Objective To evaluate the safety and efficacy of single and local use of a China-made compound betamethasone injection in the treatment of lichen simplex chronicus. Methods A multi-center,randomized, parallel controlled study was conducted. Patients with lichen simplex chronicus were divided into test and control groups to receive a single dose of intralesional compound betamethasone injection made in China or Schering-Plough Labo N.V. Belgium. Patients were visited for the evaluation of efficacy and safety of the China-made injection at the beginning of the treatment (DO), on week 2 (D14) and 4 (D28) after the initiation of treatment. Results A total of 144 patients were enrolled, among which, 68 in the control group and 71 in the test group completed the trial. FAS analysis on week 4 revealed that the response rate and healing rate were 86.11% and 59.72% in the control group, respectively, 86.11% and 54.17% in the test group, respectively (χ2=0.00,0.45,respectively,both P>0.05).There was no severe adverse event in either group after the treatment, and only mild atrophoderma occurred in one patient in the control group, which was improved spontaneously within several weeks of follow-up. There was no statistically significant difference in the occurrence of side reactions between the two groups (P> 0.05). Conclusion The China-made compound betamethasone injection is effective and safe for the treatment of lichen simplex chronicus.

Background:
Dysimmunity plays a key role in diabetes, especially type 1 diabetes mellitus. Islet-specific autoantibodies (ISAs) have been used as diagnostic markers for different phenotypic classifications of diabetes. This study was aimed to explore the relationships between ISA titers and the clinical characteristics of diabetic patients.
Methods:
A total of 509 diabetic patients admitted to Department of Endocrinology and Metabolism at the Affiliated Hospital of Nantong University were recruited. Anthropometric parameters, serum biochemical index, glycosylated hemoglobin, urinary microalbumin/creatinine ratio, ISAs, fat mass, and islet β-cell function were measured. Multiple linear regression analysis was performed to identify relationships between ISA titers and clinical characteristics.
Results:
Compared with autoantibody negative group, blood pressure, weight, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), visceral fat mass, fasting C-peptide (FCP), 120 minutes C-peptide (120minCP) and area under C-peptide curve (AUCCP) of patients in either autoantibody positive or glutamate decarboxylase antibody (GADA) positive group were lower.Body mass index (BMI), waist circumference, triglycerides (TGs), body fat mass of patients in either autoantibody positive group were lower than autoantibody negative group. GADA titer negatively correlated with TC, LDL-C, FCP, 120minCP, and AUCCP.The islet cell antibody and insulin autoantibody titers both negatively correlated with body weight, BMI, TC, TG, and LDL-C. After adjusting confounders, multiple linear regression analysis showed that LDL-C and FCP negatively correlated with GADA titer.
Conclusion
Diabetic patients with a high ISA titer, especially GADA titer, have worse islet β-cell function, but less abdominal obesity and fewer features of the metabolic syndrome.

OBJECTIVETo investigate the quantities of monocyte-derived dendritic cell precursors (pDC1) and plasmacytoid dendritic cell precursors (pDC2) in peripheral blood mononuclear cells (PBMC) of severe aplastic anemia (SAA) patients before and after immune suppressive therapy (IST), the ratio of the pDC1 to pDC2, and the expression of co-stimulating molecules (CD80, CD86, CD40) on dendritic cells (DC) and B cells in SAA patients.
METHODSBy means of three color monoclonal antibody labeling technology, the quantities and ratio of pDC1 and pDC2 in PBMC were detected in 26 SAA patients at active phase, 13 at recovery phase and 15 normal controls respectively. The aforementioned parameters of 10 SAA patients were tested before and 2 months after IST. The expression of CD80, CD86 and CD40 on DC and B lymphocytes were detected in 16 SAA patients and 15 normal controls.
RESULTSThe percentages of pDC1 and the ratio of pDC1/pDC2 of controls were (0.41 +/- 0.05)% and 1.58 +/- 0.18 respectively, and those of SAA patients at active phase were (0.67 +/- 0.13)% and 2.70 +/- 0.32 respectively, [pDC1 (P < 0.05); pDC1/ pDC2 ratio (P < 0.01)]. The aforementioned parameters in convalescent SAA patients decreased to (0.43 +/- 0.10)%, and 1.78 +/- 0.36 respectively, being no difference from those of normal controls. The percentages of pDC1 and pDC2 in 10 SAA patients were (0.87 +/- 0.31)%, and (0.35 +/- 0.09)%, before IST, and (0.24 +/- 0.09)%, (0.14 +/- 0.04)%, after IST, being significantly decreased (P < 0.05). The percentages of CD86 expression on DC of controls was (11.97 +/- 4.31)%, and that of SAA patients was (29.84 +/- 3.02) % (P < 0.05). The percentages of CD80, CD40 and CD86 expression on lymphocytes of controls were (2.57 +/- 0.44)%, (7.34 +/- 1.22)% and (1.86 +/- 1.11)%, respectively, and those of SAA patients were (5.17 +/- 0.68)%, (8.85 +/- 2.94)% and (5.98 +/- 0.96)% respectively (P < 0.05, P < 0.01). The percentage of CD86 expression on B lymphocytes in controls was 8.04 +/- 0.66%, and in SAA patients was (20.46 +/- 2.78)%, (P < 0.05).
