Objective:To investigate the clinical application value of commonly used preoperative indicators of sarcopenia in predicting postoperative pneumonia in patients aged 70 years and above with esophageal cancer.Methods:A retrospective analysis was conducted on the clinical data of 398 elderly patients(≥70 years old)with esophageal squamous cell carcinoma who underwent thoracic laparoscopic radical resection of esophageal cancer in our hospital from January 2020 to December 2021.The study aimed to investigate the correlation between clinical pathological indicators and commonly used measurement indicators of sarcopenia and postoperative pneumonia.Statistical analysis was performed to analyze the data.Results:The study found that the proportion of postoperative pneumonia in esophageal squamous cell carcinoma patients aged 70 years and above was 27.9%(111 out of 398). The pneumonia group had significantly lower preoperative BMI and peak expiratory flow(PEF)measurements compared to the non-pneumonia group, with statistically significant differences( t=2.799, 2.674, both P<0.05). Logistic multivariate analysis revealed that low PEF, low psoas major muscle index(PMI), and low psoas muscle density(PMD)were the primary risk factors for postoperative pneumonia in esophageal cancer patients aged 70 years and above(Wald χ2 values were 7.577, 6.091, 6.845, all P<0.05). The risk of postoperative pneumonia in esophageal cancer patients aged 70 years and above with low PEF, low PMI, and low PMD was found to be 1.969 times higher(95% CI: 1.215-3.185, P=0.006), 1.912 times higher(95% CI: 1.143-3.205, P=0.014), and 1.832 times higher(95% CI: 1.164-2.882, P=0.009)respectively, compared to patients with high PEF, high PMI, and high PMD. Conclusions:Low PEF, low PMI, and low PMD are significant risk factors for postoperative pneumonia in esophageal cancer patients aged 70 years and older.Preoperative PEF, PMI, and PMD, which are commonly utilized measurement indicators for sarcopenia, can be utilized as early screening indicators for postoperative pneumonia.

AIM: To establish a method for quantitation of cefepime and avibactam in M-H broth, and applicated in the in vitro dynamic PK/PD model. METHODS: The cefepime was also determined using the high-performance liquid chromatography method (HPLC), the avibactam was also determined using the liquid chromatography-mass spectrometry (LC-MS/MS), an in vitro dynamic PK/PD model was established to study the PK/PD relationship of cefepime/avibactam against carbapenem resistant Klebsiella pneumoniae (CRKP). RESULTS: The linear ranges of cefepime and avibactam were good at (0.5-20) and (0.1-25) μg/mL (r=0.999), and the lower limit concentrations were 0.5 and 0.1 μg/mL. The extraction recoveries of cefepime and avibactam in M-H broth were 88.0%-101.7% and 90.9%-95.2%, the relative standard deviation of intra-day precision and inter-day precision were less than 5.2%. The concentration-time curves were well simulated by the PK/PD model. All observed concentrations in each experiment were in the range of 20% of the targeted values. For the CRKP of MIC=8 μg/mL and MIC=16 μg/mL, the colony decreased to 2.783Log10 CFU/mL and 1.325Log10 CFU/mL at the cefepime/avibactam 2.5 g q8 h administration after 24 h. CONCLUSION: The determination method of cefepime and avibactam in broth established in this study has high sensitivity and good stability. For the CRKP with MIC≤8 μg/mL,cefepime/avibactam showed that good anti-CRKP activity under routine administration in vitro dynamic PK/PD model.

To discuss the effect of varicella vaccination on the clinical characteristics of herpes zoster (shingles) cases aged 20 years and under, and analyze its clinical features. Based on the Yichang Health Big Data Platform, a descriptive study was conducted to collect the information of cases aged 20 years and under in three medical institutions of Yichang Central People's Hospital, Yichang First People's Hospital and Yichang Second People's Hospital from March 2019 to September 2020. According to the history of varicella vaccine, cases were divided into vaccination group and non-vaccination group, and their clinical features and outcomes were compared. The results showed that 46 shingles cases, aged from 7 to 20 years old, were included in this study. 26 males (56.5%), 20 females (43.5%), 15 cases in vaccination group (32.6%) and 31 cases in non-vaccination group (67.4%). 28 cases had thoracic involvement, followed by lumbar (n=8), cranial (n=7) involvements and extremities (n=7). The spread of herpes skin area: 2 cases involved too large area, 21 cases of 10 cm×10 cm, 14 cases of 5 cm×5 cm, 9 cases of 1 cm×1 cm. Herpes number: 26 cases had 10-49 herpes, followed by <10 herpes (n=9), uncountable herpes (n=7) and 50-99 herpes (n=4). The clinical course[M(Q₁,Q₃)] lasted 20.5 (13.5,24.8) d averagely, 5 cases had postherpetic neuralgia (PHN) and 1 case had respiratory complications. Shingles decrustation time was significantly shorter in vaccination group (Z=-2.01, P<0.05), and there was no significant difference in other characteristics by vaccination. In conclusion, the number and spread of shingles in most children and adolescents are less, and the complications such as PHN are less. Varicella vaccination can reduce the decrustation time and relieve shingles cases with some clinical symptoms.

