Crataegus oxyacantha (Aubepine, Hawthorn), was used by european herbalist in the first century A. D. It went out fashion as a medicine until the 19th century for heart disease. The leaves, flowers, and berries of hawthorn contain a variety of bioflavonoid-like complexes that appear to be primarily responsible for the cardiac actions of the plant. Bioflavonoids found in C. oxyacantha include oligomeric procyanidins (OPCc), vitexin, quercetin, and hyperoside. The action of these compounds on the cardiovascular system has led to the development of leaf and flower extracts. As described in French pharmacopea, the hyperoside is the marker for quality control.

Objective: To study the in vitro antiproliferative effect and probable mechanism of solasonine on human breast cancer Bcap-37 cells, meanwhile, make comparison with solamargine. Methods: The cytotoxicity was evaluated by MTT assay. The cell damage and type of cell death were examined through Hoechst33342/PI and Annexin V/PI staining, respectively. Mitochondrial membrane potential was detected by JC-1 staining. The expression of Bcl-2, Bcl-xL, Bax, and cytochrome c was determined by immunoblot method, and the activation of caspase-3 was analyzed by immunocytochemistry method. Results: Solasonine showed the different extents of cytotoxicity on eight human tumor cell lines as well as four human normal cell lines, and the IC50 values of solasonine ranged from 12.73 to 37.15 μmol/L. Cell apoptosis and mitochondria depolarization were observed in Bcap-37 cells after treatment with solasonine for 24 h, respectively. In immunoblot and immunocytochemistry analysis, solasonine obviously induced the up-regulation of Bax and down-regulation of Bcl-2 and Bcl-xL, caused the release of cytochrome c from mitochondria into cytosol, and increased the expression of both pro- and cleaved caspase-3. Solamargine exhibited stronger antipoliferative activity than solasonine, but the similar mechanism in Bcap-37 cells in this study. Conclusion: Solasonine possesses the antiproliferative effect on tumor cells. Regulation of the levels of Bcl-2, Bcl-xL, Bax, and activation of mitochondria cytochrome c-dependent apoptosis pathway might be one of its main antitumor mechanisms against breast cancer cells. In view of the cytotoxic effect of solasonine and solamargine also shown on normal cells, the safety needs concern when the antitumor activity is studied.

Objective To clarify the advantages and disadvantages of domestic precision radiotherapy equipment by comparing the clinical efficacies of domestic and imported precision radiotherapy equipments in the treatment of lymphoma. Methods We investigated the treatments of lymphoma in hospitals of different levels using domestic and imported medical linear accelerators and divided them into domestic and imported groups. The data of patients in the two groups were retrospectively analyzed, and the radiotherapy equipment brand, short-term efficacy, acute toxicity, dosimetric parameters of organs at risk and the costs of radiation therapy were compared between the two groups. Results A total of 101 cases receiving radiation therapy for lymphoma in 10 hospitals were collected, including 77 cases in the imported group and 24 cases in the domestic group. The overall response rates were high in both groups, being 88.3% (68/77) in the imported group and 87.5% (21/24) in the domestic group, with no significant difference (P=1.00). The incidences of hematological toxicity (>grade 2) were low in both groups, being 1.3% (1/77) vs 8.3% (2/24), with no significant difference (P=0.14). Subgroup analysis was performed on the dosimetric parameters of organs at risk and acute toxicity of the two groups for extranodal nasal type NK/T cell lymphoma, and there were no significant differences in the maximal dose (Dmax) of the lens, Dmaxof the optic nerve, or mean dose (Dmean) of the parotid gland between the two groups (all P>0.05). However, there was an increasing trend in the domestic group compared with the imported group for Dmeanof bilateral parotid gland (left: [2 306.53±1 119.66] cGy vs[ 1 279.44±1 026.95] cGy, P=0.16; right:[ 2 328.35±1 009.76] cGy vs[ 1 303.79±1 116.79] cGy, P=0.17). The incidence of grade 2 xerostomia in the domestic group was higher than that in the imported group, but the difference was not statistically significant (50.0%[ 2/4] vs 14.3%[ 1/7], P>0.05). The domestic group had significantly lower radiotherapy cost [( 26 743.9±8 061.2] yuan vs[ 42 428.7±14 744.7] yuan) and total hospitalization cost [( 36 702.1± 12 225.8] yuan vs[ 50 192.7±15 494.4] yuan) than the imported group (both P<0.01). Conclusion There is no significant difference in the short-term efficacy of lymphoma treatment between the domestic radiotherapy equipment and the imported radiotherapy equipment, while the treatment cost of the domestic radiotherapy equipment is relatively low. However, the dosimetric parameters of organs at risk of imported radiotherapy equipment is lower and the acute toxicity is less..

