This study aims to investigate the effect of Chaijin Jieyu Anshen Formula on the neuroinflammation of rats with insomnia complicated with depression through the regulation of triggering receptor expressed on myeloid cells 2(TREM2)/complement protein C1q signaling pathway. Rats were randomly divided into a normal group, a model group, a positive drug group, as well as a high, medium, and low-dose groups of Chaijin Jieyu Anshen Formula, with 10 rats in each group. Except for the normal group, the other groups were injected with p-chlorophenylalanine and exposed to chronic unpredictable mild stress to establish the rat model of insomnia complicated with depression. The sucrose preference experiment, open field experiment, and water maze test were performed to evaluate the depression in rats. Enzyme-linked immunosorbent assay was employed to detect serum 5-hydroxytryptamine(5-HT), dopamine(DA), and norepinephrine(NE) levels. Hematoxylin and eosin staining and Nissl staining were used to observe the damage in nucleus accumbens neurons. Western blot and immunofluorescence were performed to detect TREM2, C1q, postsynaptic density 95(PSD-95), and synaptophysin 1(SYN1) expressions in rat nucleus accumbens, respectively. Golgi-Cox staining was utilized to observe the synaptic spine density of nucleus accumbens neurons. The results show that, compared with the model group, Chaijin Jieyu Anshen Formula can significantly increase the sucrose preference as well as the distance and number of voluntary activities, shorten the immobility time in forced swimming test and the successful incubation period of positioning navigation, and prolong the stay time of space exploration in the target quadrant test. The serum 5-HT, DA, and NE contents in the model group are significantly lower than those in the normal group, with the above contents significantly increased after the intervention of Chaijin Jieyu Anshen Formula. In addition, Chaijin Jieyu Anshen Formula can alleviate pathological damages such as swelling and loose arrangement of tissue cells in the nucleus accumbens, while increasing the Nissl body numbers. Chaijin Jieyu Anshen Formula can improve synaptic damage in the nucleus accumbens and increase the synaptic spine density. Compared to the normal group, the expression of C1q protein was significantly higher in the model group, while the expression of TREM2 protein was significantly lower. Compared to the model group, the intervention with Chaijin Jieyu Anshen Formula significantly downregulated the expression of C1q protein and significantly upregulated the expression of TREM2. Compared with the model group, the PSD-95 and SYN1 fluorescence intensity is significantly increased in the groups receiving different doses of Chaijin Jieyu Anshen Formula. In summary, Chaijin Jieyu Anshen Formula can reduce the C1q protein expression, relieve the TREM2 inhibition, and promote the synapse-related proteins PSD-95 and SNY1 expression. Chaijin Jieyu Anshen Formula improves synaptic injury of the nucleus accumbens neurons, thereby treating insomnia complicated with depression.

Objective Based on U.S.Food and Drug Administration Adverse Event Reporting System(FAERS)database,the signal mining of tizanidine adverse drug events(ADEs)was conducted to explore the occurrence characteristics of ADE,hoping to provide references for the safe clinical application of tizanidine.Methods The reporting odds ratio(ROR)and medicines and healthcare products regulatory agency methods(MHRA)were used to analyse the ADE of tizanidine using FAERS registration data from the first quarter of 2004 to the second quarter of 2022.After valid signals were obtained,the MedDRA was used for translation and system organ classification.Results A total of 7 135 reports of tizanidine ADE were obtained,including 1 732 patients,1 304 ADE types were involved.According to the results of 2 ADE signal mining methods,at the preferred term(PT)level,177 signals were detected.There were 32 PT signals not included in the drug instructions,including potassium wasting nephropathy,cardio-respiratory arrest,and foetal growth restriction etc.In 1 732 patients,the number of ADE cases of female was 2.37 times that in male(1 057 vs.446),and the age group between 40 and 64 accounted for a large proportion(36.03％).The highest proportion(32.79％)reported by consumers.The system organ class involved mainly included various neurological diseases and psychosis.The median time to onset of tizanidine-related ADEs was 75 d(interquartile range:28-223 d),but it was necessary to be vigilant that ADE may still occur 1 year after starting the drug(13.38％).Conclusion This study aims to suggest that clinical application of tizanidin-related ADE should be paid full attention to the occurrence of ADE such as potassium-wasting nephropathy and suicidally completed,as well as key populations such as women and patients of 40-64 years old.

