OBJECTIVE: To explore clinical effect of double plate technique in treating Neer 3 to 4 partial fractures of proximal humerus. METHODS: From May 2018 to December 2020, 38 patients with proximal humeral classified to Neer 3 to 4 partial fractures were treated with double plate technique and long head tendon fixation of biceps brachii, including 23 males and 15 females, aged from 41 to 89 years old with an average of (67.00 ± 9.76) years old;23 patients classified to Neer 3 fracture, 15 classified to Neer 4 fracture;the time from injury to operation ranged from 5 to 12 days with an average of (8.00±2.86) days. Degree of pain was evaluated by numerical rating scale(NRS) on the third day after operation; change of height of humeral head and angle of humeral neck stem were measured and compared between 2 days and 1 year after operation. Neer score was used to evaluate recovery of shoulder joint after operation at 1 year after operation. RESULTS: All 38 patients were followed up for 12 to 19 months with an average of (14.00±1.59) months. NRS score at 3 days after operation was (1.95±0.73) points. Fracture healing time ranged from 2.2 to 3.2 months with an average of(2.60±0.27) months. There were no significant difference in the height of humeral head and angle of humeral neck trunk between two days and 1 year after operation(P>0.05). Four Neer 4 fracture patients occurred absorption of greater tubercle of humerus and partial cystic change of humeral head, but the activity function of shoulder joint was good. Postoperative Neer score at 1 year was 89.50±5.19, and 20 patients got excellent results, 16 good, and 2 moderate. CONCLUSION Double plate technique and long head tendon fixation of biceps brachii were used to treat Neer 3 to 4 fractures of proximal humerus has good clinical effect, and postoperative pain was mild, without special instruments.

The patients were followed up for 2 to 20 months, and their symptoms and pulmonary function were improved significantly after lung lavage treatment. Our experiences showed that lung lavage with intravenous anesthesia is the most effective treatment for pulmonary alveolar proteinosis.

Objective: To establish a new method for the quantitative analysis of multi-components by single-marker (QAMS) to simultaneous determine seven components in Chrysanthemum indicum. Methods: The chlorogenic acid was used as internal marker to calculate the relative correlation factors (RCF) of caffeic acid, luteolin-7-O-glucoside, 3,5-O-dicaffeoylquinic acid, buddleoside, luteolin, and apigenin by high performance liquid chromatography (HPLC). The repeatability of RCF was investigated. The contents of seven components were determined by the external standard method and QAMS respectively. Results: The reproducibility of RCF was perfect. The value calculated by QAMS was consistent with the external standard method. Conclusion: The QAMS method for simultaneously measuring the content of seven components is feasible and accurate to evaluate the quality of Chrysanthemum indicum.

Objective To investigate the prevalence and genotype of thalassemia in high-risk children with thalassemia in Wuzhou, and to provide a reference for formulating strategies for the prevention and treatment of thalassemia and for reducing the incidence of thalassemia. Methods Four deletions and 3 point mutations of alpha-thalassemia and 17 point mutations of beta-thalassemia were detected and analyzed by GAP-PCR and PCR combined with reverse dot blot hybridization in children at a high risk for thalassemia in Wuzhou from 2010 to 2018. Results There were 1,421 positive cases in the first screening, and 871 cases were confirmed through genotyping, with a positive rate of 61.29%, including4 deletion types and 14 mutation types. There were 452 cases (51.89%) of α-thalassemia, 337 cases (38.69%) of β-thalassemia and 82 cases (9.41%) of combination of α-thalassemia and β-thalassemia. The common genotypes of α-thalassemia in children in Wuzhou were: --SEA/αα, --SEA/-α3.7, -α3.7/αα, --SEA/αCS αCS, αWSα/αα, --SEA/-α4.2, -α4.2/αα, and αCSα/αα. CD41-42, CD17, -28 and CD71-72 were the most common heterozygotes, while CD41-42/-28, CD41-42/IVS-2-654, and CD41-42/ CD71-72 were the most common double heterozygotes in children with β-thalassemia in Wuzhou. The most common homozygous genotypes were CD41-42 / CD41-42 and -28/-28. Conclusion In order to control thalassemia it is critical to increase investment in large-scale screening of carriers of the thalassemia mutant gene, and to prevent the birth of children with severe thalassemia.

