Objective To observe the effect of cluster needling at scalp acupoints plus paraffin therapy on motor function in cerebral palsy patients.Method Forty eligible patients with spastic cerebral palsy were randomized into a control group and an experimental group, 20 cases in each group. The control group was intervened by cluster needling with long-time retaining of the needles plus Uyeda's approach and conventional rehabilitation trainings specifically for spastic cerebral palsy; the experimental group was intervened by paraffin therapy in addition to the treatment given to the control group. The interventions were conducted once a day, for a total of 8 weeks. The Gross Motor Function Measure-88 (GMFM-88) and Modified Ashworth Scale (MAS) were adopted to evaluate the motor function before and after the treatment.Result The GMFM-88 scores were significantly changed after the treatment in both groups (P<0.05), and there was a significant difference in comparing the GMFM-88 score between the two groups after the intervention (P<0.05). The MAS score was significantly changed after the intervention in the experimental group (P<0.05), while the score wasn't significantly changed in the control group (P>0.05); there was a significant difference in comparing the MAS score between the two groups after the intervention (P<0.05).Conclusion On the basis of conventional rehabilitation trainings, cluster needling at scalp acupoints plus paraffin therapy can produce a significant efficacy in improving the muscular tension and motor function, and benefit the development of cerebral palsy patients.

Objective Acne vulgaris remains a major problem in dermatological practice. Phototherapy for acne with blue and red light-emitting diode (LED) arrays has recently attracted attention.The aim of this study is to observe the clinical effect of the blue and red light combination phototherapy on acne. Methods 65 individuals were recruited: 25 females and 5 males. Patients underwent treatment of 20-25 minutes blue light and 5-10 minutes combined light treatment twice per week. Continuous irradiation for 4 weeks was as 1 session. Mild acne vulgaris was treated for 1 session, moderate and severe acne were treated for 1 or 2 sessions. Results After system treatment, the acne lesion was reduced apparently without side effect. The effective rate of mild acne vulgaris, moderate acne vulgaris and severe acne vulgris was 80 %, 89.4 % and 88.2 %, respectively. Conclusion The combination of blue and red light-emitting diode therapy for acne vulgaris is effective. This therapy is convenient without side effect, and it is a new preferable modality for the treatment of acne.

Objective To assess the efficacy and safety of 800 nm diode laser for removing unwanted hair of Ⅲ-Ⅴ skin type.Methods A total of 114 patients were treated with 800 nm diode laser on 234 sites.Four sessions were performed at an interval of 6-8 weeks.Percentage of hair reduction was evaluated 3 months after each session by comparing the terminal hair count to the baseline values.Follow-up was performed 6-8 months after the last session.In addition,subjective satisfaction of physicians and patients was evaluated according to a four-grade scale and the satisfaction rates were calculated.Results After fouth session,97.01％ of patients had more than 40 ％ hair reduction,and 83.33 ％ patients had more than 60 ％ hair reduction.Hyperpigmentation was observed on 15 (6.41％) sites,and disappeared after 6-8 months follow-up.The satisfactory rates of the physicians and the patients were 98.25 ％ and 96.12 ％,respectively,with no statistical difference (x2 =3.33,P＞0.05).Conclusions 800 nm diode laser for removing unwanted hair of Ⅲ-Ⅴ skin type is a safe and effective treatment option for hair removal,with relatively less side effect.

Objective To evaluate the effects of hyperbaric oxygen on the expressions of hypoxia-inducible factor 1α (HIF-1α) and insulin-like growth factor-1 receptor (IGF-1R) in the formation of hyperplastic scar in rabbit ears.Methods The ears of 20 New Zealand rabbits were used to construct an animal model for hyperplastic scar by operation.After the establishment of scar models,the rabbits were randomly divided into 4 experimental groups and one control group with 4 mice (48 wound surfaces) in each group.The mice in the 4 experimental groups were treated with hyperbaric oxygen for 7,14,21 and 28 days,respectively,and those in the control group remained in normoxic environment after operation.Scar tissues were resected from all the rabbit ears on day 29 after operation.Hematoxylin and eosin (HE) staining was conducted for the observation of morphological changes and calculation of scar elevation index,and immunohistochemistry to measure the expressions of HIF-1α and IGF-1R.Statistical analysis was carried out by one-way analysis of variance followed by least significant difference t-test.Results HE staining showed that both the number of fibroblasts and amount of collagen fibers were significantly reduced in the experimental groups compared with the control group.Scar elevation index was 4.28 ± 0.22 in the control group,3.64 ± 0.29,3.46 ± 0.21,3.29 ± 0.21,3.16 ± 0.15 in the 7-,14-,21-and 28-day experimental groups respectively,with significant differences among these groups (F =77.70,P ＜ 0.05).The expressions of HIF-1α and IGF-1R were significantly lower in these experimental groups than in the control group (all P ＜ 0.01),lower in the 14-day group than in the 7-day group (P ＜ 0.05),and lower in the 21-day group than in the 14-day group (P ＜ 0.05),with no significant differences between the 28-day group and 21-day group (both P ＞ 0.05).Conclusion Hyperbaric oxygen can effectively down-regulate the expressions of HIF-1α and IGF-1R in scar tissue,and significantly inhibit the formation of hyperplastic scar in rabbit ears.