Objective: To explore the clinical characteristics of glucocorticoid induced eye damage in children with primary nephrotic syndrome. Methods: The clinical data of steroid-induced high intraocular pressure or cataract in 49 children who were from Zhengzhou Children′s Hospital with primary nephrotic syndrome admitted from September 2016 to April 2018 were analyzed retrospectively in order to observe the relationship between relevant eye damage and clinical medication. Results: There were 37 boys and 12 girls in the 49 cases, of which the average age of onset was (7.6±3.0) years old, and among them there were 22 cases with glucocorticoid high intraocular pressure, 19 cases with glucocorticoid cataract, 8 cases with glucocorticoid high intraocular pressure combined with cataract, but no glaucoma in 49 cases.The shortest time of using glucocorticoid was 15-3 240 days[(863.33±871.46) days]; the cumulative dose of glucocorticoid was (7 865±3 691.66) mg/m², the left eye pressure was (26.68±5.95) mmHg(1 mmHg=0.133 kPa) and the right eye pressure was (27.71±5.82) mmHg.There was no significant correlation between glucocorticoid using time, cumulative dose and high intraocular pressure(r=-0.158, -0.264, -0.237, -0.361, all P>0.05). All the 19 patients with glucocorticoid cataract and 8 patients with glucocorticoid high intraocular pressure combined with cataract presented posterior capsular opacity, including 23 males and 4 females, and their time of using glucocorticoid was(1 296.67±903.35)days, who were followed up continuously. Conclusions Glucocorticoid-induced high intraocular pressure and cataract should be paid attention to by clinicians.Once high intraocular pressure or cataract occurs, the dosage of glucocorticoid should be gradually reduced or stopped, at the same time, ophthalmologic treatment should be actively performed to avoid serious eye diseases.

Objective To analysis risk factor and to construct a line graph prediction model for bone cement leakage after percutaneous transluminal vertebroplasty treatment in patients with osteoporotic spinal compression fractures. Methods A total of 236 patients with osteoporotic spinal compression fractures who came to our hospital from December 2019 to December 2021 were selected for the stud)', and they were divided into a leakage group (n = 58) and a non-leakage group (n = 178) according to whether bone cement leakage occurred after percutaneous transluminal vertebroplasty treatment. The clinical data were collected to analyze the factors associated with bone cement leakage; The work receiver operating characteristic^ ROC) curves of the subjects were drawn to analyze the predictive value of each relevant factor on bone cement leakage; The Logistic multiple regression model was used to analyze the risk factors affecting bone cement leakage; The R language software 4. 0 "rms" package was used to construct the prediction model of column line diagram. Results The differences in age, bone density, degree of vertebral compression, vertebral endplate/posterior wall integrity, bone cement viscosity, and bone cement injection volume between patients in the leaky and non-leaky groups were statistically significant (P< 0. 05). The area under curve(AUCs) for age, bone density, and cement injection volume to predict cement leakage were 0. 804, 0. 825, and 0. 803, respectively; The best cutoff values were 71 years, 0. 67 g/cm", and 4.4 ml, respectively. Age (>71 years), bone density (^ 0 . 67 g/cm"), vertebral compression (severe), vertebral endplate/posterior wall integrity (no), cement viscosity (low viscosity), and bone cement injection volume (> 4. 4 ml) were independent risk factors for bone cement leakage. The column line graph model predicted a C-index of 0. 802 (95% CI, 0. 689-0. 868) for cement leakage, with a threshold >0. 19, and the column line graph model provided a net clinical benefit. Conclusion Age, bone density, degree of vertebral compression, vertebral endplate/posterior wall integrity, cement viscosity, and cement injection volume are independent risk factors for cement leakage, and the column line graph prediction model constructed with these predictors is of clinical application.

INTRODUCTIONWilliams syndrome (WS) is a rare but well recognised neurodevelopmental disease affecting the connective tissue and the central nervous system. Many patients are identified through the presence of dysmorphic features and associated cardiac abnormalities. Klinefelter syndrome (KS) is associated with gynaecomastia, small testes, azoospermia and elevated gonadotropin levels. They are recognised in the second decade of life by their tall stature and delay in pubertal development. A combination of constitutive WS and KS has yet to be described.

CLINICAL PICTUREWe report a child with these genetic aberrations, highlighting the clinical characteristics of such an individual.

CONCLUSIONThe manifestations and interactions of both conditions are also discussed.

AIM: To investigate the influence of orthokeratology combined with 0.01% Atropine Sulfate Eye Gel on the recovery of myopia in children and the factors influencing the curative effect of children.