The odor fingerprint of Pollygonati Rhizoma samples with different mildewing degrees was analyzed and the relationship between the odor variation and the mildewing degree was explored. A fast discriminant model was established according to the response intensity of electronic nose. The α-FOX3000 electronic nose was applied to analyze the odor fingerprint of Pollygonati Rhizoma samples with different mildewing degrees and the radar map was used to analyze the main contributors among the volatile organic compounds. The feature data were processed and analyzed by partial least squares discriminant analysis(PLS-DA), K-nearest neighbor(KNN), sequential minimal optimization(SMO), random forest(RF) and naive Bayes(NB), respectively. According to the radar map of the electronic nose, the response values of three sensors, namely T70/2, T30/1, and P10/2, increased with the mildewing, indicating that the Pollygonati Rhizoma produced alkanes and aromatic compounds after the mildewing. According to PLS-DA model, Pollygonati Rhizoma samples of three mildewing degrees could be well distinguished in three areas. Afterwards, the variable importance analysis of the sensors was carried out and then five sensors that contributed a lot to the classification were screened out: T70/2, T30/1, PA/2, P10/1 and P40/1. The classification accuracy of all the four models(KNN, SMO, RF, and NB) was above 90%, and KNN was most accurate(accuracy: 97.2%). Different volatile organic compounds were produced after the mildewing of Pollygonati Rhizoma, and they could be detected by electronic nose, which laid a foundation for the establishment of a rapid discrimination model for mildewed Pollygonati Rhizoma. This paper shed lights on further research on change pattern and quick detection of volatile organic compounds in moldy Chinese herbal medicines.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

Objective: This study aimed to determine the efficacy of dose-enhanced immunochemotherapy followed by autologous peripheral blood stem cell transplantation (ASCT) in young patients with newly diagnosed high-risk aggressive B-cell lymphoma. Methods: A retrospective study was conducted to examine the clinical and survival data of young patients with high-risk aggressive B-cell lymphoma who received dose-enhanced immunochemotherapy and ASCT as first-line treatment between January 2011 and December 2018 in Blood Diseases Hospital. Results: A total of 63 patients were included in the study. The median age range was 40 (14-63) years old. In terms of the induction therapy regimen, 52 cases received R-DA-EP (D) OCH, and the remaining 11 received R-HyperCVAD/R-MA. Sixteen (25.4% ) patients achieved partial response in the mid-term efficacy assessment, and ten of them were evaluated as complete response after transplantation. The median follow-up was 50 (8-112) months, and the 3-year progression-free survival (PFS) rate and overall survival (OS) rate were (83.9±4.7) % and (90.4±3.7) % , respectively. Univariate analysis demonstrated that age-adjusted international prognostic index ≥2 scores was a negative prognostic factor for OS (P=0.039) , and bone marrow involvement (BMI) was an adverse prognostic factor for OS (P<0.001) and PFS (P=0.001) . However, multivariate analysis confirmed that BMI was the only independent negative predictor of OS (P=0.016) and PFS (P=0.001) . Conclusions: The use of dose-enhanced immunochemotherapy in combination with ASCT as first-line therapy in the treatment of young, high-risk aggressive B-cell lymphoma results in good long-term outcomes, and BMI remains an adverse prognostic factor.

ObjectiveTo summarize the effect of visual electrophysiological diagnosis and treatment technology on postoperative urinary incontinence in early intervention after transurethral enucleation and resection of the prostate （TUERP）. MethodsTotally 86 patients with benign prostatic hyperplasia （BPH） who underwent TUERP in the Puji Branch Hospital of Dongguan People's Hospital from December 2020 to June 2022 were selected as the treatment group， who received electrophysiological treatment after postoperative removal of the catheter on the 6th day after surgery， while 79 cases who received no electrophysiological treatment after surgery were selected as the control group. The urinary incontinence rates of the two groups on the 6^th day， at 1 month and 3 months after surgery were observed. ResultsThere was no statistical difference between the two groups in the preoperative basic data. The rates of urinary incontinence after removal of the catheter in the two groups on the 6^th day after surgery were 13 cases （15.1%） in the treatment group and 12 cases （15.2%） in the control group. There was no significant difference between the two groups （P >0.05）， and the overall postoperative urinary incontinence rate in the two groups was 15.2% （25/165）. At one month after surgery， only 4 cases （4.65%） had slight urinary incontinence in the treatment group， while 13 cases （16.5%） in the control group still had urinary incontinence， and the difference between the two groups was statistically significant （ P=0.019）. After follow-up to three months after operation， there was no case of urinary incontinence in the treatment group， and there were still 7 cases （8.86%） of urinary incontinence in the control group. The difference between the two groups was statistically significant （P=0.005）. ConclusionThe early intervention of visual electrophysiological diagnosis and treatment technology can effectively prevent the occurrence of urinary incontinence after TUERP， and has good value in clinical application.