Dental implants have become the main choice for patients to fill in their missing teeth. A precise placement is the basis for a functional and aesthetic restoration. A digital surgical guide is a carrier that transfers the preoperative plan of dental implants to the actual surgery. This paper provides some references that can help clinicians improve the accuracy of implant surgery by stating the development, classification, advantages and disadvantages, and factors that affect the accuracy of digital guides.

Objective : To compare the accuracies of implants with dynamic real-time navigation versus digital guide navigation to provide a reference for clinical precision dental implants. Methods: Forty-six cases (seventy teeth) with missing teeth admitted to the Department of Stomatology, Wuzhou Red Cross Hospital from April 2018 to December 2019 were randomly divided into two groups (thirty-five teeth in each group) for dynamic real-time navigation and digital guide navigation implantation techniques. To compare the entry point, apex point, depth and angle deviation of the preoperative and postoperative position of implants in the two groups. SPSS 21.0 software was used for statistical analysis. Results : Dental implants were successfully placed in both groups. The deviations of apex point, depth and angle in the dynamic real-time navigation group were all smaller than those in the digital guide navigation group, and the differences were statistically significant (P < 0.05). There was no statistically significant deviation in the entry point between the two groups (P > 0.05). Conclusion In this study, both techniques had good clinical effects. The accuracy of dynamic real-time navigation was higher than that of digital guidance.

Objective The aim of this study was to establish a rat model of irritable bowel syndrome.Methods Thirty healthy adult SD rats ( mele:female=1:1 ) were divided into normal control group, model group, and positive control group ( pinaverium bromide tablets 15.0 mg/kg) for 31 days.Body weight, appetite, defecation, voluntary move-ment of all the rats were determined.The rates of gastric emptying and small intestinal propulsion rate were measured.The serum 5-HT and plasma SP and VIP or 5-HT, SP, VIP in colon homogenates were assessed by radioimmunoassay.Blood biochemical parameters were measured with an automatic biochemical analyzer.The gastric and intestinal morphology was evaluated by histological examination.Results After modeling, the rat weight and food intake were decreased, ad stool quantity was increased.The voluntary movement and gastric emptying rates were decreased, intestinal propulsion rates were increased, and the contents of SP and VIP in blood were decreased, but increased in the colonic homogenate (P＜0.05, P＜0.01).After treatment, the food intake was increased and stool quantity was decreased, the rat body weight was signifi-cantly increased, the amount of voluntary movement and stool returned near to normal, the 5-HT levels in serum or in co-lonic homogenate were significantly decreased, but plasma VIP levels were markedly increased, and the SP and VIP con-tents were significantly decreased in colonic homogenate in the positive control group (P＜0.05, P＜0.01).Hematology indexes had no obvious changes.The gastric and colonic tissue morphology showed no distinct damages caused by the di-verse stimulating factors.Conclusions The stimulation of composite factors can be used to successfully generate the rat model of irritable bowel syndrome, showing similar clinical manifestation of this disease in humans.

In the folk medicine, it was believed that the raw Sanqi could remove blood stasis, swelling and pain, while the cooked Sanqi could replenish blood. This article began with the first record of Sanqi in ancient herbal medicine literature, and the nature, flavor and efficacy of Sanqi, then listed the processing methods and usage of Sanqi recorded in ancient herbal medicine literature, and compared with the modern processing methods. The results showed that the processing methods of raw Sanqi included making powder, chewing, vinegar grinding and wine grinding, in which the method of making powder was still in use, and there were particle size requirements on the Sanqi powder listed in most modern preparation specifications. The processing methods of cooked Sanqi included baking, frying and steaming, in which the method of steaming was still in use, but had some changes. The new processing method was frying with edible oil. The results clarify the history of the processing of Sanqi, and provide a reference for the research and application of the processing methods of raw and cooked Sanqi.