OBJECTIVE: To retrospectively analyze the clinical characteristics and prognostic factors of patients with primary cutaneous lymphoma. METHODS: The clinical data of 22 patients with primary cutaneous lymphoma admitted to Xinjiang Hotan District People's Hospital, Heji Hospital affiliated to Changzhi Medical College and the Fifth Medical Center of PLA General Hospital from January 2013 to June 2021 were retrospectively analyzed. RESULTS: The incidence of primary cutaneous T cell and NK/T cell lymphoma was about 91.9/100 000, and the incidence of primary cutaneous B cell lymphoma was about 14.5/100 000. The overall survival (OS) of patients aged ≥65 years was significantly shorter than that of patients younger than 65 years (P <0.05). Patients with elevated β₂-microglobulin (β₂-MG) had shorter OS and progression-free survival (PFS) (both P <0.05). Patients who achieved complete/partial response after initial treatment had longer OS than those with stable or progressive disease (P <0.05). There were significant differences in OS and PFS among patients with different pathological types of primary cutaneous lymphoma that originated from T and NK/T cells, the OS and PFS of patients with mycosis fungoides were longer than those of patients with other pathological types (both P <0.05). In addition, disease stage might also affect the PFS of the patients (P =0.056). CONCLUSION The age, disease stage, β₂-MG level, pathological type and remission state after treatment of the patients were related to the clinical prognosis.

Objective:To investigate the effect of sarcopenia on the perioperative clinical outcomes of esophageal squamous cell carcinoma (ESCC).Methods:The retrospective case-control study was conducted. The clinicopathological data of 1 148 ESCC patients who were admitted to the Affiliated Huaian No.1 People′s Hospital of Nanjing Medical University from January 2020 to December 2021 were collected. There were 789 males and 359 females, aged (67±7)years. All patients under-went thoracoscopic and laparoscopic radical esophagectomy for esophageal cancer. Observation indicators: (1) incidence of sarcopenia in patients with ESCC; (2) comparison of general data between ESCC patients complicated with sarcopenia and those without sarcopenia; (3) comparison of clinical outcomes between ESCC patients complicated with sarcopenia and those without sarcopenia; (4) analysis of influencing factors for sarcopenia in ESCC patients. Measurement data of normal distri-bution were represented by Mean± SD, and comparison between groups was conducted using the t test. Count data were represented as absolute numbers, and comparison between groups was conducted using the chi-square test. Ordinal data was analyzed using the Mann-Whitney U test. Logistic regression analysis was used to conduct univariate analysis. Logistic backward stepwise regression model was used to conduct multivariate analysis. Results:(1) Incidence of sarcopenia in patients with ESCC. Among 1 148 ESCC patients, 469 cases were complicated with sarcopenia, 679 were without sarcopenia. The incidence of sarcopenia was 40.854%(469/1 148). Among the 469 patients with sarcopenia, there were 313 males and 156 females. There were 125 cases <65 years old, 145 cases ≥65 years old but <70 years old, 106 cases ≥70 years old but<75 years old, 93 cases ≥75 years old, respectively. (2) Comparison of general data between patients with ESCC complicated with sarco-penia and those without sarcopenia. The age, tumor diameter, body mass index, cases in stage T1, T2, T3, preoperative albumin, preoperative serum prealbumin, psoas muscle index, psoas muscle density were (68±7)years, (3.3±1.5)cm, (22.4±2.9)kg/m 2, 100, 105, 264, (43±4)g/L, (193±38)mg/dL, (3.9±0.8)cm 2/m 2, (48±8)HU of 469 ESCC patients complicated with sarcopenia, versus (66±7)years, (3.2±1.4)cm, (23.8±3.0)kg/m 2, 173, 170, 336, (44±4)g/L, (206±37)mg/dL, (6.0±2.2)cm 2/m 2, (50±7)HU of 679 ESCC patients without sarcopenia, showing significant differences between the two groups ( t=5.74, 2.11, 7.57, Z=-2.93, t=2.25, 5.52,20.36, 4.18, P<0.05). (3) Comparison of clinical outcomes between patients with ESCC complicated with sarcopenia and those without sarcopenia. The duration of postoperative hospital stay, cases with postoperative hospital stay>30 days, pneumonia, acute respiratory failure, anastomotic fistula, and abnormal heart rhythm were (17±9)days, 32, 158, 39, 33, and 103 of 469 ESCC patients complicated with sarcopenia, respectively, versus (15±6)days, 15, 102, 18, 19, and 85 of 679 ESCC patients without sarcopenia, showing significant differences between the two groups ( t=4.89, χ2=15.04, 55.17, 18.86, 11.52, 18.06, P<0.05). (4) Analysis of influencing factors for sarcopenia in ESCC patients. Results of multivariate analysis showed that age ≥65 years was an independent risk factor for sarcopenia in ESCC patients ( odds ratio=1.64, 95% confidence interval as 1.26-2.14, P<0.05). Preoperative serum prealbumin ≥200 mg/dL, psoas muscle density ≥48 HU and body mass index >24 kg/m 2 were independent protective factors for sarcopenia in ESCC patients ( odds ratio=0.64, 0.72, 0.53, 95% confidence interval as 0.50-0.82, 0.56-0.92, 0.41-0.69, P<0.05). Conclusions:Age ≥65 years is an independent risk factor for sarcopenia in ESCC patients. Preoperative serum prealbumin ≥200 mg/dL, psoas muscle density ≥48 HU and body mass index >24 kg/m 2 are independent protective factors for sarcopenia in ESCC patients. Compared with patients without sarcopenia, ESCC patients with sarcopenia are more prone to postoperative compli-cations such as pneumonia, acute respiratory failure, anastomotic fistula, and arrhythmia, and have a longer postoperative hospital stay.