CONCLUSIONThe pDC subtypes were abnormal and the percentage of pDC1 is increased in SAA patients, which are associated with stage of this disease. DC and B Lymphocytes in SAA patients upregulated expression of costimulatory molecules (CD86) which cause the T lymphocyte abnormally activated.

Photodynamic action, due to the rather limited lifetime (1 μs) and effective reactive distance of singlet oxygen (< 10 nm), could subcellular-specifically regulate different cellular functions. Photodynamic action could activate permanently cholecystokinin (CCK) 1 receptors, and sensitize or desensitize other G protein-coupled receptors. The emergence in recent years of genetically- encoded protein photosensitisers has enabled more precisely-targeted photodynamic modulation of subcellular organelles and functional proteins. Protein photosensitisers (such as KillerRed, miniSOG or SOPP) expressed on the plasma membrane, mitochondria, lysosomes or endoplasmic reticulum can modulate photodynamically subcellular functions and fine-tune protein activity by targeted photooxidation. With the newly emerged active illumination technique, simultaneous photodynamic action localized at multiple sites is now possible, and the contribution of subcellular regions to the whole cell or individual cells to a cell cluster could be quantitated. Photodynamic action with protein photosensitiser will be a powerful tool for nano-manipulation in cell physiology research.

Objective:To investigate the short-term clinical efficacy of Kamikawa anasto-mosis and jejunal interposed double channel anastomosis in laparoscopic proximal gastrectomy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 68 patients with esophagogastric junctional tumors and upper gastric tumors who underwent laparoscopic proximal gastrectomy in two medical centers, including 63 cases in the Changzhi People's Hospital Affiliated to Changzhi Medical College and 5 cases in the Heji Hospital Affiliated to Changzhi Medical College, from March 2018 to December 2020 were collected. There were 57 males and 11 females, aged 62(range, 39?78)years. Of 68 patients, 35 patients undergoing Kamikawa anastomosis in laparoscopic proximal gastrectomy were allocated into Kamikawa group, and 33 patients under-going jejunal interposed double channel anastomosis in laparoscopic proximal gastrectomy were allocated into double channel group. Observation indicators: (1) intraoperative situations; (2) post-operative situations; (3) follow-up. The patients were followed up by outpatient examinations and telephone interview to detect the postoperative score of chew-wun wu special symptoms, post-operative reflux anastomotic esophagitis and anastomotic stenosis up to December 2021. Measure-ment data with normal distri-bution were represented as Mean±SD, and comparison between groups was performed by the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted by Mann-Whitney U test. Comparison of ordinal data was performed by nonparametric rank sum test. Count data were expressed as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability method. Results:(1) Intraoperative situations. All the 68 patients successfully under-went laparoscopic proximal gastrectomy combined with D 1+ lymph node dissection. The operation time and volume of intraoperative blood loss of the Kamikawa group were (5.15±0.31)hours and (89±11)mL, versus (4.21±0.11)hours and (142±20)mL of the double channel group, respectively, showing significant differences between the two groups ( t=2.81, ?2.34, P<0.05). The digestive tract reconstruction time and the number of lymph node dissection were (1.95±0.13)hours and 30.4±2.4 of the Kamikawa group, versus (1.69±0.76)hours and 28.0±2.4 of the double channel group, respectively, showing no significant difference between the two groups ( t=1.79, 0.73, P>0.05). (2) Postoperative situations. The time to postoperative first flatus, duration of drainage tube placement, duration of postoperative hospital stay were (3.03±0.12)days, (5.46±0.22)days, (13.00±0.50)days of the Kamikawa group, versus (4.42±0.21)days, (9.97±0.76)days, (16.46±0.92)days of the double channel group, showing significant differences in