Objective:To explore the clinicopathologic features and diagnostic criteria of hepatosplenic T-cell lymphoma (HSTCL). Methods: Three cases of HSTCL were seached for morphology, immunophenotypings, Epstein-Barr virus (EBV) in situ hybridization and T-cell receptor? (TCR?) gene rearrangement. Results: In the bone marrow, the infiltrative pattern of tumour cells was interstitial and sinusoidal infiltration in one case,while the other two cases showed diffuse infiltration. In the liver of one case and the spleen of another case, tumour cells respectively showed sinusoidal infiltration. The immunophenotyping: three cases showed strongly positive for CD3 and TIA-1, but negative for Granzyme B, CD56 and TCR?. EBV in situ hybridization was not detected in all the cases. TCR? monoclonal rearrangements were detected in two cases. Conclusion: HSTCL is a rare entity which is classified into peripheral T cell lymphomas. And it is regarded as a subset of unactived cytotoxic T-cell lymphomas. The negative results of EBV in situ hybridization and the presentation of TCR? gene monoclonal rearrangements may be helpful in diagnosis and differential diagnosis of HSTCL. These three cases showed similar characters to those of international cases reported.

Objective:To evaluate angioimmunoblastic T-cell lymphoma(AITL) completely, we gave in-depth investigation of histopathological features, specific immunochemical markers, antigen receptor gene rearrangements and in situ hybridization for Epstein-Barr virus (EBV). Methods: 15 cases of typical AITL displayed effacement of the normal lymph node architecture partially or completely, abundance of arborizing high endothelial vessels, infiltration of polymorphic cells and hyperplastic atypical T lymphocytes with or without clear cytoplasm. Clinical characteristics, histological manifestations, and immunohistochemical staining for CD3, CD20, CD4,CD21, CXCL13, CD10, and BCL6 were analyzed. Polymerase chain reaction for immunoglobulin heavy chain (IgH) and T cell receptor ? (TCR?) rearrangements and in situ hybridization for Epstein-Barr virus encoded RNA (EBER-1) were performed.Results: Histologically, we found eight cases with regressed lymphoid follicles, six with absence of follicles and one with hyperplastic follicles with interfollicular lesions. We also found eight cases displaying aggregation of clear cells, four infiltration of large lymphoid cells, five abundant epithelioid histiocytes. CD20 staining showed hyperplasia of large B cells in four cases. CD21 expression exihibited extrafollicular expansion of follicular dendritic cell meshworks in 11 cases (73.3%), partially with a tendency of perivascular distribution. Positive rate for CXCL13 and CD10 are 73.3% and 6.7% respectively. Monoclonal rearrangements of TCR? were detected in 6/15 (40%) of cases, IgH rearrangements in 7/15 (46.7%), of which five were monoclonal, while two oligoclonal. 8 out of 15 cases (53.3%) contained EBV-positive cells. Among the four cases with large B cell proliferation, three were EBV-positive. Conclusion: AITL display great complexity and diversity clinicopathologically. Only when we recognize such diversity, can we reasonably apply and properly evaluate immunochemical markers and molecular techniques, and thus give a correct diagnosis.

Abstract: Objective To investigate the impact of SARS-CoV-2 virus infection on the risk of thrombosis in COVID-19 outpatient patients with mild and regular symptoms. Methods Outpatient patients during the SARS-CoV-2 large-scale infection period after the policy adjustment for COVID-19 in Beijing in 2022 were selected as the observation group, and the dynamic zero-clearing period before the policy adjustment and outpatient patients during the 2022/2021/2020 period were taken as the three control groups. The patients with physiological factors that may increase the risk of coagulation, such as thrombotic diseases, malignant tumors, female pregnancy and other physiological factors, were excluded. Pediatric patients under 14 years old were also excluded. Age was expressed as median (interquartile). The changes in blood routine, fibrin/fibrinogen degradation products, and D-Dimer in Beijing outpatient patients were studied with statistical method and data analysis techniques. Results Compared with the control groups, the observation group showed a statistically significant decrease in red blood cells (RBC), hemoglobin (Hb), and hematocrit (HCT) levels, and an increase in monocytes (MONO) and platelet (PLT) counts, all showed statistically significant differences (P<0.0001). The proportion of fibrinogen degradation product (FDP) and D-Dimer of observation group exceeding the range increased significantly. Compared with the three control groups, the number of outpatient fibrinogen degradation products (FDP) in the observation group of patients aged 50 years and verage number of patients under 50 years old in the observation group with D-Dimer exceeding the threshold increased by more than 48.98%, and the monthly average number of patients with D-Dimer exceeding the threshold in patients aged 50 or older increased by 346%-998%. Conclusions The results of this study suggest that outpatient patients with mild or regular SARS-CoV-2 infection are also at risk for thrombotic events, and monitoring blood coagulation indicators such as D-dimer is recommended to avoid the sudden onset of thrombosis-related fatal complications .