This article reports a patient with extensive high-pressure injection injury of the hand caused by mistaken injection of polyurethane material into the index finger, who was diagnosed and treated in the Department of Orthopedics of Huzhou Central Hospital in 2019. Both the digital artery and digital nerve were involved, and the polyurethane involved the right palm along the flexor tendon sheath of the index finger and wrist. Due to the lack of X-ray development, the scope of the first debridement was small, and the blood supply to the fingertip was poor. Finally, the patient's right index finger was amputated due to infection and necrosis. MR or B-ultrasound should be perfected before operation to clarify the extent of polyurethane involvement. The initial thorough debridement or multiple debridements are necessary to improve the prognosis. If the blood supply of the fingers is poor, the blood supply can be reconstructed by skin flap transplantation.

Objective:To investigate the correlation of PELP1/MNAR expression with expressions of estrogen receptor (ER), Ki-67, human epidermal growth factor receptor 2 (HER2) and PIK3CA gene mutation.Methods:A total of 80 paraffin-embedded tissue specimens of primary invasive breast cancer patients in the Fifth People's Hospital of Datong in Shanxi Province from January 2008 to December 2018 were collected. The expression of PELP1/MNAR was examined by immunohistochemistry EliVision tow-step method. The polymerase chain reaction (PCR)-Sanger sequencing method was used to detect the mutation of PIK3CA gene. The expressions of PELP1/MNAR among patients with different expression status of ER, Ki-67, HER2 and with or without PIK3CA gene mutation were compared, and the correlations between each index and the expression of PELP1/MNAR were analyzed.Results:The high expression rates of PELP1/MNAR protein in patients with ER-positive [86.1% (31/36) vs. 59.1% (26/44)], Ki-67 high expression [100.0% (13/13) vs. 65.7% (44/67)], HER2-positive [81.0% (34/42) vs. 60.5% (23/38)] were high, and the differences were statistically significant (all P<0.05). There was no significant difference in the high expression rate of PELP1/MNAR protein between patients with mutant and wild-type PIK3CA [60.0% (12/20) vs. 75.0% (45/60), P = 0.199]. The expression of PELP1/MNAR was negatively correlated with the expression level of ER ( r = -0.195, P < 0.05), positively correlated with the expression level of Ki-67 ( r = 0.198, P < 0.05), positively correlated with the expression level of HER2 ( r = 0.225, P < 0.05), and negatively correlated with lymph node metastasis ( r = -0.269, P < 0.05). Conclusions:The expression of PELP1/MNAR in invasive breast cancer is negatively correlated with the expression level of ER, and positively correlated with the expression level of Ki-67 and HER2. There is no correlation between PELP1/MNAR expression and PIK3CA gene mutation, and the two may play their own role in the PI3K-AKT-mTOR regulatory pathway of breast cancer.

