RBP4 G-803A and T-179G polymorphism might be associated with the development of T2DM and affect the therapeutic efficacy of rosignitazone in Chinese T2DM patients.

To report a case of retinoic acid syndrome due to tretinoin in the treatment of psoriasis.A 32-year-old male patient presented with psoriasis vulgaris for more than 10 years.In recent 10 years,he experienced erythema,plaques covered with multi-layered scales on the scalp,trunk,extremities accompanied by pruritus.The patient was diagnosed as psoriasis and given long-term treatment with oral vitamins,traditional Chinese medicine,and topical drugs,which resulted in a status of remission and exacerbation.Half a year prior to the presentation,the patient was given acitretin 10 mg twice daily due to the exacerbation of condition;20 days later,the dose increased to thrice daily;after another 30 days,the lesions were improved,and the frequency decreased to twice daily again;finally,a disappearance of the lesions was achieved after half a year of maintenance treatment with acitretin 10 mg twice daily.One week prior to the presentation,the treatment strategy was altered from acitretin to viaminate 50 mg twice daily;after three days with viaminate,the patient experienced a sudden worsening of psoriatic lesions with an obvious inflammatory reaction;subsequently,the lesions rapidly spread to the whole body surface and fused into large patches,accompanied with the following signs:marked edema,massive desquamating,high fever (＞39℃),hypotension,respiratory distress,pulmonary edema,pleural and pericardial effusions,renal dysfunction,peripheral blood leukocytosis.The patient was diagnosed as retinoic acid syndrome(RAS).After given oral glucocorticoid,symptomatic and supportive treatment,he experienced a relief of symptoms.These findings indicate that RAS is an entity with an abrupt onset and poor prognosis.For patients with RAS,early diagnosis and prompt management with corticosteroids,symptomatic and supportive treatments are essential to avoid potential fatal complications.

To compare the effects of polysaccharide nucleic acid fraction of bacillus calmette guerin (BCG-PSN) and thymopeptides on T-lymphocytes of normal and immunosuppressed mice, CD4+ and CD8+ T-lymphocyte subsets of single nucleic cell in thymus, spleen and peripheral blood were detected successively by flow cytometry after application of BCG-PSN and thymopeptides. Meanwhile, CD4+/CD8+ ratio was also calculated. The results showed that both BCG-PSN and thymopeptides could decrease the proportion of CD4+ CD8+ T-lymphocyte subsets in the thymus, at the same time increase CD4+ T-lymphocyte, CD8+ T-lymphocyte proportion in the three tissues. The fluctuation in amplitude was greater in thymopeptides group than that in BCG-PSN group. It is concluded that acting location of thymopeptides is in thymus, its stimulating action is stronger than that of BCG-PSN, while BCG-PSN not only accelerates the differentiation in thymus, but also has some direct stimulation to peripheral CD4+ T-lymphocytes, and can maintain CD4+/CD8+ ratio within normal range. So, BCG-PSN is safer.

To study the mechanism of Condyloma acuminatum (CA) recurrence, and the association of CA recurrence with the ability of the host derived lymphoblastoid cell lines (LCL) stimulated by LPS to produce tumor necrosis factor (TNF), EBV-transformed B LCL were used as TNF producing cells. The ability of LCL stimulated by LPS to produce TNF was measured by bioassay. The results showed that the LCL from CA patients (including recurrent and non-recurrent CA patients) produced similar level of TNF stimulated by LPS to that of normal controls (29.54% +/- 11.28% vs 34.31% +/- 11.46%, P = 0.1498). The LCL of CA recurrent patients produced significantly lower amount of TNF than that of non-recurrent CA patients (23.72% +/- 7.41% vs 37.33% +/- 11.10%, P = 0.0032). Compared with the normal controls, CA recurrent patients showed a decreased ability to produce TNF (23.72% +/- 7.41 vs 34.31% +/- 11.46, P = 0.0054), whereas CA non recurrent patients had the similar ability to the controls (37.33% +/- 11.10 vs 34.31% +/- 11.46, P = 0.4914). It was concluded that the onset of CA was not relevant to the individual's ability to produce TNF. But the recurrence of CA was associated with the ability to produce TNF. It was also indicated that the TNF involved cellular immunity might play an important role in the clearance of the residual HPV by the host after treatment.

Objective To investigate the correlation between the relapse of condyloma acuminatum(CA)and the potential capability of tumor necrotic factor (TNF) production of the host′s peripheral blood leukocytes. Methods Forty-two CA patients and 58 normal controls were enrolled in this study. CA relapse was diagnosed clinically. EB virus-transformed B lymphoblastoid cell line(LCL)were used as TNF producing cells. The TNF producing capability of LCL was measured by bioassay using L929 (a TNF sensitive tumor cell line) as target cells. The LCL were stimulated with LPS to produce TNF. Results The average level of TNF production of LCL from all CA patients (including recurrent and non-recurrent CA patients) was similar to that of normal controls (30.14% ? 12.27 vs 34.06% ? 12.06,P = 0.1136). However, the level of TNF production of LCs from recurrent CA patients was significantly less than that from non-recurrent CA patients (24.75% ? 7.51 vs 36.62% ? 10.96,P = 0.00016). Compared with that of normal controls, recurrent CA patients showed a lower capability to produce TNF (24.75% ? 7.51 vs 34.06% ? 12.06,P = 0.00054), whereas non-recurrent CA patients showed a similar capability to normal controls (36.62% ? 10.96 vs 34.06% ? 12.06,P = 0.3517). Conclusions These results indicate that the cellular immune mechanism might play an important role in the clearance of the residual HPV from the host, in which TNF is involved.