METHODS: Totally 200 children with myopia admitted to our hospital in 2017-03/2019-03 were selected. According to the requirements of children and guardians, the observation group(orthokeratology combined with 0.01% Atropine Sulfate Eye Gel)and the control group(only wearing orthokeratology)were selected. Totally 108 cases in the observation group were included in the study, 8 cases were abandoned after 6mo, and 100 cases were finally included to complete the follow-up. 92 cases in the control group were included in the study, 5 cases abandoned after 6mo, and 87 cases completed the follow-up. The patients' best corrected far vision, best corrected near vision, naked eye vision, intraocular pressure, pupil diameter and adjustment amplitude and discomfort symptoms after treatment were collected before and after 6mo.

RESULTS: The uncorrected visual acuity of the observation group after treatment was 0.12±0.05, and that of the control group was 0.19±0.07, which were significantly higher than those before treatment(P<0.05), and the observation group was significantly higher than that of the control group(P<0.05). After treatment, the intraocular pressure of the two groups had no significant change(P>0.05); the pupil diameter of the observation group after treatment was(7.01±0.66)mm, which was significantly higher than(6.09±0.69)mm before treatment(P<0.05); the adjustment amplitude was(14.06±4.03)D, which was significantly lower than(15.31±4.40)D before treatment(P<0.05); there were no significant changes in the pupil diameter and adjustment amplitude of the control group after treatment(P>0.05). Pearson correlation analysis showed that good myopia control was negatively correlated with age, uncorrected visual acuity and astigmatism before treatment(P<0.05). Multivariate Logistic regression analysis showed that myopia control was negatively correlated with age and uncorrected visual acuity before treatment(P<0.05).

CONCLUSION: Orthokeratology combined with 0.01% Atropine Sulfate Eye Gel is helpful for the control of myopia in children. The effect of treatment is influenced by the age of children and the visual acuity before treatment.

Objective: To explore the application value of digital 3D printing technology for repairing mandibular defects with fibular flaps and to provide a basis for accurate repair mandibular defects. Methods: Nine cases of mandibular defects were selected, and spiral CT and CTA of the lower limbs were performed before the operation. The osteotomy guide plate and plastic guide plate were created using computer software, and the titanium plate was rebuilt according to the printed mandibular model. During the operation, an osteotomy guide plate was used for mandibular resection; a fibula bone plastic guide plate was used to reconstruct the fibular flap and reconstruct the mandibular defects. Results: The entire fibula flap survived, and the occlusal relationship was good. There was no complications in the donor site. The patients were satisfied with the appearance of the repair. All patients were followed up for 3 to 6 months, at which point the bone was basically healed. Conclusion Using a digital 3D printing technique to repair mandible defects with a fibular flap can shorten the operation time, reduce the risks of operation, and better restore the maxillofacial shape and the function of the jaw, which is consistent with the concept of appropriate medical treatment. Additionally, this process provides a better method for the treatment of mandibular defects.

Objective： ：To investigate the expression of miR-137 in cervical cancer tissues and cells, and to explore its effect on proliferation, migration and invasion of cervical cancer cells as well as the mechanisms. Methods： ：Thirty-two pairs of cervical cancer tissues and corresponding para-cancerous tissues that surgically resected at the Department of Gynecology and Obstetrics of Dongguan People's Hospital from January 2017 to March 2018 were collected for this study. In addition, cervical cancer cell lines C33A, HeLa, SiHa and cervical epithelial immortalized cell line H8 were also collected. The expression of miR-137 in cervical cancer tissues and cell lines was detected by RT-PCR. miR-137 mimics and miR-137 NC were respectively transfected into C33Aand HeLa cells, and the effects of miR-137 over-expression on proliferation, migration and invasion of cervical cancer cell lines were observed by CCK-8 and Transwell assay. Luciferase reporter gene assay and WB were used to determine the relationship between miR-137 and Wnt5a in cervical cancer. Wnt5a over-expression vector was constructed, and the effects of simultaneous over-expression of Wnt5a and miR-137 on proliferation, migration and invasion of C33Aand HeLa cells were observed. Results： ：The expression level of miR-137 was significantly down-regulated in cervical cancer tissues and cell lines, as compared to para-cancerous tissues and H8 cells (all P<0.05). The over-expression of miR-137 significantly inhibited cell proliferation, migration and invasion of C33A and HeLa cells (all P<0.05). Moreover, Wnt5a was identified as a target of miR-137 by luciferase reporter gene assay. Furthermore, Wnt5a over-expression, to a certain degree, attenuated the suppressive effects of miR-137 on the proliferation, migration and invasion of C33A and HeLa cells. Conclusion： ：miR-137 can inhibit the proliferation, migration and invasion of cervical cancer cells via targeting Wnt5a, which may be an effective target for the treatment of cervical cancer.