To study the effects of fresh-cut drying methods on the appearance and internal components of Panax notoginseng, and explore the feasibility of fresh-cut drying methods of P. notoginseng, so as to provide more effective processing methods for the production of P. notoginseng slices and Chinese patent medicines. In this study, we have compared the effects of 6 different drying methods on drying time, drying rate, density, appearance and internal components of P. notoginseng roots. It takes about 453 h to dry by whole-root drying in the sun, with a long constant speed period and a slow drying rate, the time of whole-root drying at 50 ℃ was shortened by 61.6% compared with whole-root drying in the sun, which resulted in the decrease of density and poor appearance of the medicinal material with hollow and crack appeared in the xylem, while the drying time of fresh-cut drying method was reduced by 61.82% to 91.58% and the drying rate increased greatly, due to the relatively slow drying process in the sun or in the shade after fresh-cut, salting-out and whitening appeared on the surface, and the internal components were all decreased to some extent. The drying time of fresh-cut drying at 50 ℃ was 91.58% and 68.83% shorter than that of whole-root drying in the sun and at 50 ℃, respectively. When drying at 50 ℃ after fresh-cut, the appearance and content of internal components of the medicinal materials were better, the appearance was yellowish green, the cut sections were clear with uniform pore distribution, and the content of saponin components was increased by 7.24% compared with that of the whole-root drying at 50 ℃, When drying at 40 ℃, the surface of slices has salting-out and whitening spots, and the loss of dencichine and total sugar was large, but at 60 ℃, this high temperature made the rate of dehydration of slices was extremely fast, which led to severe cracking and fragmentation, and the loss of total sugar and alcohol extract was large. By vacuum freeze drying after fresh-cut, the structure of medicinal materials slices was loose, the density was greatly reduced, and the appearance was different from those recorded in traditional books. The contents of total saponin components and dencichine were increased by 16.51% and 22.54%, respectively, compared with traditional whole-root drying. The fresh-cut process method is feasible in the production of P. notoginseng slices. In production, it is recommended that drying at 50 ℃ after fresh-cut can make the medicinal materials better in appearance and content of internal components, which is convenient for the subsequent processing and industrial feeding extraction. For the purpose of internal contents, it is better to adopt freeze-drying after fresh-cut processing method.

The aim of this paper was to explore the effect of Xueshuantong Injection(freeze-dried powder,XST) on κ-carrageenan-induced thrombosis and blood flow from the aspects of interactions among blood flow,vascular endothelium and platelets. Fifty male Sprague-Dawley rats(190-200 g) were randomized into five groups: control group, model group, heparin sodium(1 000 U·kg~(-1)) group, low-dose and high-dose(50, 150 mg·kg~(-1)) XST groups. Rats were intraperitoneally injected with corresponding drugs and normal saline(normal control and model groups) for 10 days. One hour after drugs were administered intraperitoneally on the 7 th day, each rat was injected with κ-carrageenan(Type Ⅰ, 1 mg·kg~(-1)) which was dissolved in physiological saline by intravenous administration in the tail to establish tail thrombus model. The lengths of black tails of the rats were measured at 2, 6, 24 and 48 h after modeling. Vevo®2100 small animal ultrasound imaging system was used to detect the internal diameter of rat common carotid artery, blood flow velocity and heart rate, and then the blood flow and shear rate were calculated. Meanwhile, the microcirculatory blood flow perfusion in the thigh surface and tail of rats were detected by laser speckle blood flow imaging system. Platelet aggregometry was used to detect the max platelet aggregation rate in rats. Pathological changes in tail were observed through hematoxylin-eosin staining, and Western blot was used to detect the protein content of platelet piezo1. According to the results, XST could inhibit the rat tail arterial thrombosis and significantly reduce the length of black tail(P<0.05). The blood flow of common carotid artery in XST low dose group was significantly higher than that in the model group(P<0.05). XST high dose group could significantly increase the microcirculatory blood flow perfusion of the tail in rats as compared with the model group(P<0.05). XST high dose group could significantly inhibit platelet aggregation rate(P<0.05) and XST low dose group could significantly inhibit platelet piezo1 protein expression(P<0.01). In summary, XST could play an effect in fighting against thrombosis induced by κ-carrageenan in rats, which may be related to significantly inhibiting platelet aggregation, improving body's blood flow state, maintaining normal hemodynamic environment and affecting mechanical ion channel protein piezo1.