The value of the "touching-bone" acupuncture technique in clinical application was explained through the investigation on the origin of the theory of the "touching-bone" acupuncture technique, the analysis on the characteristics of acupoint selection, the introduction of clinical characteristics and the discussion on the mechanism of acupuncture in treatment. The "touching-bone" acupuncture technique refers to deep needling method, originated from the short needling and needling of the ancient needling methodslisted in the . The target points are the reaction sites on meridian near to bone and the attachments of soft tissues on bone. During the needle insertion, the needle tip is thrust deeply to the bone or the needle body is closely attached to the bone so as to stimulate periosteum specifically. This needling technique contributes to the satisfactory effect on spasmodic, deep-located and intractable pain disorder, motor system diseases, mental diseases and cerebral diseases, etc. Hence, this acupuncture technique deserves to be promoted in clinical application and explored in research.

Objective: To assess the feasibility and prognostic value of the minimal residual disease (MRD) evaluated by multiparameter flow cytometry (MFC) in the newly diagnosed multiple myeloma (MM) patients of China. Methods: Clinical data of 106 consecutively newly diagnosed MM patients with MRD data were retrospectively analyzed in a single center in China from June 2013 to June 2015. Results: ① Of 106 patients, 48 (45.3%) achieved MRD negativity. The median time to MRD-negative was 3 months. More patients undergoing autologous stem cell transplantation (ASCT) achieved MRD negativity compared with non-ASCT patients (62.2% vs 36.2%, χ(2)=6.536, P=0.011). ② Of 48 patients in complete remission (CR), 7 (14.6%) was MRD positive, 5 of them showed disease progression (PD) during the follow-up, and 3 died. The median progression free survival (PFS) was 19 months, and the median overall survival (OS) was 28 months, both were significantly shorter than the CR patients with MRD-negative (P<0.05). ③At a median follow-up of 38 months, MRD-negative patients showed significantly superior outcomes compared with MRD positive ones, the PFS was not reach versus 17 months and the OS was not reach for both (P<0.001). Patients were grouped into 4 categories according to their MRD levels: 1% or higher, 0.1% to less than 1%, 0.01% to less than 0.1%, or negative. It showed that the outcomes (PFS and OS) tended to be improved along with the tumor depletion. ④ Multivariate prognostic analysis showed that MRD was a powerful independent prognostic factor for PFS[HR=0.133 (95% CI 0.062-0.288) , P<0.001] and OS[HR=0.156 (95% CI 0.050-0.484) , P=0.001]. According to MRD and cytogenetics, the patients were classified into 4 groups. High risk patients with MRD negative presented a significantly better outcome than high risk patients with MRD-positive, and a similar one to the standard risk patients with MRD-negative. Conclusions: MRD negativity by MFC was more popular in MM patients undergoing ASCT. MRD was an independent prognostic factor in MM. And the prognosis of MM patients can be stratified according to the level of MRD. MRD-negative patients with high risk cytogenetics presented a similar outcome to the standard risk ones. MRD by MFC should therefore be considered more widely applied in the clinic.

Objective: To explore the prognostic factors in newly diagnosed multiple myeloma (NDMM) patients with 1q21 amplification/gain treated with bortezomib-based regimens followed by autologous hematopoietic stem cell transplantation (ASCT) . Methods: We retrospectively assayed 35 NDMM patients with 1q21 amplification/gain who received bortezomib-based chemotherapy followed by ASCT and maintenance therapy between January 2008 and August 2015. Results: ①The median age of 35 patients were 49(33-63)years old. Ratio of male to female was 22∶13. Monosomy1q21 amplification/gain was only seen in 3(8.6%) patients, the other 32 patients were with additional cytogenetic abnormalities including 13q14 deletion, t(11,14), t(4,14), t(14,16), 17p deletion and complex karyotype aberrations. ②The complete remission (CR) rate was 57.0% (20/35), the very good partial remission(VGPR) rate was 37.1%(13/35) and the partial remission (PR) rate was 5.7%(2/35) after ASCT. At a median follow-up of 24 (8-85) months, 3-year estimated progression free survival (PFS) and overall survival (OS) rate were (66.5±9.7)% and (69.6±9.9)%, respectively. ③As 13 patients with high-risk cytogenetic abnormalities, the median PFS and OS time was 26 and 28 months. The 3-year estimated PFS and OS was (28.0±15.9)% and (36.5±16.4)%, respectively. Another 22 patients without other high-risk cytogenetic abnormalities, the median PFS and OS time was 54 months and not reached. The 3-year estimated PFS and OS was (71.5±12.7)% and (92.3±7.4)% in this group, respectively. The presence of additional other high-risk cytogenetic abnormalities resulted in significantly shortened PFS (χ(2)=5.404, P=0.020) and OS (χ(2)=7.596, P=0.006) compared with no high-risk cytogenetic patients. Conclusion: NDMM patients with isolated1q21 amplification/gain were rarely and usually had additional other cytogenetic abnormalities. The outcomes in this group treated with bortezomib-based chemotherapy followed by ASCT and maintenance therapy were satisfied, additional other high-risk cytogenetic abnormalities made PFS and OS further shortened.