OBJECTIVE: To study the long-term clinical effect of multicenter multidisciplinary treatment (MDT) in children with renal malignant tumors. METHODS: A retrospective analysis was performed on the medical data of 55 children with renal malignant tumors who were diagnosed and treated with MDT in 3 hospitals in Hunan Province from January 2015 to January 2020, with GD-WT-2010 and CCCG-WT-2016 for treatment regimens. A Kaplan-Meier survival analysis was used to analyze the survival of the children. RESULTS: Of the 55 children, 10 had stage I tumor, 14 had stage Ⅱ tumor, 22 had stage Ⅲ tumor, 7 had stage IV tumor, and 2 had stage V tumor. As for pathological type, 47 had FH type and 8 had UFH type. All children underwent complete tumor resection. Of the 55 children, 14 (25%) received preoperative chemotherapy. All children, except 1 child with renal cell carcinoma, received postoperative chemotherapy. Among the 31 children with indication for radiotherapy, 21 (68%) received postoperative radiotherapy. One child died of postoperative metastasis. The incidence rate of FH-type myelosuppression was 94.4%, and the incidence rate of UFH-type myelosuppression was 100%. The median follow-up time was 21 months and the median survival time was 26 months for all children, with an overall survival rate of 98% and an event-free survival rate of 95%. CONCLUSIONS Multicenter MDT has the advantages of high success rate of operation and good therapeutic effect of chemotherapy in the treatment of children with renal malignant tumors, with myelosuppression as the most common side effects, and radiotherapy is safe and effective with few adverse events. Therefore, MDT has good feasibility, safety, and economy.

Objective To determine the prevalence rate of elevated fasting plasma glucose(FPG)in residents of Liaoning Province and to identify the risk factors, which will help to effectively prevent/alleviate the occurrence and development of diabetes for reduction of socioeconomic burden. Methods A multi-stage stratified random cluster sampling method was used to investigate the residents of 3 towns and 3 rural areas in Liaoning Province. A total of 53 497 adults(aged 35-75 years)were surveyed by questionnaires and the risk or protective factors were analyzed by logistic regression method. Results The prevalence rate of elevated FPG was 24.7% with 23.2% in males and 26.0% in females, respectively. The results of multivariate logistic regression showed that age increase, female, high education, occupation(except farmers), alcohol drinking, obesity, hypertension, and dyslipidemia were risk factors of FPG(P < 0.05 or P < 0.001). Conclusion The prevalence of elevated FPG is high in the study population aged 35-75 years in Liaoning. It is necessary to strengthen the intervention in this part of the population in order to reduce the incidence of diabetes mellitus.

OBJECTIVE: Quantitative assessment of white blood flow in semi-oval center of patients with delayed neuropathological sequelae (DNS) after carbon monoxide poisoning treated with acupuncture combined with hyperbaric oxygen (HBO) based on magnetic resonance multi-inversion time arterial spin labeling imaging (mTI-ASL), and to evaluate its efficacy indirectly. METHODS: Twenty-six patients with clinically diagnosed DNS were randomly divided into an observation group (13 cases) and a control group (13 cases). The conventional therapy combined with HBO were given in the control group. In the observation group,on the base of the treatment, acupuncture was applied, the main acupoints were Shuigou (GV 26), Neiguan (PC 6), Baihui (GV 20), Shangxing (GV 23), Yintang (GV 29), Sanyinjiao (SP 6) on the affected side, Sishencong (EX-HN 1), Fenglong (ST 40), Lianquan (CV 23) and Jinjin (EX-HN12) for slurred speech, Jianyu (LI 15), Waiguan (TE 5) and Shousanli (LI 10) for upper limb pain, Huantiao (GB 30), Yanglingquan (GB 34), Yinlingquan (SP 9) for lower limb pain, the treatment was given once every day, 5 days as one course, with an interval of 2 days between the course. The treatment for 6 courses was required. The conventional head MR scan, mTI-ASL and diffusion tensor imaging (DTI) scans before and 1 week after treatment were adopted, Matlab (R2014b), Mricron and Syngo.via software were adopted to measure the cerebral blood flow (CBF) and anisotropy (FA) values of the semi-oval center. The correlation between the parameters was evaluated by Pearson method. And the simple intelligent mental state examination scale (MMSE) was uesd to assess cognitive function. RESULTS: After treatment, the CBF, MMSE scores in both groups and FA values in the observation group were higher than those before treatment (<0.05). After treatment, the CBF, FA and MMSE scores in the observation group were significantly higher than those in the control group (<0.05). There was a positive correlation between CBF, FA and MMSE scores (<0.05), and the correlation between CBF and MMSE was the best ( =0.822). CONCLUSION Acupuncture combined with hyperbaric oxygen can significantly improved early white matter hypoperfusion and improved cognitive function score in patients with DNS. The curative effect is better than that of hyperbaric oxygen therapy alone. The mTI-ASL imaging can quantitatively evaluate its curative effect.