Background T helper cell 17 (Th17),a newly discovered subset of CD4+ T cells,have been found to play an important role in dry eye disease in animal model.Further investigation should be done on the immunopathogenesis of Th17 cells in dry eye patients.Objective This study was to analyze the expression status of interleukin-17 (IL-17) and IL-22 in tear and supernatant of peripheral blood mononuclear cells (PBMCs) of dry eye patients and their correlation with clinical symptom and sign.Methods Twenty Sj(o)gren syndrome (SS)patients,twenty non-Sj(o)gren syndrome (NSS) patients were included in Wuxi Second Hospital from 2010 to 2011,and twenty healthy volunteers were recruited at the same period.All of subjects understood the purpose and procedure of research and written informed consent was obtained form each subject initial of this study.Dry eye symptom questionnairs were self-answered and multiple dry eye disease-related clinical tests,including the breakup time of tear film (BUT),Schirmer Ⅰ test (S Ⅰ t) and corneal fluorescein staining were performed.The periphery blood of 3 ml and tear were collected in all the subjects,and IL-17 and IL-22 levels in supernatant of PBMCs and tear were detected by enzyme-linked immunosorbent assay (ELISA).The correlations between levels of IL-17 and IL-22 with BUT,S Ⅰ t,corneal fluorescein staining and dry eye scores were analyzed.Results The dry eye scores reduced,BUT prolonged,S Ⅰ t increased and corneal fluorescein dye decreased from SS group,NSS group to normal control group,with significant differences among the three groups (dry eye scores:H =40.81,P＜0.01 ; BUT:H =40.15,P＜0.01 ;S Ⅰ t..H=50.07,P＜0.01 ;corneal dye scores:H=40.52,P＜0.01).The concentration of IL-17 in the supernatant of PBMCs in the SS patients,NSS patients and normal controls were (964.92±124.83)ng/L,(718.85± 115.89)ng/L and (341.95±85.08) ng/L,showing a statistically significant difference among them (F=162.95,P＜0.01).The levels of IL-17 in the tear were (440.69±126.09) ng/L,(364.33±126.85) ng/L and (61.16±11.60) ng/L in the SS group,NSS group and normal control group respectively,exhibiting an elevated level in the SS group and NSS group compared with the control group (F=75.27,P＜0.01).In addition,the levels of IL-22 in the supernatant of PBMCs in the SS patients,NSS patients and normal controls were (98.77± 11.27) ng/L,(79.65 ± 11.01) ng/L and (32.78±9.34) ng/L,and those in the tear were (22.22 ± 8.96) ng/L,(14.92 ±4.35) ng/L and (10.47 ± 2.67) ng/L,with significant differences among the three groups (F =206.27,P＜0.01 ;F =19.87,P＜0.01).The significant correlations were found between the IL-17 and IL-22 concentration in the supernatant of PBMCs and tear with corneal fluorescein staining scores and S Ⅰ t.Conclusions The contents of IL-17 and IL-22 in PBMCs and tear upregulate in the SS and NSS patients,indicating that Th17 plays a key role in the immunity mechanism of dry eye.

Abstract: AIDS combined with Pneumocystis jirovecii pneumonia (PJP) and disseminated infections of Talaromyces marneffei and Cryptococcus neoformans are rare. This paper summarizes and analyzes the diagnosis and treatment of an AIDS patient with multiple fungal infections for reference. A 79-year-old male patient was admitted to the hospital with "stool habit change for more than 20 days". The white blood cell count was 4.57×109/L, the percentage of neutrophils was 81.8%, the absolute count of CD4+ lymphocytes was 6/μL, and the CD4/CD8 ratio was 0.17. HIV antibody positive was confirmed by CDC. The cerebrospinal fluid and alveolar lavage fluid were positive for Cryptococcus neoformans capsular antigen, and Pneumocystis jirovecii was found by the bronchoalveolar lavage fluid stained with hexamine silver. The cerebrospinal fluid culture was positive for Cryptococcus neoformans, and the blood culture was positive for Cryptococcus neoformans and Talaromyces marneffei. CT showed that bronchovascular bundles in both lungs were more thick, patchy and cable-like high-density shadows were seen in both lungs, and the edges were blurred. Nodular and cable-like high-density shadows were seen in the posterior apical segment of the left upper lobe, with clear margins. Infection of both lungs was considered, and secondary pulmonary tuberculosis occurred in the left upper lobe. After admission, the patient was treated with various anti-bacterial and fungal drugs due to recurrent fever, but the effect was not effective. The fever symptoms of the patient could not be significantly improved, and his condition continued to worsen, and he eventually died. The patient with AIDS complicated with bacterial and fungal infection, especially PJP infection in serious condifiton and has a poor prognosis for rapid development, so clinical attention should be paid to.