the above indicators between the two groups ( t=?5.80,?5.58, 3.40, P<0.05). Cases with or without drainage tube placement were 32 and 3 of the Kamikawa group, versus 33 and 0 of the double channel group, respectively, showing no significant difference between the two groups ( P>0.05). Cases with grade 1, grade 2, grade 3, grade 4 complica-tions of Clavien-Dindo classification were 31, 0, 4, 0 of the Kamikawa group, versus 27, 3, 1, 2 of the double channel group, respectively, showing a significant difference between the two groups ( Z=?6.28, P<0.05). Postoperative anastomotic stenous, reflux symptoms, anastomotic fistula, pancreatic fistula, pulmonary infection were found in 4, 2, 0, 0, 0 case of the Kamikawa group and 0, 1, 3, 1, 2 cases of the double channel group, respectively. There was no significant difference in the above indicators between the two groups ( P>0.05). There was no complication of incisional infection, abdominal hemorrhage, lymphatic fistula or gastroparesis in either group. Of the 4 patients with perioperative anastomotic stenosis in the Kamikawa group, 2 cases were improved after once gastroscopic balloon dilatation, 2 cases were improved after 4 times of gastro-scopic balloon dilatation. (3) Follow-up. All the 68 patients were followed up at postoperative 3, 6, 12 months. The scores of chew-wun wu special symptoms scale at postopertaive 12 months of the Kamikawa group and double channel group were 16.8±0.7 and 14.6±0.7, respectively, showing a significant difference between the two groups ( t=2.20, P<0.05). There were 2 cases of grade B reflux esophagitis and 1 case of grade B reflux esophagitis, respectively, showing no significant difference between the two groups ( P>0.05). There was no anastomotic stenosis occurred in either group. Conclusions:Laparos-copic proximal gastrectomy with Kamikawa anastomosis or jejunal interposed double channel anastomosis is safe and feasible for esophagogastric junction tumors and upper gastric tumors. The Kamikawa anastomosis has less volume of intraoperative blood loss, shorter time to postoperative first flatus, duration of drainage tube placement and postoperative hospital stay, higher quality of postoperative lfe.

Objective:To investigate the influencing factors and regularity of inferior mediastinal lymph node metastasis in Siewert type Ⅱ and Ⅲ adenocarcinoma of esophagogastric junction (AEG).Methods:The retrospective case-control study was conducted. The clinicopatho-logical data of 185 Siewert type Ⅱ and Ⅲ AEG patients in two medical centers (113 cases in Changzhi People's Hospital Affiliated to Changzhi Medical College and 72 cases in Heji Hospital Affiliated to Changzhi Medical College) from January 2017 to January 2022 were collected. There were 143 males and 42 females, aged (64±8)years. Patients underwent radical resection of AEG combined with inferior mediastinal lymph node dissection. Observation indicators: (1) clinicopathological charac-teristics of Siewert type Ⅱ and Ⅲ AEG patients; (2) analysis of influencing factors for inferior mediastinal lymph node metastasis in Siewert type Ⅱ and Ⅲ AEG; (3) regularity of inferior mediastinal lymph node metastasis in Siewert type Ⅱ and Ⅲ AEG. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were represented as absolute numbers or percentages, and comparsion between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the rank sum test. Univariate and multivariate analyses were conducted using the Logistic regression model. Results:(1) Clinicopathological characteristics of Siewert type Ⅱ and Ⅲ AEG patients. Pathologic staging as stage Ⅰ, Ⅱ, Ⅲ and Ⅳ, degree of tumor invasion as stage T1, T2, T3 and T4, length of esophageal invasion ≤1 cm, >1 cm and ≤2 cm, >2 cm and ≤3 cm, >3 cm and ≤4 cm were found in 30, 61, 75, 7, 3, 41, 79, 50, 101, 46, 18, 8 cases of the Siewert type Ⅱ and Ⅲ AEG patients without inferior mediastinal lymph node metastasis, respectively, versus 0, 2, 10, 0, 0, 0, 5, 7, 4, 3, 2, 3 cases of the Siewert type Ⅱ and Ⅲ AEG patients with inferior mediastinal lymph node metastasis, showing a significant differences between them ( Z=?2.21, ?2.49, ?2.22, P<0.05). (2) Analysis of influencing factors for inferior mediastinal lymph node metastasis in Siewert type Ⅱ and Ⅲ AEG. Results of univariate analysis showed that pathological staging, depth of tumor invasion and length of esophageal invasion were related factors affecting inferior mediastinal lymph node metastasis in Siewert type Ⅱ and Ⅲ AEG ( odds ratio=2.48, 3.26, 2.03, 95% confidence intervals as 1.02?6.01, 1.21?8.80, 1.18?3.51, P<0.05). Results of multivariate analysis showed that depth of tumor invasion and length of esophageal invasion were independent influening factors affecting inferior mediastinal lymph node metastasis in Siewert type Ⅱ and Ⅲ AEG ( odds ratio=4.01, 2.26, 95% confidence interval as 1.35?11.96, 1.26?4.06, P<0.05). The inferior mediastinal lymph node metastasis probability of AEG patients with the length of esophageal invasion >3 cm and ≤4 cm was 9.47 times that of AEG patients with the length of esophageal invasion ≤1 cm. (3) Regularity of inferior mediastinal lymph node metastasis in Siewert type Ⅱ and Ⅲ AEG. The number of inferior mediastinal lymph nodes including No.110, No.111 and No.112 dissected in 185 patients of Siewert type Ⅱ and Ⅲ AEG were 127, 50 and 27. The number of lymph nodes dissected and the number of metastatic lymph nodes in No.110 and No.111 of patients with length of esophageal invasion ≤1 cm, >1 cm and ≤2 cm, >2 cm and ≤3 cm, >3 cm and ≤4 cm were 69, 4, 42, 4, 4, 1, 12, 4 and 23, 0, 17, 0, 7, 2, 3, 0, respectively. There were significant differences in metastatic lymph nodes in No.110 and No.111 of patients with length of esophageal invasion ≤1 cm, >1 cm and ≤2 cm, >2 cm and ≤3 cm, >3 cm and ≤4 cm ( χ2=8.45, 7.30, P<0.05). Of the 185 patients of Siewert type Ⅱ and Ⅲ AEG, the ratio of cases with inferior mediastinal lymph nodes metastasis was 6.49%(12/185). The ratio of inferior mediastinal lymph nodes metastasis in cases with length of esophageal invasion ≤1 cm, >1 cm and ≤2 cm, >2 cm and ≤3 cm, >3 cm and ≤4 cm were 3.81%(4/105), 6.12%(3/49), 10.00%(2/20), 27.27%(3/11), respectively. The ratio of No.110 lymph nodes metastasis in cases with length of esophageal invasion ≤1 cm, >1 cm and ≤2 cm, >2 cm and ≤3 cm, >3 cm and ≤4 cm were 2.86%(3/105), 6.12%(3/49), 5.00%(1/20), 27.27%(3/11), respectively, showing a significant difference among them ( χ2=8.26, P<0.05). Conclusions:Depth of tumor invasion and length of esophageal invasion are independent influening factors affecting inferior mediastinal lymph node metastasis in Siewert type Ⅱ and Ⅲ AEG. The rate of inferior mediastinal lymph node metastasis increases with the increase of the length of esophageal invasion.

OBJECTIVETo study the apoptosis and proliferation of CD(34) positive (CD(34)(+)) bone marrow cells (BMC) in patients with polycythemia vera (PV).
METHODSThe expression of Annexin V and Ki67 of the CD(34)(+) BMC in 20 PV patients and control cases [10 essential thrombocythemia (ET), 12 normal persons] were assessed by bicolor flow cytometry (FCM), and the correlation between apoptosis and clinical situation was analysed in PV patients.
RESULTSThe Annexin V expressions of CD(34)(+) BMC were (15.96 +/- 1.45)% in PV patients and (15.53 +/- 1.76)% in ET patients which were lower than that in normal subjects [(23.61 +/- 3.89)%, (P < 0.05)]. The Ki67 expression of CD(34)(+) BMC was (48.79 +/- 11.68)% in PV patients and (49.60 +/- 9.98)% in ET patients, which were significantly higher than that in normal controls (33.87 +/- 6.82)%. The ratio of apoptosis/proliferation in PV patients was 0.33 +/- 0.10 and in ET patients 0.32 +/- 0.02 which were significantly lower than that in normal controls 0.72 +/- 0.11 (P < 0.01). The apoptosis of CD(34)(+) BMC was negatively correlated with the hemoglobin (Hb) levels (r = -0.481, P = 0.037), white blood cells (WBC) (r = -0.538, P = 0.026) and the numbers of endogenous erythroid colony (EEC) (r = -0.632, P = 0.50), and the ratio of apoptosis/proliferation was negatively correlated with the Hb (r = -0.537, P = 0.018) and WBC (r = -0.667, P = 0.003) in PV patients.
CONCLUSIONThere were lower apoptosis and higher proliferation in CD(34)(+) BMC of PV patients. Lower apoptosis was correlated with the severity of the disease.
